Daz, call Stephen at Engines Plus in Melbourne�],he can tell you which sump has a rear pickup. SR20 was fitted to Pulsar also,he might supply the front cut as well. I have lost count of the number of their engines i have fitted,so mention my name and you might get trade rates. Pick and payless at Blacktown has 5,000 cars and you can browse all day taking measuements. Driveshaft off 265 has 2" dia with three large unis, i modified one for mine. 164 diff might be stronger and bolt right in. A friend of mine is just finishing off a Honda S600 drag car with solid 9" diff, superchared fiat engine, it is beautiful,so nothing is impossible it just takes a little longer to do. I have spare long booster pod you can have if needed. Go for it and have a CB radio on the truckies channel so you know where the fuzz is. Regards Jack McIntyre.
