I have been told i can change my na skyline RB25DE to a RB25DET by fitting turbo, intercooler, ecu and manifold?

Is this correct, would the head not need changing?

hi, do a search on a fella call "lammy" hes done his, and will be the font of knowledge on this topic. im not sure if you need to change the head, though i doubt it. i think the only difference is an oil feed.

main thing is changing the head gasket, its the thickness that changes and therefore the compression ratio.

in the true sense you would have an rb25de(t) as the pistons and such are different internally, and compression is therefore higher on the turboed de engines than stock det.
(power is also limited to 330 ish ...though lammys pushing this)

I have sent him a PM thanks for the contact!

m8 just go with a turbo engine swop and sell your engine get some cash back would be alot easyer
Well you have all the fitting costs plus most the engines don't come with the turbo, ecu or any other bits + the engine in mine is worth fudge all!

Standard turbo costs about 50p and then ecu, manifold! I already have a FMIC!

cost wise its pretty much of amuchness, either route is gonna be close to 2000 installed.

and to sell a non turbo you'd need to find a geek like me, and we're kinda rare.

Not as far as i see it! If you buy a standered used turbo, manafold and ecu (i already have a fmic) and a mate who will fit it!!!! Won't cost bugger all!

Just found a top mount manifold for £50 on fleabay and ecu with 22 hours for under £2!!! Shouldn't be too dear to convert but i will wait to hear from lemmy!

beware cheap manifolds, particularly xpower. they crack.
