You do not need the block.

If you do the VTEC head and expect VTEC, then wiring harness and ECU will be necessary.

If you wanna do it for a bit more compression 9.1:1 to 10:1, then all you need is the bare head, use back the stock valvetrain, cam, ecu etc. Oh yeah! Use the VTEC Intake Manifold for additional ponies as well.

Good gains for cheap.

vtec conversion

Postby Hirotoshi » April 3rd, 2008, 9:38 am

what your talking about is a mimi-me conversion, you need the 92-95 vtec head,96-00 vti intake manifold and fuel injectors 240cc,timing belt,correct ecu(auto / manual) i would recommend you get a set of pm3 flat top or p29 dome pistons to increase compression,stock 96-00 exhaust manifold.this set-up i gurantee will give you a lot of fun $ trills. :D

hey man i can get u the full conversion which includes engine (d15b vtec) with s20geabox:) harness, computer even the whole subframe cya remember how much d man was calin 4 it ill let u kno.. but if i was u i wud just do a manual conversion assuming ur auto get the intake manifold from a d15bvtec, get a air fuel controller get ur ecu chipped according to the size injectors u runnin and goo boost ull have alot of fun with ur motor once its tuned proper these engines can make very impressive numbers on the dyno and be reliable. and afta if u blow it up jus buy a b series :)..just my input eh u can get a good price on turbo kits on ebay (kno wat ur lookin 4 tho) and mi boy in foregin sockets and chips ecus (alot of hondas) for like 70us the only problem will be to get it across there..bless

Question: would it be cheaper to buy a complete engine?

for your education,a mimi-me is the conversion of a non-vtec d series engine to vtec,by putting a vtec cylinder head on a non-vtec block. it does not matter if it,s a d15b or a d16z,d16y. :lol: reixmann, i guess you won,t know what an ls vtec engine is either ? :P

not quite correct but i acknowledge my error

Mini-Me

One of the most popular and effective methods of achieving greater power from a D-series motor is replacing the cylinder head with one from a more powerful D-series motor. This is usually done between D16A6 and D16Z6 or D16Y7 and D16Y8 engines, however, can be performed in other combinations as well; such as a D16Z6 head on a D16Y7 or D15B2/B7 block. The Z6 and Y8 heads are VTEC (Variable Valve Timing and Lift Electronic Control) equipped, and increase horsepower significantly over stock levels. This operation is known as a "Mini Me" or partial swap. Mini Me's are popular because they offer a substantial performance upgrade by adding VTEC to the motor at a relatively low cost. Simply adding a VTEC head to a non-VTEC block will not increase horsepower alone. This is because the VTEC circuit must be activated and accompanied by a new 'high cam' fuel map from the car's ECU.

u mite b suprised sum places have engines with very low mileage on dem an plus u supposed to get a lil warranty not to much time tho jus enough to do ur compression and other inspections on it..but go ahead with the mini me. it wud be good gains for cheap.

Would a single vtec head work on a non vtec block? D15b head an a d15b block changing the harness an brain as well. Would I have to do any mods to the block?
