quaife straight cut box into the nova

Dunno what you mean Chris.
I've done a whopping 5 miles so far this year all under its own steam!!!

well its now fully road legal!!
i took it for mot and discovered the quaife box was not going to be any good as the ratios are just too close and not really letting the turbo build boost and pull hard through the gear, was just spending all the time changing gear!
i could have changed the final drive to a higher ratio but as the quaife 1st is long ratio anyway it would have been like setting off in 2nd all the time if id have done that and the in gear ratios would have still been the same anyway.
so i had a look through the vauxhall gearbox info that stuart has in his sig link and found that the f18 has similar in gear ratios and the same 5th ratio to the f28 but a different final drive and in 5spd and as i dont really want to change to a f28 i thought id get a f18, now the f28 has a 3.72 final drive ratio and thats the same as whats in a f20 4x4 gearbox and luckily i aquired a 3.72 cwp from a f20 4x4 gearbox a while back so i went and got a f18 from the scrappy off a cavalier and removed the cluster from it ready to strip all the gears off it and put them onto my 3.72 pinion shaft

cluster out


strip down




its so much better now it has longer ratios

got some new greenstuff pads put in too


and went for a blast

Looking good Matt, what cwp did it have ?

Is the old gear set for sale as I may know someone after one.

Nice work, stripping the gearset looks a scary task how do you know what you're doing (as Haynes has nothing about it)?

Front looks a little high on that last pic or am I seeing things

hi, the quaife is built back up into a f18 casing and has a 3.94 cwp and std diff, its for sale if you do know someone for it?

thanks

no your not seeing things iain it is slightly higher at the front but thats how i like it as i think it rides and handles better with a bit more travel tbh, gearbox work is all self taught, you dont learn unless you get stuck in

I sooooo need to see this car in the flesh/tin.

I'd be interested to see your times down a quarter mile tbh though

Pm me a price Matthew, I know someone building a nice Xe and he currently has a f28 which I don't think is suitable.
