I found a clean 1991 miata with a Jackson Racing supercharger. Comes with the intake, Jackson Racing header, cat-back (I forget the brand), and a few other tiny goodies. He said he's running 9psi non-intercooled from the original 5psi (went with a smaller pulley). He was asking 5k but the top will need to be replaced soon, so he said 4200. The hood/trunk have walnut damage from a tree, but that's aside from the point. This has been supercharged since 94, always ran synthetic IIRC, and the motor hasn't been rebuilt. Also, it's not a SNC vin number, so that's a plus. I'm curious as to what kind of power this is putting down, and if it's reliable/worth the purchase.

 

probably like 130rwhp.

 

Would that increase if I go the intercooled route?

 

it takes an mp62 with 16psi and e85 to make 190rwhp on a 1.6L SCer setup...

buy it, sell the SC and then turbo it properly

 

Hmmm... turboing (as I have been told) is quite the hassle to tune though.. I would love to go the GT28 route though.

 

this!

No

Please explain why adding more air via a turbo is any different tuning than adding more air via a SC.

I'll wait.

 

no it takes a real ecu and not a piggy back.

anything sc is worthless on this site to all these turbo guy unless your me =D

 

So easy, a caveman can do it.

That's cause you blow Hustler.

 

I just remember it took soflarick a **** ton of effort to break 170rwhp with his jrsc on a 1.8L...IIRC he was on e-manage blue

 

Didn't he end up with an S4?

 

yeah hes running a 2871 setup now.

what did i say about piggy backs? granted it's more ecu then any other piggy back but still a piggy back.

sc is harder to turn at idle but after that same as a turbo

 

Do it right, go turbo from the start. Either pick up that car (assuming it has decent suspension, wheels/tires, etc) or find another. Plus, if you are looking to make higher power...that rear end might not be up to the challenge. This is coming form a guy that has a 1.8 and a M45...making a earth shattering 150 whp. There are better deals out there.
