Fingers crossed it will all be good, but I would have liked the TH700, but KISS Keep it simple stupid is the plan I'm following
Mate Ive got this conversion in a FC wagon with a worked 179... To be honest i would rather have a 4speed manual.. The auto dont go that good with the worked moter.. Cheers

Is that the TH700 you have in the FC wagon, we put the trimatic in not wanting it to be a speedster just a bit lumpy for cruising and sounding good on idle haha,, things may change down the line but my wife wanted it to sound hot, couldn't afford to do it right with a V8 conversion so settled for the hot 6 at this stage, see how it goes and might drop the cam back in specs if its not what was wanted because the guys that did this TH700 conversion said a lower spec cam will get it going really well and they said the xu-1 cam will not have the performance we are looking for but we are just after it to sound really nice on idle and cruise along nicely not really a full power house car,,, see what happens, I reinforced the crossmember to take a V8 if things change down the track
Thanks

Oh thats a shame if you have the TH700 and don't like it, I would have thought it would have been really good with the extra 4th gear
Thanks

I should add that having driven the FC of mini's it really needs a bigger stall converter. PM Lynchpin on here his is Harko's old wagon and he's really happy with it. it all comes down to setting everything up to suit, whereas what mini has could do with some sorting and I think would be good.

Thanks for the article, I am looking to do this to my ute after yet another fail with the Traumatic ... but is there any chance of scanning in the missing page/s? (steps 10 - 15)

Also, having had this on the road for a while now (I'm assuming??) has it proven reliable? Any towing???

Cheers

Doug

Has anyone else done this conversion and did you use a bigger tunnel or was the AUTO bodyshell tunnel big enough?

Yes mate I have done this conversion with a small block chev.

I grafted in a auto tunnel and braced it on the underneath side tying in the floor cross braces. The turbo 700 fits in no problems. The original auto hump has the brace inside so has a bit more room.

When you're faced with an unpleasant task that you really don't want to do, sometimes you just have to dig deep down inside and somehow find the patience to wait for someone else to do it for you.

Fair enough , was going off your signature which mentioned a hot 202 .........

I'd stay with the VP's 28-spline BW78 for a "mostly-cruiser-occasionally-thrashed" car. They will handle a considerable beating, and are lighter than the 9". Easy to upgrade to 31 splines if it becomes a "mostly-thrashed-occasionaly cruiser". LSD centres easy enough to buy. VP brakes are easy to service and parts readily available.

The earlier BW75 is a little flimsy (Number 1 Son managed to put some interesting curves into the splines in his VL).
