i need more low end torque, help please, ideas?

[krazydriver]

if you've got an electric fan setup sure, pull the clutch fan out.Early on i'd wired the AC fan to run whenever the engine was on, which worked fine. For better results get a thermostatic controller that turns the fan on at a certain coolant temp.

Hype, removing your fan and replacing it with an E-Fan frees up enough power to where you feel it instantly. That means it gives you between 5-10 hp. This is just a proven fact dude.

If you want more low end, save your cash on minor ka mods and swap a LSx into your 240 and be happy. Your just never going to be happy with a Ka's low end if you want big Tq.

Or you can go with a 1500 dollar turbo setup thats pretty popular now adays, and have huge gains between 2500-6000 rpms.

removing the clutch fan WILL make a difference.The clutch is thermostatic, it doesn't freewheel while your driving. It's constantly spinning with the engine, it only FULLY locks when the fan clutch gets past a certain temp(what that temp is idk).You will feel a difference in how fast the engine revs.

Alright, I know when I'm beat. I guess I was wrong. The thermostatic thing makes sense - its not an on or off affair. Thanks for clearing that up. I still doubt 5-10hp, but I have some efans lying around, maybe i'll throw em on and see for myself.

ok thanks again ppl. well i'll probably take the fan out then, and find an e fan to put in. but does anyone know where i can get a decent 5 speed ka-de dohc ECU. cause my 240 keeps shutting off while i'm coasting cause it still thinks its an auto, and is confused about the rev limit it will need to not die when i stop at the light or somewhere.

HA I KNEW IT lol, and i was starting to doubt myself lol

just adjust your idle, i had that problem too when i installed my fans

Yeah I'm definitely not infallible, but I generally only open my mouth if I know what i'm talking about. When I'm wrong, I admit it. Give my misunderstanding of the clutch mechanism, it makes sense that it gives some power, but i still doubt 7-10whp If you can find fans cheap enough and wire them up well, sounds like a worthwhile mod.

i checked with another guy who took that off his s14. said he got 6whp from just that. i dunno how much power that it actually gives but its still something

but hey at least you admit when your wrong, most people would keep going and going lol

well my is idle already adjusted to rev at 16x1000 rpm's. so i don't think i really want to adjust it more because i'm using to much gas to just keep it at the correct idle.

Check your grounds and/or add new ones. Also check for vacuum leaks. Since you have modded both the electrical system and intake system, you may have introduced a fault in one or both of these areas. Grab the FSM and a multimeter and test your TPS and CTS if that doesnt find anything.

I read a couple posts and decided to post this link. I don't know if anybody has posted this yet so don't flame me, :-P

As others have suggested though, I recommend you do some reading before you attempt any modifications. Fix up some stuff, your money will be much better spent. Distributor cap, rotors, plugs (plain copper are fine, NGK BKR5E I believe, but you can spend the money for iridium if you really want), NGK plug wires, 300ZX fuel filter, air filter replacement (or an ebay intake will work well), pcv valve replacement, oil change, transmission oil change (or auto trans service), set ignition timing, fix chain timing chain rattle, clean/improve engine grounding, bleed clutch and brake fluid, eliminate clutch dampener..... all those are great places to start and are possible with just a screwdriver, a 10mm line wrench and a socket wrench w/ 10, 12 and 14mm sockets. Grab the FSM, keep reading and get wrenching.

Is the 300zx fuel filter a good mod even if your car is N/A? I ask because I'm going to change my filter soon....

IIRC, the 300zx filter is sometimes cheaper, and since it flows more, it is a good mod. It shouldn't matter if you're NA, since its not going to change how much fuel is pumped or used.

i use one, no problems here

another thing that i'm gonna try is the 248/232 cam swap. You get an exhaust cam from a 95 s14, then you replace your stock exhaust cam(248) with the 232. And then you replace your intake cam(240) withe the 248 exhaust cam. There's a whole write up about it, but the gain from what i read are very good for low and mid range. I just bought an exhaust cam from a s14 for $40 shipped.

zerothread?id=294891and check this out as well

And finally if you want to do this mod you are going to need to drill the cam sprocket for 2.5 degrees of advance

I hope this helps
