Well i want to build a car that can rev super high 13k+ i was thinking jsut buy a motorcycle engine and build a car around it.. but ill look at my rotary roots first. whats the highest anyone has gotten a rotary up too and with what?

DREYKO

your gonna need to get everything super balenced atkins rotarys supposed to be good for that. forget the stock ecu itll be crap. youll need a sick port to make any power. and a damn good flywheel too, the stok one will seperate. go to atkins rotary, they have into on this

yup, and be prepared to do a rebuild every 30k miles im not saying that to sound like a dick but seriously you will have to do a rebuild every 30k

you can do it w/ rotary, but thats a super race motor that will be hard pressed to make any power up there

I think that would require lightened rotors and some very other spendy mods. Not to mention a peripheral port.
Bridgeport can make power over 10k, but not sure about 13k? No idea what works up there.

Why do you want those sorta RPMs may I ask? Just to have them or with a sepcific goal in mind?
Do 70 in 1st?!

i know the rb flywheel isnt supposed to go above 10k so i dont know what kinda fly he is going to use

gxlbiscuit

no real goal i just want to make some noise with high revs. just somehting to screw with. high revving engines just sound like fun. this would be tracked only. 30,000 is ok .

I see rotories above 12k rpm here all the time, There is one that I am personaly friends with and all hes done to his car is bridgeport it, put a big carb instead of EFI and a magnafuel race pump. O BTW This is his DD. He does low 8's on the 1/8 mile / 13's on the 1/4 mile with toyo proxies. Motor is on a starlet though. Still a 13b N/A and it revs above 12k

and everyone calls me stupid for wanting to run 11's or 12's... damn the flamers damn them!!!

They aren't dumbasses are ******** (well, maybe a few of them) they were just saying that you need to do more research about what is involved in the kind of motor you would have to build.

Why not make some noise with a big turbo? or wide open un-mollested exhaust?

is it really worth the 5k you'll nearly spend on this engine just to "make some noise"? Some noise can be made on a street car that runs high 11's with a monster turbo, standalone, and fuel mods...

I mean I understand the curiousity but is this serious? I could see wanting to build one as a serious race car or as something to prove a port efficeiency at high rpm......but something to "make noise with"......I dunno

well actually I'm a bit curious on that too, I have a '86 FC3s N/A GXL, 33k mile on the chassis + engine. How much would it cost about to keep the engine N/A as well as preferably street legal but boost the redline to about 11,000, well without resorting to an engine swap.

Carzy Driver

an 86 GXL with only 33k on chassis? maybe since the last rebuild...

sintri

as far as I can tell, it's legit, every single oil change recipt on there coincides with the story, however, it changed hands twice before I got it, the second owner didn't really keep his oil change recipts so for all I know he could've added 100,000 miles to it and rolled back the odometer in those 3 years, but doubt it. Only bad thing is the car's been kept outside all this time, so I'll need to replace the front fenders which are showing some signs of rust and give it a fresh paint job.

rx7b13

if you got friends and hella deals like i do it wouldnt be much over 3-5k but if you do every thing by full price then your looking at about 10k plus i beleive

The only reason to rev an engine that high it to make more power. To do that you must have an engine capable of actually making power up there, i.e. massive airflow from huge peripheral ports and completely unrestricted intake and exhaust systems. The only place you'll find a rotary revving that high is in top-level drag racing.

Sorry but this sort of wishful thinking is based on a lack of knowledge and understanding.

This post has proved you belong in that category, since you obviously don't want to accept or believe advice from people who know a lot more than you do.

the guy i bought my car from hits 14k rpms in is 1st gen that runs on 114 octane fuel (or right around 114), obviously not the stock engine.

High comp ftw. Did you guys see the PP 20B? The speedometer went up faster than the tach.

unW7WZ

a british company used to build rotary motorcycles....buy one of those and you're done...17000 rpms...

Norton was the british company...just found out that suzuki and Hercules (?) used to make some too...

Edit...WOW...I want one now.... LOL

Dumbasses? Coming from the guy that doesn't know anything about what he "wants" to do but sure likes to talk as if he does, that statement is funny.


To the original thread starter, 13k+ is going to take a TON of work and a TON of money. Especially to even make useable power that high. I think a goal of 10k rpms is much more within the realm of possibility.

i don't think the flame fronts move fast enough to make power that high up, get a turbo

rx7b13

im always looking for advice thats why im on here. its just people dont have to put other people down and make stupid comments about what that person wants to do.


all i asked is if could be done. thats all, all i needed was a simple yes or no

Iketh

then your question should have been "can you make an fd intake bolt up to a p-port?"

you would still sound retarded but your answer would be a clear "no"

t-too

I dont see any point in making an NA pp when turbo power comes so much easier... especially after watching that video of that orange fc with the turbo pp 20b... mmm eleven grand beastliness...
