MPi vs SPi

[jellison]

Told by Wood and Pickett that all 96 onwards are MPI is this right?

Saw a Paul Smith one 98 saying it is SPi.

Anyone have anything diffinitive on this and presume MPi's make more power than SPi (any offical numbers?) and are better to tune.

Dunno about MPi or SPi.....

HIF44, Torquemaster, Maniflow and RC40 is my chosen recipe for a quick road car.

Done all that (even twin 1.75's!) - fine for a while but a drag with a 3.44 diff after a while.

MPI from yesterday at the LSMOC track days seems the way to go and emeral if blowing it.

If you do insist on running injection, use a 7 port head. The science is pretty straightforward, it doesn't like it. If you were going to run emerald silly ignition, you may as well buy a 7 port head and run megasquirt/jolt, programmable everything for a fraction of the cost. I believe that the manifolds are good for mounting superchargers on though. Then go and bung the HIF44 somewhere else!

John,

I'd buy the wife a Punto Then the noise then isn't an issue.

And then take that offer up on the 1380 to go with your loony carbs.

Had a go in Suart Wrights Turbo Beast and another chaps 160bhp Vmax SC one - I want the Vmax one.

Do it in stages - my a late quite MPI Sport pack and start modding all over again!
