I'm pretty amazed at all of the turbo experts chiming in with the do's and donts of turbocharging. All of these comments must come from years of research and countless hours working in your own machine shops. Most of you clowns with the exception of John of course have probably never set foot in a shop except to drop off your neighbors parts. John specifically said it was for more show than go. Nothing is perfect even from the factory. I feel so blessed to read all of these comments and be able to take all that knowledge with me to the rest bench. PFFFFFTTTTTTTT. Great work John and a great vision on this project. Keep up the great work, love your vids
Thanks for the enlightened comment. These turbos are not that much that you couldn't buy one and play around with it. The tubes are pretty large (1.4") as compared to the port (1.1"), so volume will be sufficient and it will flow pretty well. Time will tell. Just posted a vid of a new intake for the SU, so I will try pass-thru and blow-thru setups. Research & Development - that's what Costa Mesa R&D is all about!
If my client had deeper pockets, I would do that exact thing, however.... He's on a budget and I made what will get the job done for that cost. I've make 4-1 manifolds and they do tend to make better power. Take a look at the Offy's that were run at Indy for so many years, they were using log-types, as were many others. Glad you liked the video. JE...
I'll see if the owner can take some video when it installed and running. The car is not local to my shop, but I may start the engine on the test stand or maybe the dyno.
Hey. I recommend doing 4-1 exhaust manifold. the smaller pipe. of which can be easily exchanged. experiment with both types of the bench, and then select the better. PS: thanks for the great videos
There's a good book called "Maximum Boost" that might be the best book on turbos. If there's a better one, let me know. It says that the draw through set up isn't the best. I can't remember its short comings however.
Check out my Blueberry 850 Sedan, I put a VW trans in that one, but will use the VW engine because its much lighter then the 124TC, and the VW trans is 10 lbs lighter then the 850 trans.
@fiatnutz I have seen that kind of exhaust header on other fiat 903 cc motors could the manifold from a fiat uno 45 be used instead how many lb/ft of boost are you running and why not use a garret gt 12 instead
If that was the Turbo flange that you use its going to kill the exhaust flow you should made it a little smaller the the inlet on the exhaust side of the Turbo or port matched it with what looks like 1/8 over hang. On the inside of the two flanges you well have really bad Turbo lag
I have see on TH-cam and it looks like you some kind a Fiat nut…(best intension) Have you ever had a go at making a Fiat Abarth OT 1600 Replica? Nickname “the widow maker” The one with a 1,6 twin cam engine (180hp)and Porsche gearbox I can get the Fiat 850 and a 124 TC engine and properly also the Porsche gearbox, but the rearframe seems to be my problem
Im not so sure your exhaust manifold is going to be healthy for the engine. In my opinion, the number 1 and 4 runners are going to cause turbulance when their gases smash into each other. They should have be blended better with a 45 degree angle, into the turbo's collector flange. That's just my two cents, but its not a smooth and efficent manifold design. Even a 4 into 2 into 1 manfiold design would be more effective.

I subscribe, Im rebuilding my 850s - 69! Love your vids 👋

Came for the fiat but stayed for the music, what do you used, Roland juno, ensonic, korg? Let me know haha and drum machine too : )
This in the first video when after watching, i don´t want to see you soon. That exhaust manifold make me get nightmares.

Another interesting thing is as the fuel vaporizes it cools the inlet charge which is something that fuel injected systems dont do very well :-)
Looks awesome!
I was originally for a small diesel engine, size is that of a T-15.

No merge collector John? Turbo looks like a good size
please make a video of it running and driving it after

Should run about 12 psi, will run 9:1 compression. Expecting around 100 hp, could be a tad more. The original engine was 52 hp.
Not on the 850 Fiat, but there are plenty of other vehicles that use turbos.
john you smoke some killer weed the music gives you away lol

Where can I buy this turbo kit for my 1970 850 sport coupe?
This is what alien porn music sounds like.
Nice fabrication Jon. Looking forward to hearing it run...
wowzer

personally i think them runners are too long for d size of engine ...and d mainfold design gonna create some bck pressure

not the best flowin thing but some function it will have
It's for historical race and I will never get a VW engine approved ... Maybe I can get away with the gearbox, but not the engine.
Not so good exhaust manifold IMO.
