Mini me turbo?

[trace01m]

I have a z6 head on the way, and I have the y8 intake manifol and TB. Everything is gonna get ported before it goes on the car, and I'm thinking I need to get a better cam.

What I need to know id how much boost can I hit the d15b block with before bad things happen? If I have to I'll take it to ApexR to get it tuned, but I'm hoping to be able to run 8-10 pounds without killing it. For about a year anyway.

First of all, its HP that kills motors, so your question should be how much HP can the block take. We cant tell you how much psi you can boost if you dont tell us what turbo you want to run. Also, you need to get it tuned no matter what. Run 10 psi on a basemap for a year with any turbo and I wouldnt be surprised if your motor blew.

Ok, then how much HP can I get out of the stock bottom end before I'm swallowing a piston that comes through the firewall?

its all about tuning. u can put a hole through any block, built or not. tuning is what it comes down to. depending on how good the tune is that;ll be the deciding factor wether u blow it or not. also why u want to cruise around on the highest setting all day.

I just want to have one setting and not mess with it. I don't want to mess with changing it cuz it's my daily driver, too, and I will have my kids in it with me a lot, too. I just don't want to be the guy with the slow ass sedan anymore! I know it isn't going to be the fastest, but I want some more Oomph!

d15b what?

 

[jason_guy_yeah]

I think the best thing to do is get yourself a t3/4oe kit and have a tunner do it, tell him it's all stock. Maybe get a s200(hondata). Unless anybody else has any better ideas.

but first he has to ask nate if he can tune it. (ill ask him when i go in there on monday)

cool, if he has a labtop with windows ie...xp, 2000...and a a/f reader of some sort. He and a friend could tune it themself for the expereince. with a s200 or s300 hondata

if its the jdm d15b like i got DONT throw a z6 head on it cause it will throw yer compression up to like 10.6:1-10.7:1

d15b-flat top pistions, bigger cc
z6-ditched pistons, smaller cc

so if you do tht combo you get flat top pistons with a smaller cc so just boost the d15b as a whole since it does have the p28 rods and has like 9.5:1 anyways. and the d15b head is a z6 head with a lil bit better flow and tiny bit better cam. thts if you were talkin about the d15b as you stated. cause you'll be makin a time bomb if u boost that mini-me combo lol

compression doesn;t matter.. to a degree

what the hell are you spewing?? please, if you dont know what you are talking about, DONT POST!!!

compression WILL NOT bump up if he has the jdm d15b vtec. the d15b vtec head DOES NOT flow better than the z6.

the heads are the SAME CASTING, therefore the will flow exactly the same. putting an identical head on a motor thats 9.2:1 will yield the SAME COMPRESSION, not bump it. pistons dont mean s**t, because the heads are IDENTICAL!! how could it possibly bump compression??

d15b what?

Mine is the D15b2 that came stock USDM in the LX with DPFI.

t3/4oe? Like original equipment from something? Sorry, I don't know a whole lot about the types of turbos. I just know general knowledge about workings, efficiency, and things like that.

he wrote that wrong. its t3/t04e and its a type of turbo made by garrett.

and compression definetely DOES matter

Oh, ok. Grassy ass

what do you mean pistons can't affect compression..... low compression pistons vs. high compression pistons.


to the original poster. if you already have the z6head and y8 im do the swap. you won't really care too much after you boost it but if you already have the parts go ahead. z6 head is good for timing especially boosted.

before you start buying parts read up on
www.homemadeturbo.com and
www.turbod16.com

see what other setups ppl have done. there are about 1000000000 home made turbo setups out there, many are very similar. follow along those paths and you'll be straight. im daily driving a boosted y7/y8 mini-me.

as mentioned above, tuning is key. 200whp is a GOOD safe limit on a stock D block. yes people push more. yes people throw rods through there blocks. if you want safe/reliable daily driver, keep it below 200whp. which means don't crank the boost.

if your that new to the turbo game, and don't have time/or knowledge of tuning, find a local tuner. should cost you about 300 bucks to get it both street and dyno tuned which will give you a SAFE RELIABLE car with damn good power aswell.

if you need more info/help lemme know

re-read my post...

the d15b has the same head as the z6, so putting a z6 head on a d15b will NOT change compression. same goes for putting the d15b head on a z6. they are the same head, the compression will not change

Awesome, that's what I needed to know! Thanks!

I'm assuming you mean the JDM d15b is the same as the z6. Is it the same as the USDM d15b2?

 

[Inigo Montoya]

Wow.

He's not referring to the d15b vtec (which isn't the same as a z6 head... its an ECONOMY motor and has a 3 stage v-tec)

He's talking about the d15b7, the only d15 that you can turn into a mini-me. f**king christ, you guys jump his s**t because he doesnt say b7 (He prolly forgot about the J-spec o0) but if you put 2+2 together, he is talking about the b7 (10.6:1 compression)

And compression matters f**king BIG TIME. LMFAO, CC has a ton of misinformants on it. Anything over 10:1 C/R you -should- (Not SUGGEST, SHOULD) be running premium 92+.

Back to the OG poster... d15b7-z6 mini-me's DO NOT boost well at all. They have WAY too high compression (unless you want to run under 5 pounds) and the weak part is NOT the block, its the pencil thin rods. The JDM d15b on the other hand, uses the same rods as the z6, so it should be able to handle 230whp on a good tune.

Sup.
