I have a 95 240sx with only a Stillen Forced Air on it. I want to put a turbo on it but I would like to know what I need to get aside from the turbo to upgrade. Like do I need a fuel management system, new piping, etc... Please help me out because I found a great deal on a turbine and a manifold, but I need to know what else I need so I don't blow up my engine. My engine is the stock 240sx engine not the jap. version. PLEASE HELP!

 

you can run it stock at like 5-7psi with a fuel pump, injectors, manifold, turbo, and intercooler (all piping, bov, etc), and some sort of fuel management, IE standalone or if JWT offers a program.....

but if you dont know what you need, then you might want to hold off for a while....

a smart thing would be to build the motor first.

 

Well thanks for your imput but what I was looking for were some steps if I can run iti stock with just the turbo and the manifold. I am pretty sure that I can't but I was basically looking for a list of parts and like you said, what would need to be done to build the motor. If it is going to cost me 4300 or more then I am just going to get the S14 turbo engine with 25K. This place right near me will send one to me for 3800 and a tech I know will swap for 500. But hell I am 17 and I don't have that kind of income. I really wish I did, because I love turbos.

 

well i guess you could slap on a turbo, manifold, and a nice Front Mount intercooler, and some sort of Tuned ECU (jwt possibly), and run low boost...but you will be running the chance of blowing up with the high compression setup the KA has.....a lot of guys do the cheap ka turbo setups, blow up, then have to do it all again the right way for reliablity...

do it right, or do it twice...

ya know?

 

The reason guys blow up the stock KA is usually because they end up running a band-aid fuel system and end up detonating (lol, expect me to be one of those people... my fuel system is so much worse than a band-aid). That said, the KA's compression isn't exactly high compression. We're actually pretty lucky as it could be even higher (although... squeezing out a few more HP in stock form could have been nice).

If you really want to know what you need to turbocharge, a good bet is to by a book called "Maximum Boost" by Corky Bell (you can buy it here ). Read that front to back and you'll probably end up telling other people what they need or don't need for a turbo setup.

 

What do you think this would cost me all and all? If I am getting the turbo and the manifold for 650.

 

You still have to take into account the fuel system, miscellaneous plumbing, engine monitoring gauges (boost, a/f, etc), and labor (unless you know how to at least weld and do more than just basic maintenance).

Another Q: Are you sure you're getting a turbo that would be adequate for the KA24DE?

As much as I'd rather not say (you could have found this out on your own), you'll need:
A. Turbo section:
Turbo
Exhaust manifold
downpipe with O2 sensor fitting
oil send/ return lines
oil fittings for the turbo, engine block, and oil pan
coolant lines
Heat wrap/ sheilding
I'm assuming your turbo will have an internal wastegate

B. Fuel section:
Either:
Rising rate fuel pressure regulator (ideally 10:1 RRFPR)
High flow fuel pump
Or:
JWT ECU
Larger injectors and MAFS
High flow fuel pump
Or:
Some other more complicated fuel system

C. Intake section:
Miscellaneous piping
Miscellaneous hose connectors
Optionally but recommended (highly): Intercooler (side mount most likely, keeping things cheap)
Blow Off Valve and a flange to adapt it to the IC piping
Vacuum lines for wastegate, BOV, and to re-route the original intake vacuum lines

D: Engine monitoring:
Highly recommended:
Boost gauge (in case you drop a vacuum line or get a boost spike)
A/F ratio (in case your fuel system screws up)(A/F gauges are not to tune with, but they can help telling you if there's a problem)
Optional but recommended:
EGT (you'll know as soon as possible if your car is leaning out)
Oil pressure (oil is the life of your car)
Fuel pressure (accurate fuel system assesment)

E: Labor
Fit the oil pan with the oil drain fitting (oil pan needs to be removed and the fitting welded in place)
Make a downpipe with the proper flanges and O2 fitting
Fit the intercooler into the fender/ bumper (depending on if it's a SMIC or FMIC)
Bolt the manifold and turbo to the head, connect the downpipe from the turbo to the exhaust
Pipe the filter and MAF to the compressor inlet
Adapt old vacuum lines from the old intake to the new intake piping
Pipe the turbo compressor outlet to the IC
Adapt the BOV to the intake piping going to the IC
Pipe the IC to the throttle body
Plug your fuel system in, whichever one you go with.

I'm POSITIVE i've missed something here. This is NOT a guide to turbocharging, just a list that you can use to price out what you need to get minimally, and get an idea of what's involved. People can tell you that all that crap will cost anywhere from $1000 to $5000. Labor will cost a fortune and make up most of that difference, or it can be free if you have friends that are experienced or if you know a shop. You might be able to get great deals on some of the items used or online, or you might have to get them new somewhere. You're saying you got a great deal on a turbo and manifold for $650, I got mine for $450 including a turbo rebuild kit and BOV and internal wastegate. Someone else I know spent $1000 on the turbo alone.

 

Well if you can tell me where I can get a kit from for 450, that would be awsome.

 

I never said I got a kit for 450. I bought a turbo for $150 and a manifold for $200, but I had the manifold made by a friend.

 

look at the prices of turbo kits, and work from there...

if you dont know what your doing, you cant do it yourself, and a kit would be the correct way to go.
