project turbo

[RPS13guy]

i need some serious and concice advice. im turbo chargin' my k2d, im shooting for no more than 305 to 315 to the wheels. im looking for lots of torque, low boost at high rpm with minimal if no work to the engine. i'm looking into a mitsubishi super 16g turbo and lc pistons ratio:7 1/2, maybe an upgraded fuel rail from sds, but i think i can manage with out it. what advice can you give me?:help

"wake up"

must agree, stop daydreamin

"wake up"

agreed

w/o doing internal work, 315 horsepower is cutting it close i think....so yea, smack yourself and go drink some coffee

Dont think your stock internals will handle the boost required to make that power. They might survive for a little while, but not long.

all i was asking for was advice on how to turbo my girl with least possible work to her internals, but you guy's spat on me and for that ya'll can suck my exhaust pipe and die. this is a public forum, if ya'll ain't got advice, don't give it, but don't knock my s-hit, it just makes you look ignorant and green. grow up kids, and learn how to get along with people that might in the future help you're stupid a-s-sses with a project. :patriot :

I must say that you are the one looking ignorant and stupid. "Ya'll can suck my exhaust pipe and die..." blah blah blah blah. If you were such an educated guy, you would of known that the ka motor is not realtively stable after 10psi or above and the 16g turbo needs more than that to spool up totally, not to mention you crying about how you didn't want to touch the internals. Good god man!

So far, noone who responded to this gave any kind of a definite answer. Frankly, I don't think anyone knows what they are talking about. Seriously though, if you have a KA in good condition, 300+ HP is possible with stock internals. Just make sure you have enough fuel to compensate for the extra air. I'm not very familiar with Mitsu turbos, so I don't know if a 16G will be a good choice or not. Even if you build the motor, 7.5:1 Compression pistons is probably a lot less than you will need. For the HP levels you want, you can stick with the stock compression. The lowest I would ever go would be 8.5:1. To achaieve 300+ HP, you'll need to be boosting about 12-13 psi of boost minimally. Depends on the turbo you use. As far as a fuel rail, if you decide to use top feed injectors, you will need an aftermarket rail. There are side feed injectors available that will fit, but they tend to be pricey.

Kwik, you obviously didn't read his post. He said he didn't want to touch the internals, that's the problem everyone has with his question. It can be done, but it really shouldn't.

C-Kwik,Bout time someone gave him an answer instead of insulting him.Thank you.

To the rest of you,You could try to answer a question with out being total jack a$$e$.

RPS13guy,"ya'll can suck my exhaust pipe and die." That is a bit excessive. There was probally a better way to express your anger. A mature way.

Okay, I am done b!#$%ing now. We should all try to be a little nicer. We are all on here to learn and share info.

I think Rodney King said it best (after filing a lawsuit against the LAPD) "Can't we all just get along."

Of course their response was, "No."

[Former_240_s14]

I don't think we were being that insulting, we could of been a lot worse Jester, you know this!

[JESTER]

Yes, I do know that. I have been an a$$ myself many a time.

Maybe I am getting soft in my old age. Maybe it is all this Whiskey I have been drinking.

Anyway, sorry to rant. Lets just not run off all the new people. We were new to the forum at one time.

I'm quiet sure your KA could produce 300 hp without ever lifting the head. But you will need to run a serious amount of boost. Lets use my usual equation for hp. For every 1 psi you'll gain roughly 10 hp. So lets say your KA is already sporting 150 stock. Lets assume you'll need to run 15 to 20 psi depeneding on how efficient your engine will produce hp through forced induction. Thats quiet a bit of boost for stock internals, but to much.

You'll need a fuel system designed for high boost applications and an engine management setup for the same. You can't have one without the other in my book. I would suggest a Haltech personally, but there are quite a few suitable systems on the market. You'll have to do that research on your own according to budget.

The key is going to be running boost without any indication of knock(detonation). Knock is the killer of forced induction motors...trust me I know.

So I always recommend a stand alone alcohol injection kit. I've used them for years. Running alcohol will allow for increase in boost from 6 to 10 psi over pump gas. By using a dual stg boost controller. You'll be able to save the higher boost runs for racing or the track. Explaining this process is more then I want to get into at the moment. There are alot of variables when using alcohol and tuning for high boost.

But with the above recipe you should be able to squeeze out 300 or so hp.

My internals have been totally redone, everything's new. only thing i've yet to do are the pistons, i'll take your advice and check out the 8:2 compression one's. My engine has been rebuilt and is now exactly as it was the day it came from the factory. 300hp to the wheels, along with the lc pistons, upgraded fuel rail and performance head gasket, i'm assuming should work. and after speaking to several other people, i've been told it may. the engine's getting dropped in after i find a suitable turbo for the desired boost and power im going for. but all in all, thanx for the advice, it'll really come in handy. :ylsuper
