Kit was also upgraded with:
-
FM's all metal Blow off valve
-Tial 35mm external wastegate (with 9psi spring)

This turbo system runs GREAT and is in very good condition.  Several items have new powder coating and many new nuts/bolts are provided.  I'm only selling it because I have finally been bitten by the V8 bug and have started an engine conversion.  With this turbo kit, I have produced 240hp/228 ft-lbs at the wheels running about 15psi on a local dyno (see dyno page).  Very fun and VERY fast.  Driven daily and sleeps quietly on the road until you put your foot down... then HOLD ON!  It has very good streetable characteristics.  This kit was sold by Flyin Miata years ago called the "FM3" kit.  This is very similar to the "FM2" kit except that it utilizes an external wastegate (which allows for better top end performance under higher boost conditions).  Other than that, it is basically the same kit.  This was marketed by Flyin Miata, but several of the parts came from BEGI.  The smaller turbine and compressor A/R ratios allow for fast spool-up yet it maintains strong torque all the way to redline.  The turbo was rebuilt less than 5000 miles ago for minor bearing issue and still has very little freeplay (like new).  This kit in is truly in great condition.  I don't like buying junk on the internet from others, so I don't sell junk either unless I fully disclose what you're buying.  

Also included are replacement silicone air pipe hoses.  The orange ones in the pictures are also included as spares.  The blue hoses are more durable and I had intended to swap them out but never got around to it.  I went ahead and put the nicer blue ones on the pipes along with new hose clamps when I removed the system from my car.  A couple of the air pipes had some chipped powder coating and a little blue paint overspray from when my car was repainted, so I had the pipes and intercooler media blasted and recoated with fresh powder coating.  They look brand new.  There are two new turbo gaskets and several packets of new nuts/washers.  The turbo water jacket has two new silicone water lines.  The fresh parts and powder coating should make installation a little easier and look cleaner when done.

As for any negative things to mention, there are two things.  The downpipe and exhaust manifold had been originally ceramic coated mostly for cosmetic reasons.  Some of the coating has flaked off of the downpipe which now reveals some surface rust.  This is normal; the kit normally comes with a painted downpipe.  The paint normally burns off and the pipe takes on surface rust.  On this downpipe, most of the flaking is down low where the pipe is near the ground so it is not that visible from the engine bay.  The other negative thing to report is a small crack in the exhaust manifold.  This crack is at the flange where the wastegate joins the manifold.  The crack is minor and has been there for years without growing.  I do not anticipate this being a problem; it was probably caused by internal stresses that are now relieved with repeated thermal cycles.  There is no exhaust soot blowing from the crack.

The wastegate originally included with the FM3 kit was made by BEGI.  After repeated problems with the gate sticking, I replaced it with a Tial wastegate, which is what BEGI uses now.  It has performed flawlessly ever since.  The wastegate has a 9psi spring currently installed and I utilized a Greddy boost controller to reach boost levels above 9psi (I usually ran at 13-15psi max daily).  The spring inside the wastegate can be easily changed to provide different levels of baseline boost, however it is optimal if you use a boost controller for levels from 9-15psi.

The main K&N air filter was replaced not long ago and is in very good condition.  A valve cover breather K&N filter is also included.

Overall this kit is in great condition.  You won't be disappointed with the performance, condition and overall appearance of the kit.

(SOLD) Greddy Profec B boost controller - this is the original spec Profec B with three basic knobs to control boost. This is the complete system including the main controller unit, the solenoid, wiring harnesses, and installation manual (not shown in pics). I removed this controller from my miata because I'm doing an engine swap and will no longer use a turbo. It is super easy to use and change on the fly. There is nothing wrong with this system. Everything works perfect and it does an outstanding job controlling boost.   IMG_8919.JPG (957171 bytes)IMG_8921.JPG (763685 bytes)

(SOLD) Vishnu fuel rail (for 1.6L engines) includes hoses and fuel pressure regulator.  Great for high boost applications.  Helps minimize fuel pressure variance delivered to each injector.  Reduces chance of cylinder 4 lean condition (i.e. minimizes meltdown).   IMG_9254.JPG (1158499 bytes)
(SOLD) FM / ACT Extreme organic clutch (for 1.6L engines) - It has about 15k miles of mostly city use and is partially worn. Easily more than half life left. No problems with chatter or slip. Held 228 ft-lb of torque with no trouble on my turbo setup.   IMG_9257.JPG (1274486 bytes)IMG_9258.JPG (1219994 bytes)
(SOLD) 4.10:1 Torsen differential + housing + driveshaft + halfshafts (everything you need to convert a 90-93 miata to a Torsen diff setup) - This is from a 1994 Miata that originally had 48k miles.  Installed this on my miata and drove it an additional 47k miles so the parts have a total of about 95k miles.  It is a 4.10:1 gear ratio and is the Type 1 Torsen design (meaning the half shafts are in two pieces; i.e. they separate at a flange which leaves a "stub shaft" that goes into the diff).  I've run Redline 75W90 in the diff ever since I've had it.  I installed new seals in the diff (where the stub shafts go in) a few years back.  There are presently no leaks.   IMG_9293.JPG (1176279 bytes)IMG_9295.JPG (1006825 bytes)

(SOLD) 1.6L Engine This engine is in good shape, has been removed from my car and is ready to go. Unfortunately, I didn't do a compression or leak down test (stupidity on my part) before pulling it, but the engine was running great when I last ran it (11/28/2007). I have run a carefully tuned intercooled turbocharger on this engine, but have not abused it. The engine has 123k miles and has been lubricated with Mobil 1 oil ever since about the 40k mile mark. Oil and filter changes have been done religiously every 3-4k miles. The valve cover and intake manifold are both silver powder coated. The engine also includes the flywheel, crankshaft pulley, alternator, water pump/pulley/belt, NGK plugs and wires, ignition coils, CAS sensor, throttle body, and MazdaSpeed engine mounts. Oil pan also has provisions for oil drain from a turbo. With the exception of needing 2 small water temp sensors (which I retained for my V8 conversion), this engine is ready to run.   IMG_9260.JPG (1080959 bytes)IMG_9261.JPG (1053968 bytes)
