If the vrx astra uses a similair chassis to the vectra it wont come even close

Madza engines havent been known for their build qualify in the past, good to see they have put a bit of effort in this time around. The 6 MPS was reviewed in the latest episode of top gear against the new ford mondeo 220hp and the vectra 4 door turbo. Jeremy Clarkson thought the MPS was the best to drive but would buy the Mondeo if he had the choice. In the straight line drag the Vectra was fastest, followed closly by the MPS and then the Mondeo.

The turbo on the MPS will be a similiar size to a Garrett GT28. Anything more than 1 bar (14.5psi) and it will be out of its efficiency range, so creating more heat than useful air to create power. And as for boost spikes in the winter, that would be BS as boost spikes only occur when you install a manual bleed valve style boost controller. The MPS will be running an electronic boost comtroller connected to the main ecu. And as for the engine handling 30psi, unless its running forged pistons and rods special valves it may last a few runs at 30psi with a bigger turbo before it starts to melt the pistons and throw a rod.

sorry mate, i cant help but to think u are a bit of a showoff :) Nope, just saying I know abit about turbos and other related issues with turbochraged cars ;)

All new car's try to take away the fun when you start modifying them. But there will always be a company that comes up with a piggyback ecu to over ride this. Even the LS1 ecu's retart the timing etc when you start to modify them, but LS1Edit took care of that problem.

Turbos must be new to you guys?? My gfriend has a 05 3 SP23 and we are going to go test drive the MP3 on the weekend and look at upgrading. My cars are a 325kw@wheels skyline and Lexus LS400.

Hows the road noise? The normal 3 has a heap of road noise

Atleast Mazda has addressed the bad torque steer fwd turbo cars have, unlike the astra turbo

The mazda rx8 has always been slow. Theres a supercharger kit available for it now from a few workshops in aus

Hey people I am after the ecu wiring diagram for the 1990 celsior so I can wire in an apexi safc. I am also after the wiring digram so I can send to person interested in buying my tow bar so they can wire in the appropriate brake and indicator lights to their trailer.
