This is what I have done to this particular engine, I already have an upgade engine planned though ; )
I had this motor listed as a 3.4, but the bore didn't match the GM factory specs, even though it has an "A" on the block so I concluded it was a 3400 at the least.
Due to heated debate at other sites I have now came to the conclusion it had an .030 over bore when I got it.
It was bored again .030 over which increases its bore and size to a "small" 3.5 liter.
If you know about engine sizing you may understand what I mean by "small"
A 1.6 can go from 1597cc to almost 1.7 liters and still be considered a 1.6.
This 3.5 liter engine has roller rockers(1.6 ex 1.5 intake) hardened pushrods and a roller chain as well as roller lifters.
It has a remote oil cooler as well as a high volume pump with high pressure spring.
It runs a set of ported 3.1L cast iron heads (bump left in,it helps bend the air into the cylinder so dont ever grind it off, it is worth 17% increase in air flow.) with high lift springs and hardened retainers.
The turbos are I.H.I and are quick spoolers,they will be set to 12 P.S.I. at the intake.
The engine will have a compression ratio of about 10 to 1 which is why im not going high boost.the higher compression eliminates low end power issues.
I turned the lower intake around so the water(coolant) was forced through the whole engine to exit the intake and not short cut out the front like a stock engine.
It has a 180 stat.
I used a 93 firebird 3.4 front cover to accomodate the aluminum pan that acts as a stud girdle.
I also made the headers(s-10 4x4 headers,cut and recontured with new collectors) and pressure plenum for the turbos as well as the intercooler houseing.
I used the intake from a 3.4 rear drive firebird and heli-arced a flange from a 3100 engine to it so the throttle body would work with it.
I am now using a obd2 coil pack computer and wiring harness ( modified ) from a 98 grand am.
With a lap top and a new program this setup will give me more control than the obd1 set up could.
I have 2 crank sensors now and 1 cam sensor as well as 6 different coils ( coilpacks ) one per cylinder.
And 1 injector for each cylinder/ coil pack.
What this will let me accomplish is tuning each cylinder as if it were its own seperate engine, so each cylider runs as good as possible.
Then linking them all toghether.
When I do the ecu upgrade I am trying to get egt gauges, one for every cylinder, so I can watch my tuning both by 02 and heat out put per cylinder.
I want to make as much hp as possible ( obviously )
The nitrous system will have 3 nos and 1 fuel output.
2 of the nos nozzels will be mounted in the intercoolers ( one in each one ) on the input side before the intercooler core to cool the cores as it goes through.
The 3rd nos and the fuel will be in a fogger in the intake and the fuel will be matched to all 3 nos jets.
It has a 4 speed stick with a viscous posi and a 343 rear diff.
The clutch is made with solid steel backings and tight springs as well as a kevlar, yes kevlar facing.
It is 200% more clamping force than stock.
When I used to shift into 4th a about 120 mph with an older engine in a different fiero It would still jerk you back, you could actually feel it bite at that speed.

As a final note, the exhaust/ turbo system ect... and the engine are put together as one piece, nothing ataches to the body frame as it is all one unit, this will make it very easy to drop the whole engine and tranz assembly as one piece if I ever need to take it out for servicing, just unplug the harness and remove 2 radiator hoses and 1 clutch line the throtle cable and shift cables, then the whole thing on the sub frame will come out in one piece, pretty sweet I think.
Now to test fit it...
