yes, i was arguing with VeedDub about fuel economy, as he say turbo has more fuel economy potentials.

veedub,
i forgot to say, that your turbo will be fuel effecient, only when you are off-boost, i don't know why as i'm not an expert, but i'll assume that because your engine will not make any force to suck the intake mixture, but this will end as soon as you go on boost, so you will rarely see this happens.
a user in STF (i don't remember his name), built a 94x69 turbocharged engine megasquirted with EDIS. i remember that this guy fine-tuned his engine for ages and he did a great job finaly and do have a lot of experience about turbos, he was saying that his mpg was 22 only on combined driving(on-off boost), many users didn't see more with the same setup.
if you can live with this mpg, go turbo, you will be happy with the power, but at least FI it...

Michael

Yes, again I agree with you. However, I do think that you can get a decent MPG with and EFI & turbo engine, IF you are mild on boost, which also helps drivability. Do you remember how much boost did this guy have?

I got more info on the turbo idea. If I get everything forged, pistons,crank,I beams, rockers, I can run up to 15psi and be reliable. Talked to a guy thats had his kit running 15psi, and has had it for 5 years now with no major probs. Oh and hes making 140hp (138whp)

Yes but that makes the price go to sky. Cimas aren't forged, or so it seems. You are gonna spend some bucks on a forged 1600cc, and then a similar amount on the turbo.

yeah, come to find out his was a home made turbo kit. He never mentioned that...

I talked to Darren from DRD on the volkstalk forum, I was telling him what I wanted, a daily driver with a twist, for the temptation of just wanting to nail it on the straight aways here which everyone does thats my age anyways.
I was telling him Id like a 1641cc, and I knew about the pistons, not like I plan on overheating my car anyway
He told me
87mm pistons forged
69mm c/w forged chromoly crank
118 Web Cam cam
Dual throat Webers 40mm
Merged header and Super Turbo Muffler (I added)
Stock heads ( but I dont want stock heads)
combo is good for around 90hp 130lbs torque.

Seems very well. I only say that you better get P&P heads, even if they're mild. And if you are going to spend in machining anyway, and you are also gonna get a new set of pistons/cylinders, why not go with 90.5's?

Well, 87mm pistons dont require machining and there less expensive.
Also for heads I was thinking of DRD's L3 heads,
specs on them
This style of head porting is for a street car/ off road car with a increase of approx 30% more than stock hp and flow.
Power output, depending on your combo, power ranges from 75HP to 125HP.
A full port and polish, small port, combustion chambers reshaped, intake manifolds matched, fly cut for
compression, comp valve job, springs shimmed to your cam and rockers, and flow bench tested.
This port combo retains bottom end torque, with excellent mid range and high end pull to 6500 rpms and increased
fuel mileage. For use on stock vw castings with stock intakes an stock exhaust valves.
Recommended mild cams shafts and mild lift .400 ~.450 numbers at the rockers.
DRD L3 porting labor per pair, includes Bead blast cleaning $275.00

And specs on the 118 Web Cam perf. cam
Valve lift .402"/ Dur of cam .283"/ Dur. at .050" .246"/
$87.00
