Thread: S14 with SR20 or KA24

Are you really claiming the high revs obtained by the CA18 are some how inferior to the high (but lower) revs of the SR20 because the CA18 "has to" rev high?

Yet we were talking about engine smoothness. It doesn't get much smoother than an inline six. Not to mention the RB20 internals will take much more power in stock form than an SR20 by the simple fact that the power is spread across two more rods.

You have no idea what you're talking about. The CA18 is a terrific motor, in many ways superior to the SR20. Please don't make us look like a bunch of ignorant fanboys. Thanks.

This man speaks the truth. How many more times should we cover this?

Yeah its up to you in the end, you can ask as many people as you want but in the end opinions are like as&holes everyones got one.

But on the ka-t subject i have a built one sitting at my shop if you are interested send me a pm.

nah the ca18det is a piece of crap hahaha no torque, really had to clutch kick the crap out of it to have any fun

i had one in a striped out rwd bluebird (you might not get them over there, but its cheap boxy car)

car had s13 coilovers, locked diff, t3 turbo running 17psi, walbro, supra fmic, no interior or sound deadening, aluminum dash with gauges pluged in, 4 pt harness, weight around 800-900kgs etc

my daily actually got stolen, so for a period bout 3 months i had to drive it to work everyday. Was a very fun car, but it was a cheap car with a cheap engine. I would never put a ca18 into any shell thats worth over $200

Anyway, as far as smooth and revvy, the rb20 takes the cake, if ya want to bash limiter all day everyday the rb20 is the engine for you (great wet weather slider for those that dont wanna burn tires, clutches, gearboxes etc every two weeks, but just wanna have fun)

rb26 is also very good, but from my experience the rb20 is still smoother

the 2jz is also very smooth engine with crap loads of torque, not as smooth as the former two, but considering the torque it produces it nice.

all of these are abundant here is aus, and i have personally owned 3 of them and driven all of them

check out some of the 240 sites(ka spacific) and find out what weak points are common

OK then!

having been part of both a sr20 s13 (ok, we just swapped turbos, but....) and a ka plus turbo s13 (hes been trying to get it running for....i dunno over a year), and another customers s13 ka turbo, one i worked on at the shop. my opinion of the s13 chassis is kinda low already, but if you HAVE to have a car that comes with a dog of a motor from the factory......well, you might want to swap it out. one way or the other, the ka will need work. AT MINIMUM a head gasket, after all the ka 240s ive seen friends buy and then the head gasket fails a week later. THEN, if your going to make more than 300 hp, you better build it. i dunno. MOTOR for MOTOR, the ka is WAY inferior. terrible head flow, weaker components, wont rev worth a crap......i could go on and on.....and this IS talking from first hand experiance, theres probably 3 o4 ka's that are within a 10 mile distance of my house, they are broken down, the motors keep failing, they are DOG SLOW with setups that would make an sr SCREAM. ive ridden in multiple "built" ka's, know of one thats broken down right now, worked on a few, and ive ridden in multiple sr with boltons.....and they scare the piss out of me. i guess the ka scares me too, but, thats because im not sure when/where its going to break down. my first hand experiances say DONT waste your time with the ka. if you do, dont say i didnt tell you.

You pretty much just described Andre's (EMS Dre) set up on his 240. That car when I was back home ran like a monster.

i am just stating what ive delt with first hand though, not trying to be an ass. anything can make power when built right....i just think the amount of work that would go into a ka could better go into stroking an sr. just my 2 cents worth. if it was ME and i had a s13, i would just go with a 4.5 litre q 45 motor. THAT would be as nasty as a ka on boost i think. at least close to it. ok i know, off topic, i just had a huge conversation today with someone about this.

^^ or you can always do an LS?^^
