4speed To 6speed

[mikeyboy]

is there any point of buying a BAmkII n/a xr6 and replacing the 4speed with the ZF?

any help appreciated guys.

cheers, mike

Why not just buy a 5SP manual. The T56 is a better box for copping abuse and big power but it might just be a waste of your hard earned in an N/A BA.

Buying an Auto and then doing a manual conversion is going to cost a little bit unless you happen to already have the pats sitting around or you happen to be related to Mal Wood.

Unless you are going to run big power in your N/A, or you are going to absolutely rape the poor thing, the T5 should hold up to the type of power that the N/A puts out.

From what I've heard putting a ZF in a BA is a big and expensive job.. Plus you have to buy the ZF too.. What power are you aiming for in an N/A that require a stronger box? You could get the 4 speed built with all the fruit for less than a new ZF I would think.. Or do you want the ZF just for the fact you have a ZF??

Either way I think its pointless in your sistuation... Just buy the car with the ZF standard..

Can be done, look for my thread "BA to be BF'ed" where I describe the process.

The ZF is a great box, and it physically fits the BA no problem, it is the electronic interface which will cause you the greatest amount of work.

Our cars,(BA and BF) use a CAN Bus communication network, and several modules are linked in this network (BEM, PCM, RCM, Cluster and the TCM in the ZF) and it is not possible to upgrade one of these to BF version (TCM) as the other modules will not recognise the upgraded unit, and refuse to communicate.

I have upgraded my car to complete BF F6 specification, including changing most of the wiring looms and mentioned modules, ignition lock etc.

Cost will depend what you can find a complete upgrade from a donor car for, but you will have by far the least trouble by lifting everything from a BF to you BA.

Once done it works a charm, and I am running 363rwkw through my ZF (FPV F6 unit) with no trouble at all.

Send me a PM if you have specific questions about this.

if you buy a n/a with a 4sp just beef it up. they'll handle what ever a n/a can throw at once they have been done up. theres still quite a few high powered T's with modified 4sp runnin around. or you could just buy a car with a zf box. mine puts up with over 500rwhp all day & its never compained
