Eoi. Supercharger Kit For Rb Twincam Motors

[R34 -_-]

I'd be keen to supercharge my skyline, but id do it properly with an aftermarket supercharger.

What i want to know is, bang for buck what puts out more power: n/a + Turbo or n/a + supercharger??? (on a minimal budget)

[mad082]

that is like asking how long is a piece of string. unless you can give turbo and supercharger sizes it is a pointless question,

if the engine was a rb25 and it was NA + stock turbo or NA + toyota supercharger then i would have to say that the turbo will shit all over it. the toyota supercharger is miles too small to effectively provide enough boost in the top end of a 2.5L. even on a 2L it would struggle. you have to remember that the superchargers are generally for toyota's 1.6L engines.

i know people who have put them on commodores before and while they do make a difference it does trail off a bit up top. the commodore motors are a bigger motor, but they don't rev as high as the rb motors so it sort of balances out a bit and brings them closer as far as the volume of air they use

I was meaning an aftermarket supercharger coz i know toyota ones are shit, but i don't have much to spend so id say about $2k is my budget. Also n/a plus T = shit power you only get like 180kw which is like a stock r33 gtst.

When did Stock r33 GTSt's make 180kw? Mate take a 180rwkw NA+t against a 180rwkw DET and the +t will leave it miles behind.

Gee... I must have only picked up 5KW with all the mods done on my R33 GTS-t then...

FMIC, full 3" TBE, lightweight flywheel, CAI setup... 185KW (That was a "roller coaster" setup though of a power curve... Once tuned 193RWKW...

DE+twill be more tractable power wise off boost too due to higher compresion.

[DRD-00F]

meh, my 33 GTST made 178rwkw with nothing but a frount mount... It was running quite a lot of boost though...

added an ecu, full exhaust, pod filter and gained like 12 kws...

Now it's over 200 with all that shit, but the turbo is pushing out a bar of boost or more...

Every car is different.

don't waste your time with a supercharger, especially if you have a 'minimal budget'. Modifying performance cars has nothing to do with minimal budgets...

Bickering aside, a blown RB2630 would be a weapon in just about any situation it finds itself in.

Or, get an alloy V8 in there, then supercharge that. Winner.

firstly, 180kw is a hell of a jump over a stock NA. it is roughly a 60kw jump. what do you think is the reason why a NA+t using stock turbo etc won't make more power than a DET? and what makes you think that just bolting a supercharger on will be better? the reasons why a NA+t will only make as much power as a DET will be the same reasons why you won't get much of a different result with a supercharger install with a budget of 2k. do a NA+t and spend about 5k on the job and it will make a lot more than 180kw, as would a supercharger upgrade at the same money

When did Stock r33 GTSt's make 180kw? Mate take a 180rwkw NA+t against a 180rwkw DET and the +t will leave it miles behind.

not entirely true. if you have both cars crawl along at about 1500rpm and then floor it the NA will pull away, but if both cars are at around 3000rpm or a bit higher when you floor it the NA will pull away a fraction (doubt it would even be half a car length) as the NA will spool up the turbo quicker then they will both accelerate about the same. at the end of the day 180kw is 180kw. the NA will have more down low but up top they will both go the same. the only other thing that may make a difference is the gear/diff ratios. which ever ones has the shortest ratios will have the quicker acceleration, but will have to change gears sooner.

[Madaz]

^^ CORRECT

na have 4.3:1 ratio while det have 4.1:1

[mad082]

yeah i thought there was a difference in gearing but wasn't sure which had the shorter gearing

lol.

dont compare the kw, compare the torque & response difference.

eg: i made 180 on 10psi but torque was around 499nM

comparing with other 180rwkw RB25DETs around they were getting 400~ nM of torque and were probably running bit more boost as well

Furthermore to dori's post... you can make alot more then just 180kw..... but you must have the MONEY/time/motivation/know how and tuner...

[na beast]

if this is the dude in newcastle im thinking about that reckons he's strapped a supercharger from a toyota on a n/a skyline it run's like a f**king piece of shit and the bloke is f**king full of shit, and yer apprently he put something like this thread up on "SAU" which im assuming this is it so yer

[dori34]
