Nice! The 2" exhaust headpipe is something I've been looking for. Will it also mate up with headers you used to sell at C&R, or are they different?

When do you expect to have them available for 1.9?

 

Bob's headpipes are a bolt on for the Opel cast iron exhaust manifolds. The ones for the 1.9 manifolds will fit either the original manifold or the 'sprint' manifold. He takes a factory headpipe and cleans up (ports) the part that mates to the manifold. Re-welds and grinds it for improved flow. He then cuts the factory headpipe where they converge into one pipe, replacing the original pipe with one of a larger diameter. The 2" pipe matches the original headpipe in configuration with a few exceptions, diameter and the pipe stays true to size (2") the entire length. Mass produced factory bent exhaust pipes tend to become wrinkled or slightly reduced in size from the bending process reducing flow. Some of the factory Opel headpipes also have one pipe overlapping the other where they join into one creating yet another restriction. If this is the case with the headpipe Bob is 'reworking', he removes the overlapping section and re-welds it.

The other headpipes he's mentioned (2.25" & 2.5") fit the larger FI exhaust manifolds. The headpipe flanges are larger accommodating even larger exhaust pipes for even greater flow.

HTH,

Harold

P.S. Get you one! They're purty! :yup:

 

Dan, the only person I will do a full race head for anymore is me. That whole car accident/carpal tunnel/neck and back injury thing doesn't give me the luxury of doing any to sell. I'm just too slow-moving to be cost effective these days and it plain hurts too much to do that kind of work.

However I figured I can do a "limited prep" big valve head. You would still get all the goodies...5/16" stemmed custom made stainless valves, hardened exhaust seats, bronze guides, viton seals, hi-po 1.25" OD springs, titanium retainers, CNC cut valve job, new cam bearings, all appropriate deburring done, oil passage plugs tapped for pipe plugs, etc.

What you won't get is a full on porting job. Like I said I'm too slow to be profitable and it hurts me too much to do it. But I can blend the bowls and rework the guides to get a nice solid increase of airflow. I've gotten my prototype to flow almost as good on the intake side as a 2.2 head but with smaller ports and smaller valves. It will easily outflow a 2.2 on the exhaust side. That all translates into more torque down low and better throttle response compared to any of the bigger 'high port' heads. And it will flat out outperform a 2.0 or 2.4 head by a comfortable margin.

 

I am ordering a 2.4 headpipe still. I will need pretty soon. Just consider it a purchase.

 

I now have all the materials to build yours and Gordon's. I need to build the jig now. I'm hoping I can have both done in the next two weeks.

 

To anyone who still has old rusty battery trays. I can attest to Bob's high quality stainless steel unit. My old tray was still ok, but I really didn't want to deal with it in 5 years in a completly reassemble car. So while access on the rotisserie made it super easy I swamped it for Bob's. Man does it look good! I only painted my welds (I used steel mig wire) because I can't bring myself to paint over such a beautiful peice!

 

Got one of the components delivered today for my deep sump 4-speed transmission pans. Should have both of the other items to finish a run of the pans later this week. By my calculations oil capacity should increase to 2 quarts. There will also be a magnetic drain plug as standard, and the option of a female 1/8" NPT fitting for use of an aftermarket temp sender.

 

Bob, any idea on what you will be asking for one of these? I love the drain plug and temp sender idea. Wy the heck don't car manufactures put drain plugs in all transmission pans? :banghead:

 

I'm surprised that there has been little interest in the Delrin bushings. They improve the handling on all Opels and handling is the most important part of any car.
Watts link...very nice!

 

Delrin seems a little non-compliant for a street car. But I'm on board for a few other items, including the watts linkage.

 

The finished 4-speed oil pans will look something like this, 1.5" deeper than standard.

 

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

In all the going and coming with the Atlas Manta my gusset kit seems to have taken a powder.. If I sent you the control arms would you install them for me..?

 

In all the going and coming with the Atlas GT my gusset kit seems to have taken a powder.. If I sent you the control arms would you install them for me..?

So you're saying you don't have the gusset kit?

I can weld a kit in for you, but at the moment I don't have any for sale. It's a future plan to have more made. I just need to some of these other products out there first.

 

What about the watt linkage?
I've got a rear cover and a straight panhard core(GT).

 

I won't need the panhard core, just the diff cover. The kit will include the center link, lateral links with heim joints, hardware, and the weld-on upper chassis link.

 

I have many of the parts that are offered by Bob LeGere on my 1971 2dr ascona. I can say that each and every part, from my cylinder head to suspension components, has made my Opel amazing. Anyone that wants to make their car better should be thrilled to have these parts available.

 

I have the rear trailing arms with heim joints on my Ascona and it is a big improvement in ride comfort. All of these parts will make your car much better!

 

Bob would this head on a stock 1.9 need a bigger carb? weber 38 v 32/ 36? what cam do i use to take advantage of the larger valves? header? thx

 

You don't *have* to change anything else. But if you want to compliment the added cylinder head flow then more induction and exhaust flow would make a huge difference.

So a good idea to compliment an improved cylinder head would be:

-ported intake manifold
-38 DGAS Weber
-electronic ignition
-Sprint exhaust manifold or OGTS header
-2" custom exhaust system
-performance camshaft

Cam choice depends on your desired HP, desired powerband, and your ability to tune the carb and distributor for the cam. You could literally choose any one of a hundred different cam profiles for that.

 

If you can get an answer at that old phone number, suuuuuure....:lmao:

But I'll have to call the Buick dealer first to check inventory.

 

I just called and left a message with my order....... Where's the e-mail address on that cataloge and no mention of a web site???????????????

 

This week I finally received the components for the 4-speed oil pans. I spent part of yesterday and likely more today making the tooling to form the various components into their final shapes. Hopefully this week I wil begin welding pans together 100%.

 

I wan to get one of the trans pans..

SIMPLY TO MOUNT THAT Piece of Opel art ON MY GARAGE WALL

BTW What sorts of things are you doing for the Opel rear end.. I will buy every piece you do (Arms, rear pumpkin, what have you) as Atlas will still be using that piece of the original Opel mechanics.

 

BTW What sorts of things are you doing for the Opel rear end.. I will buy every piece you do (Arms, rear pumpkin, what have you) as Atlas will still be using that piece of the original Opel mechanics.

Currently I offer the heim jointed DOM-tube trailing arms, an adjustable panhard bar, a watts linkage, and solid aluminum torque tube crossmember mounts.

Other things I have built in the past and which could be offered again are reinforced and notched (for exhaust clearance) torque tube crossmbers, reinforced/sleeved torque tube shafts for high HP cars, modified end links on Manta ADDCO rear sway bars to make them bolt-on like OEM, even offset t/t crossmembers to compensate for lowered ride height, and adjustable torque tube bumpstops.

I really don't want to get into the spring and shock aspect of the Manta. But I can still make recommendations.

 

Only one more piece of tooling needed to start the 4-speed oil pan production. Getting closer!

 

Have pictures and prices on those.. I would like a set for Atlas.

 

Which ones Charles? Not every item is needed for every situation, and some are a matter of choice (watts link versus panhard bar), and can't be used together.

 

Well 175HP Manta, weight ratio balance should be 50/50 as I will add about 50 lbs to the center of the car as the motor is about the same as the 1.9L but the transmission is a 4 speed auto and about 50 lbs heavier.

I plan on lowering a 1", it will mainly be a show car.. but may take it out to run around a few cones in a parking lot once and a while.. it will definitely be driven on the interstate in the 70+ MPH range..

So you tell me what you would recommend.

 

I would like to buy the trans pan. Are you going to list the parts for sale on the Ad board ?
Pete

 

Probably not Pete.

The Ad board doesn't work for me, it deletes my decriptions.

So, since I have multiples of items to sell, I will list them in the vendors forum like I'm doing now. As each new item becomes available, I will start a new thread in the vendors forum pertaining to that item. Like I did with the battery trays.

Bob

 

May I ask the benefits of the deeper trans pan? (Other then the obvious gains in fluid capasity.) Is this more for racing application or does it have some street credibility?

 

The way that RB builds the deep sump is two fold.
One is a reinforcement of the transmission case ie girdle.
The other is of course better cooling due to the increased capacity.
Now you could go hog wild and and add a pump along with a trans fluid cooler..

 

You know, with all that great stuff to make and sell, you might just need to advertise in The Blitz. Advertising rates are currently at their lowest levels ever, $0.

 

Very good idea. The advertising rates are even better than RB's rates.

 

Like others have said with Flat top pistons you would probably get 100hp and maybe more. Bob has often preatched that the secret to power lays in the head and all other systems that work with it. Althouth you must understand that a Rally Bob head has alot of potential for a potent little package. And with the right set up i.e big carb, intake, exhaust, timing all working in balance, I'm sure 140 hp could be reached. Making your 2100lbs car much faster!
I hope I answered to your satifaction and ofcource Bob's.:veryhappy
