looking at a 180 that ive found and they have upgraded the engine which was a non turbo sr20 to a rb20 from a r32.

Is the RB20 a better engine than the SR2 DET or would i be better of buying a 180 with a stock turbo engine already in it?

any help appreciated.

does it still have LSD like the factory turbo cars. It would have to be 94+ model eh? if its got lsd then id get it especially if it has the updated interior. If you wanna go all out on mods then the rb20 is a more solid platform. If youre gunna go smallish mods id probably just get one with an sr20det. Also check how big the brakes are, i'd definatly want some decent stoppers on a car like that. If theyre the same size as the sr20de sils id be budgeting in a brake upgrade.

in the end its up to you. i'd try and use the fact that it was once an n/a, and your going to have to spend more on this one to spec it up, than to buy a normal sr20det one

Hey Steve its dropping oil already :mad:

CS_180: All 180sx were turbo I believe, except some of the later (late96, 97+) models..

RB20DET and SR20DET are similar strength/outputwise, you wouldn't replace one with another (:P)

Just consider that it will likely need as Gary said, brakes, diff, (maybe gearbox) and engineering!

Saying the SR cant handle the mods like an RB20 is a fairly broad statement which really doesnt hold any weight. The SR is just as good as the RB20 if not better, when theres Perth workshops turning out 700hp SR20 monsters then it makes you realise how good they are for a 2 litre, 4 cylinder.

And as meggala shows, putting one in a skyline results in enough engine bay room to mount an intercooler flat in front of the motor, which alot of jap guys have done in R32's. The SR is ALOT lighter than the RB20 (alloy vs iron), that picture alone should demonstrate that.

      Need AC Compressor for R32

      Out of curiosity, what's the reason for converting? I think @R3N3 might have the Frenchy's kit in the R33? I somehow think of you as the ambassador for realistic and clean street-driven setups nowadays

      careful when running the car after a boil over. Ive heard you can lose enough coolant that it won't show the right temps because of too much air in the system (or something like that). Make sure the levels are good before trying again.  Maybe a mobile mechanic can come have a look with their scan tool ?

      OK, just for some extra clarity - there is more than one option at Frenchy's. 1. You can buy the whole kit - with or without the actual compressor. The whole kit includes mounts, hoses, condensor, etc. That's either ~$2200 or ~$2800. No surgery required with this option. 2. You can buy just the bracket (~$600), or the bracket with the compressor (~$1200). Either of this or the above option "without the compressor" is if you already have an Echo comp or you are able to source one locally. Whatever the case, in this option, you will need surgery done on your hoses to adapt to the new compressor. When I said "the Frenchy's kit", I meant the whole kit in option 1. It is obviously somewhat more $$ than a $1500 OEM compressor. But if I had to spend $1500 on an OEM compressor, I would certainly consider spending double that to renew and significantly update everything forward of the firewall. Another option is to rebuild your original compressor. My R34 comp is currently dead and I will be most likely doing that to it if the spare one in the shed is also leaky.

      V35 Overheat + Coolant Boil & Overflow + Engine not Starting

      By carnoobb · Posted

      Hey all, my 2004 Nissan Skyline 350GT overheated the other day with coolant boiling and leaking out of the coolant reservoir when I was parking. So today, I started it up again just to see if it was a thermostat/head gasket issue. After about 20 mins of running, temps were normal again, no coolant was leaking out and the upper reservoir hose was warm but my engine suddenly cut off. I checked the oil dipstick and cap when it was running and there was no white foamy residue and the exhaust did not have white smoke. I tried starting up the car again but it would only crank, similar to when I had a camshaft sensor issue just that now there’s no check engine light on the dash. Any ideas? Unfortunately I don’t have an OBD2 that can read the Nissan's programme.
