high reving NA fc vs. a TII

[oni_roh-FC]

i am in a lil perdicament (spelling) i want to make a streetable drift car and i have a atkins 13b rebuild stage 2 porting and 3mm's. i can turbo it (oem at first) then a t3/t4 or i can make it like a indy car all revs. what is your hypothosis. much apreshiated (spelling) the engine is out of the car and i am about to do the fuel rail and intake/dynamic chamber and i will need to replace it if i want to turbo it. i should of told you this earlier. gomen

[nissanguy_24]

The higher up your power band is the less streetable the car. And most amature drifters like a "streetable" power band for drifting and moutain running. However i will ask you this.. is there some reason you cant make the Turbo Engine rev like the NA engine?

[URMachines]

well if yuo want to rev to x amnt of rpms, you need to make power that high, regardless if its NA or turbo. say 9000 rpms. you will need a nice race port to make na power that high but low-end will suffer. same for turbo. i say go turbo, its easier to kik out the rear end.

[driftfreak]

ok wheres the thing about rotories
there are no cams to replace. there power depends on the size and shape of the ports on the motor.
if you want a high winding motor your going to have to do some serous porting on an NA or Turbo 13B
and sence there is no diffrence in the mass thats spinning between a NA and turbo(unless you have the new rotors out of an RX8) then it just depends on the CR of the rotors that are in the motor

BTW which rotors are in the motor now?

[oni_roh-FC]

the equivalent of the renisis. light weight rotors with 3mm apex seals. and the problem with rotaries is that the cas can't keep up with the rotaries capabilities, as the 9600 rpm rev limitor. and when it gets up that high the spark plugs won't fire. and when the revs are that high the turbo won't be able to put the amount of boost to keep it going, so it will bog out. i am pretty new at this so everything i just said is what i experianced with my fc and my friends and to anwser another question its is quite massivly ported.

what series motor is this, S4 or S5?what else has been done internally? upgraded bearings, oil mods, e-shaft? all these need to be addressed if you're going to be revving 10k+rpms and that's if you're even power up there.

[driftfreak]

along with a decent porting job on the 5/6th port...
are you running with a stock ECU or what , cause you might be running in to the rev limiter

[oni_roh-FC]

i really feel like i am repeating my self. i was asking for everyones opinion on which would be a better drift car a high reving fc or a turbo fc. i noe everything i need to do to make it either one. i was just asking since everyone on this site lives in socal and so on which do you see more often a turbo or na. that is it. and my internals are stock except for the rotors and it is a gtr-13b not a gtx-13b. and yes my ecu is stock. please read through this thread and everything will be awnsered if not please ask again. lol

[theflatlander]

for a streetable drift car i'd go turbo, i'm know with a hi revving n/a things would be fun but just wouldn't be as easy drive on street.

[Xantos]

i'd say go NA, only cuz i'm tired of seeing everyone and their mom get turbos. Not that turbos are bad or anything i just love people that get the same amount of power as a turbo yet they are NA, there is a certain sense of pride in that. On the other hand, this is your car and you can do anything you want with it but in my opinion try and be a little different!

[Feint]

Turbo would be easier.To rev higher requires internal work,are you willing to pay the price to play? I've heard of rotaries being spun upwards of 18,000RPM's in some cases.I guess you can pretend to be Michael Shumacher minus the sequential transmission.

[spock]

No one should care about being different. I say go with the turbo. High-revving cars aren't that great unless you plan on doing road races on a track. Turbo cars usually have a more usable powerband, which is something you definitely need for a good drift car and a fun daily driver.

actually i heard that the lemans 4 rotor got banned because it was able to be spun at something close to 40,000 rpm's i dunno if that's true or not but if it is... wow, rotaries can be spun as fast as you want them to as long as you heat treat everything, cause if you don't blown apex seal, now to get on topic, i'd say go NA, you'll have a predictable powerband, whereas i've seen lots of rotaries with turbos that have trouble with when they spool, they sometimes kick in at different engine speeds, not good if you're trying to do precision manuvers such as drifting

umm.. no the 787B Lemans car was banned due to the engine and not being able to really figure out the displacement of the motor. and redline on the r26b is more like 10k rpms.

[Ghost of Duluth]

If you know how to do either one then you shouldn't care how many people are running what. Do what you want to do.

[Raziel]

I have friends who own a N/A FC and Turbo FC. They both drift the same. If the car was originally a N/A engine i would keep it that way. I would spend the extra that you were going to toss in for a turbo for something more useful in drifting. Like suspension or LSD. Also the N/A FCs last a long time unlike the turbo models. Once you start fixing up your car its hardly streetable.

[TP | sil-beer]

yah....i dunno tho...Na and turbo FCs dont really drift the same imo

[marshun]

they sure dont. the turbo FC is way better. and im pretty sure all the turbo FC's came with lsd. (im rusty with my FC knowledge)

but a NA FC doesnt compare to the turbo FC. and about the power band, its a rotary, even witha turbo theres a nice power band in there.

[mrjuwono]

I heard that the higher compression rotors on the n/a would not work well with a turbo. I heard that to get more power out of a na engine (aside from exhaust, headers and intake) you should convert it to a carburated engine (i.e. holley), upgrd fuel pump and upgrd the spark plugs. Other than that, the folks at Racing Beat suggest going to a turbo for power over 250 hp.

Honestly, I think the na FC is pretty good to learn on. It enters turns quickly so you can initiate a drift sooner. With a turbo, you're required to keep the turbo spooled up for power and I think that for attacking a large track the power will definitely come in use. So I think you should keep it na and fix up a turbo model if you plan on going pro.

Good luck!

[PRC]

Any of the two engines will work fine.

I would go with an N/A 13b given the propensity of turbo rotaries to blow up.

Any of the two will require good amounts of cooling system mods so you dont blow your seals.

Ummm drifting wise it compairs. Some N/A models Came w/ LSD too. I also believe the N/A model is lighter than a T2. I know a carbed N/A is for sure lighter. If you havent driven one or the other how can you say one is better than the other?

[Feint]

The 12A makes what,135hp? NA rotaries have no torque.If you were to go the route of turbo,your best bet would be a T2 swap.The NA model engine comes with a weaker transmission and doesn't like to have air stuffed down its throat..I'm not sure if a 13B-REW swap has been pulled off in an FC,due to clearence issues,but that would be pretty cool.

NA rotorys have no torque???

errr have you ever drivin one

they have more torque then turbo ones silly

It's still not a lot of torque....

Not everythings about torque. If it was every US drifter would be driveing a domestic.
