I went from making 15psi at 4200rpm to 15psi at 3200rpm, lol. It also doesn't drop torque anymore as the RPM climbs.

I ran the car at 15psi two nights ago and it was SERIOUSLY ******* fast. Its like a different motor with 4 more psi. I don't see why people consider buying anything else.

Oh, and now I'm up to 14-hours of seat time on Tim's parts with no failure.

I'm loving all this praise from going cast to tubular. I can't wait to get mine running

How many people does this make now that have switched their mani/dp combos in the last year?

In for before and after numbers!

Phew. Got distracted by the news this morning so didn't get to work til much later than I had planned but here is where I stand now. All that is left is to weld it! It lines up with the head flange near perfectly. I'll need to grind just a hair of overhanging metal from the inside of runners 2 and 3. As it sits i'm happy with where it puts the turbo in the engine bay and very happy with the way everything lines up. I dont have enough gas to weld it today though unfortunately and the store is already closed :(

I wanted to use every last bit of gas I had before getting a new bottle so I actually got some welding done yesterday afternoon. Going to get more done today and get it tacked onto the head flange to start the downpipe. I have to finish this stuff so I can put my car back together because I need it this weekend.

I lent my jack to a friend 100 miles away and was doomed to scissor jack usage to get the car on stands in order to begin the DP build. One look at the scissor jack and I had an idea.

Scissor me timbers!

I welded a socket to the jack and use the impact to raise the car! Its better than a floor jack!

Edit: and I forgot to post up the pic of the beginnings of the downpipe. The DP will be done tomorrow.

Me too, I wish I could be there :(

So i've got a couple of questions. Phil wants the downpipe to extend past where the stock cat is but I haven't had a cat or a stock exhaust in my car for quite some time. Can anyone give me a reference point under the car (on a 1.6) as to the location of the cat so I can extend the downpipe to that point?

Also, Phil where is your WB02 located? I can put the bung where is convenient. I have mine hanging down from the shifter turret but it just has enough slack in the harness to plug into only one spot on the downpipe. Not sure if yours is near that or in the same place.
