box k20

I'm hoping the moderators will allow this here as there are folks on or associated with this forum that have had a part in this build. I've been working on this car on and off for the last 6 years. I've done almost all of the work myself, even the poor paint job. This is the first car I've...

This cable stop requires the TB bobbin drilled a hair larger, but makes for a clean installation. Old ratty cable is my retainer so I don't loose it- this thing is SMALL and pricy for what it is. Quick disconnect makes it simple to keep your stock spring setup. Ensuring the pedal assembly...

Has anyone used an RBC manifold on their Swap? I have been searching and found an old thread by Tim Hoover but it seemed to just trail off and it wasn't clear if it worked or not.

Well I thought I might start posting up some pics and information on my K20 swap. K20a3 motor, K20a2 head, K20z1 cams.

EDIT (Aug 2019): K24 Install Thread Here Page 2, 3 Aug 2018 - drivetrain arrives, thermostat, extension housing and piping layout. Page 4 - thermostat ext, intake & plenum layout Page 5 - plenum & TB layout Page 6 - water housing, coolant pipe, Plenum welding Page 7 - oil pressure sender...

So I always had planned on doing a 'proper' posting for my k20/restomod build but even tho my day job is in the software industry, I just never seem to find the time to do it right. My plan was to follow Rodger's previous advice on posting and do proper postings. I think at this point I need...

Does anyone have any good pics of how much i need to cut out so i can shoehorn a k20 motor into my X? Thx Patrick

Well, I was pretty bummed when the Photobucket debacle happened as my entire K20 build thread is now pretty useless with no photos. It would take me forever to reload them all, but that is a project for another life. Anyway, I figured I would continue with my progress in a new thread. Once I...

As part of my overall K20 swap project, I am doing a full shell up restoration of my '81. I acquired a late model Bertone fuse box and most of the wiring harness a few years ago and my plan is to use that for the new wiring harness for my project. Whoever harvested the harness was in a hurry...

As part of my K20 swap, the instrument cluster needed to be modified to accommodate an electronic speedometer. Many thanks to Bob Brown for information and advice that he generously shared with me as I was attempting this. He was the one that developed the idea of using Marshall gauges to...

Part I I have been working on my K20 Swap for about a year and a half and am near completion. I have been driving the car for about three weeks and am just working out a few kinks here and there. When I saw the first Midwest Bayless K20 swap I was amazed and intrigued in that it was the...

Are any of you using an RBC intake manifold? (vs. PRB that comes stock on the k20a2) Here is a comparison: RBC on the left... The RBC is stock for US Civic Si. The 15hp increase, pretty substantiated claims are out there from what I have read and discussed with my tuner. I think it...

Epilogue, February 2, 2021. This thread documents my 5 1/2 year journey to do a K20 swap on a 1981 Fiat X1/9. It didn't start out to be that, but it turned out to be a great adventure. I learned a ton about automotive repair, restoration, and fabrication along the way. This thread is part 1...
