View Full Version : Any car folks? I just took on a HUGE project...

Man, the stack of instructions is about an inch thick.

My fun car is a '97 Miata that I have modified a bit for track use, but that is still very streetable. Right now it has a lot of suspension work done, but not much engine work; just an Eaton M45 supercharger and some piggyback fuel and timing boxes for ignition.

So, my new stuff arrived today. An Eaton MP62 supercharger, 440cc injectors, a/a intercooler from Track Dog Racing, Greddy EManage Ultimate, a Mustang throttle body, and new engine mounts and a powerplant frame brace.

I should be around 250 at the wheels when it's all done, not bad for a car that weighs around 2300 lbs. But this is going to take a while!

Here's a pic taken at turn one of Pocono's north road course, at about 100 mph:

You need to convert that into a Mega Monster Miata. hehe... I remember reading an article in a car magazine many years ago about someone who squeezed a blown Mustang V8 into a Miata. They had to stiffen and reinforce the frame and body otherwise it would twist itself into a pretzel if you stomped on the gas. LOL

Sounds like you'll have fun. Weight reduction will help a lot and as long as you keep the engine from over-heatin, which Miatas are prone to since they have such a small engine bay. Keep us updated. I got plenty more to say but I got to study. Peace.

I actually have a friend just finishing up a Monster conversion! Here's where he's at right now...

Some people have problems at extreme horsepower levels (300+), some don't. Some folks have wired their cooling fans to work together and 100% duty cycle. I've had problems with the smaller blower I'm using now, it spins pretty hot. The bigger blower will produce more power at lower (blower) rpms = less intake heat, plus the intercooler will help (and it comes with lots of shrouding)! Not sure how much lighter I want to go; it's more about the interesting project rather than how fast it goes. The corners are always more interesting than the straightaways.

It's a real kick for me to get back into this stuff after all this time. When I was young, in my late teens and early 20s, I was into it; I had a couple 421ci Bonnevilles and a '65 GTO. Then I lost interest for about 30 years. Now it's fun again!

I'd trade my left nut for a '65 GTO.

I used to own one. I took money for mine though, since I already have a left nut. I only owned it for 2 months, but it was a sweet car.

LOL! I love old GTO's. The '67 GTO is my absolute favorite car from that era. It's just gorgeous.

I understand what you sayin how the drivin experience is more than just goin fast in a straight line. I totally agree. Although the feelin of G's when the throttle is mashed wide open makes me smile to all ends. With a car as light as the Miata it isn't overly necessary to solely focus on weight reduction...unless you want to work towards the curb weight of a Lotus Elise (approx. 1300 lbs.). At that point I think you might want to just make sure everythin is reinforced so that the car doesn't rip itself in half under power. Another thing is aerodynamics. I'm not suggestin bodykits or wings like ricers (ugh) however I'm sure it can affect performance in such a small and light car. With such lil weight being thrown around I'm sure it can be easy for the car to lift under certain maneuvers. Even if only slightly if it reduces the grip to the tarmac and the power gettin to the ground to goin to hurt. Although at this point there are numerous ways to go wit the project all to gain that lil bit of extra performance. Lighter wheels with performance tires for better grip and less mass to perpetuate into motion, cross drilled brake rotors and multiple piston calipers, I could keep goin obviously and I apologize for babblin. Sounds like you are off to a great start.

Miata's are great cars! Looks like you have a healthy track car there...i currently own an 87 MR2 (if you know anything about these cars, you know they're GREAT for autox). However, it's my daily driver and can't afford to use it on the track. I'm currently in the process of doing a semi-restoration in terms of suspension and body work. After that will be the engine bay...thinking of going for the supercharged swap, or a 20v engine.

Lighter wheels with performance tires for better grip and less mass to perpetuate into motion

SSR COMPS in 15x6.5 (9.7 lbs each) (http://www.tirerack.com/images/wheels/ssr/swap/ssr_competition_ci3_l.jpg) with Falken 615s (http://www.stopandgotires.com/models/Azenis-RT-615.jpg)

cross drilled brake rotors and multiple piston calipers

Goodwin big brake kit (http://www.good-win-racing.com/miata/images/items/bbkv4d.jpg)... also Koni coilovers, JR front and rear sways, Mazdaspeed front and rear lip spoilers (underneath), three point front and rear shock tower braces, powerplant frame brace (to be installed), Hard Dog frame mounted roll bar, and FM Butterfly Brace (http://www.flyinmiata.com/Store/images/13-69920.jpg)... chassis work was the first thing I did, before I added speed I added handling.


I could keep goin obviously and I apologize for babblin. Sounds like you are off to a great start.

LOL, if only I could drive it as it should be driven, my reflexes aren't what they used to be. I get 2-4 track days a season, and maybe 3 autocrosses if I'm lucky.

Those early MR2s are phenomenal... even the later ones are great, but the early ones are so pure! I guy I know (not well enough to say friend, though) drove one to a top 5 finish in National Solo2 three-four years ago. I love those cars!

Touche'! Sounds like you got all the ground work done. I'm very impressed. It is difficult for most people to do work on Miatas and to do them well. I think Miatas are like street legal go-carts wit so much potential to be quick, agile, and fast if done right. The new MX-5 (let alone the MAZDASPEED version) just makes me drool. One day I will be able to fill my garage wit such my modified creations but for now all I can do is dream and discuss your plans and do whatever I can to help ya out.

Sound like you've got a nice little project going on. I love tinkering with cars and bikes. Here's a pic of me autocrossing, lost to a RX7 Twin Turbo that day. :redface:

Wow, you don't see many '28s these days; what year? How long have you had it? How are maintenance costs? Those are great cars, well worth the effort to keep one going; there is truly no substitute.

That's a 1990 928 S4 that I've had since 98, before this one I had a 1984 928 S for about 5 years. I bought this one from a doctor in B'ham, AL with only 30,000 on it, now it has about 60,000. Not the quickest off the line but one hell of a top end. It doesn't feel "happy" until you kick it in the ass at about 80 and then it's like a rocket ship! I do most of the maintenance myself but did have to put about $2,500 into the AC system a couple years ago. It's getting really tough to find a nice one anymore. I looked at a couple 95's recently, the last year they were made, but they were kinda ratty.
