Hey guys,

I have been playing with forced induction on my Miata for a year now, using an M45 I got cheap from a co-worker when he decided to go turbo. Started out with the basic setup running 5.5 psi of boost and dynoed it at 164 wheel HP 139 lb/ft torque. I had some fun with it, eventually running a 14.855 @ 93.37 at US41 dragway. Then like any junkie I had to increase my dosage! I swapped over to E85 fuel with RX8 injectors and a walbro 255 lph pump, and swapped in a larger crank pulley and smaller nose pulley on the supercharger. Now making around 9.5 psi peak boost I put down 200 WHP and 174 lb/ft torque. This was on rudimentary fuel control from an old school non-adjustable power card. I then purchased an MS3 and started tuning it.

Before spring rolled around I had already decided to swap to a turbo system, and have chosen a BEGI S4 setup with GT2860 turbo, external wastegate, and the V-band housing. This used to be called the S6 setup before they changed their designations. Along with the S4 setup I am getting a full 3" exhaust system, ACT clutch, ACT pro lite flywheel, radiator upgrade, and coolant re-route.

Thanks for listening to me ramble

Very intelligent decision making sir! I read about you running a power card, I was like "oh god, here we go with another clown...what? MS3?? This guy just redeemed himself!!!"
Welcome!!!

MS3 from MS labs, along with a "logging inputs" box that has channels for 20 analog inputs that feeds its data to the canbus input on the MS3. I am a data logging junkie.

I have extensive experience tuning the AEM EMS stand alone ECU I used on my EVO VIII back when it was my toy. Ended up making 550 wheel HP on E85 with that setup. Any more and I would have needed upgraded internals. Man do I wish the miata could make over 500 on the stock block!

Later,

Keith

intro threads without pictures are stupid. 550 whp on a miata motor is also stupid (stupidly awesome but still stupid).

Here are the demanded pics These were taken just after I purchased the car. I will do underhood shots when I have the S4 system installed. I will probably do a "step by step" of the installation.

nice. that thing is pretty clean. When you do you should start a build thread in the media section. w/ lots of pictures of course.

Yup, incredibly low milage when I purchased it in summer of 2011, it only had 26,000 miles on it! It was somebody's weekend toy. I am right at 50,000 miles now.

Speaking of low milage, does anyone make standard bore drop in forged pistons? I would love to be able to pull the stockers out, do a hone, and drop in new pistons and rods. With the low milage I don't really need an overbore, but that is all I have found at miata vendors.

Looks like you are about an hour away from me. After I get my setup up and running we need to meet up! What setup are you running?

Before you start your build i highly recommend combing the builds section as well. There is a ridiculous amount of data on this site. It is one of the most informative car forums on the web.

I wish every noob read this before they did anything on our forum.

Plenty of pistons and rods out there. that link will kind of give you a good idea of what parts are good up to what power levels.

Keith, I have a SC 1990 car that I build in 2009 and am finishing up a 99 sport DYI EFR build right now, we can meet at Putman park next time you or I do a track day!
The 99 build is here https://www.miataturbo.net/build-threads-57/harolds-1999-sport-build-77297/

Hey there,

I have never been to putnam park myself, and when I look it up on the net all I see is stuff about "the club" where it costs $7,000 for lowest level membrership and $5,000 a year dues! I take it there are "non-club" days where novice's like myself can get track time?

Keith,
Look up 10 10th motorsports ( no affiliation) they do track days there all the time and you can request an instructor at no extra charge, there is usually a spec miata guy or two instructing great bang for the buck usually 3 hr of track per day
