intakes on the non turbos are a fast was to check if its a s4 or a s5. their completely different.
or the rotor housings. s4 do not have knock sensors, the s5 do also the s5 have different bumpers and front turn signals and the sexy rear brake lights.
i have a s4 convertible but im in the slow process of converting it to a s5.
check out my profile i have some pics of it all.
have fun and welcome to rx7club its the best forum for me it always answers my questions.

I'm used to it by now. Not many women work on cars, let alone their own. I'm pretty new to Rx7s and have a TON to learn. I tried the FAQ section but I didn't find anything other then question on how to post, etc. I'm still trying to figure out totally how to navigate this site. I believe I spent about 2 hours searching for my answers through the forums and came up empty handed so I figured I'd just post my question for a more speedy solution so I can better accurately search out other issues I'm having.
So far what I've got is a nightmare of an exhuast leak issue. I'm thinking about giving up on the manifold and it's flange and installing a header.
I've got a bad/loose ECU ground under the manifold causing my 38OO rmp stall and causing my radio to loose ground intermittently.
A vacuum hose leak SOMEWHERE that you can hear discharge when you shut off the engine.
Then when I've got my functioning affairs in order it's time to repair the damaged caused by running into a tree.

Sound like an/or a battery ground.

thanks Ryan for the help. I actually found that site already searching the forums. I cleaned several of the grounds a while back and it mostly fixed some other electrical I had going on. I fixed the ECU ground yesterday, but it didn't do anything with my hesitation. Pedal to the floor in every gear it gets to 3800 and the primaries cut back but the secondaries aren't coming on (i'm sure...haven't tested with LED). The car climbs passed 3800 but really slow; no boost. I found I missed the ground on the bottom of the shock tower. Going to clean that today and see what happens. Maybe adding a wire from the negative terminal directly to the ECU ground??

I had the 3800 once on my vert, finally ended up sending the injectors to witchhunter to get cleaned, and it showed some of them had been clogged not giving enough fuel, worked fine when I got them back in the car. Not saying its your problem, but noone had mentioned it yet.

I'm probably going to be posted a thread about this. I'm so confused! I have serious electrical gremlins all over this car!

Well my car has transformed in the 2 years I've had it with the stock engine in it. So now the only hesitation I have is from idle to 3000 RPM and after that it pulls hard depending what gear I'm in and RPM range I'm at. If I went back to Vegas from California my car is a hell of a lot lower my car hates that altitude. I couldnt do over 115 in Vegas but I got it to 130 down here in Cali...

There is a thread I ran into on the forums where someone was talking about hesitation before 3K, you might be able to find it.
Hope that helps.

S4 With a RB S5 Race Header no cat straight pipe 3" single exhaust, Cone Airfilter on my MAF. No Sleeves in my Aux. ports so I have to leave harder 2000 RPM to get rid of my hesitation problem TPS and MAF is good. I have no back pressure or low end torque. I have no problems in performance, besides needing a rebuild and car is basically good.

I have a lot to learn!!

No problem You'll learn, We all learn, different formulas work for different people. I love my super loud obnoxious exhaust the lack of bottom end torque and the car pulls like it has a turbo. Others like to have what ever torque they can pull from a Rotary, But When you get your car runnin the way you want it and it works for you, that is one of the greatest things in the word to me.
