Gee, that wasn't late or anything

tjeter

so whats hte update i just read all 7 pages and im very curious what he hit on the dyno..

Tech_Greek

At least someone thinks like I do...

ddub

There are plenty of people trying to think differently, stay n/a, try other things. I'm personally shooting for 230+ at the wheels with NO boost or nitrous. So what?

Kahren does experimenting and stuff all the time, 88IntegraLS is building a custom SC setup... etc. Many people are trying new things and being "different."

i would stick to turbo!!!!

Nothing quite like a rebuilt engine that makes more power than the supercharger kit does, for damn near half the cost of it!

Anothing thing of note, is 'decent' is pretty relative, I don't consider 230 very decent, to me that's just like your everyday stock sports car.

ddub

Yah 230 isn't anything special, but it's a goal I have. I still say a 230rwhp, 10k rpm revving, lightweight rx7 with nice suspension could be quite a fun ride. That's what I'm shooting for personally.

Tech_Greek

Ummm how about a big **** you?

I wasn't crying a river you dumb ***, I was just stating that there's a lot of mindless turbo owners running around thinking it's the only way to go, it's something different for a change I'm glad to see someone thinking different.

Actually an N/A rotary lasts a bit longer than a piston engine. I've heard stories - outside of tweak-it-out forums like this mind you - of NA rotary engines lasting "forever". "I still have my RX7 but my Civic went kaput", "I never had any problems with my high school RX7, but I had to sell it since I got a family", "I'm thinking of putting a roll bar on my high school 1st gen and giving it to one of my kids", etc.. The 1st and 2nd gens have a VERY high reputation for reliability, except among those who get swayed by the early experimental rotaries and the 3rd gens. From what I've heard a well maintained, unpushed 2nd gen NA engine goes about 250,000+ miles, and even then the owner often got rid of it for another non-engine related reason. However a mechanic told me he gets a lot of rebuilds around 160,000 miles. So it depends how you treat it.

Twin Turbo 3rd gens on the other hand...

I mean, how fast are you really going if your car is in the shop or on the side of the road? Build the NA man!

It's not all that difficult to build a reliable turbo either. Also, the simple fact is, if you want any ammount of power that's somewhat usable on the street still (I know, some people drive pports daily, but still, not exactly something that'd survive houston rush hour very well), a turbo is the best suited for the rx7. Yes, some chargers work, but they're really not the best option in any aspect except for the unique factor, (a properly sized turbo can produce more torque through the entire band than any dyno provided yet of a supercharged car), not to mention it's ability to go far beyond the chargers.

sounds like alot of work for not a lot of gain to me, but a cool project none the less, (ive always wanted a renesis powered SA)

A boosted engine naturally doesn't last as long. All that forced air puts more stress on it. Sure, you can make up for it in other ways. Just like Fritz is making up for the lost power of a turbo in other ways. But there are limits to both making a fast NA and a lasting turbo. And for both goals putting on/taking off the turbo will make a difference, even (read "especially") after all the other mods.

160k is good enough for me

ddub

Haha

That's more than enough for me considering I'd probably bet bored with whatever setup I'm running by 30k and want to try something new. I get bored easily and keep wanting to try something new, different, new style, etc.

SonicRaT

iTrader: (6)

Well, I've put 160k miles on a rebuild that was pushing 350rwhp daily driven with no hiccups, then i sold it.

Maca1ino

yeah, with T2 rotors running low compression, you can almost hang with civic ex's

haha, i just happend to look back at this thread and saw the reply...better late then never right?

here is the dyno thread

I dunno, sometimes never is better, especially when it comes to something dealing with Cartmil

tuffguyno1

I have a 1990 gtu n/a. It has a streetported motor, no airpump, no cats,no 5th 6th ports, no ratsnest, 2.5 single exit exhaust with header and presilencer, short shifter, efan, ported manifold, and it will get up and go. that is with high compression rotors let me know how the low compressions tii's do.

Hmm very interesting thread, but why was it dug up.

Jager

iTrader: (10)

Probably because he wanted to prove that a NA can make power? Did you read the thread about people beefing up their NA's and the **** that everyone needs to go turbo?

Don't make smartass remarks and learn proper grammar.

noman17

this thread is fun,
the power made with t2 rotors was less than one with regular na rotors, frm another car that kahren tuned also,
they were both n/a with standalones, intake mani was the same too both t2 mani,
this motor is a 4 pot the other a 6,
now the wonder is how would a 4 pot motor do with na rotor? it'll prob be similar to the 6 pot one
