I really don't know what HP I will acheive. 67mm throttle body flows into the B18C1 dual intake runners. The dual runners are kept but both re-shaped and bored out. 310cc injectors flow into a ported/ bowled/ seated/ unshrouded/ butterflied HAHAHA B18C1 cylinder head. The type R camshafts and valve train are coupled with adj. camgears.
This cyl head setup is coupled with forged pistons (10.5 - 11/1) on eagle rods pumping in a B18A1 std block. Water/oil pumps/timing belt are rated for VTEC.The crank is slightly shaved and lightened a pound. A Main girdle/ 19lb flywheel (standard B18)/ and fluidampr crank pulley will settle the harmonics. These items will help the B18A1 block to rev a little higher.
The engine will stay natural. The exhuast escapes using a long pipe 4 to 1 header with a 2.5" collector. To increase the velocity I should reduce to a 2.25" cat. And then reduce again after the cat? Or wait until after the cat?
What is the theory ? the farther from the manifold I reduce then the relative effect in the powerband is???? Any ideas? Should I just hand it over to Hy-Tech and be done with it?? JHAjHAJhaHAHA!!!!!!!!
