Looking for A Turbo 400?

[Highlimit9000]

This will be for the 22 Schiada...Approx 1000-1100 Ponies...This is what CP Quoted Me through ART Carr I guess...Cant believe $600.00 for Polishing!Is this un-reasonable? If I find a case I bet I can get it polished for $100-200 in Vegas.. Then get it built for less with all the good goodies..What Numbers should I look for on T400 Cases? Anyone have any advise...Thanks John...

I can't believe 1700.00 just for the Turbo 400... :2purples:
They aren't exactly rare, so you should be able to find one. Just make sure you get a Chevy bolt pattern and not a BOP bolt pattern and you'll be good to go.

I've got one, however it's not polished, but it does come in a handy 21' carrying case. :D
To build and beef up a Turbo 400 (do you have an exchange or is this your tranny or is Art providing everything from scratch?) that doesn't sound all that unreasonable. As far as $600 for polishing the case, take a look at it, there are lots of little nooks and crannys to get to make it look nice, not to mention, most the tranny cases I've seen will require lots of work and time to get them cut down to a place where they can be shined up.
I think I was was going to do it, I'd have Art do it, pay the money and not look back as from what I've seen he knows his stuff and can charge more than a Midas transmission based upon that. Kind of like having Peto build you an engine. Yeah, you're going to pay more than you would for a long block at Autozone, but you're getting more at the same time. I wouldn't skimp in this department, but that's just me. ;)

ya know - this was my first tranny boat - what do they exsactly do diffent than a car ? i was checking trannies out at jegs and summit - with reverse pattern manual shift - 900-1100- the only thing i would think that would be diffeent would be pan and a pick up ? but i have never had my pan off so i do not know ?

[Jordy]

I think like anything else, you'd have to change some stuff out and do some beefing up for it to live with 1000 hp or so. That is, I wouldn't hold a lot of hope on something designed for a 300 hp small block in a truck to last behind 1000 hp in a boat.

no these where worked trannies :D

no these where worked trannies :D
I'm looking at the latest Summit right now. Page 183. B&M wants $1000 for a Turbo 400, don't see a power rating, but the others are rated for 450 ft. lbs. That one won't cut it.
Next, Summit's Turbo 400. Good for up to 450hp. $725.00 Not quite enough. TCI Street Fighter Turbo 400. Good for up to 450 hp. $790.00
Wait, here's one rated for 1.250 HP. But it's a Powerglide, built by Hughes. Two choices in length, cheapest is $3769.00. They offer a TH-400 but don't give HP ratings for $979. Going to go out on a limb and suggest it's not rated for 1100 hp.
Cut corners to save money, then have to buy it twice and where are you? :D

[schiada96]

I took a rebuilt t400 added a reverse pattern tci valve body. It is fine so far for 4 seasons. I'm running the hughes pro converter eliminator. The Art Carr spline drive is the way to go just use the blower drive plate not the cheep one. I think Rex would be less expensive for the drive and plate. Lots of trany builders can handle what you request. We are not going to launch a 3400 lb drag car. I'm not making 1100 hp but I'm making a lot of torque. I would think you could be set up for $1500 less polish.

Ok, has anyone thought about putting a scatter sheild on their trans??
The only thing between the trans and someones ass in a little plywood and some foam. I've been thinking of fabbing up some kind of sexy scatter sheild. Am I worring for not here?

actually - the front of my engine cover is 1/8 alum- and the removable center floor is also 1/8 and wood ( if it blew it would still fly off ) lol
what about a tranny blanket - hey jordy - check jegs and look at the tci trannies - you would want the one with the reverse pattern and no trans brake - anything above 1200 and your looking at deadenbear p/g

I will start off by saying I don't know squat about v-drives, except they are expensive. Second I will say that I have TH400 in a blazer with 36's and a Offroad Design twin transfercase setup all behind a fuel injected 454. My drive ratios is as follows:
Trans Low 1.76:1
NP203 - 2.01:1
NP205 - 1.96:1
Axles - 5.13 w/spools
for a final drive ratio of 35.6 (remember this is an automatic). My blazer weighs in at 4800#'s and my engine puts out a conservative 500 HP. My point being is that my trans is a stocker that I pulled out of the junk yard and I have punished this trans really, really hard (I do everything from rockcrawling, to glamis, to mud) and I haven't been able to bust the trans yet. The TH400 is a strong trans. I don't think you need a 1100 HP rated trans in a boat since there is never any direct hard starts on the trans, there is always lots of slippage between the prop and water or at least there was on my old nordic. Also there should be a good shop in your area that build a trans to your needs for cheap.

you said it , so you just did - I hope not - dam carma lol -- ohh by the way i totaly agree with you - the prop is a torque converter and slips .. no bite

SD , CSR formerly CSI has a bad ass carbon fiber shield .Meets SFI spec for trans shield and flexplate shield ,looks cool and fits tight to the case .I think I paid around 300.for it. Bob

I'm kinda surprised by the pricing of a marine TH400, I have a nice polished TH400 in mine, supposedly an Art Carr, reverse manual valve body, no park sprague and hooked direct to engine (my prop is the best converter I've ever had). I don't know much about these, but I'd be happy to share pics or part numbers if it helps in any way. I would also highly recommend the B&M pro-ratchet shifter, very simple and sturdy.

[jet4fun]

i would talk to fastsanger here on the boards. i believe he has a t-400 from mike's transmission in palmdale, they build drag racing trannys and he has his in a 21 daytona v-drive

Corleon 17,
As far as the polishing cost, that's not too unreasonable. I should be able to get it polished for a little less. The trans can be modified to handle the power your looking for. Usually the rebuild cost is around $7 hundred dollars not including hard parts. We can deal with the spline drive and spacers when we bolt the trans to the engine. Look for a "take out" or one that needs a rebuild or if you'd like I can find one for you. Don't forget your going to need a cooler for that thing, but we can handle that also. Let me know if you need anything.
Good Luck,
Mike @ primemarine

P.S. I think I may have a polished TH400 all ready to go. It might just take
some convincing to make it yours!

There ya go just buy that one.
Watch the spacer thickness with a blower plate.

[repo man]

my dad gets converters that are welded solid insted of the adapter.they're cool because you get the extra gallon of fluid. my brother is running one in a 21' rayson craft with a 1471 blown entercooled 572 without any problems.

[Highlimit9000]

Thanks for all the input Guys! I think I found a case from BoatAnchor already polished. I already have a cooler for the Tranny. Will still need the Spline drive and drive plate though. Probably get that from Mike at Rex. I am gonna do some checking around Vegas for some tranny builders...If I cant find any, will defenitiely go to Cali to have it done...On a different note...I get the Schiada Back on Tuesday..Hopefully have some Pics before then...Fiberglass Reformations said it turned out great! Mike at Prime...Your shop will be next! Still waiting on Rudder, Strut and V-Drive...Thanks again for the input....John
