M20b25 turbo gearbox g260 info

Hello again all, I know this has been done plenty of times, just wondering after reading a few threads what the latest recommendations are for fitment? Pics would be great? I appreciate the trans tunnel is often necessary to open up to make matters easier

 

proposed setup is m20 turbo with g260 

 

thanks in advance

G260 won't fit without cutting and rewelding.

it is, as my teenage son says, a chonky boi.

If you search the m20 swap thread, I posted a side by side comparison between the 245 and 260.

 

New tunnel, or splice/widen the existing one.  Just try to align the transmission’s output flange with the diff input as close as reasonable.

 

Good luck on the swap!  Love the m20.

...and the 260, while notyet nowheres nearlys as rares as the 245 nowadays, is starting to 

become a bit hard to find.  Me, doing something like this, would go either

to a 6 speed out of a 3 liter  E46, or to a Muncie rock crusher out of a Cam-Ay-Row.  (or corvette)

 

Since you're in for custom sheet metal and driveshaft either way,  the 6 speed's really tough,

and the Muncie SOUNDS really tough!

Advantages to the 6 speed are an overdrive 6th, quiet, and, well, better ratios.

And more of them.  And jeeze, they're not that expensive.  Yet.

 

Actually, I might use a T5, but that would be for sentimental reasons.

A T56 would be far better.

no half- measures here.

I’ve been doing a lot more research and should have mentioned I’m across the pond with a RHD here in the UK. I have an e30 m20 turbo and a spare setup so thought it’d be ideal for the 1602 but from what I’ve researched I’m in for a lot of painful fabrication work with steering boxes and other issue for the downpipe etc. 

 

The g260 here in the uk I can get easily due to the e30 scene, contemplating an m44 turbo route just seems a shame to change plans

oooh, yeah. RHD and Turbo M20 is going to be a challenging combo.

 

@camperman had a really cool RHD M20 swap running triple IDF carbs.  Something to consider!

 

 

[TobyB]

Ah, yeah, if you have the E30 stuff, that's a good reason to do it.

 

Normally, I say a rack conversion's a bad idea, but to get room for the turbo,

it might help... I guess it's a matter of picking the battles you want to fight

as to which problems are going to be harder to solve.
