so heres the question in full in case anything was misinterpreted i want to know if there will be a difference in power if i swap a d15b2 thats converted to mpfi by using imf, throttlebody, fuel rail, fuel pr, injectors. I also forget to mention i am comparing this to a d16a6. Also i imagine that they can't have identical power do to the fact that the d15 has a stroke of 84.5mm as opposed to the a6's stroke at 90mm. Just curious bc i have everything to do the swap and i was just curious if it was worth it. any way thanks alot for the help, and it it honestly appreciated.

 

It's definately worth the time and money. But how could it be more powerful than a D16A6? It can't. The D16A6 has a different cam and 100cc more! But definately Night and day for the the D15 from what I hear.

 

I think its definitly worth it, and you will be pretty close to the a6 (some people say you will put out around 105 or 104 at the fly wheel, I don't know, never seen any numbers)...

 

Worth it - yes.

more power - no. Yes, the A6 has more displacement, but if I'm not mistaken, the B2 has slightly more compression than the A6. It's not enough compression to compete with th edisplacement of the A6.
