as above, ive priced up the quafe one from quafe direct, its for my 02J bov and it comes to £714 inc vat, then i will need the bolt kit at £136 inc vat, bit scary, just read about the obx ones have weak parts, i will be running around 300hp give or take a little.
Or if anyone knows a cheaper place to get a quafe on or a Peloquin from.
