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.? Laughing

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.

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. lol!

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.
