Potential of a ka24de engine

[fulltimeclubber]

I originally planeed on going with a sr engine but since more and more are going for that I am now more interested in swapping a newer Ka engine into my car. Now I have a 90 and would have to change the ecu in order for my car to accomodate the dohc but thats fine still cheaper in the end. My question is with all this done to a Ka engine rebuilt with better pistons, headers, boring it out, and other mods such as intake and exhaust and other internal mods I dont know of yet. Would it be possible to get 200+ hp out of that engine, and if yes would it be readily suitable for a turbo as well? Maybe noob questions but they are big concerns to me because I will probably be doing just this in a few months, that is only if its all possibly, thanks for any input guys.

You can easyily get 200+ out of the KA, usually with just bolt-ons. This egine has some serious capabilities and if you turbo charge its almost limitless

no you can't. not even at the crank.

Yeah no way are you going to make 200hp with just bolt ons.

But the KA is very capable of hitting 200hp. Just not with only bolt ons.

Search the board, it has been discussed.

Also check out dauntt's site, http://www.afterdarktuning.com

He has built-for-turbo motors and NA KA's that can make 200hp.

so it is possible, great. I understand that it would take more than just bolt ons and a little bit of internal work but its worth it in the end and still cheaper. I am simply lookin at the situation like this, 2600 for an sr engine or like 2600 for a rebuilt ka24de engine that puts out 200+ hp without a turbo? Hmm I know what I want, beating a 99 prelude sh and tellin the guy I dont have a turbo then watchin his mouth drop

[Exar-Kun]

I would just build your engine in "pre turbo" things like I am doing.short ram-intake, exhaust, high flow cat, upgraded fuel sysetsm, clutch, flywheel, under drive pulleys, suspension and differential things...

stuff that will help NOW and if you decide to go turbo later.

but thats just my opinion.-chet

All of my mods can be used with turbo exept my exhaust. The muffler can still be used.

[fulltimeclubber]

I do plan on getting a turbo eventually I just would like to get her up to sr power without running any boost at all, I know with enough money anything is possible, I think but am not sure though that with a bugdet of around 2000 (after the engine is bought, and not including installation that I could get 200 hp or so at the wheels, any opinions on this? Besides I dont want to go to the store to buy a 2 litre bottle of soda and think wow thats how big my engine is, so I think I'll stick with the 2.4 litre,

200hp at the wheels for 2 grand?

it'd be a stretch hitting 200 at the crank for that.

[Drift Machine]

If you plan on going turbo, then don't try to improve it's NA power. It's a waste of money.

But if you are going to stay NA, it's unlikely that with 2000 dollars you are going to hit 200 HP at the wheels. Unless you have some really good connections

[I am Technoman]

I think 200RWHP is possible with the right compression the right fuel and the right air mixture.

[fulltimeclubber]

Decent connections but not the best out there, 2000 grand is an initial estimate, I would mostly be paying for parts and with any luck not full for all of them, a friend of mine is goin to hook me up real cheap for the labor and I'll be along side tryin not to screw **** up while tryin to learn more about my engine. I dont see it as a waste of money, what I see as a waste of money is buyin an sr engine then payin another 1500 or 2 grand for a bigger turbo, when for that price of an engine and new turbo you can make a NA KA engine and buy a turbo for it, and most likely end up with more power over all. Besides if you needed a part for a sr engine wouldnt you have to order it special? Couldnt go down to the local Auto Zone for a thermostat or find a hub bearing assembly at the junk yard (that was hard enough with a 90 240).

[I am Technoman]

I would say you can get 99% of all SR parts mainly from the FWD version here in the states. or from other Nissan motors that share the same parts. I cant think of anything you cant get for an SR now days.

[drifter]

And part of going NA means changing the intake manifold too, which can be expensive...

Why?

[Exar-Kun]

I was about to ask the same thing, the KA intake manifold works very well once its ported...

[GatorS14]

how hard was it porting your intake manifold?what did you use?

[Exar-Kun]

-I dont know.-tools.

I ahvent ported MINe yet, but I've seen the results of a ported KA manifold, all you end up doing is increasing your high RPM flow (and high end HP), while maintinaing the nice torque band the KA is known for....its pretty sweet...-chet

[I am Technoman]

If you have the money I would recommend having it ported at a machine shop. They can do flow testing on it.

[lessthanjakejohn]

You could probaly make it to 250 if you carbureted it

It might cost you 10 grand. You could get some money back on it by making some bets..

[WHIZZN]

why use carbies when a quad throttle body setup would **** all over itmight cost more but damn.............think of performance factor

Im not sure what quad throttle bodies do?:help

[Dattebayo]

well for sure jsut from look ing at the sr20's gti-r more throttle bodies would give better throttle response. i dont know about 4 though thats like oh sh*t thats unpresidented.
