I forgot he has a top mount. If 3.5" turbo to tip will fit with a top mount, then it shouldn't be too bad with a bottom mount.

 

Yeah I want better pictures too. I tried. Could not get past the bell housing.

 

Its a really tight fit with my. I cannot remove dp without unbolting driver side engine mount and raise the engine a bit. That 3.5" v-band flange does not come out otherwise...

 

The overlays only reinforce the idea that he should install a 1.6L that doesn't build boost until 5K; especially since he's quite often around 3800 in corners.

 

Got second place at the season’s last race. Also ranked second in my class overall this year. I’m pleased consider all of my problems with the brakes and clutch. I have a fastest car by far in my class. Now I only have to learn to drive it fast

This is how my gearbox sounds like now Time to get new one I guess

I broke it in last superlap session when my cam sensor got loose. Ecu start cutting fuel in full boost and then when it came back it hit all the 300ftlbs+ torque back to gearbox through unspring twin disc clutch. I would been surprised if my gearbox had withstand that

 

Congrats mang!!

 

How easy is it to get another 6-speed in Finland? I hear it is tough in some parts of Europe.

Getting something stronger gets expensive quick.

Good timing breaking it in the last session.

 

I have good salvage yard contacts in UK. 6speed gearboxes cost around 400-600$ in this part of Europe.

When my car started to twitch due fuel cut I knew that I can stop my lap, spare my car and give up my second place or run(all-of-it) it to the end and likely broke something. I’m glad I choose to run it to the end. That move gave me my second place in the season’s final results.

 

That’s on my to-do list as soon as I get new gearbox.

I think my car is the only car in my series that doesn’t have any Dyno tuning on it. All the tuning is done in street at night when there isn’t any traffic

 

I love this car, good work!

I'm jealous you can get gearboxes that cheap too!

 

My 10AE Turbo build should be complete this week, as if I wasn't already super excited after watching your videos I want to drive that bitch right now!

Very nice build. Thanks for sharing.

 

Here’s video from the last race weekend. There’s more in my YouTube channel but this one has most action in it

 

Superlap video where my gearbox broke. Note the cam sensor signal


I found 466$ 6speed gearbox from UK but I don't know when I get it

 

ever think about not downshifting so early?

 

thinking isn't my strong point

And I have to begin downshift early! If you haven’t notice my gearbox is broken. There’s a good change that gear isn’t going in at the first try.

 

This came out with the gearbox oil

 

looks legit lol

 

In for tranny gore

 

Have anyone ever tear down these gearboxes? I mean all the gears work. I guess it’s just the “main shaft gear” etc. that has failed. I’m not sure if 5speed boxes share any same parts...

 

The internal parts of the 6 speeds are the same as the ones in the RX8s. They frankly have a rotten reputation in their racing circles. But in turbo Miata land it is better than our 5 speeds for holding power without breaking. I know a race shop owner with lots of experience with them. Mike at ISC Racing in Florida.
