Hi ,

 

I was driving my supra home going about 50mph and i herd a whining noise within 3 seconds i smelled like a rotten egg smell then 3 seconds after that it was like a machine gun had just gone off, I can start the car as long and rev the engine when the clutch pedal is in the moment i take the foot of the clutch pedal its like a major rattle any ideas what this could be ??

 

I drive a twin turbo full BPU manual 5 speed box though :s , anyway it resulting in thissupra broken.jpg

 

cheers.

It may have done, I don't dispute that.

 

However, my NA-TT BPU on a W58 has been this way for at least 5 years, and hasn't crapped itself.

If you drive it like a mans appendage doing hard launches, harsh down shifts and the like, the eventually, yes it will poop itself.

 

However, it is not a recipe for disaster. Treat it right, and it will last, just like mine has.

Good time to start seeking a R154 if you dont want to shell out for a 6 speed.

R154 far superior box, very strong, holds good power.....there is one on here for sale, but a few other bits are needed for the full 100% conversion.

See Post 12.

 

I'm not disputing that it may be the box has crapped itself, just disagreeing with the "recipe for disaster" comment.

 

Well you must drive like miss daisy or your car is making nowhere near the power you think it is, my bro got through 3 w58`s in just over a year on a 1jz bpu, he`s now using a 154 and single turbo with no real issues and thats for trackdays too.

If your looking to use your car to its full potential then I'd go with a r154 if your box has failed. I just so happen to have one for sale too ;)

 

How much you selling for ?

 

could sombody comment on if i was looking to get a 6 speed what parts do you need different to what i already have in the 5 speed /

 

thank you

I doubt listy drives like Miss daisy, someone else I know is at BPU on a W58 has been for about a year and he drives it lets say rather hard box is still in one piece, depends on the clutch you are using depends on the condition of the box before it was mounted up to a TT engine

Really you'll need the box about 2-2.5k second hand for a good one, prop, and a 6 speed diff (if you haven't got one already) as the 5 speed diff will mean you be at very high rpm even in 6th gear for motorway speeds on a V160/V161

 

Oh and to the op, if you can put it into gear it sounds to me like the clutch has gone tbh.

I'm only running 1bar at the moment to try and help it last until I source an R154 ;)

 

I don't do silly launches or harsh downshifts and the like. If that means I drive like miss daisy, then I guess I do in your eyes. Those who have met me can however confirm, that I don't ;)

 

Plus, your brother tracks his Supra does he not? Anyone who drives on the road as if they are on a track (to give the same treatment to the box) shouldn't be on the road imo. Therefore, Little Num destroying 3 boxes at BPU and mine lasting, is incomparable really.
