I have a 1.4 with an AEX engine tucked up in my freinds farm shed that would eat your GTI's for breakfast
.... Yea its true!! Running a volvo turbocharger, some bizare fuel system my friend helped put together and 3 head gaskets, pumps out a nice 2.3Bar but sadly if i was to put it up against a GTI by the time it has boosted the little 1.4 enough to overtake, the engine would be splatterd alover the road. We only bodged the turbo with every intention of blowing it up but its just been tucked up ever since and still runs.
So moral of this story is, dont bother turbocharging a N/A engine without doing everything properly, It will go fast, but not got long!
This is what we did:
Turbocharger from Volvo 2.3L engine
custom made manifold with volvo plate welded on
Lots of bits of bent boost pipes and an intercooler off the top of a Shogun
Dump valve off my old Celica GT-Four (wosshshshshs)
down pipe hashed and mashed off of the volvo/welded to the end of the golf pipe
one way valve for the throttle body vac pipe (kept poping pipes off)
three head gaskets, two of the thinest and one standard (works best apparently)
Bit of retard on the timing and diffrent spark plugs
A Bosch fuel rail and loom which i stayed well away from (i tend to destroy injection components
)
It took alot of time, far to much money thrown away and still its really not even safe to use without blowing up... To do it properly you really need diffrent pistons, full overhaull, diffrent gearbox? (on smaller engines you do anyway)
