DIV 1 rally/track 4AGE(objective +- 130 whp)

this seems to be more or less spot on from what you desire with not much extra parts
for reference his CR is probably around 10.8:1 +/-0.2

from another forum Wrote:

This was my first-ever complete engine rebuild. I had the machine work done, but I did the complete assembly myself, except for the pistons onto the rods (I was going to , but they did it for me, probably due to the balancing.)

[list]
[*]7-rib block
[*]OEM 0.5mm (first oversize) 10.3:1 pistons (from GM dealer for the Prism GSI).
[*]TRD 0.8mm head gasket (should've gone with a 0.6mm!)
[*]new Supertech valves (standard size)
[*]bronze valve guides
[*]smoothed intake/polished exhaust ports (I just cleaned up the casting flash and ugly bumps)
[*]Illegal Garage flywheel/clutch (lightweight!)
[*]OEM ECU
[*]no-name cone filter
[*]home-built exhaust welded from 2" mandrel bends.
[/list:u]

Fast-forward another year or so:



What changed?
I talked to Bob, and he gave me some GREAT advice!!
So, this is what I ended up doing:

[list]
[*]4-1 header (BBP, modified to not rub the steering rack or the floor.)
[*]SARD adjustable fuel pressure regulator.
[*]TODA cams. 264 intake, 256 exhaust.
[*]NST adjustable cam gears.
[*]had a buddy lathe up some new knock pins for the cams. the NST gears have a hole that is too big, and could allow a theoretical 2° or more difference in cam timing.
[*]when I did the valve shims, Every single one of each bank (intake or exhaust) was identical, at the minimum spec. no "it's in the range, close enough for me."
[*]electric fan
[*]installed power steering.
[/list:u]

first pull at the dyno was 130.4. twelve runs later, and the cams were exactly where TODA said to put them. I advanced ignition timing by 4°, and added 2psi of fuel to get the 133.0.
