Turbo rotors any different from NA rotors?
Hey all
just as the question asks are they different besides compression? because my idea is that i take my NA rotors and put them into the 10AE that ive found for a bit of extra kick you know? take alot of the hassle away of having to try and get different parts for the na to make it more like a turbo, when i can just start with a turbo. |
Other than compression yes they are the same provided you use the correct counterweight. Just remember if you're using n/a rotors in your turbo application you will have to have better tuning, more fuel, and run less overall boost unless you're going standalone. But lower boost isn't a big deal since higher comp with less boost will make the same power as lower comp with higher boost.

s4 rotors weigh the same, and the 2 differ as far as compression. s5 rotors weigh the same, and differ as far as compression. s4 rotors will not work with s5 counterweights, or vice versa.

Theres a few guys on here running the same if not more boost with NA rotors than some of the TII owners here.
Its all about proper fuel delivery and intercooling. |

Im pretty sure, but uh don't slam my ass if im wrong ok? ;)
Check that thread that was floating in here a few weeks ago titled along the lines of 'na guys, how much boost you running'. Its in there. Of course the SAFC is needed, its impossible to get those numbers without some kind of fuel controller. |

Ignition timing and fuel are going to have to be right on. Many people on this forum tried to tell me not to do this high compression turbo motor, it will make more power with the same boost but detonation risk is very high. I would have someone very experienced tune it before boosting, otherwise the rotors will work but i would use the counterwieght off of whatever motor you take the NA rotors from, good luck with this project and let me know how it turns out i'm a very big fan of high compression turbo motors. (just a little side not i felt like adding: A buddy of mine had a iron sleeved and fireringed K20 acura rsx block bored and stroked to 2.2 liters, compresion was 13:1, he ran 30lbs of boost with race gas and put down 583hp to the wheel before tuning the standalone and also without his 250 shot of nitrous, but like I said tuning is very important and on his second dyno pull the motor blew a new motor being built now, just a little story about how much power high comp turbo motors make.)

That link is for a turbo'd NA engine. The original poster was asking about stuffing just the NA rotors into a turbo 13BT? -Ted |
^ Ted, wouldn't that be BASICALLY* the same idea, just the port timing is a little different and you already are set up with the TII crap that isn't with the NA? I mean, theoretically, and a big theoretically at that, you should be able to do it with timing and fuel dead-nuts perfect running the stock boost level. In reality, I wouldn't do it without at least a Piggyback, preferably a full stand-alone with it properly dyno-tuned.
I guess the question is, wouldn't it follow the same basic theory as turbocharging an N/A? *in caps to point out that it is a basic idea, not sarcasm or anything else |
well why i want to put the NA rotors in an turbo motor and car it would make my life SO much easier, because i dont have to play with pesky manifolds machining or any of that tough stuff. i can just put higher comp rotors in the engine and have everything line up as if it was a normal TII.
And dDub you say to put the correct counterwieghts, which counterwieghts are these? ones from an s4 turbo? or the s4 NA counterwights? and as far as standalone goes what would you na turbo guys recomend? as far as economy and tuning options? |

and standalones? what do you guys reccomend? |
Tool to hold the rotor in place? You dont need anything special to assemble an engine. I don't even use rubber bands during assembly like a lot of people. I'll give you a hint...the easiest way is backwards to the FSM method.

and thanks for the tip |
