Zetec turbo
 
Guys in getting a 2.0 Zetec built for more boost, aiming for about 400ish bhp plus nitrous, what gearboxes and axles are you all using for this sort of power? Guessing I may have to go T5 with an atlas or 9"

I'm using a T5 gearbox and Volvo rear axle. An Atlas will do but it needs heavily (and costly) uprating or an 8-inch Ford axle is sutiable but they are getting very rare and the ratios aren't usually ideal for a four-cylinder turbo. A 9-inch is a bit overkill. You will need a dry sump at that kind of power by the way.

Yes mate I'm looking at a dry sump! I just contacted quaife but they want 7k for a gearbox to take that power ha

Sorry what car are you putting the engine in, Gearbox and axle choice will depend a lot on weight grip and tyres used,

my capri just runs a standard mt75 and 2.8 atlas and limo and 215/45/15 toyo proxies with about 290 bhp haven't broke anything yet :DD:

Why do zetec's need dry sumping above 400bhp thought it was revs that killed the oil pumps ??

XRT_si 24-03-2014 06:19 PM

No, nothing to do with revs, there have been plenty of 8000+rpm NA cars with no oil pump failures I'm told from Dunnell, the Zetec specialist.

Generally, much above 400bhp and they are a ticking time bomb seems to be the opinion.

It's going in my ford Anglia, I'm already running a supercharged 1800 Zetec but just need more power, I've heard it's a combo between revs and the extra force the boost is putting down on the crank?
