I am in the process of bringing to market some new Opel items for performance and racing use.

Items currently in development:

-turbo exhaust manifold for CIH engines with T25 flange
-Opel GT headpipes for use with 2.4 CIH exhaust manifolds, in 2.25" and 2.5" diameters
-Opel GT headpipes for stock and 1.9 Sprint exhaust manifolds in 2" diameter
-steel deep sump oil pans for original 4-speed CIH transmissions
-Opel GT Delrin AF front suspension bushing kits
-Opel Manta Delrin AF front suspension bushing kits
-baffled CIH steel high capacity oil pans (core required)
-dry sump CIH oil pans (core required)
-fabricated rear suspension trailing arms with heim joints (GT and Manta)
-fabricated adjustable length panhard bars (GT and Manta)
-watts link kit for GT and Manta (core required)
-Manta aluminum torque tube mounts
-"limited prep" big valve 1.9 heads (core required)
-roots type supercharger kit for Manta

Other items that may be reintroduced are the Manta front suspension gusset kits, and the header flanges.

I also have the stainless steel Opel GT battery trays in stock.

Viny has the right idea. You can put flat tops and a decent head together, but the cam choice, induction system, exhaust system and ignition can give you a huge range of power potential. Say 90 HP up to 150 HP.

Pictures show that you ordered a box (handful) of flanges.
Possible to do the same for the formed pan?
Can't tell by your wooden block if you are hand forming the sheet metal pan or if you used a press.
I ordered the pan rail, the side of the pan, and the bottom of the pan. All made from flat sheet.

I have to form the sides of the pan, and form the radiused pan bottom. I am using a hammer form to do that work.

A pressed lower pan would be nice, but the cost of a die set to form the lower pan would be more than all the pans are worth together. So hand formed is the alternative.

I am truly missing something. Why haven't more people treated themselves to more of what Rally Bob is offering, at true bargain prices too.
On my Ascona I have the ported intake, articulating rear trailing arms, headwork, ignition upgrades,ported carb[not offered],bilsteins, and a bunch of other things that LeGere Motorsports have helped me with. All of these things,plus having a 15,000 body, make my Opel a ton of fun to drive and it is quick.
Go on and treat your self to some up grades!

1] I am trying my best to go to Octopelfest
2] Help me Mr Wrench...why do you think ported carbs are not offered? My answer would be that a) it really is not cost effective,there is so much time to do it 98% of Opelers wouldn't buy them. b) Bob is not doing much porting due to physical restrictions.
3] I have been doing the Opel research and development with Bob for over 25 years where I would finance and Bob would develop way for Opels to be better. Things are not sitting on the shelves....You must order them!

Almost have my patterns and procedure down. The first production pan is done except for the drain and temp sender (and the optional cooler fittings). I'll be putting the first production part on one of my cars.

Took the weekend off from my shop and all car related activities. But today I finished up my own personal pan. Technically the first 'production' pan I guess. All that remains is to have it powdercoated.

Note this pan has (optional) cooler fittings fitted. They're -6AN fittings, one in the pan itself on the suction side, while the return line is integrated into a modified oil fill plug.

I was recently contracted to build a watts link system for an Opel GT racecar. The differential mods I've done many times before but in this instance I'm building the bracketry to the chassis as well. I figured I'd spend the extra time making templates and jigs this time around to expedite building future systems. And I'm having vendors cut out various components to size based on my designs, which leaves me with the job of just putting it together.

No firm pricing yet, but it's a taste of things to come!

Shame the rear diff. covers are soooo different from the 50 series cars. :bs2: Going to do any brackets for the 50 series stuff? :)

It's definitely doable. In fact I'm going to build one for someone else soon. Maybe even one for me.

Hey Bob-
Do you have an 'LM' logo to put on your parts, yet? I think it would be a nice touch given the quality of your work.

I had some decals made about 15 years ago. That was when I was doing primarily rollcages, headers, and head porting for cars other than Opels. Still have some, but the adhesive is not so hot after all this time!

Okay, almost done with the patterns for the GT watts link body bracket. Not an easy task, given the curvature of the floor pan.

I started off with .040" aluminum for the templates, but the final product will be .100" thick steel. A bit tough to cut and form!

Well the "guts" of the system are the same, meaning the differential cover stuff. The only difference between the GT and Manta systems are the length of the lateral tubes and the chassis bracket. The GT chassis bracket templates and the prototype bracket are both nearly done.

I'm building two systems for my own race car (Manta). Both diff covers are complete, so when I have a little spare time I will template the chassis bracket for that car too. Gonna probably stick a watts link on my red wagon "just because".

Hello Bob,

I'm from Portugal. I have a GT anda a Manta, beside a Kadett C City and Kadett C GTE (replica in construction).

I could be interested in some of the marvelous parts you are building, namely tha Watts linkage or the adjustable panhard bars.

Could you please let me know if you could send them to Portugal, and prices.

Thanks

As each item becomes available I will be posting prices.

I see no reason why I can't ship to Europe. I'm just not sure if it is cost-effective for you. Of course most Opel tuner parts are more available there compared to here.

My prototype GT chassis mount is all done. Just need to confirm fitment to two other GT floor pans for peace of mind, then I've one more template to make before shipping this unit out to a customer.

After that, the templates will get shipped to a shop that will replicate the parts I prototyped on a water jet cutter. So the next parts I make will have appreciably less labor invested.

The prototype kit is on it's way out. I think I have my procedures and hours figured out. I am shipping my remaining templates out for pricing of water-jet cut components. It will greatly simplify my work. I'll only need to form and weld the parts.

Once I have that pricing I can figure the costs for a full kit, or for partial components only.

Now that the GT watts linkage prototype is done and templates are made, I was able to get back to work on the 4-speed transmission pans.

I hope to have the first batch of pans welded up this week. The one holdup was the procedure for bending the sides of the pan. By hand it was slow and tedious and inconsistent.

So today I made a die set to make at least part of the procedure easier to do. :yup:

The first full production pan is done. Now to make a pile of them before dropping them off for powdercoating.

LeGere head combination...

So this 1.9 head you are talking about re-working for folks...
1) how would this work on your "2.0 with 1.5 head recipe"?
2) I have a local performance guy I use for automotive machine work, but I haven't asked if he knows anything about porting Opel heads. How would I go about getting an optimized porting job on one of your heads?

On a side note...I can't begin to tell you how much I appreciate all of the helpful information you have shared here! I originally bought my 74 SportWagon with the intention of converting it to an EV, but driving her on a regular basis makes me want to just get more power out of it and enjoy the hell out of the ICE! :) I guess that means the EV project will eventually be done to the 75 SW I bought as a parts car. :yup:

First questions you have to ask yourself (1) has my local guy ever disected an Opel head to see where the meat is and (2) has he ever flowed the ports on an Opel head and (3) does he have 25 plus years determining what works and what is just making it "pretty". After you answer those questions then I'm sure you will come to find out that RallyBob is your guy when it comes to doing development work and knowing what will make the most bang for your buck. In other words you are not only getting the job done, but your getting the best guy to do it.
