The vehicle chosen is a 92 Mazda MX-3 GS 24-valve V6 and manual transmission. However that power plant was removed in favor of a more potent 1.8 BP-DE from a 94’ Miata. The drive train chosen is a protégé lx transmission.
The swap was quite simple as sourcing parts from local junkyards were plentiful. All that was need was the 4cly cross member,radiater, shift linkage, and passenger side motor mount bracket. The oil pan was replaced with that of the fwd BP oil pan as well as the water pump. The V6 passenger motor mount was simply unbolted and the 4 cyl bolted in place. No cutting, welding, or any other fabrication. The reason is about a ½’’ gap.
The axles for a protégé LX transmission were used. The splines fitted correctly on the original hub assembly. So that made things much easier as nothing had to be removed and swapped out.
After everything was in place and ensured that fitment was correct and proved to be a direct bolt up, the power plant was ready to be worked on. A RacingMazda custom intake manifold, tubular exhaust manifold, Electromotive TEC 3 standalone, (upgraded) T4 67 p-trim ball bearing turbo, 2.5 in intercooler piping, 31”x 12” x 3.5” front mount intercooler, RC 1000cc injectors,adjustable Cam gears, RacingMazda fuel rail, 255 walbro fuel pump, Aero Motive FPR, Innovate Wideband O2 sensor, Tial BOV, Greddy electronic boost controller, and Tial 38 mm waste gate, and custom 3“ 1 ½ dump pipe. (Upgraded) Quater Master Twin disc clutch & Fidenza flywheel. (Upgraded BP) RacingMazda X-Block converted to a 2.0, X-head port/potish, ferra values & springs, tit. retainer, custom camshaft with a 406 lift, soild lifter shim underbuckets setup. Good for 10,500 rpms!!
(Update) we decided to go all out and junk the stock BP for a all out race setup MX-3 will be dynoed and tracked test within 2 weeks from now 4-19-06
This past Saturday, April 8, the mx3 was slightly tuned and it was taken to River City Speedway and ran a best time of 12.7@106 at 8psi with slicks & race fuel. There were some issues with the boost controller as it wouldn’t go past 8psi.
Time slips and pictures of the project outcast MX-3 will be posted soon.
