LS1 BUDGET TURBO I've been thinking about this for a year now that i have another daily driver, which is a 93 5.0 lx ha ha, the time has come to take action.
Here is my situation. I stripped out a spark plug hole in the dr side head on my 98 so I have a set of brand new 99+ heads sitting at the house. Needless to say the mistake turned out to be a gift. So this will cure the problem of weak valve springs and pushrods when I replace the heads. They will be ported but not milled so as to keep stock compression.
I have a few ideas for turbo placement and I wanted to see if anyone could improve upon or add better ideas. The first was a single turbo located where the battery is, relocate that to the trunk. Cons are that I would have to fabricate a passenger side ex manifold and run a crossover from driver side and the exhaust would be a bitch to get route back and the possibility of burning paint off the hood. Pros are that I need only one turbo and no scavenge pump.
Second idea Incon style twin setup which looks much easier. I could fabricate two down pipes from the ex manifolds to two turbo's. Cons are that I need two turbo's and a scavenge system. Incons system shows a dr side manifold that was smaller than stock so I dont know if my idea would work on the dr side due to frame clearance. Pros are easy setup easy exhaust routing cooler under hood temp.
My third idea was a single setup underneath on the passenger side with a crossover from the driver side under the bellhousing. Cons, scavenge system. Pros are that I can retain stock manifolds or get some shortys and everything would would be easier to route. I wanna be the first kid on my block to do this. It can be done most people are worried about boosting high compression engines but ati, powerdyne and vortech have been doing it for years. Give me your ideas.

Re: LS1 BUDGET TURBO personally, a homebuilt turbo setup is very difficult, and the LS1 engine bay makes it much much more difficult.
I have thought of it, look how some of the single turbo kits work, and look at the complexity of the piping. If your up to that task, by all means give it a try, it would be sweet. I plan doing more indepth research into this in about a year, but will be building all the parts myself, starting with a set of header flanges (GM PN#12480130 and then lots of mandrel bends.
What i would do in you situation, is Twin turbo the mustang, as on that car, you can flip the headers, and it will be a lot easier, use 2 turbos, from 5 speed turbo coupes, there is a lot of info on stangnet about this.

Re: LS1 BUDGET TURBO I have thought about the stang, But why spend money to put the stang where the ls1 already is. I guess i am just tired of of the crowd of ford guys with blown 4.6's and 5.4's that their powerplant is better we all know these things without boost are nothing. Let me throw a few pounds of boost down the throat of an ls1 and see what happens. But I have seen the the upside down shorty setup for the stang and it does look easy. But the car feels like it was designed for a teenaged girl its cute. Nobody taught me to hate fords, I learned. When I drive it and I catch a light with a f-body I try not to make direct eye contact like most mustang owners. And this mustang is souped, b303 cam ported and polished intake and heads aluminum roller rockers march pulleys and ram air pro flow maf 65mm tb mac headers and no cats and lt1's and ls1's run away from me stock. I bought it like this for 1250. from a guy that got tired of my almost stock Z28 smacking him around, he now has a 02 ta.

Re: LS1 BUDGET TURBO HAHAHAHA!! ROFL, HAHAHA!!
He actually said "LS1", "Budget", AND "turbo" in the same sentence! Nothing on the LS1 is "budget" oriented, let alone FI.
I looked into building a turbo kit awhile back. I actually had built the header's, and had 2 T3/T4's mounted where the battery is and where the fuse boxes used to be on the passenger side. After about 2 months of downtime, and almost enough cash to buy a single kit from a sponsor I gave up. If you get it done, you da man! Good luck! <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Re: LS1 BUDGET TURBO Neat you are right. Hell with it, I'm gonna turbo the 93 fox body. $2000 for a forged crank is more than I spent on my modded 12.9 1/4 mustang. I hope the GTO's sell well to get those aftermarket LS1 part prices down!

Re: LS1 BUDGET TURBO After working with my car for the time i have building the turbo system and a second on another car it can be done.
The trick is all about finding parts used or second owner... Now doing the turbo over by where the battery is should be no problem. Reason being is that it has been done there already. Heat is only going to be a issue around the exhaust housing on the turbo and you can keep that heat shielded Innovative turbo heat shields.
The headers are going to be the only costly thing as they should be made out of stainless so the steel doesn't flake off after multiple heat cycles.
So if you are ok with welding stainless...
and poss alum for your intercooler. Then you are set.
The mustang guys get rid of lots of turbos and the buick guys do time to time as well. Just gotta search for deals to get a nice price.
