Default a few questions about impreza models and which ones are good for turbos.....

sorry if this has been covered already. i apoligize in advance. i currently drive an older acura integra. but i plan to buy an impreza AWD and keep the engine as is until i can afford a turbo. need out of the honda scene. i want my car to be relativly fast, but i want good reliability too. is it best to get a 2.5RS and run low boost? or can i get a 2.0L and run higher boost and still have good reliability? i figure if i can drop into the high 13's, that is good enough for me. im not looking for a 10 second car here. and also, which years have the best engines? i heard the SOHC were better but i also heard people say the DOHC is better. i dont even know where to start looking for info. i browsed this site and found lots of good info, but i could always use more. thanks alot peoples.

You asked for help. That is the single best resource that we have. If you really want to educate yourself you'll get drunk on a Friday night and read it...

Excuse my fellow i-clubbers. The are really sensitive and mean to new members. That post that they refer to is a great source of info. The search feature is a lot of help too. About the turbo, everything will depend on your budget and expectations. You could get an aftermarket turbo(vishnuperformance, ludespeed, etc) and have a 2.5Rs with a lot of low end or you could get a EJ20 engine and do a complete swap. The 2.5 Rs seems to be a more expensive option. I am going the RS way because i love its torque. Both ways are expensive, but you can save a lot of money if you do your research and have some mechanical background. Everything will depend on what you want. Take a good look at your pocket and remeber about gauges, clutch, muffler, suspension, and all the other mods that you need. If you have any questions feel free to post anytime.

EJ20? is that the new WRX motor? i heard of people getting full swaps and motors for around 8000. that doesn't seem too bad to me. what kind of psi will you be running on your turbo 2.5RS? will as low as 4 or 5 psi still allow my car to move pretty fast? what other engine upgrades do you reccomend? will your car be a daily driver? what kind of times are you aiming for? i have read on another forum about someone who did a WRX engine swap in his 4 door impreza. 98 i think. he said that after a 1/4 mile he had about a full car length on the wrx. thats pretty good. but i also read that a 2.5RS turbo will wax a WRX quite nicely. sorry about my lack of knowledge here.

I am basically getting a short block from Cobb and a Vishnu Turbo kit. I will be running around 8psi. It won't be my daily driven car so i might turn up the boost to see what happens. It seems like you would be fine at 3 or 4 psi with an aftermarket turbo kit and a piggyback fuel system. You could produce around 230 hp without running into major problems After that you need new internals, and a stand alone engine system such as Haltech and Tech III, new transmission, maybe Limited slip differentials and so many little things If you have the funds you could get and STI engine with ECU and drivetrain. Vivid racing is selling a set for $9000.00 in the vendor forum. You have to let me drive it when you get it though.

ha ha, sure you can drive it if you come all the way up to ceenada eh? well, your advice is great. im learning more all the time. so i could prolly get a good turbo cabable of 8psi but just set it for 3 - 4 psi? or does it not work that way? one of these days i prolly will end up doing something else to it. ive seen 500+ hp out of the 2.5RS, but i doubt they are daily driven. i really dont know what route to go yet. not sure if i should dish out the money and get a 2.5RS or just go with an older base model. ha ha, well, i'll prolly decide soon enough. i hope anyways. thanks again for your advice. you seem to know your shiz very well.
