Hi guys,
Wondering if anybody has ever tried to make some decent power out of these little motors?
I'm about to start building a 3L (2.8 litre 4 Cyl. IDI) for performance. Target is 300 rear wheel hp on diesel/LPG. Going to get it to spin to 6k rpm to make the power without bending rods! I'll list the mods I'm thinking for this build below, any advice or ideas are welcome and appreciated.
Custom I beam rods
Coated pistons
Thinking of cryo treating the crank, cam and rods
Bored .030 over
Fire rings
Girdle plate
45-60 PSI compound or VGT setup
Rotating assembly lightened and balanced to 7k rpm for head room above my expected redline.
Custom pump
Custom plenum/manifold
Water to air intercooler
I'm already running a fairly worked head on my current bottom end; ported and gasket matched, valve seats cut to the edge of the valve and raised 1mm into the head, throat cut and a reground cam for lifter clearance and better duration. I'll be dropping a set of precombustion chambers and stiffer or dual row valve springs in.
LPG usually accounts for 25% of the overall power, so straight diesel hp needs to be around the 225 mark at the rear wheels. Anybody seen something like this done? Even on a similar motor?
