Quick turbo qestion

[rubbersidedown]

i'm thinking about having and overbore done. Not sure exactly how much yet. My question is "If i overbored would i have any problem w/ the cylinder walls flexing if i use a turbo? and does the KA have any history of flexing problems w/ turbo applications?" btw i'm using a ka24de.

im not sure but wouldnt it be better not to bore it out with the turbo kit? im clueless dont mind me <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>

well i wanna try and get as much possible power out of the engine as i possibly can. i've got big plans for the car :-)

I've seen N/A apps bored out to 2.445 or something close to that. The KA's Cylinder walls a Very close together as is. I wouldn't think that it would be a very god idea to bore out the KA, then turbo. Especially since the KA is already a stroker engine.

well, i have heard the KA block if pretty strong, and there is room to over bore. But I dont know the numbers on it so I am useless as well. One thing I do know is that there is no replacement for displacement. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'> That was my domestic side speaking there. mmmmm torque. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>

if you want the power, stroke the motor, man i was going to do this but the price was unbelievable. get a custom crank, rods , and pistons and the thing would haul ass, but the ka is an iron block and can be bored alot but remember you weaken the block, and with turbo, i wouldnt risk it, but i cant state this is true because i never hear of a big bore w/turbo

I've heard that with a turbo application you want a smaller compression ratio than N/A. Wouldn't boring it out create a higher compression ratio? I say save the money you'd have to spend on a over bore and through that at a nice turbo upgrade, BOV, front-mont intercooler, etc, etc.

sykikchimp, I hope that 2.445 is mm and not inches.

Both Mark's (WeST) and PSI240SX's turbo KA's were bored over...I think .04&quot;.
Bore has nothing to do with compression.
I'd rather overbore than stroke the KA...it's already a stroker.

[sykikchimp]

no.. &nbsp;normally 2.400 &nbsp;now 2.445 &nbsp;

[LanceS13]

oh...gotcha
