ABF turbo

hey hey.. im after some info on my new perchace.. or should i say.. freebry..

i have just taken delivey of a 2.0 litre twin cam abf lump.. all in bits..

it was removed from a seat ibiza GTI a while back and stripped..

the head has been ported and polished,

re ground, polished and balanced crank.

blue top cozzie injectors,

audi s2 5 branch manifold, (the porche desighns one ) with one branch ground off and a throttle body welded in its place..

all valves polished.. all work carried out by cambs rebors



basicly.. im drivin a mk3 golf 8v.. and im wondering if the abf head will go strate in my 8 v block???

are the comresion ratios ect the same ??

any info gratefully recived..

thankyou james

that mk3 on your drive yours then mate

May i ask why you would want to fit the 16v head to the 8v block when you say the 16v block has been reconditioned aswell?

How much of the engine do you have?

i have what i belive to be the complete engine, howerver it is in bits..

the 16v block has had no work done..

its the conponants that have been reconed..

this is why i would loke to use my block with the new head..

it would just save alot of time changing just the head, and not having to rebuild the whole engine..

can this be done mate.?

I've not heard of this being done before mate so i could'nt say for sure.

Have you got the abf loom?

hay james, think you'd be better off re building whole engine (sorry) I think compression ratio would be too low with 8v block and dont think it could be done anyway.

The head from what I can remember does fit, but why would you fit it to an 8v?
There are things in the 8v that are not needed, like the aux shaft, depending on which 8v block you have, some dont have the oil sprays under the pistons which are fairly important.

Rebuild the ABF, long term your best and cheapest option.

ok.. thanks for all your adcvice..

i thought it was a long shot but worth askin..

i will rebuild the abf from scrach.. atleas that way i can use the new crank and lightened flywheel n clutch ect..

thanks peeps.. il let you no how i get on..

it should be quite a pokey little lump.. it runs 150 horse standard so with all the other bits fingers crossed should be lookin at around 180 brake i recon????

Rite.. The ABF is being built very soon..

However I am going to turbo it.

Does any one no were I could get new head bolts and gasket kits from.? Or should I go direct to VW?

Has any one done this befor.?


Cheers, james

What compression ratio are you planning?

arp bolts i should think james, gasket will depend on compression i would of thot, prob loads of peeps have done before, its all on the net

I'm unsure of any compression ratios.. I'm yet to research it.

Iv been tOld using two head gaskets may be ok.. Or make a spacer/ shim type thing to lower the compression ..?

Iv also been thinking wether to run twin 40 webbers or injectors.? I hear the ABF runs well on twin carbs.?

Any ideas peeps

dont run 2 head gaskets it will last 5 minutes and a decomp spacer/shim will probably last another 10. Do it properly by having the combustion chambers enlarged or if they are flat heads(i cant remember now) then you need to get the correct pistons for the compression ratio. Twin webbers with a turbo will be crap you will need a sealed plenum for them to get the boost, horrible to setup and really inefficient. You will need some sort of aftermarket management.

^pretty much summed it up

pistons giving roughly 8.5:1 woulbe about right. no point decking stock pistons really, unless you plan on running like 3psi or some s**t

carbs and a turbo is a horrible setup to get right. its really difficult to stop it being rich off boost, and lean on boost.

If you cant afford aftermarket managment, you can use g60 management reasonably easily, though maybe with a rising rate fpr

Well that's defiantly food for thought..

Scratch the carb idea me thinks. What injectors do you guys recommend..?

Iv been told cossie blue top injectors will run it.. But guy reckons they are too large.?

This is all new to me.. Iv swapped engine but only ever built them at college..

Cheers for all your ideas.

i had 2wd sierra cosworth yellows in a series 1 rs turbo running aftermarket management all forged bottom end, massively specced up cossie turbo etc etc made 320bhp on the rollers(out of a 1640cc) and they were at 70% duty cycle so not overly stressed really. I would think yellows would be fine for your application but going one size bigger wont hurt as the mapper will be able to make them work fine if they know what they are doing just lower opening times etc etc.

Buff, look at Bahn Brenner Motorsport or AME Racing.....these guys have built 16v turbos, crazy motors mate!!

Ali Ali aLi.. Didn't expect to see you on here mate. I hope it feels good rockin VAG.. Il have a look mate

did you still want this turbo and stuff ??????
