I got the 6PI working again in my '90 GXL. While I had the LIM off, I installed the Pineapple Racing 6-port sleeve inserts. The engine is stock and I still run the factory; fan, p/s, a/c and air pump. I have installed a professional racing shop custom fabricated CAI off a friend's parted out SCCA Pro Solo II car. The exhaust consists of a CorkSport header with a Catco main cat and a Borla cat back system.

I had her on a Mustang dyno this morning and she made;

146 rwHP @ 7100 RPM with 111 ft-lbs of torque @ 6250 RPM

Remember that numbers off a Mustang dyno are about 13% lower than a DynoJet, so that would work out to about:

165 rwHP and 125 ft-lbs of torque

I have not yet installed the Rtek 2.0 with the wide band O2, so there maybe something left in the tune. Other than a bit too raspy and noisy exhaust note, I am very happy with the results.

 

Nice. How many miles on the engine?

From what I've read you'll probably see the most gains from that rtek + tuning - do post the results!

 

Thanks.

The engine is a blue tag Mazda rebuilt. The PO had it installed at the dealership in Aug 2000. I have all the paperwork. It has 31K miles on it since then.

 

That's a very decent amount of power..even the 146 is pretty impressive

 

Very impressive for an NA.

 

Very good! My red car has: S4 intake [hot air intake - cone filter unboxed], Pineapple sleeve inserts, S5 rotors, S4 plates [stock ports], FD housings, RB header/presilencer/catback, and made 157RWHP on a dynojet, ~165K mi on the plates, ~81K on the housings and ~4K on atkins apex seals during the test.

*for comparison.

Tune should help, as well as removing the cat.... But I'd never do that on a street car...

 

Once I clean my aux ports, get sleeves I would love to make those kind of numbers. I'm still on the stock/original block with 60k miles.

 

sooo like, did you get the car out of a time capsule?

i bet everything works all good and **** hahaha.. my chassis has about 199994 on it, and its pretty rough

 

Interior looks mint too. I have a massive pull/surge at 5500rpm. Similar to a vtec feeling I got in my Civic. I made a thread about it and people told me to check my aux ports and I can only move one of them, the other is stuck. Once I free those up, I should gain a lot more power down low. My car feels old though, which is odd. I want to replace all the bushings, get coilovers, replace brakes. I feel like the car will feel more alive once I replace all the old/original stuff. The car was only driven something like 2,000kms in 3 years, so everythings aged.

 

cool

 

i think the "surge" is just the feeling every rx7 owner gets when up in the rpm's.. that's just where our power is.. i love it too

 

I know, but right at 5500 it's a whole new level. Most people say it shouldn't be that noticeable.

 

Ryan2949>> You have an S5.. It was always VERY noticeable on my S5 'vert. I wouldn't worry about it.

 

In a n/a S5 the Variable Dynamic Intake (VDI) is triggered at 5312 RPM - that is what you are feeling.

 

 

Sweet numbers! How hard was it to put this sleeves in? I bet if you got an E-Fan, took off the AC and underdrive alternator pulley you would put down close to 175 at the wheel.

I wonder what I'm putting down, I'm all stock with an autoparts store custom intake and a straight pipe from the manifold to a cherry bomb...

 

Thanks. I had to take the intake apart anyways due to the 6 port sleeves being carbon locked. For me personally it was not too difficult, but have had a lot of project cars over the years - although this is the first RX7 that I have wrenched on.

I now have the E-fan hooked up;

But I will be keeping the A/C and PS.

The big thing would be to finally install the Rtek7 2.0 and the WB O2 and get the maps dialed in better.
