hello all,

we're trying to fit an rb30 into an s14 which was previously fitted with an rb20.

rb30 block is using an r32 rb25 head and all of the rb20 accessories.

engine in the car it appears to be sitting proud of the fenders by a good inch or so (or i assume the extra 40ish mm due to the block hight increase).

using an r32 gts-t xmember and mounts.

rb30 oil pan appears to be close to fouling on the swaybar.

any ideas on how to get it to fit without putting a cowl on the hood?

search is a bit slim on this topic.

Mate of myn modified the swaybar to go around the front of the sump, then slotted the mounts to lower it down.

Can get more info off him if needed.

Selby's make a RB swap into S13 swaybar, im about to order one for our race car. (ive used notched sumps of late)

Slot the mounts on the engine (up) and slot the xmember (down) this should give you a full inch.

You will need a fwd facing plenum to do it properly (ie legal clearances) though.

im gunna be using ford cortina engine mounts to put my rb30det into a 180sx.motor isnt in yet,so unsure how much lower it will sit using those

Can you do me a favor and measure how thick they are?

I'm kinda confused guys... Slotting alone wont do anything to where the engine sits will it? You have to use other mounts AND slot for it to sit lower, no?

      Checked with amayama and nope, the full S2 manual set is not available anymore. Unsurprising, but still disappointing as the ? on availability gave a glimmer of hope.

      I've heard the Tomei USA head gaskets are decent if you want to o-ring the heads but otherwise not recommended.

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.

      Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.
