t56 question
 

so im pretty sure this wont work but id figure id ask anyways, i found a t56 out of a camaro fairly cheap, will this work in my mustang just as a t56 out of a cobra?

you've gotta swap the bell housing at a minimum and tail shafts i believe. you'll also need to do some wiring, get a new driveshaft and you'll lose a ton of time since its probably a 2.66 first gear T56 and not a 3.33 like a 5-speed mustang has. stock cobra T56 has a 2.97 first gear.

T56 for GM and ford are very different.

oh ok, im not gonna bother with it then. im debating on buying the promotionperformance 700hp t45 or picking up a stock t56, both will be around the same price.

Cough auto swap cough

not happenin

I'd have the t45 built. Lighter, better ratios and takes less power to turn.

even with a blower? ive heard people say that the t56 is better for boost

grab the t56 you speak of and the corresponding ls motor!

If you plan to race go auto if not built t45.

quit reading the internet... ironic i know...

you'll twist the input shaft off the T56 and a T45 at the same time, both are crappy 10-spline. I think promotion still offers a proshifted T45 for less than 2k...

Where's this cheap t56? I may be interested in it

In my garage. LOL.

Yea they have a built t45 that is rated for 700hp for $1600

If you were road racing, I'd say go with the t56. They have a much taller first gear making all the rest of the gears closer together. That same tall first gear will kill you trying to take off at the track though, making you have to run something like a 4.33 gear to make it the same as it was before. Talk to Walt at Promotion, he can guide you the way. At least I think he still works there, lol.

Wait a taller first gear makes all the gears closer together? I think you mean less split between 1-2 nothing else.

What's the power level, cars primary use and budget are all you need to ask yourself.

Budget isn't an issue, I want whatever is gonna be best for my application. After the blower and meth injection 600+ hp.

Tko600

Not gonna be a drag car but I will take it down the track every now and then

Im trying to talk Ian into selling me his out of his fox.

stock ls motor and nitrous will get you that.


:hysterical:

I am just razzing you justin.

Ahh to be 20 and wealthy lol. I've never in my life been able to say budget isn't an issue with anything.

Lenko

is this a single cam mod motor?

must be a big blower if so.

yes single cam, but from my understanding, he picked up a good shortblock a few weeks ago. 600 is no problem for 2v cars with boost.

Yes I meant less split between the gears. And depending on ratios its not just the 1-2 split thats closer, all are closer. 2.66 first gear like in an fbody everything is closer, 2.97 first like the old Cobra R its really just 1-2 thats closer.

my 2v was at 13psi, and still a turd. most stock bottom end cars are under 450 and run 12s, built bottom and you can get 600whp but its not as easy as building the bottom and turning up the boost. not like i need to tell you, i'm sure you did your research before ditching the mod motors.

i'm still confused. first gear ratio change ONLY effects the 1-2 gear split, maybe i'm misunderstanding.

Im already at 316 rwhp and have ported heads and blower cams, im sure 14 psi amd some meth will get me 600+

A 2.66 first gear gear set comes with different ratios than say a 2.97 gear set. That make sense? Jesus fucking christ youre killing me.

oh you're talking t56 gearsets. I thought you meant in general a taller first made all gear splits lower. I got ya now.

From what it sounds like... you're not going to listen to anyone but heres some trans ratios for you to look at... MMR offers a "900" upgrade for the TKO600 but if you're making that much power you dont need a manual in my opinion...

T-45 3.37 1.99 1.33 1.00 .67
TKO500 3.27 1.97 1.34 1.00 .68
TKO600 2.87 1.89 1.28 1.00 .82/.64
Cobra T-56 2.66 1.78 1.30 1.00 .73 .63
T-56 Mag1 2.66 1.78 1.30 1.00 .80 .64
T-56 Mag2 2.97 2.10 1.46 1.00 .74 .50

If you do a T-56 you'd be dumb to not get something with a 2.97 first gear

Right it was just misunderstanding that all the talk was specific to t56s where first gear determines the gearset unlike others which could have the same 2-5 but optional 1st gear in which case the taller 1st gear would only effect the 1-2 split nothing else.

LMFAO @ Gears are taller in TX.

thanks for all the info guys, so i think with all that in mind im gonna go with either the built t45 or a tko600.
