Motor swap thread

it's not THAT big... I didn't look at the trim though. I have a 57 trim on my Mazda and that's a 2.2 sohc. starts to pull hard at 3200rpm. love it.

oh yeah something I thought I'd mention about sv's build... its not built for horsepower! he wouldn't have the RV head or cam if it was.

Yeah dude, it takes quite a bit to get that big sucker spinning lol. Also with 750cc injectors you can hang up getting good mpgs under boost :reddance:

Sorry for hijacking Kids thread

Nah, hijack away. I know next to nothing about turbos.

Basically...
A small turbo will spool up faster and at lower RPMs producing power faster. This power will not continue to build as the RPMs go up.

A large turbo will have little to no power increase at low RPMs and require higher RPMs to notice added power. Once this power starts, it increases as the RPMs go up. The sheer mass of the turbo takes more time to get it spinning.

Twin turbo, best of both.

Variable vein turbo, best of both. Same as a twin turbo (maybe better since it constantly changes virtual turbo size). May require a larger displacement motor to produce enough exhaust.

He said it perfectly.

I've been considering this as a viable solution when my 22re gives up. Sure, i could just spend $400 and relatively few hours putting another 22re in, but where's the fun in that? From what i've gathered, the 3rz, as it comes mated to a W59, will accept a W56, is easy to mount, relatively easy to wire, and does everything moderately better than a 22re.

How many man hours would you say your swap took? And what surprise expenses came up? I was figuring i could do this for $1000 or under, if i got the motor for ~$4-800.

I view the 22re (and IFS) as the weak points of my yota, i feel like with a SAS and different engine, i'd never be able to get rid of her.

I haven't started the swap yet, my original R series engines refuse to die as long as I maintain them.
