does anyone know roughly the max power a T5 5 speed gearbox can handle ? p.s. in an EF 4.0 litre.

Heaps! It's the abuse that kills them to a point...

I've heard up to 450hp, but agree with ebxr8240 that giving it a hard time will shorten it's life (right Laminge?

).

Well, not being an expert here (uhumm, clearing throat) I can verify that clutch and T5 in an XR8 can take a full 207kW at the rear wheels. However, it's the torque that kills them and mine is coping well with 550+Nm. However, if you subject your gearbox to shock loadings (like banging the clutch in at gearchanges with W.O.T.) especially in second gear, expect breakages.

I suggest regular oil changes using a high quality ATF (auto trans fluid), even synthetic.

Yes gearbox oil,hypoid is too thick for t5's...
And most Jap box's too,use engine oil...
Some times hypoid is put in by mistake on service...

Well... if you drive sedatly, they dont have a problem... but if you have over 150rwkw and go to the drags regularly... they die very quickly.

Been there! Hypoid oil is too thick the syncro's won't work in cold weather,wears out syncros and needle bearing if too.
Ford U.S say ATF and a friction additive.Or synthetic auto trans fluid which is thin!!
