Hi guys
I've been wondering - has anyone ever explored the Auto transmission on the B series cars for Drag Racing.
I know the Neon's and some GM Ecotec's have run the Auto's with good success.
Is there a viable option for high HP Turbo Drag Honda's or is the B series auto just not capable ??

are you going with the eco tech trans? i no there is a place that makes the bell housing and that trans is a beast! i was reading up on a artical a couple years ago on how to build one and it was pretty sick how cheap you could do it for. but i do wander if the rules would allow a gm trans in a honda chassis?

call it a dead horse if you want but the day someone gets a honda auto tranny to hold its over for manual transmissions. they have been proven to be faster time and time again.
also what are the rules in the outlaw class regarding transmissions from other manufacturers as an example can we use an ecotec trans?
the billet housings are copies of the stock housing, and bolt up clean and clear. big difference between taking a completely different design and making it mount up somehow. an auto trans that works for b series will have to be something other than honda based.
Totally agree with you, I know i would buy one. Just seems like a million different people "have had something in the works" for the past 5 years. Not doubting you i hope you come up with something, just saying.

Dude.. If your heart is in it.. then I say go for it! I am sure the same people saying that it can't be done.. were the same ones saying you can't turbo a honda engine 20 years ago. IMO opinion... look at auto tranny's that are holding 700-1000 WHP.. and see what components they are using.. material, size, etc.. and see what you could stuff into your box. Unfortunately, a lot of companies that build racing auto tranny's have not done one or have not found a customer to be the "guinea pig" for that type of tranny. That is why they cant make claims of HP gained or withstand... but your in South Africa.. just kick over some dirt and find those diamonds... spend lots of money and R&D.. and then come back to HT so we less imaginative people can praise you for something that would seem so simple 5 years from now. FYI those domestic cars running in hotrod a few years ago.. are actually 1/2 million $$$ cars that nearly killed sport compact racing... i mean Import Racing! lol
so it was easy money pouring into those transmissions.
Nobody will know untill they try. I have an Automatic AWD Mitsubishi Mirage. There are DSMs running mid to low 9s on stock automatic junkyard trannies. A few years ago, nobody thought this was a good option and nobody thought it would hold the power. We use a simple wiring method using some diodes to make it full manual using a BM ratchet shifter.

H2B's dont just bolt up.
I'm not familiar with the B motor, but I'm running a Honda J motor
Coupled to a powerglide. I'm only about a dozen runs into it and have had success as well as issues. Your number one enemy will be heat, so get creative on cooling the oil. Generally, anything over 190F and you possibly will be toast. I got creative and the hottest I've seen is 120ish. No bullish$t. My tranny has a reworked valve body that does some magic. My experience is that you need nitrous to spool the turbo, some may argue with me on this one, but a tight converter is also a must. With that here is the problem, hitting it with enough nitrous to get to your desired launch RPM without delay and still run a tight converter, valve body holds the answer.
Data log shows anywhere between 8 and 15% slippage. That's not ideal but I still haven't thrown all the boost into it which may tighten it up a little. Another thought is a 2 speed isn't enough gears it seems, but the juror is still out on that one for me. I've already changed the read end gear as I was running out gear by the 1000' mark with at only 20 psi and launching at 20 psi as well.
You'll have issues ifyou try it as have I. I'm not quite at the end of my rope as I'm so far into it, that it only makes sense to exhaust all ideas. But here's the ultimate setup, Bruno-drive with a Liberty 5 speed. That won't work for u as ur FWD.
Just sayin...
