I must be the only one who knew the differences? Whew and all these experts out here!?...ha,ha.... First of all I don't recommend this swap but on the chance you can't help yourself, these are differences, exterior and phisically. First there is a Blue Valve cover, most obvious (generation hence, 92-95 or 96-00 generations do not differ)not sure when the first "type S" engines were first brought into production , I would not guess prior to 1995. Anyhow the Intake Manifold will not retain the 2 stage plenum, like the US/ JDM spec H22a or H23, it appears similar to B18 Type R. Physical demensions are same. Now It is quit easy to convert a JDM H22a to these specs, simply change the cams and plenum and T/B. Even w/ the Type R series Plants, there is always room for improvement. Now perhaps w/ my limited knowledge of this engine, it may also have attributes similar to the B18C5 as well, such as mild porting from Honda and a tighter valve spring configuration? Static Compression of pistons may also be a tad higher as well, but that is minimal as is the Coatings on the pistons.
Before I'm crusified here w/ the Prelude or H series Junkies, It is my findings and experience ( well qualified, mind you), that the H or F series swaps don't do the lighter inequiped Civic chassis any justice. For a drag application this is great, but for street not a good combo. For example the H series engine alone outweights the B series by a stout appr. 75-90lbs, and the trans another 50 or so lbs... hence 125+ lbs of additional weight hanging over the front of the car. Besides the factory brakes not being up to par for the added tonage, the factory suspension also is ill equiped. Even w/ lowering springs , i.e. Eibach,Intrax,etc... are progressive design and developed to handle the factory engines weight and bias it accordingly. Furthermore the factory equiped toothpick size swaybars are way overloaded when abrupt turns are made.... In conclusion besides the wonderful torque figures the big engines make, without proper well developed suspension, transmisson suitable (lsd equiped) and tires, the car will not get very far just roasting tires ( a billowing smoke cloud never won a race!)! The B series are lighter combos and generate A usable and manageable amount of torque and can generate as much if not more peak HP! Stick with what works. thanx for your time.
