mega squirt info

oh ya another thing i want to buy an after market 1.8 miata header 421 is there enough space with the wheel wells in place?

aftermarket miata header. I personally haven't used one of these yet, but as long as it fits like a stock 1.8 manifold- it should work without any problems. The exhuast is closer to the engine than it is to the body- fenderwell clearance should not be an issue. You will have to trim a peice off the transmission though- no big deal- but it won't fit without cutting a tab off the side of the trans.

What sesnors do you need? Depends on what you are going to do- what kind of power you want to make?

I used GM Coolant temp sensor and intake air temp sensors- just for ease of setting everything up. I used a narrowband o2 sensor- the stock mazda one works pretty well actually. I will use a wideband when I go turbo though. I don't know what you are doing for an intake manifold or throttle body- the stock tps sesnor will work just fine on whatever thottle body you use- megasquirt can use just about anything. Other than that- tht's it man, not too many sensors for ms.

What are you going to do for ignition? EDIS?

Do i have to use edis? does the kia motor have a dist or does it have a cam mounted sensor? i haven't picked up my motor yet that pully you got could i get one of you or who made it i see trigger wheels but im not too sure how i would mount it

for intake i'd like to use a upper turbo manifold

if you are using edis- you will need some type of igntion controler, as a kia engine does not have a distributor, it uses coil on plug ignition control by the kia ecu. The kia iginition system uses a wasted spark type igntion with mutlispark- similar to ford edis. Ford edis is awesome because it is a complete standalone system- and can be configured to work with almost anything- which makes it perfect for use with megasquirt and the kia engine. For awhile- i used the stock kia coil packs- and used edis controler and it worked great. Now I'm using the ford coil pack- because i switched to a genuine Mazda dohc valve cover, which doesn't have any holes to mount the kia coil packs to.

To use EDIS- you will need to get the 36-1 toothed wheel adapted to your crank shaft pulley. Your local machine shop should be able to do this for you with a simple lathe operation. Then you will need to make a VR sensor mount to point at the wheel- pretty easily made out of some scrap steel. I can give to specifics on air gap and sensor alignment later- when/ if you do this.

Once you have the wheel mounted and the vr sensor mounted- you are good to go! Not that much to it.

The upper f2 FWD manifold works very well for using the kia lower manifold. The kia TB sucks too. I just finally completed my custom sheet metal intake- using a genuine mazda fe3 intake flange- (so proper injector bungs are in the flange- no gay air shrounded holes from kia), then it's all custom sheet aluminum runners tigged to a 4x4 plenum with a 60mm mustang TB on the front. The intake is bad ass- flows some serious air. Runner length is only 4-5 inches- ready for turbo!

Here is a nice essay on the kia swap. Enjoy!

The Kia Sportage engine from 95-2001 is a duplicate of the infamous Mazda FE3 DOHC 2.0 liter I4 engine. Kia bought the tooling rights from Mazda to produce this motor in their Sportage, lucky for us! The Mazda FE3 is an F block, just like the Mazda B2000/ B2200 FE 2.0 and F2 B2200. Also the same as the Ford probe/ mx-6/ 626. The FE3 uses a block that is almost identical to the 86-87 B2000 FE engine. The difference is the oil return passages are different, for the DOHC, oil squirters are ulitized, and the water pump housing is slightly different. This makes putting a Kia head on a B2000 engine impossible - unfortunately. Nevertheless, the Kia Sportage engine is the FE3, and can be swapped right into a B2000/B2200. For more information about the FE3 engine, see any Mazda website like solomiata.com, mx6.com, probetalk.com, 626.net. They all love the FE3, just as much as we Mazda truck guys will too.

The Mazda bellhousing bolts up to the Kia block, and the stock Mazda motor mounts will bolt up to the block as well. Assuming you have a manual, the Kia flywheel must be used because The Kia uses an 8 bolt pattern on the end of the crankshaft unlike the mazda 6 bolt. The flywheels, other than the bolt pattern, are the same, so your mazda starter, clutch and pressure plate can all be used, including the pilot bearing and throwout bearing. Make sure to use locktite on the flywheel bolts- not only so they won't back out, so they won't leak oil onto your clutch!

If your truck is bodydropped like mine is- you will have to watch the clearance between the head and the firewall pinch weld- it comes close. I just trimmed mine alittle. Also the heater hoses will hit the head. I am not running a heater right now- so I just bypassed it. Also with a bodydropped truck, the stock intake manifold will not clear the hood as it goes over the valve cover, not sure if it will even clear a non-bodydropped truck. I used Honda CBR600 f4i throttle bodies on mine- I cut the stock kia lower intake and reused it- connected the TB's with silicon tube and hose clamps.

The Ford probe n/a or turbo first gen/ 626/ mx-6 upper intake will bolt onto the kia sportage stock lower intake with a little wallering out of the bolt hole flange. It has a nice TB with a tps sensor, IAC valve and intake air temp sensor. Mine works great except it sticks out of the hood.

The Exhaust- you definately will not want to use the stock kia exhaust manifold as it sucks- so go get a 1.8 leter mazda miata exhausat manifold and A-pipe. All you will have to do is redrill some of the bolt holes on the manifold flange and the ports will line up exactly! Bamm- Instant header!

Use the stock mazda oil pan- as the kia oil pan will hit your crossmember! Use the stock Kia windage tray, stock mazda oil pump pickup tube, and change the dipstick tube to the mazda.

Coolant hoses. I used the stock mazda lower water pump inlet on the driver side of the engine. It has a nice curve to it that points right to the lower radiater outlet. This allows you to use the stock mazda lower radiator hose- which is nice. Use the Kia metal tubes that go around the block. The mazda ones will not fit around the dohc head. I cut and fit an upper hose for the radiator, and used the stock radiator. I am running electric fans, so I didn't use the kia belt fan. The kia fan is driven by a four groove belt. It will be difficult for you to get the alternator and fan to work unless you have all the brackets from the kia for the engine accessories and the kia alternator as well.

I used the stock mazda alternator and bracket. I also used the Kia crankshaft pulley. The mazda pulley will not fit unless you redrill some holes. I didn't feel safe doing this because I needed to have absolutely no wobbling in my crank pulley as I used EDIS ignition with a crank mounted VR sensor. To use the stock mazda alternator with bracket and the kia crankpulley, you will have to take the mazda fan pulley brack- cut off the fan part so it will clear the kia timing covers. This will hold the upper bracket for the alternator. The mazda alt uses a v-groove pulley, so go get a 95 hyndai scoupe alt pulley and swap it out with your mazda alt pulley and you will have a four groove alt pulley which will match the 4 groove pulley on the kia crank pulley.

The only other engine acc I have is a belt driven air compressor for my bags, which I made a custom bracket for. Any other mazda engine accessories like ac and power steering will bolt right up to the kia block, and the kia pulley has v- grooves on the ac and psteering pulley grooves- so you are good to go!

Other items of interest. I removed the kia oil cooler and pulled the threaded oil filter shaft out of the old mazda block and used a normal oil filter setup. You can use the kia oil cooler, you will just have to fab some coolant lines to it. I used the stock mazda wiring in regards to the oil pressure sending unit, the coolant temp sender- on the kia it's in the front of the engine on the thermostat housing- just extend the mazda wire and put a female terminal on it. There is also a coolant temp sensor in the kia thermostat housing for your fuel injection setup. This will have to be calibrated to work with ms-2. I ended up using an adapter and istaller a GM coolant temp sensor for ease of programming

I used EDIS 4 igition from a 93 ford escort. I had a local machine shop make a pulley which presses into the kia crankshaft pulley to mount the 36-1 tooth wheel onto. I made a custom VR sensor mount from scrap metal. I used the stock Kia coil packs with the edis system. Kia also used a wasted spark ignition system like ford edis, with multispark as well. So the Kia coil packs are ready to go!

I used MS2 with ignition control for EDIS. So far it's working out well!

Let me know if you have any other questions, I hope this helps you out!

Do i have to run a mass air flow sensor?

ok another question about the fe3 which year turbo probe manifold? i can get either gen for cheap

I'm not using a mass air flow sensor, I'm using speed density algorithm for fueling. Alpha-N(mass air flow) can be utilized with ms though-

Turbo manifold from probe- are you talking intake or exhaust manifold?

Exhaust manifold is not a fit to the fe3- not even close. Intake manifold- the upper plenum will fit onto a lower kia manifold, with some slight modifications. Any89-92 626/mx6/probe turbo or non turbo upper intake will work

like you said further up though, the bp stuff works ok with a redrill, so you can get a gtx bp turbo manifold and use that provided it doesnt fowl the engine mounts etc. i'm not sure how it lines up.

maf and alpha-N are different. with maf you literally measure the air as it goes in, ms can handle that too in some forms. alpha-n is only for itb cars really. speed density is for all others.

Jim, not sure if you know, but the latest ms2e code can run hybrid alpha-n and speed density mode. you just tune twice once for each, and then blend together :-) if you havent upgraded already to that code, you should, its awesome! grab the latest beta, or the v2 release in a few days/weeks when it comes out.
