Wow, what motivation

As far as the price that will have to be determined once it is complete. Should be in the $700 range with velocity stacks.

That is very nice looking and doesn't look thrown together at all. I would love to hear how this intake works out for the owner. I could really use one myself.

Ya, a before and after dyno would be cool to see. Then perhaps another dyno after tuning.

A similar intake was made by a buddy of mine, RBTALLY, and the setup made 586hp@wheels. There will be no before and after because the setup is custom from the get go. I am also fabricating him a custom Single turbo header from 321SS. The car will arrive at my shop next friday to begin fabrication. I will post pics as we progress. BTW, here is a pick of RBTALLY's setup. BTW, this RB swap is going into a 76 280Z Datsun. I also made him a custom intercooler for his setup.

The spinnings are from http://www.twminduction.com/ and are not listed on their site. You must ask for the 51mm Viper spinnings. The turbo is a Big Kahuna(p-trim .58) and flows 74lbs/min. The turbo going on this setup is also the Big Kahuna(p-trim .58). However, the header will be built so that a GT42R can be bolted on in the future once the race motor is built. Here is a picture of my GT42R slated for the 3RZ powered FC. It has a 5" inlet and 4" v-band discharge and is T4 flanged. This version flows 85lbs/min.

woow...look more like a t88...i have here a t3/to4e hybrid, with A/R 70 compressor. the compressor design is just like the one in the picture,but 4" inlet and 2.5" nonvband discharge. still a dwarf to that turbo.

as for the intake manifold, it's very tempting for me to fab one up using hte v-stacks and weld to the lower portion of the IM with a good size surge tank.
