Love this build.

What type of turbo you looking at? GTX42, S480?

Am I the only one whose disappointed he doesn't want to spend the extra $5K or so to get a new e-shaft and follow the original build plan?

He'll spend at least that much going fi . I believe the hype train has a lot to do with it. You're not "baller" without big turbo and big numbers. I personally enjoy hanging around him when I can and I'm disappointed he's not staying na also. I believe the car, if completed, will be overpowered and no longer an enjoyment to drive. I don't want to throw shade at him because I'd like to go 20b as well, feel mid to high 400hp would be the cars sweet spot.

it will probably sit at about 600WHP with the street tune, with traction control, and a 370z transmission. Should be very derivable. Actually, The turbo should be about the same price, but my issue is that once you start spending in the range that a turbo costs for an NA, price per HP gets more and more not worth it. Had that shaft run out well, it would have been a nice setup at a reasonable price. It's no longer a reasonable price for an NA, at least not for the budget that I set aside for the build.Have to also consider that it would going to cost me another 3~4k for the independent ITB setup on the semi pports. In all actually, the turbo build as it is now will actually come out a little less than the original NA price. Adding another 6k to that could have been aluminum housings.... its just too much extra for me to continue that route.

I'll save the NA build for an all aluminum build where I can save weight too. Right now, I just want this car done for DGRR.

Carbon zylon roof for the car. Pictures dont do it justice. Metalic bronze. I'll add some pictures once its installed.

Pictures really don't do this roof justice. It's pretty awesome. Now to find someone that will do the rest of the bodywork I need.....

Does that go over the top of the roof, or do you have to remove the roof in order to install it?

It's a complete roof. The factory roof's tack welds are cut, then this is glued and riveted in. I had it installed to BMW / Porsche / Audi standards by a guy certified by them.

It's a 5lb roof. Factory panel is 20lb.

Looks great. Some day I may start trying to lighten things up on my car a bit. Its probably the heaviest rx8 ever.

Can you post pictures of the install process (if you have them)?
