can the IS300 stock rods handle 550hp!? Do I need to do my rods or will they hold the power I want?

Yeah, no, unless you guys got stronger rods and pistons in Straya than we did in the States. 550hp would not last very long imo. You’ve got a nice ride, and a nice parts list. Spend the money/time and get at the least GTE rods and pistons. You could upgrade to aftermarket stuff too.

I’m gonna offer some unsolicited advice too, haha. I’d advise getting some larger injectors for headroom. You’ll be able to get close to 550hp on 550cc but they will be near max DC. Never good to run stuff to the ragged edge. And if you haven’t bought that boost controller - don’t. Your Haltech will do a good job and all it needs is a Mac boost solenoid.

Got any more pics of that J pipe turbo set up? Or under hood pics?

Hehe, I see thanks for that bud, boost controller is the OLED Greddy II not hooked but my reputable tuner said hook it up I need it for the tune. Ok here some more pics.

Ehh, “need” is subjective. The OLEDs look cool and do work. Depending on the install, haltech will let you do some cool stuff with boost, like boost by gear/speed and boost regulated traction control.

Thanks for the pics, that’s pretty cool looking. Bet that downpipe was fun to fabricate.

Bro the downpipe was the nightmare

. For the piston and rods does the top end need to come off!?

Yeah I can imagine that downpipe being terrible. Lotta shit in one area to have to account for. I’ve seen a thread here where a guy did pistons/rods from under the car. I would pull the motor and head if I were doing it but that’s just me.

That is a huge turbo. Definitely will make all the top end you want. I am just here to second Kris. Step number one. Get 1000cc injectors please. Step two, upgrade to AT LEAST GTE rods and pistons. At this point it might be worth spending the extra money on aftermarket rods and pistons.

See that’s where I wish companies would just all stick to one style of numbering convention. A BW 8376 is the same as a s362sxe or if you go with Precision’s numbering style it’s a 6268. So it’s not a real huge turbo but you’d think it would be based off that 8376. It’s the same turbski I’ve got on my gte.

It spools very smoothly and strongly and has a sexy hissing sound to it. Love the T51 mod these turbz have!.

I’m definitely getting the GTE rods and pistons. Found a used set in great nick for $400USD

Catch can to be installed tonight

Yeah I like how mine sounds. Almost like a jet or dentist drill. I can’t imagine what it would sound like with a T51R mod. Too loud.

400$ is good price for gte internals.

How’re you doing your catch can? Mine froze last week, the crankcase couldn’t relieve pressure, so the turbo drain backed up and caused oil to leak at the rear of the turbo and burn. Smells amazing still hasn’t burnt all the way off. I’ve got a line pre-turbo to the catch can then line “Y’ed” to each cam cover. Best way to do it on a turbo car and keep pressure out.

Mishimoto can. Well man we were below freezing for 10 days and got down to -8F, you need to empty the can more often in winter because more condensation occurs in cold weather. I got lazy, can/lines got water in there and froze. I knew what happened soon as I smelled the cooking oil, and loosed the oil fill cap so it could vent the case. Turbo seals are like stepped-gap piston rings, so they’re fine no leaks. Cars fine, just stinky til the oil burns off. Lesson learned for sure!

Anyone know if Aristo cams will fit the IS300? And their HP rating!

That's terrible, was your catch can completely full?

Even if it was halfway full, let's say if it has two fittings on the top (inlet and outlet) it should have been able to flow through the system well-enough. Also, as you drive the warm vapours should be heating up whatever amount of fluid you had in your catch can reservoir, slowly turning it into vapour again.

Unless it froze in some other way?

Yeah nah not full at all, it’s one of those little Mishimoto clone catch cans, maybe had like 120cc in it. Problem was the “vacuum” line that went to the pre turbo intake, had some slack (low spot) and so vapor must have got past the can, condensed/pooled in the line and froze. Crank case couldn’t vent and so it pushed oil past the turbo seal. It wouldn’t thaw dude it was so damn cold we didn’t get above 32F for like 10 days.

I believe they will drop right in, but I have no idea about the difference in power band. I’ve got a set of VVTi GTE cams I would give you for free mate, they’ve been sitting since I went GSC S1 last year. I’ve read on Supra sites that they are the same cams even, GE vs GTE but I don’t know if that’s true. Without having them side by side to compare it’s all anecdotal. Honestly if your swapping cams, and therefore shims, I’d get a good set of aftermarket cams (BC, GSC, HKS, etc). It’s a pain to have to reshim so you should do it up the first time - but I am not the one spending the money.

I've read that the Aristo cams aren't much bigger than the stock GE VVTi cams, but they should fit fine. You probably won't feel much of a difference, but that's just speculation.
