New to Forum, need some input

[Highlander]

Hi, first post here. I have a 2009 CRX7, well it's my wifes. The vehicle is bone stock. Have owned the car for 3 years. Purchased with 50k miles, now has 70k.

The turbo on it has broken, massive oil leak etc, no boost. Mazda have refused warranty. I have done some research on possible ways to get it back on the road again that lead me here.

I am looking to replace the turbo myself with either the cheap chinese unit at around 400.00, a rebuilt Mazda unit at 800.00 or a Stage 2 BNR unit at 1000.00. The BNR is for a Mazda 6. So should be a direct fit. Just a diff housing to give more top end hp at the expense of some low end Tq.

Looking for suggestions and input on best direction to go. I figure if i am going to spemd some dollars and do the work myself a nice boost in performance would be nice.
Will the BNR stage 2 require a tune? Will i lose a lot of low end grunt? I am located at 5500 feet so have a bit more lag than sea level. I don't want to get in deep, i am thinking better more powerful turbo with new intake would be enough.

Thanks in advance.

You will need a tune with the BNR.

Check for used OEM turbo on eBay...like this one : Mazda CX 7 Turbo turbocharger 2 3L | eBay

Youre better off with a somewhat used OEM turbo then a chinese knockoff...

Depends on if you want a little more power. If you get anything other than the stock turbo you need to tune. Don't go chinese on it.

Thanks for the welcome. Been looking at e-bay as suggested.
What do you guys think of this Mazda CX7 CX 7 2 3 turbocharger Turbo Billet Wheel Bullet Proof K0422 582 | eBay

Thanks again for input. I am learning as we go on this, my experience is with supercharged V8s so this is all new to me

This looks like chinese knockoff...I think you wont find cheaper than the link I suggested for an OEM turbo with low milleage

[btstarcher]

And you will need a tune with anything other than stock. So be prepared to shell out an extra $1k for supporting mods. Cobb AP, HPFP internals upgrade, tune.

Accessport won't work on cx7. But Versatune is good stuff.

Warranty extension maxed at 70,000 so SOL.

Grab a used OEM on online if possible. Then work on installing a banjo bolt, and an oil catch can. Both of those will help.

Wanna add powa? Then consider bigger turbo, a hpfp upgrade, and a tune. Freek and stratified both know Versatune, IIRC.

Then get an intercooler upgrade, intake, inlet pipe. Why? Power.

It's a slippery slope, very addictive.

Update, thanks for the help. I purchased the Mazda unit that was linked on here. Should be here soon. I have the Mazda back in my garage, the dealership had it stripped. Should be interesting getting it back together. Any pointers or links would be great. Thinking of buying a manual if required.
