Default 2004 usdm sti cams in a 2L

ok so my setup is as follows.

wrx block
crank
rods
heads
V6 sti pistons
vf30
sti pinks
v7 intercooler
ecutek
v7 intake rail
255lph fuel pump.

right now i have the stock cams and last time i was on the dyno my powercurve falls off sharply after 6600rpm, would changing to the usdm sti cams give me a better powercurve, i dont wan to lose lowend but more top end would be nice! with the avcs delete mods obviously on the cams.

experts and mod motor nuts chime in please. thanks

John

Default torque curve

more than likely you will lose some low end and move your power higher in the rpm scale. do you plan on driving more at 6600 or 3500?

search FIRST, then PM!!!

Default

they are a good "cheap" upgrade and would deliver a good all around cam for 2.0L...
IIRC they are suppose to be 256/256 with 9.6 mm and 9.8 mm lift on intake and exhaust respectively...
stock ej205's are 256's as well but 9.27/9.17 for lifts...so less top end oriented on the lift specs and a noticable amount less overall lift.

so a good little upgrade...but you will need to have the avcs oiling ports plugged, which is very simple for a machine shop.


you've now reminded me that I need to sell mine...thanks
