more d15b7 turbo questions
 

*ok since the search has not been working for me for 3 days now, i am forced to start a thread*


anyways, thinkin about doin a hmt kit on my brothers 163k mile d15b7. looking to keep it reliable and safe, probably around 150whp-ish. of course, the motor is and will remain all stock. what are the weak points? rods im sure, so where do they max out around? anything else i should be concerned/informed about?

i wish the search was working bc i know all this has been covered before. and dont think im a bitchassnoob bc im not, i just dont know much about these pos b7's. O0

Re: more d15b7 turbo questions
 

rods on those things are weak as balls..... they look like they were made for a weed wacker...

but why bother asking, just boost it, B7 bottom ends are a dime a dozen and you can get them for free..hell i just gave one away...

Re: more d15b7 turbo questions
 

how much hp do these tend to take a ---- on?

*EDIT*
and the reason for not "just boosting it" is bc he is 16. he doesnt have much money. and he doesnt have another car. not to mention its 25 degrees here and i really dont feel like doing over night motor swaps in this weather;)

Re: more d15b7 turbo questions
 

no money equals home depot/junkyard ghetto turbo set ups.....

cold weather equals more time to get parts as you can afford each one....

I have seen b7's making 200whp.... and holding together.... but in my eyes they start getting sketchy after that

Re: more d15b7 turbo questions
 

well then, running 8psi on a gt17 or a 14b and wanting 150-160whp i should be ok

Re: more d15b7 turbo questions
 

14b is the perfect "starter kit" for a d15. Just limit yourself to 6 or 8 psi max, as those turbo's are capable of alot more. IMHO best bang for the buck, and cheaper than hell to build these days.

Re: more d15b7 turbo questions
 

cool, thanks. so far this looks to be the potential setup upon finding the right prices on items:

14b
1g dsm bov
1g dsm smic
hf mani
dsm 450s
fmu
custom oil lines

why buy an FMU.... when you can tune with uberdata or crome for free.... just buy a chip and get a friend to burn it for you

Re: more d15b7 turbo questions
 

i have a crome chipped p28 but idk anyone to tune it, and certainly have no clue how to do it myself

Re: more d15b7 turbo questions
 

for the sake of saving money.... run a basemap on it.... its probably just as good as a FMU

Re: more d15b7 turbo questions
 

idk how to do that either.....i guess we'll see

Re: more d15b7 turbo questions
 

anyone else have input?

Re: more d15b7 turbo questions
 

buy a basemap chip from ------------- for $18 and plug it in your ecu yourself

Re: more d15b7 turbo questions
 

read in the turbo section b7 is like a any usdm d15b block plenty of examples over there


tuning is key and there is not one # that works


simple trial and error is really the way this stuff works

Re: more d15b7 turbo questions
 

I've been running mine most of the summer on 10psi with no problems, I rape it daily, I have a long drive to school and usually go through a 5th gear ripper or two a day, that thing seriously should have died along time ago. Besides the wideband I put my whole setup together for $550 plus the wideband and chip burner. Thats including my Homemade 2.5 full exhaust. Just go for it but do your research first. Tuning is pretty simple especially for a non V-tAk. If you send me a chip i'll burn my map on it and send it back to you. I'm using 450's, and a teo4h.

i have a hf manifold shipped for 30 bucks

Re: more d15b7 turbo questions
 

thanks guys!

ifly87 - ill let you know when im ready....have you dynoed or ran it at the track?

riceburner700 - this is for my brother, so let me talk to him and see how much money hes got. you have any vouches?

Re: more d15b7 turbo questions
 

riceburner, pm me info, pics and contacts for that manifold. ill take it if you got some vouches

Re: more d15b7 turbo questions
 

No havent dyno'd it or ran it at the track, paying to dyno this setup would just be a joke, and I dont want to embarass myself at the track with it, its not bad but i'd get a lot of ---- for my gay bodykit. hopefully this spring I will have my z6 build in there, then I'll take it to the track.

Re: more d15b7 turbo questions
 

thats cool, ill let you know what exact setup i end up with and ill pry send you a chip if you can help me out with that

Re: more d15b7 turbo questions
 

i've seen a dyno of 214whp safely. i think he was running about 14-16psi. the guy has his own dyno and shop though so he knows what he is doing. some of you guys may have heard of zerodaze.

Re: more d15b7 turbo questions
 

damn, on a b7? do youknow what turbo he was using? I just got one of those freescale map sensors so I'm going to crank up the boost a lil bit. what do you mean by "safely"? I've seen most of them go right around 215-230 whp.

Re: more d15b7 turbo questions
 

good news is, we just picked up a z6 swap foro $300. boost will wait a bit, but i wont complain
