Contemplating Turbo - Stock NA OBDII ECU Compliant
 

First I'd like to say Hi!!! :wavey: I am new here.

Anyway, as the title says... I am contemplating installing a turbo system on my 97 M Edition with 60K miles.This system MUST be NA OBDII compliant. Local emission inspections require that they be able to plug into the OBDII connector and find no error codes in order to pass.

This needs to be a turn key, set it and forget type setup. I don't feel like constantly fiddling and tuning the system. Also, temperatures here can reach an excess of 100 degrees and as little as 30 or more degrees. Having said, that I rarely take the car out below 50 degrees.

This car is not a daily driver, but does get taken on road trips and the occasional autocross.

I do not need massive horsepower. My goal is approximately 150hp. I have done enough searching around to know that some one will say, once you have 150hp...you will want more. I am not interested in a 250 hp miata.

Heck, I would have considered the moss/jrsc m45 or mp62 if they were still available. It's hard to beat the ease of installations with those kits. But after some recent research, it seems as if the FM Voodoo or Begi S1 are the only/best option for my application.

Having said all of that (sorry for the long post).

What do you guys/gals think? Are there other options?

This is what I have come up with thus far....

New Systems - FM Voodoo $2,995, BEGI Shanghai-S $1,618.00

Used Systems - JRSC $???? (M45 or MP65)


Fuel management - Powercard $295, BEGI FMU $229, Voodoo Box $415

Timing Control - Bipes $225, MSD $135

WideBand - $164-198 (Possible Bung Hole Modification approx.$80)


I figure I need to have a wideband to best tune the system without the use of a dyno.

You'll probably notice I am going the band-aid route. I will look into a standalone in four years when I can get historic tags for the car and will no longer be required to be emissions tested.

we don't have a power mods or n/a section here, so I'm guessing you're cross posting from some other shitty forum.

Not a good way to start here

Well I do have a similar thread on another forum and was just trying to save some typing.

I apologize for that....sorry. :(

I'll probably get flamed for wanting to run band-aids anyway. I just thought this would be a good place to discuss the topic as well.

If 150whp is truly your goal, both the fm and begi will easily reach those goals.

Band aids suck, I'd suggest using a proper ecu and just swap back for smog.

Superchargers are.......well I'm not even going to open that barrel of worms. Lets just say this place is miataTURBO for a reason

Yeah...I didn't think the supercharger thing would go over well. But I have seen some people do have them here...or used to have them.

So I figured it was worth mentioning.

Besides, maybe someone coming here would have a supercharger they want to get rid of because they are going turbo. That will be the last time I bring up s*****chargers.

Onto the Turbos... After looking at the options I am thinking the BEGI Shanghai-S would provide the most bang for the buck.

BEGI Shanghai-S Turbo System Miata BEGi


Now lets say you want to make the system "more complete"

Shanghai-S Turbo System

- Material : Mild Steel
- Wideband O2 Bung : Wideband O2 Bung +$20.00
- Cruise Control : yes
- Turbo Size : T25 / T28
- Color : Black Powdercoating
- Intercooler Size : none
- Fueling Option : FMU/ FPR 90-97 Included
- Heat Shield : none
- Add Bypass Valve : none
- Add Oil Pan Drill and Tap : no
- Add Stainless Braid Coolant line : no
- Year of Car : 1996-1997
- Add Separated Gases Downpipe : No
- Ceramic Coating-Turbine Housing : None
- Ceramic Coating-Manifold : None
- Add Stainless Oil Drain Line : No
- Add Gauge Mount : Dual Gauge Mount +$39.99
- Add Boost Gauge : Yes +$55.95

This adds a bung hole for the wideband, dual gauge pod, and boost gauge for total of 1,733.94 dollars. Take that a step further and add a MSD timing control unit ($135) and wideband kit ($164). Grand Total $2032.94

So has anyone here installed the basic Shanghai with band aids and had success? I have searched around and could only find more advanced shanghai installations.

How about the FM Voodoo?

Operates at 6 psi
Garrett GT2560R water-cooled ball bearing turbo (standard)
0.60 A/R compressor, 0.64 A/R turbine
Garrett GT2554R water-cooled ball bearing turbo (no-cost option)
0.48 A/R compressor, 0.64 A/R turbine
ductile iron manifold
2.5" stainless steel downpipe
all pipes either formed silicone or polished stainless steel
Autometer boost gauge with white or black FM face and pillar mount
Cold air intake setup and free flow air filter
Turbosmart recirculating bypass valve
Voodoo Box fuel control

Total $2995

Add to that.. dual gauge pod upgrade ($10) MSD timing control unit ($135) and wideband kit ($164). Grand Total $3,304

To be fair...with the FM kit you get a Garrett and Stainless pipes as opposed to a Chinacharger and Mild Steel. I like the idea of a smaller turbo for added responsiveness.

Here is my (and I believe most of the forum's) opinion, if you're going to do a voodoo, just get the damn Megasquirt - it is not that hard to figure out and for the price of the voodoo and MSD or Bipes units there is NO reason not to have someone build you a basic MS2 and swap ECUs for emissions testing like Vlad said.

You can run with this idea or end up spending a bunch more money than you needed to replacing stuff in the future or be unhappy with your car in 6 months. Go Garrett, I like stainless but maybe not required, replace the plug wires now, pay for Tuner Studio now, upgrade cooling system before boost, replace clutch before boost, don't expect much without an intercooler, and if you get one make for damn sure that you seal everything around it after trimming or removing stock parts - air going around the radiator vs. through does not cool the water. Oh, and if you have AC, BEGI compressor to intercooler pipes can be a bitch.

Kraftwerks supercharger
94-97 Mazda Miata Base Supercharger System

I have it on my Honda Fit. Easy install, clean power delivery, and it's a piggy back ECU installation.

no piggyback, rising rate regulator only. there really arent piggybacks available for that car, just standalones or bandaids.

I'm not sure about the 97's, but AEM F/IC and Xede are two piggy back options. I've got a Link piggyback coming off the car, but that's a huge piece of crap. Both the other piggybacks "should" be good if you get the bug for more power. One guy here in Houston ran 550cc injectors on it.

Here's my plan for power and passing OBDII testing: I'll be running an enhanced MS2 and larger injectors. Hopefully to max out my 2560. When testing time comes around, I'll swap the stock ecu and injectors back in, and wire the wastegate open. Then drive around until the emission readiness codes are set.

^yep.
