Top RB20 Club... do you have over 260rwkw?

[Cubes]

Im bringing my car over the first wek of Feb, fingers crossed with a re-tune and new exhaust ill be pushing out close to 240-250rwkws:) Maybe we dont need the 300cc, but hopefully we dont have wild wheelspin either:)...and fingers crossed it lives and the old $600 RB20 provides plenty of fun:)

heheh.. Not directed at you Roy..

Considering you use your 32 for a lot of track work it does make me wonder if it really is worth building up a motor??? Would you get that much more life out of the rebuilt motor to warrant building it up over cheap second hands.

1 rebuilt motor is close to 5-6 second hand motors.

[Ahh32]

woo up there ice cube..

1. suggestions about my RB24 build.

i have some people to prove wrong.

if i still had my RB25de i would have built a 25/30 a long time ago.

i would love a 30 but i decided to go the 24 route because i just did.

5-6psi more boost will be overcome by higher CR

other than that a 20 sounds better.

DANGEROUS_DAVEO: i prefer beef wrapped in bacon

P.S. MMOOOOOOO

LOL...its part expense, its part value. The track is great fun whether you are doing 1:30s or 1:26s, so if i keep popping RB20s (I suspect from about Feb onwards all the tomm fullery/butchery will be fixed on my car), so not expecting any more problems.

If the engine croaks then ill at least be comfortable that i know the limits of the RB20...i have my thoughts but thats all they are:(

If you want to go genuinely quick the RB20 can do it. But the dollars dont add up and you have to seriously consider stepping up to a bigger RB. BUT... If you want heaps of fun, and not be living in fear of popping/overheating etc etc an RB26 then RB20s rock:)

Dont have to be the quickest, just wear the biggest smile:) So 6-8 grand to get 3-4 seconds quicker, then i think about how many track days 6grand buys me...lol have you seen Pumping Iron where Arnies talks about lifting weights every day is like cumming...well 6 grand is a sh1t load of track days and i suspect it would have a similar effect on me:)

Im in SA for the next 3 weeks, so bring on Mallala:)

[Cubes]

hehe sorry ahh32.

update; ADPSI made 480rwhp - 30psi on Pump with a mix of tolune.

[Roy]

Cool...go the RB20:) Whats a built motor?

Well said there Roy !!

never really looked at it that way but it makes alot of sense.

with RB20s being cheap there is a big gap between rebuilding and a second hand motor costs.

If we were talking RB26, its a shit load more expensive.

Thing is you could theorectically push the stock bottom end pretty far. I think a few of you guys are accepting that they blow up when making a certin power output. I think with a decent tune, you would make the same power but have the engines last a fair bit longer. And well $600 isnt much compaired to a full proper rebuild, but its still a fair wack of money and a fair bit of time wasted changing over the bottom ends.

Exact thing a mate had problems with, bad tune, didnt change anything but pulled out 2deg of timing and the thing never blew up, same power tho.

[nod]

I'M CONVERTING A RB20 INTO A HOLDEN VL COMMODORE AND IN DEARCH FOR A WIRING DIAGRAM!!!! THE ONLY PROBLEM IS THAT THEY COST IN EXCESS OF $500

IF ANY ONE HAS ONE PLZ CONTACT ME:: [email protected]

I do not know of a single RB20 with around 240-250rwkws that gets driven on street and track...but i agree about the strength of the RB20,

I suppose this year will be the litmus test, though when the mechanic installed the new engine they didnt throw a new timing belt on the car, and there seems to be some idler bearing noise so may change them too...hate to lose an engine because a mishap up front with ancillaries:(

[Ahh32]

Unfortunately i don't live within 900kms of a race track, so if something does go bang at the track, it is long way to push my car back home.

My motor was fully rebuilt (std)a few months ago. but my dad put a bit of it together, due to my work commitments. anywho, he didn't check the ring gap cause he thought i did, and i hadn't yet. so the end result is low compression in all, and oil in number 1. hence why i want to do it properly this time.

My new list of parts are: Tomei 82mm pistons

Tomei 1mm head gasket

Tomei cam gears X2

HKS GTRs kit

other stuff: Bore engine

new exhaust gasket

gates timing belt

ECU remap

New rear tyres

ROY: idler bearings are $120 for idler $160 for tensioner i think from memory

[LUMPY]

We have done several (in S13's!) just over the 310hp@wheels mark with LUMPYROM on board.

[Roy]

Im hoping to get near 340hp, tuend many around that figure? Do they run brearings, throw rods, drop pistons or do they just get tired and start to get a bit of blow by not knock out the performance they once did?

[Bl4cK32]

ROY: idler bearings are $120 for idler $160 for tensioner i think from memory

$80 each for two tensioner bearings

$37.50 for a timing belt

when u have the rb30det.....sorry had to throw that in

update; ADPSI made 480rwhp - 30psi on Pump with a mix of tolune.

and what turbo is thihe using?

[RNS11Z]

its turbo i believe, t66/7. Not exactly sure. Built motor such as pistons rods bearings cams plenum ecu inj pump and other little things.

Roy: from the ones i have seen they just get tired after 300rwhp. Blow starts to occur then knocking then you know finish time. A friend had one with over 300rwhp and standard ecu but with a plug in chip, thrashed 24/7 for a good yr then got tired and blow by then knocking then finished.

[Ahh32]

does anyone know of a good ecu chip remapper dude in QLD

[Cubes]

RB20DET... Not bad for a 12-16 year old motor.

[Skyrine-Dave]

a mates mate has an R32 and his RB20 has put out 480hp on the dyno... with 30psi and tolulene... but was prolly C16.

thats some bullshit power... i didnt believe it but apparently its spun up 400+hp on a few dyno's so i just dont know.
