1.- Chip. Will get you about 200 HP.
2.- Chip + bigger exhaust + downpipe: Will get you about 10 to 15 extra HP
and more noise.
3.- Number 2 + mod cataytic conv + kK04 or KK3 sport turbine. Will get you
around 230-40 HP with specific soft for your new turbo.
4.- Number 2 + bigger turbo + bigger injectors and fuel pump + additional
plumbing. You'll get around 300 HP but more turbo lag and sharp power
delivery which needs an expert driver to tame.
5.- Number 2 + bigger heads so that you're getting more cubic room + lots of
other mods, the sky is the limit.
I went for option 1 but I'd love to test numbers 4 or 5, though I doubt I'd
want that done to my car unless they were real pros.
JP, its a 2.8 not a turbo :), if your in the UK thats a 30v model, not much
you can do apart from chip it, which doesnt do much, new exhaust, perhaps a
K&N, it already has 180bhp, i have the 2.6 12v quattro,150bhp job, there not
that rare either, theres tons in the uk :) mines a 97 P which they replaced
with yours, they stopped making the 2.6 12v in 96.
Oops! Righto! I seem to have misread 2.8.
Agreed. Not worth doing much about it. I seem to remember some tuner fits a
PS28 turbo into the 2.8 thus turning it into a monster. I would bet
reliability is not its strength though.
It's a supercharger (intake air compressor driven by crankshaft) made by PES, I
believe, designed to fit in the middle of the Audi V6 2,8 NA engine.
A Google search turns up a number of references.
But I do wonder what mods, if any, need to be made to lower the compression
ratio . . .
You definetly need to change every single vaccum lines out. Our engine
produce lots of heat under the engine. I never liked the way the braided
cloth hide possible leaks. I've heard of other people pull their hair out,
trying to find leaks.
Another one is installing a catch can, to separate oil.You don't want it
coating your intake track. Also change it to a TT bpv 710. New clutch, I
burned thru thru stock on in 7k miles :) Then burned another aftermarket one
in 11k (I have my doubts on that brand tho) I'm on a spec stage 3 4 puck
clutch now, holds like stink and it's been over a year.
If I remember anything else I'll post it here. But for more info on Apr
stage 3 owners. Drop by www.audiworld.com Over in the B5 forum. Lots of guys
there, I've meet a bunch of them over in alabama, USA. Apr has a yearly bbq
