i just signed up and searched and came back w/pages and pages and cant find one, anyone have a flow chart of a k20a motor ? bone stock motor, or if you have one w/work done just list what was done, thanks.

I have a whole bunch... k20a2 head, k20a head, ported k20a2 head. they're at the shop though i'll try to get a couple and scan them.

cool thanks, i appreciate it

actually on a related topic does anyone have a dyno sheet resembling anything close to this setup:


port and polished head
crower cams stage 2 ? or whatever gives most power but still streetable
flat valves (dont know if they are made for this motor yet)
k24 block
hondata
compression at 12 or 11.5:1

will it make better than 270whp ?

i dont know exactly what is made for this motor yet or what most of you have done but im looking to put it in a teg, want to see some numbers so i can get an estimate if its worth it to go NA

not 270whp SAE, but possibly 250 SAE... the most important parts are not listed. the longblock can only product what you allow it to breath through.
Header combo and intake choices make huge differences.

well i figured that was a given and variables like that will change from mostly person to person, so im looking for the best results


thanks again for the flow charts

Im just curious, but who does the best port/polish work out there? Ive read about all these people making alot of power from port/polish work...just wondering who does the best work out there?

im from ny, i have heard alot of guys around here send their heads to places in cali, i use a shop i trust and uses a flow bench that is pretty local for me, they do all paisleys supra motors so they know toyota's very well which is what ive had them work on, i dont know where your asking about ?


it surprises me the setup i posted wont make more than 270 w/just that stuff, would the s2k crank help the rpm's that much or is the 2.4's stock crank already ok to rev enough to keep up w/the cams capabilities ? ive seen what the stock type s motor can do w/bolt ons and hondata so i figured upping the compression, cams, valves, and a bigger bore would kill the stock numbers

The power you seek is definitely attainable. We'll show you soon.

So how much power can be made by porting a Stock K20A-R head? I'm on a quest for power at te moment, before I do a full rebuild..

If you are running a reasonably sane compression ratio, and fairly mild cams (TODAs or smaller), there is not much power to get from porting the head. At least this was my personal experience.

the setup im looking to get will be a "daily driver/second car" if i go thru w/it, its a high goal but im looking to make around 290 on pump, i wont get all the parts ready till i know it will be worthwhile and realistic, it would still be worthwhile to make 270, but im gonna wait and see which cams make the most power etc...

MAX_CFM has seen +17hp as a result from the head I sent him late `03.

I concur.

can i get some pics of it?? and is that with your k-ips cams??

No this is what Brad told me himself. He didn't give any specifics other than that it was on one of the race motors.

Brad Z is the man!!!!! 8) especially when it comes to port & polish jobs :wink: I hope to have some work done by him (maybe next year)

Does anyone have any results from porting a K20A head???

Be realistic come on you will not have 270 whp..

im from ny, i have heard alot of guys around here send their heads to places in cali, i use a shop i trust and uses a flow bench that is pretty local for me, they do all paisleys supra motors so they know toyota's very well which is what ive had them work on, i dont know where your asking about ?

You will not have never 250 or 270 whp with just changing pistons,valves , porting etc lollll come on make a sense man, i have a b18c5 turbo 11:3.1 compression ok my timing is retarted but whatever i have 215 whp soo i dont think soo with a k20 you gonna have 270 whp
