supercharging r33 na

[Let Me Drive]

hay guys iv been seeing all the conversions to turbo but what about supercharging the rb25de that would have to increase the power and still have all the reliebilty of the na so what do people think and who could i get to do this in melbourne Victoria. any info would be great

It has been done before, I am sure there are people on this forum with this conversion done.

hey, i have heard from a friend of a friend that he did the same thing, he said it went well and didnt cost a bucket but he broke the gts gear box and upgraded to the r33 gtst box. never had a problem since. not sure of where it was done though sorry. good luck

lol @ friend of a freind stories...

anyways, a guy in melb has done it, and for the money spent he gets less rwkw than a stock GTSt does. However looking at his dyno chart, due to the difference in compression in his engine and the linear boost of a supercharger, he has a much nicer torque curve and better response out of the car at lower RPMS.

So basically it comes down to what type of person you are... are you :

a) a traffic light drag superstar

or

B) a dyno figure bragger

I've looked into it greatly (to the point of getting exact part numbers required for the conversion and finding someone willing to fabricate the manifolds, and buy parts like a supercharger off a Toyota Straight 6 Engine, a Q45 Throttle body, and my fujitsubo extractors). then decided against it and went n bought a TD0625G

If you need some insight into it search for "supercharge RB". I've had numerous highly enlightening discussions with people on this on various threads.

thanks man yep i read through the threads and i think im going just to make my car a all look and not much go but then again im not one for drag

Go to search, look up "supercharging" or "supercharged"or something along those lines, i had a monster thread on this about prolly 9months or more ago. I was keen on the idea, but the means and the $$$ dont justify the end result IMO.

I feel the engine bay in my r32 was just to cramped for decent sized charger, and finding turbo accesories is just so much easier, coz thats whats intended. It was decided that a charger worth fitting to justify the hassel was going to cost about 3k........2 k more you got the rb25 half cut.......alot of expensive fabrication and stuffing around, labour costs start to look similar.....but hell!!! I'm all for ppl wanting to be different. So if you wanna do it.........go for it!!

P.S - The compression of an NA engine was one of the stumbling pionts, there were 2 ways around this outlined in my thread, i propose a 3rd. Swapping to the N/A series 2 vl bottom end...compression down to 8.5.1 or 8.7.1 - sometihng around that mark
