Supercharging R34 Skyline

[The Mundi]

thanks dude. much appreciated. in the end i have researched my butt off to make sure im doing the right thing! and i know i am...sure its 30k but i know its gonna be worth it in the end lol im happy with my decision.

Well, stroking a 2.5 to a 2.7 is going to adversely effect you compression ratio and make the engine more prone to detonation, you need to shift a huge amount of air for 500kw, the two of these add up to disaster. But I think the sc and engine will run out of huff long before then.

op, here ya go...

op, here ya go...

lolz na man she wants to do something unique like blow her car; thats different!

jokes aside, i like the charged route...check out the s15 twincharged which is really cool (i know its turbocharged too) but in the US they are selling quite a few supercharger kits for bmw 3 series with great results! aim for a reasonable amount of power like 400ish hp from an efficient supercharger and you can have a torque monster

The bmw kit is stealth; anodised black it just blends in with the engine covers so it can be made 'stealthy' im a big fan

While on the topic of supercharging RBs here's a good example into a Silvia.

S15.3 Supercharged RB30

Well now that I've read this from start to finish I'll comment:

To ahjosh - your a knob.

To the 34 girl - I think you may need to rethink the numbers, I know you say you have done "alot" of research and Im not doubting that. What I am doubting is the ability of a stroked 2.5L engine being able to produce 750Hp with a supercharger.

Regardless of what you do during this rebuild it simply won't flow enough - and if it does it will last all of about 1 day running 40 psi.

I don't mean any disrespect, but have you seen anyone get near these results with an RB25? or RB27? Best I've heard of is about ~200kw

At the end of the day - your car and your money so do what you want. But when its done don't expect people not to say "I told you so"

My 2 cents

This whole concept is kind of like working a 202 or 253 motor off its guts. Lots of time money and effort, for fark all gains, and at the end of the day it ends up a lot cheaper and better to just buy a 308.

totally agree with u on the fact tht ahjosh is a knob and the chick... but u can take a rb25 is capable of just more than ~200kw. im currently puttin gout 250rwkw....

but yea... 500kw even after increasing to 2.7L is just a joke.

he's referring to using a supercharger...

[Sheriff Wan]

Correct joeyjoejoe!

RB25's can make a shedload more than 200rwkw - has been proven many times, just not with superchargers...

RB25's can make a shedload more than 200rwkw - has been proven many times, just not with superchargers...

there's a difference in the exponential power that a turbo makes and the linear power that a supercharger works. Also due to the supercharger's direct attachment to the engine (wheras a turbo works independently off the exhaust) there's a loss incurred. So just because a turbo can let an RB25 make more than 200 easily, doesn't mean a supercharger's gonna be just as easy.

[Neuroglider]

just regarding the rb motor..i can't double check, but isn't there a few 1000hp skylines? what engines were they using? probably would be helpful looking up what exactly they did

[sneakey pete]

What they did? in a nutshell, big turbo, big cams and high boost.

and ....... rb26+ stocker, not toy rb25 and 2.7stocker.... what is the point of that. when nissan made a rb26 and u can very easy bolt a 3L bottem end up or even the HKS 2.8stocker

[R33_Dude]

Getting the horsepower from a supercharger isn't the problem. Getting the horsepower from a low compression engine to turn the supercharger to begin with will be a problem.

Maybe I should get all of my engineering/car manual stuff out and write up a FAQ on superchargers. It sure would stop a lot of speculation... Hell I'm going to do it.

EDIT: Oh and superchargers don't neccessarily make linear power gains. Centrifugal superchargers have a somewhat similar power curve to a turbo due to their design. Hell don't worry I'll write this FAQ up and be done with it.

is it done yet?

[SABBAi]

It's not hard to tell that no-one has done any real research into it.... 2 seconds of RB supercharger kit found one to suit an RB30 off the shelf.

Castlemain Rod shop do a SC14 kit for an RB30. I'm sure you could use that kit and modify the outlet pipe to suit the NEO. As for wasting cash, a complete kit cost $2400. Easy.

Here's the link

So now go do it.

[bozodos]

I already posted linky to that same page fyi

[Modena]

Ok so lets just say that "hyperthiticly" I'm considering supercharging my r34 skyline as im on my p's,will a sc14 supercharger make enough difference to bother with and would it be hard to hide,I'd plan on setting up a hiden on/off button so i can use it when im on the track and then turn it of for daily driving

What will i need? other then the supercharger and do i need to add anything,would i be able to do it myself without any hasel's?

Stick to NA on Ps and turbos on full licence.
