what hp would a build 1.6 and 1.8 engine take
I am just wondering what the maximum built hp a 1.6 and 1.8 engine would take, obviously with supporting mods?
I am talking about forged pistons etc? thanks |
you could probably take a 1.6L to 450-500rwph or so, a 1.8L to 550-600rwhp or so, and a 2.0L beyond that.

Head work is the key to big power. A stock head will really stop you from getting past 500hp easily!

Hi Froogle,
It really depends on how much time & money you have to spend on the project. But I guess 500Bhp+ could be achieveable (you seen the youtube vid of the Greek guy with a high powered MX5?) Although at that power level you'll have to swap out most of the driveline etc.. as well... |
thanks for the replies. So why do people do a 1.8 conversion then? Why not just build their 1.6 with forged internals? Wouldn't it be easier?
|
The answer is Infinity!

no replacement for displacement. and we have plenty of folk with built motors. but we are also reasonable with our boosted needs. unlike the honda folk. 300rwhp on 195s sure isn't fun.

which 1.8 engine would be the best? I can get a 1999 engine easily
I already have a 1.6 engine with greddy turbo, 550cc injectors, spec 2 1.8 clutch and emerald ecu would I still be able to use the engine with these mods? cheers |

you could swap the injectors over....
you want +300rwhp, build the motor, perform massive headwork and ditch the greddy crap |

so everything will swap over no problem?
how much power will the stock 99 engine take? cheers But really, people make over 300whp on stock block but the general "safe" consensus is 250. https://www.miataturbo.net/forum/showthread.php?t=20544 However, keep in mind that you can blow up your motor while making less power than stock. It is all about the tune. Knock and you are dead in the water. Keep knock suppressed and you will have a happy boosted life. |

bigger displacement, even with same peak hp, will feel so much better: torque is awesome:D |

(My Opinion) Clutch SHould be okay and ECU I don't know anything about! |
