Stop being such a quitter. We'll get that thing running next weekend when I'm up in the area. I'll give you my DSMLink user info; you should be able to cross reference most of the info/tips etc on that board to at least get you in the ball park.

boost leak? or MBC not hooked up yet?

[a4spoolin]

mbc is hooked up. i def have a boost leak. i brought it to work today ill be smoke testing it and a buncch of other stuff

If you want to get the most out of your turbo ditch the MBC and invest in a EBC and hook up both ports on the WG.

what does hooking up both ports do? I thought the top one is left alone?

[Mike@Ringer-Racing.com]

what does hooking up both ports do? I thought the top one is left alone?

Both are used when running a EBC, the side one is only used when running a MBC or a N75 type valve that sends pressure at a set boost to open the WG.


When you run it as a dual port you run direct pressure to the side port and then a line from the EBC motor to the top port. The pressure going in the top port helps keep the valve closed as the pressure in the manifold increases. Just like how pressure on the top of a BPV keeps it closed. When the EBC reaches its boost setting it releases the pressure from the top port allowing the valve to open quickly and close quickly as the motor reapplies pressure.

When you run the WG just as a single port with a line to the side of the WG there is no pressure at all till the valve needs to be opened and there is no pressure helping to keep the valve closed as the manifold pressure increases. This is why there is such a big advantage running a EWG with a EBC. Chris on AZ found this out when he decided to change from a single port internal WG using a EBC to a external wg so he could use the dual port option with the EBC.

[a4spoolin]

ya will be picking up a ebc soon. once work picks back up and i got cash flow ill prob get the aem tru boost. i gotta do more research

[BigZip]

BigZip thinks you should sell this abomination. BigZip thinks you should take the money from the sale and buy this bicycle. BigZip thinks it will be safer and suit a4spoolin well.

[a4spoolin]

well turbo and mani are coming off to fix an exhaust leak which is the reason for my lack of boost

[a4spoolin]

well got the turbo off and found this. this is why i cant build much boost

[Mike@Ringer-Racing.com]

That will do it. Got to make sure those bolts stay nice and tight. You can try going without a gasket, just have to make sure both surfaces are perfectly flat.

[BaconBait]

I might have an extra if you still need one.

[vweater1369]

Whats that gasket made out of? Copper Gasket spray is your friend.

[a4spoolin]

i checked the nuts quite often and they were tight. when i took the nuts off, the studs came out of the mani on the side that the gasket broke. so that's prob why. Im switching over to bolts because i can't get the turbo out if studs are there without taking the mount off.

I might have an extra if you still need one.

Im gonna call some shops tomorrow and see i can get one.

multi-layer steel

[a4spoolin]

well ordered a gasket from extremepsi but they wanted 50 bucks for overnight saturday shipping. i couldnt justify spending that much so ill have the gasket monday. also ordered a spring kit for the forge bov so i can fine tune it when i up the boost past the spring level in thats currently in it. goal is to have it running, inspected, and running a solid 25psi by next weekend. not too confident on the last two goals lol.

[BaconBait]

Good luck!

[03b6avant]

DOnt run one! I dont run a gasket. Kept blowing them apart. Checked them make sure they were bothflat and mounted the turbo to mani. No issues for a year now......(knock on wood).

[a4spoolin]

yea i actually decided to go gasketless give it a shot. im picking up my new manifiold gasket from the dealer in the morning then ill get wrenching hard and hopefully have her running by mid afternoon then tune tune tune.

[03b6avant]

when you getting this running. I have to go back up and do another Dyno Run. My car did SHIT. Knock Sensors threw a code and car just wouldnt make power.

[BigZip]

BigZip wants updates on this build thread now

[03b6avant]

me too i want updates.

Update on mine: new plugs Coilpacks on order, fixed the TIP to the turbo and removed the 3"maf now running the stock (like the tune was intended for) BUT.....misfires or stumbles at WOT. If i easy into 23psi it holds no problem?

[a4spoolin]

BigZip wants updates on this build thread now

Zip, are you actually inquiring about the build instead of just ripping on me?

Well I went to get inspected again today and failed haha. But I had a CEL come on on my way to the inspection and cleared so I failed for cat and oxygen heater. Changed some settings in Maestro, went for a quick drive and failed only for the cat. So I'm hoping I can put some more miles on the car and it will pass. I'm going back tomorrow so hopefully it works.

Been working on the car the past few nights. Changed an 02 sensor, fixed some oil leaks, and took apart the wastegate. Found out that the new gate was operating solely of the red spring (12psi) instead of both red and yellow for 16psi. Tried to reinstall 16psi of springs but the tension was too strong. I'm currently running only the 4psi spring but have the mbc turned 8psi haha so that was kind of a step back. I've actually seemed to better the running of the car the past few days, so hopefully she will be running solid very soon.

Did you order the fsi coils? Have you scanned for codes? Sounds like a possible vacuum leak, espcially if you were playing around with the tip. Im surprised the tune calls for the stock maf with that size turbo. Your still running revo right? If I were you I'd prob look into another tuning solution whether its Uni or Maestro.

[Sideways]

Get all the bugs worked out yet, Wacker?

[a4spoolin]

Mike, nah not really. I haven't touched it much in the last month. I couldn't even look at the car for two weeks when my water pump belt slipped off and the car over heated. Ordered a new pulley and its running pretty good. Right now my main concern is getting it to pass inspection, then I'll look into fine tuning the maps and getting it to go fast. Right now its running 23psi with absolutely no timing but it still moves decent.

[Joey]

Need to get this thing in top shape! I want a ride

[a4spoolin]

Soon man. i mean the thing def moves but only prob half power that i want. The thing spots flames like no other

[Sideways]

It's sooooo biggg!

[a4spoolin]

i know, some chicks get scared.

anyway here are some test fitment pics of new intercooler

[Joey]

That is a big boy. Any fitment issues?

[03b6avant]

what intercooler? I needs bigger one and not sure the route to take. ER COMP, 034 B6 Big FMIC, TR11 or Garret 600hp core

[a4spoolin]

yea right now its kissing the hood when closed. the stock bumper will need to be destroyed inorder to fit. im hoping to pick up a s4 bumper sometime if i find one for sale.

this is the intercooler Front Mount Intercooler
rated at 600hp. dan runs one on his brothers bt b5. quality looks great idk when ill get it on the car but hopefully soon

[a4spoolin]

heres some two step action. only set to 4000rpm in this video

[03b6avant]

oh no shit thats the one he spoke of to me. I like that price. If it works for Dan then i'm sure i can make it work too.

[a4spoolin]

yea its a nice piece especially for that price. i cant wait to get it on my car. just need to redo my piping. gotta find something that can weld aluminium
