you are awesome. I've been looking and totally not finding.

I'm not sure. I saw that Toyota used a 51R battery in a special JDM racing model. It might have had a name like "Griffin" or "Phoenix" or something like that.

My 51R battery is still chugging away.

I ended up getting a Deka ETX15L. I'd used a Braille 14115 previously.

I 3D printed a spacer to center/hold it within the stock battery tray and raise it up just a little so I could use the stock tie-down. Also 3D printed a block to fit around the curved part of the stock hold down and to spread the load out over a wider area.

Seems to work well - I'd done something similar with the Braille and it held up through 2 HPDE seasons and was going fine when I traded the car.

The deka was way cheaper than the braille. $80 all in with the terminal adapters.

Deka 11.8 lbs with mounting hardware.

Nine years now, worked like a charm when I put it back in the car for this season, but a slightly slower crank.

Until, I forgot my oft plugged in for 5 days.

The charger became recalcitrant swapping into charge mode , after 24 hrs. the charger would still not go into charge mode, but it eventually went into store mode.
Will report on reliability, after a long one of these - :burnrubber:

Sixth year tracking and D/D, Shorai 5 lb. battery still going strong !


:confused0068: Working normally now ! - Don't know about next winter, I may have to retire it for the season a little earlier ! :D

Just got this for my track car, and I have been running the same format Lead/acid battery with less CCA for almost 2 years now.

10 years tracking and as a DD, that damn little booger battery still goin strong !
As is the built block and supercharger, :D amazing!
:confused0068:

how did you fit it and secure it in your car? I really want to dump that huge stock battery, but I don't want to half -ass the install.

its been relocated to the top of the transmission tunnel under the dash in a gutted car.
