Re:B20/Vtec or H22a?
H22A requires hybrid parts to fit on the shorter bodies (civics). They have a lot of problems with snapping the axles. But if you can find stronger ones, it would be well worth it IMO.
If you're going to be building, then forget what factory statistics are and look at what you'll end up with for X amount of money.
I decided to stay away from B-series and stick to build a Z6 motor, mostly for some originality (how many people are pushing 22 psi on their EX motors lol).
My biggest downside is that the engine heads on D-series don't flow as well as B-series. I don't care about the weak factory D rods, because i'll be replacing them, as well as pistons, sleeves, etc...
I don't plan on boring, just leaving dimensions factory and getting compression down to 8.5:1.
D16Z6s comparitvely to B-series are incredibly slow, but way I figure it you drop the compression of a b16a3 to 8.5:1 and its only going to be fractionally higher then a z6 with same compression (yes, it will have better flow and make more noise).
Just some additional things to consider:
1) how much money do you want to invest?
2) when do you want to have the car completed?
3) are you still learning about cars?
4) what other money grobbing factors are in your life (college, health insurance, rent, house payments, car payments, house insurance, wife)?
For me I realized that building a car while I'm doing part time work is a much better idea and doing it very slowly over the course of 2-4 years. This way when i'm done, I will have a more reliable, stronger, and fun ride.
I know I'm going to recieve criticism, because most people on here are just slapping what they've got together, boosting it and blowing it.
I'm sure jeff would agree with me, that doing things in haste with cars, ***** you in the long run.

Just kidding man... It really up to you mike... You can make any car fast as long as you have the ends to back it up. From personal experiences H22a is damn fast in a hatch. And it requires alot of attention. Just like many of the motors out there. And i also driven B20 turbo that feels as fast. The choice is really up to you. If you are an all motor kind of guy or turbocharged.
BTW, how's the 450 cc injectors hunt goes for you? Hard to find it huh? Or did you even look?

sorry man, yeah I just dumped $2200 into this semester of school.
I'd say just take your time with it, I know you're probably like me (I want 22 psi now!!!) but without being practical you just end up with broken rods.
