View Full Version : Turbo in a vw bug
03-07-02, 02:13 AM
Does anybody know much about the logistics of a trubo on a vw bug (normal aircooled flat four)??
Alternatively, can anybody say much about dropping a wrx donk in? I have been told that one can purchase adaptor kits to put scoobiedoo engines into vw, but not sure if it extends to wrx's. Apart from stuff like hooking up a radiator etc, can any HUGE problems be expected?

Put it this way. A standard Kombie box is good for about 100 horsies. It'd be a big job if you were keen. My mate is building a pretty sik Manx buggy and he's putting 1600 twin port in for now. But he's gonna build a turbo motor with injection and all the fun stuff and he'll be looking for about 80 - 90 horses on a Kombie box. Not much really but when you think about it, 100% increase in power with 600kg of offroad fun... You work it out.:eek: :eek:

Its fairly straight forward fitting the motor with adaptor plates and all the rest but its the BL**DY GEARBOX is the problem.Even a Kombi box with all the mods eg.straight cut gears,anti-expanding plates,Porche CV`s etc etc still has problems with 70kw`s or so.Be prepared to replace things regularly and parts for gearboxes are starting to get harder to get.
Or just dont thrash the sh*t out of it and it will last a bit longer.
My mate drives a bug with a 1.8L Subaru Leone Vortex (turbo) engine in it. I'll ask him if he knows what was involved in the build up (he didn't actually do it himself so I don't know if he will).
The one thing I know is that he had to replace alot of the standard parts pretty soon after as the got chewed up pretty quickly.

My old man runs a EJ20TT in a VW kitcar, it runs a Kombi box. No problems yet. It runs a Sherman conversion Kit. Flywheel, clutch (Upgraded to 2800 Lbs) and adaptor plate.
The thing about VW boxes is that they have a Pus gearshift, due to their gearshift linkage bodgyness.
interesting...I have seenn an enormous number of diferent conversions attached to kombi boxes over the years. they are used in a lot of open wheeled race cars, hill climbers and kombi V8 conversions, and I have never heard of any serious problems with the strength of the things.
Ive been thinking of a turbo bug too, and talking to Hellbug he recons the stock bottom end is fine for 10-12 psi!! :eek: we'll see.
the biggest problem I can see is the length of exhaust pipe needed to the turbo, and the fact the turbo needs to be mounted high up, unless you want to run a dry sump setup.

jazz, if you are really serious about putting a turbo in a bug, go to www.shoptalkforums.com and looking in the forced induction section. That is an all vw forums and they really know what thier talking about when it comes to turbos. If you are keeping it on the street a T-3 is all you are going to need, if you have smaller than a 1776cc go with a T-25. The 1915cc I am building will run a T-3 50 trim, .48/.42 a/r and will be able to run 15psi. ( 1 bar) of boost with some race gas and make around 250 bhp.

Holy 3 year old thread batman. :w:

shit yeah. methinks google is to blame.
The problem with the VW community in general and the americans specifically is they rally behind the cry "But who makes the kit? You can't do that because no-one makes a kit!". Very few innovators.
