Title: VR6 OBD2 TO OBD1
Post by: TORNADO-GTi on 16 December 2012, 18:49

Ive been offered an obd2 vr6 engine without any ancillaries for a very good price, would fitting obd1 throttle body, loom and ecu work or are the actual engines obd1 and obd2 different??

Block and head are are interchangeable between OBD 1 and OBD2

I do remember reading that they are different and not so easy to swap over.

Likes of fuel rail ect.

Basically swap everything over. You can only use the head and block.

so if it is just head and block then its a case of finding all the obd1 bits. is there a list any where of what parts are needed for a vr6 conversion ive looked everywhere with varying answers? i know i need engine, gearbox, ecu, loom, hydraulic clutch parts, exhaust system, speedo.....
i know everyone will say dont build what you can buy but i spent 7 months rebuilding my gti and want a little bit more power now as ive got used to over 200bhp in my tt and 115 feels a bit slow.

Would I be right in thinking an obd1 head would have a hole for the dizzy?

There were dizzy and coilpack OBD1 engines. OBD2 were coilpack only.
