its hard to say which one will be faster, they truly drive like 2 different cars.
One raw and in your face, the other smooth and subdued.
I think the dyno will be in the turbo car's favor.
The other has the weight and torque advantage- tough call. LT1 car dynoed 326hp/360tq corrected btw.
I was putting the car away and when it was sitting sideways at my gate I should have taken a picture, it looked nice with a clear side shot.
Instead I pulled it in the driveway and took these, did not get the same effect- night pictures suck!
FTP lenses are not in becuase I have to take the bumper back off to paint it and change the lip.
Rims and tires are definitly needed, I have been on the prowl for a year trying to find something I like, and going
back and forth between 17's and 18's.

What a nice build. I really like your UIM/LIM paint job. You have that whole black/grey theme through out the whole car, looks great.
If I read correctly, you're running custom piping to dual RB cans? No pre-silencer right? Either way, maybe when you're boosting i'd love to see a vid clip of it in action.

a member here used to make those pedals, he stopped along time ago- those were actually the very last set he had.
They call them "sleddriver" pedals.
I remember seeing another company that makes ones that look pretty much exactly like them, but the name is not coming to me right now.
revvin- I have a fiberglass and a aluminum piece to go on the radiator support- im waiting to paint the bumper before I install it.
Im also going to tie the undertray into the lip, clearing the air to the tray decreased my temps by 20 degrees on the highway.

if you factor in the rear end rebuild, trans rebuild, FD rotating assembly, new oil pump, stationary gears, porting, etc and so forth
I would used alot of new parts where I could, every thing else was rebuilt, so figuring all that probably in the $12k-$15k range

this is going to be long, it is my summery of my swap.
well we changed a few things in the engine compartment, by now im sure most of you have seen plenty of pictures of my engine bay floating around.
We got the ribbed pulley swap finished, in the end I ended up with 2 rotor cosmo main and water pump pulleys, a FD alternator pulley, I used a non-ps bracket from a TII which was modified so that it could line up with the main pulleys. On that is a FD AC compressor and a FD tensioner. Now all I have to do is have AC lines made, but I have all winter for that.
The mechanical OMP is in operation, we swapped out the S5 throttle body for a S4 one and using a rotary aviation adaptor I pump 2 stroke oil through the OMP lines, it works off mechanical linkage just as a S4 TII does. The main difference with using my set up and the OMP system is that the car now BURNS 2 STROKE oil, it no longer just pumps some motor oil, it now pumps 2 stroke oil that is meant to be burned. We get heavy traffic here sometimes, I did not want to sit in traffic with 2 stroke pumping out the exaust through the open roof.
I swapped out the HKS boost controller for a new Greddy profec-b- spec 2. Its a little complicated to set up because it does more then high boost and low boost, it allows you to adjust feed back, when to start the boost, and some other stuff which honestly I dont know much about yet as I just got back from test driving the car.
So now onto the car- it drives like it came from the factory. It idles, runs, steers, and operates as if it was a factory car. Its not too loud or annoying to drive at all. I swapped out the tired stock suspension for Racing Beat springs and KYB AGX adjustable shocks with new mounts. I have Tein coil overs in my other FC and I hate the ride.
I sent the car out for its alignment and everything is perfect. I did order new rear steer eliminator bushings and mazdatrix adjustable rear camber links as well to get the rear up to snuff.
So far I have only put a few hundred miles on the car because it seems like I am always changing something and only get to drive it a little on the weekends.
We dyno tuned the car to a VERY safe and conservative tune at 14lbs. We did initally have it up to about 18 lbs but I am not running that boost and did not get power pull numbers from 18lbs. I am now going to install my coolingmist kit so I can safely run 18lbs of boost- but I KNOW a turbo change is in order. I did not build the car to run this small turbo and now that the car is sorted out its larger turbo time with a GT35R as my current choice. I dont want the car to be a dyno queen and I know there are plenty of faster cars out there. I just want the car to run and drive responsive on the street.
The "3630cfm" electric fan cools the car right down and on the highway if I cruise along at 70mph nice and easy the car runs right at 180-185 with no fan on.
The alternator is keeping the voltage at 14volts+ sitting at a stop light with the headlights, electric fan, and stereo w/amp on.
Here are yet more pictures of the engine bay showing the pulleys and one over-all shot. I still have to put my mazdatrix strut bar on, I just had it sitting there to see if I liked the color or not.
Winter plans are body updates, I know I have to paint the front bumper, I have all S5 conversion parts for the car as well.

The car had 2 paint jobs in 2 years. The first paint job was the major one. I painted it myself, at the time I drove the car daily so I painted it when we closed up shop over christmas break.
I used to stop driving the car in the winter and put my jeep on the road instead, At the time I could not afford insurance on both vehicles so I drove the jeep over the winter which I also plowed snow with, come spring time I would take the jeep off the road and put the RX7 back.
What I did that year was take the car off the road in september and do all the bodywork and prime the car with DuPont URO primer.
The car then sat until december which allowed the bodywork to tighten up by heating and cooling off. I then block sanded the car and re-primed it.
I block sanded the car again and washed it, moved it into the shop blew it off and let it sit overnight to dry out some more.
Next day masked it and sprayed it with single stage black DuPont Imron that I slightly tinted to make it appear more black. At the time I used a DeVilbiss GTi HVLP gun and I had a prototype Millenium 2000 cap that DeVilbiss had given me to try which later became standard on the Gti gun, 65psi at the wall, 30 psi into the gun, 10 psi at the cap- pretty standard stuff.
I let the car sit a day then wetsanded and polished the car.
Driving the car everyday for the next 2 years a few things happened- one is I wanted to spray all the moldings, mirrors and trim which I had originally left unpainted. 2 other events happened- a guy at work backed into the door so I needed to re-paint that. I had also gone to dinner one night and the valet parker hit the OTHER side of the car into something and put a scratch down the side so I had to paint the fender and door on THAT side. Being the car was already painted I decided instead of just shooting 2 fenders, a door, and a bunch of trim why not just sand the car and re-shoot it all? MUCH easier the second time!
this is a picture I took with a 35mm camera, digital cameras were not easy to come by at the time- at least not on my budget. I rolled the car outside to take this picture after I was done with the paintjob. I have a bunch of print pictures somewhere of the whole job.

Had the car dyno tuned by Wayne aka Waynespeed, he is the dist. for Wolf computers and has many reliable high powered tunes to his credit.
We tuned it back on the 9th, but I just got the print out last night. Last night driving to get the printout I realized for the first time my factory tach falls off at higher RPM, I know at about 4200 on the tach the wolf was reading about 400-500 rpm LOWER.
Picking up the dyno sheets confirmed what I thought- originally we revved the car to what we thought was 7200RPM, turns out it was only 6150 RPM!
My rear alighment is way off right now and we are re-doing my pipes from the REV II y-pipe back to 2.5" from 2.25" so when thats done its back to the dyno to confirm the tune is clean to a real 7200RPM and with the exaust changes and the alighment not acting against the dyno.
Here are the 2 graphs, one does not show torque or RPM just peak HP but thats the 4th gear pull.
The 4th gear pull is the blue line, showing a peak of 280hp at what was 6153RPM. Not bad considering the small turbo and the fact we had 1000 rpm to go.
Motor is a street port S5TII turbo is a garrett t04b. A turbo change is already running through my head, I just wanted to get the swap done and sorted out first.
The second graph is a 5th gear pull so I guess that one wont count but it does show the engine RPM.
Some picts of getting it on the dyno and the graphs

went back to the dyno tonight to tune the Wolf V500.
Wayne from Waynespeed worked his magic and played with the setting and we utilized the built in boost controller and even a shift light output from the Wolf. The wolf offers so much most people, including myself, do not realize what it can do when the right person is tuning it.
Big thanks to Roan, Steve, Marley, and anyone else im leaving out.
Im happy with the magic number of 400hp and about 285 ft lbs torque.
I have more graphs but I have to scan them, and its late and I need to go to sleep!
Im going to cross post this to my previous dyno thread and my other project thread.
if anyone cares enough check out my "winter projects" thread for many updates on my vert

Wow.. No questions from me, I just want to say that you and everyone else who worked on the car did an amazing job. Very tasteful, very clean, and hopefully very fun for you to drive!
