What is the cheapest, fastest way to gain BIG HP?
 

I want to know what kind of upgrades can I do without changing the turbo to get maximum output of my 7MGTE? As of this moment, I have a K & N Air Filter, HKS Blow off valve, Megan Downpipe and Trust exhaust. Turbo is currently set at 8PSi. What else could I do to make it run more powerful and yet safe? Thanks!


PS. Thanks to those who contributed to my other help thread. It was the TPS and the screws were loose. Thankyou!

the next best thing you could do would be to upgrade your intercooler and get some intercooler hardpipes
it will make a big difference

Get a metal headgasket, it'll give you 50hp. Oh wait, I mean it'll give you piece of mind. IMO there is no such thing as safe hp with the stock headgasket from the factory.

word metal headgasket and arp head screws best thing to start with when trying to gain hp

Oops, forgot that I already have the 1.2mm HKS metal headgasket along with ARP studs. What kind of intercooler should I get? I saw some cheap ones on ebay. They were selling for about $90 dollars or so. What should I do?

unplug your wastegate actuator :)

No dont really do that, It will fry your turbo. Unless you have a car that is in terrible shape like me and it boost to 8 psi with the WG unplugged.

i've been hearing alot about metal head gaskets lately.. being new to the supra game (just bought an '87 7m-gte) i dont really know alot about them.. i went to toyota and they told me that the one they sell OEM is a metal head gasket.. is there a difference in those and any other metal ones ?

Where is the actuator? Is that SAFE????

idk about the dealer ship but i would go with hks or greddy. once i get my turbo engine i will be going to one of those two.

NO IT'S NOT

don't unplug it, if you are unsure where or what an actuator is you shouldn't be fiddling with it
