ive got my saxo vts booked in to have a tb convertion and was just wondering if i was to have a s1 or s2 rally box put in is it going to be quick over the quater.

yeh this is def the box to go for for acceleration ive heard storys of vts with this gearbox running in early 7.0s to 60

Where have you booked, and what tbs are you going to use. Are you getting bigger injector and a remap or stand alone ecu?

s1 is the shorter box, in theory quicker

cheers bud. what is the difference between the dth ones and is there any bhp to be gained and are the price similar

They are just smaller, as you know there is not alot of room on a vts. By fitting these I can make my life better for running a cold air feed. No performance advantage.

s1 gearbox is not shorter its the common misconception.

the ratios of all pug/cit boxes are the same, xsi,vts,gti,s1,s2 rallyes etc...

its only the final drive which is different due to the crown wheel and pinion shaft. so you could just look around for a final drive and use your vts internals if they are in good nick, also means when rebuilding you can whack an atb in

also dth allow a slightly longer inlect track and so theoretically a wider power band and more midrange

or just use a set of gmc 180 trumpets
