PTC th400 converter
I'm in the market for a Torque Converter for my New LQ4 build. I built this thing to handle a small kit of nitrous, and need a torque converter to handle up to a 250 shot. I'm almost sure I am going to give PTC a call. Wish their web site hadn't changed to where they don't list any prices.
My reason for this post is does ANYONE know if PTC has a budget converter that can handle a 250 shot ? OR do I have to spend $1000+ ? This car doesn't get much street miles on it but I do like to drive it to the RACE spot. ( Street Racing only )Which is about 15 miles from where the car is stored. Its Basically 60% strip- 40% street. And care mostly about performance.
Any and All recommendations are appreciated!!!!!! Tim in New Orleans

Just call them. They are a quality company that makes a quality product. Don't try to shop around in a forum...just call and ask them to spec and quote you a converter. With their reputation, they are going to want to sell you the best product for your setup.
If that means a budget converter...then that's what you will get
if that means you need a $1000 converter so that you don't blow through it on spray, or so that you don't balloon the thing and wipe out the trans pump or engine thrust bearing...then you'll get the high dollar unit.
Don't waste your time wondering what it's going to cost in some forum.;..just call them and dole out any details you have...and they'll get you properly setup.
Because believe me...if you try to skimp by and get a budget converter...and have issues...then end up still having to buy the expensive unit...it is going to cost you not only more money...but it's going to be an assache and a waste of time also.

When I went Th400, I used PTC and have absolutely no regrets. It was by no means a budget unit, at least by my standards (little over $1,000). But It really pays to go ahead and spend the bread up front, instead of doing it twice. And yes, a cheap converter can make a mess of your motor in no time.

Thanks Guys but its easier "Said than Done" to just buy what ever they suggest. I don't think I need a $1000+ converter. And I hate pulling a transmission in the driveway. So I would like to get this right in the first ( or second ) try. I have used PTC before and was totally happy. Remember I am new to real horsepower and I couldn't believe I could go 10's and have a converter that feels like my daily driver. I also know the value of a quality converter. Which is why I am here asking about PTC and what I can expect to spend
I guess I'll be calling them after the New Year.

I've seen not a bad word mentioned about PTC converters and especially in turbo applications. I wonder how good TSI converters are in comparison, more so their spragless converters

I have a used PTC that came out of a s10 I bought last year with only idle time on it. Was behind a 383/plate kit, with a th350 but converter should fit a th400. part number is PTC 10th SS ET 56576

Also OP, I wouldn't go cheap. If you don't spend 1k on a converter, you will just end up doing it twice as other said. A cheap converter built to handle under 800hp, won't have a better sprag in it or a ratchet diode sprag, or be spragless. Those stock type sprags can and will begin to slip and you will lose et.. regardless of if the rest of that budget converter can handle 800hp.. the sprags won't hold. Especially if you street drive it and get wheelspin often and then hook suddenly.

A converter is not the part to be on a budget for performance. It can make or break the combo at the track. A good quality converter will be $800+ minimum. Call around and see what the converter companies recommend. Remember if you are not going to spray a 250 shot all the time you want to tell the converter company what you plan to spray most of the time. A converter setup for a 250 shot will be a dog N/A.

Yes, this is a vid of me goofing around, but for the purposes of this thread it's to give a glimpse of the low speed driveability of a good turbo converter. This is a 9.5 inch PTC that goes 5200 on the tbrake, but doesn't require 3500 rpm to get the car moving, roughly 16-1700 and it's moving at a reasonable pace around town, but under power it still couples up nicely. I understand the money angle, trust me, but after paying $200+ for main bearings and all the work involved....on top of now having to buy the converter that you needed in the first place..... see where this is going? Some people get away with cheap converters in turbo applications, but if you're luck is like mine, you won't. And here's another thing, some th400s have been known to take out brand new bottom ends on their own (too much charge pressure), so why compound the potential problem with a cheap converter that may balloon when behind a turbo mill?

I bought a budget ( non-custom) converter from PTC for my Gen 1 SBC build. But it only makes 500 flywheel hp. Although it does fine in my car now, I don't think it could handle a nitrous hit. And like I said, I hate doing transmission swaps in the driveway. So I want to get this right, or very close, the first time. I could spend 1500$ on a custom converter, but I don't think I really need that for several street passes a year. I Will get PTC a call to see what they come up with. My second pic is Jakes transmissions in TX.

I'm sure PTC will give you a recommendation about what converter to go with depending on your power level. I have one of their "budget" $450 converters and and very happy with it. I was asked a ton of questions about the car and plans and it's been a great converter so far behind my new motor.
