The making of "Evil Spirit"

[rx2mazda]

Thought I would add my build page to this forum.........:D

Okay, I've been wanting to start a thread for my 91 Spirit R/T " EVL SPRT" so here goes.....

I got this car off of this forum almost a year ago and I have had a blast with it. I love "sleepers" and this car is surely one of them. The car was pretty much stock when I bought it except for a 2 1/2 inch straight exhaust, no boost gauge or nada. I added a 3 inch DP w/ electric cut-out, FMIC, WB02, boost gauge, grounding wires, K+N filter, grainger to 15 psi and other small additions. I had a great time beating up on WRX's GTi's and most other cars that came my way. About 3 months ago the turbo gave in and I put her in the garage for the winter. I have really missed my car and it's time to get her back on the road! Since I was replacing the turbo I took off the head and got some TI retainers, new lifters, valve seals, cams seals, arp studs, etc. The car already had a Cometic HG, and Rick D fuel rail. I got a replacement stock turbo (thanks TRYINGBE) but will soon be upgrading to a 50 trim Hybrid, ported exhaust manifold, AFPR, EGT gauge and some other small things. Big thanks to Cindy @ FWDPerformance, I flew out to check out her shop and picked up a few things. She took time out of her hectiic day to show me all her toys and even treated me to some good ol TEXMEX. I recommend her shop to the fullest. Anyway, I plan on big things for my EVLSPRT from looks to performance and this thread will keeps accounts to my Mods. Thanks for checking it out and opinions are welcome

Just got finished powder coating my valve covers and Intake Manifold! Go ahead and bite!! This was not an easy task but I am more than happy with the results. if any ony wants powder coating please contact me thru PM. I can do anything you want in any color, from nuts and bolts to valve covers intakes, etc. What do you think?

I put down 242whp with my stock turbo and computer with a 3-inch DP and cut-out. The dips in torque/hp are KR.

Got 50trim, FWP cal and supporting mods on soon after and put down 368whp. I can't find that DYNO run file so here's the 335whp one I put down before @ 25psi w/alky

"EVL SPRT" was trademarked by our own Fleckster several years back... :D

He even has the license plate!!! :p

I have only been active on this forum for a short time, as evident by my post count. That being said, I did see a post by him with a picture of his car and "EVLSPRT" plates. :mad: And here I was thinking I was the first.

Sorry Fleckster :hail:

[Clay]

hehehe, Fleck is easy going enough.

As for your car, pretty sweet!! any pics of that engine?

[rx2mazda]

On the 368 whp run, what was the torque peak and where was it?

Pat, I can't find the dyno for that run to tell you and I can't remember off hand. It was done back on a Dynapack Dyno. I do know that the HP/TRQ numbers were in close relation. That run was at 30psi with a 75/25 meth water mix. I am going to go to the shop that I did the run at and see if they have it saved under my info. As you can see, my engine starts to lose HP after 6200rpms which is not typical(from the Dynos i've seen)of my set-up which leads me to believe my cam timing is not quiet right. I haven't checked it since I put the head back on awhile ago. As soon as I get my cams centerlined with adj gears, I'm gonna head to the Dyno to see what this holset can do:thumb:

[rx2mazda]

Here's the engine, i little dirty, with the holset.....

Sweet! Nice clean engine bay, a little powder coating goes a long way:thumb: What is the braided line coming off the Fuel rail? Extra injector, gauge? Looks like the rail mounted gage went away when it was added. The top post said you were running some Alky, I can't spot it?

It was a FWP rail mounted gauge. You can see in the top picture that it went away when I put the aftermarket rail on.

How bout' now....

Thanks, R100 is my favorite but they are extremely rare as are the pickups. I sent you a pm Simon :)

Hey, maybe a 13B turbo in a Rampage:thumb: You could satisfy both your urges that way:D

[turboshad]

+1 on the engine and VCs. Things are looking nice and clean. What minimum boost can you run with the Holset WGA?

My MBC is my right foot, full down gets about 27lbs :thumb: I know you have to modify the holset to make it control boost. Shadow has his modified one running 16-17lbs w/ stock Holset WG actuator. I'm being lazy right now

Thanks for the compliments guys/gals.....

what do you rev to?

[rx2mazda]

what do you rev to?

Only 6200 since my dyno shows that power starts dropping after that. As soon as I get my cam timing dialed in I am going back to the dyno.

I have some other gremlins that just reared their heads. Car is making a knocking sound(metal on metal) under light accel at certain engine speeds once the car gets warmed up. Sounded like my dp was hitting the K-frame but I checked and I have 1-1 2/2 inches clearance, with poly mounts I doubt my engine is moving that much under light acceleration. It won't make it at idle or if I rev the motor, only under load. It is not piston slap or anything like that. I suspect one of the following: bad idler or tensioner, bad axle, broken mount or my exhaust is hitting. Hope fully I can get time to check it out soon.

[Ondonti]

or exhaust leak.

[rx2mazda]

Finally got it up on the lift and found the cause....bad axles. About an inch of play in the joint, I think wheel hop did the most damage but the axles are old anyways. Their being replaced now just in time for Cecil, I also got a 58mm TB to install:-)

[rx2mazda]

Looks like some Gremlins are trying to stop me from racing at Cecil next weekend!!!!! Car started running like a$$ last week. Started missing under high boost between about 4.5-5000rpms, I changed the spark plugs and checked all connections and it still did it:( Then Today, after I changed both axles, I started the car and it was running like crap.....check engine light came on. After wiggling the injector wiring harness I found the problem, whenever I moved the connector around the engine started stumbling. Finally I got it in a position where it stops acting up- for now. Also, Speedo starts going crazy around 75mph. Press on the gas and it goes to 150 let off the gas and it comes back to the correct speed.:banghead::confused2:

Pulled codes with my scanner tonight and low and behold:

Code 15 VSS
Code 36 wastegate(i had pulled the sensor so, no suprise here)
Code 27 injector 3 + 4
Code 43 igniton 1 + 2 I

This is pissing me off. I reset all the codes and will see what happens tomorrow. Any ideas/help, shoot away

I would check the connection at the SDS, and it would appear as though you have a problem with your injector harness.

[rx2mazda]

SDS, whats that? I found the problem with the injector wiring harness, are these known to go bad on these cars? Would that cause the ignition fault codes?

[glhs727]

The sds is the speed distance sensor. It sits in the housing off the trans where the intermediate axle slides in. If you were messing with the axles, you may have damaged it or disconnected. Likely where the code 15 came from and could contribute to some funky running.
later,
Cindy

[Tony Hanna]

SDS=speed/distance sensor, aka vehicle speed sensor. Often the connector on the sensor will get oily and cause an intermittent connection. They can usually benefit from a good cleaning of the sensor and wiring harness connectors with some brake cleaner.

Was the injector harness problem at a connector? If so, disconnect it and look for green crap on the terminals. Clean, apply bulb grease, and reconnect. That should put a stop to it (it's worked for me in the past).

edit: Cindy beat me to it.:)

[rx2mazda]

Thanks, I was sitting here trying to figure out what SDS was but I couldn't, i'm usually good with my accros......maybe it has something to do with the beers in my hands, this car leads me to drink:) Sensor is new but it is very oily, I will clean/lube it tomorrow(no Pun please, lol)

Seemed to be at the connector, I will also give that the treatment tomorrow. According to ALLPAR code 43 can be caused by:

# 43 Peak primary coil current not achieved with max dwell time
OR
# 43 Cylinder misfire
OR
# 43 Problem in power module to logic module interface

So, if the injector harness problem caused the misfire, it could have caused the code 43 and not an actual problem with the ignition circuit? Hope thats it.

EDIT: injector code was for cylinders 3,4 and ignition was for 1,2:(

[Tony Hanna]

Hmm, I don't know much about a code 43, but if it's applicable for a misfire, the injector wiring could definitely be causing that.

I'm calling to bug you tomorrow:D

[rx2mazda]

Well, I might not make it because of these problems :( Got the speedo connector cleaned and lubed and that fixed the speedo problem. I also cleaned and lubed the injector harness and coil but the car is still breaking up when it gets into boost. Runs fine otherwise. I noticed that once the boost starts coming up, the mixture gets lean. I have a hunch that my Alky controller is interfering with the map signal. Hopefully, I will get time before saturday to pull out my multimeter and start going over stupid values:mad: Any suggestions are welcome.:thumb:

Are you able to pull the alky controller out of the map vacuum line and not boost too high? I'm assuming that you have the controller in the map line.

[rx2mazda]

Yes, the controller is hooked into the map line with a quick connect so I can remove it easily. Problem is, I have no boost controller so i get full boost when I mash it. I can either disconnect it and pop in some 110 race gas that I have and see if that fixes it or hook up pressure to my map lines with the key on and take voltage readings.

EDIT: it reads map voltage, not from the vacuum line

just pressurize the system or just the line to the map, then read the voltage with a DMM

Hmm... A lean-out can cause a misfire, but it can also be caused by a misfire (as far as an O2 sensor is concerned). A gauge will show lean as a result of all the extra O2 from the unburned fuel/air mix being pumped into the exhaust by the misfiring cylinder. To add to the confusion, you can also get a pretty serious misfire from running too much alky (blubbers like an over-rich two stroke). I think you're on the right track with the pressure vs. voltage readings from the map but I'd also recommend reading the plugs so that you can get an accurate idea of what's going on in the engine when the misfire happens.

Also, what's going on with your EGT's at the time leading up to and during the misfire? If the EGT's climb up to the point that it starts to break up, then I'd say it's a legitimate lean-out. If the EGT's are dropping up to the point that the misfire occurs, then it may be a case of putting out the spark due to too much fuel and/or alky. Again, reading the plugs should give a good indication one way or the other.

I was into a similar situation with my old Daytona (the car in my sig pic). I was running stock electronics with a cutout raiser and a home made single stage alky injection rig with a huge nozzle (on or off, no progressive controller). It was enough to support 28 psi on pure methanol with a stock fuel system but it had a flaw. If the boost didn't come up quick enough once the alky kicked on, it would break up like crazy and show lean on the A/F gauge. I'm not saying that is your problem, but it might be worth looking into.

[turboshad]

You said you changed the plugs. Are they gapped the same as the old ones?

Check that map voltage...it does sound like the map signal is being corrupted. If that's the case, load it up with 110 and let her rip on Saturday.

Hey Guys, i'm looking for a GOOD injector harness. If anyone has one please let me know, Thanks. Has anyone had success rewiring one? I don't know if I have time to do that.

[1qk4dr]

Nice Project! I hope someday I'll be able to get my car looking as clean as yours.

BTW how do you have your Air Filter routed?

Ditto, before I bought my DD kit, I had a homemade one and when it came on, it would fart and sputter so I had to be ready for it.

Rewiring isn't hard, I had to do that to my 8 valve harness when I put the TIII in. I used a Quad 4 harness as I like the injector connectors better and the wire was alot newer. Took about an hour to measure, cut a and splice, :thumb:
