Who said it couldn’t be done, and honestly easier than I thought it would be. Had to do very little modifications to make this work; it’s smooth and simple power (and very quiet power) without a fuss.

Yes, I kept power steering and A/C, and used almost all the MSM charge pipes. Fired it up today and it runs like a champ. Using a first generation power card (the ultimate in engine management with the Official Miata.net Seal of Boomer Approval) with a normally open pressure switch to short O2 signal to ground during boost. All in all, To have less than 500 dollars in this turbo install, which includes the 50 dollars I paid for the pressure switch and power card, I came out pretty good, and we can all agree it will still have better drivability than a MSM Miata with factory ECU; seriously, I am not joking when I say that either, it’s that bad...

As far as the exhaust goes? I am going with the OEM MSM downpipe with built in catalytic converter and I am going to weld that to the rest of the OEM NA exhaust (NA cat already removed), the goal here for me isn’t loads of power, I already have that with my 10AE turbo, the goal is 140 rwhp and equivalence in torque, and factory appearance, I don’t even want a boost gauge, just straight 7.5 psi wastegate should do it for me.

 

Here is a first start video, was impressed, no problems at all, no air leaks or coolant leaks, nothing. I maintained the IAC valve as well, a/c on and the car idled right where it should be.

 

Got everything bolted back up and the engine bay finished, the car drives perfect, quiet, simple, 6.0 psi of boost. Tallied up the cost, 564 dollars and sixteen cents, and a couple of weekends vested in this project.

Outstanding...

 

Good Job, looks stock.
now for the fun:
replace intake
replace tb inlet elbow and bypass valve
get a eBay downpipe while they last
replace turbo outlet to Intercooler pipe
replace Intercooler
Hope your “Ecu” can keep up

 

Nope, already got all that going on a 1999 10AE. I like this car because it looks stock and is more quiet than stock.

 

For what you're going for it's perfect. I approve sir.

 

Exactly, it isn’t the loudest or the fastest; but rather, refined, quiet, and smooth.

 

Did you install a wideband to verify power card supplies correct fueling in boost?

 

Used my innovate portable wide band, works good, on the rich side ((11:1)) but acceptable, no knock, 2 degrees of static timing retard. Perfect drivability, no perceivable difference in idle quality.



Got the oem fans installed. I’m done.

 

 

I had some questions on your build which is very nice by the way!

what did you do with the water pump coolant neck, from my research I have seen that the na8 coolant neck is to long and doesn’t not allow for the proper clearance.

for the lower radiator hose would I change it to allow for the intercooler piping?

does ever bring stay the same with the heater hoses?
