so the rings in my last motor have gone and i think its time to upgrade... i wat to build a B18c* with stonger parts so i can put my old turbo on it... all signs point to the jdm type r however if in going to upgrade everything in the motor is it nessicary to buy a type r and are the blocks on all b18's the same? thanks guys
i have vtir b18c with T3/To4 Turbo running standard internal and 8.5psi, gearbox (oem non-LSD) and i put in Mfactory 4.7 final drive and 1.5way LSD and the gear ratio isnt that short like everyone thinks.
my turbo already making full boost at 4.5k rpm and stay 8.5psi all the way til 8.2k rpm.
so with the type R gearbox (close to 4.7 final drive) isnt that bad with the turbo b.
but i think you better off getting the b18c2 and get a good aftermarket LSD and boost.
cheaper that way, because if you run high boost, the oem type R LSD will not hold well, soon or later you need to upgrade your LSD.
and if you are going to rebuilt the engine with forged items, no point getting the type R, the b18c2 has better intake manifold (dual runners) gives you better mid-range, which helps spooling the turbo.
might as well do it right the first time.
