What modifications would needed to be done for a RB26 conversion into an 180sx?

Also, how much money would it cost? I know that an RB26DETT r32 from JustJaps is $6500(give or take a few hundred), is there any other costs i should consider keeping in mind that i can do most of the minor adjustments myself.

Also, added to this engine conversion, is it possible to turn this 180sx RWD into a GTR AWD? Again, what would is needed to be done to make this happen?

thanks in advance.

Engine mounts, R33 GTSt gearbox (identical internally to R33 GT-R gearboxes less the front transfer case for AWD), radiator (stock 180SX radiators won't cope with an RB26), ECU, brake upgrade (to atleast R33 GTSt spec), new intercooler piping, new front pipes for exhaust made up, and getting the whole thing engineered + roadworthied.

No you can't turn the 180SX into AWD, well, not without truckloads of money

It's cheaper to dump an RB20 or RB25 (or some hybrid of those two) into the 180SX.

Also, why ditch the stock CA18 (89-91) and SR20 (91-97) engines anyway? They're great engines with heaps of potential (except the CA18's are getting a bit old now..)

I assume the halfcut would come with wiring, ecu, intercooler, radiator, but most don't come with brakes.

halfcut ($6500)

r32 crossmember ($150-250)

modified sump ($300-500)

r33 gtst gearbox ($1200-1500)

flywheel and clutch ($500-1000)

machine speedo drive sensor ($?)

custom tailshaft ($500)

brake upgrade ($600-2000)

intercooler piping ($400-800)

exhaust ($400-1000)

fuel pump ($200-400)

mating wiring looms ($350)

Labour ($0-3000)

So you're looking at about 11k bare minimum to 16k for good clutch, s/s exhaust and i/c piping and labour. Zoom did the conversion themselves and it cost them 11.5k.

Umm I've seen an RB25DET NEO for sale on this forum for 3000. Whole package apart from loom, which is like 350 max from wreckers.

I've seen an SR20DET including everything for 1400 on a forum. You could just buy an RB25DET and find someone who knows how to do the job and get mates rates. If not see the quote on RB25DET into 180SX. RB20 is not worth it.

<180sx purist>Why do this? The SR20DET is capable of assloads of power if you want, especially with the cost of a RB26 conversion. With some internal mods, you could pull over 500rwkw from it. See Theo's S15 drag car - does 9's with an S13 SR20DET. And I saw 2 180's at Autosalon doing 333rwkw, one with just a HKS 3030something turbo and FMIC (not that it would last every day at that boost). Besides, the added weight of the RB26 will wreck the balance of the car, and overall make it heavier (thus requiring more power). < /180sx purist>

But if you want to do it, do it. It will be interesting! :cheers:

      What brakes on R34 GTT(Europe)

      Pads for R32 GTS-t, R32 GT-R non V-Spec (Sumitomo), R33 GTS-t and R34 GT-t are all interchangeable. R34 GT uses a 2x piston caliper, hence it didn't fit.

      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)

      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.
