ITB question

[SlidinSideWayz]

so a long time ago i was on another 240 forum..and this guy posted a huge thread on him making ITB's for his 240...and ive been looking and i cant seem to find which thread i was on or where it was....anyone know of where it is? ha

[kane2g]

I think NICO and Zilvia had it
IIRC it was using GSXR 1000 ITB setup.

There is a local guy thats doing it with megasquirt for engine management. Pretty cool project.

[driftking777]

^^^hes correct GSXR ITB's, you can also find topics and how to's on ka-t.org

[SlidinSideWayz]

yaaa it was using those throttle bodies. and thanks ill take another look on there

NA KA is the fools errand

you're talking about scooters car

it made 160whp finished with ITBs and Haltec.

Then he turboed it and it made 350 and blew up in a day.

160whp with ITB's, generic header, and no tune just a megasquirt to get it running without a MAF.............. which is pretty good actually on anything but a Honda K series lol

stock cam, stock weak compression... stock weak SOHC head.......

the SOHC is a proven N/A performer........ its the DOHC that has yet to break the 200hp barrier... there are 270hp SOHC n/a carb'd 2.4's........

biggest gains on a SOHC are heads/cam/compression... the heads need work... someone with money will spend it on lightening the crank...... another area with lots of good gain

10.5:1 CR, BIG cam, header, ITB's, TUNING!!! solid rollers, extensive head porting and you are in the area of 200+hp easily

keep in mind stock SR20's put out 165-170whp

also the suzuki ITB's to use are either off a 750 or 1000, and it must be a 2001+ model... you can find on ebay for like 60 bucks sometimes, get an intake manifold out of a junkyard, chop it, run rubber connectors, custom throttle cable, then figure out a way to make it work with the computer... thats really the hardest part


real men drive N/A

leave the hair dryer's for the women

do you know how much all this headwork your talking about is? and lightening a crank usually requires re-hardening and def a re-balance. Cutting a crank down either knifeedged or v-cut will run around 500-700$ alone.

Turbo a KA for 1500$ and ill make an extra 40whp more than your setup. NA 4cyl are a joke IMO, unless your putting the motor in something that weighs nothing (IE hatchback civic..)

I do like the idea of a ITB KA, but what your talking about with that much work into a KA staying NA just seems like a waste..

[Fla240sx]

you can get good headwork done on a KA for 500 bucks or slightly more...

its not how you do it its who you know.......

the KA only has 1 head and its aluminum, so it makes it cheaper then say porting some v8 heads.........

also 3 valves.......

smoothing out the intake and exhaust runners in the head makes a world of difference as they are very sharp edged and have LOTS of room for improvement.........

like I said, if you had money....... knife edgine the crank is a good idea, still 500-700 dollars is cheaper then what a good GT series turbo costs, in fact almost half........ if you have money, 500 bucks isn't a lot.......

also please show me a turbo KA setup that actually reliably makes 350hp for 1500 bucks and doesn't break down within 6 months........ sure you can piece together a bunch of chinese knock-off pieces of crap that just constantly break on you and force you to eventually upgrade every part of the turbo system to a higher quality part....... like waste gates, blow off valves, manifolds, intercoolers, connectors, fittings, lines, boost controllers, etc etc...

a used maf, cast manifold, injectors, and even the very basic tuning tool of a S-afc damn near puts you at 1500 bucks......... think about it for a second



..............................

where as a 200 dollar cam, a 100 dollar header, a dremel with lots of bits, and a spare head, intake manifold and a 100 dollars worth of crap to start making an ITB setup gets you something worth 200hp N/A............. that type of setup is more about refining what you already have, if you can do the work yourself all it requires is your time..... where as with a turbo you have to buy shitloads of expensive parts just to get it running.......



edit.........
also the more I look at stuff, most cheaply put together very basic KA-T people are making 180-230whp.......... if you fail to realize that, then you don't look around at many KA-T projects....

[Hit_N_Run-player]

i have a reply, but its long and i typed it on my other computer at my other house and forgot to enter it, ill reply later lol

[Fla240sx]

lol I respect that, I like hearing other people's views....

[johnnyboy5]

I just like to go fast, turbo or n/a, and i like the turbo feeling better. But I'm with Fla240SX on this one. IMO i think having a N/A setup is great. Could be more dependable, cheaper, and you dont have to deal with smog issues in CA. In my situation, i would go with the N/A setup on my 240. Does a N/A setup wear the engine as much as a turbo? However, that doesn't mean I dont like turbo. Just my .02

See, i tig weld and fabricate. Me building a turbo setup (manifold, DP, intercooler piping, etc..) can be done for what cost of material is at my house. I also get free turbos (all IHI RHB/C series) so i dont have to pay for that also..) Fuel system i would have to pay for yes..

All im saying is, fabricating a turbo setup is much easier IMO, head work is some crafted shit. Not just anyone can get in there and dremel out an aluminum head, its not that easy, or atleast thats not how i do things.

Who said anything about 350whp? i said i would make 40whp more than your NA setup.. Ill say conservatively, from what we have seen done before, the most WHP you'll be making if you put loads of work into the head, crank, and block, that you'll get out 210-220whp (and thats me being nice).

You spend 1500$ on a KA, and ill spend 1500 on a KA, NA vs Turbo, guess who will make more power/cost...

I like N/A also, i just think its a waste into an S13 or S14. What someone needs to do it build an N/A ka and drop it into a datsun 510 or a 1st gen RX7 . The S13 and S14 would be underpowered with anything n/a but a V8.. thats why i argue it, not that im against the whole N/A KA24 idea...

[johnnyboy5]

that's ok, I got no money, LOL
