Naw it's just a volvo 4 cylinder. SOHC 8V. Basically my 
hope is to turbo it keeping as many parts as possible 
stock. There are 8.5:1 forged mahle slugs availible for 
the 2.3L- but they're fairly expensive, and it'd mean 
pulling the engine. And if I'm going to pull the engine 
I might as well rebuild it... blah blah. So as you can 
see that would get way out of hand and I wouldn't have 
the self control to stick to my budget. This engine is 
just and experiment to hopefully make the car driveable 
(117hp and 3100lbs is not driveable imo ;)) untill I 
can put a more serious engine in it. It has 10.1:1 CR 
as stock and 117hp. The hope is to get a 5 angle valve 
gring, port/polish, and the combustion chambers 
reworked for slightly lower compression. It's also 
getting a performance cam from a relatively high end 
tuner in Sweden (Unitek). With the head mods, cam and 
3" exhaust power output will hopefully be 150-160 (oh, 
it'll get a different ignition too but more about that 
in a bit). The turbo going on it is a mitsu TD05-13c. 
Fairly small, but it'll spool up like mad behine this 
high compression engine. And I only need 12 psi for 
290hp which ain't bad for a stock 2.3L with some bolt 
on's and headwork. This would make for a near stock 
green volvo station wagon that eats mustangs. Now 
that's entertainment. To help me get to that boost 
level both intercooling (either a cut down truck 
intercooler or 2 volvo cores) and water injection will 
be used.

Now, the ignition and fuel issues. It has a notoriously 
crappy chrysler ignition with NO boost retard feature. 
I see my choices here being either fitting an ignition 
from a factory turbo'd 240 which has boost retard, 
fitting and MSD of some sort, or whatever other options 
this list has. hint hint. Seems like the basic MSD 5AL 
BTM is tough to beat at 166 bucks. 

As far as fuel goes, it currently has LH 2.0 with 
bosch "yellow" 19lb injectors. Good for 150hp or so. I 
have 2 cold start injectors (worth 30hp each) wired up 
to be driven by the 02 sensor (they sense a lean 
condition). But that's pretty crude and only gets my to 
210hp tops. I see my options here as either being to 
fit an injection system from a late model turbo car (LH 
2.2 or 2.4), or do something like the mega squirt. 
Again I'm open to suggestions as according to Bruce I 
seem to be taken up with the overpriced commercial 
engine management crowd. So I'm looking to be 
enlightened. Thanks for any help! :)
