14b install half way done - need some suggestions

[lowandsleekDSM]

Ok everyone, im doing my first 14b install on my 2g and ive been trying to follow the install walk through on VFAQ.com and its been pretty good to me..and plus a lot of the stuff is pretty much plug and play if you really think about it. Well ive hit my first minor speed bump. I wanted to get some suggestions first before bolting down the water lines and such. Now the 14b that i bought some 7 months ago came with one water line already which is a relief. (The water line in the back of the turbo....the return line which hooks back up to the line thats bolted to the block i believe?) But im running into problems bending up the other water line. Heres some pics i took just for reference:

I used this line (it just looked like it would fit pretty much i just bent it just a little and the wastegate arm clears too)

Or should i have used this one instead?

And is there anyway to clock the housing just a little bit? I had to stretch the wastegate actuator just a little bit to bolt it on to the housing of the 14b? I know there is like a clamp in between the turbine housing and the exhaust housing - do i use that to clock it? Any info that could be useful would be greatly appreciated.

you can reclock the turbine housing, but there is a pin that lines up the cartridge with the housing. youll have to grind that off or something. if you reclock it though then the wastegate flapper will not line up with actuator arm. i suggest getting the right wastegate actuator if your using the t25 one. Or you could look into going with an external wastegate which will hold boost better than internal gate.

 

[lowandsleekDSM]

Well it is the 14B wastegate for sure. Will i run into problems running it? To me it looks like it needs to be clocked ever so slightly so it doesnt pull on the arm too much. I tested out the flapper and it seems pretty good in opening, i mean it does not bind or anything at all. Im trying to do this on a small budget as possible, this is actually a fix to get rid of my blown t25. I should of taken better pics of the wastegate though to explain this a little better sorry about that.

 

[lowandsleekDSM]

Wait what other one are you talking about? I only have one wastegate and its the 14b wastegate. Im not using the t25 wastegate if thats what your talking about?

p.s. - I did a little reasearch and i read that when the actuator arm is pulled out of the wastegate a little bit (which is my problem right now) it in facts lowers the boost a little bit...so im thinking i can make up for the lower boost with a MBC that i have already. Which im sure my ported 14b will have a much better punch at 15lbs. then a t25 at 15lbs, so im good there

 

[toofast82]

you could put some washers where the wastegae mounts to the compressor housing. i would hook up a vacuum pump to verify the actuator is properly working. if its the correct actuator there should be no fitment issues

 

[lowandsleekDSM]

That vacuum pump idea is a great idea, i dont have anything like that though i dont think. Ill try to washer trick but i think it might put the wastegate up higher and pull the arm out even more limiting the wastegate flapper movement. Hmm i dont know maybe im just thinking too much into this maybe?

 

[Imback]

you are just reuse your water lines of the t25

 

[lowandsleekDSM]

Oh yeah i know that, ive got that kinda figured out. I took some pics on what im talking about, once again i think im thinking too much into why the wastegate isnt fitting quite perfect.

Heres the wastegate installed...notice the distance from the bracket and the little tab?

Here is the wastegate just unbolted...now look at the distance of the bracket and the little tab.

And this is how off the wastegate is when its unbolted. Is this a 14b wastegate?

Now once again, i could very well just be thinking too much into this, but i just want to make sure that this would not be a problem.

 

[toofast82]

i would say so, i bought a used 14b and it seemed the wastegate was too long too. i put two washers on each bolt and it was okay. For some reason the wastegate off of my auto 13g fits perfect on the 14b with no washers and keeps the flapper shut nice!

 

[viprez586]

G'luck with that 3" downpipe. Stock flapper + porting i had boost creep to 20psi.
Only time will tell, some people luck out.

Also if your looking to push 15psi on the 14b, please...bare minimum rewire your fuel pump if you haven't done so already.

 

[toofast82]

i would recommend the rewire as well, but the 2g pump does flow a decent amount more than a 1g pump. i wouldnt go higher than 14-15 w/out the rewire

 

[lowandsleekDSM]

Oh no the MBC will come in much later on. I thought about it and i just wanna run stock boost for right now due to lack of supporting mods. The o2 housing and the exhaust port is ported also (where it bolts up to the exhaust manifold). Im not sure about the wastegate flapper or anything. Just to make sure, boost creep....would a tubular o2 manifold would do the trick? or a o2 dump? Not too sure about a o2 dump for a DD but, hey if it works then it works

 

[gorf]

water lines- use your stock t25 banjo bolts and tubes, bend the steel part as little as you can just enough to clear the housing and use longer piece of rubber tubing, I used hydraulic line from power steering line - worked great.

 

[lowandsleekDSM]

Yea im going to use reinforced fuel line. I used that on basically all my oil lines running to the oil filter housing and the water lines when the t25 was on my car. Now im guessing the water line in front of the turbo goes to the feed line that points down right? And the water line in the back of the turbo goes to the return line thats bolted to the block and facing the radiator? Just making sure.

G'luck with that 3" downpipe. Stock flapper + porting i had boost creep to 20psi.

I just noticed I'm also creeping to 20 in 3rd gear, its staying at 12 in 2nd. How'd you fix this?

 

[JusMX141]

LowandsleekDSM, don't try to clock the housing. It's a huge pain for a turbo that is internally-gated and generally is done only on turbos that are set up for an external gate.

Your photos of the wastegate arm tension are completely fine....you want a little tension on the arm holding the flapper shut or you'll have trouble building boost initially.

 

[toofast82]

i know on 1g, the water line on the radiator side goes to the water pipe and the one in back of the turbo goes to thermostat housing.

 

[lowandsleekDSM]

Yea i looked at clocking the housing and i just decided not to. Just to be on the safe side. Ill be finishing up the install here in a couple of days, ive come donw with a bada$$ cold and i feel like crap. Hopefully i wont have boost creep with my dinky little setup

I didn't want bother messing with internal gate and hoping it would work. I ported the crap out of it too. (Might of been why it crept to 20)
Had a 38mm tial knock-off laying around, so i picked up the SBR mani, bolted it up. Ahhhh rock solid boost.

 

[lowandsleekDSM]

Hey Viprez586, I was wondering - to go with an external wastegate, do you have to weld the flapper shut? or is there another way to keep it shut? Because im thinking this will be better for me to go with an external wastegate when i get the money, then to go and upgrade my fuel to handle the boost creep i might get.

 

[JusMX141]

Depends on whether you choose an external gate off the manifold or off the o2 housing.

Personally, I wouldn't use an external gate on a 14B unless you were planning to run extremely high boost (levels that would not be achievable with an internal gate). An internal gate should easily control your boost unless your exhaust system is too unrestricted.

 

[lowandsleekDSM]

Too unrestricted as in not having a cat? And having a 3inch DP with a 2.75inch catback possibly? Im not really worried about boost creep or anything because i can just take it easy with the car until i can figure things out i dont mind that at all. Im just looking at my options right now.

 

[viprez586]

Like posted...

Ext. Gate off manifold. Weld flapper shut, I've also heard of people wiring or rigging it shut.

Ext. Gate off O2, remove flapper or wire it open.


Sure, good porting and 34mm flapper you could achieve the 14b maximum and maybe not encounter boost creep. At my stand point i looked at it as..."well $200 and never look back" since SBR had a sale, and their manifolds are also redesigned so they don't crack. I've got 15k on my manifold. It's up to you and what your plan on upgrades contain.

Thing that concerns me is your creating a " bottle neck " in your exhaust system going from 3" down to 2.75". This may or may not cause problems but it is a form of "restriction" nevertheless.

 

[lowandsleekDSM]

well like i said before, im on a small budget atleast for the next week or so. Now i have another question, ive heard that either a recirculated tubular o2 housing or a o2 dump housing can cure boost creep. Im not looking for the easy way out because i just wanna run this turbo, but i really dont want to open up the turbo and get myself into something i have no knowlegde of. Plus i want to kind of get my car back on the road but i want the car to run as safely as possible. Didnt think there was so much to go into on a 14b install Thought i was in the clear about everything till the subject boost creep came up.

damn i had no idea that there was this much to it either, i'm doing a 14b install tomorrow with a MBC on my 2g and i'm not running a bigger fuel pump then the stock one right now, now i'm trying to figure out if i'm going to have boost creep and how much of it i will have. maybe now's the time to look into some other supporting mods
