I wanna get most hp gain without swap 1.6L SOHC

[serggio99]

Hey folks i just got an MX-3! red 93 SOHC 1.6 4cyl. I wanna know excactly all the things i need to modify ( i now to get new intake/exhaust, i needa know what more) to get the most hp outta the engine. I heard that it's 88hp stock. i'd like to maybe get a 20 to 50 percent increase in performance . please help me out! thx. (btw i have searched the forums. this question is not answered directly.) i welcome all suggestions. I DONT wanna swap the engine tho. thx for ur Help!

nitrous or custom turbo setup. there's not a whole lot to do with the sohc because of the head.

Ok...but what's really the max performance gain can i get from this engine? i

ashley, is there anyway to swap a head?

You'd really be wasting money to be building a SOHC like that. You could throw all the money in the world at it and you might get it to have 150 hp. That's because it only has one camshaft and stuff it won't get up in the hight numbers. But if you're demanding to keep the engine the two biggest power gainers would be new camshafts (I dunno if they make em for the SOHC) and a racing chip. The chip would help alot. It'd be good for say about 6-8 hp. If you've done anything before that i can be more. But if you wanna keep the engine.. go w/the serious bottle neck stuff.. (whatever is keeping the car slowest) And in the SOHC it's biggest bottle neck is that it only has 1 camshaft. So engine swappin would you so much money and time. But racing chip, ecu, intake, exhaust, and ported head will maybe get you around 120-125 hp. Compare the costs to just swapping an engine and decide yourself. Good luck.

Thx for the reply protegeSTS, i highly value your opinion. by the way, I'm in Gville too! Tell ya the truth, if i can get the car at 150 whp, i'd be happy. I don't wanna race. I just wanna peppy car. i guess i'd like to increase the torque some, and i've read in some posts that tightening the throttle line will give some more hp. After the CAI and exhaust, i'll have about 600 bucks left. I'd like to know if that's enuff to do it. Thx

"Please do not post useless incorrect info like this. Its not helping, but rather spreading misinformation."<P>What was incorrect about what i said? Sure if you wanted to you could get 300 outta it.. but the point is it still is a 1.6 SOHC. The 1 camshaft holds it back so much. I don't find that to be wrong.. or incorrect information.

from what i've heard on the forums, the chips offered for the mx3 are money pits. 6hp isn't worth ~$700.

They usually have less valvetrain mass as well, and as long as your rockers are in good condiition, there is no disadvantage. The one bad thing is trying to correctly tune a cam requires regrinds....but only the most "hardcore" people will take the time or care.<P>b) "throw all the money in the world....might have 150hp" Thats just silly. You could easily pull 200 whp in NA form, and MUCH MORE in boosted form. Remember, its still a B6 bottom end.<P>c) nobody makes a "Chip" for the engine, because Mazda uses non-rewriteable e-proms

i was referring to the chip corksport sells for the ecu just incase i created any confusion right there.

Hey I just read something about tightening your throttle cable to give you a better response. If someone can, could you let me know how do this. Plus I own a 1.6 SOHC, and it is slow but can get balls, so go for it. A turbo would be good, and then the usual stuff, like headers, 2 and a half inch exhaust, the intake, bore out the cylinder walls adding more space and power. Street wires and all the other goodies that add like 1 to 5 hp, it all adds up. OK, respond to me in my e-mail, MYMX3VEh@aol.com. Thank you. Bye bye.

[aznwithamx3]

is there any way to swap a dohc head from a sohc?

[mx3freakit]

What is the biggest HP boost for the 1.6 SOHC besides NOS?
