you can, if you want some more easy speed, strap on the turbo setup from a turbo II onto your N/a motor. I have done it a couple of times already and it's pretty damn fun and I haven't had any problems with reliability. You can use the top mount stock intercooler as a front mount, it's very easy and there is plenty of room. You should be able to get the piping done at any muffler shop or Ricer stop.
Keep the boost at under 19 l pounds if everything is still stock.
I usually find complete TurboII turbo setups for about $350-500, so don't think you need to spend an arm and a leg. Good lucjk and have fun.................

If you keep the primary and secondary ports small, you can port a lot of intake duration into the ports, creating an extend port basically, but you will still have more torque from 2500 rpm on up than stock ports if you tune it with an SAFC and advance the timing slightly. Don't remove the 6th port sleeves or actuator, just port the sleeves to match the larger aux port. If you remove them, power below 4k will be dismal. My secondary and aux ports open about as early as possible before losing support for the front edge of the opening side seals, and the car is VERY streetable. The torque down low from about 2k rpm on up is very satisfying. The nice thing about "extend" porting (meaning going for a LOT of intake duration) is that the power just keeps on going and going from 4.5k on up to 8k rpm.

When I ported my secondary and primary ports, I didn't port down at all, just the opening and closing edges.

Umm, that proves I'm right.
13B N/T 89-92 9.7 4328 9.54
13B Turbo 89-92 9.0 4328 9.54

See how the S5 N/T weighs 4328 grams, and the turbo weighs 4328 grams?
That means they have the same mass, b/c they have the same number.
The only difference between the two rotors is their compression, not their weight.

Maybe you should learn to read before you tell people to shutup. Way to make yourself look like an ***.

hmm sounds pretty tempting!

casio

so youre telling people to run a stock t2 turbo on an n/a at nearly 19 pounds of boost?? and with everything else stock? just strapping on the turbo and turbo setup?? hrmmm...

scathcart

Well, besides the fact that the stock turbo eats itself at a mere 15 psi... nine is next to zero on the keyboard.
He meant 10 psi.

If he meant to type 19 psi, he's lying.

andrew lohaus

hold on guys. we have established that all s5+ rotors have the same weight regardless of compression. HOWEVER, since the "tub" has to be shaped differently to acheive a higher compression, this would lead to rotors with diferent weight DISTROBUTIONS and possibly different rotational inertias which is what matters most when trying to balance a rotating assembly.

this would probobly only throw the balance of a bit, if at all, but i'm going to hold out on agreeing that it can be a direct swap for n/a rotors in a 20b until someone builds one, sticks it on a balance machine and it comes out with an OEM level of balance.

maybe mazda thought of this and re-aranged the internal parts of the castings of the rotors to yield the same RI regardless of compression, but hell iduno...

or am i just being paranoid?

I love how somehow every thread about making a fast NA ends up in arguement's, and talk about superchargers and turbos none of this talk is gonna help the guy who started this trhead make a fast NA. For the guy who started this thead, sorry i forgot you name by the time i got here, If you wanna go NA then you're gonna have yo decide if you want it really fast or streetable, cuase yopu really can't have both (depending on what you call streetable),, fastest would be a Periperal port witha stand alone ECU (haltech, Microtech, Etc) But you best bet for a fast streetable NA is still gonna take money, i'd say a rebuilt S5 motor with a big street port maybe a bridge of half-bridge, the exhaust you have should work, and a standalone. But then again you can beat a stock tii with only bolt ons, it's not easy but can be and has been done

I apoligize for the typo.
I meant nine

TurboIIGuy

I meant nine, not nineteen.
I don't lie, I just misspell, LoL

The eccentric shaft doesn't care about inertia... it cares about balanced mass about its center. That's how you balance the rotating assembly... the e-shaft is balanced using bob-weights replacing the rotors.

Please keep this thread FRIENDLY. Any arguments and flamming will result in deletion, which I would rather not do because there's a good bit of information here.

Well he will never beat my AE TII with his built NA! Just kiddin Bobbie. My friend started this thread, so i thought i would check it out and see what kind of responses he recieved. Either way the car is going to get built right, since he recieved that S5 NA FC from me. It was hard to let the car go but it has gone to a better place now. Plus i still have to get my AE TII running myself, so we can go tear up the streets together. Well hope to see some good advice about building a fast NA FC from you guys on the forum. Later bobbie

and now, in 2009, i'm buying the car from my brother and hopefully we'll actually get this thing built.
Sadly, not going as ***** out, but funds being limited it'll still be a step up from my n/a.

can we just agree to disagree to swap a turbo and be done with?
