We are setting up the worlds first Quad 4 "W41" supercharged fiero. (My own Ride)Still Looking For An 86 - 88 GT with No SunRoof!!... If you have one for sale PM me please... The motor is here and getting tore down for rebuild this week. Cometic 2mm Head gasket for boost. (No part number, custom Made) ARP studs part number (#281-4301), I have been told you can use BBC spring in the head for a much higher spring rate. I dont know if this is true. I know you can use BBC springs in the Toyota Supra 7MGTE heads and it works wonders. We are fabbing up the adapter plate to mount up the M90 to the quad and a idler pulley.... Already found the lighten flywheel, looking for a clutch.... People who have done this set up in the past on Grand Am and Cutlass 442 have run the 3.4 and 3.2 pulley and dyno'ed at or around 300HP on stock guts using only a AFC or FMU... I don't like that idea at all... However after one year the motors are still holding together on stock guts. I want to do a true tune. I am going to try to run the 7730 ecm with the help of Ryan (sinister performance). The quad 4 uses the 7749 so I would be kind of screwed because it cannot read KR/Boost. I know the $59 can read boost/KR so it maybe possible to run this setup on the 7730 and I will need a 3 bar map. We have about 10 of them around the shop... If not then megasquirt it is. We are still trying to fab up the intercooler or is it intracooler LOL... I'll post pics after NYE...
The transmission is getting sent out for a complete rebuild and LSD installed. The transmission shop is right across the street thank god...
I wanted to do the 3.8 S.C. but the idea of building a Fiero with a W41 Supercharged Quad and a custom tune is just an awesome thought. If you thought a Quad powerd Fiero was only fun after 3200 RPM all the way to 7450RPM, Just think what a M90 would do for that platform....

You got me thinking of the turbo install. I lost intrest in it and wanted to go with the SC plan again. Then Scott was doing some mock up work with the extra M90 and we found it would work and fit in the Fiero.... After Mike left today we started looking up parts like mad for this setup... BTW mantapart isn't cheap!!!

Have you guys theorized a price for this engine set up ? I think this is an awsome engine combination. The supercharger is a great idea to find lost low-end torque. Keep us posted, with a price of course

Thanks, Kevin
Yes we have it priced out already as an install. The hardest part was to R&D the M90 to intake adapter. Its been sent out to get duplicated. Thank god Scott can fab and Tig... The rest is pretty stright forward. The bigest problem is what ECM setup to use. It looks like megasquirt maybe the only choice but we have a few options still.
Would your fabrication be simpler if you could do something like say, put the Gen 5 teflon rotors into the much-easier-to-work-with Ford SC TBird M90 housing?
Also, while Code $59 is some good stuff, why are you so resistant to using '7749 ECM?
If you run the '7730 you may as well run the '7727 from W bodies since it has the same guts but its weatherized so it can live in the back and simplify your through-the-firewall wiring and whatnot.

7749 cannot read Boost from what i understand. 7727. need to read up on.

Edit - the next release of $59 is supposed to increase the range of the VE, spark and boost tables from 6400 rpm to 8400, so it could be an option for a higher rpm 4 banger.
Cheers

Look what I bought today... Gotta love craigslist..
Not an M90 but from a Saturn Ion Redline ...
M62
Were putting this on a 1986 Fiero with a W40 H.O. but we are doing W41 cam swap and ECM swap. We swapping the pulley as well and if the intercooler will fit that to but I doubt it will fit in there.
BTM call me.. Were ready.

it came in turbo Sunbirds and turbo Syclone / Typhoon trucks.
Yeah, that's where I get all of mine. Sunbirds and Firenza's. It was also used in the Bravada and Astros in some years and some C/K/G trucks (although most were the 7747 and 8747.

The M62 is pretty limited. Maxed out its barely good for 300hp unless you overdrive it off Eaton's map. When you do that, they don't last terribly long that way...had a buddy kill a couple M62s in a Redline with an overdrive pulley. 440CFM at STP is roughly 30lb/min, which is enough to make about 300 HP.

I think a ford Super coupe M90 is what you want. They are pretty easy to come by, and they are in a TINY form factor compared to any other blower. You might be able to gut swap it with some more modern rotors to up the efficiency. But you don't have to, to make good power.
Oh, and 7749's are easy to come by! 87-89 LT3 2.0L I4 Turbo Cavalier's and sunfires 87-88 LD2 2.3L Quad 4 Grand AM's (most abundant) 91-93 LB4 4.3L V6 Turbo Syclone and Typhoon

i think you might have had a typo in your initial post the 7749 does read boost and controls KR and with Promgrammer you can edit anything including the shift light ! Programmer also has 3 diff ways to control boost with the standard $58 code
$58 the stock GM code and most Syclone/Typhoon tuners are familiar with it. Promgrammer can be patched easily for wide band
using a turbo sunbird wiring diagram (its diff slighly from the 4.3) you will notice the injectors wired a little differently but rest is pretty basic... I found that the stock GT manual trans harness was fine to convert over.
$59 is the newest code and non GM it was developed by some syclone guys for the ultimate controller
there is a guy in calgary and several in the states that do email tuning etc with the use of Data Master you create data logs to send the tuner... he sends you a .bin to burn a chip or a chip depending on your level of chipping. (i burn my own)
the $59 forum has other project cars on the go besides 4.3 turbos.. and im sure someone will have a start up file for you to get going
let me know if you need any diagrams as i have quite the collection of 749 data. i only tune a few small things as im still a noob at this stuff
Programmer ($10) is the only editing softwear for the 749 that allows changes to the shift tables and some other stuff the other standard editors pretty much do anything else you may need.
another benefit from using the 749 is that you can use Moates adapters and have upto 16 diff tunes for the car that are switchable on the fly.. all on one chip
the Ultimate chip was developed using this hardware
have fun !

No, what Will Proper (Bill, William, TEXASGT, ReMixGT) "finished" was ripping me and others off and skating with thousands of dollars from his customers. IF he ever resurfaces, it would be best to avoid him, as he had done it before he got me in his last one and will likely return as most scumbags are prone to doing. BTW he was lying about this whole thing, the Quad4 thing was what he WANTED to do to a car but never even started, just like most of the bs that came out of him.
