few questions

car- 03 legacy wagon

question- how hard would it be to turbo the stock motor? Would i be able to use stock turbo, dp, and top mount from an sti/wrx?

Or would it be easier to buy a turbo motor swap?

I want to make about 250 to the wheels. Which direction should i go. and also the car is an auto slush box.

 

Buy a turbo motor and swap.

 

Yeah, that.

Look for a stock 2.5L wrx motor and turbo. With a good tune and the right parts 250whp isn't impossible at all.

Or you can buy a turbokit off rs25.com forums and do 5lbs of boost to get you there. There are kits for <$1500

 

how well do the stock motors hold up to boost?

how different impreza's chassis from legacy's?

 

They dont hold up very well.... as far as i know at least
Its the consensus that you buy a new turbo motor.

 

I don't know how many people have put a turbo on an N/A motor because there is such a ready supply of turbo motors. They really are completely different internals and with a turbo motor, plus Engine Management is all already done for you!

If you want to save a leetle bit of $$ you could look for a WRX 2.0 and put a VF 39 on it from an STi. With all the right add ons (Full exhaust and a tune) 250 whp should not be hard at all.

 

ok next question, where can i buy a wrx motor from. im not trying to spend $4.5 for a sti motor.

 

This may be overkill but it may actually turn out to be cheaper. You might want to trade the Legacy auto for a used WRX wagon, Sedan or even an Sti. If you start off with a turbo/5sp platform your options will be vast and actually allot cheaper.

 

i thought about that too, i just dont really care much about the looks of the impreza wagon. im loving the legacy. i think i might try see if i can find a jdm legacy gt wiring harness. and use a wrx motor and just upgrade the turbo and tmic.

 

If you like the legacy I say stick with it. Just be prepared for a few more headaches and some additional costs. You could go with a JDM 2.0 and hit your goals pretty easily. If you were to find a 2.5 motor it would be easier still.

 

hit up jhot in augusta. lots of cheap twin turbo motors from legacys

 

What's your budget for all this?

 

You need to upgrade the tranny as well

There ya go

 

i dont really have a budget, i am just trying to avoid paying almost 5grand for a motor and tranny. i am going to do a little more searching/research before i do anything.

 

we know you're a big fan of those ssh:

 

You could always get a sti short block and build it.

 

If your looking to avoid paying five grand for a motor and tranny you may not want to do a motor and tranny. :rofl:
