(IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) Hi guys. Been slow with my car---the weather has not been co-operating with me very much and have not got allot done--car will be going to painters in about 2-3 weeks--

So as now to shift focus on my engine build:

The biggy is carb setup--herre are the motor stats:

*1.7 stock bore and stroke
*Webcam 86
*custom turbo exhaust
*Garrett Tb-03 turbo, 8-10 psi boost nominal--never, ever beyond 12
*short intake manifolds
*Weber 40's with dual blowthru induction ( Like on the buggies)
*Stock 1.7 heads --no porting--just angle cuts on the seats.
*max rpm of 6500--if it will do it....more like 6000 nominal
*stock domed pistons--compression reset to 8.0:1???

Now my delimma with the webers:

They are all stock, 28mm vents, 115 mains, 50 idles, 200 air correction, and F7 tubes.

What would be the collective knowledge on setting up these carbs for a good baseline:

Go to: larger vents? What size? 32-34mm?

what would be a good main size to start with?

keep the F7 tubes??

Idle jet change??

Air correction jet change???

What about those idf update kits I see--are they really any good???


I may as well as get started on this pig now while I am waiting for paint and reassembly.
