more power

[eternalboost]

i just picked up a 88 turbo supra. it's got 175,000 kms racked up, but runs great (for being stock). i've been lookin on SM and see every body uses 3" exhaust. what kind of gains will i get with a 3" system with no cat? do you need cold air intake to make any difference? my friend has 3" exhaust and headers on a 93 mustang gt and he pulls past me, about 3-4 lengths on a 1/4 mile, this is unacceptable! what else can i do to gain modest power before i rebuild next year? more boost would be nice, do i need a controller for that? also theres a bit of blue smoke on start up when it sits for a few days but goes away in a few seconds.

Full 3 inch exhaust system. From the turbo back. A lex AFM and 550 CC injectors and crank the boost up to 15 PSI.

Bye bye mr mustang.

maybe 10 hp but your turbo will spool quicker due to less restriction

10 HP from a full intake system and exhaust is inaccurate. You will make ALOT more power than that.

A NOTICABLE difference in boost and power can be easily achceived by adding and intake and exhaust.

Intake, exhaust and 14-15psi is very close 300rwhp and sometimes even more .....

my 91 mods were; cat-less full 3 inch cat back, blitz intake. i was stickin it close to mustags. all i was missing was a kik in the boost from stock to about 13 and i would've won almost everytime.

With 14psi I have personally out ran the new mustang gt's, charger RT's, srt4, non turbo porshes, older m3's I would say there were 96-99's, and a bunch of import compact cars.

When you turn your boost up the car will feel like a different animal. I turned my boost controller off once i was ohh hell naw ... Stock boost is nightmare.

Just keep in mind the miles on your car are very high. So dont be surprised if that rebuild comes closer than next year. When you do the build get an upgraded ct26 57 trim and 550's and you will smoke almost all the cars on the road.

Head gasket and ARP's first! lol
(or at least a re-torque)

then start on power mods

Also, the start up smoke is probably valve seals. (all my supras have done it)

Boost controlers are TROUBLE. Do not get one. The car will raise the PSI accordingly to your mods. Let the car do the adjusting itself.

No offense, but it doesnt seem as if you know to much about your car (yet) or modifying it. A boost controller will only bring problems.

Dude wtf are you talking about? EBC are the best way to control boost and there is no debating that. When the winter comes and the car has some boost spikes because of the cold weather how will he be able to turn down the boost? Think about it his mods they should allow him to boost 10psi or so naturally but what happens if his boost spikes to 13psi and he keeps hitting fuel cut?????

So what if he does not know alot. I guess you are the only one born with all the car "know how" in the world .....If he turns up the boost to much he will hit fuel cut(spark cut) which will keep him from blowing up his motor. When you hit fuel cut turn the boost down and its all good. Its that simple

From my recall, he never said EBC.
