I've got a 88 CRX HF with D15B6?, D16Y7 block, a D15 V-tec Motor, and two Z6 Heads.. I've also got a T3 turbo and I know I can use my log manifold off my HF motor in my car and make an adapter plate to mount that.. But what I was wondering is what setup would be fun to drive easy to maintain and not to bad on gas mileage, cause I'm gonna have to use the car to get back and fourth to school in orlando, I live in tampa, it's probably around 90-120 miles a day lol I'll be using my HF tranny btw and was also wondering cause I got like 3 ecu's and not sure what to look for on the sticker to know what's V-tec and what's not thanks guys

well I'm not looking for better gas mileage with my d15b6 I get 47 with ac in town and around 50 on highway if I'm not fooling around lol but I kinda don't wanna drop below 35-40 and I want it to be quick-ish and fun to drive 0-60 in 11seconds gets boring after awhile

There are alot of combo's you could do with those parts... if you wanted to use Vtec and turbo (good combo), you could use the y7 block and the z6 head.. would have to use a dual oil line to feed the turbo and the vtec solenoid.
You could use the b6 block, and the z6 head, also ok, but I'm pretty sure the parts in the y7 are stronger.
The D15B complete motor that you have is more HP than your HF is... HF I believe had 71 hp... something like that. And if I remember correctly, you find an ECU for that motor, you've got 3 stages of Vtec to shift through.
In fact, if you're looking to keep decent gas mileage, but you want better acceleration, you could go with the D15B alone... push about 3-5 PSI boost to it from the T3 with a decent boost controller, and your accel picks up even more... good possibility with that setup that under normal driving conditions, you'll be getting close to the same if not better MPG than you are now.
D15B w/ log manifold, billet aluminum adapter plate, T3, decent FMI (You can get a front mount from ebay for like.... 30-50 bux, if you don't want anything huge... but you don't wanna run the turbo w/o one. Too Much Heat IMO) $20 boost controller from Ebay (alot of ppl are going to be angry with me for this... but a boost controller is nothing more than an adjustable valve... the more you pay, the more you're wasting.) And the factory BOV would be perfectly fine.
Remember tho, before you boost it, build it. If you had anything at all wrong with that D15B before, even a little bit of boost will make it painfully obvious in a couple weeks. A stock rebuild of rings, seals, etc. will be plenty for under 6 PSI.
Hope all that helps, my fingers hurt now, and I need a cigarette.
(BTW, I set up the Y7 block w/B2 head and A6 cam/intake that my friend is running right now... 0-60 isn't 11 seconds... 1/4 mile is around 14, no official time yet. And that's 4PSI max, on a basically stock engine. Before we swapped it, he was getting 34 MPG avg. now it's more like 41 MPG... never turns the boost off either.)
