Anyone have pictures of a single turbo setup on their 3rd gen. Looking to get ideas on plumbing and clearance etc. If any one has a single turbo setup, what turbo trim did you use and how hard was it to fabricate the exhaust for it? Looking to run between 5-7 psi with a 9:1 compression, could I do more? All forged internals on the engine.

 

Well, you can start with this thread:

Plus, you can visit my webpage (in my sig) and look around.

 

very nice car you have there Guido, I'm figuring I could make about 100 more HP to a 300 HP engine with a single turbo setup, T66 trim would work well for a healthy 350. Do you have a boost controller for your car?

 

Yes I do. Its a norgren air control valve. Looks like a regulator for an air compressor or portable plasma torch. I bought it from a local industrial supplier.

 

Here is one.

 

Another

 

Yet another

This is the cleanest one I've seen. His headers resemble block huggers.

 

Another, not as nice as the others

 

another of the motor out of the burgandy car

 

The other side. BTW this car is reportedly very fast.

The other clean way I've seen the single thing done is to use a stock type oil pan and a block hugger on the drivers side... the exhaust exits the block hugger and wraps under the motor in the stock location between the pan and crossmember then goes up instead of back. The drivers side would use something that resembles an manifold flipped upside down. The two pipes would come together into a common collector and place the turbo in about the same location this one is in.

 

The engine above is a 305. In that burgandy Camaro it ran high 9s at around 140 if I recall, supposedly very tame and street driven. Don't know anything about its present level. There was a video of it circulating around here a couple years ago.

 

that looks simpler to fabricate than a twin turbo setup, how are it's street manners? As much as I'd like to run 9s, I'm looking more for a mid 11 second car. Would a single T4 be too small for a 350? How is the clearance in the engine bay for that engine?

 

ya, its a big bore 305 though.

 

would a twin turbo setup be more practical for a daily driver? I found a nice pair of SBC headers that used to be on an L98 Corvette with a T4 twin turbo setup

 

you have any pics of them?
are they for sale?
are they yours?

 

they are for sale. They look more or less like modified stock headers with T4 flange and wastegate flanges welded on.

 

ya ok.....i thought they were actually headers

i'd bolt them up to the motor and see if they will work

 

There is a picture of them on an L98 Corvette, I am assuming they would fit.
I also found this turbo kit and a set of grape ape headers on ebay are they any good?

Headers^

 

Block huggers will not clear the crossmember on a 3rd gen...

 

LOL that second system looks mighty familiar dont it?

 

Yep, What I should have said here was a stock style DS header thanks.

 

DS header? I probably sound like an idiot, but what does DS stand for?

 

DS= driver side

block huggers wont clear a STOCK crossmember but will an aftermarket one

no, the grape ape headers wont work

 

how come?

 

what if you took a driver side shorty like this one on the right

and put on the passenger side, brought the pipe down and under the oil pan into an upside down, modified block hugger? The block hugger would be the turbo manifold and would be on the driver side. Would that work too?

 

Measure how much room you've got from the valve cover to the brakes, strut towers... and then take a good look at a set of the grape ape headers and it will be clear, it's not even close. They were designed for 2nd gen engine bays

zerotosixtyV8- well, the driver's side is designed to fit in an f-body, so that's fine. The passenger side... well, that's up to what you do there. I would say that most block huggers will put the collector up to high to fit a turbo large enough to be used as a single. You'll also run into a hassle with down pipe routing if you intend to run a decent size since the recesses to run the exhaust under the engine and chassis are reversed from what would work well for this application

The fact is that most of this trying to hack together existing stuff to work well, well, will end up hacked together and being a PITA and take more time then just building the right thing to start with.

 

What about modifying the stock manifolds into log plenums for a twin turbo setup? I'm exploring options, going for the most cost effective. Almost all the turbo manifolds I see online for sale look like modified stock ones, either off the L98 camaro or corvette.

 

what block hugger header is that in the 3rd last pic ???

 

It doesn't really matter, he made it fit using a custom K-member...

 

They are not purchased block hugger headers. They are totally custom built one off headers. I know the owner and also the shop that built them. Ive spoke with both. They are made from 321 stainless.

They were built and do fit a factory cross member. He has since switched to a tubular cross member.

 

Those wont work either. I purchased a set of those thinking that they would work before Ibought mine. They are hooker 1 5/8" super comps arent they? They will NOT fit the cross member.

I like the thought process though.

 

yeah, those are super comps lol. I am trying to visualize it in my head. How about modified L98 Corvette manifolds? Would those work? Flip em upside down and have two T4s up top? or have one up and another down and run a crossover pipe to the otherside and have a T66 there.

LOL

 

JoBy said if you cut off the AIR tubes and flip em upside down it should work. Worth a shot, L98 manifolds can be found for only a few dollars.

 

This is modified L98 headers with the flange cut off.

 

Guido... are you laughing at me?

JoBy, thanks for posting pics of my stuff so I didn't have to. Hell, I've probably posted those a dozen times and people still ask eht same question. This place really should have a 'search' to prevent that...

Yes, they will fit like that, yes, you will have to do some cutting and modifying to clear the brakes and hood (really, the best way would be to hack the collectors completely off and make your own), no, I don't like how they fit so the car won't be leaving my garage like that or with the 2 T3's that I've got sitting around (mostly because I wanted to do something different, too many people have done stuff with them and I was really looking for something a little different then that to start with anyway).

 

No I laughed because I found it ironic we were discussing the vette manifolds in that other thread and he asked about it in this one.

*shrug*

No offense meant.

 

this thing is huge Dan, got anymore info about it?

 

i got my blockhuggers to fit on my 3rd-gen i welded 1'' plate on the motor mount brackets.

 

... now that's what I call bringing a thread back from the dead!

 

I guess you have strong motor mount brackets now. What does the plate have to do with the headers?

 

I'm not for sure what he means, but it might have to do with the fact that block huggers don't fit thirdgens because they hit or exit right on top of the motor mounts.

 

Does anybody know whos burgandy car that is??? I really like that and would like to know some specs on it.

 

yea, its more practical.. lol.
