Engine blew dad says something I dont really believe...

[unrealskills]

Well last year my dad bought a 1994 Nissan 240sx but he found out that the engine was screwed because the guy who isntalled the injen tech Air Intake System was according to my dad too much for the motor also it had a injen tech muffler and blew the pistons and i think it had a turbo not sure and it's a automatic. So he said it would cost him 4 grand to get a new engine. So I was wondering what could have been the scenerio for the engine going crap'o on me?

I asked him if i could keep it (i luv 240's and he was about to sell the parts) and he said yea. So now it is now in a warehouse with the other cars just waiting for me to go to the Daytona Speed Way and just race!

94?

Was it a convertible? If not, then it isn't a 94.

I doubt the intake or muffler had anything to do with its death, and it's unlikely that it was turbocharged.

A KA24DE engine (which is what your car has) is FAR less than $4 grand. You can find those in junkyards all day long for $300-$1000.

let me ask my dad right now its been a long time to check out my baby (hurricane and school and work lol)

[unrealskills]

sorry for the confusion (dumb me kinda rusty on my car savvyness) but the car is a 1993 Nissan 240sx with turbo and the pistons were screwed not the entire engine and the turbo is bad but not screwed.

[InsanityInc]

It has a turbo? Is it a KA or an SR?

[unrealskills]

not sure might have to check on saturday while i go out is SR the model on the engine?

How could someone be so clueless about their car? If you don't even know what kind of motor is in your car, you shouldn't be allowed to drive it. But thats just my opinion

[unrealskills]

the thing is that i dont even have my license and its been almost 3 months since i have seen the car (had things in my life that had to be done) so i forgot everything and i am 14.

you're a bit young, I could be your daddy...

anyways, intake/exhaust isn't going to do that to your motor, it's probbaly abused somewhere along the way.

A KA + transmission would cost aorund 300~500 in socal. Some sucker bought mine for 600$ but that's only because it was in a very clean condition with very good compression.

Install is another story, some shop charge 700 for labor while another could charge 2000... maybe that was the case.

good luck with your car

[unrealskills]

thats what my dad said but could i just change the piston rings and pistons and remove the turbo and have the car running?

[Fenvy]

when I talk about the labor being from 700 to 2000.. the 2000 is overcharging. Popular KA to SR swap including troublkeshooting and wiring service cost about 1500 at reputable shops. My local mechanic would do it for 1000$. But again, this is strikly KA to SR... meaning that KA to KA shoudl be cheaper! I woud say that reasonable price is 500~750. don't pay anything beyond that.

how the hell did the car get turboed in the first place? sounds like everything is already there... such as the plumbing, turbo manifold.... etc

I perosnally would just have the engine rebuilt

just supply them the nessassry valvetrin parts and you are ready to roll again and this time with a fully built/reliable internal...

why did I say supply them with the nessassry parts? because you can get better parts online at cheaper the cost. I think fiznat has a list of what he did to his motor somewhere on this forum. do a seardch on his username

[babowc]

if you give us a detailed pic of the engine bay, we'd be able to say what motor and if it indeed does have a turbo system on it..

im not trying to disrespect an older person, but does your dad know what hes talking about?

[AZhitman]

Yeah, let's start over. I have a 14 year old son, so let's keep it on his level.

First, take a picture under the hood. We'll show you how to post it here, or you can email it to me and I'll do it.

We can go from there.

NICOnauts, let's get this young man some KNOWLEDGE!

[babowc]

another good idea would be..since you're only 14.. [not saying 14 is young] but at 14, there are alot better things to do than fix cars, like go out and stuff.. anyways.

if you could manage some time online or can get your hands on a nissan FSM. [not the online pdf files, but a book] you can learn a bunch.

i learned about most everything i know from here and minimal things from other sites.

a pic of your bay would be soooooo good, you know what they say, a picture is worth a thousand words.

Well, if the KA24DE engine in the 1993 240SX is a naturally aspirated engine (not turbocharged). It has a sorta light gold colored valve cover (the part where the oil filler cap and spark plug wires are).

An SR20DET engine is turbocharged and will have either a red or black valve cover. This engine did *not* come in any 240SX's sold in the US. If that's the engine you have, it was swapped in at some point.

That should make ID'ing the engine fairly easy.

Well, someone could have had a stroke of brilliance and turbo'd their ka ...but then turned 180 on the intelligence, not done it correctly, then sold it. Welcome to The Great Nissan 4-Cylinder Engine Debate! (argument).

The ka24de is basically a bored and stroked version of the Japanese engine, with an iron block instead of aluminum to deal with the thinner cylinder walls, higher compression ratio 9.5:1 vs. 8.5:1 (I THINK) for the sr20det, and a few other minor details... If you dont know what that means ask your dad or the Google. If the bottom part of your engine block is cast iron you have a ka24de (if you replace the pistons, make sure you use some that give you lower compression than stock if you have a turbo ka). If the lower half is aluminum, you have an sr20det from Japan. This is considered "cool" and it is also a very good engine like the ka.

Edit: It could be a ca18det also, or a six cylinder (from a Skyline or Z), but those are unlikely to be sold without someone mentioning it and making a big deal about it. Come to think of it, that's true of the sr20det a well. You probably have a ka.
