14b turbo on a 2nd g

[airbrat]

another quick question guys. is the factory J-Pipe from a 1st gen 14B sufficient for the 2G install??? I heard that its too skinny when using on your 2G.

 

[nine5raptor]

works fine for me...

Somebody should sticky this

what you need:
-j pipe or other flanged pipe to connect to compressor outlet
-oil feed line...dont skimp, just get a good quality ss one.
-oil return line, or modify your t25 oil return line
-water feed and return lines from off of your t25. they can be shaped to accomidate the difference in shape of the turbo easily.
-o2 housing from off of your t25

you can skimp on gaskets. personally, i only replaced the manifold to turbine gasket. you dont even need to take the mani off, so the exhaust mani to engine gasket is unneccesary. anything after the turbo i really dont care about leaking, so i just reused my turbine to o2 sensor housing gasket and o2 sensor housing to downpipe gasket. as long as they dont deteriorate in your hand you might as well use em again.
i wouldnt skimp on the oil return line gaskets. go ahead and replace those. oil leaks suck.

no doubt! this is one of the best threads I've ever read dealing w/ this specific issue

Ok guys i finally got my 14b and its ready to be put in. The only problems im having is getting the damn water pipes off the t25. I sprayed it with pb blaster and it still is hard. Do these just screw off at the bolt on the turbo housing? Does anybody know what size socket i will need to get it off because my adjustable wrench isnt working. Any tips would be great.
Thanks

Hay, is it easier to do the 14B install with the mani on or off? how hard is it going to be to get off? i have a die grinder, so should i just take it out and port it to match the ported 14B (7cm gasket match?)? is it worth the pain to take it off? what kind of gain will i get?

 

[Blitzed95Eclips]

i took it off because i like to have lots of room. Besides its not that hard to get it off. All you have to do is take out the radiator fan and unbolt the mani. It should just pull right up. It makes getting the o2 housing off sooooooooooo much easier.

 

[Mr. LEaKS]

thats it im going 14b!!!!!!!

 

[bigjangin]

the manifold is the toughest thing to get out, but its very easy to break the studs. Especially if its never been off before. I wouldnt take it off unless I had to.

I'm gonna add my 2 cents here, having just installed a 14b the other day on my 2g.

First off, I re-used EVERYTHING except the oil feed line and oil return line. For the oil lines I used 1g ones without problem. I got to my friend's house, we let the car cool for about 15-20 minutes and started on it. The turbo to mani bolts came off really easy with everything still being warm, didn't even use PB blaster. We unbolted all the lines we could at the turbo except for the water feed, so we just took the hose off the top of that and left it connected. The turbo came off without taking the manifold out, but the J outlet of the T25 was hitting the front motor mount. We tried to turn the turbo sideways to let it drop down but the o2 housing's heat shield was hitting the block(couldn't get this off, bolt was siezed) so some tin snips took care of that and the turbo dropped right down. Next we prepped the 14b to go on by putting the water lines on(re-used from T25), and bolting it back to the mani. The re-used water lines reached the stock rubber hoses fine, with hardly any bending. Next up were the oil lines, no problems there. You will need a 3/8" NPT plug to plug the T25's oil source unless you bought an SS line that still takes oil from the filter housing. I used a stock 1g oil feed line which is sourced from the head. Next we started on the piping. My friend previously gave me his stock compressor outlet pipe, so we coupled my existing Greddy LICP right to that, and ALL that was needed now was a 45 degree coupler(I used radiator hose for this) to connect it to the stock IC. Much easier than I thought. What we did beforehand was went to Autozone, looked through their selection of radiator hose and found some 2" that had a few bends in it. Now if you do exactly what I did, the weight thingy on top of the tranny might hit the lower pipe and make it hard to get in and out of gears 2/4/R. You can hack this weight off with no side effects so I'm told, I just haven't had a chance to yet. Next we bolted the DP back up and we were ready to prime the turbo. I pulled the triangular connector off the coil pack and cranked the car as follows: turn the key and crank the car for 3-4 seconds, pause for 5-10 seconds, and repeat 5-6 more times. After this I plugged the coil pack back in, cranked the car, and let it idle for 10 minutes. Next we went for a drive WITHOUT BOOSTING for about 15 minutes. Finally I tried to spool it, and discovered I had a really nasty boost leak. We forgot the tighten the 1g outlet pipe down and needed to re-couple the UICP at the TB elbow and now she was good to go. First time hitting it, the 14b hit 15psi and scared the shit out of me....then I hit fuel cut, DOH! Yep, after holding 15psi briefly, she creeped up to 17-19psi. Now I'm running only off the wastegate and it will hold 10psi until about 5000rpm, creep to 15psi, hold there briefly, and still hits 17+ psi causing fuel cut. 10psi feels like the T25 at 15, then when it kicks to 15psi it's crazy, a HUGE improvement.

My suggestions:
1. Port your 14b and o2 housing while they are off unless you want boost creep, I have a 2.5" pressbent downpipe(I thought this might prevent boost creep but I was wrong), unported turbo and o2 housing. DO IT RIGHT THE FIRST TIME, I didn't and now this stuff is going to have to come back off.

2. Get a stock 1g compressor outlet pipe, this will make it much easier to route your existing hard LICP, assuming you have one.

3. Hack the weight off the top of the tranny/shift cable.

Like I said, other than the oil feed and return lines, I re-used everything from the T25. Now if I could only solve this creep. My friend with a 1g has an identical setup except a 3" high-flow cat while I have a test pipe, and he is not having boost creep, so I'm puzzled.

 

[nine5raptor]

Mine didn't come anywhere near the weight, but then I modified the stock licp.

The highflow cat is more restrictive, therefore his system is less prone to creep.

 

[Spidey]

Ok, lemme be specific, I have a 2.5" pressbent downpipe, mated to a 2.5" test pipe, mated to my 3" cat-back. His downpipe is 2.5" until the the flex section, and is 3" all the way back including the high-flow cat. I assumed because of my DP being press-bent it wouldn't creep but I guess I was wrong about that. I think I may throw my stock cat back on or buy a high-flow cat rather than taking everything back off first, what do you think?

 

[nine5raptor]

Porting the wastegate area of the 02 housing would be best, but a cat would help (although it would hinder performance). the only time I creep higher than 15 psi on my completely unported 14b/02 housing is if I run the car extremely rich and still have fuel burning in the exhaust.

Two pages of thread and no one has checked the Tech Articles section. Ludachris is crying a single tear.

Many thanks to our vegetable friend Cucumber.

SPIDEY: You say that you get creep up to 17+ psi and then you fuel cut. On my 14b w/ a 2.5" test pipe, and 3" catback I can run 20 psi before I fuel cut. Right now, I have no boost creep whatsoever. However, Im trying to get a 2.5" downpipe put on. At that point it appears that are rides would have similar mods. So my question is, exactly how much boost creep are you seeing.

 

[14.5 drift]

how much hp can the 14b support?

 

[spoolinawddsm]

i installed the 14b on my 2g for nothing but the cost of turbo, if you can get the oil feed line from a first gen youre golden.

 

[Spidey]

pickens - it will hit 19 if I don't let off. It has hit 17 without fuel cut a few times but I would let off before it got a chance. I will be tossing my cat and boost controller back on within the next few days hopefully, to see what happens. So yeah, it is creeping from 10psi to 19psi, running only on the wastegate.

 

[stjoetalon]

I reused my oil feed line with an adaptor fitting. Im not sure what size the threads are though(it has been on for a few years).

I slotted the bolt holes on my return line.

Used a 1g outlet pipe, a few feet of exhaust pipe from muffler shop(5 bux), about a foot of straight radiator hose(cut up into couplers), and some hose clamps I had laying around.

All lines, crush washers, and gaskets were re-used without a single problem.

I probably had less than $10 in the whole thing, but I had some of it laying around.

INSTALL KITS ARE BIG F*&#ING RIPOFFS!!!

I am going with a braided supply line when I redo it though.

 

[bluelightning92]

im no pro, but your saying you have boost creep from 10-19 , but you said you don't have your boost controller on? that doesn't make sense to me, but maybe i don't know anything

 

[pimpngear]

Cheap install???
