Happy 2017! Well, it's time for a new project and for my car to start the 4th of it's 9 lives. It's turbo K20 time!
Here's some brief background:
1) I got my car, and it was awesome
The culprit was identified as a fragged oil pump
. 8500rpm + 400hp + time on those sintered gears and all hell broke loose. Just to be clear: this was not a failure of the BOE REV400 kit. This was a Toyota part failure, which was likely exacerbated by the power of the car. If anyone is going to do more power than a BOE REV300 kit and start building a 2ZZ motor, please make sure you address this. I _really_ wish it had been taken care of on mine. I'd be happy to still be driving a 2ZZ motor.
After weighing my options for a motor replacement, I decided I did not want to go in for the time and expense of another built motor. This is supposed to be a street/track fun car for me, not a world-record beater, and I wanted to avoid the expense and one-off nature of a built motor. If (when?) I blow the next motor in the car, I'd like to just pull it and replace it with a core, so I had a decision to make: stay with 2ZZ and detune, or move to something else. I made the decision to go with a Honda K20A2.
I'm using a Honda K20A2 from a 2002 Acura RSX-S. I was able to source a complete motor, transmission, wiring, and ECU setup from a running, non-molested car that was going under the knife for a different motor swap. Anticipating putting down some serious power, I'm going to upgrade the transmission by adding a Wavetrac LSD, and a slower final drive ratio from Gear-X. To hold the power I'm using a Competition Clutch Stage 5 sprung clutch and their matching 8lb Ultra Lightweight Flywheel.
Fueling is going to be setup for flex-fuel, tuned for 93 pump and E85. I've sourced some ID2000-equivalent Bosch injectors built and flowed by a nearby speed shop. I've never had a flexfuel car before and am excited for the possibilities of E85 blends in the turbo. The power numbers people are making on stock K20 blocks with this setup are insane, over 600whp. I will not be shooting for something quite that high.
For motor and transmission mounts, I've sourced the Innovative Mounts K20 engine mounts, as well as the transmission axles and shifter linkages.
For pure fun factor and "while you're there", I've also added in an AliTech shifter in black and silver. I can't wait to use this thing!
Much of the above information I've already posted publicly in a couple different threads, but since the motor setup is underway I thought it would be useful to start putting all of this in 1 place for everyone to see, and make it easier and more succinct to add updates as it goes along.
Please feel free to comment, give suggestions, add critiques, ask questions, or whatever! I want to document the blood and guts of a Honda swap, as there aren't too many done in the US.
