I am looking for some pics of the HKS lowmount cast manifold fitted on an RB20/25 motor. I can't seem to find any. I want to see how tight it fits with a larger T4 turbo. I am mainly looking at the compressor clearance. Google's search came up with nothing and even searching for HKS Manifold gave me 100's of pages with no pictures.

I have a Turbonetics T66 mounted on an RB26 cast manifold and it clears easily. Having compared the RB20/25 manifold with the RB26 manifold the only difference is the bolt pattern to the cylinder head. :rofl:

Well I have a T3/T4 with an E compressor cover. The HKS manifold I have is already studed for a T3 flange. I was hoping to be able to make my own mounting holes so I could angle it a bit if need to clear my steering shaft (Dam LHD cars) From what I have heard from others who are using the manifold in there S13/S14's is that you can't use the larger S compressor housing because it hits the motor mount. Right now I am using an adaptor box with an external wastegate plumed into it.

Sorry, we're right hand drive downunder same as Japan.  My turbo is nowhere near the engine mount though.  We can buy T3 to T4 adaptors off the shelf, no need to make one.:rofl:

This is what I had made to fit the turbo to my stock manifold. I look at it as a poor flow design so that's why I want to go with the HKS manifold setup. It also forces the DP to make a sharp bend to clear the steering shaft.

Hi

I have the hks manifold on my rb20 with a hks to3 on it and a hks 35mm external waste gate and found i had to modify the engine mount heat sheild so the compressor air intake was clear the pic's are to large to upload though so i cant show you

cheers peter
