Hi guys. I got few question, i'd be really appreciate if you guys answer my Qs. This time, search button didn't help me very much, so i'm just writing a new post.

Engine compresion test result ( Single cam KA24 with app. 100000 miles on it.)#1: 150#2: 150#3: 150#4: 120

There was no oil leak, I think my KA-E is in good condition except #4 cylinder has low compretion. (Bad sign?)

This is the turbo kit that I bought from ebay:http://cgi.ebay.com/ebaymotors...=WDVW

Q1: I got a T3 turbo from Z31, but there are 2 holes on a turbo, one for water, one for oil. But seller did not included a water line...... so do i need to get water line from Z31? or should i just run oil line only?

Q2: Wastegate open at 12 psi, is it too high for my engine? (My goal is 250 HP, or 5sec 0-60)

Q3: should i just stay with 7psi, make around 200hp, be happy, uses stock injector and MAF with NO SAFC?

Q4: This's a real dumb question but is there any website i can learn how to install turbo? (Yes i know, i can figure it out, but since this's the first time i'm playing with turbo, i just want to make sure that i'm installing it properly, i know it shame on me, i was in auto class for a year but didn't learn anything about turbo.)

How long do you want your turbo to last? How reliable do you want your setup to be? You just answered your own question if you answered mine.

Perhaps if you are running stock injectors & MAF - they will max out around there. I'm not sure about the straight up t3, but for t3/t4, that's too high for fuel & such.

Basically, just start lower and tune up. Or just drive carefully to the dyno, you will only know how much your engine can handle after tuning it & driving it.

You could, but you will 99.99% get that "just a couple more psi" itch after about a week :-D.

Um, I hope you at least have read and know how turbo's work....... To install it, it's relatively easy if you search the gagillion threads on here.

Better yet, why not ask the seller, he's a member on this forum, he can tell you exactly where everything goes since it's his setup.

Basicalllly:

unbolt your old stuffput in new injectors/pump if you have itput on manifold turbo downpipe etcrun the oil/water linesrun the intercooler pipinginstall any sort of engine management

Since his setup was already complete, you should be able to install it ok... it's tuning that's a *****.

What year is your ka-e? Those compression numbers don't look too promising.

1. Yeah, you can run the turbo w/o oil lines, just don't forget to let the car idle for 2 minutes before you shut it off.

2. 12 psi is not too high for a ka that's in good condition with enough fuel. Take that for what you will.

3. At least get an fmu. They're cheap insurance for the most basic of kat's.

4. Yes. This one. Seriously, just read every thread here for a few months, and you'll be able to install it when the time comes.

yeah, is that why WRX's engine run for couple minites after you take the key out?

BUT you meant Water line right?

Yeah.. oops water lines.

But yeah, if the turbocharger doesn't have water lines, you need to time down the turbo. That's why most oem turbos are water-cooled -normal drivers are too lazy to sit in their car for an extra few minutes.

I don't know much about subarus, but if their turbos are watercooled, timing down their turbo isn't really necessary.

And if we don't all drive like asses just before we park, we wouldn't need to cool it down, haha.

I guess it would be simpler to get a turbo timer (or sit in your car) instead of plumbing the water lines, but it wouldn't hurt to be overly safe.

Car is 1989, the engine is 1990, i bought the engine from junk yard with 3 month warrenty. (already expired though)

Anyway, bunch of SR20DET people told me 12 psi will blow up my KA, so i was kinda affraid.

Oh and the water line wholes, can i just leave it opened? or do i have to close it with a bolt?

with the water lines, u can plug em up with a plug or bolt, whichever u prefer. as said before, u will need to get a turbo timer so that the turbo can get a little break b/f it is shut down. i can say from personal experience, u will definitely need to let the turbo cool down as the turbo u speak of is very boost happy. u shouldnt have lag at all when using that turbo.

Ignorant sr owners would say something like that. It seems like they're just trying to justify doing their motor swap.

But in this case, I might have to agree with them. That last cylinder isn't reading very good compression

I haven't seen a smic in person before, but I'm pretty sure that #3 goes back to the intake before the turbo, and after the maf.

And the small vacuum hose goes to any vacuum line in the manifold, usually the fpr vacuum line.

I don't know much about ka-e motors, but I'll take a stab at it.

1 is the pcv breather. connect it to the intake between the maf and compressor(7 or 8)

2 is the idle air line. connect it to the coldpipe(4)

3 I don't know. Carbon Canister maybe? It'll probably have to be plugged.

4 connect to 2

5 is bov recirc line. connect to intake between maf and compressor(either 7 or 8)

6 is bov vacuum line. T it off of the fpr vacuum line.

7 and 8 connect to 1 and 5

I think that should be it! Good luck!

I forgot 9...

when you remove your exhaust manifold, you remove that too and plug up whatever vacuum lines are attached to it. You'll get rid of that whole mess with the kat.

No problem. I'm just sharing what I've learned to the new generation. I expect you to do the same when the time comes.

# 1 you might want to put a catch can in between the hose -> maf/compressor location

# 2 goes to the cold pipe, huh? I better start checking my wiring I will be doing, haha.

# 3 is not for the carbon canister - at least I don't think so, when I removed my canister w/ wiring, that one was untouched - it's one of the other vacuum sources that gets tee'd off from something else.

I had thought that we were suppose to hook up all the hoses that go to the intake -> between compressor & maf. Good thing I checked out this thread about the idle-air line.

Now the only thing left in the air is #3.

O yea, and if you can wait til like Labor Day Weekend, I could probably help you install it, haha - we can have a massive "work on our 240" days or something, plus it will give u 3 days to get stuff done, haha.

I still need to finish up my electrical & fuel crap first

wait, correct me, #2 goes to #4? I thought #4 is hotpipe.If everything suppose to go between MAF and Turbo, then #4 and #2 doesn't make sense... #4 is right before thorottle body. (the picture looks little weird)

(ps. that air intake pipe and SMIC is from SR20DET)

Well, if #4 is b4 throttle body, that would make it the cold pipe (after intercooler).

Yea, I was just making a comment that I was going to put #2 in the wrong place for my install if I didn't read this thread.

In the mean time, you can do what I'm doing, i.e. install fuel injectors, pump, gauges, oil pan stuff, etc. I'm doing those over the next few weeks.

You may even want to start running intercooler piping test fits, etc.

Then when turbo time comes, you just have to hook up the mani, dp, intercooler, and WHAMO, done.
