OMFG your gonna boost 20psi w/ a GT35??? that CRAZY... how are you going to keep it from lifting the head off the block? i know a guy w/ a turbo integra making about 450 at the ground that was running a T4 and lifted the head a bit and it started to let coolant in when he would boost.

Yeah I want that DOHC kit for my SD4 when I get it
I was running some parts numbers through GM Parts Direct, and ran the Part # on the Superduty Engine Build Package (PN 10031328) and it came up as they still have it! For $114.81 Did you use this in your buildup? And what else would you need to complete the build-up, beside the block, head, and intake and exhaust manifolds?
Is the head in there the same one used back in the 80's, will it bolt up to the older (or KRP's ) SD4 block? Or the holley intake?
In one part they say: "General Motors Service Parts no longer offers this super duty block, but Kansas Racing has been licensed to manufacture and sell this style four-cylinder block. Contact: Kansas Racing Products at 785-922-6644"
And the intake manifold that looks like Holley's? "10038470 Intake Manifold (4V) Your Super Duty engine will breathe deeply with this single-plane aluminum intake manifold. It mounts a single standard flange Holley four-barrel carburetor. Special runner cross-sections optimize flow to the end cylinders. Its tuned runners are engineered to work with the ports in Pontiac Super Duty cylinder heads"
It looks like they have TWO heads: 10045437 Cylinder Head 10049801 Super Duty Four High Port Special Aluminum Cylinder Head
But they don't list ANY prices?! They've got almost everything I've been looking for! I'm guessing the prices will be the only thing holding me back I wonder if you can email them about the pricing?
Same issue with the yellow and black notchback SD car that was at the 20th. I'm not sure if they still had the SD in it then though (@ the 20th). I can scan those pages too.

There was an earlier version head that required more prep work. The new (current, I guess you could say) version came out almost immediately following, in 1984. But yes, the 437 will bolt up to the block/intake/ etc. At this point, I believe KRP is focusing on making blocks compatible with the SBC heads. I would love to have a KRP block, though . Having seen one in person, I can tell you taht they are superior to even the Pontiac SD blocks. That being said, there's only one Pontiac SD block, I don't believe it went through any changes during its production.

Don'tcha like it how people compare engines like apples to oranges? Following the thread, first it was the 2.3l FORD turbo engine and now it's an INTEGRA engine. After reading the first page on the SD by John Baechtel, it seems this engine will pretty much survive anything. Granted, 20psi is excessive, but I believe it'll fare better than a run-of-the-mill 1.8l Integra POS.

Basically, all of the engine fasteners and the waterpump is included with this, except for head bolts and main bolts, if I remember right. I'll check later today, I have the darn thing in my basement. I'll scan the package list maybe.
I looked into the dual overhead cam head for my SD Indy and ran into dead ends. It was a limited production head that was designed by Cosworth. The upgrade was expensive - around $6,000 for the setup if I'm not mistaken. I spoke to a rep at Kansas Racing Products and he basically said "Good luck finding one" The other suggestion they had if you wanted to go 4 valve per cylinder on the SD was to buy one of their blocks which is machined to fit a small block Chevy head and buy a ARAO Engineering head. http://www.araoengineering.com/Chevy/chevysmb.htm That of course is out of the question for me since I have a complete 3.3 liter SD4 built to Vanderly specs.
Nice build BTW

Yeah, you're lucky to find more than a rumor of the DOHC head. As far as the ARAO head goes, you're looking at ALOT of custom work there. Did you talk to Gerry? I believe he mentioned to me in one of his e-mailings that he had found a couple of the Cosworth engines several years ago, but nothing now.
Thanks for the compliment.
Right now I'm looking at head gaskets. Obviously, 20 PSI is alot and I do not want ANY suprises with this engine. I'm not very excited about having the block O-ringed, either, but if that's what it takes....Anybody ever hear about Cometic gaskets? I went to their site but I couldn't really find any tech info about their gaskets, just the application listings.

i was looking for one of those heads.. that'd be perfect.. but still out of current pricerange.. one day i think i may do it - but not today
FastIndyFiero - I have a few spec sheets for the superduty as well as parts lists and even blueprints. If you interested in these let me know and I'll scan them.
Here are the spec sheets for my SD as asked.
3.3 Liter/ 193CID 12.8:1 compression Supposed to be a tad over 300 HP not sure about torque figures.

Emails on the way. - BOUNCED BACK you have a PM. There is only 2 pages of SD4 parts. The rest is SD6 and SD8 parts.
Njoy!

That DOHC head @ 9.5-1 and some boost might hurt something. I'm guessing 400-500 hp with a 7000+ rpm limit.
I'm planning to hit 9000 with the 2 valve head. Pics of the short block coming soon, I promise. A rear seal adapter is being made for the crank, then it goes together!
You need to fire that thing up, chester, with some video, too!
I have to get a starter for it. I have quatermaster working on it. As soon as I get the starter issue resolved, I'll get working on getting her running.
