Default difference b/t the STi and the RA

sorry if this seems like a lazy way to get info, but i don't know what to search for (the title seems like i'd get a lot of garbage along with some info)

so if it can be explained easily or someone could point me in the right direction to get this info it would be great (mostly to satisfy some curiosity and also because i want to swap one of those setups into a 2000 RS at some point)


thanks in advance!

Well there are few diff RA models and STI depends on version STI and what model RA. There was a WRX RA version and a WRX STI RA. Have to be more specific and what details you want and I will be glad to help. Also, diff years have diff trany and so on and features!

Well, the Ver. 6 STi will be 276hp, 8K RPM redline, sodium filled valves, etc. The Ver. 7 STi will have the addition of the AVCS valvetrain. The Ver. 5 RA will be very similar to the Ver. 6, but will have the adjustable center diff and hardened gears.

Those are the most significant differences, I'm sure there are others, though.

thanks!

there are more versions of impreza's than i thought

so basically the RA's are more durable? or designed to withstand more abuse/power? (not that i would abuse my car, but abuse in the sense of being pushed on a track or what not)

so which would be better (say in the hypothetical MY00 RS) the V.7 or a V.5RA? (not looking to tune it further than the base engine output really (~280hp)) but i will be changing the suspension/brakes/drivetrain[associated w/ the engine] and other non "go" aspects of the car... or would the difference in performance be negligable..?

thanks again for all your help!

ver 5, 6 would be better for a whole swap as suspension and swaybars and xmembers and all that jazz are made for the gc8. For engines i'd go with the ver7 as they have avcs and more torque. I was also under the impression that v5,6 sti's had dccd standard, and wasn't RA specific. Could be wrong though.
Type RA's are lighter from the factory. Type RA's were 4door until ver5 where you could get a Type R two door. Type RA's in ver 7 are only 4door. Some ver6's had avcs supposedly and there are two types of heads on the ver7's. From the type RA's from different. years they had roof scoop, special 555 blue seats and other cool things. My dream car would be a STI ver 6 Type RA. I've also heard they are the fastest impreza, yes even fastAr than the 22b. There were also v-limited impreza's STi and non. Not to mention all the Genome options you could get. Lots of cooky crazy combo's that probably only subaru really knows how to sort out.
Not to mention all the differences in engines from year to year, phase 1,2, open deck, closed deck, semi, sodium filled valves, redlines, power outputs, turbos, etc. It never ends
I know that was a very unstructured answer but this stuff makes it hard to think, lol. Hope that was helpful.

the regular STi's had more power out of the box than the STi RA's because the RA's didn't come with the more powerful cams and forged pistons because Subaru figured that people would be replacing them with competition parts. Hints the nam Race Application. So for best bang out of the box the STi is the way to go for an engine.

I'll try to remember where I read this but it said that the cams and pistons were different and lees performance oriented because they where expected to be replaced with racing ones such as Arias and JE ones. I'll try to find it but don't know if there was any relevance to this.

yeah man, i have a motor from a 1997 WRX STi Type RA. (what version would that be?). that car had the close ratio 5 speed with DCCD, forged pistons, sodium filled valves, and a redline of 8250. And ill bet you if you put the engine on a dyno youde see more like 320HP at the flywheel. even though its rated at something like 280. Oh... and im pretty sure that this particular engine has a hotter cam than most of the others as well....

The 1997 is a Version 3.

Homemade WRX is talking about the WRX RA, not the WRX STI RA. He just doesn't know

That's a good resource for all the different types of Impreza made before the GDs.
