General turbo change

[iancookie]

i'm in the process of changing my vl37 to a vl38 and was wondering what the best way to go about it is?

i've stripped away all the heat shields so i can get a better look at the turbo and manifold... is it a case of replacing the WHOLE unit...turbo and manifold connections? or can i simply get away by uncoupling the turbine from the manifold and sliding it inside the old one?

seems like its gonna be a HUGE job if i'm replacing the whole thing.

i understand the manifold/exhaust sections are the same on both and it is just the turbine shaft that's different and the inside geometry of the actual turbo...?

local garage quotes about £100 to swap my turbo, i would also get an oil and filter change when you fit the new one. Its not worth the trouble to fit it myself for the money

I got quoted £60

did it myself yesterday, used the existing exhaust housing. didnt take too long really but there are a couple of fiddly torx screws on the bottom oil feed.

the car drives totally different than with the VL37...really want a remap now

You should make good power from that vl38 turbo , as i did ! before i had my car mapped it made 167bhp with that turbo on and no remap.

But it was probably a combination of having straight through exhaust , forge front mount , and a panel filter !


Overall i made 192bhp with 258ftbs of torque !

yeah it feels a bit slower if anything with the new turbo, old one used to kick in at about 1500rpm but with the vl38 you have to rev it quite a bit more up to around 2500-3000
