Well I registered the 7 on Wednesday and I've gotten to drive it 2 times allready. It's fun driving it but I don't like how it has so much play in the steering wheel at high speeds. It also needs more power I think, so this winter after I get some money saved up, I'll be having it rebuilt with a street port job. I'm hoping for 200+ HP, if that is achievable with a street port.

Which place is better to send in my engine to get street ported?

-Mazdatrix

-Rotor Sports Racing

-or any other one that you can suggest.

I'd like a pretty extreme street port. I'll also be using a 48 IDA carb. Street port exhaust, underdrive pulley's, ect.

 

It all comes down to how much money do you have. To port out the engine, you will need ot have them rebuild it as well. Personaly, I would talk to pinapple racing. You will also need a different carb, exaust, and possibly a new fuel pump. You can't just port out an engine and expect it to work with the stock stuff.

EASIEST way to net 200 hp is to get a turbo engine and swap that in. 200 on a N/A engine won't be easy, or cheep.

 

I'd think that'd involve porting to the max, nice carb, tuning, intake manifold, custom CAI setup, alternator upgrade, AC delete, new radiator, exhaust header, cat delete, muffler (RB of course!) lightened flywheel, gawd there's a lot to do for that 200hp.

 

Yeah, I know they'll have to rebuild the engine before they can port it. I've checked both sites (Mazdatrix) and (Rotor Sports Racing) a few times and they say they can only do port jobs on certian engine stages that they rebuild.

I didn't say anything about having a port job and everything would be good, I know that I'll have to have a different carburetor, exhaust, fuel pump, underdrive pulley's, ect in order for it to work.

 

It does depend a lot upon how much money you have to spend, but its definitely doable on an all motor powered FB. You'll also need to upgrade the ignition, for the record.

However, either by putting together a turbo setup for the 12a or buying a TII engine will be the easiest, by far, way to get 200 horsepower, and by going that route you're horsepower rating is pretty much only limited on turbo size and port size after that.

If you do massive port work to get 200 horsepower out of the engine, you will be looking at some of the biggest ports you can go for a regular street port, and that's not easy to do at all, or a bridgeport. A bridgeport won't be that driveable on the street because of the amount of revs you'd have to go through, plus all the parts necessary to make the engine last at 11,000 rpms. Most expensive route is actually to make an all motor rotary.

Go forced induction, and I even say go with a TII swap if you intend on spending the money. It will cost the same as a rebuild kit to begin with, and if you do all the work yourself it will only cost you around 2-3,000 dollars in the end. You can do a streetport job for cheap, but if you have someone else build the engine you will be looking at 1,800 probably.

 

200 hp, NA 12A is brigdeport territory. Not that much fun on the street, I have one. Install an S4 TII, do minor mods, you don't even need to open up the engine, you're there easily.

Not only do you need the supporting mods for the engine, you also ned the supporting mods for the suspension and brakes.

You can go about this one of two ways. Set hp goal, build a budget around it or set a budget and get the most hp you can for the money. Going from the 12A 1/2 bp to a 400 hp TII is going to cost me at least another 4k in parts. I aready have a rebuildable TII engine, tranny, driveshaft, and 3" exhaust. I need to upgrade the tires. wheels, front brakes, again, buy a rebuild kit, bigger turbo, exhaust mani, intercooler/piping, injectors, fuel pump, standalone, yada yada yada. All these expenses are for parts only, the time and labor is mine. That is the only way I can do it as cheaply as I am.

 

Supposedly, Chuck (from here in Indiana) has a massively streetported 12a making 225 wheel horse. I thought it was bridgeported, but he says otherwise. He is kind of out there though, so who really knows if it is bridgeported or streetported.

But even if it is a streetported 12a, that thing would be so unfriendly on the road it wouldn't be worth it in the least. And as Trochoid says, 200 N/A horsepower would be bridgeport territory because even if Chuck's is a streetport, it would take a hell of a lot more talent than the majority of people have with porting rotaries.

And either way you should definitely listen to trochoid.

 

not to be dissin people too much but Chuck is Really out there to say the least he just kept giving me crap about how i should not do anything to my car and store it to keep it nice bs these cars are meant to be drivin.

as for porting and all i just think that an engine swap would be the most streetable if youre going for that you can find engines for dirt(thats how 240s and silvias get so much power) if you know where to look. have it rebuilt and do a conservative prot job and turbo it who knows even a twin turbo could fit if you have the skills and then your probalbly beat all imports
after all that who can say there import red lines at 9-10k rpm with usable horsepower

 

Yeah, I really can't stand being around Chuck at all because he is so out there.
