Personally I don't think it looks a mongoose, backbox looks different.

Could be a custom jobie as said, no one truly knows. The previous owner said he bought a mongoose, hower the guy who built my car possibly the king of all things 4 tells me otherwise. :)
 
To save making a new thread (bit pointless, lol)...

Dropped the car off at 7am this morning and got a call at 9am saying it was ready :eek: Well impressed me actually... a gearbox swap in 2 hours.

Went and picked it up, drove it for a bit, thought this is nice and quiet (no input shaft whine) and pulled over to turn the boost up :D

So surprised how much difference the TorSen LSD makes around bends. Powered around quite a sharp corner to hear the tyres let off a massive scream... with the old box it would have just gripped harder and harder.

Still, it's nice to be able to drive the car without being poisoned by the burning oil and the performance increase is superb. Not to mention, the compressor stall now chirps at an even higher pitch and sounds mental!

Just need to get my torsen box rebuilt now and get that back on the car :cool:
 
It needs a new input shaft bearing and 2 new diff bearings, but while it's in bits I'll replace all of the oil seals as a matter of course.

If you replace the standard BMV with a ball and spring controller, you get full boost immediately rather than the standard BMV adjusting the boost the higher the revs.

The standard bearings are caged in a nylon cage which is only spec'd for around 170lb/ft. If you have anything between 10-12psi coming in straight away, you're trying to put close to 200lb/ft through the gearbox and by hammering it in first gear, you'll weaken the bearing cage causing them to either collapse or even worse, shear from the diff itself.

If you go easy on it in 1st but hammer the other gears, you can normally get away with not needing a rebuild for many years... but of course, it's better to do so and get it out of the way. You can get uprated steel caged bearings which don't stress under the extra torque and therefore, are much less prone to failure :)
