Just an FYI, something I had toyed with 18 years ago…

 

I didn't think to move the injectors down and under like that, that would definetly save me some troubles with fitment. thanks for the idea
Was there any unexpected issues with this set up??

Hopefully tomorrow I can get my cad program transferred over from the deceased laptop to my new one, then I can start the modeling process. The tech department at Alibre is closed for the holidays. I could just use the desktop computer, but no TV in that room... lots of 3d printers though.. 😆 lol.

I'm on vacation after this week, hopefully I can get the spare motor out of the other opel and get it up on a stand. It's supposed to be "rebuilt" but im thinking it just got a fresh coat of paint and some gaskets.
It's a 1970 with a 19 A cylinder head, the other 72 motor has a X19A head. What's the difference in heads if any??

 

I had mentioned in another thread about buying a set of headers off ebay and modifying them to build the header out of. Maybe modifying wasn't the right term to use as I would be chopping them up just to get the bends from.. They're cheap, and pretty sure I can get what I need from them. Have a look...

But I'm open to suggestions also..

 

I will definitely be following this thread! What kind of turbo are you using?

 

It's a T3/T4 hybrid. Runs a T3 hot side and T4 compressor housing. Might be a tad big for a stock 1.9 but should be ok with a mild cam. Probably better suited for a 2.2L

 

Curious where the exhaust will discharge from the turbo. Not much room back there in the engine bay. At least not for a 2.5-3” downpipe.

 

That's the one spot where there is plenty of room.
But I will have to wrap the downpipe to keep the heat down.
Got my cad program swapped to a new lap top this morning so I'm going to start some modeling today and might run a test print of the flange over night if the a hole dog let's me in the printer room. He was abused, has issues, and bites so hard it'll send you to the E.R. (see avatar) but I can play fetch and tug with him all day, just can't touch him. Hoping one day he will chill out and not be such a d!@$.
Also sat the 6.0 into my other project car this morning to check fitment. Going to be close around the steering box and I'll have to notch the k member a little bit but looks like it should fit fine...

 

Well while my geriatric pit crew is out enjoying themselves at a car show I decided it was time to bring the opel inside and get it up on the lift.
Sounds like an easy task, but had to move 5 cars and a tractor, and lawn mower to do it, charge batteries, air up tires and push, pull, drag away for 5 friggn hours!! I think I have just enough energy to lift a couple of beers, and maybe sweep the shop floor.
I was hoping to get the exhaust out of the 72 and spare motor out of the 70 today but im out of steam, atleast it finally made it into the shop and I can finally start putting it together...

 

The 4 bolts that attach the trans to the bell housing, which one gets the " short bolt" ???

 

The one you can't fit the long bolt into dummy...

 

I found some pics of a turbo set up done by a guy in Europe. It seems that he made his own manifold for individual throttle bodies also:

These last 3 pics appear to be a CIH engine with a crossflow head:

Wish I could get my hands on one of them.

Moving the radiator over to the driver's side produced more room to plumb, but the GT may not have that kind of flexibility.

There's just so little room. I still feel the best spot is moving the exhaust up and over the intake. I made cardboard templates of the space I have available for the intake. The tightest area is the back of the head by the passenger foot well and gives me a 6.5" square, plus a little spot for the injectors and fuel rail.
Didn't work on the opel much yesterday. Waiting on a new gasket for between the trans and bell housing plus I got distracted by my other project car I've had to fabricate inner and outer rockers for.. no joy there.

New lap top and operating system, upgraded cad program to the latest version.... GRRRR!!! have to relearn stuff again, I'm too old for this crap!!
Well anyways, I got tired of welding in rocker panels and decided to take a break and do some cad modeling for the intake.... keep in mind this is the first rendition and it's modeled so I can
stick the flange side to the bed and print it without supports. When completed, and not just doing a test print the runners will not be looping around that far...
I also want to blend the transition from round tube to square port better...and this latest and greatest cad program update doest seem so great.. could be me though...Anyway, here's a pic to give you general idea..

 

Got my order from OGTS today, all the suspension bushings, rubbers and lower ball joints. But the transmission gasket I was waiting for didn't survive the trip. Oh well I'm sure they'll have another one here in the next day or so.
So back to playing with the intake design a little.
Added the injector bungs and a flange where the plenum will bolt on. Waiting on a set of the ls3 injectors so I can figure out the fuel rail mounting.
I would like to cast it integral with the upper runners and just have the fuel rail bolted to it to simplify things.

 

better picture....

 

better picture.... View attachment 444750

Nice. Kinda looks familiar.

 

Did a second rendition today, only slightly different than the previous one... Having issues when exporting as an stl file for 3d printing. Ony happens after the flange where it bolts to the plenum is added to the model. Weird.. Don't remember having this issue with the CAD old version...

 

I feel like im being watched lol

 

Doing some test fitting. It's going to be close on the fuel rail. I won't have the injectors until next week so going to be at a bit of a standstill until then.
Printing the actual part now with the plenum flange on it. And if I get a chance later today I'll start modeling the plenum..
Anyways, pictures for your enjoyment.

 

Stuck a piece of 2.5" exhaust pipe back in there.
Close, but should be ok..

 

I think it'll be good. Without the trans in the car and just a jack supporting the engine it sits tilted to the passenger side. So once that's back in there it should have even more room.. But if it ever broke a motor mount..... Fuel line routing will also be critical.

 

The ls3 injectors showed up today.
. They're so cute and give me alot more room..
Still waiting on the stupid transmission gasket
Hopefully I'll be able to start the pattern making soon. Just want to get the trans back in and double check everything first...

 

A turboed Ascona B with a 1mm overbored 2 liter engine that makes 356hp and 449Nm and runs 13,5 in the quartermile.

I don't know any specs other than that it has a shortened six cylinder manifold.

Something for those who worry about fuel consumption. A Rekord C Caravan with a 82hp and 168Nm Isuzu-made 17DT diesel engine from a Vectra A or B. Fit like a glove to the original column shifted four speed with an 18S bellhousing.
50MPG shouldn't be hard to achieve in a GT.

Very impressive numbers, would be very curious as to what all was done. The ET is off for those hp numbers by atleast 1 second. Could be traction or gearing or a soft driver.. lol

Haven't done much here, just modeling port locations...

 

Most probably traction problems. Or less than perfect launching techniques(the owner told me that he was building an other Ascona B for drifting).

 

Drifting?? Isn't that what happens between "watch this" and " oh **** !" ?
Never got into the drifting thing...

 

Well... wiring clips for the injectors showed up today. Things are almost as big as the injectors themselves!!!

I've also been reading up on the microsquirt ecu. A couple of take aways, it can run staged injection, can provide data logging and digital dash through what they call shadow dash, and doesn't like a 60/2 trigger wheel at high rpm... but doesn't say what high rpm is.. pretty subjective on who you ask...
The staged injection is of real interest to me. Having such a low power engine to start with. Then using boost to triple horsepower switching injector sizes, and even fuels under high boost conditions is pretty alluring... I'll be keeping this in mind for sure!!
Didn't do much today, hot as hades outside. But started cutting patch panels from the 72 donor car.
I've been reluctant to cut on the 1970 parts car. I might be able to save it. Someone needs to come slap some sense into me !!!
Well, tomorrow is another cooler day

 

Still just putzing along. Still no replacement transmission gasket, they said sent me another one, but it never arrived. So I just ordered another one with a few other parts. Also pulled the trigger on the microsquirt ecu. Looking forward to playing with it.
Right now im trying to sort out the header. probably easier to just make a jig and weld it up than it is to cad model it, but why do things the easy way when you can torment yourself cad modeling weld el's with index marks on them to glue up to a 3d printed flange? I did find inexpensive weld el's at aceraceparts.com but the piece of stainless for the flange is going to be pricey, so Ill have to wait a couple of weeks before ordering all that stuff. In the mean time ill just be playing with the cad model. Also need to get out into the other shop and change the breakout boards on my mills so they're ready when I am.
This is going to be one tight package!! no wonder why I see so many people start a turbo build, and not finish..

Make sure you divide exhaust ports 2 & 3. Those ports flow more than 1 & 2, and by not having a divider they tend to run 200-300° hotter EGT’s.

Less chance of cracking or warping the head this way.

 

Looking good...

 

Very nice

Ok, rest of the parts came in so I can finally start putting things together and get it fired up and running with the webber. Looking forward to taking a test drive
Also got out and finished pulling the exhaust and drive shaft out from under the one parts car. I'll be picking rust out of x places all night long now...
. While I was out there I went ahead and pulled the spare motor from the other parts car. Definetly not rebuilt, but might have had the head freshened up. Hard to say. Going to put it on a stand and tear into it soon.
Hopefully I can get a few things done this weekend.

 

I got the microsquirt ecu last week and just ordered most of the sensors and trigger wheel. The 1970 engine is up on a stand and I'll be starting to wire things up and checking that I can see their values, and thar my laptop is communicating ok.
I'm going to use the efi intake I got from Charles to do a naturally aspirated fire up first just to get a better feel of things before adding boost control to the equation.. baby steps...
