NA - Cold Air Intake, Headers and Hi-Flow Exhaust

Postby Investo » Sun Aug 29, 2010 11:30 am

Hi everyone,

I have a stock NA 89 Import and am thinking seriously about having someone, probably MX5 Mania, install a cold air induction intake, headers and a hi flow exhaust.

I am wondering if people could share their thoughts and experiences regarding such an installation .... Interested in hearing what people think the advantages and disadvantages are...

Can anyone comment specifically on the MX 5 Mania product and service and what I can expect performance wise, should I go down this path...

Looking forward to the thoughts..

Cheers

Investo

I got them to fit the CAI and my full exhaust on my NA8.

top work done, and in good time too :)
Looking for an SVT motor for this:

Thanks for the post. Did the CAI and exhaust offer you more in performance? If so how much performance? Was there a noticeable increase in noise?

Worthwhile increase in engine performance, but also if you use the CAI that breathes throught the cowl area below the winscreen (next to the fresh air intake for cabin), then yes there is a noticeable increase in noise.

CAI or at least opening up breathing along with high flow catalytic convertor & cat-back exhaust is a very well trodden path on these & many vehicles. Next is usually better headers, although hard to improve on NB8, but NA6 from memory can be improved upon, & there's a little room for improvement on the NA8. Next it's usually a piggyback or standalone ECU, depending on which State etc you're in.

In terms of how much of an increase in performance you can expect on an NA6 with CAI & full exhaust from engine to rear bar, from memory no more than 10kw, & that's assuming a full & recent service to ensure already optimal engine performance. I'm sure that NA6 owners that have done this can better advise. Btw, increasing the timing on the NA6 from 10 to 14 degrees is also popular.
