Just curious.
Mazdatrix did mine and i have
2000 miles.

 

Lucky7Racing.net did mine. I've got about 400 mileson it now.

 

ATK Engines rebuilt and ported my motor. I just recently sold the car, and it had about 25,000 on the rebuild and was running strong as ever.

Precision Import Repair Did a great job on my rebuilt. 1900 miles and counting

 

Who is the best at rebuilding a 1993-1995 13B? At a decent price? Mine 13B has no compression and want someone professional to get it rebuild and ported. Websites? Contact?

 

Pettit Racing built mine..I'm at about 8k miles now.

 

aznwired,

Contact Kevin https://www.rx7club.com/member.php

I have heard a lot of good things about his work and his prices seem to be fair.

 

thanks

 

I did my rebuild. 13,000+ miles at 400+ rwhp and counting

 

Ludwig Motorsports

Around 2000 miles, and lots and lots of 8th mile passes on slicks.

/HBP REW 62-1

 

mazda reman, does that count?
40k miles
at least 20 auto crosses and about 20-30 8th mile passes

 

atkins did mine, very large street port, 3mm 2 piece apex seals, race bearings, oil pressure mod, coolant passage mod, viton o-rings, hardened staionary gears, fully balanced rotating assembly. i have about 1600 miles on her so far and it pulls like a beast, i love it!!!!!

 

Self Rebuild with R.A. basic kit. +30,000 miles. T-66, Cleaned up ports.

 

Ihor/ Rich(rotary experiment seven/ fd3sgoodfellas) did my rebuild the motor looks great had 0 miles on it right now because im waiting on a clutch. I will post again when the car is actually moving. But definitely two thumbs up to the two!

 

I did with about 5k on it

 

Rotary Performance/rx7.com - 3mm street port, 34,000+miles

 

Pettit blueprint streetport 12,000 miles

EVERYTHING is brand new in the engine bay, from the engine and turbos down to the vacum lines and aluminum AST

 

Ihor/ Rich(rotary experiment seven/ fd3sgoodfellas) rebuilt my motor great people and will do business again. kept more than excellent contact with me on the status on my motor. everytime a part came in they called me. pretty much every step they took they either called me or contacted me. good prices on parts and labor.

 

I built my own as I have always done for the past 25 years...My latest motor has 60,000 plus miles ~400 rwhp. My last engine in my personal car I sold is still going strong with 133,000. If you get a shop to build your engine ask questions.

1) How many engines have they built and how long have they been around?

2) Where did they learn to build and what types of engines and year cars have they done? There is a multitude of variables between engines and there are many, many "tricks" of the trade. They make a big difference in engine longevity and power.

3) There's no substitute for experience and also a good name.

 

^--133k on what motor/car?

Is that 60k at 400+rwhp on a 13B-REW in an FD?

 

pineapple racing did mine no problems so far

 

Fourport 13b with a 7 inch blower and I also ran nitrous on it for about 30,000 of those miles.

Yes.

 

I was wonderin' when you were gonna chime in!

 

This guy above me built mine. I have had motors built by 4 different people for my customers cars...when I used to work on FD's. I don't have the time anymore. But I have to say- the MOTOR BUILT BY CHRIS was the HIGHEST QUALITY I have ever seen. Any monkey can assemble a rotary, and most will last an amazing 13000 miles. When Chris receives my motors, he always calls and tell me exactly what needs to be replaced- right down to every single small spring, as well as bolts that have too much stretch to them. For the price I thought he was too good to be true, however, his rebuilds are the only ones I have never had problems with. Many rebuilders DO NOT replace the small parts that he does. They just slap together a rotary on top of a 5 gal. white pickle pail. Many builders do not have the contacts(mazda factory engineers), that he does, and many builders won't spend hours on the phone telling you about every little detail of you motor. I can't say enough about this guy. He talked me into getting NRS ceramic seals, and then built the motor that has stock seal compression numbers. If he didn't talk me into these seals I would have blown my motor 5 times already. I am not exagerrating, as I had APexi BNR fuel pump problems and was running lean at 18 pounds of boost, then shutting off, and then turning on again.....All I can say thank God for Chris. There are literally hundreds of motors built by him out there and he never receives credit for doing the highest quality work I have ever seen. Do a little digging and you'd be surprised at whose motors he has ported and rebuilt. Some of his customers are active suppliers on this forum. No one can compete with him as far as I am concerned.

Chris (mr rx 7 tt) built mine from a Mazda reman. Took a perfectly good new rebuild, tore it down, ported it, did his other cool improvements, rebuilt it...and it is going friggin' STRONGER every day, with about 4000 miles on it.

There are a just a handful of rotary experts, and I consider Chris at the top of the list.
