rd28 to td42 engine conversion tacho wiring

[jedskipow]

We did same and only drama was glow plug light flashing. I think it was Tried sticking 2.8 tacho sender in 4.2 hole but ended up using 4.2 sender of right length. Just cut or unplugged wires off 2.8 and extended or fitted to appropriatte places 4.2. You aren't really doing 180kms/hr. Diffs are different. Changed yokes. I should change centres.

My mechanic is doing a very very worked td 42 turbo into a GU with blown 2.8 at the monent.

He is looking for 6k plus revs from the 4.2 and given the way his old GQ td42 goes I don't doubt he will more than achieve it. Soon be more trophies in his office I guess.

I would luv to get him to do my td4.2 in my GQ but given the cost and the way mine runs after he got thru with mine its a little hard to justify to the boss.
