GTWILLY Posted January 19, 2008 Share Posted January 19, 2008 Does anyone know what manual tranny will bolt up to a 3.0L or the new 3.5L? I am starting my build for a turbo flat 6 motor and am in the research stages right now. Link to comment Share on other sites More sharing options...

Guest Posted January 19, 2008 Share Posted January 19, 2008 Yeah, it will. Lots of SVX conversions around. Link to comment Share on other sites More sharing options...
GTWILLY Posted January 19, 2008 Author Share Posted January 19, 2008 Yeah, it will. Lots of SVX conversions around. What will? Our stock 5mt tranny? If so I would obviously not be keeping the same gears inside but need to know the case that will fit. Link to comment Share on other sites More sharing options...
Guest Posted January 19, 2008 Share Posted January 19, 2008 Any post 1990+ tranny will bolt on. Subarus are like Legos. Link to comment Share on other sites More sharing options...

GTWILLY Posted January 19, 2008 Author Share Posted January 19, 2008 Wow..subscribe! You may be subscribed for a little while as money is a key feature in this decision. However it is going to happen, I am just gathering info so I can figure it all out and start collecting parts and building. Link to comment Share on other sites More sharing options...
GTWILLY Posted January 30, 2008 Author Share Posted January 30, 2008 Anyone know if a Porche 3.6L motor has the same bolt pattern for our trannys to mate to? Link to comment Share on other sites More sharing options...
rc0032 Posted January 30, 2008 Share Posted January 30, 2008 Why not run a STI 6mt? More than strong enough and you are already dumping a lot fo $$ into this. (dont forget the new rear and 1/2 shafts) Also just how much $$ do you think this will cost? I have a number but I want to hear yours first Link to comment Share on other sites More sharing options...

I have a number but I want to hear yours first I have been told that any suby tranny will bolt to any suby motor after 199something, and I figured I would run a 5mt so I would get longer gears. PPG upgraded of coarse. I wanted to figure out if the Porche block is the same pattern to bolt up to a suby tranny. As to how much it will all cost... I will be doing all of the work, but parts along and tuning I figure will probably be between $15-$20k. $5K for tranny upgrade $1K for clutch $1200 for EMS $5k for short block build $5k for head build $1k for a custom tune $2k-$3k for whatever I am missing Link to comment Share on other sites More sharing options...
rc0032 Posted January 30, 2008 Share Posted January 30, 2008 you are about 50% too low IMO What about a turbos? that alone will run 4k and a ton of custom fab work. I said it in the other post but V8 swap is the best way. Link to comment Share on other sites More sharing options...
GTWILLY Posted January 30, 2008 Author Share Posted January 30, 2008 Its fun having this conversation in two seperate threads. I know it is going to take a lot and I am just looking for a project that will occupy my life for a few years. Some guys like building a hot rod. I like working on Suby's. I may end up with a strocked H4, who knows. I havn't even bought a block yet, but thats why I am doing this research. Honestly I didn't think about how much of the piping would have to be custom fabbed. So you got me on that one. The turbo will be picked when the motor is built. So I have no idea what one will go on yet. Link to comment Share on other sites More sharing options...
Guest Posted January 31, 2008 Share Posted January 31, 2008 Anyone know if a Porche 3.6L motor has the same bolt pattern for our trannys to mate to? My guess is they have completely different set of lego blocks. Link to comment Share on other sites More sharing options...
rc0032 Posted January 31, 2008 Share Posted January 31, 2008 Honestly I didn't think about how much of the piping would have to be custom fabbed. For a H6? All exhausts parts custom, intake custom,Manifold custom, mounts custom, FMIC custom. Perrin did it for a STi. and put 40k into it.

ultimakf7 Posted January 31, 2008 Share Posted January 31, 2008 Anyone know if a Porche 3.6L motor has the same bolt pattern for our trannys to mate to? Bolt pattern, possibly... but not likely. Placement however is a totally different story.. aren't the engines placed in the rear of the car? So a subie tranny definately won't fit right with a porsche engine (with a mid/rear placement engine). A mid-engined subie would be pretty damned interesting.. but you'd probably custom fab a helluva lot more stuff... Link to comment Share on other sites More sharing options...

I know they are mid engine cars but I didn't think that made the engine only mountable in the rear. It was just a thought for a case that might be stronger.

BigT Posted January 31, 2008 Share Posted January 31, 2008 Just a side note on the 3.5L I believe that they had to increase bore and stroke on the 3.0L to get there, and from what I've heard that didn't leave much room. From previous discussions (can't remember what thread) I believe that there was a concern about the strength of the block/internals if they were to be put under any kind of boost situation. (hope that made sense) Link to comment Share on other sites More sharing options...

BigT Posted January 31, 2008 Share Posted January 31, 2008 Wouldn't sleeving the cylinders help in that situation? I'm definetely not an expert, but my understanding is that sleeving would only help in replacement situations, or slightly stronger initial design. The problem with the new 3.5L is that the block has sacrificed strength in order to gain larger displacement. Sleeving would make the area in the block stronger, but it won't change the fact that the block has been weakened because it has lost some of the area that it had for strength and given it to displacement. I'm an engine noob, so if someone can say this better, or can correct some mistake I've made, please do! Link to comment Share on other sites More sharing options...

rao Posted January 31, 2008 Share Posted January 31, 2008 The issue with the new +3 displacement H6 is the offset connecting rods. Sleeving it won't help. Have fun Rob IF YOU CARE ABOUT YOUR CAR YOU SHOULD NEVER DRIVE IT Link to comment Share on other sites More sharing options...
