Awesome video! I found a forum where this guy posted pictures of his build, but didn't show the actual piece that attaches to the gate piece. I didn't know he made a video, that's great. This video shows how he did the only part I couldn't figure out, and it is simple. So this (#2 option) should be really simple.

I don't think it needs to be that complicated. A bushing/bearing & seal can be pressed into the freeze plug hole...as long as the piece in the screenshot above places the extension concentric with the original shift rod of course. The freeze out plug hole may not be concentric with the shift rod, i didn't digitize the rod on my T5 model.

Something similar.

That looks like a pretty good idea.
If we could use something like the last couple of inches of rubber boot end of the steering rack. Or something like that.

After reading this entire topic I can also confirm here in the UK the Quaife 5 speed gear set is crap. After three years of case bolts shearing which I fixed with 12.9 cap bolts before Quaife now offering them with the gear set, 3 rebuilds I now have a sack of scrap gears all with the case hardened surfaces eaten through across the whole width of each tooth so desipte loving the ratio's I've chucked the towel in and put a six speed NB box and will just have to see how long it lasts which I suspect will be more than the 6k of mainly fast road and 2 to 3 track days a year.

Quaife's response thoughout my ownership has been "we don't warranty race parts" "its normal wear" "its the wrong oil" "Its your builder who's built it wrong" (they have only been building motorsport tranny's and diffs for 55 years) " we have no issues when we tested it" "no other customers have had any issues". They obviously don't do much customer research but did say they had lots of spare parts in stock lets hope they end up keeping them for a long time.

Bottom line Quaife are trading on a reputation they don't deserve and understand why FM gave up on them and are looking at developing their own offering.

Save your $$$.

Interesting anecdote. I was putting money aside for a stronger gearset from them as they offer transmissions that hold 700hp for Vipers...I wanted to see if they could make a similar strength set of gears to place into their NB case.

Anybody else have experience with Quaife?

The general consensus in the miata world is that they are not worth the time or money. FM used to sell them and were not happy with them so they dropped them. There have been several members in here who have had issues. Using 6 speeds as consumerables until TSE gets their trans swap kit out someday is really the only solution right now.

If your going to be spending $$$$ on a gear set that doesnt even work why not spend that same money on a good shop to figure out an adapter plate/clutch pairing for something like a t56 or cd009 (cd009 are dirt cheap commonly swapped on MANY platforms and are known to handle up to 1000whp at times) to the car or the TSE setup that they are working on?

This post needs to be stickied. The more time goes by, the more frequently I have to give this speech to customers calling in telling me about their 250+whp build with a stock 5 speed. "What do you mean it will break?". Gahh

Well, as of right now I have a Turbo II RX7 5 speed sitting in my garage.

My best hope was that I could have a driveshaft and axles made to get the ford 8.8 into my car and hope the RX7 trans holds up to the power. People seem to have a lot better luck with those than the 6spd I have in my MSM. That's only staying in my car long enough to break my motor in these next few weeks.

someone is selling a TII rear ended swap and subframe right now. TII trans are strong as hell, I have 400hp a 2300lb car and 245-17s on the car and it spins those and holds up to the abuse no problem.

That's good to hear! I'm shooting for 500+, where I land remains to be seen.

When it comes to rear end why not just do a monster Miata 7.5 or 8.8

then you also have a unlimited choice of gearing pretty much and replacement parts are common and cheap

I think I only paid like a grand for my whole setup with axles, subframe, 7.5 with a true trac in it ect.

Generally we are not breaking the rear-ends so no real reason to change them out. Occasionally axles will break if you drag race and get real hop, on a road corse if you hit the curbs hard you could possibly crack the carrier arms. At this point it is just the trans that is the weak link in the drive train.

The 8.8 from the Cobra is exactly what I'm using. Not taking any chances!

They're heavy and have shitty LSD options. Both have an expensive aftermarket torsen option or a crappy open clutch pack, and the 8.8 has the geeken option which aint that great either.

well if you plan on blowing apart the stock one on wastegate let alone turning it up then it's hard to beat the cheapness/local parts if needed/unlimited gear ratio choices.

Im talking more to like the person above looking for 500+ ect.

Do you know that? People used to think normal torsens were no good past 350 and we've got people running them with drag style starts with hp numbers that start with a 4 without issue.
