You should tell your friend that an intake and FMIC does almost nothing for power. Exhaust does a little. He probably gained 5-10whp, almost nothing. What he also needs is dp/dp, and a tune. Infact a big front mount will actually increase the lag of the stock turbos.Quote:

Also an exhaust is a huge upgrade on most turbo cars, since from the factory most turbo cars are restricted due to noise, and emissions.Quote:

The only statement that is somewhat true is the turbo lag. Yes, a larger intercooler has more volume for the turbo to pressurize, but because they don't get heat soaked like a sidemount would after hard use, this negates that downside. Seriously, I didn't notice any difference in turbo lag on my car when I upgraded to a larger FMIC with larger piping, and that's a 4 cylinder. I've seen BPU twin turbo Supras run into the 11s on full bolt ons, tuning, and tire. Trust me, you are gaining more than 5-10whp from these parts. Yes, I understand most of the power is accented by turning the boost up, but the upgraded parts makes the car run for efficient at high boost, hence more power, hence ... you go faster.
All the supra forums i was on said that with a stock setup that upgradeing the IC to a FMIC gains very little until you turn up the boost. I dont know personally because when i dwapped out intercooler on my supra i also did a full engine rebuilt and turbo upgrade but mine was also a 87.Quote:

So without a tune and just a upgraded intercooler you dont gain much. Just like the legacy top mount to front mount swap. The only power you do gain is if your previous intercooler was horribly inefficient and the stock tt sidemount actually did a good job. Hell i took a 89 intercooler to 370whp without problems i cnat see the 2jz intercooler being worse. Also my sidemount didnt get heatsoaked from hard use, it got heatsoaked from stop and go traffic or time when the car wasnt moving, same with my topmount on my legacy it only gets heatsoaked when in stop and go traffic when im moving even at the track it stays pretty cool.
I know the 2jz tt supras could make 400+ crank hp on the stock twins but those turbos are limited to 18-20psi. Yes if you were going to be running more psi than stock a FMIC is never a bad idea and full bolt ons. But the mods he listed said nothing about a tune, so i figured why have those bolt ons but no tuning to get the power out of them.
This is a post i copied from this page

Some people go on to say the TT 2jz intercooler is good too almost 400whp.
"I added a Greddy FMIC on my 97 BPU supra. and gained a whopping 8rwhp and lost 1 lb/tq. given that the temperature might have been different, my last dyno was 2 years ago at 382rwhp, this year 390rwhp with a slightly smoother fuel curve and the FMIC. there was a huge fan blowing, so aside from enviroment variables, the gain was not that big at all. Im sure piping diameter plays a huge part too, but the supra plumbing is already very adequate."
