- Tue Jan 05, 2010 4:53 pm #165959 ok so with the high miles my car has i have been thinking of swapping it. But i need something reliable. Now i hear alot of bad things and alot of good things about b20vtec. i kno if done right its a badass swap. I dont plan on doing to much to it i jus want a decent amount of power. So i was wondering if i got b20 with like 80xx miles on it and got a b16 head and wasnt cheap about the swap and got all the right parts needed will it b reliable stock. Or will it b a headache to swap it in to my ej1. Would like to hear from people who have done the swap already please.

Just a lil something to keep in mind.......the B20 block has 33% thinner cylinder walls than other B series motors.

I'd just do an H series and call it a day.

Like Mike said, use the right parts, do it right, and don't cut corners. The engine will bolt straight in with no fitment problems. There are several threads on this site that outline the bare minimum parts necessary for a proper LS/VTEC or B20/VTEC swap into the EG chassis.

As for the H swap. Im not a big fan of it, but a H2B is a easy swap and makes some nice power.
