Gearbox Broke


Recommended Posts

Posted

Yesterday at the end of a great mapping session with Jolly Green Monster my gearbox went bang at about ***MPH. Initially lost 5th then could only get in to 2nd, which is the gear I had to drive home in.

So, I desparately need another RA gearbox (without DCCD).

Any help or recommendations would be greatly appreciated.

Regards

Dean wouldn't it be better to get a uprated gear set for yours or a six speed as with the amount of power your car is producing it's gonna break gearbox's all the time

Yeah really sorry about that Dean..  she was flipping flying though.. that set up seemed to love timing..  shame the box didn't..  I could understand 3rd..  but 5th!  lots of torque!

I am about to ring someone who might have one.. 

It would be worth considering an uprated one as mentioned but obviously won't get the car back up and running for the events you have planned.

I have ordered a replacement gearset from Zen Performce. They were very helpful, and taking their advice, I have gone for a modified version of the PPG 5 speed, helical cut synchro engagement box, which I believe is rated at 550 LBS/FT Torque.

They expect to have the parts within 1 week, and will do the work straight away, so at the moment I am still hopeful (albeit reservedly) that the car will be ready for the 24th and 25th of November.

I suppose I should change the clutch at the same time.

Whilst it is disapointing that the box gave up the ghost, as JGM says, "she was flipping flying" even though the MAF sensor was maxing out at only 1.2 Bar Boost. 

Still, had some good news, my new steering wheel turned up.

Glad you got a new one sorted out Dean. Was a shame our Gearbox depatment at work has just closed down or they could have rebiult your old one

What do you mean "if it holds together long enough"

The 1-4 gearset cost £2228 alone. By the time you add a new 5th gear, ancilleries, oil, and labour, I'd be suprised if I get any change from £3k.

So the gearbox better hold up.

Don't know about the rest of the car though.

Lol thats true [:D]

Never mind with the new clutch as well the diffs will be the next weak point lol [:)]

And the drive shafts & prop shaft [:P]

Lol already done the research for the carbon fibre one already  [:(]

My thoughts exactly.

If it gets within sight of 400/400 i'd be pleasantly supprised. 

Although I wouldn't be unhappy with 350/350.

If it's back together in time, we'll see how it gets on at Goodwood on the 24th and PE on the 25th. 

I'll keep those of you that are interested informed, and see you at the next meet.

For those of you that are not interested, i'll see you at the next meet.

I reckon it will be about 360BHP and 345Lb/ft torque???

Any more guesses??

Shall we start a new thread on the subject??

PMSL [:)] Maybe open a book [:D] I'll have 360BHP and 350Lb/ft torque [:D]

And I was thinking of lowering my estimate to 330 / 330. We only managed to get 1 map down @ 1.2 Bar boost, as the MAF sensor maxed out. That was going to be the lowest setting of the 3 boost settings planned. 1.4 Bar and 1.7 Bar were considered for the other settings.

Anyway, it's an old (11 years) RA, out of puff over 100 MPH. (note even bigger excuses)

I now need to source a 300ZX TT MAF from somewhere.
