I have a 1993 coupe that I bought back in 1995. It was originally built by Lido at Alternative Performance in Michigan and had a Vortech Si-Trim. I ended up blowing the motor due to a faulty ignition retard and bad fuel. I ended up selling the blower to pay for a new motor, because it was my daily driver.
(10yrs later) Today....I received my brand new Vortech V-3 Si Trim supercharger! Everything is still the same set up as before except for the 24lb fuel injectors and GT-40 block. The original set up from Alternative Performance was the Si Trim with a 70mm Mass Air meter calibrated for 24lb injectors, but had 42lb injectors. It ran fine with the blower, but bad with out it. I ended up buying 24lb injectors for running without the blower.
My questions are: 1) What size fuel injectors should I buy, 2) what fuel pressure/timing should I start with, 3) do I need to use the FMU, and 4) does anyone know a place in MI that does tunes for a reasonable price and actually answers the phone?
The original set up didn't have an FMU. I will eventually take it to a shop for a tune, but I was hoping to be able have everything ready to go, which includes injectors. I appreciate any feedback.
My mods are listed below (Bare with me this is from memory and it’s been a while since I've listed everything)
GT-40 block bored .006 over (new)
GT-40 iron cast ported heads
Cobra Upper and GT-40 Lower Ported and polished (port matched)
65mm Throttle body
70mm Mass Air meter calibrated for 24lb injectors
1.6 roller rockers
E303 cam
155lph in tank fuel pump
T-Rex Fuel pump
There are other cooling and suspension upgrades.
