My name is Thomas Müller. I'm from Stuttgart/Germany. I previously owned a RX7 Turbo II wich seemed to be a bit too hot for me... in other words: It started burning when I drove it one night because a marten tried to eat my fuel line.

The car was my hobby so I needed a new one to work on at the weekends. I found an imported canadian Miata with hardtop for 800€ in Ebay and bought it unseen. The car was a real surprise. It was completely rust-free and just needed some minor fixes and new paint because the pre owner tried to paint the car black but was not really gifted when it came to painting.

I allready fixed the paint, installed a flyin miata link ecu which I got really cheap (150€) did all the necessary maintenance stuff stuff including a new timing belt, new fluids, new gaskets, new hydraulic valve lifters and so on. I also installed the bigger 4 piston front brakes from a RX7 for more safety (and because I killed the small original disk brakes while having some fun at a lokal race track). Ofcourse I spent some money for a better suspension, too.

Here are some pictures:

First what was left after my RX7 burned down:


The Miata when I got it:


How it looks like at the moment. Got some square headlights because I didn't like the round ones:


Some weeks ago i decided it was time for more power. I allready managed to get my RX7 to 350hp all on my own so I guess I will be able to build a nice turbo setup for my Miata with some help from the forum. I want to get round about 200 hp with the stock 1.6l engine and a T25 turbo and maybe build a second engine with some better internals later if I get bored.

AAAAND there is allready my first question: How much psi would I have to run with my 1.6l engine and said T25 Turbo out of a 200SX to get my 200hp. and what would be the maximum pressure with my stock engine?

 

There's no maximum pressure, every turbo is different. I've got pretty much the same T25 I believe, and it's at 11-12psi and 185. So figure about 14-16psi.

The maximum torque is about 200-225 before the rods start to bend. Same for the transmission, it'll start exploding. The transmission is known to be safe if you're a little easy on it, but if you're planning on going above 225ft/lbs I'd upgrade to Manley rods.

WAAAAAAY before all of this you'll destroy your 1.6 rear end and clutch, so upgrade those first. 1.8 diff in the back, and FM/949 clutch is a good start for that part.

 

Curly is has done exactly what you want to do, 1.6, T25, tracking it. I would start with reading his build thread.

 

Welcome! I studied in Esslingen last fall, and frequently visited Stuttgart.

 

Welcome to the site Th0m4s, thanks for joining up!

 

A new clutch and a better differential are allready on my list.

I just read Curly's thread. Thanks for the tip.

Would 14-16 psi be too much for the engine? I really don't want to bend the rods. If 12 psi would be safer then I'd rather have fun with 185 hp instead of buying a new engine because I want 15 hp more.

The next thing i have to figure out is which manifold would be the best. I want to weld one on my own just because I can and I think it would be more fun to do build as much as i can on my own. The only question is which style I should build. I think bottom mount would be the best because the downpipe wouldn't have to have such a sharp bend but there's that stupid power steering pump. Is it even possible with that pump in place to build such a manifold?

Oh and I'm wondering if I should change the front bumper for one with a bigger air intake or maybe even build a v-mount setup? Going v-mount was a common thing for RX7s and it was very effective but maybe it would just be a waste of time to do that with my Miata. I'm a bit worried about the cooling system because I need to build that stuff really good. I don't want to stop every 15 minutes on the Autobahn because my car can't get the heat away at like 130 mph.

 

bummer about the rx7. Welcome to the board!

 

You do not need a V-mount to keep it cool. You just need the correct radiator and a nice oil cooler with proper sealing between the bumper mouth and the radiator. 949 Racing makes a good crossflow unit.

Ich wohnte in Augsburg für zwei Jahre. Wilkommen!

Stuttgart was a blast! The basement nightclubs in the old downtown were pretty cool.

 

Hehe yes Stuttgart is not bad if you're searching for some fun. Just the police knows a bit too much for my taste about what's legal on my car and what isn't

 

You guys have it rough for car modifications, but not as bad as Switzerland.

 

Grüße!

Ich war ein Jahr in Deutschland gewesen werde ich anfang Oktober bei ZF arbeiten. Wie kann mann ein Auto nach Deutschland importieren?! Wie funktuniert es wegen TüV?

Ich möchte meine Smurfette mitzubringen aber ich bin komplett durcheinander.

Vielleicht sehen wir uns weil ich glaube dass, ich in der nähe von Stuttgard wäre.

 

^I actually understand that but could never have composed it.

 

I've fallen out of practice. It's been 3 years since I've been...but now I'm trying to see what all is required to bring the car over. From what I understand it's ridiculously expensive in terms of insurance and gas to have a car in the first place. TÜV is also a nightmare (federal inspectors for emissions and safety).
