I've decided to stay with the stock twin scroll turbocharger. It will make the power that I want and twin scrolls are known for their very little lag. It will also fit in the engine bay and allow me to use the stock Saab manifolds. I sent it to Scroll Products in North Jersey to get the 19t compressor wheel upgrade and the bearing upgrade as well. He then sent the compressor and turbine housings back to me so I could powdercoat the compressor side and ceramic coat the turbine housing. I then sent them back to him to finish assembling the turbo and balance it.
I forgot to take some pics of the housings before I shipped them, but I will take pics of it fully assembled. Here are two pics of the compressor side already honed out for the 19t wheel upgrade. I do like Scroll Products....I've done business with them before upgrading VW turbos for our customers.
Turbo mods are complete. Now the 19t wheel upgrade is complete. I did the powder coating and ceramic coating in my shop and the project is moving along.
Dave, I like your way of putting a car together. There is absolutly no BS. You change all wearable parts, go through the car carefully, and most importantly you get to work and get things done.
I've followed your swaps over the years and I have nothing but good remarks to say !
Cheers !
BTW, good choice on choosing an 88 chassis.

88 GT, Loaded, 5-speed. 88 GT, 5-speed. All original.
It is port injected. The DI engines are all later years...and I couldn't find an application with the F40...only AWD and RWD. I really wanted a DI engine for the benefits, but from my experience with BMW's, I'm not sure if it is really worth the cons.
Guru, what are the cons to DI engines? I have heard they tend to build up more deposits than port injected engines if top tier fuel is not used. The previous generation (2008-2012) Malibu's offered 3.6 port injected engines attached to 6 speed automatics. Would that combination be significantly easier to swap into a Fiero than the turbo Saab version? I still like the idea of a manual transaxle better, but the greater availability of the Malibu driveline should make sourcing replacement parts easier.

The cons I have seen with BMW's are excessive carbon buildup on the back of the valves. It can be so severe that the cylinder head has to come off, but normally blasting the valves with walnut shells can fix it. I've also replaced camshafts and high pressure pumps on the Audi's. There are a lot of pro's with the DI setup too. I chose the Saab setup because it met every aspect of my criteria. I wanted a factory turbo four cam V6 with a 6 speed. It will make the power I want to make. The Fiero is not a good drag car and I find shoot for a 10 second Fiero is not what I want. If I wanted to build a 9-10 second car, I'd buy a Supra and put the proper safety equipment in it. I want a fun to drive car that is quick, but not overkill. I'm building this car to please me. I had to buy some parts for it and the local Caddy dealer sold me everything needed. Most of the parts for this engine is on the Caddy version.

The Saab V6 turbo/6-speed manual will make a great powerplant for the Fiero. Plus, you can still say "It's a 2.8"
I anticipate it will also return pretty good mileage. The car should handle great and be a blast to drive. How does the stock engine and tranny compare in weight to the new combo?
I'm not sure of the weight....it is an all aluminum block, but it is pretty massive in size. I have no updates this week.....I'm just planning on putting some of the interior together on the car within the next week or two. I plan to dynamat the interior roof before I install the headliner.
Guru, who do you get your Powder and Ceramic from. I am getting ready to order some and realized the Price has gone up since I last ordered Ceramic.

I finally had a new windshield installed and had the window guys install the quarter windows. I asked for them to put a rubber seal behind the quarter windows and it looks so much better then when there is no seal. It adds to it so much.
My tint arrived a few days ago, so I plan to tint the windows 5% (limo black) while the interior is out. Normally the headliner has to come out to get good coverage on the back window. Once that is done, I'll work on the interior and install the suede headliner.

Where did you get your quarter windows? Could you post some pics of the windows installed with this rubber seal.
I took a few hours for myself today and went to the shop to play with the car. I tinted the rear window with 5% non reflective tint. Then I wound up recovering the rear carpet piece in suede and then I covered the fiberglass headliner in suede. Once the covering was done, I covered the back of the headliner with thin Dynamat. I thin it came out pretty decent. The next step is to start assembling the rest of the interior and order the Momo steering wheel.

Dave, in your opinion, if this engine was tucked up against the firewall, would it be possible to mount it longitudinally with a Porsche Boxster type gear box or is the engine too long?
I had to work on this again as I need to free up the lift, so I spent a few late nights earlier this week getting my car mobile.
I really hate that hump, and it didn't clear the oil pan, so we cut it out and welded in a flat piece.
The front engine mount bracket.....not certain if it is the final product yet, but it puts the drivetrain where I want it. It uses Rodney's front engine mount. The rear trans mount is much thicker and the final product is done. The front trans mount is a stock Saab with a poly mount pressed into where the rubber was.
New Momo steering wheel installed. Not much else to report. I plan to replace the brake master cylinder this week and flush the completely dry brake system with the ATE super blue.

Nice work, I love seeing your creative choices of swaps.
Looks like you have more room in there to work on that engine than in the 9-3 Aero. My family has one and it's a pain to get to anything in that engine compartment.
Yes! I could see all of us here doing exactly that. For the record, the sparks don't hurt after years of being hit by them, so I can see why the guy doesn't flinch.
Crap, probably should have waited until I had my car back.
