Boost

[Importboom]

What all do you need for internals on the stock ka to be ready for a turbo kit. i kno u need pumps ecu, injectors. bore out the chamber bigger piston heads, new headers, am i forgetting anything? New exhaust, can u figure the boost setting for fuel and air mixture and program it yourself or do u need a shop if a shop isnt around for you to use at your own disposal? Just for reference

you really dont need any of that just to install a turbo kit on your KA. if you want to run some serious boost and rebuild your motor, you might want to consider buying the following parts:

-new forged pistons (probably ones to lower the compression also)
-new rods (eagle H-beam are probably the best on the market right now)
-upgraded valvetrain (i would anyways, i would upgrade the valvetrain just to put stiffer springs to get higher revs)
-a set of mild cams for street use (JWT probably makes the some of the best)
-ARP bolts and studs but sometimes they are included in the eagle rod kits

then when your done purchasing all that, take everything to a machine shop. have them balance the crank, hone the cylinder walls, and then install all the new parts. you will have a brand new KA that could handle anything well past 600hp. i probably forgot a few things. and that is JUST the motor part. you would also want many of other miscallaneous perormance parts to make that system work. BUT....that is just what i would do if i wanted to break into the motor....


you dont need headers beings the exhaust manifold should be included in the kit. you dont need to bore out your motor. you dont NEED a new exhuast. if you are really handy with electronics and you have the computer skills and hardware to burn your own chips then you can make your own performance ECU but i would leave that to the professionals. you will probably want to get some new injectors. pumps...which pumps???

well if your goin to make around 300whp or ( around 350 crank hp )

the stock block with really good fuel managment is more then enough.

if you want to run high boost, and make around 450 crank hp. you pretty much just need to change the pistons to forged lower compression units, and you dont' even need to change the rods, since the rods are forged from the factory. most people making just under 400whp usually just harden their factory rods by shot peening them. this is only a fraction of the price of upgrades rods.

you also will need new head studs, and new rod bolts, along with a new metal headgasket. and have your rotating assembly rebalanced.

all this should cost around 2500 bucks including parts and labor. not a bad deal considering that your gettin a brand new engine.

the cost of a swap will be 4000 average. and in order to break 250whp on a SR20DET, you need to change the turbo, the injectors, the mass air flow meter, and need some kind of piggy back to tune the thing, and dyno tuning time. this alone will be another 2000 bucks on top of the 4000 bucks.

for the KA with good fuel you can hit around 250-280whp and your turbo that comes with the turbo kit is usually good for over 400hp. so you don't need to upgrade the turbo or manifold, etc. you just need internals and fuel along with mass air flow meter, and tuning again.

both in the end cost about the same. but 2 very different approaches to get the similar results. but the parts list i just showed you for the SR shows you that its not as easy to get power out of a SR either. the stock turbo and injectors and mass air flow meter is the biggest limiting factor to making over 250whp.

yeah, your right. you really dont need anything but a set of ARP's and some new pistons but i was saying, while you got that block apart. i would go ahead and change a few other things. and yes nissan used some of the strongest rods to come in a stock block but for an extra $350 or so, ill take the significantly lighter rods. less weight moving equals less stress on pieces holding it everything together.

thnx for the engine tips guyz its apreciated you dont kno how much hahah. will i need like a new tranny and flywheel and other things needed to put teh engine hp to the wheels? clutch shifter etc. and also like fuel pumps and water pumps(yur question mentioned aboe)

[Importboom]

also for the turbo kit im going to put on there is there guna b a HUGE price diff between a single turbo kti and the twin. i like the twin idea better bcuz its giving you boosted acceleation through all gears as in the opposite one turbo itll either give you more accel in higher rpm w/ a bigger turbo and speed range or a smaller turbo give you better line off the gun accel?ty

yeah with huge amounts of power you are gonna need a upgraded fuel pump and clutch. fuel pump, i have heard you can yank off of a 300zxTT will support well up to 600hp or you can buy an aftermarket walbro or something. clutch, with huge amounts of power you will probably need one of the stiffer clutches you can get. i dont know how the transmission will hold up to the power but i cant imagine it failing if you are smart about what you do.

i dont know about the TT idea....i think it would be a lot easier and more practical to just buy a smaller turbo. with technology these days, you can easily get a small turbo to push out some serious power.

IMPORTBLOOM, please change your damn sig, ive asked like 3 times, just change the thing, its fucken long and makes you have to scroll all over the place to read shit...

[Importboom]

uhhh, no. bcuz you could have asked like a lil nicer then that and you dont have to coem into my thread and post sumthign that has nothing to do with it so deal with it

[Importboom]

ok thnx to all who gave info

[Hit_N_Run-player]

me and d-bo asked before....I have asked nicely, this was the first time i even had a bit of attitude, WTF IS YOUR PROBLEM!! why do you want to piss people off with having a huge sig that just makes them mad? just size it down or use the one you have in your avatar as you sig...pretty simple....and why would i post info in your thread when i know this is BS since your only 15 and you have the idea you are going to turbo a KA when you dont have a 240 yet....goodluck, its easier said then done..yes i remember your thread where you think your going to get a 300hp 240 and you havent got your license yet...thats why i wouldnt post in a BS thread to waste time....

sorry for any flaming, im not really an ass and will always be nice to you in the future like i have been in the past, but dont say shit like deal with it when im not the only one who wants you to change it...

Check your compression. But you will need to know what you are doing. You need to know how to select the proper turbocharger or you won't like it.
www.boostdesigns.com is your best bet for a budget minded enthusiast.
www.phatka-t.com has some stuff as well along with a bad-ass owner. He has some pretty amazing cars in his garage along with a S14 KA-T drag car in the works. At anything below 7psi, a FMU will do the job. 8:1 is a good choice. You will also need a intercooler if you go above 6psi. Its a good idea for any FI application. You'll need a wide-band if you want to tune it yourself. With any amount of usable boost on a KA, you're gonna need a LSD. Wheelspin becomes a huge problem. And if you size the turbocharger correctly, lag will not be noticable. Mine spools at 35-4000 and I don't notice any lag. Besides that, you don't want to be boosting all the time. The idea behind my kit and indeed turbochargers in general is the fact that you get boost when you want it unlike superchargers.

And for the love of god:
