[wagvr6 0]

I have been offered a modified head for my vr6(my car is a 95 vr6 it has 3 wires coming from the throttle body which i believe makes it an obd2 ?)

the head is from an obd1 will i be able to swap the head on to my car ?

thanks in advance.

The heads are all the same iirc

3 wire throttle plug is OBD1 mate. OBD2 throttle uses an oval multipin plug.

Heads are the same across all VRs, the only thing that differs is the chain gear. On late AAA engines the upper chain is simplex (single row) and early AAA and ABV use duplex upper chains, but just retain your existing cams etc and you'll be fine.
