(Engine Trashed?) Thread of Unfortunate Events

What's more interesting to me is that when I go and look at used Tacoma motors on eBay, the block says 2GR. So I wonder what the difference is between what comes factory and what you received?

Did you purchase 11400-31400?

I'm not worried about fitment, I'm just curious what the actual differences are. The Tacoma 2GR and the 7GR are supposed to have essentially the same block, but it gets more interesting when they have different model numbers cast into them. Makes you think things are different.

 

It's just a matter of time. The 3rd gen engines are surprisingly high compression. Couple that with forced induction and it can spell disaster if not properly tuned and timing dialed back. You were likely detonating. Ask me how I know.

Did you get a custom tune or did you use the off the shelf tune?

 

Tune Tester for Yotawerx...didn't work out lol

 

Solid progress for a Friday.

 

Ahh, lol. Did they hook you up to a dyno and use a A/F meter? Sounds like it was just an off the shelf tune.

 

Nope, the prochargers were fairly new at the time on these trucks and they modified a maggy supercharger tune and pushed it to a few guys who signed up to be their guinea pig - I was one of those suckers. They claim everyone else was fine but maybe I was the only manual and they screwed something up idk. They also performed a dyno tune on a truck and changed the tune "drastically" but never updated me lmao.

 

11400-31400 is correct. That's what I ordered. My old short block also shows "2GR" from 2019 build. Kinda strange lol

 

They should compensate you with a little R&D money.

 

Looks like 11400-31400 replaced 11400-0P100…wonder if the 0P100 was the 2GR block and it simply doesn’t matter?

The 7GR makes a bit more torque and HP than us, but that’s gotta be programming because the bore and stroke is the same. No way can I think of a short block contributing to any of that. It ought to work just fine, but definitely odd how they consolidated parts like that and are now giving us the 7GR block.

 

Hell yeah, this makes me want to wrench on something.

 

Cam housings, timing and timing cover

Timing cover and hoping you did the timing correctly has my anxiety through the roof.

Have about 10hrs to go through to make a fairly simple walk through. Going to make sure the truck runs before posting though heh.

 

Spin by hand to verify marks.

 

Correct me if I'm wrong but once you set all the marks you have to rotate the crank twice for them all to line back up? And the chain won't line back up for many rotations? The chain is what was throwing me off but after a few rotations the bank 1 and bank 2 cam sprockets and crank sprocket all lined up again.

 

You need to rotate the crankshaft like 50 times to get chain marks line up

 

Do you have to have cylinder 1 at top dead center or just line the sprockets up? The proceedures didn't mention having cylinder 1 at TDC, if so, I'll have to redo the time tomorrow.

 

Cylinder 1 must be in tdc. Crankshaft mark should be in tdc

 

Crank shaft mark was in the correct location but I didn't verify that cyl 1 was physically at top dead center...oof. I'll watch the pistons from the bottom and see if it's in TDC when the marks like up.

 

You should be fine if crankshaft mark was in tdc

 

Just double checked, spun the engine upside down and looked at the pistons from the crank area. When I put on the valve cover I had the marks lined up and I slowly turned the crank and cyl one piston started to come down so yeah, I should be in time...phew had me worried lol

 

Next important item to install the relactor wheel correctly.
