  1. Thoughts on a 2AR-FE swap kit for the Spyder?

    MR2 Spyder Main Forum
    Frank, that's exactly the problem i'm trying to solve with that tweak . The 2AR-FE controls its own fans but the 2GR-FE does not. In the MKII that isn't a problem because the A/C amplifier takes care of that for you but In the Spyder the stock ECU manages the fans. So the idea is if you are...

    The holes on either side of the wire are designed for a wire jumper to be soldered back in if something needs to be changed. The issue is jumpers are not reliable with the heat cycles and dip switches are not compatible with the conformal coating that i want to use over the whole board to...

    I think I got the production intent circuit board design wrapped up but i do have a question for you guys. I added the ability to control the coolant fans from the body controller for the 2GR-FE swaps and possibly other swaps. the 2AR-FE has integrated cooling fan control. To configure these...

    BEAN update today, Randy dropped by for some final debugging on the pre-production body controller today. The resulting video is here: The technical details for those that care. There was a scaling issue on the temperature conversion from CAN to the gauge, i fixed that. Also i had the...

    Sure, so the early version of the body controller i sent to Randy(PhatTires) had an issue completely unrelated to the software and the BEAN stuff. He plugged it in and got a no start condition which was really odd since the BEAN stuff does not affect any of that. I asked him to probe a few pins...

    That's great news on both fronts, i can't wait for people to really start enjoying the 2AR-FE
  7. 2AR-FE Swap

    I'm not surprised that the car did not gain weight because a swap generally loses enough other stuff that it can easily make up for a slightly heavier engine but 45lbs of loss does actually surprise me but that's awesome to hear. I'm surprised you noticed much in the way of extra vibrations...

    Dave, I have to apologize on that one. I hadn't ever looked deeply into direct injection and i had it in my mind that injection happened immediately ahead of the ignition but i never thought much about it. But your message spurred me to look a bit into it and it of course makes sense that the...

    The extra power came from a few different things. The biggest one is just opening up the exhaust, before i could modify the ECU i was getting a bit over 190rwhp just with the exhaust alone. beyond that the velocity stack style MAF tube really helped and then just as you said, leaning out the top...

    That's the "I don't want to mess with it, just order it on e-bay and have it show up to my house" price. The transmissions are starting to show up at pick & pulls and the engines are all over the pick & pulls. If you get it there and pull them yourself you'll be in for about $400-500 total on a...

    Officially, the donor should be the 2011-2016 Scion tC because that's the transmission and wiring harness you need. You can use a different harness if you're comfortable with the work that entails, i won't be giving a pinout for any other harness in the near future, but the harness is $550 new...

    Yeah and it feels pretty good when driving it. you get good power without always needing to rev the absolute heck out of it.

    Part of the rarity of the MKIII is because they only made about 30k or so for the USA where the MKII got about 130k for the USA. But a bit of patient looking will allow you to find one. As for comparing them, the re's no way you can ever make something that everyone thinks is a fair...

    Huge step today, the junction box is now available for sale: https://frankensteinmotorworks.squarespace.com/mr2-spyder-shop The BEAN code is now fully functional but i want to do more testing before releasing it. Also, there's a wire at the wrong place so I have to run yet another circuit board...

    The 2.7L crankshaft is actually from the 1AR-FE which is identical externally to the 2AR-FE so you can swap the whole motor in. Right from Toyota that motor comes with a pair of balance shafts so if you intend on street driving it there's no problems there. Also, if you do some reading about...

    Considering manufacturers usually take a different route and make a custom part for this application I'm thrilled that Toyota just rotated it instead. Now we have access to way more different part numbers of coils and are way more likely to have performance coils made for this thing. The reason...

    I went looking for videos and apparently i did not remember 100% properly. it looks like they run to 9000, not 9500RPM. This video shows exactly how much goes into a 2AR to spin it to 9000RPM and make 1007hp:

    Wiring harnesses are finally available for sale: https://frankensteinmotorworks.squarespace.com/mr2-spyder-shop/2ar-fe-wiring-harness Junction box will be available by the end of the week ($50) and body control to follow really soon ($150) After this is done I'll tackle the custom reduced...

    That's really unfortunate and may explain why the traffic to this thread has really died. Maybe it's time to move this thread to a new one then if very few are subscribed to this one anymore. Is anyone else getting notifications of this thread being posted to that hasn't re-subscribed to it...
