Equal length runners I'm assuming? I was visualizing this exact location for a turbo on mine the other day.

What kind of power are you expecting?

Well i could go to $300 if you want it, if you have the room for it this is the best hands down method to strap a turbo to your six.

Well not exactly equal length runners, they might be close, its hard to mount the turbo in that spot and have equal length. Hopefully i will have hp in the low 400 range but that may be a long shot. I guess we will see.

CryO2 intercooler sprayer

well,

Hers another update i just purchased the D.E.I Cryogenic Intercooler sprayer system today. Im not sure how well it works but i figure its worth a shot. It come with a couple of methods to spray, wither push a button or use the wide open throttle switch.

That's a whole lot of spray. The 3-4 seconds should make a nice little ice shield on the IC, if you did that and WOT you would probably make 2 runs on a bottle!

Birds of as Feather...

I am a fan and a friend of Mike (MrHotRod6) down in Florida and of Larry of Twisted6 Racing as well. Just working between those two would give most anyone a "one up" on the Chevy Inline 6 World. Larry has some tested knowledge on porting these Chevy sixes that no one else can match, well short of Sissels and Santucci.

Reading Leo's book is a must. Repeat...a must. I have two copies.

Dont stop on this build, see it through for all of us.

I am gathering the parts to build a second 250 for my 65 Hardtop anticipating a Turbo application. So I appreciate you sharing the research here. I have read about more than 15 different Turbo Six Build Ups and a handful for for First gen Nova's which are challenge for room in some respect.

I am sure that Once its all together your car will be a very special car indeed.

Keep the Faith Brother!:D
