EJ20 N/A to T?!

[niky]

*niky: although nasioc means north american subaru impreza owners club, since it is the biggest subaru forum in the world, the members there aren't just from america and there are also american owners who was a 1999 impreza which is a 2.0. and yes i agree that speedlab and orange are very great tuners, but just like i said it will be cheaper and safer in the long run if he does a swap.

Just letting him know that we have local people who know the car, as well. ;)

And I agree, as i also stated... safer lang mag-swap (ng car. ) in the long run.

*zeepey: if you want a swap go to fuzionR at e.rod. also i agree with jdrex better to do some suspension mods. i'd rather have a slow car but handles really well than have a fast car that can't turn at all. plus with a proper driver on a lightly modded impreza can outrun an STi on the track. going fast on turns is more fun than going fast on a straight line.

It's the man, not the machine. :tup: With my heavy-ass car, with simple IHE and chip, on toasted brakes, I was just 2 seconds slower around the track than a modified STI with around 400 ponies. Of course, I had more experience than him... so there...

Focus on working on the suspension, lighten the car a bit, and do simple mods (the chip and headers) to give you a little more punch out of corners, and that's it.

thank guys for all your opinions and infos you shared! After some sleepless nights reading on the net, i'll go for the simple and basic engine upgrades and suspension. Baka that alone will renew my enthusiasm with the car hehe...besides, i might sell my car to my brother next year. atleast it stays in the same house . I already purchased a set of springs. Bushings and struts to follow.

Agree, that's why when i got my sti first thing i did was go to racing school that had 2hr class for 6 days and went to as much track days as i can before i modded it. Now i'm not a great driver yet i still have lots to learn but i can
hold my ground with a proper car.

Orange is a very good subaru tuner, they evn make thier own mods for a very reasonable price.

sir may bmw 325 ka naman un nalang track car mo.

Why would it not be safe to turbocharge a naturally aspirated EJ?

The naturally aspirated EJ is no STi mill... hell... it's not even close to the WRX mill... but a low-boost set-up with about 7-8 psi is relatively safe on that motor.

Speedlab has aftermarket manifolds built to bolt up to the engine already. All you need is to source a turbo and the other parts.

The only problem with turbocharging an NA Impreza is that you will never get the same amount of power as a stock WRX reliably without spending a lot on internals. The N/A Impreza has a higher compression ratio, weaker engine internals and a weaker transmission. If you boost it to the same 14 psi as a stock WRX, expect stuff to break.

At the 8 psi you can run, expect to have around 20 horses less than a stock WRX.

If you want more power, you'll be buying new pistons, new connecting rods (around 100-200k pesos, I believe)... perhaps a reinforced gearbox or a gearbox swap from a WRX or WRX STi... actually... you might just want to buy a WRX engine secondhand and swap it in... or better... swap your car for a WRX.

But if you don't mind being "slow", turbocharging your stock engine is fine. Sayang nga lang pera... you need around 200+k for the base turbokit... then you'll spend another 200k reinforcing everything... might as well just trade-in.

-

N/A mods... full IHE and chip... will probably get you the same WHP as a stock Lancer... ...problem is the AWD is a big drag on the engine... which is why the Impreza really needs a turbo to come alive.

-

Suggestion: Why not trade in for an older Forester XT (the boxy one)? Comes with a stock turbo, a huge trunk, a double sunroof and an automatic. The four-speed AT and stock bottom-end can take 400 hp.

safe po talaga kung 7-8psi lng for DD use lng namn?ok na sakin un...i want extra power on my 2.0r nabibitin na kc ako sa stock pull...

AT or MT? If it's MT, possible. If it's AT, possible still, but I'd advise against it.

MT po sir...

[niky]

MT po sir...

Turbocharging is possible. At light boost, you can probably get another 50-60 hp at the wheels.

anu po ba pwede turbo sa 2.0r?

Ilan ba stock WHP ng Lancer EX and stock WHP ng Impreza 2.0?

[crash_kid]

Ilan ba stock WHP ng Lancer EX and stock WHP ng Impreza 2.0?

stock lancer ex may be 130whp, impreza 2.0r i think 108-110whp,130whp with IHE plus tune...impreza has lower whp becase its AWD,but better traction...

[McQueen]

^ both M/T transmission? I hope someone can confirm this with dyno sheets of those 2 cars.

[niky]

From what I recall, yes, that's about right. And both MT.

Better traction doesn't really matter on the road at these power levels. It only becomes a big performance issue at between 250-300 hp... but a 250 whp front driver is still driveable.

The right turbo is whatever fits your budget and power goals... but if you're shooting for STi levels of power, better to just start with a WRX or an STi already rather than overstress the regular EJ20.

no sir,alam kong malayo sa sti power...all i want is extra pull,additional torque...bintin kasi ako sa awd with just 150ps from 160hp FWD,hehe...
pwede ba sir wrx turbo or yun mga IHI turbo ng sti 2.0 engine?

Possibly, if you can find all the components from a WRX system, it'll make the install easier. I don't know if I'd shoot for a full STi set-up without upgrading the motor internals or the transmission.

[McQueen]

I heard that speedlab's turbo kit for the new Lancer M/T can go up to 230 whp (doesn't say kung ilang psi). I wonder if the NA impreza can reach that whp as well? and in terms of reliability and durability; EJ20 or 4b11? (with both engine having turbos. i know the engine isn't made to be turbo'd but still...)

kahit siguro mga 200whp ok na sakin un...

There is nothing much you could do to a NA 2.0. Upgrading the car will save you time, money and heartaches unless you love stress
