ok I did bit searching and can find any info on it. Prolly because never been done exactly like this or at least talk about alot. If some has please let me know and anyone that has any other insight thanks in advance. I So I am doing LLY swap like complete LLY top end, fuel system, ecm, ficm, wiring, etc... got all that figured out with help of Ben Tyler to figure out the wiring. So i am good and set there. just need figure out the LLY turbo.
I want to run LLY turbo with complete LB7 air intake and LB7 intercooler system with a 3.5" turbo horn with 3 inch y-bridge LB7 shorty and Lb7 stock intake manifolds. From talking with few people looking alot pictures i see there is clearance issue on the LB7 intake runners becase LLY and newer are dented in. Also I know there will be about .75 inch or so of clearance issue with 3" y-bridge and 3.5" turbo horn. I know there is easier ways like using all LLY air system stuff but I already have alot nice LB7 air system stuff like LB7 banks air intake and LB7 banks intercooler system. So I am dead set on using the LB7 system to do the swap. Yea i know i like to do things the hard way, ha.
So I took a look at alot single turbo setups on lb7 like s475 and wonder how they can run like 4 inch or bigger air intake and clear 3 inch y bridge. Then looked some stock Lb7 and LLY truck turbo's setups was like oh duh the stock turbo sit alot lower down in the valley of the block. So im think to solve all my clearance issues and still run lb7 air system stuff to raise the turbo up inch or 2. Has anyone every done this stock turbo or seen this done? thinking of just using like 1-2 inch thick steel plate to make spacer to go between where the turbo mounts to the block. Then Ill have to lengthen the oil lines and up-pipes. Oil return looks pretty simple to lengthen and prolly just run aftermarket steel braided oil feed. The up-pipes have those huge bellows. I was thinking of heating those up with torch and lengthen them like inch or 2. Would that be bad idea and shud just cut em and put piece in to lengthen them or should be ok stretching the bellows a bit?
any help or ideas would be greatly appreciated.
