Asking members who have ran either transmissions or BOTH (preferably) on their 1st gen is300:
Anyone on here running a cd009 6-speed trans? Did you end up swapping out the rear end as well? Absolutely torn between getting a brand new r154 through driftmotion (the newer tripod version with triple synchros) or going with the collins kit cd009 swap for the LONGEST time. I've done research on both for the 2 past years but trying to find someone who has ran both transmissions / or even one or the other and can provide insight on their experiences.
Plan is to eventually push 500-600hp with my borg warner s360 big single as I know our auto rear diff (3.91) is perfect with the r154 but just hesitant with how notchy it is even with a cube speed short shifter. If I'm spending around 6k for the swap I just feel like I should be getting a buttery transmission. If I were to go cd009, I'd definitely get the serial 9 cd999 shifter as well. I know t56 is the best 6-speed option out there for us but 8k for that swap is just out of my budget.
Here's are reasons I'm still torn:
R154 5-speed transmission -
Pros:
-good/reliable to around 550hp w stock internals
-easy manual swap
-perfect for the auto rear end (3.91)
-tall gears / good for single turbo
Cons:
-"truck-like" trans feel / not buttery
-shifts aren't what you'd expect in the "modern era" of double and triple-cone synchros
-parts to replace down the road are more expensive and continue to go up
-30-40 year old trans model
cd009 6-speed transmission -
Pros:
-6speed gear ratios almost identical to v160
-good for 800hp+
-strong / stout transmission that's extremely affordable
-parts to replace are cheap
-collins has a full kit readily available
-2006 final revision model
Cons:
-short gears with the stock auto differential
-would have to swap out the rear end - gs400 or TT?
-harder manual swap (requires hammering the tunnel for clearance, need to run spacers to adjust height from cross member, potential cutting around shifter area)
Any insight would be much appreciated!
