hello chimchim, I'm an old %^*^*^^9#$#$^!!!!!!! HaHa. I have an "O" 1991 std hatch. 190k++ Yeah it eats oil but it is a spunky 'lil hard puller. Am I ready to give it up? NAW. I'm building an LS/Vtec to swap. The swap completion date is set no-later-than Turkey Day 2005.
Why so long? My prime objective is to be debt-free upon completion. Each move I make from now on will be $750 or higher. So I save and study the next move - looking for good moves.
I am using a B18C1 cylinder head. It is being machined right now. I am having a 3 angle valve seat job. Chamber hard lines removed and seats unshrouded. The port "bowls" are being worked. I do not believe in "hogging" out the port channels. Most all volumn effectiveness is acheived at the valve seat and chamber in the B18C1.
I did extensive work to the B18C1 intake manifold. I do not know what it would cost to complete my personal grinding/polishing (many hours). There were 2 machine shop functions performed. The throttle body was increased to 67mm opening down to a 65mm butterfly and matched to the intake chamber($150.00 shipped). The B18C1 intake manifold has secondary butterflies which open at high RPMs to provide "short fat air". I had a machine shop increase each butterfly diameter by 4mm ($250.00 bored/new armature/ oversized butterflies/ shipped). I increased and shaped all runner openings according to my personal opinions about each runner.
So? HaHa. Most builders would just buy a "TYPE R" style intake manifold and be done with it. I guess I'm too hard headed. I like the idea of 2 air stream styles in one manifold. All the racers complain about the secondary butterflies, not me, I'll just "give 'em one of deese and one of dems and YYYRRRUUUUUMMMPPPPHH yeah, that outta do it!!!" HAhaHA....HA.
I'm having a blast with my hatch. I hope you are enjoying your ride.
Anybody else?
