BTR 4 Speed

[polishboi.luke]

hey guys just wondering what kind of power have people seen go through these before they go bang? mines been built by bta motorsport and ive just done the engine so I was wondering how far I can go

Depends what bta motorsports put in it. If they just did a standard rebuild, I'd say it's a hand grenade for a modified xr6.

I was looking at one with a BTR that had been built and the main things you need are:

Strengthened (kevlar bands etc), BIIG transmission cooler that bypasses radiator and modification of the shifting so it literally BANGS into every gear (sorta) cause you want the gearshifts to be as fast as possible.

But the price just ain't right for all the work the car needs, thousands and thousands of dollars needed to be spent.

You don't. You want to balance the shift speed to protect both the clutches and the hard parts (especially with a Btr trans) fast hard shifts = happy clutches and sad hard parts, slower shifts - sad clutches and happy hard parts.

Piks of happy hard parts ?

I stand corrected, what you say makes perfect sense.

Iv had 560rwkw going through my btr an never had a drama with it, box was 5 years old as well an I did several  9 second passes with it.  trick to make them last is a good gearbox builder an good tuner, as well as knowing the weakness of the box which is the overdrive fourth gear, never smash it in that gear an always drive it in manual mode.
