Re: F20b swap! After f23 blew up 😭

I like how I posted this and everyone thinks Iím gonna spin a bearing... does anyone know how to check clearances?? Iím sure Iíll blow a compression ring first but thatís what my water meth kit is gonna help reduce the chance off lol... thanks to the people that said good luck and cool swap.

Update:
New poly mounts installed 95a ( shakes a lot!!! )
New Hondata 4 bar arrived
Boost pipes hooked up
Gonna be timing it tomorrow after I figure out vtec issue.. donít feel vtec engaging.. whatís vtec for the f20B??

Re: F20b swap! After f23 blew up 😭

I never said anything about thinking you are gonna spin a bearing just how did it happen?

Hope the build goes well. I have hit the limiter in my 5.7 tundra while shifting manually. It was a little before the 6k redline. Made me sad I couldn't touch that line.

Re: F20b swap! After f23 blew up 😭

On my previous setup I didn’t spin a rod bearing, the piston actually cracked. I’m assuming a ringland broke

Re: F20b swap! After f23 blew up 😭

Is vtec engaging? Most of the vtec engines feel this way if its not engaging. I had that issue with the f23 and the f20b. You can usually tell when itís not engaging by the sound.

Re: F20b swap! After f23 blew up 😭

Alrighty then update time:
My car has turned into a major pain in butt!! Okay so the first F20b engine blew up 🙁.. it blew up after the second pull on at 6psi. Cylinder 4 ringland blew apart.

Fast forward 5 weeks, ordered a fresh f20b from hmo.. super excited and installed it within the next couple days also ordered a new precision 5531 for the new engine. Got the engine installed and ready to do some pulls.. boom again cylinder 4 blows apart again!!! Same exact issue!! Ringland blew apart. Okay now Iím like okay we have a problem either on distributor side or injector.. come to find out I had 2 problems. First problem, the first engine came with a 9 wire distributor and second f20b came with a 8 wire distributor.. so I wired in the new distributor after putting in the second f20b back with a new piston and new rings. Drove the car with no boost first!! Car was absolutely gutless (vtec was engaging ) so I brought my tuner over, maybe it was something in the tune.. he set ignition timing and took it for a spin... long story short my ignition timing was so far out and my tuner didnít adjust it correctly and was so far advanced that It felt like it had maybe 80hp.... fixed the ignition timing and boom! Pulled like a true dohc vtec engine!! Well I get it back to my house all excited and just talking to my neighbor while the car was running and boom! Radiator explodes, engine over heated... come to find out when the tuner changed maps he never turned on the fan temp to activate! So it might of blown the head gasket cause my Hondata read 240ē before it blew the radiator!! So Iíll be giving a update soon! Anyone wanna add me on fb? I post more things on there then I do on here lol

Re: F20b swap! After f23 blew up 😭

You have terrible luck with this motor this is why I wouldnít boost it without changing out the pistons and rings. Theyíre good to begin with but for how much you spent you could have gone forged internals and got a good tune although it seems to be more minor issues causing the engine to explode lol. I would definitely make that tuner pay for a new engine. This is the major reason I have gone to any tuners in my area. When I move to Florida I know Iíll have to get it tuned because if the massive elevation difference but I can get that done by a reputable tuner in like Orlando or something. So are you trying to save this motor or going to just get another?
