Yeah I also like that idea, but I am sure you have to push the shit out of a 35r to make that power. There is not many people with 700hp 35r that will last a while. As far as I know I mean prove me wrong with info. I havent really looked too hard in the 35r fame.
Also whats the cheapest 35r that will make 650hp for under 1250$
The HTA's need lots of boost to make big power, but they can take it, lots of EVO guys are making BIG numbers with them. A GT4088 is gonna cost just as much as a 35R HTA unless you plan on running journal bearing, and then kiss any chance of decent boost goodbye, because even a BB version of that turbo will be lucky to see full boost by low 5's on a 2.0 liter. The 35R HTA will spool 1,000rpm's sooner and support damn near just as much power--seems like a clear winner here.
A normal off-the-shelf 35R can be had for $1,200 and you can go pretty damn far with that. You won't hit 700whp with it, but low 600's should be easily attainable.
