Na6 , built head how power on stock bottom end
 

hey guys, Ive been a member here a while and never yet posted.
I'm Dann, From Asutralia.

I am on my provisional licence (so no turbo's or v8's for me quite yet, and no 'performance engine mods') and have just ironed the bugs out of my new drivatrain, which includes a freshly rebuild bottom end, lightened and balanced with oem replacement parts, a good port and polish and a set of reasonable cams (Intake is 260 duration, 8.2mm lift - Exhaust is 265, 8.8mm lift), link Computer, brass buttom clutch and lightened 1.8 flywheel with a 6 speed and (unfortunately 1.6) 4.3 lsd. It also has some other bits and pieces adjustable cam gears different sensors Intake, extractors exhaust etc etc

My question is, I plan on keeping this engine and boosting it for a club racer (its regularly in club hillclimbs atm) and doing circuit days.

Am i stupid to keep this engine and boost it? As i have a reasonable base to start with is it really going to be worth going BP? What sort of power could i expect to make boosted? 220hp?

Thanks in advance,
Dann

Welcome to here. A fresh 1.6 will easily meet your power goals.

Hey mate thanks for the fast reply. Im looking for enough to keep with the quicker evo's at circuit days, I have plenty of suspension work , but i feel i need more bracing. I have never been in a 250hp mx5 the fastest is a friend of mines 130rwkw supercharged 1.8 NA.

Question is, how quick is 220 hp in an NA, are we talking about high 13's?

Thanks,
Dann

Probably mid to low 13's if driven properly.

Cheers mate, yeah so its not slow haha. ATM i'm working on getting out racing more in my ae86 rally car but im going to have to start looking for a manifold and turbo soon. again thanks a lot for the quick reply.

220hp in a stripped out race car will def be fast.. And fun ;)
