so it starts: PPT 3071 "build"

[kevdakaotic]

so you think you fried the ECU? Do you think crossing those white wires on the o2s coulda fried it?

oh well. You will get it. Nothing good comes easily most the time. Just keep pressing on.

[jstnGTI]

I put quick connectors on the harness side and stupid me didn't wrap them in tape so I think the shirt happened when they touched. found an ecu kinda locally (3 hours) and flashed it the correct way and it ran!

Took it out for a drive, had some issues.

got some kinks to work out, but it'll come along.

[kevdakaotic]

Did you build the head at all? I want to do basically the same build, but I want to throw some exhaust valves and springs while I have the head off...maybe polish the ports.

+1 on that.

@jstnGTI, well done bru. It's the home stretch now.

I wish the rand dollar exchange rate would drop so i could go BT on my car.

BT 1.8T 20v FTW!

Nah, didn't do any head work. just cleaned up all the carbon build up and the deck before putting it back on.

something large port would have been nice , valves prolly would've been nice too. just wasn't any room in my budget for valves, unfortunately.

[kevdakaotic]

yah, this build isn't really in my budget, looking at about 7gs...I figure whats another grand?

I think I'd puke if i added up all the money spent on this build, hahaha.

it's the little things that rape.

hose clamps, hoses, hardware, fluids, ciggarettes, last minute specialty tools, impatiently overnighting things, replacing things you fck up, etc. etc. etc.

[20VCanuck]

I just did a bt build, no where near as awesome as yours but I bet I hit the parts store 15 times in two days while I was building it. Probably near 5k in parts over here.


You should bring this down to Great canadian at the end of the month!

[jstnGTI]

hmmm. okay.

initially i had a huge problem with oil getting everywhere, smoke for days, etc.
thought i had a turbo problem, but i called a local place that rebuilds turbos, and they suggested checking my crankcase pressure, and "angle of oil return."

did some investigating, and realized my catch can was hooked up incorrectly, and the oil return line wasn't making a straight route back into the oil pan.

sorted those things out last night, changed the oil from ND 30, (after the initial break-in) , ran the car down the street after it got to temperature, and things seemed to be looking up.

extreme decrease of oil smoke, spillage, things like that. and the turbo actually built boost. very shortly, brief, but i know it did.
hit 15 on the small road in front of my house. (open downpipe, didn't want to get pulled over in the street.)

i got pretttttttty excited.

here's the problem, i let it idle til it warmed itself, then tried to take it out.
no boost at all.
ran codes, nothing.

no matter how much throttle, doesn't go past 0.


what kind of things should i be looking for? should i be seriously concerned with something vital? i know i need to take a compression test to monitor how the break-in went, was having problems during that time, again...

[20VCanuck]

sounds obvious but your boost hoses to see if one of them blew off,

[jstnGTI]

checked around. no dice. I increased the boost on the mbc, with hopes the wastegate was stuck open. I'll check to see if I have any luck the next time I can run it again. waiting on exhaust to come in so I can do actual road tests. 3" open downpipe is waaaaay too loud.

[jbdubn]

Try running off your wastegate spring only. Maybe your mbc is hooked up incorrectly?

[jstnGTI]

the mbc came with a diagram, haha. I'll try it though.

[l88m22vette]

Why not use the N75 to confirm things work? Maybe its just me, but MBCs seem to work as often as not (my TT never liked the HPBC I have in a drawer)

[boosted b5]

arnolds kits have changed alot as far as appearance since Val(BT 18T) and i got our original T3 kits. i think alot of my feedback to Arnold helped with that stuff. hes a great guy, and listens to all of his customers input as far as small fit and finish details are concerned.

here is what my setup looked like. started working on it in 2007 working with Arnold on the FMIC layout, what was originally going to be a passenger side dual pass, i wanted it driver side with a TT manifold, so later i could run a SEM. the hardware fit great and performed even better



still wrapping it up. OEM battery and battery case fit like a glove



silicone outlet, to pancake, to PPT pipe.



FMIC and pipework




i loved my PAG kit, it was perfect on the street, drove better than stock and surprised A LOT of people.

Deleted and resistored.

Hallman pro mbc? That's the one I got after the nut and bolt blew out of the one I bought from silverjetta. my fault entirely.

jstnGTI, please check your PM

cheers bud!

[jstnGTI]

my apologies for the lack of updates/neglect towards this thread, but I just got the car up and running smoothly.... kinda.

I think I have to try to dial in my boost controller. as of now, nothing hinders the boost from reaching 30+ (that's how far my boost gauge reads). I have to kinda ease the pedal along in order to avoid something terrible. I know this because I stepped on it ONCE, and my boost gauge went crazy. got scared and said i wouldn't do that again, hahaha.

got 20lbs over three springs in my wastegate, and I still haven't loosened to the boost controller all the way to see what happens. my goal is to boost 20-22lbs.

going up the rpms is pretty choppy. like, it's stumbling. I'm going to go ahead an attribute that to the sht coil packs. will upgrade to 2.0 real soon.

any suggestions would help on the over boost issue.

I'm going to make an effort to hit the dyno and get some videos up soon for you guys!

thanks for watching!

[jstnGTI]

sounds obvious but your boost hoses to see if one of them blew off,

Turns out, this was exactly it. ic clamp right off the turbo blew off.


props!

If there are three springs in there, take out the small burgundy one. Do you have the vac line on one of the bottom ports and everything else plugged? The top has to have at least one open if you're using an MBC. Sounds like you need to gap the plugs

[boosted b5]

over 24psi i ran the 4554 plug(8 range) gapped at .020" and it ran great

Hey Arnold! nice to hear from you.

yes, all the unused vacuum ports around the base are plugged. the one on the tippy top is open and the one directly below that.

i thiiiiiink that's correct?

then again, I haven't heard the wastegate open yet.

Glad you have er' going. Ha, wow your having the same issue's I have been having on my build.

I was boosting to no end when I first had it going. I had the mbc on backwards. Running no tension on the mbc (Or try running a line directly from wastegate to vac port on manifold) should result in running off wastegate pressure.

Im also having stumbling issues when part throttle driving and sometimes in boost. Im going to close the gap up to .26 on bkr7e

Goodluck!

Hey Justin. Rotate the gate so the dump is closer to the valve cover bw the intake and head so it gets away from the inlet pipe. You can angle it appropriately because it is an open dump. You have it plugged in fine and perhaps need to adjust your boost settings and take out the smallest spring in the wastegate. You can experiment w/ spring rates as well but you should only have two springs in there to start as tial seems to want to package them with 3 springs by default.

[jstnGTI]

^okay. I'll try it tonight in a vise. it was TOO hard to close that wastegate by hand. doing it after the motor was in was a bad idea! hahah

the mbc came with a diagram, and I installed it accordingly.

the wastegate sounds like it's fluttering, which I think means it's trying to open, but can't.

we shall seeeeeeee.
Thanks for everyone's help!

[AL@PagParts.com]

Yeah its tough. Thank goodness for 20 ton presses in the shop but gotta be careful

[Big_Tom]

My foot is a 20 ton press (;
Haha

[formerly silveratljetta]

This is the best tool for holding the wastegate closed during reassembly. It won't scratch it like a vise either. You can purchase at any home depot

[jstnGTI]

are you serious?! I own one of those and have never used it! honestly I don't even know where it came from. haha.

I planned on using cardboard between the vise and the gate. protect it. it's so slick looking, you know?

the rubber pads on the vise will protect it. I put the maximum spring pressure in it using that vise.

Whoops my bad

[jstnGTI]

well, I tried the black spring (.4 bar) and the blue spring (.4 bar) for a total for .8 bar for a total of ~11.6 psi. Have the mbc adjusted nearly all the way out. still no control over boost.

Hallman pro mbc

installed according to this.
Tial 38mm mvs[?] wastegate.

I think it flutters less with the subtraction of that third spring.
