I need info on KA NA mods

[BuddhistWitch]

I want some info on what mods to do on a KA NA. All I can find on any forum or any search i put in is mostly SR with a little KA-T in there. Anybody with any knowledge of mods to do to a KA would be greatly appreciated.

BTW its a 93 240sx SE with a KA24DE in it. I haven't bought it yet, because I want to know what potential it has without a turbo. And don't think I'm a dumbass and don't know turbos. I know the KA was built with the intention to turbo it, I would just rather spend the money elsewhere.

[SR20DETpower]

Id say you could get into the 13's with natural aspiration, drivetrain mods, and some weight reduction.

The head is pretty free flowing, I would get some Titanium Valve Springs and retainers from Ferrea. I would get some aftermarket Stage II+cams. Header, test pipe, 60mm catback, Throttle Bodies or a Cold Air Setup, higher compression pistons, underdrive pulleys, and a ecu tune/stand alone.

lightweight Flywheel, Stage I/II clutch, lightweight driveshaft, Quaife Differential, 245 sized tires, lightweight 16"/17"*8" wheels, Electric Fans, Electric Water pump, remove Air Conditioner.

thats it in a nutshell, plus weight reduction

this wouldn't be that great on the street, Ultimately a turbo ka should beat you, on a race track or auto cross, I think the NA setup is better.

[BuddhistWitch]

Yeah, I'm not completely againt Track or Autox, I'm just sayin that this is also gunna be my DD. I got nothin against showin it off every once in a while.

Oh, and negative on removing the AC. It hits 100+ here durin the summer.

Thank you for the advice, but could yoiu also list some preferred brand names.

And also does anybody else have something to say? Or is SR20DETpower the only one who knos anything about KAs?

[Soyo]

well he pretty much covered a lot of stuff, but just to go over my list of things I had when I was planning on buying a 91 240sx with plans to go N/A... so this is some stuff I got... companies are just my opinions:
Fluidyne radiator
thermotec cooling material
port and polish and rebuild the engine(pistons, rods, gaskets, valves, cams, etc.)
jim wolf technology ecu
hks or apexi exhaust
high flow cats
K&N intake with customized piping and custom cold air box
downpipe
hotshot header
bigger injectors
Tomei fuel pump
fuel rail
NGK, Denso, or Splitfire spark plugs
Nology or accel ignition wires
Greddy, Unorthodox Racing, or ASP pulleys
Apexi AFC (air-fuel controller)
lightend flywheel
B&M short shifter
flex-a-lite electric fan
alternator


well thats about all I can think of at the moment, but good luck if you decide to do it, I think it would be a fun car, just get it to 200hp and do some weight reduction, let us know if you buy the car or not

[BuddhistWitch]

Yeah, my goal is actually to hit 200+ hp, and it can be done. Right now I'm thinking:

Radiator - OEM/Fluidyne
Cooling Material (Maybe) - Thermotec
Rebuild (last thing I'll do, it doesn't need it)
ECU - Jim Wolf
Exhaust - Apexi Dual N1's (Most likely)
Cats - Don't know
Intake - Injen (Most likely, but K&N's look good too)
Headers - Hotshot
Pulleys - Unorthodox
Fan - Still deciding
Alternator - Still deciding

Most of this was from Soyo's advice, and some were my own preferences. If I didn't include something then it either doesn't need to be done, I don't feel like I should have to, or I still haven't concluded which to use.

Anybody elses advice or opinions would be appreciated, I can't just go off one person.

[SR20DETpower]

yeah 200hp can be done easily i think. up your compression 1 level, get all the bolt ons, and get some cams with titanium valve springs and retainers so you can rev higher. The new cam will allow you to rev high so you have to take advantage of it.

injen intake?? NEVER EVER pay for an intake....

make your own short ram cold air

[BuddhistWitch]

Yeah, injens are expensive. But ppl who I know who have them say they're worth it.

[SR20DETpower]

yeah an injen is gay, if you are going to stay naturally aspirated......move your battery to the back and make the intake goto the passenger side front of car. Shorter tubing, less heat soak, and a more direct route into the throttle body. do it right, K&N filters are the best, they can be cleaned and used forever, don't buy some cheap 10 dollar shit off ebay if you are really going to use the filter and keep it for a long while.

[stealthj]

im tellin u, MAKE A WHOLE with a dremel or something where the battery is and do a COLD AIR SHORT RAM!!

is da shiet

I already knew I was doing a cold-air. And I'm getting mixed feelings about injen vs. K&N. I just decided fuck injen and I'll either do custom or go K&N.

i put down a wopping 140hp at the wheels. i thought i had the fastest car in the world, until i took it to the track and ran a 17.2 with the interior completely gutted.

sure it was an auto and a single cam, but there's not much difference between the 2. if your going to put money into a 240sx either turbo the engine or swap it out. there's no way you can get a n/a past 15's.

no way. don't even try.

[Nova3465]

I tell ya what... If ya go to PlanetPerformance.com and go by vehicle type then you can get an extra 140hp from ECU upgrade, ECU controler, new cat. conv., Headers, Full exhast, Pullys, Ignition Amp., and a k&n filter. They show how much HP you will gain when you look at the product too. All of it costs about $1300 and if you put a 75 shot of Nitrous on it you will be putting out a total of 355hp. realnissan.com also has turbos that will add around 200-250hp.

[BuddhistWitch]

Damn... I completely blanked about PlanetPerformance. I haven't been there since I helped my friend with his supra.
And also ka24de.com has decent stuff too. Only because it's actually custom built for the KA.

sorry man, but those mods aren't going to do shit. intake+header+cat+exhaust=dick without a/f adjustment. you're probly running hella lean because you're able to get more air in and out easier, but your injectors are still injecting the same amount of fuel that the stock restrictive intake and exhaust allow.
even with a/f adjustments, they aren't going to add a whole heck of a lot.

with some worthwhile mods like high compression pistons and cams, you can get over 200hp.
