Its not bhp that damages engines its torque. Fitting very wide wheels, uprated clutches etc will reduce box life.

Its probably cheaper and easier to get through a couple of f20's than to deal with the f28.

I think a fair few people use f20's on standard let's without many probs.

The '20' in F20 means that it can deal with 200lb/ft of torque, and thats roughly what the standard let produces.

Motorway miles are fine, its standing starts and hard use that will kill them.

Any an f28 doesn't weigh as much as a passenger more than a f20!

Its about 20kg more I think.... thats one small passenger!

my mates astra turbo running 280bhp went through 3 f20 gearboxes. must just be to do with howe good the box is initially, or how hard its drove, hey beardy thought u might of had a play on the motorway coming back from pv show? i was rather dissapointed that u didnt wanna race!:(:thumbs: i thought an f20 could cope with 250bhp? but anymore and u need the f28? i stand to be corrected though!

some people ive spoke to say an F20 will cope with the LET engine, plus the F28 will be a bitch to fit in an 8v corsa & weighs as much more as an extra passenger compared to the F20

u want an f28 in a turbo, it will shread an f20

btw what size alloys you on beardy?? the above will be running on 15's

how about for a 2ltr 16v turbo with LSD, F20 box with 5 gear changed to a cav 4x4 final drive (the 6th gear), if possible??

never :D

0-60 - 7'ish (i can sit at the side of a type R)
0-100 is really the same as 1/4 mile as most 2lt corsa will do the 1/4 at around 95mph'ish so low 15's to high 14's(is cars stripedout)
top end 135'ish

my estimates would say corb is bout correct ;)

0-60 around 7.5
so 0-100 around 12/13
1/4 mile about 15.5
and top end you're looking about 135ish

all estimates straight from the top o' me head!

Yeah just hoping people with the conversion done would be able to tell me.

hard to say really imo
as the corsa is lighter than the cavs,vecs etc theyre in

So almost of standard I would like to know what kinda speed figures I should be getting, when I first get it only planning on induction and stainless system.

I know they are around 156BHP as standard but whats the 0-60 / 0-100 / 1/4 mile times / Top speed??

Cheers,
Sean.
