are you running a kl or fs?

if it's an fs heres some protege internals
StreetUnit.com - Premier MAZDASPEED Performance Specialists
this would give me some reference for prices.....

Boost scares me since I'm don't know a lot about car reading these forums for the last year is helping and rebuilding a motor will help. Frankly though lack of ecu support and tuning costs is what's keeping me from Boost. I am probably wrong but it sense like a huge cost. Like 3k or more to get it properly executed then my motor isn't even where it should be. Hla tick, bad valve seal....

I am starting to get a laundry list of stuff done to my car. Does that make it fast? No! Does that mean i spent too much money on a toy? Maybe. Do i have fun every time i jump in my car and drive? Hell yes.

You CAN do a boost setup for under $3k. Just depends on if you want name brand stuff or knockoff stuff. Megasquirt is the best way to go and tuning can be fairly cheap or expensive depending on how perfect of a tune you want/need. If your going to do anything on a car you should do it the correct (usually expensive) way. For instance, I just purchased a built motor that was built almost 10yrs ago and I COULD just install it, but I'm going to pay to have it tore down and make sure everything is still lubed up and no corrosion from sitting. A lot of money but could blow up a lot more if something is messed up. And the best advice of all.....research like crazy before you open your wallet

Does ms have a plug for the 4cyl ecu? I was under the ASSumption that the kl was the only thing they had support for cause of different CPU pins configuration and Ford/mazda hadn't released that for production to other companies.... Are they the "same" looked on their site and that was apparently true unless I overlooked something.

Megasquirt can be used on the 4cyl . There are members on here and Probetalk that make PnP (plug n' play) units so you don't have to hack into your wiring harness.

I've been learning megasquirt on a diypnp

DIYPNP Nippon Denso 76pin Unassembled Kit DIYAutoTune.com

no need to hack up your harness. It's pretty simple and there are guides everywhere to show you how to build it, get everything working. It'll be good if you know how to read wiring diagrams before soldering this stuff. Or you can pay someone to build you on. On the miata forums I go to, there are 2 or 3 people who build the megasquirts for a minimum fee (miata.net or miataturbo, Braineack or Reverent). I'm not sure if they'll do one for an mx6 or not, but I don't see why not

Also, you'll be using Tunerstudio on your laptop and it's kind of a high learning curve, but once you get your car running, things are pretty easy, especially if you've registered the program ($50), you get to use the autotune function which tunes the car (fuel tables) for you while you drive around like normal

If you want more features than the diypnp offers, there's always the MS3/3x which is the latest and offers control of up to 8 cylinders. diypnp and ms3 offers controls for electronic boost control, cooling fans, launch control, sequential injection, VRIS triggers, etc.

im trying to find out some brand names for r valves and what would be the best way to go for performance. im building my motor and need to find out some stuff for the top end. i already have the idea to port and polish the heads go with ze cams ze im,ze ecu,ze maf, and the bottom im not sure yet maybe wisco or je pistons with a 20'' mm bore on the block and the rods i dont know.. so some ideas is good on what rods i can use on the bottom end and valves for the top end..
this will be the first build for me..

Well... Are you going to keep this motor N/A? Or turbo it at some point? If keeping it N/A you will want a higher comp ratio. I mean it's doable with a turbo and high comp but lower comp is much easier to work with. So that's one thing to think about. If you're going all name brand high end parts look into what ferrea has for our heads valves/springs/locks/retainers.
Also if you plan to turbo, and bore that block out, you risk the chance of blowing out the side walls of your cylinders. If I read articles correctly our walls aren't that thick to begin with.
Reading Mac1's build's over on PT seems like a lot of the stuff he does is legit for a DD considering he boosts the [fizzle] out of his motors and they last for what he does.

Depends on how much you want to spend. If your going to upgrade everything on the engine your going to spend over $3k easy. If you can get a hook up on machining and assembly costs then that will help a lot. You would be better off getting a ZE for ~$900 and have 40 more hp from the get go and with bolt ons you could get around 200hp at the wheels (stock is around 140whp I think). And if you wanted to you could put a 50 shot on there.

i would blow my motor with a 50 shot i am a rookey lol.. but yes i did look ferrea i just found them out last night.. not bad i like them seems like the would be a good way to go for valves. they have a set thats bore and oem should i bore or stay oem on the valves. i am port and polishing the heads so i dont know.. ze ya i want to build the motor dont really want anything used.its just that u never know what that motor is been through for sure... oh and i did find wisco for 1600 bucks set at 11.5.1 that ipp selling them rods and rings to.. so ya if i went the 10.2 then i could still boost if i wanted to but i want to keep this N/A if i can lol

Doubt you would blowup on a 50shot, as long as you understand what you're doing you should be fine.
ZE+bolt ons and MS would be my choice if i were to rebuild my car. As it is, i'm just going to wait till this motor blows and get a ze. She isn't too happy seeing 6200rpm anymore

Yeah, 50 shot is as small as you can get I think. Ferrea is the most expensive valve train available for our cars. Your already looking at $3000 in parts just for Ferrea and Weisco combo. If your going to keep it N/A then your wasting your money building an engine. Your not going to push the limits of a DE or ZE going N/A. And if your going to build the engine and then turbo it your going to be spending an ass load lol

I wouldn't bother rebuilding that motor, get a ZE and call it a day. Get the correct bolt on's and a tune and you're over or at 200hp to the wheels. If you want more power put a 50shot on there and roll with that.

ZE is 10:1. The Weisco 10.2:1 will be a minimal gain...you could buy 2 ZE's for the price of the piston/rod combo you said u saw. If you wanted to boost later you could still do it. Plus that will be the quickest way to get your car back on the road.
