speed density on mark
Alright, getting right in to this I want to convert my mark to mass air as I want to eventually be making this in to a very serious racer with some serious power. What I want to know is since the car may in the future be running either a twin turbo or supercharger setup and will probably see positive pressure should I convert now while ive got the time or not at all and if i do what is involved?

well for any power adder typicaly it is easier to tune an EFI car... however you could stay speed density, personally i'd go big shot of spray and keep it carb'd... jmo

My Mark isnt carbed it's the 87 HO and I have checked the vin it was one of the first 87 HO not the reused left over 86 motors but it is speed density and I was wondering what would be needed to convert to mass air.

RE: speed density on mark
Yea, the shop that I had my car tuned at suggested that I buy a stand alone system instead because of it being easier to tune. This is what they wrote me:
"As for the tuning portion of the car, we have come to the conclusion that most forced induction vehicles are not able to be properly tuned using the standard EEC-V system with chip tuning. We are having much better success with a stand alone system such as the AEM, Accel DFI, or FAST Systems. We are wiling to make an attempt at tuning the system you currently have, but it can become time consuming as well as expensive."
Maybe you could look into AFM's PMS. It has stand alone capability and isn't so expensive compared to those 3 listed above.

I think with as many people as their are here saying speed density is not such a bad system I will give it a chance and hey if i have problems with it later then that is when I will deal with it.
yeah abit more details would help, like your Megasquirt system
