Hmm, started to wonder that are u also going to use the std ARP bolts like Alex in his project?

Dunno where I read it from but I thought there was some kind of limit of boost(?) that the ARP bolts can hold and it wasn't that high really. If u are using them, how far u think u can go with them?

No, I'm gonna be running L19 head studs and a new Cometic Phuzion headgasket. I'm not as crazy as that Russian guy. :P

Well first I was gonna have Kris at KO build me one, but he said he was too busy at the moment and it would be a month+ before he could start it, and closer to 2-3 months until it would be done, and at the moment it was just something he wasn't sure if he had the time to tackle (still needs to finish No Shoe's setup). Then I talked with Full-Race, and they said they could make me one, but then they said they couldn't guarantee fitment of the 42r. And I don't mean whether it would hit the hood or radiator, I'm talkin they couldn't guarantee that it would clear the engine or slave cylinder/cylinder line. Then after I told them I wasn't willing to spend the $1300 plus shipping for something they couldn't guarantee fitment on, they told me that if I paid in full right now, they could tell me in a month or so if it would fit after they finished one of their customer's MR2 manifold who's putting on some other t4 flanged turbo, and if it did clear everything would take another 8 or so weeks to build mine.

I'm just pretty impatient when it comes to this kinda stuff... So as of yesterday, my buddy with that GT42 powered STI and I decided we are gonna tackle the manifold design ourselves. He's built a few manifolds, and we will be having one of our mutual friends who's got experience with inline 4 manifold design help also. Both are pretty good tig welders, and I feel have the experience to help me build a quality manifold. Maybe not KO or Full-Race quality, but it should turn out well, and I'll get tons of experience in the process. I plan on taking pics along the way if anyone is interested.

Like anyone would want to miss seeing those build pics Trevor...

Good luck with it anyway :) I personally would like to see some vids afterwards. You know...... for comparison....:twisted:

Plan on somewhere in the neighborhood of 40 psi.

And as far as build pics, I'll try to put some pics up as it progresses. Got tons more work ahead but I'm actually really looking forward to it! :D

i though about making my own mainfold but for my power goals i dont think it nessisary (400whp) and the fab work looked like it take too long. i might still do it later if i have some extra money and i get bored. i really like the look of the full race manifolds.

One of my buddies is friends with Cortney Green, a local guy who runs 9's in his 42r powered Civic hatch. He was telling me that a 2.0 liter Civic engine on the same turbo and almost the same turbine AR (I'm putting on a 1.01 AR, vs. a less common 1.05 AR they were running), hit full boost by 5800 rpm on the dyno (may be sooner on the street with more engine load). Not sure of the compression ratio that motor was though. So I'd say for my 2.2 setup with relatively low compression, it should be around the same, if not slightly better.

Well, as I said I was gonna do, Here are some better pics of my new turbo. Before I boxed up my old 35r, I took a few pics comparing it to the 42r...

Next pics will be of something cool, like a mocked up manifold, or a polished 42r compressor housing or something. :P
