Lots of other details in the prep not listed. Just a few tuning tweaks away from 300whp. Tony builds race cars for a living so this car is not your typical tossed together backyard special. Over $25K in parts alone. New opportunity came along and they need the cash. $15K + depending on which extras you opt for.

If the OGK wasn't about 75% done, I'd buy it myself!

Whats he asking?

Sounds like a great deal!
He's asking ~$15k + depending on options, per Emilio's post.

!

Its basically what a lot of people were specing for the 'car of their dreams thread. Except that you get it for a bit more than a low mileage stock MSM.

GLWS, awesome car/deal.

it's amazing how cheap race cars are...

Yes it is forsale, I will not part it out. I don't have to sell it, something interesting came up and if I can sell it would allow me to jump on the deal. You can see it tearing up Buttonwillow the 5-6th and again the weekend of the 19-20th.

TC Designs sounds so familiar. Do you mess with a Genesis Coupe? I swear I've seen you post on gencoupe.com.

nope, not us.

Are you the "TC Designs Fab"? Maker of amazing roll cages, etc?

Tony did my cage, he is the shit and fucks tons of bitches.

He did my cage, and probably 90% + cages in miatas around our area. Stand up guy, if i ever had any business needs i would take it to him without a hitch.

SOLD

I struck a deal with Tony and now own the car. He did some great upgrades over the winter. I am in the process of finishing things up. The car now sports a 99 head, skunk2 intake, Autokonexion GT Widebody and 275 R6 Hoosiers.

Can't go wrong for the price at all. Lucky!

I am in the process of finishing the widebody install. I will post pics when completed.

Congrats on the purchase. Tony showed me the car when I stopped by TC designs a few months back. Awesome platform.

+1 for pics! Sounds nasty :D

Awesome, this better dominate and get you laid.

Here are some pictures of what it looks like today.

Dean Thomas wheeled the car around Thunderhill last month and turned a best lap of 1:54.6 over the crows nest on 245/580/15 R80 Hoosiers on 9"6UL's. On another lap he was 1 second ahead of the 1:54 lap till he ran into traffic. He had to short shift out of turn 15 due to sound (107db) and we were only able to get 2.5 degrees of camber on the front and 2.0 on the rear. With a better alignment, new muffler, 10" wheels and some more seat time he is thinking very low 1:50's.

What intake manifold is that in the third photo?

I saw this car today for the first time since it moved to its new home. It looks really well thought out. The engine bay was clean and way more organized than my old bp miata.

Honda Skunk2 intake with Miata flange. It's something that Tony at TC Design made.

Ron Davis Radiator. TC Design fabbed the mounting, air tubes and air box while Altered Acceleration finished the ducting and made the removable splitter.

That wing mount == Jesus Tits..

Tony did a great job on the wing. It is well supported inside the trunk. The idea is to get it far back for leverage and up high for clean air.

It looks bad ass.

Awesome car! Only thing left to do is change form Koni to XIDA's.

I want to make babies with that ducting. Beautiful work.

Looks awesome, I wantzzz.

That is high on the list of changes desired. It's still running stock brakes so that needs to be addressed first.

Is that splitter made of Alumalite? I can't tell because Michael J Fox is holding the camera and taking the pic days before he speaks, in which he intensifies his Parkinson's symptoms by not taking his prescribed medication.

I am not sure what it's called but it has aluminum skin with plastic honeycomb core.

It's that wonderful NorCal chronic causing the shakes.

Good, I have a sheet of that in my garage. Now, if only I could get a cheap spoiler.

I know of a couple pro level wings for cheap. Lmk when your ready, maybe we can get a better deal on 2. My wings going on the turbo crx.

In for swan neck.

I had to change the thread title, it was severely annoying me.

Wow, nice car.

I'm in loooove with this caaaaaaahhhh
Got a feeeeel for this automobeeeele...

Nevermind, hadn't seen the whole thread

How is pressure being relieved from the crankcase when the engine is in boost?

This might help.

Good question. I assume it's being pushed out the open vent on the drivers side of the valve cover.

WOW, That is my dream car. I love the autokonection fast back kit......I would have that in a heartbeat if they were available here !! (New Zealand)

Stunning. :drool:

That's the first think I noticed when I looked at the engine photo.

I spy red prancing horse:

prancing red horse, timing belt[s] exchange

There's something entirely fucked up and wildly appropriate about a Ferrari engine sitting on an old, greasy wooden rolling dolly.

ZOMG! that's win. Such a shame it's torqueless.

You're right, it should be in the fucking dumpster. :fawk:

Stepping up the game a bit with some AST5220's. After selling my Koni Race suspension the total out of pocket was 2k. Too good of a situation to let pass so I jumped on it.


The car worked so well with the Koni Race setup I was reluctant to make the change. I opted to keep the spring rates the same as before (850/500). This should make for a well controlled test since it's the only thing being changed.

I added the zero rate helpers after the purchase.

Why didn't you do tender springs instead of zero-rate helpers?

That is a can of worms I would rather not open. I looked at the pros and cons of each then ran it by Tony. We arrived at the same conclusion. Not sure if it was for the same reasons because I did not ask.

The scary part of the change is the possibility of going backwards. This thing worked so well with the previous suspension Dean felt I maybe making a mistake changing it. When I bought the car I asked Tony what would be the one thing he would like to change. He said the suspension with AST/Xida. Got to say you played a role in pushing me over the edge.

My goal is to make it a ST2 class winner. Track record at Thunderhill for ST2 is a 1:50.8 using the bypass. Assuming the bypass is worth 2 seconds we are within 1-2 seconds of it before this last round of changes. It's all about the free HooHoo's.;)

People do crazy things for that purple crack :)

BTW....this looks like 2 b-series forged at the hip......

New motor with forged internals, 11:1 CR, E85, Ported head, ATI Damper, oversize supertech valves, Supertech SUB, custom web cams and supertech heavy doubles.

Rebello ported the head and assembled the motor. Trackspeed supplied the supertech valve parts. I spec out the cams, Tony at TC Design fabricated the plumbing, Intercooler, radiator mounts, air filter housing, Skunk 2 intake and tuned the car.

Looks like somebody wants to race from a roll.

It's not a autocross car. It's a ST2 car that lives between 5,200 and 7,700 RPM's. With 4:10's and 6 speed it always in the meat of the power band.

Looks like fun :)

What's with the loopy plot in the lower rpm? I haven't seen that before. I'd almost guess wheelspin..

The loops are gear changes. The light 5.5" unsprung carbon Tilton clutch is a PITA on the dynapac dyno. You can't really slip it underload and high gear.
