I have an SR20 in my cefiro.

Use a silvia front crossmember.

Radiator will need to be from an S13/180sx or you can use an RB series radiator if you extend the top radiator hose to the other side.

have read that some combination of gearbox crossmember will fit but I couldn't figure it out, just modified my current one.

Can't remember exactly about the tailshaft, I think if you unbolt them at the center bearing and swap the front half over it works.

heater lines are just rubber hose, you can easily make it fit.

Needs a few wiring modifications but I didn't do the work so can't tell you there.

I would definitely do this conversion again to R32/cefiro/laurel, the RB20 just doesn't compare.

sounds good dude thanks very much...about the front cross member i taught sr20 drop straight into skylines so would it not drop straight onto the cefiro mounts?also the the 2 little pin type mounts on the end off the sr rad,do they sit into the original cefiro holes on the support legs?A manual cefior mount is the same as an s13 so it should work on the same mount if you have a manual cefiro which i do?

My understanding was that the SR conversion requires the crossmember from a silvia even if it is going into a skyline. Perhaps you can use custom mounts or something otherwise.

Cefiro's are funny with gearbox mounts. I used an S13 manual gbox crossmember to convert my originally auto RB20 to manual, but the same crossmember didn't work so well with the SR conversion. If your cefiro is factory manual then the case may be different.

    • Have a vb in honour of the car comming back
    • It was a great, but typical track day, and some VB was ingested at the night time debrief 🤪
    • And so, to round this out, I couldn't be happier to confirm @MBS206 has decided to buy the car. He drove down from sunny QLD with a trailer last week and it is off to its new home today. I'll let Matt confirm on next steps but I understand broadly that the plan is to leave it pretty much as is, and just get some quality wheel time with a nicely balanced car that is pretty much track ready. There are a few a jobs still to be done first but nothing too major and I think its a very smart buy Dinner last night at the Paragon with a round of VBs (mostly) for Neil
    • Well, 50 pages and the end of a chapter for this car. We took it out for a shakedown at Wakie yesterday, and everything went well. There were a couple of niggles: - Oil cooler fitting leak - tightened, cleaned, stopped leaking - Radiator cap overflow fitting was leaking....Mark called it, the overflow fitting was threaded in and not tight....tightened, tested and held pressure - Small oil leak at the rear of the block, probably the turbo oil feed - too hot to get at it comfortably but probably just needs to be nipped up - leak at the driver's side rear brake line where it meets the hardline. Fitting wasn't loose, so Matt backed it off and back on, no further leaks - there's also a leak somewhere on the top of the fuel tank, maybe that cross over fuel line - that was has been left to fix when its on a hoist Otherwise than those niggles the car went great, turned great and stopped great so it was a very successful day out. I'm always really nervous when a car first hits the track after a long break, especially with a brand new engine as well but it was great. VID-20251011-WA0007.mp4  Big thanks to @The Bogan who dropped by and helped out, @MBS206 and my nephew Lachlan the apprentice.  Neil's wife Mel also surprised the hell out of all of us by dropping by; she's up in Tamworth these days but was travelling to Melbourne so had plausible deniability for turning up at the garage, it was great to see her but also obviously a bit sad all round.
