Is this possible on the MK1's? ...If so,how do you convert the injector housing over...I was curious to know if injector inserts, part no. 034 133 555 can be used to solve the problem?
-
you can buy injector seats to adapt to efi. not sure of part numbers but I think tsr do them. probably other places to.

These are what I require...have you guys encountered them on here, Later Golfs Maybe?
-
It's not the availability of these components that I am interested in, it's the suitability for use as an option to the brass CIS insert... So, nobody on here has gone from CIS to EFI with a standalone ECU and installed thes babies?
-
the black ones in the pic are definitely mk2 gti efi inserts so if you remove your cis inserts and measure them and they are 22mm diameter then the black ones should fit. according to the table pre 84 had 24mm inserts. I take it yours is post 84?

I think I need to explain that I am kind of scavenging information from as many VW sources as possible, for my Audi 10v 5 cyl, KV Eaton M45 supercharging project - basically, a 5 cyl version of the early Golf CIS, hence, my presence on here! I need to convert to EFI and I would be gratefull for any assistance from your members, to overcome this small hurdle.
I think the best way forward, will be to compare the thread sizes of the CIS Audi brass inserts and see if the are the same thread pitch as the 22mm black inserts
Cheers!
-
yeah that's the best way. why not buy one insert just so you can double check. then if its right buy another 4. surely they are not that pricey?
-
infact I have an efi head at work. if I remember tomorrow I will pull an insert and measure it.

hey measured an insert today for you. it was 22mm diameter with a thread pitch of 1.5mm. they are the shorter black ones in the pics and the number on it was 037 133 555. hope this clears it up for you man.
-
Cheers Gaz,much appreciated, I need to compare this to the thread pitch of the brass CIS inserts now...anyone got one handy? and then I'll leave you all in peace!
-
10v cis engines had the 22x1.5 injector seats. so you can screw digifant 8v seats straight in. They're still available from the dealer too! If you did have an odd cylinder head with m24 seats, you can use modified 1.8t injector seats (agu versions are m24 and later versions are m22 iirc) but you won't need to as yours will be m22.

cheers fella's your information and assistance is much appreciated.

hi op
i dont want to piss on your parade but surely an m45 is not going to give you any meaningful gains, from some threads i have read on club gti an m45 on a 4cyl vw is not enough to produce any real significant gains.
the recommendations have been to go for an m62 on a vw 1.8 4 cyl, with a 5 pot audi surely you would need at least an m62 to flow enough air to feed a 5 pot?
-
According to Eaton, these are good for vehicles for up to 3.0L the gearing of the pulleys is crucial when you are setting these up. I am hopefully looking to gain a moderate 7psi....I have room to mount another M45 - if disaster strikes...

are turbo/superchargers not rated more by the bhp rather than the engine capacity???
