Engine Build Question !

[jimbo32]

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!

=)

Good insight thanks and yeah I should have mentioned that it's a full build .

Cheers .

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,

[jimbo32]

What turbo would you suggest ?

[krzysiu]

Difference between de and det is that the det already has drilled out plugs for your oil feed/return

[jimbo32]

Turbo suggestions anyone?

How much power you want

[Deanc]

i Have heard that garrett have a new range.

want good power go like 35R (AKA 35/40) will be a bit laggy but on a 2.5 but if you went a 3ltr

it wouldn't be so bad
