Good afternoon everyone!

I have just purchased this turbo to go stage 3 on my ST180

https://www.ebay.co.uk/itm/327043936983

I was wondering if this turbo is any good? After speaking to a tuner they said

"With regards to the turbo, we have tuned with one of these turbos before, they have upgraded internals over standard, but perform only slightly better than a stock turbo with pretty poor results, I can't really recommend using that turbo personally, you certainly won't be seeing near 300bhp "

From what im aware turbos like the s270 and x47 reuse the orignal housing, so what causes this one to not be able to push the same power?

My end goal is to make more power than standard turbo but i dont plan on pushing it hard as to cause potential engine damage. I was looking for the 300bhp sweet spot

I guess my question is is this a good purchase? or should i look for an alternative turbo. I can't refund it as it has already been posted.

I appreciate any advice, many thanks.

I thought you could refund anything bought online, in line with consumer rights standards

Check Ebay return policy I think you will find you can return it no problem but may have to pay the return postage as it is not faulty or damaged.

Sounds like it would be a good idea to discuss your requirements with an established tuner and get some recommendations.

If you're not already on it, the specific Fiesta ST site has plenty of posts on Mk 7 mods.
