So my local forum is basically dead and i wanted to continue a build thread somewhere so here it is.

Just a little background on my car. Iv had it since January 09. it lived life as a street car for a few years and in the last couple of years its become a Friday car/track car.

Here is how it looked a few months into owning it.




And more current pictures

for posterity.

this was at blacktrax where the car gets tunes. this dyno reads super low.



same setup different dyno 2 months later





Then i added cams




or about 180 on a dynojet

T, what the heck happened to NCR? I moved and got super busy with house projects and by the time I got working on my track car again the forum was a ghost town. What gives?

Anyway, cool build. I didn't get a chance to say hi at Miatas at Laguna Seca. I'm going to try to get my MS2 in the car soon and get my turbo working properly so I can have fun at the track again.

Hope to see you out there.

Hey Andy!

I think most of the usual posters on NCR moved onto different platforms. id love to jump start it back up but its probably not going to happen. Ill be at laguna so, Stop by and say hi!

I haven't seen too many pictures of a Wilwood 1 inch master installed. This is the good-win kit and i wish i did it a long time. One of my favorite recent mods paired with torque rt-700 fluid its almost like im driving an air cooled Porsche




This kit would be better if it came with a different hose option so you can eliminate the extra fitting and line from the master to the prop valve.

Well im starting a new engine build. clearances will be tight so i needed too see what the valve overlap looked like.


i shortened up a timing belt and adapted a tensioner to the head so i could better watch how the valve move inside the head.

Very cool stuff, hope you update with more testing and results.

What in the hell was going on with the dyno on the MCE rig?

Horsepower swinging back and forth by like 20WHP and AFR swinging back and forth from 12 to 14 above 5500 RPM?

Everything looks nice and smooth on the dynapack.

Good question! Shitty o2 feedback. Turned it off and it smoothed out. Haven't run o2 feedback since

im probably stupid for this...

All the seats and guides are out of this head.




more on this project maybe by the end of the month Big things happening, possibly never done before to a miata head.

Never before done, and the seats are out. Looks like my friends head when he was convinced he could fit small block chevy valves in a tiburon head.

I've probably drank beer out of the aluminum made from that thing by now.

Finally got around to cutting up some aluminum. ported roughly around the valve guide first, then put in the new guides and oversized seats.then a little more roughing. I know i am losing out on velocity with the big valves but then again this motor wont live below 4k or even 5k for that matter.

stuck the approximate sized valves ill be using in the head. these will probably get trimmed down .5mm each or so.



put the exhaust seats in today also. you can see how much bigger the throats will be.


And finally ran a radiused cutter through the throats

What valves did you end up choosing?

Twibs415

iTrader: (8)

They will be custom ferrea or made from ferrea blanks

Iv been side tracked and have been working on an itbr setup for my car. not finished yet maybe next weekend ill have it setup and start messing with the tune.

Im curious how the hp curve ends up

looks like it will be fun to tune...

got my itbs all setup and running. headed to the dyno Tuesday for the disappointment.



Also got my car on the scales after removing some "stuff" looks like front to rear ratio is better. This is with a half tank of gas without me. Time to find the last 44 lbs to remove.

Thanks for the pic of the Wilwood master. My kit from V8R came without any instructions, and even though it seemed pretty self-explanatory, I was scouring the internet for pictures of the lines so I didn't **** something up. The line exiting from the top of the tee is the one running down to the front left caliper, correct?
