2.7l has low power after rebuild.

Just buttoned up a rebuild on my 2tr-fe. Had a machine shop build my short block and I did the rest.

Starts up and runs well. Very smooth. Zero codes.

Issue I’m having is while driving it feels like I have about 60% power, especially when the revs get to around 3k or higher. Haven’t really been able to get it revved higher than 3500.

First thing I’ll check once I’m home (from work) is compression and fuel. Any idea what else it could be? Thinking it might be timing, but that’s not something I’m very familiar with.

Thanks.

 

Check your coils for cracks if the compression is good

 

Cracks in the plastic body? Had a pretty good look over them when I cleaned them before popping them back in and didn’t see anything.

 

Are you sure you're not a tooth off on the timing chain/sprockets?

Been there, done that on an Audi. It it started and ran but was WAY down on power and wouldn't rev.

 

My 4 banger always feels like it is at 60% power. The motor just doesn't make much power to begin with.

 

But it should still make 100% of its power to begin with lol

 

Yea, just saying it's so slow that I probably wouldn't notice if it wasn't making 100% power cause it always feels under powered.

 

My nephew has the same problem with his old 2.4 Tacoma. He had a local mechanic replace the head gasket, & since then it has only appx. 60% power. They've checked everything they can think of, but still haven't found problem. Hope you figure it out, for you & my nephew. Good luck.

 

Slow for sure. But 60% of the slow 100% I drove for 10 years. Very noticeable.

Most of the power loss I notice after 3k. Under that is close to normal.

 

In my memory I’m pretty sure it’s bang on. This is definitely a possibility though. Will likely pull the valve cover if everything else checks out.

 

I wish my 4cyl ripped that hard.

 

Improper cam timing will absolutely kill power. Definitely check it out.

 

Did the exact same on my 22R-E. Even bought an LCE adjustable cam sprocket thinking I needed it but just needed to set it right.

 

Anyone know of there’s any way to check the crank sprocket for alignment without removing the timing cover?

 

How many miles have you put on the engine? It might take some time for the engine to fully seal. You worked it to get the rings to seat and aren't being too gentle on it?

 

Maybe 50 today and yesterday. Trying to drive it hard but engine doesn’t want to rev above 3500 so it’s a little tough.

 

Quit driving it, your valve timing is off. I guarantee it.

 

Roger. Will tear into it tomorrow.

 

Is there anything "tricky" or odd about getting the cam timing right on the 22R, my nephew said his mechanic has rechecked it twice & all is correct.
