More stuff I probably don’t need to be dealing with. Jeff, I’m going to be doing a lot of modification on my rear end and turbo kit. I’m going to tack it all in place, but get ready for some welding 😉 2000 Viper Diff, 3.08 gears. ![http://only-here.net/carpics/rx7/viper.jpg](http://only-here.net/carpics/rx7/viper.jpg) ---

looks good. something i found out when doing truck manifold setups is to put flex pipe in there. that pipe will still move a bit and may crack. ---

becareful with flexs. ive seen the inside of a flex turn inside out and clog up. thus restricting the turbo. little late for this but i think its C5 manifolds flipped foward would allow you to run your hotside downlow. nice progress! ---

I’ve actually debated on the flex pipe. Have advantages and disadvantages. I ended up going with the thicker .065 walled tube instead of the .049 to avoid cracking. Quik, I want to run the hotside up high. With the subframe there’s not much room to run the downpipe if the manifolds go low. ---

Depends on the type of flex pipe i guess, some are made different than others. get a good quality one and it should be ok. Although its best to not have one before the turbo anyway, sometimes its needed ---

With the subframe there’s not much room to run the downpipe if the manifolds go low. makes good sense then. I didnt run a flex on my crossover on silverado’s setup and didnt have any issues with cracking. i however would make a turbo support, that tubing isnt strong enough to hold the turbo alone with abuse. and idea is since your ls2 has a 90mm tb already run 4" to the tb, since you have a 4" diameter TB its best to keep same size tubing to it. it will also help in a cooler charge. i go from a 3" outlet on the IC and use a 4-3 reducer. i have never seen anything higher then 20\* above ambiet with this setup and no meth ---

Have someone put an adapter on the IC to make it 4". I dont know how good going 3 to 4 will do, that little restriction point should be eliminated if all possible.
