rotary starlet

Well today i realized something i dont know **** about rotarys

I need to start doing some research, but while im doing that maybe somone will answer my questions for me and make it easy on me or maybe not and ill end up searching for a day or two and figure it out on my own either way works.

Im looking for around 350rwhp out of a 13bt, my main problem is i dont know who makes good stuff for rotaries what are the good companys, who makes reliable parts. I've been working on piston motors too long, all this stuff is foreign to me but its a huge gap in my knowledge that i want to fill, plust 350rwhp in a 1500lb car is awesome.

Anyways im going to do some more research, im basically just lookin for people opinions on how they would do their motor to hit 350rwhp, as for a turbo im probably going with a turbonetics gt-k 325 or 350, im not really sure yet.

Its not so much the bolt on stuff that really is bothering me though, its the porting, should i get a street port or bridge port.

Man im so noob with rotaries i got my work cut out for me, i feel like a little kid thats learning to walk again.

Cant wait to get teh starlet boostin

If you guys have any answers for my questions thanks for makin my search easier, if not well oh well i just have to do the leg work myself no big deal. Im sure ill have some more specific stuff to ask about later once i fill in some of the larger gaps in my knowledge

That GT-K 350 will be too small for the power output you are looking for. Rotary's are a bit on the inefficient side so when choosing a turbo and choosing a specific horsepower rating you will need a turbo that is approximately 15% more than your target horsepower. If you are looking at 350rwhp I'd look into something like a Turbonetics T66 with a .96 hotside or anything in that range. I like Precision turbos something like a PT67 http://www.theracingstore.com/index....mart&Itemid=26 As far as porting goes a good streetport will work fine for you it all depends on what you want. Here is a good source for porting templates if you want to do them yourself http://www.pineappleracing.com their site is down right now but if you do a search for their porting templates on this site you will get a visual of them. https://www.rx7club.com/search.php?searchid=4182706 Hope some of this info helps you out. Also do you already have the motor in the Starlet? If not you are going to have to move the rack and pinion about an inch and a half towards the drivers side to clear the motor.

nah i dont have anything in the car yet just doing research right now, its running all stock at the moment. Hrmmm good to know about the turbo thing i guess that bumps my size up to a gt-k 450 (those turbos are awesome) and sweet porting templates, ill have to look into that. How does moving the rack affect the car, what exactly would it do besides give me more clearance, how would it affect handling and such. Now i have more stuff to go and look at to get prepared to do this.

Thanks for the help guys.

t66 will be close to 500hp.

60-1 should be around 400 on pump.

friend onf mine dynoed 330 at 10psi on a 57 trim i think.

im not sure exactly but maybe a small GT35R or large GT30 may work for that range.

For mounts and such, talk to Rene and add the big bolt kit from Mazdatrix to your budget.

okay thanks guys, but keep in mind im driving a starlet if im running 350whp all i need to do is have the car fully caged and get a suspension and tire setup that will hook and the car will be in the low 10's i dont need any more than 350 in that car as it will start getting scary really fast, the car is so damn light lol im not looking for any more than 400 and even that is too much. I have low power goals which is the nice part about it.

I just found out a guy i picked up a starlet off of for free has another one going for free (its just a shell with no front suspension or crossmember) and also a 4ag with t50 trans for free, so now im going to have a 4ag in the shell and get it ready for dd while i strip my orange car down and get it ready for the 13bt =] I hope i can get the motor i havent been on the forums the last 2 days and he posted it up late the day b4 yesterday but no one really close has said anything. Now im not going to be able to concentrate at school im going to want to bail early lol. Wish me luck in getting free stuff that should cost me about 1k lol

well i went down there today and talked to someone, he was working on a truck when i got there, he was the taller of the 2 asian guys that works there, i forgot to ask his name but he knew who i was talking about when i told him that you sent me down there lol. He just laughed and said ya we build that guys motors lol.

So basically what i found out is this. I was looking for around 300-350whp from a turbo II motor. He told me i could do that without doing anything more than a standalone as long as the motor was in good condition and maybe do a small streetport to it if at all. He told me he couldnt do anything that required fabrication because he doesnt have a welder but luckily im trying to get certified right now so welding fabrication is no big deal for me. So motor mounts shouldnt be a problem, wacky when you refer to "rene" does he work at sidepex? Hrmm big bolt kit dont know what that is yet ill go look and find out in the next few minutes im going to start putting together a list of stuff i need and ill post it up so you guys can take a look at it and let me know if its lacking anywhere.

That other shell i was looking at getting fell through, i called the guy and i asked him when was a good time for me to come pick up the shell and these were his exact words lol **** had me rolling when i hung up "only you know" he kept saying that and he was so confusing and there was these long like 30 second pauses after i would ask him a question b4 he answered guy sounded all fucked up like he was on something. I've dealt with him b4 when i picked up a parts car from him but he was never that sketchy sounding so i just bailed on that.

Now im thinking though, i wonder if a 13bt might be too much, i mean i could always swap one in later without too much more fabrication if i just went with a 12a or something first right? I would still be running a ford explorer rear end that would be shortened and custom driveshaft. I think all i would maybe have to change to upgrade from a 12a to a 13bt would be motormounts unless the driveshaft ends are also different. I would be able to do the swap much sooner if i didnt do a 13bt i know that much for sure because i could go with a carbed 12a and not have to worry about the cost of a standalone. Stuff to think about anyways, also i have to keep in mind that im on shitty cut springs right now and im going to have to come up with a suspension solution for the rear once i do the ford rear end. At that point i will probably want coilovers but that involves more fabrication and suspension on my car gives me a headache.

mmm i need a job now if anyone knows of any shops that are hiring (unfortunately if it has to do with rotary motors count me out unless they'll teach me. I've been a pistonhead my whole life so far and can build piston motors blindfolded but hand me a rotary and ill just look at you with a very blank look on my face) or need a welder let me know.

ok if i am correct the big bolt kit you were reffering to that mazdatrix sells is actually an oversize stud kit right? Like for example on a piston motor i would go with oversize arp headstuds to bolt my head on in a high compression or turbo application. But these studs hold all the housings of the motor together. Interesting deffinately going to invest in some of those, i never do a motor build without replacing (damn me for using a reference to piston motors again) head and main studs.
