I am going to be purchasing a spark racing race version manifold next week and would like to order the turbo ahead of time so I have both ready at once. The manifold is constructed of forged stainless and incorporates a T4 flange.
My question is would this manifold work with either the Garrett GT25/40R turbo, the Garrett GT3071R, or the Garrett GT30R? I don't want to buy the turbo and see that it isn't compatible with the manifold. If anyone can let me know, please do.

 

You should call the place that you are getting the turbo from and inquire to the turbine size of your turbo that you are interested in. Ask them if its a t3 or t4 turbine house. I believe the garret GT35R and the GT30R are t4 turbine houses and should bolt up to the t4 flange but call to make sure.

 

i don't think I will buy from the place I was going to. They don't seem to ever pick up my calls, and never return emails.

New Question, i guess the only garrett turbos that would fit are those that come with t4 flange. Am I correct? If so then which garrett turboes have the option of a t4 flange? i have heard some have the option between t3/t4 flanges, but do not know which ones. Any from my list have this option? Thankx in advance.

 

wow no one huh? I guess I have to try harder to find out the answer for myself then.

 

Surely your first port of call would be the manifold manufacturer followed by the turbo shop.

It's not just the flange you have to consider but the space available where the turbo mounts. If it's beside the engine soace is tight. If it's infront there is a lot more room.

 

You should try asking this question in the Under The Hood section.

 

Yes it does mount in front, It is similar to the CJB80 manifold

 

I have a GT30R (or 3037- same as a HKS 3037). The turbine housing is compatable with T3 flanges, NOT T4 flanges. The GT35R does run a T4 turbine housing.
