im currently running the 15g on my d16y8 and was thinking of building the d15b7 and throwing my kit on that. is this a good idea and have any of you guys done this, if so what kinda numbers you throwing down? thanks

 

thanks guys for the input

 

why would you take the kit off of your y8 and put it on a d15b7 ?

 

well i heard they are not an bad engine for boost.

 

hmm lets see.....the 1.6l vtec engine with much thicker rods vs. the 1.5l non vtec engine with toothpick sized rods...which one sounds better for making power? Yes boosting a d15b7 would be fun and all, but you would be a fool to swap out the better d series motor that you already have for a b7.

 

Much thicker? You've got to be kidding. D16 rods can maybe handle 10-20 more hp than a D15, so I wouldnt say much thicker. He is right about the y8 being a much better motor though, the only reason you should ever boost a b7 is if it is already in your car.

ok i know they aren't that much thicker, but like you said you would have to be an idiot to swap out a y8 thats already in your car for a b7.

 

ok first off, YES the Y8 rods have been seen handling 250-300 wheel power where as the D15 have been seen handling 220 just before snapping into several peices and trashing the motor.... There is a BIG diffrence in the rod size and overall strength. a few thousandths will make a big difference so don't kid yourself. also the larger bore will let the motor BREATH WAY better thus allowing for better boost responce and more power to be gained. The V-tec head outflows ANY non-vtec head hands down. The runners and ports alone make a hugh difference not to mention quenching is beter as well.

you do as you wish and keep thinking the D15 is better, but i can assure you as plain as day, that you will not be as happy with your D15 as the guy with a D16 V-tec will be.
Also FYI performance rods for D15 cost 3x's that of a D16 due to rod length is different and demand is way low.. yes the stroke is shorter on a D15 as well. Think about it, thinner rod and shorter stroke. (no not talking about your ****** there pal ) that makes for a bad combo when it comes to performance.

stick with the V-tec motor and rest assure you'llbe way better off in the long run.

 

i say learn on the d15b7, if it blows no big deal. the just through in a z6 or y8. its a great motor for learning on because they have no resale value.

 

swap the d15 in and low boost on that..... WHILE you build up the y8 for high boost.

 

^^^that is what you should do. why would you want to swap in a1.5 non vtec in place of a 1.6 vtec???? it seems like you should of been able to answer your own question.

 

Talk to Dustin(Bauleycivic).. He is boosting a b7 engine and has for a while now..
