ba xr6t road to 500+rwkw

Recommended Posts

heya all after running 585 at the wheels through my btr 4 speed I decided its time to get a more serious gearbox and actually get my setup working.

this weekend ive just done a t56 conversion. fitted an xtrreme twin plate, malwood short shifter, malwood heavy duty ally master cylinder and clutch hose. I just gotta change my centre bearing as the donor had a different tailshaft centre bearing.I must say its a very straight forward conversion even in regards to modifying the auto harness for start and reverse lights. the car is due to be tuned in the next coming weeks. expecting around 700-800rwhp on 24-28psi.

well im limited now to my rear housing so the plan is to get a 1.15 ar in the future then more boost. still got 15% in the injectors but I reckon id replace them. its a journal bearing mate



im not to concerned about the high reving its a big motor so 6k is plenty. with a new 1.15ar rear housing and 30+ boost itll prolly go low 900s

The power is there and along with it comes a lot more engine wear. This is the joy of an undersquare engine.


If anyone is interested, look up a piston speed calculator and see what our engines do.

You'll love some extra rpm with the manual. Mine at 6k limiter is sh*t allways smashing it and ends up hitting it at 3/4 track at the drags. I lifted it to 7000rpm at drags and never turned it back would go higher but stock motor so don't wanna get to gready. If I had a built motor in it then it would be set at 8000rpm.. more revs the better.


Any plans to run this at the plex some time? Would be keen to come see how it goes.
