sorealsosurreal Posted May 22, 2008 Share Posted May 22, 2008 ok long story short i have my 1972 240z in the garage. i go to college and am going to take an engine building class next fall. i was going to build a l31 and turbo or twin turbocharge it. i already have the l28 and the crank to stroke it. but i was thinking of other CHEAP unique options to make large power (between 400-500hp) and thought that since sr20s are constantly dropped into 240sx's couldnt i get sr20 mounts for my Z and drop a KA into it. I can pick one up super cheap. internals arnt bad price wise then i would turbo it. im sure someone has done this but i did a quick search and didnt find any pics. so would this be a good budget build or what? and are there any 6 speed transmissions that could be hooked up to a ka24? i love my 6 speed in my RSX-s (which im selling) that extra gear is just fun Quote Link to comment Share on other sites More sharing options...
Gollum Posted May 22, 2008 Share Posted May 22, 2008 I've never seen a completed KA24DET in a Z either. The KA shares transmissions with the SOHC VG motors I think... I think are the key words there. So I'm not sure what tranny would be the best option, but I can't think of any 6 speed that will be a direct fit. I personally would find it a very interesting project to follow and I hope you take the leap and do it. Quote Link to comment Share on other sites More sharing options...

The KA24 5speed is essentially the same as the Z31 VG30E 5speed, except the KA tranny has stronger internals. In our '86, my father and I got a KA trans for 100 bucks and swapped the internals into our our Z31 tranny. Quote Link to comment Share on other sites More sharing options...
sorealsosurreal Posted May 23, 2008 Author Share Posted May 23, 2008 ok so the ka trans would just be the way to go especially on a budget. so does anyone know if a KA would fit directly on sr20 motor mounts? Quote Link to comment Share on other sites More sharing options...
alexdeprat Posted May 23, 2008 Share Posted May 23, 2008 I dont know much about the engine/engines but the link below does a compare on the KA & SR. SR20DET v.s.

sorealsosurreal Posted May 23, 2008 Author Share Posted May 23, 2008 yeah i was thinking i would buy the cross member from mckinney, http://www.mckinneymotorsports.com/products i havnt heard anything bad about them so i was gonna buy that crossmember. a ka24 i can pick up a whole lot cheaper then an sr20. that and i need the motor to build for a class and the sr20 internals just seemed more expensive as well. i like the top mount intercooler but im just curious as to how much airflow you'll actually get verses a FMIC. and amoung all other things im trying to do something that isnt done often, or atleast not that ive seen. i actually live right by vildini and ill probably swing by there some time to ask some questions and see what they think or any info they can give me to help me along the way. im a technician at a shop myself so i plan on doing alot of the work myself which will cut down on costs as well.

Evan Purple240zt Posted May 24, 2008 Share Posted May 24, 2008 Make sure you get a DOHC motor.. and realistically you are gonna have to spend a ton of cash to make 4-500hp. IMO build a stock-ish setup and make 365 or so to start, you will be shocked how fast your car is with that setup. I say game on man... check out http://www.ka-t.org/forums/ Evan Quote Link to comment Share on other sites More sharing options...
sorealsosurreal Posted May 24, 2008 Author Share Posted May 24, 2008 yeah i know about the dohc, the thing is internally its going to be strong with new parts because i need an engine to build. that and building a 350hp motor and running it then knowing ill have to take it out later would just piss me off haha Quote Link to comment Share on other sites More sharing options...
AK-Z Posted June 1, 2008 Share Posted June 1, 2008 I'm in the process (prolonged process) of dropping at KA-t in my 280z. The chassis isn't ready for the engine yet. And I have yet to source a IC and haven't decided whether I want to run a tuned OEM ECU or run megasquirts. Whats really holding me back it that no one has come up with a wiring scheme for the distributor portion of the MS setup on a OBD-II engine. I came up with one a while back, but I don't want to test that and end up frying my dizzy or the MS. Quote Link to comment Share on other sites More sharing options...
