1FZ-FTE build

[Corbet]

So with the Wits’ End turbo kit nearing its ship date it’s time to start building an engine. I picked up a parts truck over the weekend from a friend who bought it for the body. He rolled his and plans to rebuild it with the donor sheet metal. I arranged to receive the engine/trans/t-case. I didn’t want my truck torn down for a couple months. So the plan is to build this engine and simply swap it into my truck. Do some break in miles and then bolt on the turbo.

 

[Corbet]

My engine builder is Bill Lee. I dropped the truck off to him yesterday and he got started today pulling the drivetrain.

About 5 hours later he had the complete drivetrain out.

 

[Corbet]

He will split the head off and see what we are dealing with later this week.

Plan is a pretty stock refresh with the addition of forged pistons and probably ARP head studs.

I need to get started researching what pistons I want.

Also plan to do low range gears while it’s all apart.

Sweet! Forged pistons, good idea. Sounds like a fun project. Subscribed

That's a nice body.

Thanks for taking us along for the journey. It sounds like it will be a fun one! Sub'd

That's a nice body.

from the firewall back its good. got whacked in the front pretty hard. Both quarters have damage. frame horn bent, etc... Or wait were you talking about Bill in the 2nd picture?

I just bought an engine off of Calvin with the intent of doing the same thing.

I am planning to build it myself over time and see how this turbo kit pans out for first buyers. Glad to see soemone local pulled the trigger!

Does the kit allow for use of both stock cats?

 

[Corbet]

Kit is in process of getting CARB certification. It will be CA compliant.

 

[Jacket]

That's awesome. Pretty exciting to think about the end result.

Wish I would've kept that.
Yes it uses stock y pipe, so it basically replaces just the manifolds.

I couldn't tell from the pictures on the website and was certainly not going to read that entire thread. Whew!

OEM cast manifolds stay. J pipe mounts to them and holds turbo. The only non-bolt in part of the install is mating the exhaust off the turbo to your remaining exhaust. If still OEM you cut right before the cats and weld on.

Oh, sorry for putting that wrong information out there

Awesome Corbet!!!! Are you going to intercool it and do Meth injection? What rings are you going to run? Stock ECU?

 

[subzali]

That's awesome. Pretty exciting to think about the end result.

He posted the following dyno results:
1. Stock 120AWHP/170 FT LBS
2. Supercharger 155 AWHP/238 FT LBS
3. Wits End 214 AWHP/277 FT LBS

So about 100 hp/100 ft-lb increase.

Turbos are fun

If you are changing the pistons, have you given any thought to boring out the cylinders? Isn't that what PowderPig does when he rebuilds the 1FZ to a larger displacement?

 

[Corbet]

1FZ rebuild party.

 

[Corbet]

I’m still deciding on internals. Piston size will be dictated by cylinder wall condition.

Joey plans to offer an intercooler (water/air). Will definitely upgrade when I can. Been thinking about Methanol injection.

Stock fuel map. 7.5psi max.

Is it ok if I just put this here? Long live the 1FZ!
