Boost!!!

[suprastroker88]

I have a 1986.5 supra. It was 7mge-T from the last owner but it was completely ghetto rigged. So I dropped in a 7mgte. It's all stock except a 3in downpipe, custom 3in exhaust, and hks ssq bov.

Can I turn up the boost to about 10psi or do I need to drop in more supporting mods first?

Fuel cut is generally around 12-13 PSI. You can run 10PSI safely on your motor, and youll feel quite a difference from the stock 7 or so.

I ran 12 PSI on a stock motor with a MHG/ARP's an exhaust system and intake.

I dont have one yet. I was planning on just picking up a cheap mbc for now but later on I want to get the GReddy Profec B Spec 2

I like the ApexI AVC-R much better but thats my opinion

i saw that one too. which one is easier to use?

 

[s383mmber1]

For you modifications, and for such low boost, a very effective and stout boost controller can be made for under 10 dollars.

I've never used the GReddy Profec B Spec 2 so I don't know. Can u control the boost individually in each gear with the B Spec???

I agree with going with a cheap controller for now as well

Dr jonez makes a good one....and your playing with fire without addressing the headgasket issues first before turning up the fun I mean boost

Yea I know. Im going to get aorund to that. The guy I got the car from gave me a GReddy 2mm headgasket. Brand new still in package. He paid like $320 for it. So Ill probably have that put on when I get the engine rebuilt. Im trying to wait to have it rebuilt because Im saving up so that when I get it rebuilt, I can go all forged internals

If you got a JDM motor I'd rebuild with out question!!!!

 

[tbcmorris]

Your going to make that rebuild come a lot faster if you turn up the boost on stock HG...at least retorgue the headbolts...

 

[MKIII TURBO60-1]

leave the boost alone unless u want a rebuild now lol, blown headgasket=no fun

i second that statement.... ive had bad experiences in the past. you will never be sure how solid your motor is until you have it rebuilt and you buy the parts that go in it.

Its not a JDM motor. Its a motor I picked off of a friend that was doing a 2j swap

So if the headgasket is still good, I can just have it retorqed for right now until i rebuild it?
