240SX stats...

[cougarZERO]

i've decided not to screw up my warranty on my cat my modding the tranny and throwin headers on and jsut invest in something in a 5spd RWD.... so that brought me to the 240SX or 300ZX. i'm tryin to get a non-turbo 300 but prolly will be in a 240 if they have serious 1/4 mile times so...

a) what is the average stock run for a 240?
b) how quick can i get it jsut by droppin a couple grand into suping it up? (header, intake, exhaust... crap like that)

thanx for any information guys

[LanceS13]

IMHO, the 240 is more at home on a road course or at a autoX than at the strip. This is because they run around 16 stock and maybe mid/high 14s after a couple grand, depending on what you do to it. The 240's forte is its handling.
stock specs:
155hp...getting about 138 of that to the ground
160ft-lbs
2700-2900lbs depending on year/trim level

Low 16's to high 15's stock. $2000 on non turbo go fast goodies? Atleast mid to high 14's. But the 240 is not only made for going fast in a straight line, it handles excellently too. You can make the 240 as fast as you want to spend! Turbo one street driven in texas is running [email protected] 131 on the factory KA motor with aftermarket pistons and rods.

[cougarZERO]

sounds sweet n all, but i got a wicked mo handlin car already, thats why i lov emy cat so much it'll frickin hug a turn like a mofo... i wanna get a car i can make beat or at least hang with GT's and comaro-birds... i'm thinkin a 1990ish 300ZX is the way to go but if i can't for insurance reasons i'll get a 240...unless the insurance is bad for them too... but i figure i can drop 5 grand on a 300 and have the performance it'd take for a 2 grand 240 with 3 grand dropped into it with the whole wide body thing happenin... i dig 300's hehe

[LanceS13]

I can't say for sure b/c I've never driven a Cougar before, but I'm willing to bet that the 240 will outhandle it.  That's considering the Cougar is fwd, nose heavy, and about 100-150lbs. heavier.  The 300ZX is definitely a better performer, but it's also more expensive and has higher insurance.  I'm thinking about 50 additional horsies on the 240 will put it in GT (260hp/3240lbs.) territory.  That can be done with either a nice NA setup or a SR20DET motor swap.

[cougarZERO]

if i get one i wanna mod the existing engine, waht can be done with that?

what will these do?

header
CAI intake
exhaust
pulley
short throw shifter
racing clutch

[Jeff240sx]

prolly about 20 (conservative) to 25 hp.  Those aren't really power mods that the 240sx need.  It needs to breath.  Drop the pulley, as that is an exceleration thing, along with the clutch, as I haven't heard many problems with that.  Spend that cast on a good head porting, and port/polish intake manifold.  
Then decide on if you're gonna go turbo or stay NA.  A turbo with "breather mods" will gain you SO much power.  $3k kits alone claim 240hp, and with the porting and exhaust, you should be up at least 255.  
So think.. The cash you save from buying a $12k 300zx into a $8k 240sx will net you 255hp.  25hp less than the "big brother," yet 600+ pounds lighter.  And then you'll save insurance cash, plus around 8 mpg better.
-Jeff

[LanceS13]

That would probably put you in Integra GS-R...mid/low 15's.  Jeff seems to be on the right track with the turbo...however, check the links section of this sight and you'll find a link featuring a 230hp NA 240SX.  So it can be done either way.  It just depends on how much time and money you want to spend on it.

[cougarZERO]

ok as an example i want it to hang with or beat a rustang GT or comarobird or whatever... i wanna make this 4 banger sound like a big bad v8 (like the turbocharged SVO mustang which is also a 2.4L I4) i know stuff about the cougar but its fairly obvious a I4, mtx, RWD is new to me... what do i have to do to run around 13ish?

oh and drive a coug dude, say anything ya want about it man, be it slow ugly or whatever, but it'll handle like a mofo <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/wink.gif" border="0" valign="absmiddle" alt=';)'>

[Jeff240sx]

Well.. a new Mustang GT has. don't quote me, 285 hp. &nbsp;95's have 225. &nbsp;Anyway. &nbsp;They are heavy as ####! &nbsp;With either NA power or turbo power, you're 240ish hp will stomp a mustang. &nbsp;I dunno what the #### a comarobird is. &nbsp;A CAMERO has 320hp with the LT-4 motor for the z-28. &nbsp;As does a FIREBIRD. &nbsp;Those are significantly heavier than a 240sx, but have a lot more power. &nbsp;To run 13's, you almost need a turbo, or a LOT of tuning on an NA. &nbsp;I think stock 240's with a turbo run 14's. &nbsp;With some other mods, you'll hit the 13 mark.
And yes, cougars are sloooooow. &nbsp;And I DONT CARE WHAT YOU SAY, A RWD CAR WILL OUTHANDLE *most* OTHER FWD CARS!!!
-Jeff

[kitoro]

agreed agreed!
^.^
the only fwd cars that i heard have been really GOOD on the track are the ITR and the Sentra SERs... those have been tuned for it.

FWD have a problem of understeering... plus they're no fun to drive as opposed to RWD sliding!!

[cougarZERO]

yeah thats the thing with RWD the rail slides, i like the stability of FWD n all its kewl for autocross, but RWD is frickin fun i u to play with my dads truck on backroads... a big f150 and a couple dirt roads is pretty fun

[cougarZERO]

ok i'm very close to making a decision, the insurance will most likely be the deciding factor... ok i got one more question

what can it do if i do thsi stuff?

port polishing the upper and lower manifolds (or whatever the I4 has)
engine blueprint to replace worn parts and strengthen the weak ones
racing clutch
bigger MAF
CAI
exhaust
short throw shifter
pulley
lightweight flywheel &amp;/or cam gear

anything else? excluding a turbo, and NOS would be the absolute last mod

[Jeff240sx]

First, let me express my distaste to topics that start with &quot;How much hp will I get if I do this?&quot; &nbsp;And you, sir, have 3 of them. &nbsp;Then the &quot;What do I have to do to run this time in teh 1/4?&quot; &nbsp;And then I HATE posts I can't read because they are typed in ebonics, and think they are cool. &nbsp;And we all posted about 240sx owners bieng a little bit higher class than the rest. &nbsp;I'd be ashamed if cougar gets a 240!
Now... to your pitifully worded question... &quot;What can it do if i do thsi stuff?&quot;
Engine blueprinting. &nbsp;Boo. &nbsp;Are you THAT rich?!? &nbsp;It's almost useless on a low power NA engine.
Racing clutch. &nbsp;Are you still on this? &nbsp;You won't make enough power to fudge your old one.
Bigger MAF. &nbsp;I thought this would be helpful, but it's only necessary when you go turbo.
Pully. &nbsp;I don't like them, but you might gain some speed, and not power.
Lightweight flywheel. &nbsp;Speed. &nbsp;Not power.
Cam Gears. &nbsp;We don't have them.
Short shifter. &nbsp;Speed. &nbsp;No power.
So you polished and ported the manifolds, with an intake and exhaust. &nbsp;175-180hp is my somewhat educated guess. &nbsp;3-6 for the CAI, 5-10 for the exhaust. &nbsp;Honestly dunno about the polishing. &nbsp;couldn't be worth 9 alone though.
Sorry for trashing you before. &nbsp;Just type normal. &nbsp;You might get some other people to reply. &nbsp;And ask more educated questions. &nbsp;Not &quot;How much power.&quot; &nbsp;but along the lines of &quot;What mod combinations would I need to hit 200 NA rwhp.&quot; &nbsp;Then you don't sound like a moron.
-Jeff

[cougarZERO]

ok listen, i don't know jack smack about 240's or 4 bangers in general. and ebonics?! i type the way i talk, theres no need to reform my speach structure for some people that for all i know are super intelligent monkies sitting around a big table on the net all day. and what is &quot;i'd be ashamed if a cougar gets a 240!&quot; sposed to mean? oh and if you can't read what i type you need to go back to grammer skewl bud <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/wink.gif" border="0" valign="absmiddle" alt=';)'>. i came on here with an inquisitive open mind and respected everybody then you had to go and bug me. i could call you a pathetic hipcrite for your improper use of english or slang and crappy punctuation but i'm not an arrogant prick like you. almost every post on here is at a very late hour so please for give the typos your majesty. i didn't know it was so politically correct here...
man i might get a 300 just so i never see you type again...
sorry for the flame folx i get kinda carried away sometimes

&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;-ZERO™

[LanceS13]

Ok...I'll make some suggestions...
-high compression pistons
-racing cams
-honed intake manifold
-port and polish
-bored out throttle body
-intake/header/cat-back exhaust
-gutted/hi-flow cat
-a lighter underdrive pully will free up a little power by lowering parasitic loss, but some say it will harm your engine in the long run b/c of it's lack of a harmonic balancer
-a lighter flywheel will also lower parasitic loss, as well as increase throttle response

If tuned right, it's probably fairly feasible for this setup to push 210+hp to the ground...but your also looking at over $3K.

[Jeff240sx]

Ok. &nbsp;I really didn't mean to start a war. &nbsp;I just wanted to point out that your posts were hard to read. &nbsp;No capitalization, and the stange wording in your posts, like, &quot;sounds sweet n all, but i got a wicked mo handlin car already, thats why i lov emy cat so much it'll frickin hug a turn like a mofo&quot; &nbsp;I read this post about 4 times to get what you were saying. &nbsp;And, I personally never attacked YOU specifically. &nbsp;And I get a &quot;i could call you a pathetic hipcrite for your improper use of english or slang and crappy punctuation but i'm not an arrogant prick like you. &quot;
What improper use of english? &nbsp;What slang? &nbsp;And what punctuation errors? &nbsp;Spelling errors, sure, I type 75 wpm with some switched letters. &nbsp;
So, like I said. &nbsp;I never attacked you personally, and answered your question, and gave you advice. &nbsp;You should be appreciative. &nbsp;But here's more advice.
Don't gut out your cat. &nbsp;You will have a bad smell. &nbsp;I can't remember which one, but it's either rotten eggs or tractor. &nbsp;I think it is the rotten egg smell from a gutted cat. &nbsp;
Also, a pully is considered bad. &nbsp;Read up on it at 240sx.org. &nbsp;There is much there about the crankshaft wobbling from the lack of a harmonic balancer. &nbsp;That is bad.
And I really think that if you push 210 hp, you should do something with your fuel system.
-Jeff

[LanceS13]

It wouldn't hurt to upgrade the pump and injectors, but I don't think it would be absolutely necessary.
And, yeah, gutting the cat is kinda bad b/c of the smell and b/c of all the stuff you're putting in the air...but a hi-flow cat should be good.

[cougarZERO]

jeff- its alright i can relate to being cranky late a night. see i figure if i can score a 240SX mtx in good conditition for about $3000, drop $3000 into engine work, and have 210 horses pushin a 2700 pound car, i'd have one fast car. thanks for the help guys, and if the handling is as great as you say it is i'll crap myself. i hate cars that are fast but drive like boats.

there are a few shops in the houston area that i'm sure can do the work you're speaking of, but can i get a nice healthy dual exhaust setup? or will that decrease backpressure resulting in worse performance?

[LanceS13]

A'PEXi makes the N1 dual, but both tips come out on the left side...not one on each side like the typical dual setup. &nbsp;I would suggest a proven single exhaust like the A'PEXi N1 single or the 5Zigen Fireball. &nbsp;And when shopping for a 240, get a '91+ model. &nbsp;The '89/'90 models had timing chain issues and they were also SOHC's with about 15 less hp.

[Jeff240sx]

Cougar. &nbsp;
Decreasing backpressure usually results in less torque, but more horsepower. &nbsp;There are generally 2 size exhausts that would work in our 240sx's. &nbsp;For a NA setup, plan on buying about a 2.25 to 2.5 inch exhaust. &nbsp;And for a turbo setup, or if you know you are gonna go turbo, go for the 3&quot;. &nbsp;Also, dual exhaust doesn't exist on our cars to my knowledge. &nbsp;There are dual tipped mufflers, like Lance mentioned, and A'PEXi makes a great exhaust, as does 5Zigen. &nbsp;Also, a true dual ehxaust does not exist, as true dual exhaust needs 2 cylinder banks to run 2 separate pipes. &nbsp;We have 1 bank.
Any other questions, just post.
-Jeff

[LanceS13]

Actually the A'PEXi Dual splits at the cat and has two small canister mufflers. It's not just a dual tip muffler.

Torque comes from high gas velocity. &nbsp;The thinner the pipe, the faster a certain amount of gas has to travel to get through it. &nbsp;However, as RPM's rise, more and more air is being processed. &nbsp;At high RPM, the ability to move as much air as possible becomes more important...so a bigger piping is needed. &nbsp;The trick is to find the best compromise. &nbsp;I would say 2.5&quot; is optimum for NA, but I'm running 3&quot; simply b/c I'm satisfied with the 240's low end torque but wanted as much top end power as possible.

[Jeff240sx]

Damnit. I knew that! I'm just not thinking right now. It splits into 2 120mm pipes.

-Jeff

[cougarZERO]

the dual setup on my coug is just one muffler branching into two pipes, its not really a true dual. i guess if you wanna be technical it wouldn't help performance at all. maybe i just like symetry. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/wink.gif" border="0" valign="absmiddle" alt=';)'> anyways thats what i ment when i said dual exhaust.

oh and i found a 240 in good shape, lemme know what you think...

[LanceS13]

Looks nice. &nbsp;I'm not a huge fan of the coupe body style...but it still looks nice.;)

[Jeff240sx]

Yeah. &nbsp;It looks nice body wise, and has low mileage, but for a somewhat high price for a '91 IMHO. &nbsp;Also, the coupe body style in the s13 is not good for a system. &nbsp;Neither is my '96 coupe <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/sad.gif" border="0" valign="absmiddle" alt=':('> .
But... low mileage, and nice looking car.
-Jeff

[cougarZERO]

by &quot;system&quot; do you mean stereo system or an engine or sumthin? i don't really care much about systems. i'm gonna try and talk the dealer into droppin the price to $4000, but it does have a nice body and low milage so i won't hassle em too much...

[LanceS13]

If you plan to autox it, the coupe does have a slightly stiffer chassis and is slightly lighter...so it does have it's advantages. &nbsp;I hope you enjoy it as much as I've enjoyed mine!:biggrin:

[cougarZERO]

I just wanna be able to put up a fight for my bud's 5.0 &nbsp;or at least not get wasted. i'm tryin to get a hold of a guy thats selling a 300ZX TT for $6600... &nbsp;that'd be real nice

[ca18guy]

A 300ZXTT for $6600 will cost you a foot and a leg in repairs, unless he took incredable care of it (for $6600 i HIGHLY doubt it) i would'nt buy it unless you you have the money to repair it. Anyway if you want to compete with the 5.0 then get the cheapest S13 you can find and swap a SR20DET or CA18DET.

P.S. I can't stand seeing some of the people that buy these cheap 300ZXTT's then drive em in the ground and wonder what happened, I only hope when i get back to the states there is a 300ZXTT left in good shape....sorry for the rant i get emotional over Z's <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>

[cougarZERO]

i'll check it out before i buy it, if i even can buy it of course. he says he took real good care of it, it jsut had a major tuneup timing belt and timing belt tensioner jsut replaced plus some other stuff. it looks like its in good shape and i bet he was into performance so he prolly took care of it. idunno i'll prolly fined out sooner or later
