Return Flow Coolers

[SimonR32]

$4500 approx delivered would seem very very good value considering...

I wonder if "600hp" is flywheel or wheels?!?

[joeyjoejoejuniorshabadoo]

that's looking like a goer atm... but with the high capacity sump ARP rod bolts and studs as well as VVT

As far as I understand RIPS won't have a neo head lying around.

So you will probably need to prep your own head if you go this way and just buy the bottom end with the required fruit you have just listed.

Wow..thats actually alot more affordable than i had imagined..

Well worth considering

What would a quick rebuild on a 25 block set you back, im thinking 1500-2000 with rebore, quality bolts, bearings and pistons.

Only thing Im worried about is your turbo not liking the extra capacity cause then your going to be forking out for new turbo as well, then you would probably need new injectors .....................

And so on the snowball begins.

the rips motor is a 33 2.5lt head

i dont think the turbo will fail on the motor.... it just might creep a lil

[ARTZ]

Maybe,

Does your turbo drop off now or would it handle a 8-8500rpm redline?

Cause i get the feeling that some more revs and some extra comp (say 9.5) would make it deadly fast and responsive. But im only guessing.

Are you talking about if he stayed RB25?

His turbo would not handle 8,500rpm redline on an RB30. I think joey would be happy if it handled 7000rpm well on the RB30. That was my point that 9.5 comp would be super nice on the RB30 but I think the RIPS standard refreshed engine is a great deal.

Yeah was talking about a built 25..

RIPS is a good deal but is it compatible with his current setup is the big Q. I mean its no good getting it to find out its not, then you have to spend as much again to set it up properly.

But a decent bottom end that can handle 8000rpm , decent pistons alone could provide some extra torque, It may not make much more power but it will make it quicker and stronger for longer..

Plus buying an engine form NZ means alot of hassles if it plays up, not like u can drive in and complain, and there is plenty of good engine builders nearby his area

Im not knocking the 25/30 at all just adding another point of view.

yeah i'm just trying to research it all atm... that turbo was still climbing when it was shut off at 7400 but not very steeply

i'm thinking that it's really not that much smaller than the 3076 .82, so it should manage a redline of 7000 or just shy of...

[R31Nismoid]

I think you'll find it'll be over a lot earlier than 7000rpm.

I'd take a stab @ nose over around 6500rpm, its what, 20% more capacity.

But then it will be on in almost factory turbo fashion

[Harey]

The HKS 2835 Pro S seems to have just as much top end as a 3071 0.82 on an RB25. And there are plenty of results similar to the 3076 0.82.

Even if it does nose over just before 7000rpm that would still be a very nice setup. The other thing I was thinking of is that the HKS 2835 Pro S came in a 0.87 exhaust housing although I am not sure if it is T3 as well. A 0.87 exhaust housing would be ideal imo

[joeyjoejoejuniorshabadoo]

yeh... i'm thinking this should be a goer

worst case scenario will be a new rear i spose, but if it makes 6500, i'll just set the redline to 6,800 and be done with it

Even if power drops off, as long its more power than the next gear up at that speed you are still better off revving it out to 7,000rpm or whatever the engine is safe to. Same as how a standard turbo power drops off over 5,500-6,000rpm but you are still better revving it out to rev limiter.
