Forced Induction on D13B?
So I have a 98 Civic Hx that I bought in 2015, I was just looking for a backup in case something were to happen to my primary vehicle. After testing out several cars without success I stumbled upon a 98 civic HX that had 136xxx miles. It was bone stock with Cold a/c and power steering, everything else was there, I test drove it and fell in love, it felt smooth and didn’t miss a beat, it was awkwardly kind of slow but i didn’t really care as fast wasn’t my interest.
Anyways, months down the road I start to investigate the motor, looking for stamps/codes etc. And I figure out the motor Has a D13B stamp on the block indicating it is a swap and not the original D16y5 it came with originally . I immediately looked it up on google and saw that it is kind of rare in America and didn’t find much info about it other than that it shares the same block as a D15B and bore at 75mm except the stroke is different at 76mm. Also the distributor is weird its a “Hitachi” type and the ecu is a rare obd1 lookingish 2 connection ecu coded “P2A”.
Since then i never drove it a whole lot but it served its purpose and I always did the oil changes and basic maintenance like plugs/wires.it’s now at 162xxx mi and pretty healthy, i once opened up the valve covers to see a pretty clean and healthy valve train, it looks like the motor couldn’t have more that 100xxx on it. It has a non VTEC head coded p2a-4 and the motor is mounted to an s40a000 tranny. Supposedly these motors are rated between 75-90hp but it feels like it’s got like 85-95 hp to me but just a guess. It has s*** torque but when it gets to 4900-5500k it starts to pull alright, I can drive it on the highway at 90mph 3900k all day no problem and can top out at 105-109mph when I need it to lol.
What would yalls thoughts be if I did a simple turbocharged induction on it?, not for a racing application but for economy and well s**** and giggles. My thoughts would be between 6-9psi. I know everyone says to d16y8 or B series swap it but I don’t want to go through all the trouble of removing the drivetrain and redo wiring etc, plus it feels kind of awkwardly weird owning a rare D series engine around here. Anybody have any ideas on what they would do with this particular motor if it was all you had? Would I need to at least go with forged pistons? I know they have those that will fit on this motor but I haven’t found any aftermarket connecting rods for this app. Or if anybody knows anything about these motors, how does the bottom end hold up?
