So ive been into the 240 scene about 7 years now and beleive it or not owned the same one and same ka. Has blown twice, first time uncle helped and i didnt know much and he didnt tell me there was more we shouldve done like, ball hone, decked head, and i dont remember what else. Eventually overheated again due to [email protected]
napa thermostat. Since then everything has been nissan on car and did a full engine rebuild about a year or more ago. Everything nissan, rings, thermostat, full gasket kit off z1 motorsports, had crank polished. Clevite stock bearing. Plastigauged, in spec, compression test was 185, 180, 185, 188. That was 2012 and hasnt been checked since. Has around 35-40,000 miles on it id say and still looks clean with oil cap off. See bright silver haha, now reason for this "story" is i wanna know does this soubd like an.engine suitable for a 250-300whp build maybe little less. Ill save and would like good parts and maybe build this for low hp but if i wanna up boost maybe have a secondary tune, i dont know yet. Also not nissan chain or guides was an ebay kit for like $80 long time ago :facepalm. Wanna buy nissan guides and chain also upgrade from stock radiator to mishimoto cooling set. Also wanted to mention sometimes idles surges from 750 to 400 up and down, weird cause its usually at 750 everyday and i smell gas. No egr and im not sure if i have my gas tank line open or capped opps....and have replaced two injectors over the year. Do feel like i go through alot of fuel to and smell gas more and tip on exhaust has black all on it. Have another ka and wanna swap iacv to see if t.helps idle but it goes away for months then randomly return, car ran great today except gas smell lol. Sorry for the novel and if this post needs to be moved idk how. Did this on phone anf any info would be greAtly appreciated. I dont post alot, more like read everything i can about ka and turbos lol. Thanksssss
p.s. Id like to keep all this stock if possible. Dont wanna rip engine apart again and have to bore cylinders and buy rods and pistons abd all that. Kinda just wondering if this seems like a good platform for a mild boost and also remember machine shop said they saw a cylinder taper in cylinder 3 but me and friends looked at it and really couldnt notice it or see it and so far i dont think theres anythibg wrong there.....also said he wanted to.replace an exhaust valve cuz saw small line on one, idk if he meant crack or what but he ordered wrong one and never.got replaced, also this head had a valve job. Think just basic was while ago.
