Project: Huron Speed + 1999 Z28

Progress is progress! Take what you can get!

Where will you be running the drain back to? Front cover?

[1999Black_Z28]

I decided to run the drain into the oil pan. I considered the front cover because it's easier to remove but I want as much drop in the return line as possible. Do it once, do it right

RPS is awesome to deal with, bought lots of stuff from them over the years.

To bad the Comp oil-less turbos are so expensive - screw the feed and return!

[1999Black_Z28]

Yeah, I hear you on the Comp turbo's. It would be nice to run oiless but it's hard to justify for the price. Plus I think you still need to run coolant

Coolants the easy part tee the heater hoses and done

They make oil-less turbos? Since when? I have never heard of such a beast.

Yes Comp turbo does - a few threads about them on LS1tech. They are triple BB and have billet compressors, and seem to make some serious power.

Interesting, wonder how the long the life will turn out to be.

It needs to go back to comp turbo for a service (they tear it down and put new grease in it) @ like 15-20k miles or something like that.

Yup they use an ultra high temp grease that needs to be serviced every so often. Another badass thing about them is they can be mounted vertically. ( http://media.photobucket.com/image/v...1/DSCN0198.jpg )

Mifbody thread jack already in progress. Sorry Dave!

damn if u ever need any help, id be glad to come lend a hand. work in GR 6 days a week (54th and 131)

[1999Black_Z28]

I may just need to take you up on that offer Especially when it comes time to drop the pan for the oil return

Made some progress this past weekend. I installed the 317 heads, 60# Injectors, and 2 bar MAP sensor along with some other things. Here are pictures of my progress:

Removing heads


Installing ARP Studs


Both heads installed



There has been a lot of discussion lately about the importance of the rear steam vents and coolant crossover tubes. Since I still had my LS1 crossover tube from years ago I decided that now was a good time to install it. The only downside is you need to grind down the ribs on the bottom of the LS6 intake in order for it to fit but that’s a small price to pay for potential benefit.

Intake ground


Intake installed


At this point I decided to get the car running NA with the new heads, cam, and injectors before installing the turbo. This will enable me to dial in most of the VE table in the non-boost regions and work out any bugs I might have when converting to speed density and loading the new injector data. I figure it will only take a few extra hours to re-install the airbox, radiator, stock exhaust, etc to get the car running again and it could potentially save me a lot of headaches down the road.

I also installed the first piece of my Huron Speed turbo kit…the MAF delete (although it’s only temporary)


Here’s how the engine currently sits. I had to order new pushrods because my old ones were too long. Once they arrive I will install the rockers, valve covers, coil packs, etc, etc and get the car running soon.
