Title: My engine build - py
Post by: Sknight92 on August 30, 2016, 05:38:09 pm

Evening gents,
I've just had my rebuild complete - over bored to 76.5mm pistons. What cc does that now equate to? Also will standard injectors be good for fuelling after remapping? Can't find g60 injectors anywhere.. Ocd have some injectors but can't find what the standard injectors will fuel up to!
Thanks
Sam

I have 76 mm pistons , god knows what it = too the machine shop told me would be much 😞 But they wouldnt warranty the engine if i didnt get forged ones.
Depends what mods,  you can have a map done by OCD (by rottelle racing) suited for g40 injectors 190-200cc on here people reckon they will happily take up to 160bhp.
OCD ones are for tubo set up 315cc , i have posted in every vag forum going havernt had owt yet.

Hey bud,
Sounds good! Got any photos? I've tried uploading but it won't allow me on my iPhone!
Ocd I find are shit hot, I'll ask them about that when I get my charger back. Moving house has cost me a lot so the car has gone on hold slightly  >:(. I remember reading on here before what each overbore size meant on cylinder capacity but I can't find it now! Someone will know I'm sure ha.

See here for our maps:

Most G40s in the UK running a variant of these.

E-mail me: enquiries@poloperformanceparts.co.uk

And I'll be able to sort you a map to suit out.

Cheers

Pete
