What did you do, google images "homo welder"?

Way to kill it for me.

Tim's going to love the addition to his worklog.

I actually searched "sexy welder", but when that came up I decided it was better.

Thats what they go for alright. You can get T5s for less than 300 bucks plus 400 or so for an adapter. Thats still less than what most miata 6-speeds go for and stronger to boot.

Transmission conversion is common in the GTX/Protege community since mazda FWD and AWD transmissions are glass.

If you can hook up a T5 you can do a T56 right? Why not get you another gear?

T56 is quite a bit bigger. I bet you would have to open up the tunnel quite a bit down by the output shaft.

T56 is huge.

And expensive.

Eh, that's too bad. I'd like another gear but I guess it's not necessary.

In regards to fronting the money, I figured that would be a given, or if nothing else, I would hope to pay for the right to purchase his cad dimensions, ( with a signed non-duplicate Clause in hand, don't want to rip anyone off.) Given the quality of Tim's work, I am willing to bet that it would be well worth the cost.

I :heart: MT.net. OK I'll try to hit it all up:
Yeah that's fine. I will attempt to document it well and not disappear in the future.

It's pretty darn simple. If you can't figure it out on your own, the built in tutorials are pretty good.

I am not sure. There's talk that it's fine as-is for my goals (a few more HP than whatever you make) but I can't seem to find anyone making that power on an internally stock engine. The rods/pistons are the weak link so that's what I'll replace with forgings. I'm still learning how to spec a custom piston.

Stock crank is forged. HLA's so I won't be spinning it to your RPM :(

If someone wants them, sure.

They will be machined here at work, both the adapter plate and the flywheel adapter gizmo. I couldn't afford this otherwise. A 12"x18"x1" plate of aluminum isn't cheap, but I come to find out we have had over 24 feet of 'obsolete' 12" x 1" plate on the shelf for the past 9 years. The flywheel adapter will be made from the cutoffs from our steel upper camshaft pulleys. I am lucky and must take advantage of the opportunities here while I still have the chance.

I can certainly get a cost together once it's all done, if it all works.

haha yeah I think anyone that reads that thread thinks that. She's pretty good. It's definitely the 'kit' to buy if anyone want's to run this V6 with safe power levels/miata drivetrain. Her subframe quote shipped to me from England was slightly cheaper than the V8R subframe.

Making a flywheel/bellhousing adapter for the BP/T5 is doable. The problem is the PPF, driveshaft yolk, and the costs of the donor (mustang?) flywheel/clutch/starter. That will all add to the cost of the trans swap. You could probably find a way to use the miata starter/flywheel/pressureplate with a clutch with a T5 spline, and rig up a way to work throwout bearing. I'm starting from scratch to it's much easier to just use all inexpensive mustang parts.

Because:
I budgeted buying a brand new Ford "T5z" for $1200, and the bellhousing for $155. I can definitely get a used one for cheaper and I may, if I can find one I trust. I do not want to explode a junkyard trans after getting this thing together.

If this all works and someone wanted to copy this drivetrain in the future, I will make everything available to buy or the files available to make it yourself. I do not think there will be much demand so it shouldn't be a problem making another set or two 'on the side' at work.

350-400 can be achieved on stock internals but is the limit of the rods, those with aftermarket rods see north of that but around 500 oiling issues start popping up.

if you want solid lifter search out KLG4 heads from 1998-02 626 KL's they are solid lifters.

I plan to have north of 500. What sort of oiling issues?

iTrader: (6)

You're building a screamer engine that will not make 300wtq, use a Miata 6-speed to save weight and engineering time.

MD323

the rod bearings end up starved for oil at higher loads, here is a good thread about it, some of the fixes suggested and his rebuild: http://forums.probetalk.com/showthre...d+bearing+soup

though a local car made 500 wheel without oiling issues on a precision 6265 with just rods/pistons so it is not a guaranteed death either.

If I recall correctly there was a small displacement version of the KL (1.8 I think), which had a great bore/stroke and rod ratio. Someone tried to build a 9k rpm screamer based on that, but found that the oiling system was ****.

Im sure if you keep the redline not much north of stock it should be fine, regardless of power.

It would probably be worth porting and shimming the oil pump though, Its usually not difficult to do, depending on the pumps design.

MD323

yeah the K8 came in mx3 GS's

the oiling issue can be resolved by downsizing the oil squirters and enlarging the crank oiling ports (i never got that far with my KLZE so forgive me if my details are alittle vague) as well as some have moved to external oil pumps.

Running a miata 6 speed would require me to still fabricate some sort of bell housing and flywheel adapter cause, ya know, the V6 doesn't have the same bellhousing or flywheel flanges as the BP. And the same goes for the starter but I could go the same route that the european people do. I would be able to run the PPF and the torsen, but I don't think that'll last long with the torques I'll hopefully be making

My block doesn't have oil squirters, making it a later block. it does have a forged crank though, that was my only real requirement. I do plan to enlarge the main bearing feed passages. I could also run an external oil pump, there's large ports/plugs on the oil pressure side everywhere.

I used to be an mx6 junkie, back when a KLZE was all the 'rage'. There's some twinT'd making 1000whp - why in a FWD car who knows (dyno queens). Subscribed for V6 destructornator

You gonna use the oem intake manifold with the VRIS?
