Time to go Ka24deT! Need advice

[jcarney1987]

So I'm ready to turbo charge my ka24de and still expected to be a long term daily driver.

Okay here is my rough part list

I only plan on running around 9 PSI.

SR20DET T25 Garret Turbo from Ebay
CXRacing INTERCOOLER KIT FOR S13 SR20DET 240SX 89-94 + BOV
A Sandwich adapter for oil cooler and for turbo.
Excessive Cast Aluminum Pan with SR20DET Stock Lower oilpan.
CP or Supertech Pistons. (I know CP can take a bigger beating which I will probably go with those).
M2 Racing Bottom Mount T25 Turbo Manifold
SR20DET down Pipe

Basically all that should get me off the ground and running I would assume. Now my goal is to push around 200RWHP. So now bring the question I'm not really sure about how to go about and with all the articles on the web I'm left kind of confused about this part.

How should I do the fuel/Air management? Can it be left stock and do nothing? Do I need to add 440cc Injectors or bigger?


Any advice would help.

If I may, well... butcher your list. There's alot of room for improvement.

SR20DET T25 Garret Turbo from Ebay OMIT
CXRacing INTERCOOLER KIT FOR S13 SR20DET 240SX 89-94 + BOV OMIT
A Sandwich adapter for oil cooler and for turbo. OMIT, add http://www.z1motorsports.com/240sx/prod ... ts_id=4387 and http://www.summitracing.com/parts/atm-3 ... oCktHw_wcB if you're getting an oil pressure sensor (too much weight on the TEE alone)
Excessive Cast Aluminum Pan with SR20DET Stock Lower oilpan. Keep if you don't want to have a bung welded on your oil pan (a local muffler shop did mine for $20)
CP or Supertech Pistons. (I know CP can take a bigger beating which I will probably go with those). OMIT, not needed at the power as long as you have a good rom tune.

Add - Oil line kit (you'll need to find what fits or wait for someone to chime in), Z32 Maf if you have plans to push past 250whp, Deatschworks 550cc injectors, Walbro 255 or Deatschwerks fuel pump, and probably upgrade your Fuel Pressure Regulator while you're at it, I like Fuelab. If you can find a local tuner that can burn you an eprom chip, that would be cheaper, otherwise Enthalpy mail in tune is the way to go. You'll also need a clutch, I'd recomend the Competition street white bunny full face clutch kit. I'm sure there's more, but should redirect you on a better boost path.
.

Good luck!

Okay, I am trying to stay under $2000 on this startup if possible. So Basically let me make sure if I understood this.

To get started
Go with: http://www.enjukuracing.com/products/is ... 91-98.html
Oil line Kit
Enthalpy Mail in tune.

and if I want to push pass 250WHP
Z32 Maf
Deatschworks 550cc injectors
Walbro 255 or Deatschwerks fuel pump
upgrade Fuel Pressure Regulator
Upgrade Clutch kit.

Did I read that correct?

Should I not worry about using a oil cooler?

A small budget, i'm afraid will only get you in trouble, since two very rea lpossibilities will occur-
1. You run into weak points once you get the car going which may leave you with a broke down ride and no budget
2. You buy alot of parts but end up overlooking extra expenses that your budget won't cover.

I would say a comfortable budget going turbo on a 240 should be ~3500-4000, after all, you said long term daily driver. The turbo triangle says "fast, cheap and reliable, you can only choose two" and going turbo automatically fills the "fast" part.

Not sure how good the stock fuel pump is good for, but if your old stock pump dies (a $80-100 replacement part) during wide open throttle, you can pretty much guarantee a blown engine. A FMU (fuel management unit) is supposedly a cheap and reliable way to overwork your factory fuel system, but I would advise a decent work over like I suggested to keep things reliable and ready for future upgrades.

I don't know what a stock clutch will hold power wise, but be prepared to replace it regardless (I.E. budget for it) since a little abuse with turbo power *could* roast it.

It can get expensive on these aging cars, since you could end up replacing alot of parts that are basically at "end of life" anyway and will really start to show their age once you put some real power through the car.

No, I wouldn't worry about an oil cooler, save that for road racing or similar that has your oil temps (aftermarket gauge needed) asking for cooling.

If I had a 2k budget, I would do all the maintenance things (such as worn out suspension or clutch, any leaks or smoking issues, better exhaust) to the car first, then keep saving for a intro turbo setup like I linked.
