curtis, with the BW stuff, you are either limited to the poor design of the Bullzeye bolt on hot side, or spending a lot of cash for a good T3/T4 manifold. The initial price is appealing, but then you end up running into other issues and expenses.
This argument has taken place many times, and usually, there is no convincing either party that they are wrong. Even Ron Shearer says the Garrett turbos are a lot more durable than the BW stuff.
The FP stuff fits like a glove, even on the VR4. It's been done for years, there is no guessing, it all works like it should.
He will be able to bolt on his HTA68 in place of his stock turbo with an all around great performer, for less than a grand. The BW stuff is going to cost more than that, no matter which way you attempt to set one up.
The BW stuff does have its place, but it all goes back to the "keep it stupid simple." The FP stuff works great and they are always upping the ante with their billet wheels and new bastardized combinations.
