I'm looking for a Kaaz LSD. The MS LSD held fine until the axle went and sent all the torque to the other side in a split second. If your going to trailor your car or dont car about tire wear just make a spool for it. The Quaife LSD I'm not to sure about...I've talked to a few people that say the 10...

The last one was a Mazdaspeed G-series LSD diff in a Pro-LX box...blew the clutch discs apart as a direct result of a custom center axle bar I twisted like a pretzel on both ends,...

lol...you put a T4 turbo on and your power band won't start untill about 4500rpm. A T4 turbo is verrry laggy under that rpm on the 1.6 or 1.8L engines with out using anti-lag, or nitrous. The turbo we used on the BP powered MX-3 is a small Mitsubishi 16G which is one step larger than the Mitsu 14B t...

440's are pushing it on that turbo with only a S-AFC. We had a MX-3 with a BP, small Mitsubishi 16G, S-AFC with Miata RC 440cc injectors, and BP ECU. I belive we ran out of fuel at only 10psi of boost. The reason is your still limited to the stock ECU's injector control range and you won't get an ho...

I'd recommend the Microtech LT8 & LT10 systems for most people and I believe both of them are under $1000 (I know the LT8 is). I'm eyeballing the new Microtech LT16 as it should be available by the time I get the cash ready...that will be a little while...features full closed loop control with 3...

Topic: what rpm's do you shift at
Replies: 52
Views: 13120

I shift at 8000rpm on a stock B6T valve train. To get a engine to rev is more valve train work than anything. You need more cam duration, higher valve spring pressures (most people go to dual valve springs). I'd also recomment titanium retainers, and stronger valves to take the beating. Ferrea makes...

Replies: 3
Views: 620

Fuel Pressure can be a double edge sword. It also depends on what your using for engine management. Remember...as you raise the fuel pressure your injectors will flow more BUT your fuel pump will support less power. As pressure rises, the fuel pump flow decreases. The Wahlbro flow starts to fall off...

Yes the engine can be pulled with out pulling the axles from the hubs...you have to use a cherry picker and pull it out the top. We drop ours out the bottom as the MX-3's struts only have two bolts to remove which will allow the hub assembly to swing out of the way after the axle nut is removed. Wit...

The clutch life depends on several things. Your driving style, torque, clutch material, etc... A metallic clutch can last anywhere from a year (if your next to its torque capacity and slip it all the time on a stock flywheel) to a couple years. The clutch I had started out in a friend of mines car a...
