Hey guys in the market for an R32 and have found a mint one, but just wondering about the RB20 silvertop.. is this the stock engine for the series? Car is 1989 R32, with an RB20 silvertop obviously. Is the silvertop any different from the other R32 engines? And if so does it have potential... with a realistic budget ofcourse.

Cheers.

No that isn't the stock motor only later model 32 gtst's had the silver top NICS Rb20, it is a good thing though as it is better than the red top ECCS Rb20 which is the stock motor for the car. The silver top has bb turbo and rated at a bit more power.

As for potential Rb20s are good for stage 1 mods like exhaust, bit of boost, ECU, gives about 160-170rwkw.

Turbo, intercooler, fuel pump, AFM, injectors gives 200+kw but they lack torque and people usually dont bother and dump them for rb25s

hey mate,

from what i know..

the rb20 has been around for quite a while now. started out inthe r31 in japan as an rb20 redtop NICS. then, after some development, along came the rb20 redtop ECCS version, also in the R31

the r32 came out with the rb20 silvertop ECCS version. all r32's have the rb20 silvertop version, all have a ball-bearing ceramic turbo, all are intercooled etc.

they are a great engine for modifications. now remember that they are only 2L in capacity, so when the turbo is "off boost" they lack the ability to get the car moving like a commodore would. but, after say 3000rpm, they really get moving.

on a manual car, with about 2000 spent on an exhaust, boost controller, and maybe a front-mount intercooler, they go like a cut snake.

Nope all r32's rb20's were the silver top. R31's had red tops. NICS were the old red tops, ECCS the silver top.

WTF are U jabbering on about? ALL R32 GTS[t/4]s came out with a silver top (RB20 ECCS).

Hmmm yeah that would be cool bubba.. going to have a squiz at the car tommorrow arvo.

Well i'm not so worried about all about power... the car seems to have ALOT done to it.. what i'm worried about is that he told me it has 'alot of lag'... it has a Garrett T-04 turbo fitted to it... I'm concerned about a mismatched turbo... full boost isn't until 4500 so i'm told..

Anyone know of this turbo being fitted to an RB20?

Cheers.

sounds pretty big.. i get 13psi through my stock 20 turbo by 3500rpm, stock is reasonably laggy as it is.. taking gaps in traffic is chewing my tyres :no:

is the engine stock internally? coz the turbo would probably go well on a 25 when the 20 dies :P

Yeah its stock internally...

but add ons.. has secondary injectors, Greddy rebic fuel computer, HKS ext wastegate, aft manifold, 3 inch turbo back exst, FMIC, GTR fuel pump, EBC, remapped ECU..

Could be a hard one to keep on the road i'm thinking..

Sounds fun! the turbo/manifold/gate should bolt easily onto a 25 and the supporting mods such as exhaust/fmic/fuelpump/ebc are done so all you would need is an RB25/ecu and it would be even MORE fun! Oh and maybe some injectors depending on how hard you want to lean on it :)

      Yeah its bad eh. Ey! Watch your mouth. Yep, spot on. The rear's are always gone too though from brake checking. I had them perilously close to a tree that we had taken down. I think the tree peeps may have taken it. Either for a trophy, or accidentally.

      f**kin' yikes! That insulation is the shittest stuff I have ever seen. You need to do an insurance job on that f**ker, pronto. WRT to the washer cover, I would have said that there'd have to be some at a wrecker, then remembered that it's a BMW, and reasoned that every single wrecked one would have been tailgating and so the front end would be trashed.

      Ok, so I got myself some X1 wheels really cheap to try out, they're a bit different and I like them but they're really narrow (18x8) they are available in staggered 18x8/9 also but really hard to find.  I kinda dig them, but not as much as the F10 19's I usually run, so these go into the wheel pile.         As I mentioned in another thread, I got a new exhaust. It's an off-the-shelf stainless one that fits OH-KAY. I don't love the tips size and how far they come out the back, I think I might cut the tips off and replace with some smaller (~3") ones that don't extend as far. It sounds really good though, I'm not sure if its just in my head but the car feels a little quicker, more responsive.      I fitted an eBay special front lip. Surprisingly it fit perfectly and all holes lined up. Its a little rickety but I haven't put any double sided tape on yet, I want to clean the front bar up where it has scraped the road a lot and fil in the number plate holes (or, get body coloured wrap to cover them - is this a thing?  I'm not sure if I'll leave it gloss or pain it matte. I really like it though, I don't particularly like the front bar without it, I don't really like the M-Sport and to get anything else is just too expensive. That said, I might need a new one now anyway as I dropped the car onto the jack after forgetting to put ramps under the front wheels. It bent a lot and while it did go back to normal after I got the car off the jack, I do fear I have not done it any favours.    Lastly, my headlights died. Different problems in each. They have gotten much dimmer over the past year or so, I put new (uber expensive) OSRAM bulbs in them but to no avail. One of them pointed at the ground and the other just kinda did its own thing with light working sometimes. Yeah, check this 18 year old BMW headlight wire. I reckon I know why they were stuffed.            BTW, the yellow and black is the power to the Xenons. Yikes. I hunted around an researched my options here. I would have loved to just get a replacement harness but not a thing. My car has adaptive headlights, that is they rotate left and right with the steering wheel. Good condition used adaptive xenons were over $700 each, non adaptive were around $400 each, but I couldn't help but think that they're all around 18 years old now, surely they'd have the same problems. So I looked at newer LCI headlights but they were even more expensive and I couldn't confirm that they'd be plug and play with lots of people having lots of opinions so not worth the risk.  I ended up getting brand new Chinese headlights from MARS. They're very close to OEM with only the angel eyes being a bit different. I didnt want crazy turn signals or sharp DRL's or anything. Not my bag.  They're not adaptive, I thought thats a feature I wouldn't really miss. So I coded that out.  The lights are awesome, they look so nice and they take so many years off the car. The angel eyes look great and the headlight brightness is ridiculous. I was so used to the old ones, I didn't realise just how bad they were. The new ones use the OEM bulbs, Xenon ballast and leveller motor which I was happier with. The only issue with them is that the rear cover is held on by SEVEN screws. This will be a nightmare to get to and open when I need to change bulbs.

      Lets play a game - What is causing my oil consumption?

      Now that you mention it I can see those too. More subtle. The lighting and low resolution makes it hard to assess super well what's going on but what is visible is bad enough to pull the motor.
