High Compression 240?

[KA240failure]

i have an 89 with the stock KA24e in it
turbos are nice but i was just wondering if theres anyway to get decent power out of just my stock engine. ive looked into high compression pistons and new cams all that stuff but ive never heard of anyone who has good power in a 240 with out having a turbo or some bastard v8 swap.

so basically unless im made of money and have tons of time is it just pointless to build up my stock engine with out turbos?

just looking for some feedback

search its been done

[let5l1de]

Just buy all the bolt on upgrades in the world for a KA "E", install nistune, get it professionally tuned and call it a day.

[P-Funk alot]

its been done but cost is more in the long run gl

[MambaSic]

They Raced the Ka24E a little more than the DE, I believe, so Do like The guy says above. "I/H/E Cams Yada yada." Then Lose weight.

Me I vote for all Bastard swaps. Because honestly they are by far the best. Maybe you need to think about that.

Single Cam is Ok. Maybe go Carb Single Cam like the old S14 racers. Someone is gonna say im stupid. But thats ok, cause I love myself just the way i am. HaHAa

[sacco sideways]

^Stupid^ :D

[lazysk8er2]

yea its not worth it.

plus if you wanna mod a car its not cheap.

if you want a decently fast new car go lease/finance one.

you could buy one already swapped for cheap also saves time and money and headache.

or just get a motorcycle - cheap and fast.

Both the KA24E and the KA24DE are more potent engines then people give them credit for, but in the end N/A is expensive. In order to get good power from a KA you would need to at least mildly build the engine, give it a full compliment of bolt-ons, and have a proper ECU set-up. You could spend anywhere from $4,000-$20,000 building a KA depending on how radical you want to go. You could build it for cheaper if you are resourceful and know how to do the work yourself though. IMO a mildly, but intelligently, built KA would be a pretty cool thing to have and would probably bite more then a few SR heads in the ass.

[spooled240]

people that usually build a n/a ka aren't looking for raw straight line perfomance and big hp they look for response, response and more response.

I have a ka-t with a t3/t4 and I've taken my car to tight circuit tracks where response is key and I have to say that a 200hp n/a ka would probably smoke my laggy turbo ka lol

so if you want power go turbo, if you want instant response go n/a(even a tiny ass BB turbo won't give you neck-snapping response compared to a built n/a motor)

thanks everyone for there input and keep it coming

yeah my N/A 240 is just an idea put some extra horse in my car for now
cuz eventually i wanna drop an rb26dett but i dont have the money for that

my dad own's a machine and fab shop so that will cut my cost down in my build and im not taking it to any shop ill do it all myself no labor charges

and im not looking for like huge power outa my engine just more then i have right now.

im just thinking all new bearings, seals, rings, forged high compression pistons, new valve train pretty much, shave the head, new cam, injectors, fuel pump, Cold air, headers and exhaust and it'll be more fun then stock
oh and Nistune cant forget that

You forgot a few things that are important to get the kind of results you need to warrant going through all that work.

1-Mild head porting and a mildly ported intake mani.
The head and intake mani are the KEY to making power with ANY N/A engine. You don't need to go crazy here just make it better.

2-"street" cam
Without a cam (or cams) you're not really going to gain much anyways.

3-balanced & blueprinted bottom end
In the end this really isn't that expensive or difficult and it will help the engine rev better and make it a little more responsive. I would have the crank lightened as well.

[ranger240]

rb26dett is a noob unicorn..... a properly built sr20det or rb25det is the way to go

[mattro]

there was just a thread about this.......

basically the money your going to spend on making 200 na hp is more than what you will spend for an sr swap and 350hp lol

ohk buddy wanna race when im done?

well yeah i was just throwing a little list out there to get the idea but
i know i have to do all that stuff to
but thank you

LOL! Yup, that's the RB26...

there was just a thread about this.......

More like there was just a million threads about this...

basically the money your going to spend on making 200 na hp is more than what you will spend for an sr swap and 350hp lol

I wouldn't quite go that far, but in the end the SR has far too many advantages to ignore. For the average joe though the SR is the way to go if you feel the need for real power.

ohk buddy wanna race when im done?

UGH........

:duh:

[marcobleedsblue]

ka24e pistons in a ka24de 11:1 compression haha

[roboticnissan]

to the op:
im thinking of doing this as well not a super krazy build but something fun so do it and ill ask you whats up and whats down



but my hat is definately off to racepar1 he is the only unbiased dude on this site and he knows a butt load about everything!! he should be a moderator

ka24e with high comp pistons, cams and custom ITB's run on megasquirt to be cheap.

[Hashiriya415]

electric motor, and batteries in the back, hooked up to the drive-shaft with a belt should give you some decent torque. No this is not a joke, I'm talking about serious swap, find a Prius and get all the electric parts and swap it over, Just mount all the stuff in the rear.

[KA240failure]

so im thinking just do a swap on my car then with spare money and spare time build up the KA motor i have just for shits and giggles if i get good N/A power then cool if not oh well i would still of had fun doing it.
i dont race for money i just like to play with cars see what they can do so why not

Awwwww, I'm flattered... I'm pretty sure the internet would catch on fire if I was a mod though.
