could i but g60 head up onto my 2.0 8v bottom end :evil:

why bother.. if your looking at the 8v modified without the charger as in previous posts, look at getting a x-flow head off a mk4 and run itb's

Those electric "superchargers" slow your car down if anything.

Charged 8v engine (which will need work done to take charger) 160-180bhp

Charged VR6 engine (that can have it bolted on, no internal worked needed) 250-300bhp (and a better sound)

not true mike, the only realistic 8v we have to go off is the one that was built by alldubs for boxman.. this was a load of bullsh!t.. he was running lowered compression with a standard pulley which was not needed, running a standard ecu which causes major issues as it cant handle boost, running 440cc injectors which were overkill and running an m45 like myself.. which is as you say only suitable up to 180-200 brake.. the turbo boys out in america are hitting 300 brake on standard internals and an m62/m90 application should be able to provide the boost levels required to see high power..

Boxmans car is quoted as seeing 10psi on a standard pulley, this is bollucks, the 10psi is a backfill of pressure as the head on the 8v chokes at 5k and thus the boost builds up.. the issues with the conversion to see bigger power mean sorting out the exhaust manifold and the head.. a decent flowing head and manifold will open up the car to seeing much better power.

Discussions with nando recently have seen 8v testing also seeing much better power from a decent cam setup.. so if your really keen on doing the conversion to see big power i would say..

start with a minimum of an m62 if you want over 200 brake.. look to have your head ported and pick up a cam, not too lairy though as boosted applications dont like them.. anything over 5psi will require the compression lowering.. to do this you can run stacked headgaskets.. before people kick off about this.. wolf aka Toyotec is seeing big numbers on his valver on stacked hg's and has had no issues.. he even run the same headbolts as he removed.

hope this helps.. btw i am in the middle of doing this conversion, my car is going down to nando the end of the month to have the brackets fabbed up to fit the eaton..

any questions please fire away with regards the eaton conversion...

Sorry guys, to back-track a shade...

Are the VR/16v exhausts the same diameter?

If so, would I notice any gain running a 16v/VR exhaust on my 8v (once adapted)?

yo im doing a 16v engine conversion from a mk3 16v with abs, and putting into a 1.4 without any abs, and wandering how hard a job it is moving it all over, or can it just be disconnected and would that be easier? james.

Can I point out that for converting a mk3 to use a hydro clutch all that is needed is the clutch cylinder and the white clip that fits on the back of the pedal? As well as ofcourse the pipe that runs to the brake fluid reservoir.

No need to change pedal box over.

Indeed all mk3 pedal boxes are the same, just need the master and slave cylinders + lines and clips as said above :)

Also worth mentioning is the 02j box from a 1.8t mk4 will bolt straight into a mk3

and here is a link to a wiring guide, its based on a mk2 but its the same fuse box on a mk3 so its pretty much the same. Theres a pin which might be slightly different but I forget which one, its mentioned on page 3 of the thread

Digging this one back up but i just saw the above quote

If i had the MK4 with all parts could i take the clutch parts from that and add it to the mk3?
