k20z3 all motor build

[ainokea_si]

Hey guys,

I have a 07 Civic Si and going for a all motor build. I was planning on using nothing but Brian Crower parts. My car currently has bolt ons (cai, dcrh, apexi ws2). I am first going with the NST tuning pulleys, pr2 spacer, and hondata flash with gasket.

The first portion of the build will be stage 2 cams with springs and retainers. Next, I will sell those cams and get the stage 3 cams with BC rods. The pistons I do not know who to go with but I know that I want at least 12:5.1 or 13:1 because my car currently has 11:1. If you guys know of any pistons that I should go with that work well with BC let me know?

I will post Dynos after each install portions. Currently I have 202whp and 157 tq.

What do you guys think or what else do you think that I am missing? What type of power output do you think that I will achieve?

Thanks for you guys help! I like this site much better than the 8thcivic site because of the knowledge base that is on this site. Thanks again for your help!

that is the part that really sucks! our car does not have a engine management! no hondata kpro. our car has a drive by wire and is managed by the ecu air flow!

the only thing that is offered is AEM Fuel and Ignition Controller which i will eventually have to purchase. they are the only ones that have something to manage the car. i will prob get that and install before the final stage if i dont get crazy A/F ratio in after the cams and springs.

i heard that the brian crower makes more mid range power has any else ever heard this before?

why do you want atleast 12.5 compression? that should be the most you want on pump gas

what are you suggesting? is 13:1 to much for 91 gas?

in my opinion 13:1 is deff too much for pump. even 12:5 is a lil on the border for 91. we got 93 up here. and guys still throw in some octane booster in their 12:5 blocks every once in a while. i would go with 12:5 at the most. you dont wanna have to worry about detonation.
good luck with your build homie

oh, ha i said 91 and i meant 93...well maybe 12:5 is better, rather safe than sorry thanks for the help

i was going to raise the cr but decided that the stage 2 were better from another thread because the guy put stage 2 and then 3, with only small gains not worth it

I have stage 3 in my rsx with itr pistons what a disappointment

the aem piece is designed only for f/i applications it even says so on their website....it can only retard ignition, which although is good for f/i...is absolute junk for n/a....save your $ dont buy it...my .02

if you are a cant wait type of person, this would be my suggestion

jumper harness to run kpro, stock ecu to run guages....as of this moment imo this is the only viable solution
