Hi All,

Just wondered if anyone here in the UK is using these? getting good feedback on NASIOC... Seems like a VERY cheap option if they actually work, one guy is running 750bhp (650NM Torque) through it with no problems yet

Can't see it helping much when it's the gears that strip.

 

People in the know inform me that the cases flex, I dont know what the affect is.

 

Yeah this is what I have been reading about online... Maybe it is the flexing that causes the gears to strip?

 

I guess potentially it could force the input and output/layshaft apart, which would mean the gears aren't meshing properly. Which could as Sam said, lead to stripping the teeth off the gears. Though having never seen the guts of a nackered 5 speed, that's complete guess work.

 

These are the internals of my knackered 5 speed with stripped 3rd gear that I'm in the process of replacing. It's pretty messy.

 

$400 plus shipping and duty.......

Seems an awful lot of money for a couple of bits of metal that you bolt to the side of your gearbox.
I doubt very much they are quite as 'marvellous' as they're made out to be.
If they really were so effective then some of the big tuners in this country would be selling them.
By the time you've got them fitted I'd bet you'd be over half way to buying a 6 speed.

 

I have and use these on a 4.11 5 speed from the 2000 RS 2.5
The biggest issue with the 5 speed is that it is a butterfly design case. So under load it flexes outwards. This can allow the gears to move around which in turns causes the above picture. (or extreme amount of torque dumped all at once)

This simply eliminates the cases ability to flex.
And you can install them yourself. Well as long as you can remove your tranny.

 

If you think about it as probably costing £400 GBP total landed then that is literally 1/4 price of a 6 speed... however IF they don't work then £400 wasted is a lot of money! Tempted to try it out...

 

Yeah that's the sort of damage i'd expect to see if the gear mesh had gone. Did a similar thing to an RC car once when the engine mount slipped (that was with plastic gears), ran fine when everything was meshing properly but when you lose that it just shreds the teeth.

Still not entirely convinced on those plates though. Can't see how the gearbox casing would flex at that point.

 

6 speed prices are on the way down. I've seen a few sell for little over a grand lately. Admittedly not late DCCD boxes but still 6 speeders.

 

What power/torque areyou running though

 

Having just read all of the material linked to on NASIOC, I'm not fully convinced.
All evidence, for or against, just seems to be anecdotal at present.
I'd love for it to be proven to work and I'd buy one in an instant if that were the case.

 

I'm getting these fitted to my 5 speed soon, running 2.1 stroker engine, (when it's built) I'll keep you all updated
