Quick question,is a 5speed hawkeye gearbox stronger than a blobeye one? And if so how much extra power can it take?

Pretty sure theyre the same
TY754
Good for 400 bhp I'd say

they are the same - TY754 box is good for 400bhp, but clutch struggles at 350+

the classic one is TY752 and is weaker

Would a blob wrx be a straight fit for a late uk classic? If I had the matching diff

Tidgy

hawkeye wrx box has same casing but slightly different internals, i asked those in the know the same question

So they are a little bit stronger then? Might look into costs of them.as I'm running 350bhp on my blob one an would rather swap it whilst its running good and before i up my power to 380/90.so it doesnt go bang and I can sell it on for a few hundred quid.

Are the gear ratios the same on the blob an hawk boxes then? I presume they are?

Tidgy

not sure, they may well be different, hawk went to 2.5 dont forget

If you're talking blob wrx vs blob sti gearbox then no, they're not the same

You want the 6 speed sti box if you're after strength

Tidgy

no blob wrx vs hawk wrx, both 5 speed

That's what I'm thinking 2.5 may have had slightly different a ratios to accommodate for difference in torque etc will have to have a look into it now

jake1989

Not a straight swap,clutch forks,slave cylinders etc are all different,plus the 5th gear ratio is longer on the hawk box.lot of work for a small difference.not worth the hassle

Your WRX box should be ok if your not planning on launching it and exercise some mechanical sympathy, but if your planning on caning it then you need a 6 speed.

Really? One of the mechanics on our club forum said it was longer.still a lot of hassle though for minimum gains really.

WRX 5th is slightly longer than 6th ( 0.756 ) in the STI sixspeed.
Agree, wouldn't change unless you had to.

My uk my00 classic box in on it last legs I think, I'm not looking for power so don't think I need a 6speed. Should I look at newage wrx boxes as they tend to have less miles, anyone know if they fit? Most subaru parts seem to be the same across the models
