hahaha, I'm not real worried about losing. the 210bhp mxima weeighs almost 2 tons. Also my p5 with just a header and intake outruns the BWM 325ci's...that's a bigger engine than the 320 (which I believe is actual a 1.8L)

Moto, if we get a chance to race make sure to bring your check book!

HAHAHAHAHA! Wow thats funny.

let me know if you still need that ecu pinout mota...I have it

Hello people!!
Sorry for not checking back in such a long time!! I was totally overloaded with sick patients down at the hospital.
So now for the latest developments! I found out that my battery did not have enough amps to carry the charge of all the stuff on the car, and noticed that the lights would dim a bit at night with all the accessories on.. so I went and got a 75 amp Varta maintenance free battery and that made a big difference, even in starting the car up...
Next, the worst thing on this 1.6 is the wimpy and weak brakes! Even thought ABS is great in rain and snow, the brakes are just terrible!! Scares me to death sometimes trying to slow down from speed. So, I found a wrecked mazdaspeed in the junkyard and just bought its entire undercarriage (axles, wheels, links and disc rotors on all fours) and will be upgrading the braking system soon!! That I hope will cure the brake woes!!

As for my checkbook Roddimus, you can count on me but what about yourself?? haha
Thanks alot MacDaddy, I would really appreciate a copy of the ECU pinout, as I may want to install a Apexi SAFC to smooth out the fuel curve. Please email me at k_motamedi@hotmail.com
THanks everyone.

mota.. just found out from a company called Hi-Boost that has just introduced there turbo kit for our engine... 20 psi is our engines limits.... they are posting a video of it monday , ill get it for ya, so inother words.. crank up da boost...

Roddimus Prime

Shogun, that info is WAY inaccurate. There are a LOT of variables that you didn't take into consideration.

1. engine - Hiboost sells kits for the 2.0L fs-de engine. Mota-mazda is running a 1.6L engine. Totally different beasts

2. psi vs cfm - You can't just say it'll hold 20psi. You have no idea how much cfm of air 20psi on his supercharger will push compared to 20psi of boost from a turbo...think of it this way (turbo's only).. which would you rather have? 10psi on a T-25 (msp turbo) or 10psi from a T40e (my race car turbo). They will make vastly different power levels since they are sized so differently. You (nor juan) can speak knowledgably about what is safe for his engine since you know nothing about his blower he's using or his EMS.

3. engine/fuel management - engine strength is only about 25% of what keeps engines together under boost. Fuel/spark management is 75%. Without proper/decent EMS you will destroy your engine in a hurry....look at all of the MSP's with only 7-10psi who have slung rods .....me for instance.

I could go on and on but I think you get the point.

Mota, I'm sure you've got a lot more money than me if you're a doctor and not in some third world nation where their currency is beans. I'm still going to wager I'm a good bit faster!

nate0123

matty, hiboost did just release a 1.6L kit with a GT25R, and they do in fact suggest that the engine can hold 20 psi (probably with that turbo)

Quote: "Let me tell you that the internals inside this engine are much more stronger than the ones found in the 2.0, being a smaller engine. I can assure they can handle over 20 psi of boost safely."

Roddimus Prime

I think what I'm trying to get at is that you can' just assume 20psi is safe across the board....20psi from a T25 is a LOT different than 20psi from a supercharger...especially an axial blower like Mota-mazda is using. They are very efficient and sized differently than turbo's.

I know the 1.6L's are very boostable...they are almost identical clones to the boost-friendly miata's. I just wanted to caution against the statement "go ahead and crank the boost up"...

mota mazda

Thanks for the info guys... I already knew that the 1.6L Mazda engine is a TANK of an engine, and will take any abuse you can give it and keep on running. I am sure that it will easily tolerate 20psi of boost. However, I agree with Roddimus that it depends on what kind of boost you are giving it, especially what temperature that boost is at, and how much fuel is mixed in with it which is crucial to successful and safe implementation of that extra power. I have run up to 14 psi on this engine with no problems at all, except detonation and knocking that I couldn't cure, so I had to put on a boost restrictor to keep it to around 12 psi, which is the max boost I have now... the engine is quite happy with that and doesn't ping or knock at all. Pinging is the major enemy of boosted engines, either turbo or S/C, you can ask any mechanic that. If I can find out a way to prevent pinging I will then just remove the restrictor and go all out!!!
Still waiting for the ECU pinout MacDaddy!!
THanks

Here ya go mota

This should help although I cant make hide nore hair of this thing. Too many dam pins.

macdaddyslomo

thanks zero....

ShogunProtege

so mota ... when are you takin a vacation to a city with a dyno... i am curious to see the hp numbers on that thing....

and why exactly do you need the ecu pinout ??

mota mazda

Thanks ZERO!!
Nice job!! As I said, I wanted the pinout to see if all my readings are correct, and I am getting the best possible engine management out of the system I have installed. Also, I have a spare Apexi SAFC II laying around and would like to install this to perk up the engine response a bit (although it is already very good). Anyone who has used these units know that they are a very easy way to dramatically improve engine management and response...
Stay tuned for more updates!!
Later,
Mota mazda

Nice job, do you have more picture?

Hello dear, what turbo did you use?
