I have decided to turbocharge my V6! I will be using a turbo from a chrysler laser (eagle talon). I was wondering, if I run 5-6 psi of boost, do I need do change any internals? I know I need an fuel pressure regulator, but what company makes a good one thats not too expensive? Instead of installing an intercooler, wich I don't really need but would help, I read about something called a "Water cooled throttle body spacer". I've read that a lot of people custom make them...so I'm probably going to try Anyway, any good advice?

I'm assuming your name is Brian(form sig)

First off, all your questions are answered from previous threads. You should do a search or spend a lot of time here in this forum.

But for a heads up, running 5-6 psi will not require you to have new internals. With that said, lets put it in perspective here. People who first start to boost will not start imediatly at 5-6psi. They start low to experience. So do that first before you do anything, is experience with boost.

I dont care what anyone tells you, no matter what boost level you are running at, you need an intercooler. People who said they didn't need one, found out that they just blew the block, bent a rod, etc etc...

There are millions of companys out there who will make FI parts for you to suit your needs. Expensive? Yes they are! When you go FI- dont do it cheap bro. You'll end up paying for it later down the line. Just remember, our cars were not ment/built for FI and with that said, everything you put on(aftermarket) must(i recommend) be a good grade.

Thanks for the info So what you're saying is that I should run at 2-3 psi? Would a boost controller do the job?

Yes thats highly recommend. You dont want to get greedy and up the boost levels if you dont know for fact how your fuel system will handle the extra boost. Test first to get a "feel" of your system. When you are confident of the performance, up the boost.

Heed my advice, it depends on your turbo selection as well. Because of the various types out there, our car will react differently to boost levels. For example, a td05 14b producing 8psi will not be the same as a garrett t3/t4 producing five.

a manual boost controller, no. a computer boost controller, yes.

Either boost controller will work.

Also, you can run boost with no intercooler, but at what psi, I'm not sure, probably very minimal. I know there is a turbo kit available for the MX-3 which requires no intercooler as it only runs at about 3psi and gives you about a 15% increase in hp. But once you start to up the boost, you are going to require more fuel(run a piggy back, or stand alone), an intercooler etc....

Yes, that is a goddamn neverending cycle. Jump on it and be sure you'll be owned by boost. You'll want more and more and that's where it's starting to get costy. Once you have engine rebuilt with new pistons and rods to handle the boost, then you up the boost again and end up having a mess in ya drivetrain... I wish I'd spent my money on Audi RS4 or something nasty.

I'm tryin to design a turbo system right now. I think I'm gonna use a t3/t4 hybrid, they spool up quick and hold til redline, or so everyone says. What psi can I run on this turbo without turning my engine into radioactive mush? Intercooled of course, don't wanna be cheap when it comes to my car. Also, how much is a computerized boost controller, and what does it do, where does it mount. Is it kinda like a cd player and mounts in like that? Please dont flame, I'm still in the research phase.

with the stock wastegate on his setup, he cannot lower it to 3psi with a manual boost controller. a manual boost controller raises boost but cannot lower boost lower than it's stock setting. lets look at the laser turbo that he is going to use, i believe that its set up for 7-8psi STOCK. You cannot lower the boost level with the manual boost controller.

Though, let me admit, i'm quite hazy on auto computerized(boost input via lcd inside car), i do believe that the auto ones do allow you to rig it up (minus or plus more hardware needed to have it operatable) to raise boost and lower it as well.

To answer your question yahama(to my best knowledge), i alsmot never flame anyone( theres not enough nice folks on here as it is ). the automated boost controller goes around 2-5 hundred dollars for one and can be mounted in your stock cd player slot(s). Be it that it may, as i've said before and you do admit, DONT go cheap when you go FI Run it properly with a nice core cooler and many other parts that you will need.

I remember i've read a post somewhere on probetalk that a guy on there ran his car with stock internals up to 12psi. Notice he had a whole bunch of money invested in his engine bay to handle that much boost i.e wheather it be heads, IM ported, IM spacers, fuel pump and yada yada.

Like i said previoulsy, experience slowly. Mici is correct as i said before as well, boost is addictive, you'll love the extrac kick in the pants when u turn up the psi so be weary of what you are getting into.

after a brief brief stint on a stock internal WG on a DSM turbo, i highly reccomend dishign out the money well spent on an external, good quality one. zero boost creep.. hold rock solid at what you want it set at, and coupled with a good boost controller will not see you suddenly spiking into the 10 range under load. you tune the turbo, dont let it tune u

but yah listen to john (and mici, and 992 etc) they wont steer you wrong.

also what john said.. dont go cheap on the components. you can experiemtn and save some cash on the R&D end by welding your own pipes, if skilled enough... but dont buy a 25$ a/f meter.. it prolly wont be accurate don't get the 15$ 200,000 miles FMU from "some guy..." and dont skimp on the wastegate, turbo itself, etc etc etc.. it will just cost u more later when you have to rebuild things, tear the system down because somethign broke, etc. (good deals do come up tho, im just speaking generalities) and always overbuild your fuel system.. you will never hear a boosthead complaining that they should have went with a smaller fuel pump, or should have left out the fpr or fmu form their design, etc.
