Ive been reading about the VH45 more and more. I really like the idea of a V8 powered S chassis, and this seems to be a great choice.WDRacing wrote:But I also love the VH45 out of the Infiniti Q45. Since I can purchase an entire car for the price of the LS1 motor/tranny set. It's very light, has DOHC's and can be revved to 7800 easy with a simple valve spring swap.WD
Its biggest advantage over the LS1 is cost (like Brian said). Its all aluminum and from what Ive seen weighs about 500lbs with accessories. Add in the Z32 5spd (weight?) and youve got a nice combo. Slim's VH-TT powered Z32 has been running strong for about 3 years with stock internals.
The downside is the lack of aftermarket parts. Cams and forged pistons (if building up for major power) are hard if not impossible to find. But the heads flow pretty well and the VH forum mentions some off the shelf valve springs to help it rev higher. Mettler just custom fabbed a nice set of headers and I'm eager to see how they perform. And a few members from down under have fabbed up dual plenum intake manifolds. I'd love to try some ITB's on the VH. The early VHs (90-93) make over 300hp at the crank. I'd be satisfied with a nice 300whp with bolt ons.
I think the key here is finding a nice lightweight (aluminum) motor. The LS1 is a proven swap with great aftermarket. I wish there was an affordable 6 cylinder out there. The RWD VQ35 is too expensive and the FWD VQ's are a little too involved for me. I didnt realize the GM I5 was aluminum. That might be a great choice as I'm sure GM has sold plenty of them so they shouldnt cost an arm and a leg.
BTW, just noticed this forum. Excellent idea. +1 for NICO!
