project n/a 240sx

[ztunelover]

oh no i dont need to bother with them with street races. slapping them silly over the local autocross course and 1/4 mile is so much more satisfying.

[rob912]

for the ITB setup your going to need a mega squirt system. Im going to rebuild my ka with ITB's and throw it in a 240z

[rob912]

plus how bad a** is this

You'll probably make like 135 whp with that. To get a good amount of na power you'd probably be best off going high compression.

lol, a fresh KA pretty much makes that stock.

I have JWT cams, ECU tune, P/P head, cold air intake, header, 3" Apexi N1 with testpipe, aluminum flywheel and I made 168whp.

I still have yet to put in my altima fans.

[ztunelover]

which headers did you use?

i know this might sound stupid but i love the lower pitch rumble and growl the cats have than the high pitched sound of the test pipe. so i would like to keep the cat. the dc unit deletes it. and i personally dont like how it sounds.

and i already ordered nistune so i doubt ill use anything else. ill see if the ITB thing works with it. if so yay if not oh well. upgraded tb + custom cai with relocated battery would work well too.

[asoomal]

im getting a hyper ground system they are giving off a bunch for half price. definitely getting those.

but im never going with anything other than fluid dampers like the ati super damper.

and quick question. does the hotshot headers delete the cat like the dc sports unit?

Hotshot still exists?

[glitched]

The KA isnt a motor worth worrying about dampening.If you just get a lightweight crank pulley and years down the line something does go- then you have an excuse to rebuild the motor for more power or swap something else in. Or even just pickup another cheap KA.

and I still believe in getting as much power to the ground because we are talking about small numbers with a NA KA.

Track down some rare underdrive accessory pulley's, crank pulley, switching to electrical fans gets rid of hte mechanical fan weight as well. Lightweight fly wheel, aluminum drive shaft( I love mine), and some light weight wheels. after driving with these mods, driving another 240 even with I/H/E would feel lethargic.

while your at it, start going with overall weight reductions as well.

Before every season i do a full tune up as well, Red line synthetic oil everywhere, motor, trans, and diff. new cap/rotor/plugs/wires, new z32 fuel filter. Clean the MAF sensor, properly re-oil the K&N (with another cleaning of the maf midway through the season incase any K&N oil gets on it) new TPS even.

If you want to actually compete at an autocross, you need to worry about tires and experience first.

[ztunelover]

well the ati unit is about 80 bucks more than the unorthodox unit right now. so i dont see any reason to not get them. and the unorthodox unit is not that much lighter either. the a/c and p/s im going to try and get some underdrive into them, the abs system goes. thats gotta save a few pounds. i know there will be a cf hood, trunk, and a roof from kognition design eventually,

the driveshaft would be the mazworx carbon fibre unit. the flyheel would be either fidanza or nismo. clutch i dunno. the rims the nismo lm-gt4 just because they are plain sexy. z32 uprights, no back seat + battery relocation means good amount of front to back weight balance maintained. Once the battery is relocated im doing a custom cai to make smaller tubing for lighter weight. plus some nice little mods.

The JIC magic coilovers are lighter tha stock as well so im thinking those. and lastly for the suspension the complete nismo link set.

obviously there will be more as i think them up, like steering wheel and little things that by numbers arent supposed to make the car faster but im sure it will feel better.

now that i think about it. the ITBs will be there for sure because i want to practice tuning ITBs before my rb is complete, cuz that would a very expensive motor to rebuild. this would not

[glitched]

I'm not very familiar with ITB, but how does a CAI work with ITB

[projekt_sx]

dude all you need to be hitting 14s on a quarter mile is intake headers exhaust msd ignition, a modified driver(a good one) and slicks maybe with street tires you would hit 15s. trust me i know alot of tricks with the single cams. or if its a twin cam you should be hitting 14 with just intake, a flowmaster exhaust, and msd ignition. where im from i have seen all types of n/a 240sxs and all n/a set ups. the badest ka set up i seen is hitting 11sec with nitrous on a quarter mile. i dont know how much horse power we pushing cuz we dont got a dyno here but we do have a drag strip and we do the times:dthumb

[ztunelover]

manifold on top of ITB cai connected to manifold maf connected to cai. look at the formula nippon or any of those type of formula cars you will see what i mean. i mean the rb26 has ITB with that stuff on.

[ztunelover]

dam thats pretty fast. il see about quarter mile later but i mean lighter suspension will mean faster accel too right? im looking to improve the car in everyway. straight line, turns, high speed stability.

you do know what NA means right?

great grammar btw

[projekt_sx]

oh yeah dude honestly i think its the driver that makes the difference. with my single cam i speed shift at 7grand. with suspension just get tein drift specs, front and rear strut bars (could be a no brand. dont really matter), and sway bars. those are good for drag and drift. theres alot of none believers on this forum about my single cam and the other 11sec single cam here. lol i just need time to take pics of the 11 sec car and ill post the thread soon

what do you really think suspension wise you are going to save weight on?

considering at best a light weight driveshaft is maybe 30 pounds in savings?

with suspension I would even take a weight gain, if it meant that it improved areo....... its not like 5 to 10 pounds here and there is really anything to note.

I can save more weight just running an 1/8th tank of gas instead of a 1/4

btw, most run a MAP sensor with ITBS and dont have a manifold or intake system......... as it is just more waste anyway.

[projekt_sx]

okay sorry about my grammar. its only like that because its just a stupid thread idiot i dont care. its not like im writting a college paper! and na means naturally aspirated.

[projekt_sx]

and if you want your axles to move faster get an aluminum drive shaft.

[ztunelover]

the z32 uprights are 16 pounds lighter the coils if i go jic would be roughly 5 pounds each front 3 pounds each back. the entire nismo suspension link is about 10-12 lbs lighter. the rims would be lighter for sure, the driveshaft is cf so im positive that thing would be a featherweight. how much does the stock 2 piece weigh anyways? 20lbs? cuz i know the cf units are 8 or 9lbs. unsprung weight really helps around turns.

[ztunelover]

the cf stuff is lighter than aluminum. i already made up my mind about this.

[heartofaskyline]

d where im from i have seen all types of n/a 240sxs and all n/a set ups. the badest ka set up i seen is hitting 11sec with nitrous on a quarter mile. Modified by projekt_sx at 1:33 PM 2/20/2009

umm... nitrous means your motor no longer qualifies as a N/A motor

[ztunelover]

net total im conservatively estimating the entire thng while being stronger and lighter would give me unsprung weight loss of 40lbs. doesnt sound like much but im pretty sure that makes a hell of a lot of difference while launching and even more importantly transitional response of the car around the twisties. trust me the stuff thats going in is stronger than the factory pieces. they just happen to be lighter as well.

And about the ITB. If im running MAP i think it would need to be a stand alone unit. Im not putting that much into this motor. Im putting ITBs in the first place to get some experience setting them up physically. As i repeatedly said before the ka is the test mule for me to learn on before i finish building and start tuning my n1 rb26dett. which if i didnt mention would be so expensive i probably need a mortgae it and still sell a kidney. that would not be good idea to practice on the ITB on that. it would be rather idiotic if you ask me. rather a 500dollar ka24 is a good motor to practice on.

[projekt_sx]

umm... nitrous means your motor no longer qualifies as a N/A motor

first of all i didnt say that the 11sec car was na

[rob912]

are you going to run straigt ITB's or put a intake plenium over them? If your going to run straight ITB's should go with a msd btm

[ztunelover]

put a plenum and a cai on the plenum. thats gonna allow me to draw cooler air in granted i get the ducting right. hell ferraris and lambos have been doing that for the past god knows how many years. actually the easiest car to find my setup is the e46 m3. ITB plenum plus cai.

[White Comet]

and if you want your axles to move faster get an aluminum drive shaft.

thats weird, if i want my axles to move faster i put my foot on the skinny pedal.

[hbpignosePA]

hell i put a rock down there.... my KA definately revvs to like 9k so its all good

id go w an aluminum driveshaft.

search zilvia and nico archives for ITB setups on KAs

[ztunelover]

i am researching my options right now.

[thematz]

Importtuner had a recent power pages of a S13. All they bolted on was a dcsports header, aem intake, and a 5zigen exhaust and they made 148whp.

[ztunelover]

well when i get around to dynoying the baseline numbers ill let everyone know...unless its embarrassingly low.

[thematz]

It will all depend on the condition of your motor. I've seen stock ka's dyno as low as 79whp and up 130whp if not a little more. Let us know how it goes. Good luck.
