Rushed and got my '88 10th Anniversary RX-7 back together. We had changed a bunch of things on the car, including adding a standalone, wide band, elec. boost controller, new WG spring, etc etc. All this in a rush to get to our dyno day on Nov. 11.

Quick low-down:

Stock unopened Series5 (GTX) motor
Microtech LT-8s standalone ECU
PLX M-300 Wideband with O2 installed in mid-pipe
Turbo has a 60-1 compressor wheel, P trim turbine wheel, in a T04B front cover with a 0.86 A/R rear housing
HKS T04 undivided manifold
TIAL 35mm WG w/ 12 PSI spring (open dump)
HKS EVC EZ Boost Controller
Custom 3" downpipe/midpipe with Apexi GT Spec catback
100% stock ignition save for the Magnacore plug wires
BUR9EQ spark plugs
FD3S Alternator
Stock fuel lines/rails
720cc x 4 fuel injectors
Walmart 255HP Fuel pump
93 octane pump gas

14 PSI, 17 PSI LOW timing, 17 PSI decent timing

Still only running 7 degrees of advance at max boost We had a brain fart on the dyno in regards to our base timing numbers.

Car pulls 20" of vacuum @ idle and runs great!

Questions/Comments?

That is with the high comp 9.7:1 rotors, correct?
Great results on a stock engine, congrats.
What octane were you using?

 

"Walmart 255HP Fuel pump" Gotta get me one

 

wow glad to hear your car running so well .... i'm veilside from teamfc3s.org.....

would like to know who did your tuning?... and where u bought the turbo from and how much....

sigh im still in the midst of setting up my car etc... such a bummer......

was the microtech install easy?

 

RX: Stock 9.0:1 compression. Fuel was 93 octane pump gas

Carl: :-)

FC: Myself and my buddy Dan (BlackFC on TeamFC3S) did all the tuning ourselves. I bought the car basically as is, except it had a bunch of piggy backs I ripped out and did the car right with the standalone, wideband, etc. etc. MT was simple to install, my car cranked up the first try, and actually drove all the way to the dyno (60 miles) on the stock microtech map.

 

Nice numbers on a 60-1 HiFi(?) considering the timing! Wouldn't you be running out of fuel right at around your power output? It sounds like your 371rwhp run had your injectors flowing damn near 100% duty cycle!

 

Mike you said 0.86 turbine housing... you sure you don't mean 0.96?

 

It's either 0.84 or 0.86. Small little guy. IIRC, I think it's even an divided housing on a non-divided manifold. I am not 100% sure on that. Yes, the turbo is a 60-1 "HI-FI". 3" compressor inlet and 2" compressor outlet.

Yes, I started to max my injectors out, so I raised my static fuel pressure to compensate. The Walbro kept up, and that did the trick.

ah... nice... i do hope u can share your tuning tips with the rest of the group buy members as a lot of us dont know where are we goin....

=(

im goin to use a tech-edge wideband.....

p/s: are u using pre-mix? and did u take pix while installing the microtech ?

 

FC: Yes, the car is running a 100:1 ratio of premix. The Tech Edge wideband works well, especially since it has the NTK sensor that you can mount closer to the turbo. My LSU sensor that I have is working well, but I have it mounted in the midpipe to keep it as far away from the high EGT's of the exhaust. It hasn't given me any issues. There are tons of threads on these forums about tuning. Watch your A/F ratios and don't get crazy with the timing. Rotaries don't need a lot of timing to make good power.

--Mike

 

Nice work, Mike. Get that static pressure raised up to 55psi and then break 400's with it. Add some more advance to the leading and skinny up the trail-split timing to about 8-10 degree split. Nice job!!

Damn i'm Jealous. I have a bigger hotside, and what i feel is a great street port. I'm looking forward to similar numbers. Post some pics with the big thumbs up! You deserve it.

 

BTW: I am putting the car up for sale. $7500 and drive home with 371RWHP, and a 10th Anniversary to boot.

More details to be posted in the Forsale/trade area.

 

What's up with the dyno curves? Why doesn't the torque and HP curve cross at ~5252?

engine pics! nice numbers

 

It does, but the scales on either side of the graph are different.
