Interesting Turbo Question.
I'm creating a new topic because I didn't really want to hijack the banks turbo topic.
I was staring up at my ceiling last night trying to sleep and I had an interesting thought run through my head. If the accessories are in the way of the turbo, and it'a a big pain to move the accessories, what about moving that one turbo??
Some of you will remember that I tried doing a beltless boost project(try the search engine) last winter. It had the twin turbos mounted low on the car. I got the drivers side one on there, but couldn't figure out how to get the passenger side one on.
Could it be possible to put one mounted high with the banks headers and one mounted low with the header I've already got? The only thing that would come to mind would be the possible differences in back pressure because of the different headers, but I don't think the differences would be that great to matter much at all.
Do you guys think it could work??

I can tell you that on my Twin Turbo Corvette, the frame has a section removed so the pass. side fits - Did you know over 1000 addl. / different parts are used in the factory TT :eek: :flag

Re: Interesting Turbo Question. (mn_vette)
Yes you should be able to move that other turbo to another location but you will have to adjust the boost on that specific one! But i am thinking of running a big turbo in the place of my blower and use my exhisting piping and intercooler i have from my ATI!
It will be a lot of fun!

Re: Interesting Turbo Question. (krivera)
The only thing I can see you using from your ati kit is the intake side of the turbo, obviously. If you plan on having a single turbo, where are you going to have a crossover tube for the exhaust? There really isn't any space for one. That is why everyone seems to go with a twin turbo set up on C4's. I would love to have a single turbo set up on my C4, you could run a huge turbo with the exhaust coming from a V8, you could make an insane amount of power and a lot of top end.

There's plenty of room for a cross over tube on my LT1 infront of the oil pan.

Re: Interesting Turbo Question. (Red91Vette)
Then wouldnt your down pipe be pretty big? Im thinking like a 4.5inch pipe splitting into two 3inch pipes going to the back. Plus you might want to get an oil cooler in there somehow to cool the heat from the crossover pipe. :yesnod: Good luck :seeya

Re: Interesting Turbo Question. (Light84vette)
WHo says you need exhaust out the back? (except the government) All those turbo race cars are not that loud in person, and most have very short pipes exiting the turbo and dumping in the area of the front wheel. That would surely save some space

Re: Interesting Turbo Question. (SBNova)
Ok this is what i have found....
Pull the blower from the drivers side and create my own bracket to run the altinator backwards the same way it is set up on the ati but i wont have to mount a blower so cut that piece off.
Then create a custom drives side header like so!--->
Then run the pipe over from the passanger side like so--->
Then run the turbo into my intercooler using my ATI setup like so..
Also after talking to my turbo import friends they said to make sure all my piping is jetcoated and then fab up my exhaust 3 inch back to my chrome tips!
I am sure it will be pretty easy having most of the work already done (ATI piping) so basically build my custom header on the drivers side...run passanger side exhaust over to custom header...then mount and bold up everything and run the exhaust and tune!
But my import friends did say to make a heat shield or a hood scoop to let either cool air in to hit the turbo or heat shield to block hood from turbo so i dont burn a hole in the hood!
They said it would be really easy but controling a V8 into a single turbo can blow the motor pretty fast if not tuned right!
i think with my tax return i will fab up a kit and sell it on my website?
What do you guys think?

That is the LS1 Motorsports Fbody kit isn't it? I don't think running the piping is going to be the same or be that easy as it looks on that Fbody kit. Are you good with welding?

Re: Interesting Turbo Question. (Red91Vette)
oh hell no i dont know how to weld but i have a friend that owns a exhaust shop. But yes the engine is a LS-1 but it does not matter a 350ci is a 350ci and making a header like the one you see above will work fine. I will be using some of there ideas but not exactly what you see in the pic. i will move around the waste gate and blow off valve ofcourse and air filter so all in all i am taking the idea and making my own.

Re: Interesting Turbo Question. (krivera)
Actually its 346cid and the headers are different, the SB's we have in out C-4 and from the past all have the two middle headers close to each other, the Ls1's are all apart like a Big Block.

But same principal on the drivers side header. I am not going to replicate someone’s design like the LS-1 fabricated header I am going to Design it for a late model 1 piece rear main seal right hand dip stick 350ci.
So it is going to be a fun project and I am thinking of converting my belt system on my vette to a V-type belt and run a cog from the crank to the blower and everything else will be V-type.
What would really cool is run a shaft drive to the blower like they have for the imports!
Either way it is going to be interesting and I am sure I will hit a few snags on the way building a turbo system in place of the D-1 for those who are looking at getting a turbo on the vette.

Re: Interesting Turbo Question. (krivera)
this is very similar to the cross over style manifolds on the buick turbo, these aren't particularly efficient looking, but it will package and work really nice.
a single BB BIG turbo can spool just fine. with the sudden torq increase when boost comes on, you actually WANT just a bit of lag because the sudden power increase is much like nitrous A BIG HIT.
SGC is currently working on a TT ZR1 project, and they may also be interested in doing other c4s too. I have a 94 LT1 Auto that would be perfect.
with the great prices on c4s, you can pick up a killer LT1 auto, put a nice D44 rear in it, beef the trans, and a rebuild engine and single turbo and make some killer power for way less that new vette bucks and be more distintive to boot.
my daily driver is a 600 hp buick turbo, and it's just amazing how the "buzzn half dozen" can make some much torq.
as the import guys will attest, turbos can make some big power, the industry is just now "catching up" and getting more turbo cars built.
this setup looks REALLY nice, thanks very much for the pics.

Re: Interesting Turbo Question. (Rkreigh)
That LS1 one kit has me thinking.... There is enough room on the driverside for a turbo right? Well if I got shorty headers, on the passenger side, run them down and over to the driver side. Cut the Driver side off at each individual primary and weld it into the crossover tube? Headers are the hardest part of the installation set up in a custom turbo kit IMHO. So using modified shorty headers will take a lot of the custom work away, hopefully making it easier? Think this will work? Just an idea, I have to look at my engine bay and start taking dimensions.

On that f-body kit the crossover runs under the bellhousing? We have hardly any ground clearence as it is, I won't want the crossover to be the lowest portion of my car.

Re: Interesting Turbo Question. (scorp508)
Agreed, I have to look at my car to see exactly where a crossover tube would fit. Also have to think ground clearance wise for the downpipe. I plan on prolly switching to a manual trans though, I wonder if there is more space with that then a auto? I would assume so, especially with the downpipe, because the manual trans is smaller.
