I want to ask a curiosity question here.

Why use a WRX transmission?

Why not use a Boxster/Cayman G86-21 transmission?

My engine is the FWD version as it's more plentiful and much cheaper. The RWD 350z/G35/etc tend to get thrashed. FWD has the starter on the trans, no provision on the engine side.

Box6 disadvantages:
making a starter fit
175 lbs
short gearing
have to buy or make flywheel
small dia bellhousing
Not going to cost $100

Suby advantages:
bolt on starter
100 lbs
plenty of conversions to work from
decent gearing
coupler & axles & plate $300-500
Here is the kicker... Suby flywheel bolts on with a spacer which allows me to use all stock parts.
I can make the adapter.
Only cost $100 (IMG:style_emoticons/default/piratenanner.gif)

It's really a no brainer on my end.

To @clayperrine Clay's question: Chris is handy and clearly likes to fab stuff so more of a DIY may appeal to him. Plus the aforementioned cost savings.
Plus, I suspect Chris is a charter member of the "mine is different/special" club! (IMG:style_emoticons/default/aktion035.gif)

That said, I've been noodling on re-powering my LS car with a Nissan V6 and, if I understand it correctly, Kennedy Engineering could supply a complete adaptor kit to the Boxster trans, if he wanted to go that way.

I think this is more your forte (IMG:style_emoticons/default/biggrin.gif) @tygaboy

The starter is not a big deal to remedy, but I can't beat a 6 speed trans for $100.00.

Post picts. I want to see this setup.
