Nissan GT-R Turbos R32 , R33, R34, R35

The following is some information on the stock and aftermarket turbos available for the Nissan Skyline GT-R , and Nissan GT-R. R32, R33, R34, R35 as they are often referred, being the chassis codes.  

 

 

 

 

R32, R33, R34

Above about 1.1 bar the stock RB26 turbos have a tendency to break the exhaust wheel off. People have gone low 12's, high 11's on the stock turbos, but not for long. Stock peak boost R32 is about 0.8 , R33 0.9, R34 1.0.

Stock exhaust manifold on the left, ported, modified N1 manifold on the right

The exhaust manifold on the left side of the picture is a stock R32,R33, R34 piece. On the right is a modified N1 exhaust manifold from a Nismo built Super Taikyu car. You can see bracing between the manifold flanges, and the larger hole for the turbo “foot”.

		Standard	Spec V	HKS-TF
COMP	Trim	60T	60T	64T
	IN（mm）	43.4	46.5	46.5
	OUT（mm）	56	60	60
	Number of blades	12	12	12

	IN（mm）	53	53	53
	OUT（mm）	39.8	48	39.8
	Number of blades	9	11	9 + cutback

edit-I am not sure this is the standard GT-R turbo, it specs out more like the SpecV turbocharger

Uses an IHI turbo, with an integrated exhaust manifold.

IHI RHF55 same as MY06 STi Impreza
