gday ,

Im looking at buying an RB25 engine to build and drop in an R32 gtst.

RB25 det engine, loom and comp are going for about $1200-1500 .

RB25 de engines for about $700.

My question is should i go with the det or de then turbo it ?

has anyone done this and what are the pros and cons ?

regards jimbob32

i don't know much about engine rebuilds and what not..

but...

depends on what exactly you will be building?

i mean... r u rebuilding every part?

eg.. rods, piston, cams etc etc...

if your getting after market and forged, custom and all that then wouldn't it be smarter to just get a normal rb25de?

your gonna strip it and replace/build pretty much everything?!

so i don't see the point of paying extra for parts u dont need/won't use.

unless your not doing a full rebuild and just here and there parts then obviously better to buy det engine as stronger components?!

hope that helps.

correct me if im wrong guys!

=)

I'm pretty sure the de and det blocks are the same strength wise. The only difference i know of is the de has higher compression and softer valve springs. Putting in turbo forged pistons would remedy the high compression side of things and getting some decent aftermarket valve springs suited to turbocharging would be needed.

yeah it sounds like the way to go its decided then

one de engine 2.5ltr

t04ze garret turbo

greddy intake plenum with oversize throttle body.

better pistons , rings , valve springs ect undecided on make will have to research.

full reco vor gasket kit.

and a few other goodies .

soon as i get all the bits ill put up a build thread .

thanks for the advice people !

then ill have to find a 32 to drop it in .

If you're going to all that hassle, why not go only a little bit more and buy a trashed out RB30 from an R31 or VL, then make a RB25/30?

Also, I'd be finding a better turbo, T04z is a dinosaur of a unit, there's heaps of better options these days,

    • They see me rollin' they hatin'....... Took me most of the day to make the necessary mods to the mounts to make them fit the car.  Fortunately I was able to just use the mounts that came with the rotisserie. The rear ones are really secure, the front I feel i might reinforce a bit more as it doesn't seem like enough attachment to the vehicle. I'm sure it's fine but better to be safe than (extremely...) sorry.  I drilled and tapped thread into additional M12 holes to each car mount where it attaches to the rotisserie as an extra fail-safe. Without them the side to side movement is just restricted by the allen head pinch bolts, nothing actually goes though the beam. Does now! I still need to adjust the rotisserie to get the car centred in terms of centre of gravity. If it's too high or too low relative to the rotational centre line of the car, it will be like a turtle and roll onto its back or as it currently sits, I dont think I'd be able to rotate it as it sits as it needs to lift the whole car up as it rotates. Ain't happening... I'm going to be nervous as hell the first time I go to spin it on its side...    
    • Oh yes done this when the window started flopping around.  Turns out the guides that run along the rail chanel had crumbed way. Took off the door card and pulled out the window mech, then the window, which you have to pull out through the top. As said unbolt the guide rail and don't spend 30 minutes getting frustrated trying to find a way to slide it out upwards cause that don't frigging work. Drop it down and out through the door hole. All I did to repair it was slice some 10mm clear plastic tube, vertically, then screw it to the guide rail both sides. This tubing rolls inward on both sides and leaves a gap wide enough to hold the window. To finish all I did was lube the plastic tube with olive oil and Bob's your uncle . . . well if he has the operation he can be your Aunt ! !  10 bucks in plastic tube and another 5 minute job done again . . . . YEH BULLSH#T ! My love for Skylines knows no bounds !
    • So was there a solution to this problem? I’m having this issue now. 
    • not expensive, just irreplaceable if you don't go sub 60 at wakie in that thing people will start talking
    • I haven't replaced that, but I have had the doors apart on the r32 a couple of times The door skin will be held on by a combination of clips and bolts, just take it slowly and make sure all the sneaky hidden bolts are out Once the skin is off you should be able to pop that piece off pretty easily, looks like there are only 2 bolts holding it on
