We're going to get the turbo 'up & running' on the stock
NA engine to work out the piping, intercooler location, BOV location, etc.
I figure she's good for around 8 psi on the stock engine with a J&S
knock sensor (I'm guessing this is good for 185 rwhp). I've got a local
guy who built a turbo manifold, and has agreed to fabricate much of the
piping. The final tuning will be done by GReddy, Tod (thanks, Tod!), and
myself.
The 'real' engine will be a ZE block Benson's Machine is building with
JE Pistons, Crower Rods, GReddy head gasket, ARP studs & bolts, etc.
TRD USA is building the cylinder head (big port w/ T-VIS) with stock cams
(generally speaking, less overlap is better for turbos), and the car already
has a limited-slip & McLeod clutch. Estimated power: greater than 300
rwhp @ 20 psi.
Sure, there are bigger turbos out there, but our objective is to build
a very quick & reliable street car, capable of low 12 second 1/4 mile
runs with an ultra-responsive turbo. the neatest thing about this new prototype
T28 is the compressor blades, which are completely cut from a forged blank
with a 5-Axis CNC mill- MUCH more precise than a cast part.
The electronics were all sponsored by GReddy, and a fair amount of the
parts & machining costs are being done at a reduced cost- thankfully,
I work 'in the business,' and the car is slated for coverage in Turbo mag
& Sport Compact Car mag. Look for the car to start 'showing up' in
early 2002. I'll keep you all posted with dyno printouts as work progresses.
