by the way, looking at your pressure plate i can say with 100% confidence that it is exedy oem replacement pressure plate. you need something beefier if you ever want to go over 200whp.

no that's a real SPEC PP.

not if you have a ceramic disc :fawk:

i still wouldnt use it :) act ftw!

If only everyone could express their advice in a coherent and civilized manner like that, this thread would get somewhere! We're definitely welding together something for my wastegate this week, and I need to program the LC1 soon so I can output to my analogue A/F gauge. Anyone have experience with that? I couldn't figure out how to get it to output properly to the MegaSquirt.

Besides the couplers that I already replaced, what else do you think needs to be changed with regards to my piping?

Good for you, mine works perfectly and doesn't slip at all (unless I really try to make it, which I don't). And my pressure plate is a real Spec pressure plate as Braineack pointed out.

cardriverx - I'm going to drive it around in a few minutes and find out some (nearly) exact numbers for you. It gets up to full boost much faster than you (and I) would expect! Your turbo sounds very interesting, I'd like to see a picture of your compressor housing if you have one.

Best pic I have is this ( you can see the vac line going from the TB to the BOV.) Its pretty nice actually, works great, sounds good, a nice pshhh.

I seem to get 14 psi by 4000 rpm ish.



Man the more I think about making the waste gate dump separate the more I wanna do it.

Nope... my SpecStgII has been flawless since I torqued the PP bolts evenly to the flywheel. I'm currently running 15psi via EBC and it clamps like a champ. I'm gonna say in the 220whp neighborhood. I know what 200whp feels like in the car and it's considerably faster now.

Spec uses the Exedy PP's and then modify's them for their application.

I'll be dragging it at the end of the month and will report back. But a full day of autocross school... probably 30runs with about 8 back-to-back at the end of the day with ZERO issues.

i heard pretty bad things about those clutches on numerous occasions and thats where im basing my judgment from :)

i melted a whole buncha shit under my first miatas hood and my downpipe and everything was welded shut. so if i did it with a complete downpipe, ur going to do it without one...

good luck to you,

anyone who can build a turbo kit for a car, get it running, and not blow the fucker up, is legit, untill that is,, he blows it up

cardriverx - Sorry it took so long to do this, my RL brake caliper sprung a (thankfully well-timed) leak from the parking brake assembly (this spot) for the second time.

Anyway, on the highway in 5th I made 11psi at around 3,200 RPM. It builds boost really quickly after shifts when driving spiritedly.

I'm now running a 3" downpipe + cat to a 2 1/4 Borla muffler. It's nearly silent at idle (which is pleasant). The wastegate now dumps a few feet down from my turbo under the car and sounds excellent (I'll post pictures/video when I get a chance).

Still not a single problem and approaching 1k miles.

Here's some pictures of my new exhaust:

Ok ok ok... I did end up melting my dipstick handle.

very nicee. You get slightly quicker spool than me, but I have a smaller exhaust. I seriously have to copy your wastegate idea..

now that's more like it :)

Found your vid on youtube, it looks like this car runs very well.

More boost, then more videos!

FWIW, I ran Home Depot couplers on my first Miata for over 30k miles including a 5k mile road trip with no issues.

NOOOO bullshit.. I saw that coming. Seriously, when I saw the open WG port and the unmolested dipstick handle.. I knew it was facing certain death!! :bowrofl:

Btw, I LOVE the color of your car. Very nice!

SPEC Stage III FTMFW.

Have over 10k on that clutch. Broke it in properly, and it'll handle a 7200rpm dump on R-Comps. I've autocrossed the shit out of that car, with that clutch, dumping the shit out of it every start. ;)

Put 60,000 miles on a Spec Stage III in my 1997 WS6 T/A. Easily had over 200 5000rpm dumps on ET Drags without failure. The 10 bolt rear end on the other hand...

New video!

And more where that came from.

The cars a huge handful, but extremely rewarding :-P
Its biggest problem is that its riding on my 2 season old BFG Geforce KDWs. Otherwise, John's Tein springs are really not aggressive at all (as you can see form the body roll, how much it squats, and the way I'm pinning the nose with the brake)... and I think replacing those with something stiffer and/or sway bars are in order.
Or really, its great the way it is! Just needs the alignment dialed in I'd say.

Dude, DAMN!!!!!

That car looks like a handfull! :D

I want an auto-x course that long!! I can't use thrid gear on any of ours hardly ever. :(

I put it on YouTube for you n00bz



Also, in case anyone is wondering, that is Devens Air Force Base in Ayer, MA.
