Hard part to get your hands on is the lower manifold. Blower companies do not sell those separately, otherwise there would be gt500 blowers on a lot of LSx engines

Re: LS1 Swap Crew: This is my Supercharged LS1 swap thread

So my GMHTP article never came out, since they closed the magazine.

However, editor Rick Seitz started his own website www.gm-efi.com to carry on with what is the new to me GMHTP.

They just launched my article today

Tom was there and showed me the car which was on the lift and being worked on. What I saw was a piece of art! I somehow have more ground clearance with my lowered 3rdgen with longtubes and 4" exhaust than a stock 3rdgen has. I was impressed!

My spohn crossmember was removed from the car, and Tom had to custom make a new crossmember or else the exhaust never would have fit. Its hard to explain how he made the crossmember. Hell, it was hard to even SEE the crossmember...it was tucked right up in the trans tunnel.

The headers had v band clamps installed on them, and the lowest part of the collector barely hangs below the frame of the car...this really surprised me.

Off the headers he used a pair of 3"-3.5" oval adapters, into a 3.5" oval Y and mated it to the over the axle pipe which was left round.

Wouldn't you know I forgot my damn camera! So I went back to the first shop, got my camera and some parts, then went back to Toms. Here are the pics I took, in no particular order












As you can see there are a ton of measurements, tiny pieces, tack welds etc he has a ton of time into this exhaust, and a huge chunk into the crossmember....it all fits TIGHT.

Its amazing quality and probably worth every penny of what he's charging, but I never would have authorized him to do it. Even PCM of NC told him he dropped the ball and should have called me,

One of the main reasons I'm not still livid is Tom seems pretty interested in trading my T56 swap I have for sale towards a big chunk of this bill. If he will do that, I will be a happy customer.

Holy crap, he actually MADE that oval pipe. He cut pipe in half, then added metal to it. No wonder it took so damn long. Looks bad *** though.

Re: LS1 Swap Crew: This is my Supercharged LS1 swap thread

I'll get some updated pics soon!

Haven't been to the track yet! I had Hawks install an S60 over the winter. I'm still breaking it in. I don't drive the car very much. It seems I'm always hauling something whether its equipment, or trash, for my business. I tend to drive my truck just about every day, which means not many axle break in miles lol

Re: LS1 Swap Crew: This is my Supercharged LS1 swap thread

it started breaking (assuming) from too much power. I had it repaired and sold it to help fund my S60.

I still have some axles and bearings for a dana if someone is in need

Really? Lol I saw a few posts recommending them, though they could've been beefier versions not necessarily stock.

In your opinion, would it fit a stock hook or would you need the cowl for the extra room? 84/TA here with the Factory cowl induction hook (functional power bulge). I've got my motor mostly together and this thread caught my eye. lol...

Awesome build! I was the one on the FB page that was asking is this would fit under the hood of an 89 Iroc. I will take another route since I love the factory hood sooooooo much!
