wooot ok so

would there be any problems with hooking up a rb25de head/3L with my rb25det powerfc?

that built motor from RIPS is a rb25de head so no vct the owner recons i would need an r32 ap engineering computer or remap the 32 computer he will supply with the motor at no extra cost what are your thoughts also is it true it will use top feed injectors? and I think i heard that the cams slightly differ from the det - true?

dont tell shrek im still thinking about the 25/30 he might hurt me lol

what head is on the rb30? r32 or r33? r33 heads have slightly bigger cams (see pic below)

the r32 rb25de head has smaller ports than an r33 rb25de or any rb26

the r32 rb25de runs top feed high impedence injectors. r33 rb25de head runs side feed high impedence injectors

N/A valve springs dont like big boost. cams & springs are interchangalbe for rb20det items

too late, he's prolly already read this lol

edit - Might help if i add the pic huh :P

nothing a bit of porting cant fix. plus both r32 and r33 heads have the poo valve springs (being na) but i believe guys have onyl had issues up around 20psi.

i reckon r32 is the better head if ur not gonna use the rb26 head caus of the no vct. plus the 32 ehad is top feed injector already (better selection)

hmm yeh well i guess depends which way you look at it aye

rb26 head would be nice! but $$$ sill considering that built motor from RIPS just trying to get my previous employer to cough up some of the cash he owes me and all will be apples!

one thing u need to look at if u put it in ur 33 is the std plenum clearance to bonnet.

options are either:

a) modify engine mounts and drop motor

or

b) get forward facing plenum

i'd go b, as itd help u make more hp :P

I can. Tourquing up a set of stock GTR rod bolts when one let go 20ftlb short. New set delivered and some were a fair bit longer on the old ones so glad one snapped. So much for all the folks think they are fine to reuse.

Dano, I run a 26 head in mine on a 25 PFC. There is plenty can be done to overcome the small issues.

And that motor has standard internals?

Can anyone say stretched rod bolts.

ive gotta say i disagree with you mr monster. rob has a damn good rep with his motors and if they are run as he has specified they dont break.

however i do remember him saying the std bottom ends he says to cut the revs at 7200rpm

taken from his site

RB30 Stock internal bottom ends start at NZD$3500 (suit up to 600hp and 7200 rpm)

    • So, this shouldn't be such a mission, but there were a few tricks so I thought I'd post up a DIY for it. This was on a Q50 Red Sport but I doubt any other V37 model is very different (maybe just less steps for the intake heat exchanger hoses) I pulled the radiator out to flush it because the car was running hot at the track, but obviously the same steps apply for changing a radiator for any reason including an upgrade. If you are removing the radiator, you of course need to drain and refill, so have 5+ litres of blue coolant ready. You don't need to drain the intake heat exchanger to remove the radiator but depending on your plans you may need a couple of litres for that as well. You will also need something to deal with the auto transmission lines, I used 2x 8mm rubber caps on the radiator side, and a short length of 8mm pipe on the car side.....unless you can block these lines quickly you will loose AT fluid and it may be enough to hurt the transmission if you don't refill it. Other than that....lets go... "First, jack up your car". Yes really, and put it safely on stands. If you are not confident doing that you need to give this job to a mechanic
    • If the forester is anything like our old 2007 GTB Liberty, I could near on run ling Long's and "rate them", as no matter what, it just hung to the road, even when abusing it in a hard launch in the wet, or throwing it at corners.
    • LOL, all of the CAI like Craig I just need to put a hole saw through my bumper Done and dusted, the car runs, which is nice, I'll take it for a spin when the weather clears up Just need to put the bumper back on for good

    • Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
