Twin setup with a tubular k member?
Call it thinking out loud if you will, but has anyone given much thought about the advantages and disadvantages to running a tubular k member and mounting the turbo's lower?
Is it even possible?
The reason i say this is because my goal with the car is to keep the stock functionality -
however, i want to dabble in the turbo world - and low mounting the turbo's would seem to make more sense...
Any comments suggestions on who may have already done something like this?

4thGens mount their twins low like that. I dont see why you coudlnt fab up a kit to do it like that with a tubular k member at all.
The thought has corssed my mind when I was gona do twins with a Lt1 motor and my tubular k member.
check out this site Im sure you will find all the pic's you need.

thanks - cool stuff over there... was not aware they had a large gm spot like they did... not much on 3rdgens, BUT, the space between the motors and the frames can't be any different right?
hell even turbolocities LT1 turbo headers hay work?

If your not in a hurry, id wait till the Sphon crossmember is done to check out. See if its any better then the others. Personally I have a PRO FAB one. Same as a PA RACING. 90% of them are all gona be the same. Its just a matter of who has beter craftmanship and welding skills.

Got a set of twin 60-1's with a pro fab tubular k-member in the 83z I built for my partner. Made a huge difference when it came time to route the exhaust. It also helped that we switched to rack and pinion at the same time

well what im thinking is doing more of an install along the lines of how the tt kits are done on the vette - next to the block between the framrails... the tubular k member makes for more room to run piping...

Has anyone here read or seen this article in PHR about the rear mounted turbo? I'm interested in this., www.ststurbo.com . I saw an article were they mounted it on an LS1 camaro.

thanks will do... i'm gonna go out on a leg here, but don't the lt1 and the gen 1 heads have the same exhaust port config? ie could i buy a set of those manifolds/headers and they fit...
i'm not looking forward to the immense amount of time its going to take to make a set...
out of curiosity - is that a twin or a single kit? can't tell with the pic being low res, but it doesnt look like the headers have the flnages on themfor a turbo...

thanks for the info on the lt1 flanges... thought so, just didnt find anything that said they were or werent...
and yeah - i am aware of having to use a pump... besides the cost, i don't really see the disadvantage of it, just another thing on the list to buy.
been investigating, anybody have a suggestion on the brand and one to use? all i have run across is ones that i dont think will hold up to the temp...

Some better views of how the turbos are mounted and some pictures of the downpipe routing. Does it have brackets that support the turbos or are the header tubes alone supporting them?

There are a few tight spots but for the most part it has alot of room, which is hard to do especially on these cars...with all that piping

I was a little lacking in the picture taking dept. when I did this one as I only had two weeks to get it done, (long story...). I keep meaning to put in a bracket to brace them off the motor but I haven't had the time to yet. They haven't cracked or unusually eaten gaskets but I most likely will still fab something up before we ship them off for coating.

No, that was taken outside my shop in worcester MA. We were at NED a LOT last year with the camaro, only it was in naturally aspirated form then. The turbo's were this years project

Folks, how much do those k-members cost and can you bolt a rack to them?

Where can I look up pricing and such for the k-member and the rack ?
