I made that shirt from a D15B2 pic in a 88-91 Civic FSM
So I'd keep that engine, refresh it, then you looking for an extra 50hp. I/H/E might get you extra, a mild cam a bit more, then maybe pistons to raise the compression...
Or my personal favorite is a homemadeturbo setup. I've built a few cars on this, with junkyard turbos (had an Eclipse T25 on one, another with a Ford Probe RHB5) bolted to plumbing pipe I welded together (see: weld-el), run off a MAP and injectors for another car (Eclipse) piped through PVC and random radiator hoses. They would have been awesome on low boost, well one got ~40k miles!!! I just tried a *bit* too much boost for stock D15B2's (I guess I was excited :dunno: ). We were still pulling ~200whp, for ~$400 in parts
You're only looking at maybe a couple hundred bucks in parts to fix the small issues you have and a few hours of your time.
VS
$2k+ for a new drivetrain and the maintenance it's going to need anyways
I could see if maybe your trans blew or the engine popped a headgasket. But if your determining factor for swapping engines is b/c you have some oil and p/s leaks, I would strongly reconsider.
If I were to do a swap Id probably go with an H22, H23 VTEC, h22 head on my f23. Ths f20b is still good but for me it's not enough torque to make the swap worth my while.
Thanks for all the feedback Guys and talking sense into me. All very valid points.
I will focus on fixing the small issues the f23 has now and run it until it can't no more.
