lol i hope 2 pages worth of "don't do suicide doors" talked you out of it. focus on one thing at a time. make a 5 speed swap the first thing on your list after a good tune up and check for leaks. then worry about performance adding parts.

Your engine seems to have a leak of some sort.

With suicide doors you'll be doing exactly that...suicide.

I originally didnt think about doing a 5 speed switch but then again i still have not etched in stone that im not going to do a LS1 tradeout. Im trying to decide really if i want a v-8 engine in a light car or not, I dont think it would be as good on gas as the 4banger would be.

I really dont have a drawn out p[lan yet, but mpore than likely Ill keep the ka engine and rebuild it and the transmission. Ive had alot of manual trans in my other cars and with my stop and go driving here it kills them pretty quickly...

YES IM A NOOB deal with it...

as for the engine, Cylinder 4 is knocking which means either the crank is gone or the bearings are shot, but I wont know until i get the engine out and dismantled.

Only if you have a very good welder, and even then its not the greatest solution.

Turbo the ka engine with a msd ignitiongo for a vader 2 body kit, and wide fenders.some new mirrors, with marker lights, blue for show and yellow to stay legal of course....some LED clear tails.turbo kit with an intercooler. havent decided on turbo controller yet or what kit i will get.i have two choices on headlights either convert to diamond back or go for a dual halo replacment... kinda thinkin to keep traditional and go with diamond conversion and get a droopy eye kit.New catback kit with downpipe test pip and muffler. silencer optional... carbon hood, carbon hatchback, carbon headlight covers and if i can find some, carbon doors to replace the heavy steel i have now..As for a wing door, not decided yet. I might go offbase with suicide doors for a lowrider look.

wheels no idea yet, specifics on pistons or rods or intake, no ideas yet but have lots of choices.
This looks like a list I would have made the night Fast and the Furious came out.

You want a V8 in a light car, yet think you need carbon fiber doors to reduce weight? Then suicide your CF doors?

I think you should fix your 240sx to running great first, unless you are swapping it right away. Then do cosmetic stuff, don't make a good shell ugly and then quit.

Well like ia said this is a really long build, as for the Engine, Cylinder 4 is knocking, so i have to rebuild the engine and replace the crank bearings and rods, so might as well, go and get the engine bored over and update the innerds.

Ive narrowed it down to crower rods and je pistons for the low end. As for the top end, Im looking at stage 2 cams. an Excessive intake manifold and a 90mm q45 throttle body... thats a start...

NOS is an idea though... ill probably end up using it to cool the intercooler

what compression are you aiming for? What is your horsepower goal?

You think it is necessary to overbore? Do you know benefits/ drawbacks?

You seem to type a ton of project ideas and things that would take real skill to accomplish, I am trying to ground you a bit so you don't drift off and fail this car, spend lots of money in uninstalled parts before being sold off to someone else in an attempt to recover even 60% of cash put in.

Just trying to help.

well thats why i started this thread is to get ideas and to LEARN>.

i know i want to turbo with a T3 as for cmpression, I dont want to go overboard i want power but not overkill, this is gonna ba a daily driver for me...

so any advised would be great....

like i said with the engine, cylinder 4 is knocking when ran. I dont know the extent of the damge yet, but i know i have to replace the piston rod and crank, might as well do em all since im gonna be in there already right???

the only rods i can find at a descent price are the crowers, the pistons im seeing like 3 choices, and crower does have some top end items, valves, springs, and cams, and in looking there i see 2 different options stage 2 nd stage 3, i know stage 3 would take chaning the bottom end alot so i thought just getting the stage 2 to get some better intake and exhaust. thoughts???

Just gonna throw this out there... have you ever built a motor? I would so you haven't just by your posts.

I would suggest a KA24de + 5spd swap and drive on it for a bit. Then you have the other motor out that you can build on the side. When it is ready swap it in.

You just seem to know what you like, but not what you want.

if you want a decently nice well built motor, do this. have your block hot tanked, bored and honed. throw some rods, whether they be bc, ams/turbo240, eagle, etc. get some pistons (i recommend about 8.8:1 if going turbo) arias makes some good ones, along with other companies you'll find as well. get arp studs all around. have your head port and polished with atleast a 3 angle valve job. let it breathe better with some camshafts, the v2 BC ones you talked about are pretty good, ams offers others, search around. maybe get new valve springs/retainers. get some bigger injectors, above 550cc preferably top feed maybe 72lb . walbro pump, bigger fuel filter, mafs or change over to map sensor. get a t3/t4 setup with an external wastegate, 3" turbo back exhaust. Xcessive intake manifold (or itb's would be sick) with maybe a q45 TB, some underdrive pulleys (crank and TB) and then either a good ecu tune from jwt or enthalpy, or a full standalone system would be even better. then dont forget about a good flywheel, stainless steel lines, one piece driveshaft, and a good lsd. then theres the ignition system. i personally have the msd sci-l w/ blaster 2 coil pack, but nowadays you can get the msd 6A with blaster3. def get one with a two step system.

lol there you go, i just built your car for you. have fun.

or maybe a nice responsive machine. try the 2.65L stroker kit, with forged 11:1 compression bottom end and fully counterweighted crank, v3 camshafts with built valvetrain, itb setup, full standalone system, bigger injectors, pump, filters, etc, and a nice ignition system along with a bigger TB and smaller pulleys. add electric fans to both and delete emissions a/c and anything else on the rotating assembly that just wastes power. that'd be fun as well

dude, since you don't know 240s i'd like to know more about this knock b4 you dive into something and overkill with the repairs. tell me more about the signs and symptoms and don't assume its blown. these cars suffer from timing chain sounds or lifters. there's alot of threads about this and their repairs. if you do it yourself you could fix this problem with about 200 or less iirc.

that being said, do you plan to drift or go str8 lined?Think about suspension and brakes as the first move if it is just the lifters or chain.

I also want to say you have my upmost respect for comming back and side stepping the bashing....it's sort of like a nico pledging process or initiation

yeah,

Its the same sound my mercury had before the rod went out the dside of the engine block.

The knock starts load with the lifter sound but then the oil hits it and the lifter sounds go away, but the knock is still there, and the only cylinder its hitting on is the last cylinder on the block the one closest to the dash.

Im not worried to much about over kill because im rebuilding the engine anyways...

and i wont start buying until the engine is out and disassembled. then i can verify the piston hitting the head..

Ill take some good pics while im doing it so you guys can see my troubles and can help there too...

My dads c5 gets better gas milage then me. actually. but yeah dont do a v8 swap, because with gullwing door, clear euro tails, and a poorly installed ls1, you will get made fun of.

yeah it increases with higher rpms and when you put your finger on the spark plug tap on top, you can feel it but only on the 4th cylinder.

your piston is what sets the compression.

link to the main BC ka page, read up on the camshafts, its very detailed. if you go with v3, you'll have to do the valvetrain, v2 you shouldnt have to.

as far as the stroker kit i was talking about, it's on that page too. it comes with pistons/rods. it also says you can choose what compression you want. the few people ive seen do this so far, have done it at 10.5:1 but if you go the route of all motor, i'd go a lil higher, since 11:1 should be fine on 93 octane and a good tune, but no higher or you'll need better gas. but i would still definately see what BC recommends and do some searching on compression vs. octane on these motors. there might not be a lot of info out there, but theres some

dude, nice car for $500. Does it have rust? I know around here it is very hard to find good looking 240s without rust. I think the suicide doors would look.... out of place and would be awkward to open too. but that's my opinion I'm not going to be uptight and tell you what to do with your own car. As far as cosmetics go the car is so good looking already all I think they need is a good drop, some nice wheels and a body kit, but nothing over the top and ridiculous you'll just end up tearing it up on a speed bump or something anyways.

Good luck with your project

A change to five speed in my opinion would be sweet, so it can actually feel like you're driving.... a car and not a boat. But I would just fix that one up and trade for a five speed.

A V8 would be death for your gas mileage. Stick to the 4stroke they sound better anyways
