Im thinking of spicing up my ma70 a bit in the near to distant future.

Never heard of that working properly.

Because i have rebuilt the 7mge, i also have had the block shaved about 9 tho, and unknown for the head. This has obviously upped the compression ratio a "bit"

Having said that...im wondering what itd be like with a supercharger on it? I wouldnt run into the same heat problems with turboing it. And Performance wise about the same?

Why wouldn't you run into the same heat problems? Compressed air = hot gas.

Size for the blower? - A toyota SC14 would be too small im imagining? I was offered a 3.8 Commodore blower a while ago for $400, and thought it was reasonable. They are a reasonably sized unit.
Has anyone ever done this? Or done some research about doing it?

Haha.....i wanna see you fit the commonwhore blower...where do you intend putting it?

Id be looking for about 300-330hp.

Why bother with a 7m.

now now mate dont be so harsh lol!
Seriously...computer option would have to be a motec?
Heat problems from the exhaust gasses running the turbo would surely generate much more heat?!
Commodore blower is slightly impractical...my bad...they are a bit too long shafted!

You can run any computer you want in reality.....depends how you want the car to run 
Yeah long shaft and perhaps thinking where the hell you are going to mount the thing short of a total custom plenum inclusing relocation.
centrifical blower is your friend

other than the sake of 'cool' factor, why would you bother?
Get a 7MGTE, put an exhaust from the turbo back on it, get a good cooler (ARE), do the headgasket properly, get a FCD and run about 14psi. You'll probably make close to 300HP ATW's for ALOT less than sticking a blower on your current motor.

How well was the motor put together? Put a shot of NOS down it's belly, that'll get it moving

I hate to be critical of everything you post.. but this is a shit idea
It will be very expensive, difficult to set up and then you don't really have much of a guarantee that you'll get a good result.
The Commodore blower is too small, old man had one with all the basic mods (extractors, twin exhausts, air intake, chiptorque chip, lower diff gears) and it was still slow - less than 200rwhp in fact.

If you want to keep your freshly rebuilt engine and want a bit more power, just get some GTE turbo gear and bolt it on; the NA-T route is well documented so you won't have to do figure everything out for yourself through trial and error (always an expensive exercise). With low boost and appropriate fuelling/ECU mods it will go very well indeed for relatively low cost. Getting the same result out of a blower will be much more expensive.
FWIW I have a spare GTE manifold lying around, and I'm sure you won't have much trouble finding a second-hand CT26.

Shaving 9 thou off the head will barely increase compression.
Bolt on all the 7MGTE gear. Have a chat to marty from these forums - he did an NA-T conversion - and also scour the supraforums.com website. A few guys there did the 7M NA-T thing.
Way cheaper and easier.

I don't like the look of that loooooooooong unsupported belt to the blower
The current editors "Project Sleeper" car in Zoom (MX83 Cressida) has a N/A motor with a Turbo and it seems to be living OK.
I agree with GT, Norbie et al. Let it breathe a bit more (as per Ed_MA61, or go the turbo route. Too many people try and re-invent the wheel and after a lot of expense and time still end up with a wheel, but only a different colour

as i said it is all just ideas atm, so out of curiousity i thought id ask about the blower route.
But if it seems cheaper, easier and more effective/efficient im leaning towards the turbo way. What kind of hp can i get up to with a toyota 7mgte computer?

GT...The 9tho was taken off the block to make it an even surace again. Id guess the head wouldve had about 15 taken off it.
Total of 25 tho...this wont affect the ratio much?

Nope. I got badly stitched up by work.
PersonX rostered for the weekend was sick on Wednesday. Main office calls and asks if the personX is sick on Friday would I work. I said if PersonX is sick (like hospital sick) and they couldn't find anyone else, then I might consider it but that I would need to know later that day as I had plans for Friday (driving to Dubbo). No phone call from main office and I get the answering machine everytime I call.
Thursday, PersonX is at work. PersonX rushes over to me and says, "Thanks for working for me tomorrow."
I said,"Er, no, not quite right. I'm off to Dubbo tomorrow."
PersonX said,"I'm on a plane this afternoon." Me angry.
I try to ring the main office and get the answering machine.
I had to work Friday. I was wined, dined and bent over the bonnet of a car.
However I didn't know for how many hours I was supposed to work as they never rang me to confirm my start and finish times. So I slugged work for a 14 hour shift at double time and a half.

blake, i have to agree with these guys actually, stick with the GTE conversion - its tried, proven, and makes good power. if you run a low boost setup with intercooled idea, and stick to PULP dishwashing liquid at best you'll keep things in check.
that said ;
an sc14 pushing a very small amount of boost into your 7M will be working very hard - if you don't intercool it, you'll be pushing hot air temps into your engine, which, won't be very beneficial - i know the commodore fraternity have done this with limited success at b/w 2-4psi - hardly worth it.
those pictures of the eaton m90 series blower, sure, look nice, but, thats a big belt and i don't spot a belt tensioner, and, again, what about some form of intercooling.
whilst a PD blower can displace some air from 0 RPM, it does get inefficient up top, and, if not intercooled, your power can go backwards depending on your application at high RPM - a turbo such as a CT26 suited to the 7M will help avoid this.
FWIW kristian from japanese imports has a whole heap of 7M turbo gear available...
