Change Engine Head Good Idea?

hi i have a civic 91 sedan eg and my engine is a d15b7 carbby, my idea is just to change the head(block) to a d15b vtec or a d16 is dis a good idea because i only have a budget of AU$1000.thx for future answers


PS. Is der a d15b vtec carbby??Kinda lost on dat one

I think you have the wrong engine code, the 91 LX came with a D15B2 which is a DPFI motor and most novice mechanics mistake it for a carburated engine. But this motor is fuel injected. The d15B7 was in the 92-95 civic LX. Your options are endless really, you can swap in a d16z6 or a d16y8 if you want to keep it SOHC. Or you can go DOHC with any B series motors. The B18A1,B18B1,B20B, and B20Z will work and are non-vtec. The B16A1,B18C1,B18C5,B18C and B17A are all vtec motors. Do some searches on swaps with the motors and you will get loads of information.

NO! not good,save money for something bigger than d-series.

opps i made a mistake its a d14b4 not a 7.and yes it is carburetted.and i ask already for a d16z 6 and the guys quoted me on $2200 for a swap.Only reason y its that much coz its included labour coz im not really a real mechanic.if anyone out der a mechanic and wants to help sms me and i can pay for ur labour but not a $1k labour ^^

Ahh you have the D15B4 and let me guess you don't live in the states?

I would just do a few upgrades to that motor honestly. You can get the basic I/H/E (Intake, Header, Exhaust) and then swap in the cam from a SOHC ZC motor they are rated at 127hp and the motor you have is rated at 105 hp.
To be completely honest with you with $2,200 you could make the car a lot faster with some mods to your current motor. For that kind of money you could rebuild the motor with some higher compression pistons and get a aftermarket camshaft, the should put you in the 140+ range after it is tuned. The D16Z6 only has 125hp.Food for thought. ;)
