Alright so i finally finished up my built...motor ended up making 216.78WHP. Im happy with it..but i was wondering if there is anything else i could do to make it gain more power. NOTHING INTERNAL..as far as we would go is maybe chaging the cams..but no pistons or anything like that. here is the specs of the motor build.

The motor compression was said to be around 12:0 to 12:1 compression. I was looking to maybe changing the Skunk2 PRO to Edelbrock Performance X manifold. Also wat other cams out there can i run on the street that will outperforme the skunk2 stage 3 tuners. Remember i have Tuners series valve train, so i guess that leaves PRO series cams out.

 

Do the IM change to the Performer X. When you’re changing the IM get new injectors FIC525's. They have an improved spray pattern that improves atomization. This equals more power. Is the 3” intake piping a CAI? If not you may want to change that as well.

If you change the IM would you be selling your old one? I am running a Performer X now and would like to conduct a test on my engine with a Skunk2 Pro.

 

bigger cams, nitro methane, moar compression

 

you can run pro1 cams with the tuner series vt.

 

Turbo. SC.. Bigger engine!

 

ya im thinkin about changing the IM....wat cams would you suggest i should try? im looking for atleast 225-230whp im at 216whp right now. i can upgrade the IM to Performance X, Upgrade the cams to something better then stage 3 tuners, and upgrade my short ram intake to a CAI with the Velocity stack in the front of the car.


what do you guys think power gains would be?

 

3in exhaust, cold air and the manifold. should be enough to hit your goal

 

best advice right here. you've already pretty much maxed out your setup with the mods you have. may i ask why you wouldn't want to at least port the head?

 

+1 on porting, its not like the GSR is the best flowing head so theres plenty to improve on there.

 

Very little with an IM change from SKunk to Performer X. The CAI will give more peak power but less midrange. You really want to ask yourself what it is you want out of the car beside the typical American answer of MORE POWER. if that's simply the case, time to turbocharge the engine or buy a Pushrod V8 and call it a wrap. Otherwise, this discussion gets rather cynical

 

I didnt really built this motor to be a race car or be the fastest....only reason why im asking what i would do to improve my HP (my goal would be 230whp) is because i know the car has potential. Ive seen 82mm GSR motor do 230...so why cant i make 230 on a 85mm b20? thats where im getting at...
