d15 build questions...
heyhey..
i have a d15b7 and ive decided to tinker with it... yes i know its a 1.5L but that makes it more fun..
anyways... im just wondering if any guys have done that and what they did to it (no turbo, nos... etc) im not looking for crazy gains just fun..
im currently putting in a z6 tranny, y8 intake manifold, b18b throtle body, y8 exhaust manifold...
just wondering if any guys out there are running the same setup and i just wanna hear your comments, suggestions, and frustrations that might potentially make things easier for me..
thx guys..

A head from one of the vtec d's will be a direct bolt on and be good for a nice little chunk of added power. I just picked up a z6 head w/65k miles on it with im but no solenoid for $120 shipped.

stuck in the same boat, z6 but with 160k miles..no selenoid or ecu..50 bucks though...cant beat it..
im building the z6 though..but
quick question..... is it worth it if i bolt the z6 head to my d15b7?? will i feel any gains??
thanks

Re: (RJwaggs)
yeah ive thought about putting on a vtec head but i not sure how that will effect the compression and other things being a 1.5.
not too many guys do what im doing so its kinda hard to find info..
i figure the more air i put in at a better flow rate the better ill be off... thats why i wanted the y8 I/M.

yeah ull feel gains but dont get too excited about it... u gotta get that air out too so ull need a better header... but like i wrote above.. im not sure how that effects the 1.5l engine...
my lack of knowlege tells me that the intake valves MIGHT have a higher lift? but im not sure of exact advantages of the z6 head on a d15..

umm i think the compression with the d15b7 with the z6 head on it will be around 9.2:1 or something but dont quote me on that...
thats what i was thinking as well the more air the better??? if i put this intake mani on will i have to replace the gasket as well???

yeah i have some bolt ons, not much but i have a shorty intake, 4-1 header, and 2.5 exhaust. so with that, will i notice an increase?? like honestly is it worth it to do the intake mani swap?
to be honest, you lost me with the whole "intake valves might have a higher lift".. but the z6 head on the b7 is a cheaper way for HP, i mean thats what bauley runs and he enjoys it and its a budget saver...

Re: (eg_srbin)
There's lots of info about mini-me buildups all over HT. Just search it up.
You can only gain so much with just bolt ons and the amount you paid for bolts is could be used to saving up and getting a turbo setup.
A lot of thought is needed in doing a mini me as with any other swap or mods. I suggest you start reading and figure out what you want with your setup and how much you're willing to spend.

true dat...

Re: (eg4usdm)
B7/z6 combo with a z6 headgasket will net you roughly 10.1:1 compression ratio.
You will need a y7/y8 stock cam gear or an adjustable one to get the cam timing correct or retard/advance your ignition timing.
to get the full gains of a mini me swap, get the p28 ecu, si/ex tranny, header, and intake manifold. You will also be needing to run premium grade gas but you can probably get away with using something lower.
doing an y8 intake manifold swap will help your engine breath better in the top end. the z6 intake manifold will help with bottom to mid range power.

Re: (eg_srbin)
so to get my question fully answered
i have a spare z6 head laying around... i need money and a block before i do anything to build it for boost.
since i have the z6 intake mani would it be worth the effort to bolt it on to my minor bolt on d15b7??

Re: (eg4usdm)
The DX intake manifold is camparibly smaller than the z6. All the parts are interchangeable and the swap will help your engine breath better. You will notice a gain in mid to top range.

Re: (eg4usdm)
hey can you like email me or something when u do it and let me know what it feels like in just a d15...? (yugo2k1@hotmail.com)
oh yeah .. u might wanna think about a bigger throtle body to get the air in.. i think a d15/16 is a 54mm.... i know that the b18b one is a 60mm...

Re: (eg_srbin)
The DX/EX/Si TBs are the same 54mm but I can't say for the CX/VX since I think they're smaller. If you move up to a B series/ H series TB, make sure you port match the intake manifold to get the effects of a bigger TB.
