Here's the vid of how we got the car on its side. This was taken on our first attempt to flip it. So we were a little cautious, and it shows. Later, we were flipping it up and down in a few seconds, using two or three people.
Yeah, our turbo will definitely obstruct our drivers' view. We'll take rad-ness over visibility any day.
Our engine is still in bits and still no engine management. The list of tasks is endless. But we're chipping away at it...

Well, turns out the free crank we got (surprise!) isn't that great. All the bearing surfaces are scored. Running out of time, so we may just run it unless a known good 1.6 crank falls in our lap.
Did a little porting of the turbine housing. That little crappy turbo is going to need all the help it can get.
Will post pics of the weekend's progress later this week.

No pics of the results, but here's the turbo massaging in process.
and some of the rusty scale that makes our turbo free:
And the new heater we installed today:
Also, the valve lapping that happened yesterday. Lapping compound, a battery powered drill, and a vacuum hose to spin the valve stem is all you need...
Finally, our latest donor motor...
All we wanted from this poor thing was a crank. Three motors so far, and no good cranks. One has a bunged up keyway. One has a spun rod bearing, and this last one has a severe bearing damage and really grooved main and rod journals...

If I was building a lemons car I'd be focused on reliability and grip, I wouldn't want a speed penalty before the race started. I love the reroute of the radiator, dump some cash into the best tires you can get as allowed by the rules.
Since you plan to go turbo, you'd be better off with a full MS because of the MAP sensor. Couplers blow off, intake pipes get pranged, a stock AFM car isn't going to know what to do with that, and your race may be done, with the MAP you can have the entirety of the intake pipeing wiped off in a crash and still be back to at least stock power.

Yeah, the turbo will probably create more problems than it solves for us. Our new car is just something different for us. Besides, we've done the nimble-with-no-power thing already with our CRX.
But really, we doing this because the turbo was free and we've spent next to nothing on the rest of the car/parts. We can't resist the spectactular-ness of racing a car with a turbo a foot higher than the engine and its hood as a roof. It's like Olympics for mental defectives.
With that said, we're still empty handed when it comes to engine management.... might just have to run good gas and an fpr....

Our hollow justification for building a faster car, if I recall correctly, was that having more power would let us maintain similar pace with a less aggressive driving style, which should reduce the amount of body contact.
Had we maintained pace in the last race and not poked holes in our radiator and bent our frame rails until they rubbed on the alternator pulley, we would have won the race...
Now, we all know that guys will say anything to justify a turbo... I'm sure in reality each of us will have, at best, one level-headed lap before initiating a 2.5-hour powerslide...

I've got a potentially ghetto-fabulous idea rattling around in the back of my head- it's fuzzy still, but it involves a second stock '90-'93 ECU, paralleled to the first, only with the AFM signal padded down through a voltage divider. It is driving two injectors, which are installed just upstream of the throttle body. The system is set to stay off until boost is achieved.

This is the best build ever! I guess you are going to be at the Thunderhill event? I am tempted to drive all the way up there just to see this deformed turbo throwing beast run.
Oh and like Joe said, what kind of $ do you have left? I'm thinking a FPR would do in your situation, but if you have the $, a MS would be awesome. At these low boost levels, you could probably get away with just running some 1.8 injectors if you went with the MS.

What kind of budget (if any) do you have remaining here?

We do have the ecu and MAF from our '94 parts car... its a 1.8 so I have no idea if this is workable along the lines that you're thinking. Let's talk.
