Great post! That should answer a lot of people's questions!

a) Is the CNC'd custom second gear sprag replacing the one that normally takes a shit at HP over 600+?

b) You didn't list it, but I assume the CNC'd sprag is also included in Stage 3.

c) Any idea on HP level maximums of the Stage 3?

[Ryan23]

Nice to see everything broken down, Larry. What do you see as the max power threshold of a stage III? Is there a converter out there that is equally as stout? I have a pair of HKS twins I'm considering upgrading to GT30's for my SC. I already have the drivetrain out of an auto TT, so I would prefer to use what I already have. Do you think a pair of GT30's with say a 75 shot would be taxing a stage III, assuming cooling is addressed?

Thanks,

Ryan

AGREED!!!

[supra213]

what's the HP level maximums on all 3 stages respectively

[supralover93]

is there a warranty offered with the stage 1? how well would the stage 1 handle the budget kit?
thanks

[FYRARMS]

Larry, stop browsing porn sites and answer our questions, you bastard.

[Sound Performance]

thanks

Stage 1 and 2 are only offered with a 30 day warranty. Any stage wil handle the budget kit fine.

There is no way to put any HP level on these trannys. I can tell you that it will be as strong as any built Toyota tranny out there. If you think that a Toyota tranny will be 100 % reliable at 750+ RWHP you are kidding yourself. Do not be fooled by other tranny company's advertising.... I get calls from people with broken trannys from EVERY manufacturer or Toyota trannys out there. In fact just got one today from a guy who went through two from a very reputable tranny builder..... then he brought it to a local tranny repair shop and found out it was 99.9% stock on the inside.


If you have a single turbo and you want 100% reliability, there is only one option...... and it is not a Toyota tranny.

Cmon Larry..give us a lil something. Will the stage 3 will be at least good enough for 700rwhp and below? I mean, at least it would blow after a few good passes at the track? Most of us just want to do a few track runs maybe once or twice a month and have the tranny hold for that and daily driving.
How about this? Give us a recommended max turbo size for each stage.

[1A1]

I don't drag race much at all, if any, but would rather not put a 400 in my car. It would be nice if you could put a max hp or sized turbo for each stage.

It is not possible to rate a max HP on these trannies!! I have seen people break them at BPU and I have seen guys with 800 RWHP make them last for a full season.... There are too many variable... driver style, tires.... etc

A car with sticky tires is much more likely to break a tranny as well as a heavier car. Im not gonna lie to you guys and say it will handle 750 RWHP like other companies.... only have you call later and say it broke at 500. I get those calls about other companies way too often. If youre gonna keep the Toyota tranny.... you are rolling the dice. So do you feel lucky?

Can the Stage 1 Upgrade fit an MKIII?

[Silver Orchid SP60]

If thats the case then why bother making the different stages since they all are basically a crap shoot? In other words dont go single with the auto unless you want to run a TH400.

^^^^^^^^^
What he said. Also need price of your SP58 turbo upgrade...

The key to making them last is how you drive on the street. It is obvious how you will drive it on the track, but if you also drive it like that on the street - full power upshifts, etc - that is where you are pushing it!

You can enjoy an auto Supra on the street without a single full throttle upshift! 2nd gear will take you from 30-90, 3rd gear will take you from 50-130.

Yes we can also upgrade MKIII trannys.

To hit diff price points.... Stage one is the basic upgrade while three is the complete rebuild also. Stage two offers the sprag upgrade.

He is 100% correct!

Quick question since I will definately be doing the tranny this winter...which stage directly compares to boost logic's tranny upgrade?

stage 1

[j0hnyboi]

How much power will stage one tranny support with a 3200 stall? Also, is this comparable to BL's $1800 built auto? I believe BL rebuilds the tranny though.

[supra8388]

in your website you only list $3400 for MKIV. Which stage is that? How much is stage 1 upgrade?

[j0hnyboi]

I just want to run 400rwhp all day long, no more and no less. Now which stage would you recommend? I will use a 3200 stall with a fat ass transcooler.

If you're going to take the trouble of pulling the tranny out of the car and rebuilding it, I would go with the Stage 3. The only reason in my mind that anyone would go with the lesser stages is if they just can't afford them.
