Couple of random noob questions

[xxxbigirishxxx]

Hi all! I'm new to the DSM scene, and have undoubtably bought a project that is over my head, at least for the time being....but I'm working on coming up to speed on DSM's. I've been spending the last few weeks browsing articles on your forum to glean as much info as I can on this beast, and I've got a couple of quick noob questions that I can't seem to find definitave answers to.

1. The car that I bought is not running. It was timed improperly and bent all eight of the intake valves. I've pulled the VC to see what's going on, and I have a question about the valve springs. The guy I bought this off of got it from another guy and blah blah, he knew nothing about it. When I looked at the springs, they appear to have a second set of springs inside of the main spring. This in not factory, correct? also, the retainers are deffinately shiny stainless, so I assume these are not factory either. Correct?

2. The car had a FMIC with long route piping. I'm in the process of changing this, and my other question is about turbo piping. The turbo on the car is a FP GREEN. The outlet is plus or minus 1 1/2 inches, and he had a pipe roughly the same size ran for about 2 feet out of the turbo. Is this desireable, or should I jump the pipe size up as quickly as possible after exiting the turbo? The FMIC has 2 1/2 inlet and outlet, and I have 3" piping available. It's easier to route the smaller piping, but I want to do this right.

Thanks in advance for any and all help, and I look forward to becoming a contributing member of this forum!

1. True aftermarket, brand unknown so up to you. Retainers are more than likely titanium, not steel.
2. I want to say stay with the 2 1/2 piping, when your ic exits are 2 1/2 that is your choke point in a 3" system, and would be pointless.

Thanks!

A quick note on the valve springs. They have red paint on one side of them, and I've seen pictures of Brian Crower springs with the same paint. Safe to say that is what I'm looking at?

Also, on the piping...he actually had 1 1/2" diameter piping for the first 2 feet and then jumped up to 3". Is it O.K. to leave the 1 1/2" piping for a few feet, or should I jump it up to 2 1/2" sooner? Thanks!

On the tube coming out of the turbo compressor. As long as it is larger than the compressor outlet it is fine just don't go Large/Small/Large. Small/Large/Large is Let me guess, used the smaller pipe to run past the fans.

Yep, you got it. He used that to run past the fans, and to be honest, I'd like to do the same thing in the opposite direction...just wanted to make sure that it would work O.K. Thanks again for your help!
