ei guys also wanna ask u all
now im using the bp180 with the original tx3 1.8 gearbox
wanna look for a 2.0litre gearbox i think from a 626 or something?
cause i dont think the 1.8 original one can take the power?
anyone got any for sale?
when i boost on 1st and 2nd gear, rev spikes
Fions,
TX3 gearbox is a short ratio gearbox, and the housing everything is fit perfectly for the B8 engine. This short ratio gearbox will give better pickup. Where the 2.0 gearbox is a longer ratio gearbox it will give you better high speed.
It depends what are the feeling you are looking at, as I am enjoy short burst not top speed, so my TX3 gearbox is fine with me, perhaps if you want something in between you may consider change the ratio, but remember must get an experienced mechanics to do it.
About power, it depends what are the power your are looking at, if your consider 300whp and above than look for ratio changes instead of gearbox change. If you are looking ofr less than 300whp, your TX3 gearbox will do the job, also depending how you monouver it.
When you talking of rev spikes, it definately will not caused by ur gearbox, the spikes u refer to issit boost spikes or rev cuts?
any doubt please feel free to ask
