Outer Limits 4x4 Board

Im after some info on people who have turbo there 1.3 with a blow thru setup and what carby they ran?? im not doin a draw thru or going fuel inected so dont bother asking why dont i do that. so any one out thre who has done it got pics and what carby you used thanks.

might i suggest a small holley as they are easier to tune and get parts. Just be sure to keep an eye on the float as normally this needs to be filled with foam or an aluminium one used depending on boost pressure as they calapse under pressure otherwise.
I only have experience with turbo carby V8's and efi but i suppose the theory would be similar.
perhaps these may be better suited to forced induction, but do not expect to find a cheap solution.

In all honesty, if your turbocharging a car and not goin injection your wasting your time. Having played with plenty of turbocharged motors, injection is the only way to go.

Have a look at some of the VW sites. Most use the webers. Good for about 7psi blow-thru setup. Weber 32/36 with a pressure referenced fuel bowl and high pressure fuel pump with rising rate fuel reg will work. Just remember to knock your timing wayy back.

i haven't cad a carby turbo zook but i had a mate with a turbo 2 ltr escort with a webber, went well and was pretty good when it was set up. it did take some sorting out. biggest thing with a boosted carby is to get a boost reference fuel reg and set that right or inclose the whole carby.

holleys are very easy to work on and every one knows them.

why not use a stock carby and rejet? unless your going for all out power but as lat80n said injection is the best way to go

yeh been thinkin of using the stock carby butnot sure what people do with the bowl on them, i don wana go injected as i dnt have the funds and its not gunna be a power plant just to give a bit extra when i need it, any one got any pics of the setups??

you don't need to do anything to the bowl on it if you run a boost ref reg and no more than 7psi. just make sure the carby is in good nik.

are these boost ref regs the same asa rising rate fuel regulator?? got any idea where i can buy one online??

These would be the most common on this setup i believe.

there are a few different types of malpassi regs.
the ones i know of are,
black EFI
silver EFI
double diapham carby type.
they still have the boost refrence rising rate but from a lower pressure

just drill a hole in the top of the fuel bowl, tap a thread, screw in an airline fitting, run airline to your boost. easy boost referenced carby. you may need to up your fuel pressure (or drop boost pressure) if you find that it is always leaning out

This guy has got some insane results from a backyard 1.3 carby turbo set up, read through ti'll the end, you'll learn all you need to know, he even has drawings, and instructions.
