Jumbo's custom turbo build

Gonna need more stickers.........=) I like the collection. Question, if a part goes south (and you really think it's a POS) does the sticker get pulled and banished?

I've never seen someone collect so much stuff at a show. How was the rest of the trip?

SEMA only added three stickers - I had the rest from you know - the parts I bought for my car. Some products didn't come with stickers so I decided to see how many of them I could get. Think I can do better next year if I make a list and actually try to hit them all.

Like how the iS sticker is first and on top.....

It was my first sticker! Stillen was the second. In fact, the entire first row is pretty much in order of my mods. The middle of the board sort of all came at once, lol.

So I haven't really talked about how the setup is aging, since it has only been about a year. There were some definite speed bumps along the way. Expensive speed bumps.

Fuel Injectors. This was not required but in keeping with the quality of the build, I wanted an upgrade. While the car was tuned and running fine with the OEM GTR injectors, the Haltech showed they were running at 85% capacity on the top end. On really hot days that could get much closer to 100% and I wanted more of a margin than that. Injector Dynamics 720cc with non-linear response. I ordered them with pigtails so we just soldered them into the harness rather than adding another connector.

Since the response is non-linear, the vacuum maps had to be adjusted. Now no matter how warm or cold it gets, I'll be in the sweet efficiency/capacity zone of the injectors now that they have been tuned during both summer and winter.

Oil catch. I'm finally happy with my current setup. I would have been happy with the last setup if it didn't breathe oil into the engine bay.

I blame it on the brass breathers and possibly the way the interior of the can was baffled. I went with what amounted to an unproven approach. It looked good for a lot of months but just didn't do the job. The new oil catch has perma-vacuum since it now plumbs into the cold side just behind the air filter and in front of the turbo inlet. Looks good and proven on other boosted VQ setups.

Stock ECU. After ruling out every other possible cause for a strange stutter in the rpm range, we finally discovered that the stock ECU had water damage. After running a lot of aftermarket wires through the factory firewall boot, it wasn't sealed properly. Water got in and the result was a new ECU + programming at the dealership.

Factory cross brace. During the custom install, the factory cross brace interfered with the hot side piping. Powerfab modified the brace to retain function.

Notice a mounting bracket attached to the exhaust. Right now that's causing vibrations at certain rpm ranges. For a very long time both the shop and myself thought it could be the turbo causing vibrations but last month we isolated the turbo and discovered it was not causing any noise at all.

The noise is no big deal - it's not that loud or anything. But it's an annoying little detail that I know about and plan to take care of. Been talking to the shop about removing that bracket, then adding another exhaust hanger in the trans tunnel. I want to use an OEM rubber isolation mount. Taking care of that intermittent vibration is about the last thing I can think to "fix" from the original build. Other than that the setup has been performing perfectly since I installed and reflashed the new stock ECU.

Last week at SEMA I talked to the lead engineer at Garrett for a while. He suggested I go to the GTX 37 for a bolt-on upgrade. Slightly better efficiency and range, giving me more on the top end. Bottom end won't notice too much of an improvement but it certainly won't suffer.

While that is something I might consider, I really want some WHEELS. Been banging this drum since joining the site - I just can't pull the trigger. I've had my eyes on the iForged Senekas for a looooong time. They look good on Panzer's FX although I would buy them staggered.

Also thought about a CF driveshaft. It's expensive but still less than half the cost of a set of wheels. It also removes about 50 lbs of rotating mass from the driveline and has an added fringe benefit of driveline shock dampening. Lighter wheels and CF driveshaft together should give me a nice bump in response.
 
So how about that drive shaft....?? In the fridge for now....?? I heard a story one breaking a while ago......don't know if it was from that company or not though.
Still something in my mind also,but have to leave that alone at this direct point for now. But still want to keep updated if you would pick this up ;-)
