Q45 High Stall Converter Question

[Jeff Williams]

I am in the process of beefing up my transmission in Lola, and need to get a high stall converter. I am looking for the easiest and cheapest route.

Has anybody tried the 300ZX twin turbo converter in the Q45?

The bolt diameter is the same, the splines are the same, and the bolt thread count and bolt size is the same. The difference is in the main body. It is a smaller and lighter TC, so the stall speed should be higher. I really don't know much about TC's, but this seems to be the easiest route to a higher stall speed.

What I need to know is the height or depth of the TC is the same?

The part number for the Q45 is DA-30 from Dacco and the part number for the 300ZXtt is DA-31. They are regular catalog items and there is one in stock in Huntsville. Rather than ordering both, I was hoping to find out here.

My other option is a Dragon billet TC from Precision Industries. This is an expensive option.

Any help would be appreciated.

I'm back to a stock TC on Da Beast, so I'm interested in what you find. Keep us posted.

I would personally get a billet TC. The rebuilt high stalls probably wont have you satisfied, because then it becomes the really weak link in the transmission. My L10 trans is solid, but the TC is on its last legs.

go big or go home. The twin turbo TC's wont work, they bottom out on the input shaft of the trans.

get the precision tc - $ 750 i love mine - make sure u send them ur stock one for reference. 2800 stall is nice - if i did it again would go with 3000 or 3200 -

So, they are not tall enough? It is not a problem with the flywheel attachment, it is aproblem with the input shaft to the transmission. That makes it hard to modify.

Does anybody have specs on teh twin turbo transmissoin?

I REALLY don't want to spend the extra $750 on the billet one. But if that is my only choice, then I will go with that.

I didn't get a spare when I got the '93 transmission from the pull a part. We ran out of time when we were scavenging, and had to leave the TC. I think the donor car has been scrapped. Kinda funny, a junk yard scrapping a car, huh?

I wish Precision Industries would just order a DA-30 torque converter and then I wouldn't have to send them mine. I don't want t obe without the car that long. I guess I will try to find a donor TC somewhere.

jeff if u pay round trip shipping i could send them my stock convertor,but maybe they dont need it maybe they learned on the first 2 attempts that went wrong with mune. the prob was that they forgot having not made any in years. lmk James

If you dont want to go the billet route, send a stock converter to level 10 or IPT (the latter preferred).

not worthit arent they like $450 ???

[Jeff Williams]

I am talking with IPT about it now. I will see what they can do for a 3000 stall converter.

I don't think I will really need the billet strength with the HP and torque of the VH engine. If I were going FI or Nitrous, sure.

[Q45tech]

If you increase the engines WOT torque by 10% [with ecu] the effect is to raise the stock TC stall rpm by 10%...............assuming the same ATF temperature/viscosity.

[Jeff Williams]

IPT wants $575.00 plus a $200 core charge for a high-stall converter.

I may jsut buy the Dragon billet one for $750.00

Is there any cheaper prices out there?

By the way, the NICO ECU dropped my WOT torque, not raised it.

what is nice about the billet from precision is you do not loose top end as u do with a mod stockk, also they will for free change ur stall 1x if u r not happy -- get the billet
