scirocco tuning

[salem186]

Hi, Ive just purchased my 2nd scirocco (1988 GT)I had a MK1 Gli when i was about 19 which i sold for 50 pounds.....duh!)) and now i am looking to mod it a little, not too heavy cos i wanna keep it original-ish, but i am having problems finding decently priced parts etc. on the interbernard.
As i know very little about cars i was wondering what an audi throttle body would do as i read that many people have used them, but why? and also what size wheels could i use (offset etc..) as i have been advised to go 15"-16". Would an ecotek valve really help with fuel cos i am used to my old chav SRI which was great on economy so anything would help....
i no doubt will have many more annoying questions
thanks for you time..

Right, I dont know what audi throttle body would fit but it works by basically haveing harger chambers allowing more air to enter the engine.
AS for wheels it depends on personal pref but id avoid 16's as they tyres are more expensive than both 15 and 17's due to them being a rare size.
Ecotek valves basically work by sucking a bit of air into the fuel lines.
Problem with them on a fuel injected car is that they cause it either to run too rich or too lean so id personaly avoid them. (as a rule if it is advertised in max power its no good)

Hope that helps

my rocco is a 1.8 carb, so i take it the ecotek valve would be ok?
and the throttle body i think is of a audi 80? ill check first
but thanks for your quick response...your a star

if its a carb then its not a throttle body you need, its a bigger carb. replace your standard carb with a better webber alternative and you will see performance increase

ok, thanks.
any ideas where i can buy a reasonably priced one or two!!

You want to keep it more or less original?

As you can fit a supercharged 2.9 VR6 for best results.

A stealth turbo setup would be a bit more discreet.

A rebore to 2.0 or 2.2ltrs used to be popular with Mk1 Golf's.

The normal route for tuning VW engines is:

Better air filter and exhaust, cam shafts, vernier pulleys and mild cylinder head modification.

The Weber carb could be a 32/34 DMTL, made as a direct replacement for the Pierburg 2e2 and 2e3, but you may see better gains from something larger?

1.8 20vt conversion.

Oh hang on, "Not too heavy cos i wanna keep it original-ish" Whoops.

rebore to 2.2? on a 1.8 lol, ooooooooooooooooooooooooooook

you could go for twin 40's or 45's both would do, 45's would do better tho usually a few sets knocking around on the bay

On a MK1 block, (still used on MK4's/1.8T) as well as changing crank from the standard 86.4mm stroke, as in the 2.0ltr mod, you also use oversize bore. I think it was 1 or 2mm.

Did need a bit of modding, and was not a very economical way of gaining power.
