Default How do I make the 2.5 RS into a high performance street car

I drive a WRX now, but when I go to college I will be giving the car back to my dad. Unless I go to NYU, I would still like to have a car, but I still want a relativly high output of performance (mid 13s?). So I was thinking...

Maybe get a old RS with some seriously high milage and swap out the engine with a 2.0t, 2.2t or another 2.5t or get an RS with low milage and turbo it

Keep in mind this would be a long ongoing project and I would like to learn as much as possible while I'm doing it.

I want the car to be practically bulletproof and reliable. Low end torque is nice, but I love the high end punch and would be willing to sacrifice a little low end for it. Now this is what I understand now: If I want high end, I have low compression and high boost or reverse that if I want more low end.

So since I'm leaning to more high end, I want a smaller displacement engine which has the low compression and strap a fat turbo to it right? What combination would you guys recommend? How much would everything cost? Could I do it in stages?

After that I would like to swap out the tranny with a 6 speed and slap on some big brakes, but that's for a different forum.

Thanks.

But I want to give it back to my dad. His car sucks right now, and it's dumb for me to take the nice car with me to college where I wouldn't use it very much. When I get there I can get an old RS for cheap and then use the money I get from over the summer and working part time to make it quick over the next couple years.

If my dad had the money for a sti or S4, I would have no problem taking the rex with me

Why not save some money and buy a L? No point and spending the extra money to get a RS, then just rip the motor out of it.

Yup, if you're planning on doing alot of work, a awd L is the place to start. Mid 13's isnt hard with an aftermarket turbo on a RS.

Is the body panels the same on the L? I seem to remember that the lights and hood and of course the front bumper were different.

For those of you who have driven the different setups, can you describe what the driving experience was like in each? Turboed RS, ej20 swap, other swap, high boost, low boost, etc.

Thanks

Front bumper, hood, rear LSD(00-01 I think), engine, wheels, wing(coupe), suspension, exhaust, interior, gauges, and I'm sure there's more. At this point I wish I had gotten an L since I'm replacing almost everything that differentiates the two. With the difference in price, I could easily paint the whole car and make it look however I wanted it.

Im doing the L conversion... not likely a full conversion. But I too found it to be more cost effective. However, if you like having a nice interior, and a well running car for the time being, I would get an RS

I sat in my friend's RS the other day and I realized all the things I dont have. I dont have nice interior colors, sunroof, guages, spoiler, etc.

Someday I will have enough speed to forget all those little things. All in good time though

Default go with the L

Right now I'm swapping an EJ20 into my 94 L. I couldn't afford a RS. I to am a college student and this is actually about $2-3,000 cheaper than buying an RS not to mention it is easy to upgrade the WRX. The car is costing 2500 and the engine is 2400 shipped with t-bo, ECU, harnesses, intercooler, and all the piping. I am spending about $1000 more to update the front end of the car to look like an RS and to buy the rest of the needed parts. This method is a requires some time but I've got the summer, my engineering classes and friends with knowledge and skills that I can use. I would recommend doing the swap but what do I know I am but a lowly newbie. Good luck!

Default part I forgot

With some of the money that it would cost to turbo an RS I am going to finish the exterior and redo the interior.

EJ25 shortblocks are going for $800 new lately.. and that isn't even the best price.

Bullet-proofing the car is another matter.
It is all going to depend on how you approach the modification and driving of the car.

Make no mistake. Modifying the car to be faster is going to make it less bullet-proof, not more. Plus you will have to be constantly on watch for any kind of failure which could lead to a more catastophic failure.. In short, you will have to be absolutely paranoid.

Even if you are absolutely careful the worst can still happen.. broken block, cracked heads, disintegrating tranny.. Make sure that you are ready for this to happen. Keep an emergency fund on hand for emergency parts. Or you can do what a few of us are already doing and start stocking all and any parts that can and will break.

On a positive note, there are a few of the RS-T owners that have NOT broken any major parts, though I do believe we have all had our share of failures on minor parts.

On a second positive note, I don't believe that there have been many complaints from the EJ20 swap camp..
