rb25det hp?????

[drifter2180]

hey I'm planing on doing the rb25det swap and I have searched but maybe I have not looked in the write places. how much hp can the stock block take? and how hard is it to make like 500hp? are we talking like turbo upgrade, ecu tunning and other misc stuff or is it alot more difficult? my plans are the rb25 motor big single turbo, greddy intake manifold, ecu tunning, and your basic exhaust and other small misc stuff. any help would be great. thanks

a turbo, injectors, and a tune will get you to 500hp.

But there are better ways of wiping your butt than using sand paper.

I dont think I would trust stock pistons for 500HP. I think they would be good at 400. If you decide to try 500 make sure you have a very good tune.

A smooth motor is a fast motor.

To reach 500 safely my opinion: You need a good set of race bearings, forged pistons, 500+CC injectors, ECU, A decent size turbo. I wouldnt go too big or else your creating more bad than good. Lots of LAG!!!! Cometic Head gasket, Good intake & throttle body combo, Turbo manifold, ext wastegate, z32 MAF, Then your getting into machine work because your not going to find pistons that are std. So now your looking at block bored, I recommend balancing the assembly, You will be extremely satisfied on how smooth it runs through RPM's, Cleaned, Clearances all checked, including rods and mains, More than likely it will need the Deck cleaned up for a good head gasket seal, So honestly your looking at a good 1000-2000 in machine work. Then your looking into a good clutch to hold the power, I like Cusco Exedy myself, Never had a problem. So in simple terms Unless you have 10,000 to spend I wouldnt attempt 500HP Do it right the first time if your going to build it.

Now you can make a good 400 with just a simple turbo, injector, ECU, Head-gasket upgrade. Internals will safely run that.

Hmmm. I have been making 600hp with mine for a while now. Stock head and factory head gasket, stock bottom end with over 110,000km on engine. 1.2 to 1.5 with a T70

Yeah, and you still got pulled on by somebody else with a stock RB25

BONG!!

[drifter2180]

600hp on stock block. nice

[Fearsome_tea]

Yeah, and you still got pulled on by somebody else with a stock RB25

BONG!!

Yea but you was 1.2 and I was at 1 bar with old tune. And you are like lighter than me I am a fat car.

[Cjmartz2k]

Well, we can both turn up the boost and we are both only half tuned. But your right, your car is a fat *** 33

So I guess we are the stock motor "how much hp can I make" guinea pigs around deez here parts. It's a lot easier when a new RB25 is $300 from the junk yard though, eh? First one to blow there motor is a rotten egg!! (I hope I didn't just jinx myself, knock on wood).
