rb25/30

For that money...forged pistons & stock but balanced everything else. Maybe shot peened rods or cheapie aftermarket ones.

I thought I read a while ago you were saving for a deposit on a unit Phee?....

If it was my decision, I'd go the detuned RB25 front cut option (and sell the extra bits), downsize the turbo a little and just enjoy it.

[Kiahatsiu]

What Psi999 said. Maybe some aftermarket cams.

Buying a unit would be much better in the long run. There is only so long one can live in their car.

yeah sell the other crap and do this

"TJs on the ball - everyone has seen RB25s with Jap cams, fueling, big turbo, good management do well well in excess of 300rwkW with excellent reliability on 95 ron. They should spool in the mid-3,000rpm range."

on a good RB25DET front cut. Hell I'd even look at ditching the motec for something cheaper/simpler. Ohh and it might be worth the coin to put it on a transporter and send the car to Dale or something else. Choose someone that seems to know how to keep them together in the first place.

Sounds like it was a dog of a thing to start with where some twerp built a "I got this massive turbo on my skyline bro how sik am I car" and unfortunately you've inheritted all the associated problems.

If this was a poll Id be voting "standard import engine but put a decent turbo on it and get a good tune" Selection.

Be crazy to ditch the motec,

once its setup, leave it alone, and it will cause an issue.

id be voting 25 with pistons rods and cams, good tune!, and a very quick street car

Yes but it's Darwin and there's barely enough good tuners (especially for something as spendy as a MoTec) in the rest of the country let alone there.

[TonyJZX]

I would have trouble finding a competant and cost effective motec tuner in Sydney!

[Nick]

Put a 2JZ in it!!1one :rotflol:

[MartyHusseinXF]

So how many people here have had a mildly modified car which ran well, something went wrong with it (like blown bottom end or head gasket or whatever) then gone all out and put some more serious mods on, then regretted the unreliable, noisy, loss of driveability type car they have now then sold it?

[Nick]

Or, done something, something has gone wrong, fixed that wrongness, had a few bugs, fixed bugs then car is perfect only to be sold.

[wiggah]

The good thing about talking about all this on PF is that because Darwin is small, word spreads quick and I want to have a discussion with people that know their shit without running off to tell everyone they know. Yes, Darwin is that bad.

I would say its not really anything to do with Darwin in general, but a particular crowd of tossers. Let's hope they stay at boostcruising.

Ill agree that is a very valid point

Maybe swap motec for a power fc and cash ?

Likely shell need a new loom is this ones been hacked to suit the m600 , but thats not too big an issue, im sure one could be sourced with ease.

If you are looking for engine builder options, these guys post a bit on various forums and seem to know their shit re RB engines:

The idea that a secondhand RB25 engine is going to be reliable and good value is ridiculous. RB25s are dear as poison because demand is high due to the fact that they are a shit engine that can't take much power.

Here's the scenario, Phee buys a front cut of an R33, that costs $4500 for a manual, she then pays at least $1000 for freight to Darwin, she then pays 4-5 hours labour just to remove it from the cut. The std engine is then on the edge because it is an RB25 and it has no warranty because it is modified. The engine lets go for the same reason the other engine did. Total waste of money.

Get 10secRX7 to have an RB30DET built. Guaranteed result AND an improvement in driveability, reliabilty and power(all on shitty NT fuel).
