26/30 Into Gtst

[waxracing]

I know the grt guys have clearance issues with the rb30 into the gtr with the spacer etc.

How does the rb30/26 go in the gtst r32 . Is there a clearance issue at all

[rob82]

I spaced the whole subframe down 12mm and cut two slots in the bonnent and it fit fine.

was that using a 26 intake ??

I was trying to avoid spacing the subframe down so as not to effect my roll centre

I can't see how you would fit a 26/30 combo into an r32 of any kind unless you used an rb26 style front-facing plenum (or why you'd want to run anything but the front-facing plenum).

With the GTRs, the main issue that affects the engine mounts is having enough clearance between the big alloy sump and the power steering lines.

I imagine that in rear wheel drive configuration, the fact that your sump is a bit of tin could make it possible to mod the sump to allow more X-member clearance, and mod the mounts to drop the motor.

In terms of the timing belt cover clearance issue, apparently there is some way of fitting the rb25 cam covers and timing belt cover to the rb26 head etc, that gives more clearance.

Once that's done, there's the issue of the twin turbo turbo collector pipe. I got a bit of clearance by grinding off the alloy mounting boss, but still needed to run 20mm spacers in my bonnet hinges.

Yes - but I never put the cam covers back on.

26/30 fitted straight into my r32 gtst just needed to trim bonnet,I have a pre trimmed fibreglass bonnet for sale if you want it.

Thanks but i have a gtr bonnet already. Im going to look at running fd mazda rx7 mounts as they lower the engine

or just custom make the mounts so the sump is as low as it can sit on the steering colum then work out if you still need to cut the bonnet.

my Rb2630 went into the s14 with no bonnet/ hinges mods. it has a dry sump on it and the sump is 4mm off hitting the steering colum,

and we had to solid mount the motor to ensure no twisting..

Just use the R32GTSt (RB20DET) engine mounts and redrill the holes lower as per the pdf guide, that should get rid of most of the clearance issues and all that might need attention is the "twinturbo" pipe.
