im with sideways7.. i wanna maximize my NA right now.. i have rb header (still using a bonez cat) and a custom set of pipes from there on back... i really wanna get the engine ported but i dont know of any good rotary shops around trenton new jersey.. once ported i wanted to get a cone filter and safc (eventually standalone).. but thanks for the help .. i was just looking for some ideas and you all have helped a lot.. what port do you suggest though??? and does anyone know where i can get it done? thanks

Well, if you want 200whp, you have to have a port. I would recommend getting a largish street port, as it will give you more power but still keep it drivable and reliable. You can get more power from a bridge, but they tend to not last as long and hurt drivability.

MAN, Sonicrat is hatefully on point in this thread....

Theyres too much to quote but here:

I have had a hundred wild planned out ideas for ym car and this forum and some recollection time made me regret them all.

I was so excited to have my n/a fc then after a few weeks of driving ti i wanted more power and tarted my "beefy n/a" plans. Once i realized the ammount of money and crap involed in getting anything out of a n/a(very little), i decided to go turboed n/a. i realized in the middle of that rpoject that i dotn know enough about what im doing to practice on something i cant afford to replace.

If some guy (mentioned earilier) did a v8 swap because he blew 4 motors, he should have stopped after the second and used all that extra money to let an experienced tuner handle his car. End of story.

Tuning shops exist because 90% of owners arent professionals.
Kevin Landers is rich because 50% of them think they are.

how would one go about making a turboed n/a??

Mordachai

ya know, I used to want my engine to pop just so I could rebuild it, mild p-port and beveled rotors and balanced assembly......

right now I need the car for dd trans, and am hoping the engine holds...

werd. You ever get your m/o? Haven't heard from you in a while

Turbo is an over all better option if you want hp.

Turbo's can be modded easily
Turbo's have plenty of aftermarket parts

A simple injector swap and Rtek will get you 200rwhp.


Now I still have a small spot for NA in my heart.
I like the power curve and the simplicity/reliability.

My dream car would be a SP or BP 3 rotor NA.... Decent power with some reliability and torque!

check your pm's

sublime42o

Hey what a coincidence. I haven't heard from YOU in a while. I hate to jack a thread, but you need to send my fuel pump already, I paid you nearly two months ago and now you've haven't answered my PMs in a week and I see you posting everyday. Kind of makes one think... wtf??

Haven't gotten a new PM from anybody prior to Brklyn since the last time I messaged you, and as I said then, it went out on Tuesday

sublime42o

well if you had actually told me it went out on teusday, that would have been helpful. I PMed you 3 times since the 17th.

done hijacking this thread.

It makes me laugh how 200rwhp is seen as some sort of NA rotary holy grail. It's ridiculously easy to achieve that, and it's it's not even expensive. There have been 200rwhp NA rotaries on the the street for 20 years in this part of the world. All you need is bridgeported engine with a Weber carb and manifold and a decent exhaust. Sure it'll be pretty loud, have horrific fuel consumption and terrible low-load and low-rpm drivability, be totally illegal and probably uninsurable, but you'll have your desired peak power and it can be done pretty cheaply.

Why is everyone so obsessed with peak power? Is it just bragging rights? Engines with a high peak power figure don't make good street engines. If you want a race engine, go build a race car so the engine can be used properly. If you want a fast steet car, accept the fact that sacrificing some peak power will result in a much more flexible engine that'll give you more performance in the mid-range where so much street driving is done. Or get a turbo...

Ever owned a properly sorted turbo car? Ever driven one? Even with an upgraded turbo, spool up is extremely easy to predict (and takes about half a second). Turbo lag is insanely overrated, you just have to keep your RPMs up and you'll be fine. Plus, a turbocharged rotary is a ton of fun.

That's a good way to think if you want to throw a ton of money at your car and not have that much to show for it power wise. Sorry but that's the sad truth.

They did have a reputable tuner. RX-7's don't really appreciate knock yo .

His RX I beleive made like 430HP with numerous modifications.

What did you dyno at again?

Jager

That is true. I didn't want to go turbo at first because I wanted power and reliability. NA's can become 'quick' but nothing mind boggling. So then my predicament.

Honestly a V8 may be the best route if you want power and reliability .

Well, I'm going to spend about an extra 400 bucks + tuning to get my car where I want it. I already rebuilding it, I'm just doing it with the stuff to get good power. I'm not shooting for absolute power, just good overall. I already have the ports, and am getting the s5 stuff for free (hopefully), so all I lack is the standalone. I'm going to get a MS once the engine is brocken in, so thats that. I would like to hit 200 rwhp, but if I can't, no biggie. I'm not throwing money at it, just doing it right the first time for a little extra money.

Yo! Sideways7...I was considering the same thing S5 VDI Streetport maybe some Pineapple sleeves. Megasquirt & maybe some water/methanol injection & NO2 for some extra punch. I have '88 s4 NA with RB exhaust that needs a rebuild. I had considered RX-8 rotors but am not so sure now. If I really wanted a turbo car I'd probably just buy one.

I'm not really planning on running nitrous, though I may do it at some point. I'm planning on just enjoying my car however it turns out. As I said earlier, I'm going to save up and get a clean GXL with a blown motor and swap in a 13B-RE with a GT42 or similar. Thats going to be another 4 or 5 years, though.

Or you can do a streetport, keep stock ecu, get an s-afc and someone that knows how to tune, and make 200rwhp... Does no one read what I post?

ok... a Driveable streetcar with a nice useable powerband somewhere in the 200 RWHP range is what I would like to get out of my NA s4. I have the RB RR exhaust & K&N filter. So I would need a street port, VDI and some way to tune it(megasquirt & spark?). Maybe upgrade the fuel pump & FPR. So I figure that would maybe cost $1000 more than a regular rebuild. Would S5 rotors & internals help much or raise the red line/powerband? I'm not really interested in swapping drivetrains & lugs & rotors.

BklynRX7

please dont put water/alcohol injection on a n/a vehicle.

ddub

Rebuild with s5 n/a rotors, well designd and good sized streetport, vdi is not necessary and the n/a manifolds suck anyways, at least an s-afc, and someone that is competent at tuning. If you are shooting for 200rwhp you might as well get a TII or FD fuel pump and TII injectors to put in your secondaries, FPR is not necessary.
