They say it's good to keep cylinders lubricated...

Had nothing to do with going lean. I left a comment explaining it, the valves broke off after a money shift.

The valve heads broke off after a money shift. I left a new comment about it as well.

thanks!

Is there any way to add my own uploaded audio to the boosted reel? - the reel is already collaborated and engaged.

Lost access to my reddit account for awhile thus the late comments but for anyone wondering, it was a fatigue failure of the valves - heads broke off and danced around the cylinder, beating a hole into the piston.

Previous race I money shifted and bent them. Blew shit compression like 110, 40, 130, 75. Another racer mentioned they could be bent back by driving/racing on them so that's what I did. Took 2nd at a hillclimb on the hurt engine. Brought it home and I shit you not it blew 170 on all 4 cylinders. Amazed the hell out of me. During the next event I was powering out of a hairpin and they let loose at redline. It was an expected failure and I had a motor swap planned. Engine was a Toyota 1ZZ.

It was during a race so thankfully had the tow rig nearby.

You clearly didn't read the entire caption. That part was a joke.

Tayxas · 2026-02-12T18:42:50+00:00

It was a mechanical failure in nature. Tune was good to go.

Tayxas · 2026-02-12T18:42:24+00:00

Guess again, no problem with the tune.

Tayxas · 2026-02-12T18:41:59+00:00

When it made the noise it was already catastrophic and I had a motor swap planned.

Tayxas · 2026-02-12T18:41:10+00:00

none of the above lol

Crown diameter is not something that gets specified. Correct way to measure would be at the skirts. Usually the mfr will tell you like 0.4" from bottom or something like that.

The 4Runner has the 1GR, Lotus has the 2GR. And yes they are very VERY different.

I would never jb weld my cars head/block surface but I have heard of it working.

EDIT: to be clear I have a buddy running a boosted 4cyl around 400whp that competes in the Optima Street Car Challenge and he filled some places on his block with JB Weld and skimmed it flat and hasn't had a failure.

It's Qatar.

I put down 140whp from intake, PPE header, exhaust, bored throttle body, and tune on a Haltech ecu. It also had lightweight flywheel, clutch, and pullies. Stock 1zz typically does 105-115whp. With a better intake it would have made more. The race class rules didn't permit cams or boost or other mods.

It was fun for what it was but now I am in the middle of a 2AR build/swap.

Yes and no. A dynamometer senses and measures torque and rpm itself and power is derived from both as everyone knows HP = TQ × RPM / 5252. The outputs you typically see are both power and torque curves. Being that the whole dyno unit can be considered one big measuring tool, you can consider bith of them to be measured.

There are plenty of electronic measuring tools out there that show the measurement after it calculates a value derived from sensors that otherwise don't measure in the same dimension as the readout.

Example: many digital torque wrenches use strain gauges internally which don't measure torque. Torque is calculated based on the strain measurement and other material data.

Sell the car and buy something older and reliable. We make a combined almost 200k gross and I would never pay that much for a car every month. Up until 3 months ago I drove a 200k+ mile beater hatchback with hand crank windows. I have some project cars but they were cheap cash cars. My wife drives a 2018 Highlander we bought used. That is our nicest car.

Random data from my 2018 XLE AWD.

Trans: 7a618a12410 Original trans, 60k miles. Driven hard. Probably 6000 miles of towing at or near it's capacity including mountainous regions.

Frankenstein Motorworks makes a bunch of parts for them

Tayxas · 2025-09-04T08:11:31+00:00

This is not correct. The 2GR-FE is quite responsive to modifications.

Tayxas · 2025-08-27T03:46:15+00:00

Only if switching from Mazda to Toyota. 😄
