How much does it cost to have a shop change the turbo to a hybrid system? Labor wise?
im looking for 300-320 wheel tops. Probably will need e30 to get close to that number. what turbo would you suggest for that power goal? And would I need to add or change anything in the fuel system to reach that?
can't recommend enough reading as much as you can on this forum before making any big ticket/time intensive purchase. read through the s280 turbo thread, any number of the hybrid turbo threads, and the uprated bosch injector thread.
pretty much filter out anything before 2020 when it comes to turbos/fueling. there's really good info, no doubt. but a lot of it is based around aux fueling since no one had tried uprated injectors yet and the s280 really hadn't won the community over before 2020. garrett was really the only reliable big turbo kit in town until turbo technics came out with their s280. Even still, the s280 isn't a true BT, it's just a lot bigger than the hybrid turbos that get put on our engines.
also i'm not knocking your choices, but you *really* need to decide how important hitting 300WHP is to you. getting turbos to 260-280WHP is pretty straightforward and the stock Fiesta can handle it well. that last 30-60WHP is something you're never really gonna see in responsible street/backroad driving and you're going to have to upgrade a lot of things to get good reliability.
lol, all that said i really wanna hit 330+WHP too and all my plans are to that end. good luck!
also a quick list of turbos you'll come across on this forum from biggest (and coincidentally most expensive) to smallest:
Garrett g25-550 (waaaay outta most people's depth and the Fiesta engine cannot handle what this turbo can dish out...but some brave souls still try)
Garrett gtx2860r (the true big turbo that some Fiesta tuners here love. a lot of lag compared to what's below here but it's ball bearing turbo with a long history and great pedigree)
TurboTechnics S280 (journal bearing big turbo that most tuners here swear by but don't just go by what people say, do your own research; way better on lag than a Garrett and more linear power/torque delivery than a hybrid turbo)
pumaspeed x47(r) ("we don't talk about pumaspeed" "they who shall not be named" ; they are one of the biggest players in England but had some serious issues at one point with their hybrid turbos and screwed over the North American market pretty bad on their exit. there are tuners here who still run and love the x47 platform and with the British Pound cratering in value it's a lot of turbo for the amount you have to pay for it. i've read that pumaspeed fixed whatever issues the original turbo had but not sure. that said you won't get as much support troubleshooting it since there aren't that many people in the States who have it)
whoosh hybrid (the gold standard in hybrid turbos in the States. great value and can keep it simple and just swap the OEM turbo with the whoosh and you're getting 260ishWHP instantly without having to change anything else. that said it's been argued the S280 install is just as straightforward and the whoosh hybrid does have a ceiling. you can push it past 300WHP with ethanol mix and uprated injectors but a lot of the tuner crowd here recommend against that. you're sacrificing reliability for power in ways you don't have to with other turbo systems. however if you decide you're good with 260-280WHP you can't go wrong with the whoosh.)
