and just 1 statement.....
2) all the guy's with a similer set up to mine please all info would be greatful!!

Re: boost and B20Vtec
 

oh one more little detail of the motor i forgot to add......

i have accell 350 cc injectors

Re: boost and B20Vtec
 

Run a fridge for a start

Re: boost and B20Vtec
 

fridge??????

fridge=INTERCOOLER!! am i correct?

Re: boost and B20Vtec
 

yep....

1) get an intercooler on that bitch
2) get a chipped ecu and run like 8-10psi :6

Re: boost and B20Vtec
 

925,743,018 psi
throw a tornado on it and youll get better fuel economy O0

Re: boost and B20Vtec
 

but aren't the sleeves too thin to run 8-10

Re: boost and B20Vtec
 

you need to do some searching there buddy

Re: boost and B20Vtec
 

350cc injectors are to small. 450s are the SMALLEST upgraded injector you should use.

the sleeves are only to thin if your tuner sucks balls. detonation kills motors, not psi.

Re: boost and B20Vtec
 

i was only planning on running 5 to 8 pounds of boost..... im not a wanting MASSIVE setup...

i have a buddy im going to have tune my car for me. he is a ASE MASTER tech he tuned his home made turbo setup with a t25 at 12 pounds of boost and the thing was a monster for a semi built d16z6

Re: boost and B20Vtec
 

Fix all the fail in your build, then think about boost; until then DON'T boost anything.

Re: boost and B20Vtec
 

lol!

Re: boost and B20Vtec
 

What crxvtec91 said is pretty much true.

Stock ignition is fine and you don't need a "boost timing master" or "boost retard switch"... your head is in the right place that you need to retard the timing under boost. However, once you chip your ecu you can control ALL of that in the tune using crome (or whatever program you choose). Research some more... if you're going through all the trouble of port work, for God sake get an intercooler.

this is LOL-erskates.

ok been hangin around here 4 too long with-out posting so its about time i post some shiznit...and i'll post some porn for all you pervz later in the general discusion sec.but anyways man i am one of the few that wanted to try out the stock b20vtec setup when i blew my gsr motor so i pulled the head off my gsr found a cheap b20z block i used arp headstuds,cometic head gasket,and golden eagle oil kit. slapped it all together put it in my car threw on a knock off greddy turbo kit took it to slowmotion motorsports had it tuned it on crome pro with 9psi put down 342hp 248tq all stock motor had it for about a year now with now problems.but everybody on this web site is very smart when it come to cars and well pretty much anything and ive seen some werid post before so thats my exprince with a b20 ;)

Re: boost and B20Vtec
 

ok this is my second day on here and everybody is already hatin on my set up,
if im not mistaken this sight is called home made turbo

so also im not trying to make any enemy's already i was just trying to get info on how much BOOST a STOCK B20VTEC can handle
all the stuff i bought was on a fully built d16z6 crx that ran bad ass

this is my home made turbo setup

Re: boost and B20Vtec
 

oh by the way...

i got a different set up today.... 2.25 inch charge piping turbonetics xs blow off valve and a front mount

Re: boost and B20Vtec
 

Hum some people are hating on you, ---- cry me a rivier. Take a look arond, I thought they where taking it easy on you. Also I pointed everything that is WRONG with the setup you listed. BTW where are you located?

Re: boost and B20Vtec
 

read the faq.
your question is so irrelevant that it has fail all over it.

Re: boost and B20Vtec
 

you can probably push 13-15psi with no tune anything after that you will have to tune though

Re: boost and B20Vtec
 

shhhhh.
:3 dont tell him any more.

Re: boost and B20Vtec
 

Just because it's homemade doesn't mean you can't do a good job of it, and research.

""FULL MSD IGNITION"

useless, you didn't need it or hacked in boost retards... Crome doesn't get any cheaper then free, all the MSD ---- is just a bandage.

Re: boost and B20Vtec
 

your tryin to get info and i tryed helpin you out by tellin you my setup on my stock b20 motor and its not really how much boost your motor can take its the horse power it can handle with me i never thought 9psi would hit 342hp.. that's really pushing a b20 to its limits just stay under 300hp and don't drive it hard all the time tryin to impress all the girls you pull up next to or mabey guys whatever floats your boat :l

Re: boost and B20Vtec
 

Good, you got an intercooler... now go re-read my post about using a chipped ECU.
