Builds My turbo build...FINALLY! (1 Viewer)

[landtank]

This build really isn't a good one for referencing cost. I've used and sent this guy a bunch of work over the years and he's helping me out on cost where he can.

leaving out the engine work I'm shooting for around 3500.00. But since I've bought some of the components over three years ago I'm not sure how accurate that would be but I'll make my best guess.

Fuel economy, that's a joke right? My final boost target is 18psi which will be around 500hp at the crank. Fuel economy isn't much of a consideration on modifications such as this.

Hi Rick,

Looked but can see - what AR is the impeller?

Sorry if I've asked you this before

Sorry I forgot about you, .70ar.

Landtank & 96r50- Thanks for the info last month. Eagerly following this thread. Good luck with the project.

Sorry I forgot about you, .70ar.

Cheers

So you're running a GT35 .70 cold side, .86 hot side.

What wastegate will you be using?

Also, at 18psi, what are you doing to the bottom end - crank, conrods etc. And I'm sure I read about you lowering the compression ratio somewhere.

Keep up the good work!

hot side is .82. All I'm doing to the bottom end is tightening everything up. My guy says that it should take 18psi all day, we'll see.

You'll be fine at 18psi. Just make sure you have a fresh headgasket in there and your AFR's & timing are good.

Im crossing my fingers for you. I hope your engine builder is that good. I afraid of pushing stuff that hard. If anyone can do it, you will be the one. "You are my boy blue".

excellent.

I got me engine back from the shop over the weekend but had other things to do so here is the update.

The work done is as follows

Pistons:
planed .100"
machined ring grooves
Balanced

Block:
dipped
honed
replaced oil pump bushing

Connecting rods:
Resized
balanced

Crank shaft:
dipped
balanced
micro polished

Head:
dipped
valve job
flow benched

Intake:
dipped
bead blasted passage ways

replaced rings, rod bearings and crank bearings.

All in all the only wear item was the oil pump bushing. The machinist called me up and was pleased to tell me that the crank mic'd out better than perfect, whatever that means. In the end he was able to order bearings from a manufacturer that he feels is the best out there. I don't have the name right now but can post it up later.

And before you flame me for not using Toyota, this guy was a big Chevy I6 racer and he was having so much fun with what he saw as the perfect I6 but never had. So I'm going with his recommendations because he is as excited about this project as I am and just wanted to do it this way for him.

So the pics are of the top of one of the planed pistons, the oil pump bearing, the intake passage and a few others.

WOW thats alot of machine shop work. All done at the same shop? What was that bill?

 

[fzjconvert]

SHHHWING!

Yes it was all done at a single shop. Like I said he was a race engine builder. To bring the crank into what he feels is a proper balance within .25 grams he spins it at 16,000 rpms.

He's kind of an eccentric guy. If you drive by his place you would never know what's inside this old garage.

The funniest thing I saw in his place was the heating thermostat. It was mounted to a stick of wood that was wire tied to the end of a no longer used garage door track and has been there forever. LOL

 

[96r50]

Very nice Rick! It sounds like you have found a machinist with a great background and experience.

For those of us who hopefully in the future will be adding this manifold to an engine in situ, is there a line somewhere between how much of this work is imperative and how much is optional? I realize that every situation is different, but what are your thoughts be on the necessary maintenance or PM that should be done before adding a turbo? Nothing, HG, full-blown overhaul etc?

 

[landtank]

Guys are running 10psi on these engines with no issues. So I would say that as long as the HG is of the current design and the engine has been taken care of you are probably OK.

I have run into a few engines that have rod knock so a good idea would be to pull the oil pans and plasti-gauge the rod bearings or better just replace them.

This might sound like alot of work but along with the bearings this gives you an opportunity to install the oil return line. Most companies will have you drill and tap a hole for that. I'll be welding on an -10 an bung.

I'm going over board just because. I got a great deal on the work and knowing how I am likely to start pushing past the 10psi mark I wanted to go that extra mile to know first hand the condition of the engine I'm working with.

So as a general rule, the amount of boost you want to run will affect the amount of work you should do to the engine?

I would do the same thing if I was in your shoes! I can't wait to see the rest of this thread develop!

Hey Rick, I tune in here and there to this thread....so sorry if you've answered this, but how long are you estimating this engine is from being installed, pressure fed, and burning gas? I'm very curious to see how it all turns out, I know you have GREAT effort, time and $$$ into that exhaust manifold!

 

[landtank]

Realistically it a few months away at least. I've got a few custom parts still to design and that will take getting the engine into the truck. The truck is in the back yard and we're just entering spring now. Before I can boot the wife out of the garage for the summer I have to make sure there is no more snow.

I know I'm moving incredibly slow but I enjoy putting the effort into making a piece as close to a factory design that I can.

Those pistons look like they were "planed" with an angle grinder.

Nice work though. I like seeing people build homemade turbo systems.

 

[landtank]

I don't know if planed is the correct term but they look like hell in the pics.
