haltechrx7

I've been driving RX-7's since 1981 and FINALLY NOW I will have boost!!
But I need to develop a "system" and I'd like opinions and suggestions from people who know much more about this than me.

I (with the help of very experienced friends) built a very nice Streetported GSL-SE 6-port engine. (Yeah - I know it's a strange engine to start with)
The only parts I re-used were the iron housings and the oil pan.
Everything else was Mazdacomp New.

The engine was "run in" on the bench. Started right up and has the best compression numbers one could hope for.
So the engine is ready for boost, and I used the "stock" rotors that have 9.4:1 compression.
I'm fuel injected using a Haltech E6X.
I have a MSD6A and coil for each plug running direct fire.
TWM TB's and pressure regulator (with an input for use with boost)
Racing Beat/Dellorto Intake Manifold Top, GSL-SE Intake Manifold Bottom.
Daily Driver and Autocross.

Turbo .vs. supercharger.......
I think the Turbo wins as the "better" boost solution.
Please tell me if I am wrong.

No matter what I do - I'll need an intercooler.
I have a Mariah wide body kit - so I have room for an intercooler.

I imagine I can run in the 10 to 12 pound boost range.
Would that be "safe"??

Some of the suggestions I need are:

I'll need a new exhaust system.
Turbo
Exhaust manifold
wastegate
BOV
Intercooler
Plumbing
Separate oiling system?
Anything else??

Another option I was considering was "Electric Supercharging".
I'll probably get flamed for saying that, but I went through the numbers and it seems there are advantages and disadvantages to this approach.

I strongly believe there would be significantly more power for a given amount of boost.
It would be a much simpler system, being totally "bolt on".
I would imagine cost would be the same or lower.

The "thomas Knight" system seems to be the only legitimate "electric Boost" out there.

But there is no controller yet available.
However he makes a blower/motor assembly available that could provide 12 pounds of boost to a ported 13B engine at 8000 RPM.

Luckily - I can design a controller since I've been a Electrical Engineer in the Military/Aerospace world for 25 years.
Controlling a 36V, 2000A Electric Supercharger is easier than controlling a Missile Fin, and the power levels are similar.
Wastegate and BOV functions would be performed by the controller as well as boost .vs. RPM curves

But - That might be a stupid approach.

I need opinions!!

How much will a good Turbo system cost using new components??
(Including Exhaust system, any special oiling etc)

The "Electric approach" would cost about $3200 + Intercooler.
