Rb25de How Different Is It To Rb25det

[Jonesy-r33]

Hey all

I know this questions probably been asked a million times but...

I'm doing a swap between my rb25de for the rb25det

yes I know I can put a turbo on the rb25de with changing compression and all that but I don't want to be restricted in hp or anything else...

No I don't want to just sell my car and buy the turbo version I like the kit I got and it was a birthday present from the wife so yeah can't change the car...

I want/need to know exactly:

what is different?

what I will need?

what I can keep from the rb25de and put in/on the det

everything!

I plan to buy a complete engine but if I can get away with just buying the engine and other needed parts separately (only if it turns out cheaper obviously lol) then I'd do that

any help on this would be great!

Thanks

rip old donk out and drop the new one in. plumb all the piping up and swap the ECU's.

Should get you outta trouble, you will have to cut holes for the intercooler piping etc and run a better fuel pump than the NA version.

Just buy a turbo ecu, turbo injecotrs, exhaust manifold, turbo, oil and water lines, crossover pipe, turbo inlet pipe (inc plumb back and breatherpipes), bov and FMIC kit, and bolt it all to your current car, set your ignition timing to 15 degree's and away you go, on stock management you will make heaps of power- more than a turbo model would, just run like 9-10psi, which is all you should be running on stock turbop and management anyway.

Else, if you must buy the full new engine, sell me you N/A engine, so i can put it in the R33 with a blown TURBO engine, thats sitting in my driveway.... (and i'll just bolt all the turbo gear onto it, and make more power than it did before it died)

My N/A+T goes great, only running 7psi at the moment through an R34 sidemount, and its about on par with a lighter GTST, with FMIC and 10psi, but has far better delivery.

standard rb25de are well proven to handle over 300rwkw in competitive drift cars.

make sure you have all required supporting mods and dont cut any corners and the rb25de won't limit your hp, unless you are shooting for well over 300.

[SKiT_R31]

unless you are shooting for well over 300.

In which case, it should be built anyway.

ok how much $$$ would you reckon:

turbo ecu

turbo injectors

exhaust manifold

turbo

oil and water lines

crossover pipe

turbo inlet pipe (inc plumb back and breatherpipes)

bov

FMIC kit

and how hard is it to change ignition timing

cause i can get a rb25det for about $2000

btw thanks for all the advice so far

will be cheaper and easier to buy the whole motor, I have a stock gtst ECu lying around so pm me if you need one (just remind me who you are and which thread or ill ignore it)

btw id still like to know how much those parts will cost if i was to choose to go the +t way

how long is a piece of string?

go on ebay or whatever australian second hand trading site you have, and price it up from there.

buying a crate engine will most likely be cheaper.

that being said, im spending approximately the same amount of money on a +t build, except i'll have all aftermarket gear, a decent tune, fueling to support 300rwkw, and i'm aiming for mid 200's.

Hey skit_r31 the engine has 161,000km how much woud you give me for it
