Just bought a 78 mm fast for a good price to replace my ls6 intake. Kinda funny guy bought it and never used it had it for 8 years and its brand new in the box so I said why not. But either way is there any other way then buying new coolant lines? Could I modify the stock lines? Also I would really like to have all 4 corners vented but just want to order what I need by tommorow. Anybody have some suggestions?

 

bump it up

 

You can flatten out the stock ones and be fine...but for 50 bucks id do it right.

 

Havent found it for 50 bucks. But know I think i mite just go expensive and get the kup vapor system.

 

$50-60, if that's an issue just hulk smash down the ones u already have...good to go.

 

haha dont know if I want to do that. BUt I do have several hammers lol.

 

well I'd like to buy your ls6 if you want to sell it. when you change it.

 

I will let you know. Mite be a week just trying to gather parts so I install this fast correctly and going to port the fast myself.

 

What I'm doing is getting 2 ls6 style front cross over's and running a line from behind the intake around the side and connecting it to the front before it goes to the radiator.

 

Dam, u been looking in my engine bay?
I got same thing but use the truck 2port crossover in rear and ls6 in front.
Connect them with brass t. Parts store rad.overflow tubing.
Problem solved.

 

Op,
Just a tip for the valley plate cover and fast intake.
I took a countersink to the plate and tapped the m8 threads in block for 5\16-24.
I got the countersink allen bolts for about .20¢ each.
Not all the bolts need it. Just the ones interfering with intake body.
I spent less than 5$. And didnt pay for the fast button heads.
Done it for few other folks who bought intakes without bolts.
Can also use 5/16-24 button heads, if not countersunk bolts
Thr m8x1.25 pitch is very close to the 5/16-24.

 

Good to know. Havent decided to go with the kurt urban or rig up two crossovers.

 

If you want to do it on the cheap get another front crossover and reverse it on the rear heads then run a line up to the front T into the front line plumb it to your water pump or radiator

 

for 50-60$ id really do it right from the beginning...specially with a fast. since you saved some from the price it self..piece of mind is priceless.

 

Rig the 2 crossovers and use the cash saved for something else. I reccomend the truck crossover in the rear because the outlet tube points up instead of laying flat like ls6. Use ls6 in front of engine. Tie it all in with 3$ brass T or Y. And 3-4$ worth of tubing and hose clamps
