Chad Posted November 15, 2004 Author Report Share Posted November 15, 2004 we need more interest to get this off the ground. I need to emphasize that you do NOT have to drop $2000+ now, concider the the benifit of buying the $600 kit now, and getting the transmission, driveline, and clutch later. Think of it as an investment in your cars future. See is as a 2-3 step process, much like a MPI conversion is. The supply of 88-89 transmissions wont last for ever and neither will the parts. With people starting to make the numbers they are now, and the seeming limit of 425 TQ which is getting easier and easier to get, people should make plans for one those two reasons to convert. A good friend of mine just spent nealry $1000 on a "race built" 88/89 with cryo treated gears and all, It was rated at 650 HP and 1 year warranty, it lasted 2 months with only ~325 HP and ~410 TQ at the wheels. The T56 is rated for more than that from the factory, and designed for a heavier car too. It can easily be upgraded tremendously, and repaired cheaply. Plus the T56's parts availability, there are 10x's as many T56's and lots of parts makers, aftermarket and OEM. 10 years from now this will still be ture. Where will you buy tans parts for your stock 5 spd. 10 years from now?

Shelby Posted November 15, 2004 Report Share Posted November 15, 2004 wonder where we'l be in 3 more yr's Chad,, 3 yr's ago you'd have been hard press'd to find any one that need'd that tranns ,, now we have at least 10 guys that can use one now ;D it'l take at least that long for all the advances we've made to come togather and click as the should Link to comment Share on other sites More sharing options...
alex_romo Posted December 6, 2004 Report Share Posted December 6, 2004 in my opintion, it would be easier to get a T5 kit i have a freshly rebiult and modded T5 sitting in my mustang right now, and doesnt look like its going anywhere, is there a way i can adapt that tranny to my car?

smog Posted December 9, 2004 Report Share Posted December 9, 2004 t56 is a hell of a lot beefier than a t5. might be easier for you, but I dont want it. Link to comment Share on other sites More sharing options...
TainterRacing Posted December 9, 2004 Report Share Posted December 9, 2004 I like the Idea but after lookingh at the Gears the t56 has I dont think it would work out all that well..... but It is nice to see some one doing what you are chad and I hope it works out for you.

Chad Posted December 9, 2004 Author Report Share Posted December 9, 2004 look at the ratios if you swap in the 4.22 gear set, the final ratio is almost identical to stock, and has the 6th gear to grab. I posted these ratios in the 2nd post in the GP forum. Link to comment Share on other sites More sharing options...
TainterRacing Posted December 9, 2004 Report Share Posted December 9, 2004 That is true But in 1st gear you have to have a set of 4.64 in there to be the same as a car with the 3.90's I think it would work very good for guys that are not super big in to drag racing very good for a street car I will say that 6th would be nice for the longer drives for sure. it is not bad at all Just not the way i want to go with my car. That biger Clutch is a very very good Idea!!!! Link to comment Share on other sites More sharing options...
smog Posted December 13, 2004 Report Share Posted December 13, 2004 I'm sure you could find just about any gear ratios you wanted with a t56. Link to comment Share on other sites More sharing options...

Chad Posted December 13, 2004 Author Report Share Posted December 13, 2004 http://www.g-forcetransmissions.com/tran_gt-56.asp#ratio look at the bottom of the page, 3 different main sets, and 3 different OD sets as well (9 combos). There may be others with diferent vendors, I haven't checked... Link to comment Share on other sites More sharing options...
Grey_Wulf Posted December 13, 2004 Report Share Posted December 13, 2004 I've seen a TREMEC parts list with a gear set starting with 3.36 . That would be really nice. I'm hoping that i can find something more like that that'll have a high rating. Link to comment Share on other sites More sharing options...
TainterRacing Posted December 13, 2004 Report Share Posted December 13, 2004 mm thos would work out well get the steepest ones you can and a set of 4.64 would be sweet for the car I bet. I all most wish I did not have the 700r4 but I would like to at lest see how well that works out Link to comment Share on other sites More sharing options...
columbusquest Posted January 14, 2005 Report Share Posted January 14, 2005 So... You're saying that it's possible to swap the gear ratio in the trans in addition to the rear-end? That would be nice! I'm, for sure, interested as I have an 88 trans and the sync's are warn and need replaced. I was thinking of just purchaing the rebuild kit (about $250) but I'm interested in a beafer trans since I'm going to be making some serious HP before the end of the summer. (going mapi with T3/T4, Haltec E11. and nitro) I'd like to have a nice drag car with the 4:22 rear with 6th gear doing about 3k RPM at 65MPH Is it possible?

vengeance484 Posted March 11, 2005 Report Share Posted March 11, 2005 i'm definitely in on this...but, i won't be able to afford it until i'm outta school and makin some decent money this winter. Link to comment Share on other sites More sharing options...
shift1313 Posted March 11, 2005 Report Share Posted March 11, 2005 what about the torque tube? how does the t56 fit in the tranny tunnel. I dont really like how tight it is in your pics. especially the "after hammering out". With yours it looks like you have to use solid motor and tranny mounts cause if that thing torques your in trouble. correct me if im wrong.

Chad Posted March 11, 2005 Author Report Share Posted March 11, 2005 The rear trans mount on the T56 is compact and it has very little flex. Even if you had broken motor mounts, the trans probably won't hit anything. the tightest portion of the trans tunnel is arround the rear 1/3 of the trans where deflection is the least. What about the torque tube? it will use the stock one. FYI, there are several 9 second full body quests that run a stock torque tube, no problems there.

shift1313 Posted March 15, 2005 Report Share Posted March 15, 2005 You said your making/ having made a 7075 series aluminum pinion flange so we can use spicer 1350's that will hold 1000hp, how much will the adapter hold up to? is the flange going to be treated at all? I know it is able to be heat treated and must be annealed before machining. shear strength is 30ksi for tempered t6 6061 , 12ksi un-tempered and for 7075 is 22ksi and T6 is 48ksi. a 6" solid slug of 6061 t6 is about $150 and the same for 7075 is about $450. whats the construction of the pinion flange(pics) have you greatly increased the size of it. what about the adapter plate for the flywheel and the bell housing adapter. If you have this thing bolted up to your car, no doubt you have the parts to show. Link to comment Share on other sites More sharing options...
Chad Posted March 15, 2005 Author Report Share Posted March 15, 2005 "I know it is able to be heat treated and must be annealed before machining." What is your source for this info? I have not anealed it, machines beautifuly at a T-651. It's yield strength is 66,000, 20% higher than 1018 low carbon mild steel. This stuff is stronger than most steels !! a 6" solid slug of 6061 t6 is about $150 and the same for 7075 is about $450. Sounds like you need some advice on how to shop I've gotten a 6' long 4" OD piece of 7075 for this project for $650, enough for 26 pinion adapters. "If you have this thing bolted up to your car, no doubt you have the parts to show. " I'm not posting pics untill I am 100% commited to a specific design, I've made 6 prototypes to make sure I maintain max strength while giving propper clearances. "what about the adapter plate for the flywheel and the bell housing adapter." What about them? I'm not sure what you are asking. I'm using 6061 T6 on both, the adapter is 3/8" thick. whats the construction of the pinion flange(pics) have you greatly increased the size of it. It will look a lot like this: http://www.iedls.com/jpg/Almn_yoke.jpg With the exception that the back will be a flat flange to mate to the stock torqu tube input flange, not the splined shaft you see. Basicaly I've taken a proven design and a proven material and adapted it for use in the starquest. If you doubt it will hold up, you may need to ask some guys who have this Inland Empire billet yoke in their 1000+ HP hotrods. Link to comment Share on other sites More sharing options...
shift1313 Posted March 15, 2005 Report Share Posted March 15, 2005 the 6" piece was just a price reference from the two from onlinemetals. I dont buy from them because of their high price but it was a good example of price difference. I wouldnt use 1018 for that flange either. Everything i have read anywhere has said you should anneal 7075 before machining. this is from metal suppliers online "It is best to machine this alloy in the annealed condition. Machining capability is good and oil lubricants should be used. " I just want to make sure you are looking at every aspect and make sure that everyone gets a superior product. I wouldnt buy a 7075 pinion flange that was splined or had bolts to hold the 1350. Thats just me. It may hold for what we put down but i dont see it holding 1000hp. Now if it was a flange that bolted and spread the load and the 1350 was pressed in. Im not sure what the best design is. What you end up with may be the best design and i dont want to critisize that i just want to be sure you have the answers. I will just sit tight until you are done with the designs and ask my questions then. Link to comment Share on other sites More sharing options...
