Truck Turbo On Rb30e

[GT-RZ]

I have aquired a free oil cooled Garret turbo!!! of a truck... the size looks fairly good with a 3" front and rear mouth and:

Front A/R 50 - M24 B.O 4

Rear A/R 81 - M1 L.G 2

problems apart from the fact i'll have to make custom flanges to fit it. There is no waste gate internally and no opening to fit an external gate either. Anyone have any solutions apart from not use it... i don't want it to continually increase boost and then pop my engine...

You'll ned to make an attachment for a wastegate. Either on the manifold, or butcher it right onto the turbine housing of the turbo itself.

i suspect your free turbo is going to cost a lot by the time you finish modifying it, fitting it and then getting disappointed with the poor response from it.

As long as you vent after all the collectors have merged you'll have no problems

Ive seen some adaptor plates that are sandwiched b/n the exhaust manifold and the turbo itself. They are pretty much a hollow billet with a fitting coming out at 90deg to allow for ext. wg

Hahaha, this should be good. Let us know how it goes

[paulr33]

sell it on ebay or throw it out

its junk - why do you think you got it for free

Before you listen to all the haters...

What is the application you are planning to use it in?

If you are putting it on a street car, dont. Response is important, youll be spending money elsewhere which would be better spent on an actual decent turbo, so on and so forth.

However, if you are throwing it in a track basher for a bit of fun, I say go absolutely nuts with it

Dont be dumb and spend lots of money doing it though, make it proper ghetto. Do the welding yourself, no management or anything sophisticated like that

Draw thru webber ftw

it's for a cheap as chips r31... i will be doing the extra plates for a vl manifold or maybe a cheap one with an ext gate flange i don't know.

i thought the size of the turbo would be responsive enough for a 3 litre. will be running on a vl turbo ecu and no extra management. does anyone know the comp ratio for a standard rb30e?

i might infact simply weld the turbo to the manifold to save custom flanges...
