I'm not planning on doing a manual swap, if I were to do that I would get a much nicer and lower mileage car before doing anything crazy like that. Plus I like autos. I'm not planning on making this think an all out race car or anything. I already have my GTP for that, which is still full interior etc too. I think I've set my mind on either an 18T or K24. How much can I get a K24 for? My Volvo goes about 80 in second gear, idk if its just because I'm running a 205/55-16 as opposed to a 50 sidewall they originally came with. But yea, let me know if there's any good deals on turbos lol.

$500ish for a used K24 on the forums seems to be the going rate. I sold my fresh rebuilt K24 for $600. Make a wanted add, and see what comes your way.

So what you're saying is, even if you trap 120, an auto shifts 3 times and a manual shifts 4 times? It's been beat to death. There are pro's and con's. And if you're interested, the number estimations you posted are documented somewhere around here, sourced from VADIS.

Its this combined with a little extra whp you get from the auto to manual swap that makes it worth it when your running a good amount of power. Its not a god like transformation. But you do reach a point where a manual swap is necesary (over 350whp)

Like you said, pros and cons, no need to do it on a daily driver.

[-Matt01]

either way, i didnt say it would add 100 horsepower, its just a good mod considering if you can lanch it properly you can probably achieve a better 1/4 mile time.

Same goes for dyno, surely you'd be able to put the power down better with a manual tranny.
Don't fully understand what people disagree with.

Kinda got me convinced to run some e85 next time i go drag racing. Which should be tomorrow but I couldn't get the day off work, so maybe next month.

Yea, I was thinking about making a thread but I'm not 100% sure I want to spend the $500 on that at the moment. I'm thinking of just going with some Green Injectors and running 100% E85 on my current setup then ill have the fuel for the bigger turbo in the long run since the whites are maxxed at the moment, and ill need them anyway.

Well my trans blew up a couple nights ago, I was slowing down and it didn't feel right, then when I got on the throttle it was stuck in 2nd gear then when back to first once I got moving, slowed down again, then when 1st through 3rd up to about 30ish mph then it shifted back to 2nd automatically then proceeded to rev higher and higher in second but also lose speed, came to a stop and had no gears. turned it off for about 2 mins and was able to move it about 30 ft, turned it off for 10 mins or so and was able to make it up to about 40mph before it lost the trans, moved it couple times like this and gave up on it, and had it towed home. Now I'm really not sure what to do, might just wanna buy another 850 or something.

Make sure you get a tranny cooler for your Auto box if you plan on adding power or running it hard (no pun intended). It will save you from a forced manual swap

Yep, the only option i see is getting a new one put in, or a manny swap.....

Or get the GTP running.

Yea, I've been trying to decide between auto and manual lol, manual would be cool just because my GTP is already auto and it would be a fun variety of cars. The GTP is running at the moment, it has just been in and out of the trans shop. The trans is working for the most part now, just need to take it in tomorrow to have it checked out for an odd slip issue from a stop, almost seems like the fluid is too thin? we'll see what it is. But yea at least the GTP is done for the most part. I am able to drive it. As for the Volvo I have to decide how I'm gonna fix it, and also how much I'm willing to pay lol.

You've been racing that 850T HARD for over ONE YEAR now(as per your youtube videos), done 10s of power launches(brake tourqing) since you got it? What'd you expect?

Don't toss it to the side, do an M56 swap and keep enjoying it! If not, i'll come over and pick it up for my affiliate...

Thats why i suggested him to do a M56 swap, i just didnt wanna be so "obvious" on the reason why the swap would benefit him.'

Thats how my tranny died., Im pretty sure you saw one of my mexico runs.

[vmaxx]

ha yeah the one George Foreman was apart of.. or was that after you did teh swap?

[Jardim]

hahaha yeah that was before the swap, oh man that night was hilarious.

Well its expected, just weird it died randomly with no signs or anything. I'm pretty sure if done hundreds of launches probably in the 300-400 range. But I was planning on doing a manual swap since its not much more than another auto and would be fun. But, I just found out that I need to make room for another car so I either have to get rid of one of my cars or move to my own place.. Seems that selling one is going to be the best thing to do, I really hate to see either one go, but I have to do something. I wish the GTP trans would just work 100% then it wouldn't be such a hard decision. I'm really stuck as to what I should do. I font really have much I can part out on the Volvo to make any money either.

[vmaxx]

Sorry to hear, one thing's for sure, the Volvo stays.

[Jardim]

The question is, which one is going to be a good cross between drivebility on the streets and provide you the most fun?

[850wagonT5]

I know you from your YouTube vids as well.

Don't let the blown trans get you down. It's a cheap junkyard part. Just spend the extra coin on GOOD FLUID and a COOLER. Mine has lasted for who knows how many miles. My auto trans was in a modded 15G car prior to mine with a lot of miles on the ODO. Now, it's seeing near 300+whp and 300+wtq, and it's been that way for a year now. Still seems to be doing OK, though lately, some of the shifts have felt a little funny, so I might be pushing my luck by typing this. lol.

I think the trick is that I don't beat on it from a standing start hardly ever, and I've only brake boosted maybe half a dozen times since I've owned the car. If I do romp on it, it's usually from 65+ on up. I'm running the stock radiator cooler for the trans, though I've rerouted the oil cooler which (theoretically) lowers the thermal load on the radiator and allows more cooling to the trans. It's about to go under the knife, though, and it will get dedicated cooling as soon as I can afford it!

Yes, there are minor power gains. But the idea of swapping in a 5speed as a power gain is ridiculous.

Think of gears on a bicycle. You have a given amount of effort being applied to the pedals (or to the wheels). Distributing that power through 5 gears instead of 4 means more of that power reaching the ground. Each of the 4 gears in the auto are slightly taller, therefore requiring the engine to work harder, for the same given speed, when compared to the shorter gears in the manual.

The reciprocating mass is also lighter being that there isn't a gigantic torque converter and many more liters of trans fluid inside of it sloshing around as it spins up and spins down. That also allows more engine power to reach the wheels.

There's a reason that the manual versions of almost every production car ever made usually publish not only quicker acceleration, but often more advertised HP than the exact same car in the auto version. It's negligible, but the manual variant also typically includes 40-80 lbs of weight reduction.

But this is easily verified looking at 8/70s with the same mods in roughly the same conditions on the dyno. The manuals put the autos to shame given equal conditions.

That all being said...I love my slushbox. I see no reason to switch to a manual trans. When this box blows, I'll be putting another auto in.

[Jardim]

I loved the swap, definetly a nice addition to the car in the peformance department. But if my auto hadn't blow i would still have it.

There is so much wrong with this post, I don't even know where to start.

[volvos70turbo99]

honestly I don't see a lot of manual cars with more advertised hp than their auto counterparts, even if the auto is 4 speed and manual is 5 speed, only one i can think of off the top of my head is the rx8 which is a 6 speed in both versions, 20hp difference. The only reason I think why manuals post quicker acceleration speeds is because they can launch it at a certain rpm, i mean auto you can I guess but it wouldn't really have the same effect, right? I like my auto, screw it.
