i have a d16y8 engine in my civic...would i be able to take a b16a1 head and bolt it on my block....would it fit and will it match up right?

 

Welcome to the forum,this may help you D16Z6, D16Y8, D15B7: If you have one of the lower and cheaper civic models, IE The Cx, Dx, Lx and If you're looking for a cheap power increase while still maintaining stock gas mileage then the possibility of swapping in one of the higher model civic engines is right up your alley. The D16Z6 is the SOHC 5th Gen. Si and Ex engine pushing 125hp @ 6600 rpm and 106 lb.-ft of torque @ 5200 rpm. The D16Y8 is the 6th gen. SOHC Ex engine pushing 127hp @ 6600 rpm and 107 lb.-ft of torque @ 5500 rpm. These are extremely easy to find since allot ppl swap them out in favor for more expensive engines. They bolt in like stock and the whole package could be had for hundreds (You might even find someone who’s recently swapped who would basically give away their engine). Let's say you want something cheap but you could work on for possibly turbo or nitrous? The D16Y8 is cheap and the pistons are the exact size of TT Supra pistons. They could substitute for forged versions and work just as well for a turbo upgrade. Be warned though as the D16Y8 has a particularly bad Rod to Stroke ratio at 1.52. I also suggest the B15B7 which is the 5th gen. Dx and Lx engine pushing 102hp @ 5900 rpm and 98 lb.-ft of torque @ 5000 rpm. If you have a 5th gen. Cx and you’re in need of the cheapest upgrade, this motor could be for you. Again you could probably find it for less than $500.

B16A1, B16A2, B16A3: If you need a little more power and have the money, the Civic Si and the del Sol VTEC engine are possibilities. They are all DOHC 1.6 liter engines pushing 160 hp @ 7600 rpm and 111lb.-ft of torque @ 7000 rpm. The A1 is the pre-obd engine that came with a cable transmission and various other pre 5th gen. items that need to be dealt with when considering the swap. The reason I point this out is because all 5th and 6th gen. civics came with hydraulic tranny's so think twice about this one. The upside is the cheap price. The A3 is the OBD1 engine out of the del Sol Vtec. These older models can be had for cheaper than OBD2 models and have upgraded various things such as hydro trannies. These are a perfect choice for the 5th genners. The A2 is the 99-00 Si engine. Same as the A3 only this one came with an upgraded OBD2 emissions system that is mandatory for all 96+ civic swappers. The B16A1 could be had for around $1200. The B16A3 could be found for about $2000-$2500 and the newer B16A2 could be found for around $2500-$3000.

Good luck ,Bobby
