for less than the cost of a b you can make the d a 1.7L...put in a good valvetrain for high revs (>8k rpms)...slap a decent turbo on it w/ Hondata chip to govern the a/f, vtec crossover, rev limiter, and speed limiter(for OBD1 ecu...id go p28)
That would make a kick ass D series that, for the price, would probably be better than a turbo b series (factoring the cost of the engine, mods, and turbo (including hondata)
Now, thats not factoring the price of better internals, so youre still gonna max out at around 10psi...
At 10psi on a b18b, you damn well better be making around 200hp (idealy, using the formula of 7hp/psi...of course thats generous).
So say you get a really nice deal on the b18b (my personal preference becuause vtec is harder on a turbo engine...its already stress w/ boost/vtec, so adding more stuff is gonna make it worse...believe me or not, I dont give a rip...just think about it...) or even get one for a gift...now it makes more sense...or at least it sounds like a good deal. Put all that SAME amout of work done to the d and your 1.9L NONVTEC ls will smoke 9/10 d motors, as well as some of those domestics that hate on us (figure out which ones I mean)
However, back to the prices...say despite all that tuning (that you should be doing regularly on a boosted car) and all the fancy gizmo's and gauges...you blow your motor...the D is definately going to be MUCH cheaper to replace/fix. Just check out egay for proof....d16z6 for under $800...complete (that gives you a shit load of parts to use on your turbo d for this fix, as well as ones that may appear in the future)
Take the B and blow it...go check out prices...hmm, a lot more money...almost 33% more $ for b parts (yes 18b stuff will be cheaper...but their pistons are ass anyways...though the rods are nice)
If you have the funds...swap and boost are definately going to be better in the long run...hell the short run even more so (because theyre faster outta the box (even a b18b can keep up with a b16a2 W/ VTEC...for you vtec bitches...if driven properly...even beat it (off the line for sure)) Turbo D is a lot cheaper and definately more practical for the boost happy/cheap honda driver.
As soon as you start making your motor faster...its not as reliable. That "Honda reliability" that we always talk about goes right down the shitter as soon as our cars get fast.
If you want a faster than normal civic...that will be pretty decent, find a good deal on a b18c(1). It should be cheaper than a nicely built d...if it isnt cheaper, its a hell of a lot more reliable (IF you keep it stock...but thats easily more hp than you need for a daily driven fwd civic that weighs around a 2500lbs...or less if you bought a hatch
thats all I have to say on the topic
