turbo

[MATT2007]

I was tosing around the Idea of puting a turbo! on my car thear are lots of turbos around hear from cummins desiel pickups could I run one on my car If so Could some one show me a digram on how to plumb it I know I need new exhust manafolds what else would I need

jesus christ noob.

I agree, comming from a newb (to the site not cars,lol) you have no idea what you are getting in to. Do some reading and all of your questions will be answered.

[z34_nut]

theres alot of info just by reading.. theres no direct answers... every-one usually goes thier own route.

Thoes desiel trubos are designed to spool up with a lot of exhaust pressure like what a desiel puts out. A 2.8L is too small it will not put out enough exhaust flow to spool up the trubo and if it does then it will be near the red line. which is useless.

unless your going for a land speed record!! lol

lol dude i'm still kindof a noob to. I'd suggest you read http://auto.howstuffworks.com/turbo.htm ... http://www.turbo-kits.com/how_turbos_work.html ... and this http://www.turbotechnics.com/docs/turbo/turbowork.htm this will give you a basic understand of how it works. Basically it turns a pollutant into energy haha. Oh and btw if you were thinking this would be a cheap job its not. Expect 2-3k for a safe turbo setup. Also you have to build up the cars engine a hell of alot. Then suspension for the speed... exhaust. Just alot of stuff. Any more questions just ask.

give me 3 grand and ill turbo your car for you... but you still have to buy the parts...lol

You need to do a lot more research.

There are plenty of guys using diesel turbos og gas engines.

Here's a tip for you, I usually don't give out free info like this to someone who blatently states wrong info, but I'm feeling generous today.

A diesel turns at about half the RPM that a gas engine does. Most diesels redlijne, REDLINE at or before 4000 RPM, most larger diesels redline by 3000 RPM, some of the "hotter" diesels are about 3500 RPM. So what does this mean? That means that a diesel engine at twice the displacment of a gas engine turning at half the RPM will put out the same amount of exhaust flow. So that makes using these "useless" diesel turbos on gas engines quite useful actually.

yeah but a diesel turbo isnt as effiecent as a gas turbine turbo.. the spacing and design of the fins on a diesel are much more spaced out because of the excessive heat and volume of gases exhausted from a diesel engine... if you dont want boost til about 4-5k rpm go for it... ill stick to have full boost at 2800 rpm... less lag FTW

Just want to add to your list of reading...

I know it's for a Honda, but the principals are the same

You would be surprised. Many diesel turbos are commonly used on gas engines with great results. Many turbos used on gas engines are also used commonly on diesel engines with great results. Exhaust gas is exhaust gas. There's not so huge of a difference that the turbos aren't interchangeable. The biggest thing you'll see is that most diesel guys tend to oversize their turbine sides while the gas guys tend to undersize them.

QFT!

Any so called difference in the turbine wheel is purely due to trims, or the differences, not because one turbo was supposedly "designed" for use with diesel or one for gas.

Just look through junkyardturbos.com, or turbogms.com for the use of diesel turbos on gas engine with EXCELLANT results. As stated "exhaust gas is exhaust gas. Really it just comes down to how much volume of that exhaust gas is being spit out by the engine, not what fuel created that waste energy.

yes, I need to do some resreach on trubos. I work a ford dealer and work on desiels all day I know desiels better than most of you. A desiel typ. had a compression ratio of 21 to 32 to 1 and a desiel engine needs about 400 psi to run where as a gas engine needs 90 psi to run gas engine has 8 to about 10 to 1 compression ratio. yes you can put a trubo on a desiel on a gas engine and it will work but it will have a bad trubo lag. bigger is not always better. Actually a desiel will redline around 6,000 rpms so raven you are wrong about that. not all trubos are alike because trubos are designed to specific engine sizes to build the correct boost and get to most power out of an engine. A 60 deree v6 has a typ . compression ratio of 8.5 to 9 to 1 which will turn some turbos off a desiel but of exhast flow out of a desiel is much more that a typ gas engine. And no I do not need to do any research. you guys are a bunch of asses because you will attack any one and belittle them if you think you are right.

[napatiger]

Show me a production diesel engine that redlines at 6000 rpm.

I don't know anything about turbos actually. I thought about the same idea since we have turbos for our tractors....they redline at 2250 rpm.

What was that race car ....Audi? put out a kick ass turbo diesel.
