Future plans for the RA

stock 4G63 for an Evo 9 makes like 290hp 
even for a FWD car it won't be too much...an LSD might be in order though... but a little bit of tuning, maybe a bump in boost and you could easily and safely make 290whp which gives you a power:weight of 1:10 which would be awesome 
that's my goal.

Anyone have a quick answer for this before i start ordering parts? Curious as to the clutch, will i need to mix clutch components or will the RA clutch be fine?

From input shaft diameter and spline count the 4G63 flywheel seems incompatible with the RA gearbox.
This is based on specs I have come across on sites like rockauto and some other sites selling parts.
I have not had the privilege of touching one.

Before I got my evo and put the RA on hold, I had started to draft a head swap from a 9 to the g69 block. Seemed to me to be a lot cheaper and easier than the engine swap. Just my .02.

Where the 4G63 starts performance the 4G69 ends. You dont just want to say you've done it, you want it to be reliable and durable too.
I see compatible 4G63 engines from $2000 closer to $3000 is the norm, with wiring harness, ECU and engine accessories.
How much less would it be only getting the parts for the head swap ?

i'm with george, if you're going through all that trouble, your best bet is a full engine swap... unless you build the 4g69 block, but after rods and pistons, plus rings bearings and seals, you're probably getting close to the price of a decent mileage 63 anyways...a modestly built 4g69 won't handle much more than a stock 63...

yeah from browsing through the swap thread that was linked here the guy said he used a RA flywheel and clutch. so looks like thats the route i will take. i figure within 3-4 months ill have a motor setting in the garage awaiting install.
