A 2530 isnt all that different to the std turbo. (yes i know it will make a bit more power, and probably come on a little harder then std as well...but in the world of turbo upgrades it is pretty close to what the std turbo will do)

Thats not to say its a bad choice. Just that i would perhaps think twice about throwing $900 cams at en engine using a turbo as small as the 2530.

That said a friends R33 use to use a 2530, it had baby cams and a greddy manifold and it was still the best, and probably one of the quickest street cars i have been in...it was also damn quick as the track the couple fo times he was good enough to swap keys with me.

C'mon Troy!

A 2530 is heaps different to a standard turbo. Just cos you can find someone with a stock turbo making 200rwkw and someone else with a 2530 making 220rwkw doesn't mean that the second guy wont shit all over the first. We've all seen 2530 powered cars beating much higher peak powered cars.

Sorry, i didnt really make myself clear. What i was getting at was perhaps you should think twice about using cams with a 2530.

I would highly rate the 2530 on the RB25. Like i said a friends old engine ran that setup and it was a briliant street car and very quick on the track.

What i was alluding to with regards to the size of it and the size of the std turbo is...ppl have shown that cams on a std turbo engine doesnt really do much at all. So was just cautioning that with a little 320hp turbo slapped onto the side of the RB25, cams may not give you the result you hope for...

As for 2530 on RB25...just make sure you have good tyres and suspension because they come on hard, and do everything you can to open up the exhaust as they tend to dropa few psi up high in the rev range

Ahh, that's a fair enough comment and may be true. I don't know anyone with a 2530 and cams but perhaps the higher boost capabilities would make them worthwhile where they are not with a stock turbo due to the boost restrictions imposed by it's fragility.

If looking at highflows check out some of the threads on them where we discuss the R34 and VG30 exhaust housings and how they are bigger making a highflow one of those better than a highflowed R33 turbo.

But that requires new manifold, an external wastegate...a hell of a lot of attention and expense for insulation of it and protection of all the engine bay ancillaries. Not saying its a bad choise, but a bit overkill for the power he is after .

Are you talking about the KKK or Garrett, cause the GT3071R needs no mods like that.... compariable to the HKS GTRS

      I'm hoping I just don't have to do an engine rebuild NOW. Doesn't mean I won't do it at some point. I think a plus point is that the car presumably ran on or close to stock power nearly all it's life so far. Only the Owner I bought it from actually increased power with a standalone ECU and blew the OEM turbos. And after it got thee 2860s it wasn't driven an awful lot either.   That is what I meant. With the twins coming on so late (4500-5000rpm) I hope the rods won't want to exit the block prematurely. And it still being a 26 means the torque curve isn't gonna hike up all that much.   It didn't blow up on the dyno when they tuned it to 500ish crank. So I suppose it'll be okay for now. They did put a Tomei head gasket on first though which did not seal at all, and they redid it with a Cometic one. Which I hope won't be my water leak.   Mainly anything oil. So far all it has is the N1 pump, oil restrictor and a filter relocation kit with a cooler.

      Comfortable replacement seats for R32 GTR

      By GTSBoy · Posted

      15000? ish? Something like that anyway. It wasn;t so much a wear as a tear that then spread. Might have lasted a lot longer if not bothered by just one incident, whatever it was. I took a punt. They are really comfortable and do a good job of holding. My daughter HATED it when I first put them in, and probably still does now. She has sensory issues and hates the way they are all up your business. I'm 197cm and 95kg. Not fat or particularly wide, and the XL size seat is the rigth fit. If I was any fatter it would start to get too snug. Any skinnier and you'd possibly want the smaller width.

      The NA 2.5 has very little torque. You won't feel much. Those trannies are also a million years old now and it could well be f**ked. First generation electronically controlled autos will often refuse to kick down, ete, etc, depending on what's wrong with them.

      Yes, but no but yes but no. Those "it's fine up to 500HP" rules and everything else like it were all determined back when the cars were 10 years old. As they are now 30 years old.....what do you reckon the chances of something shitting the bed are? I'd say they are much higher now than they used to be. You might be lucky. You might be unlucky. Spin the wheel and find out. Yeah, nah. It's actually exactly the opposite. Making boost early and having heaps of torque able to be generated right in the middle of the rev range will do more to damage an engine than having to rev it high to make the power. Think about the load on the conrods, bearings, etc, to make 400HP at 4000 rpm, vs 400 HP at 6500 rpm. So someone has already "let the Nissan out" which is how we describe the increased chance of a fiddled with engine to have had something done wrongly. Many more engines that have been opened die than stock ones do - even if you into consideration how they are treated wrt power levels and the like. Again, not saying that yours will definitely have been put back together by a moron. But the possibility does exist. It's still a lottery. Spin the wheel. What weakspots?
