D16A1.

The 86-87 will be less of a pain-in-the-ass since it used a vacuum advance distributor and electrical system similar to the 84-87 Civic. They are easy to identify due to their brown valve cover.

 

ok now that i got the go fast part figured out..how bout brakes?? stock size and drilled rotors or oversized?? and what about the drum rears?? knowing that stopping is as important as going mach 90..

 

which is better for a turbo..the sohc or the dohc zc?..have found both in the similar horsepower range at jdm..

 

Convert to 86-89 Integra disc brakes. The fronts will be easy, since you will install them along with the engine swap.Civic/CRX blacktop ZC's and Civic/CRX/Integra SOHC ZC's will not directly bolt into your car. You need a Civic/CRX/Integra browntop ZC or 88-89 Integra blacktop ZC to bolt in. Importers do not adverise these engines, you have to special order them.

Stock SOHC EW/D engines are not practical to turbo due to their odd exhaust manifold flange, no one makes a turbo manifold for it that I know of (since HKS stopped in the early 90's.) Integra D16A1's and browntop ZC's will take a standard D-series turbo manifold, making them a much better choice. Radiator clearance may be a problem though, you may have to get creative.

 

Not true they can handle more if tuned right I know of many running over 10 including mine running at ten reliable.
