Re: Syclone 934 Restoration

A metal version of the Vortec covers (taller of course) wold be pretty sweet too.

So all this time and money and hard work and the stock brakes huh? :lol:

Who needs brakes, they just slow you down :rotf:
Yea I'll have to address those later, didn't think I was going to go this far. Hindsight I would have splayed the main caps also, but oh well, it is what it is.

Re: Syclone 934 Restoration

Everything is picture perfect and looks great. What are your plans to keep the plug wires from melting by the manifolds?

Re: Syclone 934 Restoration

Super nice!!!! You making any more???

Thanks Z
No plans of yet, I think these would be more money than anyone would want to spend for valve covers.There's about $175 in aluminum before we even start making chips.

Wires are temporary, just a set we had laying around the shop.They should have straight boots coming from the plugs. The stock heat shields are installed, painted VHT header black.

Re: Syclone 934 Restoration

This project is some of the best work I've seen anywhere. Very nice. :tup:The motor mounts are a real standout.

I'm curious why you welded the push-rod plates? With the shields in place angled plug boots should be fine except for 1 & 6. (Mine seem to do well anyway.) I'll look forward to see how you protect the wires themselves for 2 & 4 as they come past the DP. I just snaked them through a plug boot to protect them. I suspect yours will be a bit fancier. :lol:

All in all gorgeous work! Props to you and your shop. I'd bet there's some seriously nice work going out the door.

They are two piece adjustable and once you get them set you need to tack weld them to keep them from moving, if not they can twist while tightening.

I wouldn't think so because of the size of the notch but better safe then sorry. Thanks.

Re: Syclone 934 Restoration

I really like the wrinkle paint. How much time do you have drawing all this out on the computer? Did you recover all the aluminum scraps from the valve covers?

There was about 1 - 1 1/2 days of design, there were a few changes, this included reverse engineering the original covers. Then programming, machining and finish work took another 3-4 days. We didn't keep close tabs on the time. The chips just go in the metal scrap bin, they become contaminated with coolant and steel and we only get scrap rate.

Re: Syclone 934 Restoration

I've had some time to get more machining done. Made a T3 input adapter with a port for a PW46 external waste gate (made from Inconel 600) and a 3" down pipe flange (made from 420SS).

Input Flange







Down Pipe Flange





I haven't finished machining the Waste Gate Port, need to determine where I want the Waste Gate. Would be nice if I could weld the V-band straight to the adapter and mount it there or I may have to route it elsewhere with SS exhaust tubing.

This would be ideal but not sure there will be room.



Also made a EGR block off plate

Re: Syclone 934 Restoration

I love your work. That looks amazing. :tup:

How much would a set of reverse engineered Vortec valve covers with a 1/2" spacer built in cost? Based on the plastic ones but a little deeper for roller rockers?

Re: Syclone 934 Restoration

As many have said, very nice work. I have been thinking of a way that I can run an external waste gate on my GT35R and stock manifolds, but I just don't see how I have enough room with the A/C, inner fenders, ATA piping, etc. I will be interested to see how your setup fits in the truck.

Thanks, I would think a single prototype set would be more than anyone would want to spend. It starts with about $175-$200 in aluminum alone. There was about 4-5 days worth of design,programming and machining. Most would go with an aluminum sheet metal set that would be a lot cheaper to manufacture. I don't see why the ones I made won't fit a Vortec heads? Stock valve covers fit Vortec heads with stock rockers, I think.

Thanks.Yes it is very tight, ideally you would want to run the waste gate off at a 45' angle with the flow, but there just isn't enough room. I left the waste gate port un-finished until I know exactly how it will be run, I will port the inside to help direct flow.
