Dump Pipes 1G-GTE
 

Hey ppls hows things,

Id like to say thanks to every 1 who helped on my boost leak thread that is all sorted out now... the dyno was @ 144rkw and when i fixed the 4 boost leaks i felt the benefits from the beginning!

The car is now making a healthy 150+ rear kw and my next plan is to free up the exhaust gases at the dump pipes on the lil 1-G mill.

The Stock Dump pipes are sort of Y shaped to accomodate the twin turbo setup and i can only see restrictions in this stock setup.

My question is there any where in Japan or Here is Oz who distributes after market Dump pipes for my 1-GGTE motor?? I have skills to make my own but ill try to investigate the bolt on items first. Im expecting at least 25kw from better dump pipes which i believe is resonable.

Cheers

Frank

hmmmmm i don't think you'll find any... you may have to make your own

god damn, what you making 150rwkw with? what boost... what mods?

another major restriction i see in the stock twins setup is the intake piping... what about separating the turbos and turning one around.. and altering the intake piping

just an idea :)

problem with trying to turn the turbo's would be where they bolt to the common manifold. below is a pic of the setup on my dads 1jz, different to the 1g setup, i know, but could give you ideas on what to do with yours.

Thanks for the ideas!
 

I may need to make a new turbo manifold so i can get more room. Looks like there isnt even enough room on the supra to even have 2 separate 2" pipes ;-X.. who knows. Yes, positioning the turbos higher in the engine will give me room. Ill have to research it...

The car dynoed at 144rwkw but that reading was with 4 boost leaks - 1 on my HKS BoV (that i fixed by dissconecting a connectyor pipe in the BOV)... 2 on my new FMIC piping (wasnt a bad job for a first time FMIC done all on my own) and 1 on the inlet. Boost was at 12psi.

Now i fixed all that the mill runs 15psi no dramas, doesnt hit fuel cut and is very drivable for an easy ride, and feels A LOT quiker and smoother.

Mods are all bolt on.

fuel cut
 

hi to all, i have a 1988 supra with the 1ggte engine, recently i installed a manual boost controller. i have also install a bov, however i am puzzled by the fact that once the car passes stock boost levels it gives me a fuel cut, if i keep flooring it, it would continue to cut for about 3 times before the car really goes and hits the 14 psi, can anyone tell me whats causing this cut please. thanks
