I want to start a post just to see what all issues ppl have run into while trying to boost their car.. The good the bad and the Ugly...

This will give ppl an idea of what not to do and what would be a better route, it would also let some boosted IS owners talk amongst each other and get ideas off one and another. If everyone who is boosted COULD BE HONEST AND FORTWORTH, I think it will help others in their quest for more power. So screw the tuners on this post, after all it is your money and NOT theirs so no glory for the tuners and lets make this a Owners post only..

So here we go..


I haven't had many issues, more like really bad luck...

First car 01 boosted IS300 w/ a little over 500rwhp... I let a buddy drive the car at the drag strip and there was a mishape and the car ran into the wall at 110+ = totalled sitting in a junk yard.

Second car, had everything put back on plus upgrades, only to fuk up and get caught massive rain storm and I get stuck in a HUGE puddle that got water sucked up into my block, which in tern bent 2 rods and did block damage. I calimed insurance and they fixed it, because it was water releated so mother nature was to blame...

I had a 5spd, blew that in 3rd gear on 11psi, quickly put in 6spd and I have had NO issue what so ever w/ that getrag...

Recently I got race fuel from a reputable fuel company only to find out that it had water or some other liquid in it besides gas that blew my spark plug and damaged my # 1 cylinder. I got major pinging and detonation when I was at the track but I never felt that before so I just kept on driving. Didn' notice any major problems until I was leaving the track and racing a high 10sec mustang, after beating him twice, at the last run I heard a loud pop in 6th gear at 130mph'ish. When that blew I noticed the car jerking when I would get around 4000rpms, and then I hear what sounds like nuts and bolts in a coffee can rattling around in my b-pipe. I retard the timing back to its orgional settings and drive home slow. I let the car run till it emptied all the Race fuel and then put in pump gas and like night and day the car was back to normal, until i pulled the plugs and saw the damage.


Other than that havn't had many issues from the car.. But of couse my work is never done which as a lot of you know is CRAZY expensive.. So if you want a boosted IS300 w/ a lot of Horse power: Get a good Job :lol: :lol: :lol:


So if others could tell your horror stories the good and the bad, I am sure others would appreiate it..

Blowing my tranny was a big pain in the ass, seeing that I just dropped a lot of looch on the turbo kit a month before that. I guess I'm happier now because I don't have to worry every time I boost the car if the tranny will hold.

Then I cracked my stock pistons and put in TT internals. I had just recovered from paying for the tranny at that point. The tranny and internals took my money for coilovers and wheels. I guess I'll have to settle for the sleeper look for a while.

1. Dated a girl for a few weeks, got bored of her, month later she keyed f**k you on my hood and keyed around the whole car, whole car got repainted.
2. Totally destroyed my differential when I had my srt stage four kit, do not do donuts and long burnouts for show like my dumass did as soon as I had boost. Went with a different tuner for personal reasons and decided to chuck the auto install the getrag and supra rear end to avoid any future driveline problems.
3. First day I got my pfs stg 3 I was boosting at 13psi in first gear and did 3 360 spins flew over the median and destroyed intercooler pipe and lip of 540hre wheel :pissed: Too much torque with an inexperienced driver :oops:
4. Shattered a few rods on the dyno at 28psi on the dyno friday evening (stock bottom end) pfs put tt internals and new head within 24 hours and ran 11.4 on sunday :crazy:

So far so good, to avoid problems associated with winter I will be parking my car in a relatives garage all winter.

Lets see not having a car for awhile and the million "wheres your lex at?"

Having to be tooo nice to my girl who was my just about my only ride to/from work, most of the time she was being a biotch b/c of the situation.

Having to fix my beater and drive my lovely 1986 jimmy with 270,xxx miles everyday.

Thinking that the IS in stock trim is great for boost, hmmm :-? seems as though blocks and trannys are dropping like flies

Having a possibly cracked piston (seems to be the most likely) on a stage I running 6/7 psi

Knowing that the new GTE blocks suck and need to be intensely checked for possible failures and goodluck to those who go after the toyota warranty.

Knowing that my tranny is not safe for boost and having to save up for a 6 speed swap.

And last trying to find a mother fockin trailer to take my car down to PFS and have it looked at.

Damn, you too? That sucks!!! We'll have to see how long my TT internals last.

Yeah, I could make the drive down to the shop blind folded.

First problem was with the charger its self. A washer or screw backing (some peice of metal) came loose in the charger and bent the compressor blades.

A few months later while at the track the insulator of the spark plug, better known as ceramic, cracked in a complete circle, forming a ring. this ring lodged itself in between the center electrode and ground electrode (i know, hard to believe, but i can send you a pic if you don't believe me) this lodging of insulation caused the car to misfire, and i would speculate, also caused a build up of fuel in the cylinder, which ultimately lead to the death of cylinder number 5. So the number 5 piston had a broken ringland.... I opted to buy a very low mileage IS300 motor.

I found these two issues annoying because I never dreamed I would have problems with a S/C unit while only putting down 274 rwhp (at the time).
So for anyone looking into any type of F/I have money to spare!!!!
Also be prepared for issues along the way..

Being the dumbass like most of you think I am.....

I decided that due to the previous "tuner wars" that ocurred over the past years. I was not completely satisfied with the type of product that was being offered by ANYONE. I had MANY unanswered questions and many loose ends were not tied up.
I have had a deal go sour due to unforseen circumstances.
I decided that the only solution was to make my own turbo kit :crazy:
I have been working months on end in my spare time designing, asking questions, working with a select few .netters i trust, asking other DIY tuners, asking the pro's who are willing to help me their advice.

I have learned by turbocharging my VW in paralled with workin on my own IS300 kit that it is not as easy as it may seem. It does take a lot of work and a lot of tools to make it all come together. the $7000 sticker prices that IS300 tuners were quoting did not seem that far etched after I tallied up my receipts.

All in all its a TON OF FUN (If you got the time, skill and support) I feel so much more confident in reading widebands, fuel maps, compressor maps and tuning a standalone ECU after this project has gotten underway. Its a lot harder than it looks to make all the stuff that you get in your turbo kits, not to mention expensive, but its fun trying.

Oh well my boost is nearing....

Well, my car has been super strong and runs very well since the day I got it back. Only problem so far is a tiny coolant leak near the water pump. When the radiator fan starts blowing I get coolant all over the place. Then I go into a WINO rage and yell really loud! :-?

But that is all getting sealed up and fixed when the stage 2.5 goes in. :D

The other thing would be the tranny, even though my stock runs smooth and strong, I am going with the 6 spd to take away the fear of driving my car hard and a better peace of mind. Once this is all done, I can imagine the next thing would be to replace my internals...still debating on doing this during the stage 2.5 install...not sure yet.

I haven't had any major issues, but I'll list the small ones I do have:

1. The engine takes about 3-4 seconds of cranking to fire up. This can be tuned, but I haven't found the proper settings for starting enrichments yet.

2. The car shifts crazy hard when cold, I have to let it warm up a little bit so it shifts softer. Just a tranny oil temp thing and line presure being high. Hey, at least it shifts!! :lol:

3. I blew out a wastegate gasket do to not tightening it enough, bolts were loose. Found that when I took my Throttle body off last weekend. Self install, mah bad.

4. When I first put the kit in, I gapped the plugs to much at .040", this caused me to start misfiring at high rpms. I fouled the plugs basically. Asked PFS, they said to gap at .025". I bought new plugs, gapped to .025" and not a misfire since.

I've had the kit on for about 6-7 months now and these are the only issues I've had.
I drove to San Jose from Seattle and back, by myself, in 115+ degree weather, through mountain passes at 90+ degrees, not a hint of overheating or detonation. EGT's never read more than 800-825c. Not bad for no FMIC.

Pretty good considering it was the first PFS stage 1 kit sold to a customer and also the first to be installed in a driveway. It's been pretty damn solid and reliable as I could want. :D

So far I have been pretty lucky. With about 2000mi on the turbo system I noticed some oil around my engine compartment. Found that oil was being blown out of the blow off valve. However the car was driving perfectly, made boost, no excessive lag etc. Took the car in to Toyomoto and the found that the impeller on the exhaust side of the turbo was damaged. Something had gotten in and clipped most of the impeller. Toyomoto replaced the complete turbo even though they would not be able to return it because the problem was not a manufacturer defect. Not only was the car up and running the same day but while I waited Lance bought me lunch too!!! Toyomoto swallowed the cost of the new turbo even though it was just one of those 'freaky' things.
The car always ran great even with a damaged turbo. It's been 9000mi since the car was turboed (6000mi with the 2nd turbo) and no problems whatsoever. I have really enjoyed having a boosted car. I hope my 'good' luck continues.

Here goes the story of 5 months w/out my car... :cry:

1. (2002 November~2002 December) took area51 one month to get the kit ready while my car just sitting there hearing "ur kit will get started tomorrow" for that whole month. :roll:

2. (2002 December~2003 January)took them another month to just pro-fit it in and install/dyno/tune. :x

3. (2003 January~ 2003 Febuary)they forgot to tell me to fill up the gas tank to reset the gas-needle in the gauge cluster when i picked up my car on 1/17/03. So, i thought i'd quater tank all weekend-long for the first weekend i got my car back. On saturday night 1/18/03, the car ran out of gas, i didn't know that, try to start the engine N times. Then when the car got tow to area51 the monday after, they found out my compression was hella low. Took the engine out, found out 1st & 6th pistons were damage, and some damage on rod too. :whine:

4. (2003 Febuary~2003 March) so they suggested me to re-do my internal since the eingine's already taken apart. Took them a month to get the internals i wanted (maybe i was asking too much, but now i do feel glad i've a fully built blue-print motor), then install/test run/break-in. Then, 2 weeks for the s/c put in, re-dyno/tune. :bitching:

5. (2003 March) During that 2 weeks, area51's going through their last few days of business, my car almost got impounded w/ the building and some of those cars that were there w/ mine. :shame: (thanx to Dr.Charles pulling my car out from there right before it happened)

Nevertheless, lesson i learned = don't try to start a car when out of gas. :oops:

However, the result = World's first 3.1L custom built motor w/ JUN custom internals + one-of-a-kind custom supercharger :crazy:

PS. Planning to have my custom kit go into production through a reputable shop w/ Dr.Charles' Tech Support. For more info about the kit, click my Sig and go 2nd page. 8)

I've been down an interesting road so far with the IS. My car got started in December of last year. After 2 weeks, I had an intercooled stage I and took a trip to my parents (Atlanta) for xmas. I got a speeding ticket xmas eve in NC (the 2nd day I had the car back) for 83/65 :pissed: and the car ran fine. The shifting was a little rough, but it was bearable for the trip. I got a Valentine from my parents for xmas that year (Yay!).

Returned from that trip in early Jan. I drove the car for a week or so and then dropped it off to have the rest of the stage II work completed. Part of the kit included the auto tranny upgrades. Being one of the first (if not the first) auto's at PFS, my car was in the shop for a few weeks while everything got mapped out. The car shifted well and the was fastest thing I'd ever driven on 4 wheels.

I got the car back again in Jan. and drove it around with no problems for a few weeks when it wasn't raining or snowing. Went on a road trip with some friends to Miami (thank god for the valentine!) in March. Followed a truck @ ~100mph or so for 30-45min that we later found out via the amber alert system was a kidnapper (thus his high speed).

The rest of the trip was plagued by 100+ degree temps where VA was still in the 60s. The car ran very rich and stalled at inconvenient times, like on a drawbridge(there was pushing involved, the natives were very helpful) or at lights. The car ran great at night (only in the 80's) and it was fun taking it down the strip(blingity bling bling bling!) and to the beach. On the way back, we stopped at a gas station in northern Miami around 3pm. I couldn't get the car started again until after 9pm when the temperatures dropped. After the car got running again, we made a b-line for the border and stopped in Jacksonville around 3am.

Next morning, I drove the car over to the waffle house and parked. We ate, and I couldn't get the car started again. Armed with my laptop, I called up PFS who did some troubleshooting with me over the phone and determined that the problem was the crank sensor. I crashed at a $24.95/night hotel (where the car was parked near the waflle house) and PFS overnighted me the tools and parts to replace the sensor. I did it in about 15mins at 8:30 the next morning. The waffle house employees were very curious. . .but I got free coffee :lol:. There were no other problems the rest of the trip home (again, thank god for the valentine). After a quick 2 day checkup, I got the car back and drove it until we went to Englishtown problem free.

I watched my car put out 494rwhp on the dyno 10:30 the night before. It was pretty cool. I had been riding my bike and left the car at the shop for the week to get prepped for the race. I went home around 11 and was back at PFS at 7 the next morning. The trip included two tires (et streets), a 30gal. drum of vp, a bunch of tools, jack, etc. The car was so packed we couldn't see out the back. The ride up was fun and uneventful (no cats, 3" exhaust, flourescent green stickers, the car was loud!).

We got to the track, fought with the ticket people and finally got to go qualify. 11.8! Unfortunately, the car had thrown a rod. After one pass the motor was kaputz. The nice people from MSP trailered it home for me.

New engine was put in and I haven't had any problems since then. . . until a couple of weeks ago. I have one, if not many, cracked pistons. We found lots of oil coming from the intake (my bov is plumbed back into the intake) on our Mountain drive meet. The car wouldn't build much more than 13 or 14psi on the trip either (probably due to pistons).

Now I'm planning either a gte bottom or forged rods/pistons on the ge, cams, return fuel line, pt67(maybe), 3" exhaust and a transmission upgrade. I think this should cover most of my needs for a while.

Like Randy said, this isn't a cheap "hobby", if you can call it that. The hunger for more boost is fed with cash, and you never get full. The faster the car goes, the faster you want it to go. There's no end and luckily, with our cars, there's no end to what you can do.

This ended up being a longer read than expected. Hope you guys don't mind.

what are these cracked pistons?

to me a cracked piston is one piston that becomes more than 1 piece, the metal actually cracks and a piece chips off. i could see that happening from cylinder pressure

if the piston is melting, or deforming and rebonding (melted or pinched ring landing) that is NOT due to the weakness of the pistons, its due to tuning. the aluminum is brittle, it cracks under pressure, it does not melt. it would deform or melt from incorrect tuning most likely, or not enough control over the vvti, if it is still being used

does anyone have pictures of these pistons, i'd like to see what is actually happening?

maybe when i have time, i'll write a trials and tribulations of the GTE swap in this post

the bad was having my number 3 piston cracked by someone else. That was fixed by putting in the gte block. Waiting forever for someone to pickup the car to ship to pfs.Don't use Intercity Lines for shipping a car

The good was the power getting qualilty work done at two shops PFS and Sound Performance and hopefully more power and reliability when the car goes back to PFS next week for more upgrades

So what do you think about 6 cracked ringlands? They are not deformed or melted. They just straight cracked through.

i need to see pictures

did the top ring crack in half, or in pieces, or did it grind itself away or what. its very hard to do anything without at least seeing pics

if there was no metal deformation, as in it kept its general form to some respect, but was deformed, than it was not from tuning

it could still be related to vvti and cylinder pressure, but that would just mean that the added pressure is exposing a weakness somewhere
