Yeah they are harsh
Well I obtained the f28 box from browney (cheers mate) and on the way home did a slight detour to collect a wing for danny sp so will get pics up and get this grafted on shortly :thumb:
Just read about the box, was going to say just lob on another F20 and grab another for when it blows again! lol
I killed mine in my old silk violet when going from 4th to 5th, but i was doing about 142mph @ 7300rpm.. so maybe i should of changed to 5th sooner! lol lol
What your thinking behind the F28 then, is the FD closer to 4.0 then the F20?
As surly the F20 would be better ratios no??
Scott
The ratios are pretty much the same (see below) and im putting it on because im looking to max the engines power over the winter (hoping 275bhp plus) and the rumour is the F28's are stronger than the f20's.Quote:

well done gareth you did god job of that one lol
f20's aren't worth a light!
Well I guess if your going to smash a box may aswell do it right lol :thumb:
F28 is a bad idea imo - its the revs that kill the F20 - so I would imagine that the F28 wont be too happy either (although they are stronger I guess) Its the torque that kills F20s on LETs etc....
However your biggest prob is weight - they are about 30% heavier than an F20 - I wouldve saved up for an SCCR if I were you....
TBH will the price I got the f28 for was peanuts so its worth a shot. And in imy calculations with weight saving of the engine and engine bay the added weight from the f28 would probably equal it to a standard c20xe engine anyway. Failing that its going on another diet so im looking to loose about 20-30kg's off the car anyway. As for the torque im only running around 200ft lbs so im sure an f28 can cope. :thumb:Quote:

F20 relates to the 200ft/LB of torque it can handle & F28 is 280ft/LB respectively.
