AWDxBOOST Posted November 16, 2006 Share Posted November 16, 2006 indeed it could and it may cost a lot too Link to comment Share on other sites More sharing options...
ShockerGT Posted November 16, 2006 Share Posted November 16, 2006 From our friends at Nabisco even though it deals with a WRX What's involved with swapping from a 5MT to a 6MT? You will need to obtain and install the following components: 1. A complete 6MT transmission. 2. 6MT transmission mount. 3. 6MT clutch fork. 4. 6MT shift knob, 6MT shifter linkage, and 6MT shift boot. 5. The drive shaft from a 6MT or the drive shaft from any model automatic transmission equipped Subaru. The stock WRX 5MT drive shaft may also be modified (will need to be shortened) to fit as well. 6. New rear end options: a. New ring and pinion gears to upgrade the stock WRX R160 rear differential to 3.90. b. Convert the 6MT center differential from 1.0:1 to 1.1:1 and use the stock WRX R160 rear differential. c. Swap out the stock WRX R160 rear differential to a stock STi R180 rear differential. The real decision to a 6MT swap is the rear differential, as going with the R180, though the "better" choice, raises the costs significantly as you need to use the entire rear end consisting of the STi driveshaft, STi rear half shafts, Sti rear hubs, and STi rear discs to include the Brembo brakes. This will also require the use of 17" wheels as well to accomidate the bigger brakes, which for some, may be an additional expense. As well, www.gearboxtech.com sells the parts that let you use R180 inner CV joints and the R160 outer CV joints if you want to use the R180 rear end and not swap over to the R180 hubs/brakes.

sleepin gt Posted November 16, 2006 Share Posted November 16, 2006 its the axels i wonder about... and does anyone know what rear diff is in that 6 speed? that would answer a lot r160? r180? Link to comment Share on other sites More sharing options...
AWD_Rules3830 Posted November 16, 2006 Share Posted November 16, 2006 sounds like it would be cheaper to sell you 05 and buy a new Spec B. I love my car ... basically. Link to comment Share on other sites More sharing options...
Ed_T Posted November 16, 2006 Share Posted November 16, 2006 or have a competition rebuild on the o5 with comp clutch Link to comment Share on other sites More sharing options...
edmundu Posted November 16, 2006 Share Posted November 16, 2006 or have a competition rebuild on the o5 with comp clutch Yeah, but some of us could greatly use the additional gearing, which would allow higher top speeds than the current 5mt's limit of 174mph...

2005garnetGT Posted November 16, 2006 Share Posted November 16, 2006 5EAT swap, we are geared to go 190 or somesuch. (or just raise your limiter...) Link to comment Share on other sites More sharing options...
Guest Posted November 16, 2006 Share Posted November 16, 2006 How viable would be doing AT to 6MT swap in a LGT wagon...? AT to MT, means different ECU (or can it be reprogrammed?), clutch hardware, etc, etc... Wonder what would be the ballpark $$$... finding a used SpecB tranny won't be easy....

bosco Posted November 16, 2006 Share Posted November 16, 2006 Yeah, but some of us could greatly use the additional gearing, which would allow higher top speeds than the current 5mt's limit of 174mph... where do you get the 174 mph limit from? just b/c a car's redline and gearing mathematically will figure out to be 174 mph doesn't mean it will go that fast. there is aerodynamic losses, fiction losses, etc. which limit top speed. also if the Subaru 6th gear is overdriven it might slower than if left in 5th ie. a C5/6 Corvette will not reach top speed in 6th, too much gear. bosco Stay Stock Stay Happy Link to comment Share on other sites More sharing options...

bosco Posted November 16, 2006 Share Posted November 16, 2006 bosco, edmundu has a private track here in NJ.... these were not calculations i follow the ECTA (East Coast Timing Ass.) and he would probably have a record holder at those speeds. btw not saying it's not possible just saying using the factory speedo for a top speed run casts doubt on true mph. bosco Stay Stock Stay Happy Link to comment Share on other sites More sharing options...

Anyone thinks it's crazy? Of course the idea is to convert a 2006/2007 LGT wagon to 6MT : Link to comment Share on other sites More sharing options...
bosco Posted November 16, 2006 Share Posted November 16, 2006 Dunno how he measured it, but I'd guess a portable GPS can give one accurate speed... thats fine. just to let you know the F/PS record is 174.757, F/BGT is 164.835. F is for 2.1 to 3.0 liter, PS is production car supercharged, BGT is blown grand touring. if you are going to do top end runs at least check them out. be safe. bosco Stay Stock Stay Happy Link to comment Share on other sites More sharing options...
Vimy101 Posted November 16, 2006 Share Posted November 16, 2006 The speedo is calibrated for median speed. Get into anything above 110 and the speedo will begin to indicate progressively faster than actual. Link to comment Share on other sites More sharing options...
AWD_Rules3830 Posted November 16, 2006 Share Posted November 16, 2006 The speedo is calibrated for median speed. Get into anything above 110 and the speedo will begin to indicate progressively faster than actual. so it says 138 (not that i have gone that fast ... ) im really going like, 135?

BTW that is on the conservative side, as I have 225/45/17's, which are just a shade taller, effectively giving me about 1% more gearing. I didn't factor that in, so I could possibly wind up at 175.xx mph. My car has already bumped hard against my old rev limiter setting of 7100 rpm's. That also was on the sr40 turbo, which is a fair amount weaker than my current AVO450. This turbo pulls hard up til 7300 rpm's. I have no doubts that this combo can eat the other one up on the topend! Now, those ECTA speeds are achieved within 1 mile, right? I needed a little more than that to attain the 171mph I already did. For a standing start mile, I feel about 160mph is all it is likely to have... Link to comment Share on other sites More sharing options...
edmundu Posted November 16, 2006 Share Posted November 16, 2006 Dunno how he measured it, but I'd guess a portable GPS can give one accurate speed... I used datalogged rpm's. If they are accurate enough for the ecu to make decisions, than it good enough for speed calculations. Also, our cars employ the abs/wheel speed sensor's, for speed input, and to my knowledge it is a straight number, not fudged, that is sent to the electronic speedo. The datalogs also measure vehicle speed from the same sensors, and they actually jive very, very closely to actual rpm's. Link to comment Share on other sites More sharing options...

Yep, those are the important questions. I don't know if anyone's looked closely into the new spec-bs to answer them though. Link to comment Share on other sites More sharing options...
Vimy101 Posted November 16, 2006 Share Posted November 16, 2006 so it says 138 (not that i have gone that fast ... ) im really going like, 135? More like 130. Link to comment Share on other sites More sharing options...
bosco Posted November 16, 2006 Share Posted November 16, 2006 edmundu, how many seconds/minutes does it take from a standing start to reach that speed or do you do it from a xx mph roll? i guess what i'm asking is you go say 60mph then floor it until topspeed, again how long does this take? curious about how long car is at full thottle. bosco Stay Stock Stay Happy Link to comment Share on other sites More sharing options...
