Hey Guys,
I've rebuilt a 1993 Astina BA 1800cc. (rebuilt at 375,000KM due to low compression)
I've swapped pistons from a 10.5:1 MX5 and done a full 2.5" exhaust as well. Installed a HKS F-Con pro 3.24 and it made 130 WHP at Dynojet. (also upgraded fuel pump and injectors)
Then I've installed a 4AGE black-top ITB and did a re-tune and it made 138WHP. I know it's not a lot of power but hell a lot of fun to drive.
I'm thinking of keeping it NA as long as possible. So I believe my next upgrade should be cams... I've looked around and so far only found $800++ camshaft sets (without springs etc) from MX-5 NA8C.
What do you guys recommend ? I'm not necessary looking for a crazy amount of power but something a bit more would be nice.
Thanks in advance.
Here's my dyno results after ITB
