Well except for intercooler mounts (I need a real intercooler core for that), and a full exhaust system, all the mechanical aspects of the GT turbo kit are prototyped. There is still the fuel rail and other EFI parts to consider, but the main bits are done.

Man dats alotta pipes!

Hmmmm, it appears that starting a large project such as a full turbo kit development would not be a wise thing mere months before I close down my shop.

Or so my GF tells me....?

So it looks like I'm going to stop where I am, at least for a couple of years.

Does this answer your question George?

I don't like smilies me

Nice work Bob, would have been interesting to see what you could have done with a TR6 head some day .....

I just finished the 2.5" turbo downpipe with O2 sensor bung. 18" from the turbo flange is the norm...overheated O2 sensors are a problem if they are in the turbo manifold or too close to the turbo outlet flange.

Nutin better than a turbo charged automatic.

Let me make this perfectly clear George. I asked you to stay out of my threads previously. Yet you persist in being the internet troll that you are, and post anyway.

You fail to ask relevant questions in all your threads.

You fail to post in the correct forums, instead posting nearly everything in 'general discussions'.

You post new threads with exactly the same questions you've asked previously in other threads you've started.

You may not have 'broken' any forum rules, but you haven't followed any since day one either.

You are, in short, a waste of my time and I'm sure of many others here, comic relief notwithstanding....

Please refrain from commenting further on any of my projects. I have not yet made a turbo kit for GT's. I may never produce or sell a single kit, I haven't decided yet.

I have, however, decided I won't sell YOU anything, regardless of how much money you bring to the table. It's not worth the irritation.

There is no one more helpful to people, more willing to answer questions with serious, helpful and direct answers than RallyBob. There is no one more patient. And when he lost his patience with you, georgeopel, a few weeks ago, while out of character for RBob, he was justified in doing so and totally appropriate. Now take the hint.

Well, I went and pulled the trigger on the last item to fabricate. Ordered an intercooler core today. American-made 3" thick core, 7.5" tall x 12" long. I'll weld on some end tanks and mounting brackets and we'll have all the parts on hand to turbo a GT. Hmmmmm....

Well, I don't think you will have any issues finding buyers if you do decide to produce these kits. Makes me say Hmmmmm too :lmao:

Not true. I doubt I'd sell 5 of them. It always costs more that you think. And when you factor converting a non-EFI car to EFI, plus aftermarket ECU, fuel pump and injectors...well, not many folks will bite.

The funny thing is, if you buy a late model performance car that already has EFI, it often costs $6000-$7000 to add a turbo kit and gain maybe 150 hp on a 400 hp engine.

It would only cost maybe 2/3rd's of that amount to convert the Opel to EFI and add a turbo, which can add up to 170 hp over the 70 hp baseline the car came with originally. So proportionately, it would still cost a bunch less to turbo and EFI the Opel compared to buying a mass-produced turbo kit for a late model car.

The real costs arise when you factor in a modified suspension, bigger brakes, bigger wheels and tires, stronger transmission, stronger clutch, and either an LSD for the original rear axle or an axle swap. If you ran the full 240 hp potential through a stock Opel driveline you'd break everything, and it would probably put you into a ditch even if it didn't. The car would have roughly 340% more power than stock. It would be a terror to drive.

That's true, but you may be surprised though. I bet after a few people successfully converted there GT over and detailed a nice build thread, others would follow. To gain a 100 hp from a turbo would be sweet, but I guess it all boils down to how deep they want to dig in their pockets. There would definitely be a "cool" factor to having a turbo charged GT.

If you take a 1.9 bump the compression ratio to 10.5 , a bit bigger light valves, street porting, 38 weber with ported intake, a bit of a cam, bigger exhaust, ignition, lighter clutch and some fine tuning you can get very respectable results. To do this nicely it is still going to cost 5 to 6k. Take to rest of the money that you are allocating to this project and put it into brakes and suspension upgrades to make the car balanced...too much motor and not upgrading the rest of the car is a bad idea.
If some one puts down another 7k for a turbo kit they are going to have to match that number doing upgrades.
A true 125whp in a GT is a good amount of power and with bigger brakes and suspension bits, you can have a lot of fun.
When you do things right it gets expensive very quickly. Rally Bob knows that there are 5, if he is lucky, that would kick down the cash to do it right.

Yes it is good quality porn.

Yesterday the intercooler core came in. She's a beauty. American-made, bar and plate design (better heat sink than tube and fin design), and the dimensions are exactly as advertised. Not cheap, but quality seldom is.

You'd need an intercooler at least 50% bigger if it were a cheap China-made tube and fin intercooler in order to provide the same cooling. Trouble is, the pressure drop would be unacceptable, and there's no room in the front of a GT for that big of an intercooler without cutting stuff up.

Gonna be nice.....

 

[RallyBob]

So tonight I fabricated the intercooler end tanks, and welded them to the core I just got. They're made from .060" thick 5052 aluminum sheet, except the tubes themselves which are .060" thick 6061.
