Re: Which motor to turbo better, z6, y7 or y8 (bmcc72)
i'm pretty sure the y8 has more of a dome shape in the head than the z6 which makes for less of a chance of detonation. i'll check on this when i get home but i'm pretty sure about it.

wait a min, can't i just use a y8 complete head instead of just changing the intakemanifold from the z6?

You can mix and match the parts from the D16Z6 and the D16y8 all you want. don't make a bit of difference exept for the compression. Use the Y8 manifold if ya can though b/c it holds more air than the Z6 one but if you don't have the Y8 then don't worry about it

for the price of a swap i can turbo a d16z6 and run just as fast if not faster.

You can use almost any combination of D-series parts and they will work...everyway will change your CR and hp.
Yes the B16A2 has a DOHC 1.6L
^^
Those numbers are the L # of every honda engine

well no ****, but what if he wants to exceed more then just a turbo sohc?
not so much potential there is it?

True, not much potential, probably about 300whp or so with racing rods or shot peening (spelling) your stock rods. But what the heck, it's still nice to see a 7psi SOHC handing a B16A or B18C1/5 their ***

Re: (B18C_DC2)
who needs more than 300 whp in a daily driver.???
d16z6 with pistons, rods, sleeves, and headwork is the same price as a b16, b18, or gsr swap. hmm which has more potential. a Dseries block that can handle 25-30psi or a bseries that can handle 10.??????
2000 and u can build one hell of a Dseries engine, and then another 3k and u got a nice turbo. and run 20psi daily average 10hp per PSI and your at over 300 hp. for 5 grand. hmm sounds good to me.

Re: (bmcc72)
wow, you guys are smart
but what if the b-series wants internals also?
what if he wants to exceed the 300whp?
b-series is your answer
even if you guys spit out all your facts on sohc power, nothing beats dohc

Re: (B18C_DC2)
I love B series motors. I just don't like them with a turbo b/c B series parts are so damn expensive and hard to come by. Me and my buddy picked up a D16Z6 two weeks ago for 75 bucks at a local junkyard. Yes it was a steal but they usually still go for around 250 or so. How much is a B series engine ( we're talking head and all ). Having a turbo on a honda can be dangerous, hence i prefer D series b/c of the low cost of replacing it.

Re: (B18C_DC2)
if a bseries wants internals forget about the 5000 dollor budget. thats all im saying. personaly i like bseres, with about 10:0:0 comp and a nice t3/t4 but who can afford the price of a Bseries buildup+turbokit+swap parts. youll be at about 10 grand. i mean who has 10 grand to put into a street car.? yes a Bseries would be nice but not for the money.
fast, reliable, cheap. i like the first 2. thats why i run dseries. fast reliable and cheaper than Bseries. 2000 and my car will run with a b16a, b18a/b, and a gsr. thats the price each of those motors cost, without the manditory swap parts.
anyways if your on a tight budget stick with a stock d16z6, with 10psi daily on a custom homemade kit. it can be done for under 2000 dollors, and u will have 160+whp. if u have a deeper pocket get turbopandas pistons/rods, and new bearings, headbolts, clutch and a cheap cam, and run 12-15psi daily. for under 3k. and have 200+whp

Re: (bmcc72)
i scraped my turbo kit all together for under 900 bucks. thats including everything you need, gauges, oil lines.....Have about 170whp. going to the dyno soon hopefully for a dyno day. will post results later for ya.
Anyways, i guess we've answered ur question for ya, stick with either the D16y8 or the D16Z6 and you'll be happy

Re: (lsvtec hatch05)
This topic is not supposed to encompass B Series engines.
This is not a debate on whether a B series engine is "better" than a boosted D series.
I did not see anywhere in this topic where the creator asked if he should do a B swap instead - did anyone else see that?
Bottom line is of course a B series has more potential, and no **** that if a B is boosted the same as a D it'll make a lot more power. The even more obvious thing though is that it also costs shitloads more to do a B swap and then boost it.
Not everyone has as much disposable income to blow on a boosted B series. Some people simply choose to not dump all of their money into their cars.
This topic is supposed to be about boosting a D series, so let's be courteous to the topic's originator and leave the B series stuff out unless he specifically asks for it.
If anyone wants to go toe to toe about boosted D series vs. B series N/A or boosted then someone can always create another topic.

Re: (B18C5-EH2)
Agreed. Shut up about b-series, I wish I had one but I don't.
Anyway, what type of engine management are you boosted d series guys running. I hear a lot of people using the AEM EMS, but thats pretty pricey. I'm tryingt to peice together my system on paper right now, hoping to do this whole thing for > $1k.

Re: (jolt-tsp)
how much boost are u running? 10psi tops get some dsm 390 or 450cc injectors, resistor box, and vafc. very reliable and any dyno place can tune it.
if u want more get urberdata and a cheap laptop, then get a friend that can soder.
AEM EMS way to expencive. also hondata is way to expencive especialy if u want to be able to tune it. if u have a local hondata dealer with a dyno then hondata is pointless without the fully tunable version.
im currently running 7.5psi on dsm450s and a vafc on a non vtec d15b. would be 10psi but my clutch is gone and i need it to last till spring.
the dsm 450s are almost to much. i can;t lean idle out enough still blows out black smoke.
but a nice set of automatic dsm 390s would be perfect. for up to about 12psi. no fuel pumps needed. with the 450s i supose u could drop your idle fuel pressure but i no nothing of how dangerouse that could be.

i belive you could use an afc hack or hondata to tune your ecu to work out the lean burn..
someone correct me if i'm wrong.

urberdata. that's what i'll be using for my project. i got all the kit under 12k. Hopely i'll get all the part by this week so i can install them this weekend.
So if you want to boost about 20psi what internals do i need to get?
rods
pistons
resleeving
bearings
am i missing anything?

lower compression
to boost more than 12psi i recomend.
forged pistons, forged rods, new bearings, nea gaskests, and a copper headgasket.
also u will need a good engine managment and 3bar map sensor. also turbopands rod/piston combo would work too.
