Re: engine conversion

i have zero idea why your posting this on a ford site, as opposed to somethign like, www.nissansilvia.com where this information is readily available, and alot of people on that site have completed the exact conversion your talking about.

so yes it can be done, depending on what you want to acheive would be as to why you woudl want to do it, the 6 can easily provide 300 rwkw whereas the sr20 with the same 300 rwkw wouldnt be driveable by any means on the street.

still... why ask on a ford site a blatent question about nissans ?

Re: engine conversion

scott: yes its not a too hard conversion. just yesterday i met up with a guy who has a rb20 in his 180sx, plenty of space to fit the rb engine and everything else you need (makes the sr look tiny). Since the rb25 is identical to the rb20 (physical size) i dont see a problem dropping it in, however i suggest some minor improvemnts, if you do the conversion.
get rid of the standard RB20/25 intake manifold and use a greddy log style setup, first better flow and design, second more bonnet clearance and third reduced intercooler piping, hence less lag.

otehr than that is quite easily doable as long as you use a front cut. wiring loom etc has to be all transferred, aslo i recommend using and aftermarket ecu, rather than the std unit (ie apexi).

cheers

Re: engine conversion

uese a vl bottom end and a skyline head works great as a combo and you get half a litre more capasity.

Re: engine conversion

note you cant use the rb20 head with the vl bottom end, unless you want custom pistons, also i heard one or two oil galleries need to be blocked with that combo

Re: engine conversion

It fits but very tight! Pusher fans are required due to clearance and clutch changes are virtually impossible without dropping the crossmember.

Its best to get a R32 crossmember and use that. The conversion I worked on used Mazda RX7 ser 4 engine mounts which are thiner and did not have bonnet clearance problems. The stock clutch blew up on the dyno and it was an absolute prick to change it out so be warned.

Re: engine conversion

if you want anything decient i would be getting good pistons anyway while you have it apart, do it at once instead of pulling it apart 5 times or so

Re: engine conversion

Notice that scottr33gtst hasn't typed back...

Maybe he wanted to know how to fit a BA gear knob into his conversion?
