Re: wrx conversion

can only echo whats been said.

the price of the parts alone is way more than a wrx would cost you to buy, then add the trade in price of your current car and your saving a fortune doing it that way

Re: wrx conversion

Well, you'd need all of the above excluding bonnet and dash dials. So enigine, complete drive train, suspension, full brake set up, wiring loom and probably other stuff I'm missing off the top of my head. You'll need all the above to have a car that is safe running the power of a WRX engine. Standard brakes, drive train and suspension on a N/A Impreza won't be up to the job and for safeties sake as much as anything should be fitted.

Is there a reason you can't get a WRX/Turbo Impreza such as location?

Re: wrx conversion

its mainly location.... taxes on vehicles are exorbitant, brings it to about 3 times the orig price (no i am not kidding), might just be easier... i'm really just getting more info to see what my options are...

p.s. my 2004 TS feels really sluggish compared to my last car (2001 focus 1.6l)... i know the engine is smaller (1.5)but i jsut somehow didnt expect to feel that great a difference... is there any place in particular i shud start getting inspected for the cause of the problem e.g. spark plus / transmission etc

Re: wrx conversion

Is your Impreza AWD? If it is that adds a lot of weight to the car as well as more potential for loss of power through the drive train. That would go a long way to explaining the difference you feel in the power.

You could do a couple of things to maximise the potential of your engine. Make sure it is regularly serviced with regular oil changes, check the plugs and leads etc. Also try fitting a decent after market panel filter to help the car breathe better as this will improve responsiveness if not outright power.

Re: wrx conversion

its not AWD as far as i am aware... this feels like a dumb question but would the fact that its an automatic also lead to any loss of power...
