Dropz Posted September 30, 2009 Report Share Posted September 30, 2009 (edited) Hey all, I've recently acquired a KE70 with the gutless 4k as my new daily driver. Anyway, as always the lack of power is really frustrating, and I've heard many people do ca18det conversions to their xE7x's without much trouble, which has lead me to think that a ca20 would fit. I was wondering, since its just my daily car and not some 'Fooly siiiik drifta' would a ca20 conversion be worth it just to get a little bit more oomph without going big bucks? And, if I choose to go a ca20 I'm thinking that I may throw a ca18 head on. Have people ever tried anything along these lines, and what were results? Also, what other cheap conversion options do I have, I would like to upgrade to EFI as I'm not a fan of carby's, which rules out a 5k conversion. Any feedback is welcome, good or bad :P Thanks, Karl.

Any feedback is welcome, good or bad :P Thanks, Karl. mate the ca18 conversion is not straight forward as such but has ALOT more going for it than a ca20... the ca18/20 hybrid conversion is not something to take on lightly and is not just a "slap her together" process as such... imo not really worth it if your after cheap performance definitely go a 4AGE conversion in any of its guises, for ease, bang for buck, aftermarket support and general info on the conversion you can't beat it... keeping in mind you are going to efi so you will need custom wiring, fuel system including lines, exhaust, mounts, diff conversion or welded centre (cheapie :rock: ) brakes etc etc... none of this will be done by a novice ( assuming you are ) over the weekend unless you have super keen, knowledgable mates willing to help out... if you really don't want a 4AGE and its your daily driver then buy something else and work on it in your spare time... :wub: hope that helps a bit Quote Link to comment Share on other sites More sharing options...
Dropz Posted September 30, 2009 Author Report Share Posted September 30, 2009 righto. i was only thinking of a ca20/18 combo as i always see ca20s at the wreckers, and cheap cheap 18 parts.. ive had a few mates try and talk me into ca18det as I'm into the R31 scene and can get parts for it pretty easy but i can't afford to spend that much just yet, and if/when i do it i want to do it properly (get a mod plate from regency) i can stay carby if it saves me money. my plan in a few years (after i've finished my r31 project) was a tossup between ca18det or 4age. but for now i was just after something me and some mates could get in over a weekend or two for around $900 as its all i have left lol :P Quote Link to comment Share on other sites More sharing options...
redae71 Posted September 30, 2009 Report Share Posted September 30, 2009 ive seen people bolt a turbo to a 4k for less than that :P Quote Link to comment Share on other sites More sharing options...
Taz_Rx Posted October 1, 2009 Report Share Posted October 1, 2009 Yeah my orginal 4ktc setup cost be about $400 to get 6psi up its guts. I did have a few mates donate parts (like the turbo) for free though, which sounds like it would be too hard for you with nissan driving mates. FYI - Wanting EFI doesn't rule out a 5k. My turbo 5k is running KR42R townace EFI of a 7KE. You can also get 4KE systems but they're harder to find, more expensive and not as good as the 7KE gear anyway! The 7KE EFI gear cost me $250 from a commercial (vans and trucks) wreckers. Click "TAR" in my sig for more info. Quote Link to comment Share on other sites More sharing options...

philbey Posted October 2, 2009 Report Share Posted October 2, 2009 Man a CA20 conversion will be a lot of effort with bugger all gain. Given that it's effectively the exact same setup as a CA18 you might as well go with the 18. Same engine and gearbox mounts etc. Quote Link to comment Share on other sites More sharing options...
Hiro Protagonist Posted October 2, 2009 Report Share Posted October 2, 2009 Man a CA20 conversion will be a lot of effort with bugger all gain. Given that it's effectively the exact same setup as a CA18 you might as well go with the 18. Same engine and gearbox mounts etc. After seeing Candellan on Twincam.org do a _very_ tortuous, long and expensive CA20DET build (and this was into a S12 Gazelle, the car that the CA20E came out of), I wouldn't recommend it for anyone bar the most die-hard CA tragic who has a lot of time and a lot of money free. For pure gains it just isn't worth it, however you do end up with something fairly unique I'd be more interested in doing a RWD KA24DET :) Quote Link to comment Share on other sites More sharing options...
Sam_Q Posted October 2, 2009 Report Share Posted October 2, 2009 yeah rwd ka24det, I am sure we all would be interested in that one! I may make sr/ca mounts in the future if your interested Quote Link to comment Share on other sites More sharing options...
Hiro Protagonist Posted October 2, 2009 Report Share Posted October 2, 2009 (edited) yeah rwd ka24det, I am sure we all would be interested in that one! I don't get the lack of love for the KA, it's a nice strong torquey motor, and can be grabbed for cheap from the U13 guys ripping them out to put SR20DETs in. RWD gear can be had from the D22 Navara (much easier to find in Aus than S13 and S14 240SXs) Edited October 2, 2009 by Hiro Protagonist Quote Link to comment Share on other sites More sharing options...
Sam_Q Posted October 2, 2009 Report Share Posted October 2, 2009 oh interesting, I will read more into that Quote Link to comment Share on other sites More sharing options...
oh what a nissan feeling! Posted October 3, 2009 Report Share Posted October 3, 2009 I don't get the lack of love for the KA, it's a nice strong torquey motor, and can be grabbed for cheap from the U13 guys ripping them out to put SR20DETs in. RWD gear can be had from the D22 Navara (much easier to find in Aus than S13 and S14 240SXs) I have found a whole lot of love for the ka in the US, they hold them in quite high esteem. The main bummer is that being a 2.4 it is not a legal conversion in QLD (with a turbo) for any ke3X or earlier model car. I have seen inside one while my old man was building it, they are almost identical to an sr with their setup internally. Quote Link to comment Share on other sites More sharing options...
quest Posted October 3, 2009 Report Share Posted October 3, 2009 not sure what u were looking at, but inside an sr20 is nothing like a ka24de has shown itself as nissans' monster of a 4cyl, over this way = lotsa torque Quote Link to comment Share on other sites More sharing options...
Sam_Q Posted October 3, 2009 Report Share Posted October 3, 2009 must have a long stroke or something Quote Link to comment Share on other sites More sharing options...
Hiro Protagonist Posted October 3, 2009 Report Share Posted October 3, 2009 must have a long stroke or something 89x96mm, it is a truck engine after all :) Kinda equivalent to a 3RZFE of sorts, except undersquare. Quote Link to comment Share on other sites More sharing options...
