Update. Update. Update.

 

Damn! Nice avatar pic!.


Updates huh..................well......................................................................................

 

it moves under its own power...

 

Well, I took some pictures of my rotating assembly, as best I could, for another member building his engine. Something to the tone of the rods interfering with the oil squirters. So I took pictures showing that my squirters are still installed. Now, there was an adjustment which had to be made to the pistons. They had to be clearanced/notched, so that the bottom of their shirt would not hit the squirters.

Which can be seen in these pictures.

 

I just paid off a second built engine. Non stroker, but sleeved. That will be here soon. Needs a little TCL, but can be back up and proper pretty quickly.

Went to Kozmic Motorsports on Monday, to have them change the injector size, on my ProEFI. Ran into a few glitches, but will be back up there soon enough to get that finished with. Was missing some files. Then I can at least run the old turbo/kit as well as finish up a get things with the exhaust routing. Keep it at low boost, so I can at least have a little cure for my addiction, while I wait to finish the built engine.

Found a new highly recommend guy to do my crank work. Need to get all of my tolerances together so that we know how much material can be removed. Then, pull the crank and give it to the master.

 

Hey man, what did you use for your gaskets? Ive been pointed towards using the Cu based high temp FIPG for all the seals (turbo and headers) vice the metal gaskets.

 

On my headers to heads, I use the OEM multi-layer steel gaskets. Between the turbo flange on the turbine housing, and the T4 flange on the up pipe, I use a copper gasket. If the flange on the up pipe has irregularities, any back pressure will blow that gasket maker out. Unless you have a large turbine housing and large A/R, to reduce back pressure. For me, the stainless T4 gaskets would always leak. My T4 flange isn't perfectly smooth. The copper gasket, fixed that leak and have never had a problem since.

I have known of techs at PowerFab to use even the regular FIPG as their gasket, and the stainless. Not for me though. If you are interested in a copper gasket, Summit Racing has them. Mine was about $13. For me, best gasket investment.

 

I got some Cu gasket maker and was planning on using it to mount the turbo (heard so many issues associated with the stainless gasket) but wasn't sure about the headers. They aren't bad but not exactly flat either.

Im planning on running a short 3" exhaust with one cat converter so back pressure after the turbo should be low.

 

I also have a removable cat in my exhaust system. It is a high flow one from Vibrant Performance. A ceramic core. I plan on switching that out to a nicer high flow metal core one from Magnaflow.

 

Mark,
I remember reading some information you posted that there were a couple different oil pans for the 1GR... What were they? It's easier to ask then to dig through all the info in your build.
Thx!

 

4x4 / PreRunner and the shallow, which is primarily on Xrunners, but also some base model V6's.

 

What year T4R has the 1GR? I think my donor pan came from one.

 

03+ runners have 1gr. Not sure when they stopped

 

^^^^ Correct.

 

Here is a side by side.

 

Finally took some time to pull the heads off of the engine which I purchased from DoubllD. Dan, respectfully, we see why you had problems. Even the problems which you overcame, still left more to deal with, which would have sooner or later revealed themselves.

I'll start with the pistons first, although that was the second issue we found.





It isn't very much, but they protrude above the deck. More than likely due to the machining of the deck. That fact alone, if not accounted for by increasing the thickness of the head gasket, would have raised the compression ratio from the 9.5:1 that those pistons were machined to be, to something higher. Timing could have then been too high, if it was thought that the compression was one ratio, but actually another.


Then, comes the next issue.


Whoever machined the decks, did a pitiful job. Painfully. It is no wonder you had head gasket issues. I only found one spot where I could feel no difference between the deck of the block and the edge of the sleeves, where they meet. Everywhere else, the sleeves were on a higher plane than the block. Thus there is a sealing issue that could not be avoided. I don't know if it was APR or another machine shop who did that, but any Joe could have felt that and known how bad a job was done by the machinist.






Then, there was either something going on with the tune, or a combination of trying to tune with a possible head gasket issue. As the driver side piston crowns are clearly darker than the passenger side. Let it be noted that the driver side deck had a lot worse machining than the passenger deck.

Still have further to check into the engine, but there is a good sign. The heads are in good shape. This engine will have the decks re-machined, likely one head which has a couple of tiny marks on it, and if all else is right, be back together stronger and correctly.


Also getting some work done on the turbo kit, so that I can get that back up and running at a small but safe 5 psi. Should be dropping off the truck in a few weeks to have the wastegate re-routed back into the exhaust so that it will sound much nicer to the ears. More refined, as well as look and perform better. Pics to follow as it takes place.

 

I seriously should have taken a picture, but didn't have a phone with me. When I went to Kozmic Motorsports yesterday, I brought my big ass BW 9180 EFR turbo with me. Thry wanted to see if it would fit with their current turn manifold, and what would be necessary if it didn't, on their built Evo MR engine. Popped off the Precision 6466 and the Borg Warner fit right in its place. Compressor outlet was close, still had room. It will be very cool to see what they can do with that or a slightly smaller version. They are trying to break the 1/4 mile record for that car. They have a faster trap, but can't get out of the hole fast enough. This style turbo should be able to help with that since it spools so fast.

 

Dropping tons of knowledge here, dunno what it all means but I still love reading.
