Suggestions please, on intake setups and the like Options

(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.

(IMG:http://www.914world.com/bbs2/html/emoticons/rolleyes.gif) Yea, I know-----but I am going to do this---so as I can offer a one stop shopping for anyone else who wants to turbo a 914---all I gotta do is get this done--and yes it is a mild combo---but once I finish it and prove it out on the chassis dyno I will be able to offer the correct components---just wait till I get it done---it sucks beiing on a very stringent budget--but at least others can see what is possible with a pretty bone stock 1.7 -----

It will be a drop in just like the rice tuner guys have access to---the most anyone will have to do is drop the front of the motor down about 8 inches to move the rear heat bulkhead---

Since I am using a TB-03 turbo---people can buy whatever trim turbo they want and still be able to hook it all up--as long as it is t3 flanged--Do not get me wrong--it is going to take me awhile yet--but by mid-summer it will be completed----

I just need a starting point so as I do not toast my motor on the first fire up---if someone would share thier setup for a large motor----+2200cc's--I can extropolate for my 1.7 setup----

So basically it will boil down to a prefabricated rear bulkhead tin---all the flanges and ducting--the exhaust--and the correct jetting combo which I will achieve on the dyno.--yes, single or dual carbs are a must--you all know the limitations to the stock FI system--but single carb systems are still good for 200+ HP if done right--

All anybody else would have to do is procure thier own turbo--I do this because the vast majority of us simply cannot afford a built big motor--and I got my turbo from a volvo in the raping yard for 50 bucks--

So hopefully for only a minimal investment, you can have 160HP+--

And more importantly--the BRAGGIN RIGHTS!!!

For 1/3---1/2--to 1/10th the cost of a built motor--
