Carb Conversion "Kits" ETA March-April 2016

[content22207_2]

I’ve been out of the carb conversion practice for a couple of years, but am curently building up a small inventory of “kits” (no step-by-step illustrated instructions, but everything necessary to do a complete conversion in one box), estimated to be ready in about a month.

I will have both dual plane and single plane intake manifolds available (dual planes are basically “street” manifolds and single planes are basically “race” manifolds – very different operational characteristics and very different power bands).

Dual plane intake manifolds are fabricated from scratch:

Single plane intake manifolds are adapted Peugeot 604:

In addition to the intake manifold, I will provide:
- All hardware
- Square profile O rings
- Rebuilt carburetor (pre-tuned and test driven)
- Air filter housing with custom lid
- Throttle cable bracket
- Throttle cable ball end (manual transmission) or throttle cable clevises/shoulder bolts (automatic transmission)
- Full throttle kickdown microswitch bracket (automatic transmission)
- Injector port plugs
- PCV valve
- All hoses and clamps
- Generic fuel filter and bracket
- Fuel pump carrier (rides in stock tank boot)
- Fuel tank baffle (“tuna fish” baffle)
- Charcoal canister blockoff plate (optional)

My own car has been carbureted since 2004. I’ve been making conversions for other owners since 2008. There are currently 21 iterations of my conversions in service – it’s a well vetted design. Every conversion gets test driven on my own car before signing off. Installation takes a couple of hours. Carb conversions are totally reversible (to date no one I have assisted has either gone back to K-Jet or to EFI). Both Del Silviera and John Marconi sold their carbureted DeLoreans without any price penalty.

Final costs are still being tallied. I expect complete “kits” to cost less than $1,500.

I will post progress updates as they become available.

My own car (intake manifold is Volvo A Series, on which my dual plane manifolds are patterned):

Interesting jig set up for welding.....

Interesting jig set up for welding.....

Welder uses a K-Jet manifold to set up the jig. Yields manifolds that bolt right up:

I am using a new welder for these latest manifolds (I don't have equipment to weld aluminum -- I machine the pieces, he puts them together). He is doing a very careful job. Owners should be pleased.

So the guy who got banned from here, went to another redneck forum, turned into a pariah there, and now is back here? Good grief.

Dear mods, please do your proper duty and get this pimple banned again.

Was just a matter of time.

Best of luck Mr. Robertson...

Should probably post an explanatory picture: from a distance Peugeot 604 manifolds look like dual planes, but they are in fact single plane -- there is a large common plenum under the two venturi bores:

Del Silviera's manifold had those two openings routed out into one big hole. A Renault Alpine group in the UK is doing the same thing (and welding Holley footprint adapters). I suspect Peugeot originally used the two venturi bores to support a divider the baseplate gasket.

I am one who favors second chances. This forum is an incredible go-to place for Delorean technical knowledge, and I think Bill's experience is an asset. Let's not throw any stones yet, shall we?

Welcome back Bill.

Welcome back Bill!

Looks like you've got a nice collection of PRV intake manifolds there! I sold my spare and am now down to one. I'm keeping that for my next car...I think.

Glad to see that you're set up to sell an inexpensive alternative to K-Jet. I know I spent about $1500 on K-Jet on my first D just to get the motor running. If I had known about carbs back then I'd have gone that route.

Bill reached out and wanted to post his carb progress in a thread under this sub-forum. I said sure, just stick to the car stuff. Regardless of what stuff happened in the past, if this information and kit helps some DeLorean owners out there, than I'd rather have it be a productive thread.

Did you forget to list a "low pressure" fuel pump?

P.S. Welcome back Bill!
