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?

 

you're using an RA flywheel on a 4G63 bottom end?

 

i would most likely be using the evo flywheel, im just pretty much useless when it comes to clutches lol

 

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.

 

I'm not certain that it's easier, cheaper maybe, just less than worthwhile given the nature of the 2 bottom ends.
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...

 

Then with this information do we know if the 69 flywheel bolts to a 63 block? Has anyone compared the flywheels?

 

they're both a 7-bolt crankshaft, should bolt right up...though i can't speak of spacing for certain, but it should be the same as a 69

 

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.

 

would be interesting to see a solid running 4g63 in a ralliart. Im sorry to hear about your car man. That sucks bad. If you get a 4g63 running solid in the ralliart we should go to the track and race sometime.

 

My feelings exactly. My car is going up for sale end of this week.

 

Such a sad sight seeing your RA sitting there and then me going in and ripping away her intake.

Hopefully she's back sooner than later!
