Well, the previous owner had the cage done, but I think that he paid about 7k for cage and seam welding. Of course, he spend like 2 solid weeks prepping the chassis himself. You are probably looking at 5-7k just for the cage??

It kind of stuck.

Something about the inner machining and the heat transfer taking out the diaphram, ultimately the issue at LV RTA with FXMD cost them a motor.

Hi Mike,
Interesting...thanks for the info! There wouldn't happen to be a discussion about this posted somewhere would there??

Wow! That is some awesome info there. I had gotten a 44 before I knew the 38 came in v-band. I was kinda mad at myself for not seeing that the 38 was available in v-band, now Im happy

Not sure to be honest, I got the info from the guys at AFI turbo and was surprised. The owner actually machined out a couple of off the shelf Tial's to make it work for his setup if I recall the conversation correctly. He stated that it's an issue with manufacturing clearances that when extreme heat is at play leads to the diaphram contacting the surrounding CNC'd piece and ultimately failing.

The next day both Tial 38mm's failed in the way he had described to me on the FXMD NSX which ran enough boost to split the IC, Somehow they managed to fabricate a new section on their car with a 44mm in and tried to run the last timed session but the earlier 38's failing had already done the damage to the motor.

Wowzers, not very awesome for us grassroots fellas on a tight budget...that would be pretty devastating.

Cool man, I was just giving ya a hard time. Of course, now that all of us know you hold a PhD in some sort of engineering, we'll be scrutinizing your build much more critically! Can I get an amen?

EDIT: Per cooling stuff and radiator relocation, I think LIC is releasing (if not already released) a pretty trick radiator/oil cooler unit, so that might a little more cost effective than rerouting airflow and fluids to the rear of the car.

I was under the impression that the MVS can have water routed through it for cooling. Does anybody know more about this?

Yea I think Mikey from FXMD mentioned that to me, I have to imagine that's a little of a convoluted setup and certainly not something I would even entertain doing on a track car. I think his remark on it was "F%$k doing that, I'll revert to what I know works"

Haha true. If I remember correctly, those of us using a dump tube can use a 44mm as the inlet is the same size...providing there is enough room for the monster 44mm. I could be wrong though...

Hehe...there is nobody that is going to be more critical of the build than me Just ask Ed

Is there any info online about LIC's radiator/oil cooler system? Although I will probably stick with something custom from EQ as:
1) there is not as much space up from in the GC when compared with the GD
2) Kelly (EQ's fabrication guy) does extremely high quality work
3) I am already rerouting stuff to the rear of the car...like the Accusump and oil cooler. Relocating the radiator sounds fun, but when I think about it, perhaps not the best idea in the world! Running oil lines sounds a lot more doable than cooling lines. Kelly is pushing for a vmount setup with a rotated intake manifold...

That sounds logical. This is all I could find on the Radiator/Oil Cooler on the nets. There are actual pictures on the LIC motorsports facebook group/page

not sure if this link works:
