need some help

[gtrider4life]

hey im needing to no if anyone knows any cheap ways to get some low end power for my vert. And if u no or willing to sell me any parts and what not please let me no.

thanks

Auto to manual swap, and switch the diff to an R32 Skyline diff.

[gtrider4life]

yea i have been wanting to do a 5 speed swap for sometime now. do u no the size of the stock injectors by chance and what size u pefer for an upgrade

upgrading fuel injectors will only harm your engine unless you do it to keep up with a turbo or supercharger kit.

Start with a cold air intake. They are cheap and easy.. may not help much on the dyno, but you'll notice better response.

[gtrider4life]

yea i did a cold air and exhaust but i just have now low end power. I want to put some upgrade cams in but dont want to spend a whole lot of money. Im really looking in to a super charger kit but i dont no anyone that has put one on an had it work so if anyone no if a supercharger will work let me no.

Supercharger!

Or.. slap a turbo on there.. not the best for low end power.. but not bad either. Hit the KA-T forum for that.

Ask Dexter about the Cam swaps.. he's got those things figured out as well as anyone I've seen.

The one thread that seems to have tons us useful information is a year old and never really did go over total HP gain.

I did an eBay search and all I came up with was an electric superchargers - which looked to be no more than a fan mounted inside the air intake and switch to turn it off and on! Too funny.

Anyway, you pay for power either turbo or supercharger, I just wonder about the pros and cons of each.

Happy motoring!

A 5-speed swap will give you better access to the existing power but what does a differential from an R32 Skyline do? Better distrobution to the wheels equals more power off the line?

I actually disagree with this theory. I don't think an LSD will help until you have at least 200hp or more. LSD's are great to get you off the line if you are in danger of spinning your tires from too much power. But until you reach that point, they do nothing to help.. in fact probably hinder a bit.. anytime you add more gearing and/or indirect gearing, you lose power to friction.

[cmkelly]

that's kinda what I was thinking and why I asked. Lord knows I can only spin my wheels on gravel from a stand still. Seems to be easy in reverse though....

[ishkabibble]

Skyline diff has a different gear ratio. It's not about LSD. The trade-off is you gain low end power, but the car cruises at higher RPMs.

There aren't many options to make cheap, singificant low end power.

[cmkelly]

Good to know plus you can't argue with anyone with a pancake on their head.

Low end power = quest for the holy grail

i suggest driving a stock, automatic, non-vtec honda for a while. or maybe a 3-clyinder geo metro. it'll make you appreciate that extra ka24 displacement a little better.

definitely spend some time in the ka forum. there's only so much we can do to the n/a ka before either dumping a lot of money into an n/a build or going with forced induction.

just do the basic bolt-on's: intake, header, exhaust, pulley. if you're still not happy, do the "hot cam swap". of course, the 5-speed swap with a light flywheel will make a big difference too. a crank scraper isn't a bad idea either. another tip is to get some lighter wheels. at this point, a reflash, a rom tune, or a piggy-back fuel controller would probably be the best thing to do. lean out your fuel/air ratio a little bit and adjust your timing and spark plug gap accordingly. that's about as far as you can get before you start having to make big investments. with these mods you'll probably have spent a few thousand dollars.

if you still want to stick with n/a, you're going to have to start building up your engine. bigger cams, adjustable cam sprockets, higher compression pistons, individual throttle bodies, bigger fuel injectors, and a standalone ecu. there you've all ready spent up to $4,000+. that's just for parts. that doesn't include the cost of machining and rebuilding and tuning.

if you really want to get crazy, go with all forged internals with a knife-edged stroker crank. this will further reduce the spinning weight and free up more power to deliver to the ground as well as allow you to get even higher compression ratios. another nice touch would be to add a 1-piece aluminum driveshaft. of course, you'll need to stop running pump gas and will no longer have a streetable ride. there goes another few thousand dollars. while you're at it, put that pig on a diet by removing the top alltogether, gutting the interior, and putting a racing seat in there.

you still will be hard pressed to hit the 200hp mark (aka. the holy grail). and you'll have ruined a perfectly fine vert.

something that doesn't get discussed much in the 240 world (at least as far as i can tell) is the use of an n2o system. put some spray on the ka. compared to $4-10,000, nitrous oxide injection is a lot cheaper and easier way to make 50hp. heck, with that kind of price, you could make upwards of 3-400hp by rebuilding your ka for turbo and slapping a snail on there! or even doing a motor swap (vg, vq, vh, vk, sr, rb, sbc, 2jz, etc.)

keep in mind though, in the end, you're still driving a 2.4L I4 engine. if you want big low-end "power", get a bigger engine.

again, spend a couple hours reading the ka forum. there's lots of good info in there. hope that helps.

Dang son! We need to get you a hobby. Wait, it appears you already have one.

This is all great info. I think what gtrider4life was looking for was what we're all looking for - some magic bullet to get them off the line faster. Once moving I love my 240. There's just no kick in seat but like you said, it's still a n/a 2.4L engine.

The super charger probably has as many issues and $$'s associated with is as does the turbo option.

[biggie]

The KA NA as a 5 spd is 100x better than the auto, most won't complain too much with the 5spd.

A simple T28 SR-type setup would be good for getting off the line, that turbo spools so fast on the 2.4L that it feels NA with more power. Just falls a little flat at the top end.
