1994 Mazda RX-7
Up for auction is my latest build a 1994 Mazda RX7 with a turbocharged LS based drive train. The car has been on the road in it's current form for about 60 days now and has 2000 plus shakedown miles on it. Overall it's a great driver that will sit in Los Angeles traffic without a hiccup. It is also easily the quickest and fastest car I have ever built or driven. This thing requires all your attention under boost both hands on the wheel and remember to breathe.I started with a sort of half finished project I purchased off an RX7 swap forum. The guy I bought it from spent six years on the project and spared no expense when it came to buying parts. Unfortunately it still required a ton of work when I got it the more I looked the more issues I found. When I realized the motor had to come back out I went a little crazy and ended up with this monster.The motor is an LS2 from an early 2005 GTO. This means it is an aluminum block 6.0 with the 24x reluctor wheel (uses a drive by cable throttle body and 0411 PCM) To this I added a set of GMPP/Katech ported LS3 heads these flow 360 CFM. I also added an LS9 camshaft ARP head bolts MLS head gaskets and good valve springs (130 on the seat 330 open). I also opened the ring gaps to .023 for boost. The previous owner claimed this motor had 5000-ish miles on it and after opening it up I agree. There's no varnish anywhere. Pistons rods and crank are stock and this motor came with the much better Gen 4 rods. It has a factory LS7 clutch setup as well and the T56 6 speed is also from a GTO. The transmission is stock with the exception of a Steeda Tri Ax shifter. I used a stock LS3 intake manifold with a 90mm Edelbrock throttle body. The fuel system starts with a CJ Motorsports hanger in the tank running dual Bosch 044 fuel pumps there's a -8 feed to the Holley fuel rails. I used 80 pound Seimens Deka injectors and an Aermotive fuel pressure regulator that returns to the tank with a -6 line. Engine management is handled using the stock 0411 PCM but I changed to an LS3/LS7 slot style MAF and the LS3 MAP. I also tucked the engine wiring harness when it all went back together.The turbo setup is all custom made in house it's centered around a Borg Warner Airwerks series S471. This turbo feartures a 71mm compresor and an 84mm turbine it has a T4 flange with a true twin scroll exhaust housing. I used C6 Corvette manifolds heavily modified for this application and the up pipes are 2" to help spool. There's a pair of 38mm Tial MV-S waste gates to control boost and a matching 50mm Tial blow off valve. The downpipe is 4" out of the turbo and reduces to 3.5" almost immediately. The 3.5" runs almost all the way back and necks down again to meet the aftermarket 3" exhaust that came with the car. There's an air to air intercooler and the entire charge side is done in aluminum.The stock rear differential was replaced with an 8.8 center section from a 2003 Cobra it has new 3.27 gears and a new posi unit. It's held in place with a cradle from Samberg and there's custom CV axles from the Drive Shaft Shop. The driveshaft is also a DSS item and very nicely made as well. I added K Sport coil overs and a set of Enkei NT03 wheels (18 x 9 &18 x 11). The rear tires are Nitto NT05's and the fronts are Goodyear Eagles. I also added a set of Wilwood front brakes these are the floating 13" rotors with six piston billet calipers. I removed the stock ABS system and there's a Mazda 929 master cylinder as well. The rest of the suspension is all new with derelin bushings everywhere gigantic sway bars front and rear with adjustable end links it also has adjustable rear links from Improved Racing.The rest of the car is pretty nice it's a non-sunroof model (R1? Not sure...). I had my guys do a quicky paint job on it a few months back it's shot in two stage but the paint has shrunk up a bit and it could use another color sand & buff. There's a few very minor chips here and there and there's a dent in the hood where the previous owner shut the hood on the throttle body.The seats are suede R1 seats the steering wheel is from Momo. The dash is very nice and uncut I did install some Autometer gauges (mechanical water temp vacuum/boost and analog AFR). I made my own pod mount that fits in the stock middle speaker opening which could easily be removed or changed I did not modify the actual dash and I do have a new from Mazda speaker grill. The interior is missing the kick panels the upper steering column cover and the tool box & jack covers in the rear. The stock speedometer is not hooked up but I do have the Dakota Digital adapter box that will go with the car. The stock temp gauge does not work but all the others do although the oil pressure gauge is not accurate. There is power steering but no A/C I did not hook up the heater box but everything is there and all it needs is a couple fittings and some hose. The horn does not work. The rear wiper does not work but I don't think that hatch is original to this car. Everything else works and this car has been my daily driver for the last couple of months.Over all the car is well sorted and crazy fast. On the dyno I saw 500-ish at the tire on 10 pounds of boost at about 4800 rpm but I had an issue with spark blowout. I fixed that and now it pulls to the limiter (6300) but I have not taken it back to the dyno to verify power. My local track will not let me run the car without a roll bar so I can't offer any timeslips. My butt dyno says it's an easy 9 second car it will spin the tire hard from a roll in second gear and wag the tail pretty good in third. It does hook at the top of third gear and it pulls very very hard. It weighs 2800-ish with me in it and is making at least 650 at the tire. There is virtually no turbo lag it starts making actual boost at 2000 rpm and is on the wastegate spring by 3500. The heads/cam combo comes on at 3900 rpm so when it hits it hits hard.This is a great opportunity to buy a well sorted swapped RX7. I own and operate a full service hot rod and restoration shop this car is built with the attention to detail that we give all our client cars. It still needs some finishing touches and there's always room to make even more power with a set of good rods and pistons.
