Builds 1FZ-FE TRD S/C Rebuild (10 Viewers)

I completely missed that on you original post lol

It really isn't necessary to drop compression ratios if you are using the stock TRD SC'r and the stock sized pulley. Just make sure you're feeding it premium 93 octane fuel, that your injectors have been cleaned and that you have a good fuel pump. You're just not running enough boost to need lower compression, if you were going to try and push 10-12psi with that SC (don't think it's even possible) than yes you would need to lower compression since it would be very hot IAT's and detonation could be a real problem. But instead of custom Pistons you're better off from both a reliability and power stand point to get an intercooler or water/meth injection. An A/A intercooler is pretty dead nuts reliable.

Where I live 91 octane is the best we have here at 4900 ft.

Stopped by the machine shop today and they said they should be able to get to the block to surface it in the next few days. Looking forward to it and hope that works out. The motor has been there since the last days of June last year, but he's done me real well on builds in the past and is my best option here.

 

[thetoyotaman]

So, I went over to the machine shop and discovered they finally moved my block off the floor to the boring machine. It will have to head over to the surfacing machine first, but it was great to see it moving.

For those of you who you have successfully and reliably have painted your blocks, any suggestions on treating the rust or not? Thanks!

What's rust?

 

[thetoyotaman]

He he!

 

[thetoyotaman]

Block was surfaced. They removed 6 thou.

What options are there for core plugs?

 

[sbman]

My machine shop sourced all of the core plugs, I asked for U.S. made parts, there was one they couldn't get that I got from Toyota, a big metric one. There were a couple of small ones that were NOT available from Toyota.

I used a rust conversion primer on it, just scraped off any loose rust like it said on the can. I then sprayed it with black tractor paint with hardener. Has held up fine so far (12K miles).

What's the pros/cons of brass versus stainless plugs?

 

[thetoyotaman]

When I was at the machine shop tonight, his main source for engine building parts did not offer any freeze plugs for this motor. If I go with brass core plugs, where can I find them? Not having any success online yet.

 

[thetoyotaman]

It looks like we're going to go with brass plugs as possible. The machine shop can order by size.

Another question, do you guys feel that a pyrometer and trans temp gauge are necessary or just wise? Thanks again for all the help!

 

[thetoyotaman]

Spoke with the machine shop today. He bored the block and it only required 20 thou which I was thankful for. Pistons are ordered.

 

[Rivman1243]

I would get a wide band O2 sensor, boost/vac gauge and a trans temp gauge

 

[thetoyotaman]

Yes, bought a PLX setup and planning on that.

 

[Rivman1243]

Yes, bought a PLX setup and planning on that.

Which one did you go with

 

[thetoyotaman]

So far I have the vac/boost, AFR, and pyrometer and plan on adding the trans to it.

 

[sbman]

Nice to have the block in process! The shop I used used brass plugs, but there were a couple of large ones that were not available and I had to order from Toyota. 32mm I think? The large ones on the end of the block.

Pics of the block and offending cylinders.

Pistons and rings are here!!! Machine shop very pleased. I am super stoked to get! It feels like we are starting to get somewhere.
