well due to worn piston rings its time to rebuild my motor... just looking for some opinons from u guys on what kind of hp this setup will put down :

my daily driver: 00 blk gsr 3 door 141,000+ miles mods:
aem cold air , dc 4-1 , hi-flow cat and lightweight fly

after rebuild adding:
ITR pistons 81.5mm, bc spec3+ cams, cam gears, blox springs/retainers, undox. crank pulley

when i bought the car a lil over 4 yrs ago the only problem i had was it was running rich(killed my oem cat.) and it took me forever to figure out what was going on. come to find out it was running a ITR ecu , i quickly swaped it 4 a gsr ecu. well now after the rebuild im going to put the ITR ecu back in, hope to take advantage of higher redline.

im hoping for 175whp or more .... what u guys think? ITR ecu good enough to run this?


plan on going to Inlinefour for dyno testing after its done.

 

Where did you find 81.5mm ITR pistons?
What intake are you running? GSR or a single runner.
DO NOT use the undox. crank pulley. Do some homework on this and you'll know why.
I would get a programable ECU with Crome Pro, Hondata, Neptune to get the most out of your engine.
I was able to make 175whp with GSR cams so if you do get it tuned with the BC3+ you should be able to get more than the 175whp.

 

- the 81.5mm ITR pistons i got from :www.inlinefour.com
im also getting there 82mm bore head gasket
-running the gsr intake manifold
- as for the crank pulley its something ive had in the closet setting there for like 5 yrs just wanted to get some use out of it. Well what are the drawbacks of using the undox. crank pulley?
-idk dont feel like spending the money on obd 1 conversion or a piggy back. the ITR ecu has the higher redline, just going to stick with the itr fuel maps

 

stick to the oem crank pulley and sell the undox to somebody. they don't have anything built in them to take shock and vibration created by the crank

 

Bad idea. The ITR map is only good for a B18C5 with stock breather mods. If you're making any changes you need to get a proper tune. Besides that, even with a mild all motor build a proper tune will give more power for the money than any other mod you can do.
