i've changed my mind from h22a swap to boosted sohc. now, i have searched and found that aftermarket internal parts for d15b is rare, is this true? i like d15b since it already has a vtec and the price of the engine is dirt cheap. the thing is i want to build the internal to make it reliable for long drives across states. where can i find the parts like forged pistons and rods for d15b. thanks dudes
