It still has less than 30k on it since i built it. The cometic head gaskets have less than one oil change. It's still pretty fresh. Id say about two years of being build but it's put up every winter and or was broke down for other reason for a while.

Good to know. Still excited!

Did you sleeve your block Shane or just put forged slugs in?

shane881510 · May 3, 2016

Forged Pistons and rods and new bearings. Cometic head gaskets. Arp head studs. everything but sleeves. I'm not going push for max power just want more
Tq and maybe a little bit more hp..

You could also try a set of cams, down the road. Pick up a nice bit of torque with those as well. Put them in the wish list basket for the future.

I swear you must make commission on those cam sets. :rofl:

They'd definitely be more prevalent and easier to get, if I did!

shane881510 · May 4, 2016

I'm having hard enough time to get a better blower, cams are way out of my price range.

shane881510 · May 16, 2016

So I got the big boy blower, the -92. Should be here by Friday. So I have a c38-81 for sale now. Just the head unit only. Let's start at 1500$ And work our way down.

Hell yeah!!! Woot!!!!

shane881510 · May 18, 2016

Looks like i got my blower in. Had to rotate the housing. But all i need now is a bottle of oil and filter.
It's awesome looking and rotrex uses billet compresseor wheels. It looks rele big I didn't have a caliber gauge to measure the wheel.

Torspd · May 18, 2016

Damn it! So to be time to get it back on the dyno!!!!!!

hiflyer · May 19, 2016

What's the difference between the -91 and -92?

shane881510 · May 19, 2016

The -92 inlet is 3.5" the -91 is 3"

May be interested in that blower you have for sale

shane881510 · May 21, 2016

I'm gonna buy a new elbow coupler 3.5" to 3". Just message me about the blower kwigs. I can make u a good deal on it.

I'm just gonna do some digging around and see if it would a good fit for my ls swap. I'll keep you posted. I really liked it on my 1gr

They work. There are LS kits with the -81 available. Some folks have used twin -71s. Some use a small nitrous shot to help out low end for 1/4 mile ETs.

Don't expect huge boost numbers, especially intercooled. But they will feed a stock internals LS motor well enough.
