My advice would be to get a 1/2 stage from each.

...Though you pay more for Toyomoto you get double the horsepower and a PERFECT running vehicle...Hectic_1 Tampa has had NO porblems and he boosts almost 18 psi daily driving....Thats also double what the SRT and PFS kit do for stage 2....ONly thing is Toyomoto is NOT shippable and you pay more....but craftsmanship is much better as I have seen both kits in person ......I do not speak being a Toyotmoto customer...As I have left Toyomoto and went with Auto Tuner for personal reasons....but Toyomto is just the better pick here....You get what you pay for i think...

safest, reliable and most powerful stage 2- toyomoto & PHR
they cost a lot, too($12,500/11,500)

'stages' doesnt mean shit, as those 'stages' are nothing more than each tuner's own standard.

rather than being tied up on 'stages', you should consider:
-reason (max power? uber quick response? location of the powerband?)
-target hp
-budget
-proximity of the tuner (maybe)
and choose whatever is close to your need.

safety and reliability is almost a given. the 2jz engine is 10+yr proven engine, and i know the tuners spent tons of hr R&D'ing(reseach and development, not rip-off and duplicate)

power is little different. each tuner's power characteristic is different. its not a matter of 'good' or 'bad', but just a personality of turbo's. for example, SRT stage 4 has 700hp, but it has less area under curve than PFS stage 3 which produces about 600hp. pick what you like.

every info's are already in the forum. so do some research and you'll have EVERYTHING you need.

Yeh, you should do a search.

Just be prepared to replace a tranny if you got a manual and some pistons if want to run much over 400 rwhp on a daily basis. Factory internals have been failing at these levels. If we dont boost it more that 15 psi we all might get some descent mileage and reliability. There has just been a number of Turbo IS's popping up with cracked pistons. So just be prepared.

I'd be curious to all those with cracked pistons if they had the 2001 cars or 2002-up cars? I remember Freelance had a side by side view of the rods from a 2001 & a 2002 and the 2001 rods looked a little beefier (wonder if it's the same with the pistons). To all those who have had cracked pistons running about 15psi or so and putting about 400 rwhp what year IS300 do you have?

Two words: Engine management.

This is what separates the men from the boys. If you are going turbo, do it right the first time and get a real ECM.

That said, if you want a shippable kit, PFS is the only way to go.

no one has mentioned TBKO, I think there stage 2 is the best value for the money. It produces much more hp than an SRT stage 2 b/c of lowered compression, and it's $700 cheaper to boot. Power wise it's not quite up to the stage 2's from Toyomoto or PHR, but if that's your budget, you can't buy more power for the money, hands down. :wink:

I think you could have a completely installed TBKO for under $7K, now that's a deal. Of course, for all these kits ,you have to add in the extras, like gauges, boost controllers, exhaust, etc. So the actual cost is always more.

If you have the money, Toyomoto and PHR do very high quality kits, though. My plan is to have PHR do my install and tuning if possible, they're the closest shop to me.

Dont get me wrong, toyomoto makes great kits, but if you have an auto pfs is the way to go. If you go with toyomoto powerhouse or pfs you cant go wrong. They all are extremely experienced tuners. You should really look into whether the haltech, motec or the tech 3 suits you the best.
