in need of opinions for my 240sx

[master6]

hey ppl of the 240SX forums! so im gonna get a gen 1 240sx from my moms boyfriend. (for free!!!) i need to replace the head gasket, and in the process, im gonna replace at least the valve gaskets and maybe a cold air intake setup. So, without turbo'ing, what else can i do in there to get the most power out of that engine?

on to turbo'ing, so according to this aritcle http://www.ka-t.org/forums/viewtopic.php?t=5597 i put together a list of parts to add a turbo. it is the "Average" section. tell me if this if good for the most part:

Turbo: http://store.max-redline.com/s...etail $188intercooler and BOV: http://store.max-redline.com/s...etail $478manifold: http://store.max-redline.com/s...etail $115Fuel reg: http://store.max-redline.com/s...etail $115injectors: http://treperformance.com/i-13....html $299.99SAFC-2 controller: http://www.essentialgears.com/....html $304.69MSD BTM: http://www.cimotorsports.net/m....html $279.99MAF: http://www.z1motorsports.com/p...=1830 $195

if there is anything else that i am missing, would be good or better feel free. ill have to get a work log put up once i get the car in my garage.

Well, one major part you don't have listed is the clutch I got an F1 brand stage 2 clutch off ebay for ..?? cheap (can't remember..) and bought a new oem flywheel to be on the safe side.

I'm not certain that with only an safc that you can tune for the injectors AND the z32 maf.. not sure, somebody else'll probably chime in though.

oh yeah, forgot:wastegateboost gaugefuel pumpdownpipe/midpipeturbo elbowcatback exhaustz32 fuel filter, perhapsmisc. fittings/hoses/whatnots

bleh, that's all I can think of at the moment

[master6]

well, no clutch cuz its an automatic lol. does that affect the turbo at all? and yeah i left all the little less expensive parts out, cuz it was too much clutter. but the main part was the current tune up stuffs, so no matter. also could i just get some general info on the car? like common breaks, easy fixes stuff like that.

[sainifabulous]

Hey i just installed that cluth how is it working out for you?i heard its a hit or miss. how many miles have you put on it?

[sainifabulous]

i heard some horrer stories if you turbo a car with a auto thats why im doing a 5speed swap i recommended you done one aswell.i dont know if its true but your auto transmission wont last as long if you turbo it

[gingerbredman]

I've probably put a little more than a 1000 miles on it so far. It's held up good in general, but I HAVE had some issues:

The throw-out bearing that came in the kit was smaller in diameter than the one I took out of the transmission, I hunted for one like mine and didn't luck up, so I used the F1 bearing. Since about 2 weeks now I notice the bearing is "growling" making that funny noise when you're about halfway engaged in a gear (like when I'm easing around a parking lot at near idle speed, slipping the clutch a little). But the functionality of the F1 throw out bearing seems to be on par with the original, despite the difference in size

The clutch initially slipped bad, but that was because of clutch pedal adjustment, I adjusted it to where it engages about 3" or so from the floor, been fine except for a couple of occasions. It hasn't happened in a while, but a couple of times when I went to ease from a red light, it would just slip, bad. If I let the idle come back down it would engage and I'd be on my way. Happened twice, and mind you I broke it in properly, I broke it in about a week lol. I have no clue what causes that but luckily no probs since. This was probably within the 2nd month of having the clutch in.

Recently, besides the light bearing noise, it's been doing great. My buddy has an sr redtop also with the same clutch (same brand, same stage) and I haven't heard him complain yet.

All in all I'm satisfied, knock on wood, cause I'm planning to boost pretty soon. Oh yeah btw does your pressure plate have "Exedy" stamped on it? I noticed it on mine..

OP my bad, I like to ramble, just trying to help all I can. Anywho, I notice you have a ka24e which honestly I don't have much experience with, other than that my buddy(with sr) had one and had nothing but problems, ignoring that fact I got my first single cam out of my bunch not too long ago.. fuel injectors started leaking, fixed the leaking and now it runs like a log truck

Common things in general are rust/corrosion, aged suspension parts (shocks/bushings), front crank oil seal leaking, ..jeewhiz im starvin, I'll check back up later man, in the meantime post some pics up if you can, eventually more folks will start coming to read your post and demand a pic of your ride!!

alright so if the recomended is to change to a 5 speed, then i will just save up and do that. what are some engines that fit in nicely? and to get back to my first question, what can i do to increase performance on the stock engine, other than replacing gaskets? ill check the spark plugs, but i dont know much else to do with out looking at the thing lol. it should be in my garage by this weekend if not before.

[sainifabulous]

You can upgrade the intake and get headers and exhaust that would be nice but other than i suggest you get a complete 5 speed swap like i did and get a dohc if you can or a sr would be nice if your gena do a swap anyways

[sainifabulous]

actualy i didnt really see a exedy stamp on mine but i got the 11 pound fly wheel combo, heard the clutch is good with that fly wheel comboi got done with the 5 speed swap but im running into electrical problems the car wont crank/turnover i keep hearing a click sound in the fuse box near the battery im guessing the lower wiring harness it came with is f**d or i put it on wrong or something

[gingerbredman]

Hmm, if you swapped out the harness from a manual also, then everything should plug up and play I would think. That clicking could be your ignition switch going bad. Mine started messing up on my old 240 and I would have to wiggle the key while trying to crank it, it would click and eventually it would start up. Now I've a different chassis altogether but the only thing different with the ign. system is the ign. switch and it cranks fine..but if it crunk up fine before then it shouldn't be the switch. It could be something else with car, get a buddy to turn the key while you hunt down the clicking noise, could be a bad relay somewhere.

Starting mods are pretty much just:intake systemheader, test pipe, cat-backunderdrive crank pulley redo some engine ground wiring with better wireelectric fans

of course you'll want to replace the distributor cap and rotor, plugs (Autolite Platinums from Wally World did fine for me), plug wires, fuel filter, tune-up stuff before you start getting into upgrades, a car in need of a tune-up responds poorly to mods.

I saved a few nickels by (at first) just removing my stock airbox and throwing a cone filter on, grabbing some extra amp wire I had to improve some grounds under the hood, and getting a pair of electric fans off 93-97 nissan altima (i think) for around 20 bucks at a U-pull it auto salvage yard.



Ebay and some other sites have cat-backs for around 150 starting out, I've heard 'this and that' with headers off of ebay, mostly fitment issues so search first and read up on people's experiences with different brands. I myself never got a header, never got a cat-back because every nut and stud on the exhaust system was rusted to hell and back, I figured I'd just leave it. I'm thinking about getting an ASP lightweight crank pulley next.

Engine-wise, you've got the ka24DE which uses the same block as the ka24e but has a different head of course, needless to say it drops right on in. The sr20det (s13,redtop,blacktop) drops right in also, but there's a little bit of wiring you'll have to do since it uses a new harness and ecu. I don't know of what other motor can just drop right in without modification to the motor mounts and driveshaft and such.. used ka24de's are pretty cheap but I mean really you don't know anything about the motor until you do a compression test. You could snatch a twin-cam up and leave it in the garage or wherever and build it up over time and prepare it for a turbo

what is the biggest that i can go with my exhaust using the stock engine?
