Guide updated.

I re-plumbed my coolant lines today. Originally I had them in parallel, but I changed them to series instead.

Have u had a chance to get your car on the dyno to check the numbers?? Even with your current tuning. Im curious to see what kinda numbers the kit puts out. Glad to see you've gone boosted for so long now with no major problems if at all

I haven't dynoed nor do I have plans to. PETERPOOP got 175/175 with meth injection on a manual, though. That should give you a rough idea. I'm glad I haven't had any major problems either lol.

At this point, the only issue I still have is some sort of boost leak. I can only hit about 5 psi if I'm flooring it, and once I hit that point I can hear the air escaping somewhere... I've suspected this for awhile but dunno how to proceed.

^ Lmao... That was the first thing I thought of as soon as I hit the post button. It's actually a pretty solid idea.

What happened to your downpipe? Did it break? It almost looks like it was cut.

Yup that happened to mine and that's when I went open downpipe. It was for me all the vibrations and the degree of the bend I had. Over time it broke.

The weld doesn't look like it had any penetration. Was this one a custom down pipe or is it part of the zage kit?

It broke at the weld - that's why it looks like a perfect cut. Pretty annoying

Anyhoo, planning on doing some professional tuning next week. I do still suspect a vacuum leak and would also like to do ignition timing.

Otherwise I'm trying to figure out where to go from here. I'm never going to raise the boost as I need this car to be somewhat reliable. Currently I'm thinking of actually switching to a top mount intercooler(+functional hood scoop) and maybe adding meth injection with like 75% water and 25% meth (since meth is just eh with only 8ish psi).

This down pipe is definitley repairable. You need to install a stainless mesh flex joint and have it welded in at a exhaust shop. I had one installed on my custom downpipe and never had a problem. Check the bottom of page six on my thread and there is a picture of the one I used. U can make a pressure tester to check 4boost leaks. My friend made one for his 932 hp e85 supra and found 4 boost leaks. Now he has much more torque and less lag. He used a piece of silicon hose attached to the turbo inlet that had a round piece of aluminum to block off the end. Then he installed a 3/8 air hose quick connect fitting by threading it into the aluminum block off plate. Then he used a compressor with a regulator set to 5 psi and charged the intake with the engine off. He then just listened for all the spots where the air leaked out. He could not believe all the leaks he found. He is running 32 psi of boost now with no leaks. He also said all the hose clamps with a T-bolt were leaking. Now he installed screw type hose clamps and they are holding good. Hope this helps.

On a second look U may need to have it rewelded at the crack because its on the bend. And have the flex joint installed on the strait portion of the pipe. U can buy flex joints that are only 3-4 inches long.

Weld it right back at the spot and the weld in some support bars. It wont break after that.

Thanks guys. I literally had it repaired an hour after I posted that up lol. Obviously it's going to be a temporary solution, and I'm especially worried about that other weld joint. Definitely liking the mesh flex joint though. Next time it breaks I'll have one added.

If I had a compressor I would definitely do leak testing... Anyone know of a place that rents em out? Otherwise, I'll just have a tuner look for leaks while we're tuning.

A compressor is a wonderful thing to invest in. I bought mine from Harbor Frieght about 6 years ago and is still compressing 235psi weekly. If you are able to get a hold of a compressor check this thread out to make your own 5 dollar boost leak tester:

DSM guys are awesome when it comes to help with turbo's for cheap. I made something like this for my crx. easy to use, easy to make

So last week I took the turbo out to check for shaft play since it's been in now for a little over a year. Also had to remove a broken stem from where the downpipe mounts up. Been putting this off for awhile because taking the turbo off this car is such a god damn burden lol.

Anyway, shaft play is just dandy which I was glad to see. I've also made some progress on my ongoing boost leak battle. I believe the problem is on the exhaust side - specifically where the manifold mounts up to the block. That broken stem wasn't exactly helping either. AND it turns out when I originally reclocked the turbo I had stretched the actuator and thus put preload on the spring (oops :p). When I get time I need to check it out more.
