So im in the same boat as many of you. I dont have much money to spend on my car and i want to go fast but still be reliable. I didnt think that was possible until i saw a new way of utilizing the non vtec exhaust rockers of “economy vtec” engines. My goals for this build are to use as many oem parts as possible. I believe everything internally will be oem except for ARP head studs. Anyway heres my build and i hope it can be a guideline for many of you. If you have kpro and wanted to do this to your ep3 it can be done for under 250dollars. I will take plenty of pics and videos as this build progresses. I wasnt going to post this up but its almost done. I just need some time and bearings from honda. Im not going to give any estimates but a stock compression k24a4 running a2 cams put down 234whp and 180wtq and went 13.1 on street tires. Anyway hope you guys enjoy the build as much as i am. Ill post alot up over thanksgiving break, i have so much work for school right now so i might not be able to answer all your questions about the setup.

Ill probably upgrade my shitty obx header to the kiddracing setup as well out to 2.5 inch piping and an obx twinloop.
Few teaser pics:
These puppies make it wall work along with my A2 cams

Already modified and ready to go. Thanks LKSI
TSX pistons ready to give me a bump in compression
I took the liberty of removing those bullshit k24a1 cams and rocker assembly already
Its got frivilous hair precision lol. I put it on the other night and its beautiful. Half the people who read this thread arent going to understand the setup.
haha… he did a good job on it, he seriously probably had to go at the thing 15-20 times, constantly checking to see if it was good or not. Then I just bought the s2k pump, he was riled.
Nice build thread you have there. Should be fun once you get it done. You might be able to get away with the 310cc injectors but might want to think about upgrading in the future
Well since the ECONOMY vtec motors k20a3/k24a1/k24a4 only ride one lobe on the exhaust side. So basically im running exhaust rockers on both sides of the head. Now that ive switched to an ivtec cam you run on the vtec lobe all the time. hence the term vtec killer setup. This all using oem parts. Its relatively new and very reliable.
13.1 @ 105. The owner has since ran slicks and managed a 12.8 @106. Ill have a nice bump in compression over him also. Im not too concerned about the 1/4 mile though.
