(d15b7) I dont know what i can do to it. Should i do a swap or can i just swap heads or what / turbo /nitrous? what  

ITS ALL ON YOU. IF YOU WANNA START FROM THE BOTTOM UP AND HAVE AMORE UNDERSTANDING OF YOUR ENGINE OR DO THE WHOLE SWAP, TURBO AND NITROUS ALL AT ONCE AND HAVE HEADACHES LATER.  

I DID MY FIRST SWAP TWO MONTHS AGO. I GOT RID OFF THE "D"(DEAD WEIGHT) AND DROPPED A B18 NON VTEC. I CHOSE THE B18 CAUSE IS EASY TO WORK WITH, BETTER TOURQUE. I'M PUTTING IN A TURBO IN THE FUTURE ONCE I GET A NEW STROKER KIT, CAMS VALVES SPRINGS ETC.  

the D is a good motor, im pulling 130hp, red line at 7500rpms sohc, im my 91 hatch, i have a d15b8 block 1500(cc3) and a d16y8 vtec head. i wired the ecu and chipped it.
