ITRCA

i just bought a 01 type r from a hole in the wall dealership. i checked everything out but what i noticed later on was that i currently have a GSR head with a skunk2 manifold. i cant tell what kind of cams i have and also. the car runs strong.and when i did a compression check on it. all 4 cylinders are shooting out 225 psi. i tried doing a search but i cant get my answers...

basically i heard its good for people to use the other way around. which is a gsr block with a type r head. so my question is: how good is this motor? is this faster than a stock type r? and where should be my redline at? i cant tell whats in this motor.

i currently added:
-jdm apexi headers with 2.5 flange.
-spoon test pipe
-apexi n1 exhaust
-real spoon ecu with harness
-spoon drop in filter

this has been stressing me since i realized i was using a p72-2 head.

please help.. thanks

The question really is what valvesprings and cams do you have in the car. The redline will be determined by valvesprings. The head flows great and with a skunk2 manifold you shoudl be fine. This isn't the perfect setup but it could be worse.

To my knowledge, the only way to find out what valve springs you have is to pull them off & measure spring tension & height. Trey's right...you shouldn't have any problems, but I'd be concerned about the install job.

I think it would be worth my time to find out who the previous owner was & get the skinny.

actually the GSR head will give you a bit more compression than the ITR head just worry about cams and valve springs

is it still using a ITR ECU?

Who would do that to an R?

yes its still using an itr ecu. gosh this is so nerve racking.
