Unfortunately, the first link has a min order unit for 10, second has massive shipping, however you can find the same turbos on aliexpress with decent shipping, also genuine or fake holsets for competitive prices. By the way, Pulsar turbos are great too. Again, for a ~500 bhp the best "budget" setup you can get is a twinscroll HX35 IMO. Hybrid KO4's for 1k euros + is so not worth it in my opinion. |

lol hx35 will spool tomorrow.
500hp on 1.8T totally pointless. Maybe for drag racing when you are limited by engine size or some other weird limitation.
No matter what turbo you fit on that, don't expect any meaningful boost until 4200 rpm, if the 500hp are actually real. And better upgrade the cams/valvetrain to rev to 8000+ rpm if you expect to hit any shifts at all.
This is completely not driveable on the street.

1st link do single unit items. If you've/op got a built engine, big air, big fuel, then it seems pointless choking it with a tiny air pump, let alone paying a fortune having said pump made less strong just for a bit of better flow given options or costs of custom housings etc. HX35 too big unless as prj said, you mod rpm/valve train. You can get hx30s with small hotsides, I think 7/8cm, 35's & 40's tend to start at 10/12cm. Pulsar are same too, all made at same factory in wuxi i think when i looked into it. Gtx28 60/63/67 all good for a built engine, these copies being used a fair bit, just different prices stuck on. |

Exactly, these hybrids usually keep the circle style exhaust housing , and mostly stock exhaust housing+porting for bigger wheels, which will severly limit flow in high rpm. I have seen twinscroll(proper exhaust maniflolds ofc) HX35 on 1.8 be at decent boost by 4k or before, single scrolls 4200 and so on yes, however why would 500 hp peak at 6-7k be not driveable for a fast street car, you wanna go fast ? You can, wanna daily below 4k? you can. I know nefmoto started with 2.7's but come on. Cheap NA cam combined with VVT is an absolute banger value for a valvetrain upgrade.
I guess what I am trying to say is that I dont really see the point of these expensive hybrid ko4's except the easy of mounting I guess, you are moving the powerband up anyway, will be limited in top end most likely, reliability is a question ( what kind of chra, uprated bearings do you use etc.), I guess we can agree on that no?

sorry all, the 1.8t is a joke unless your car weighs 1000kg or less
ya, you can motor around town with 300hp or so and still have decent torque, but otherwise... big turbo high hp 1.8t are boring AF IMO

Kek, classic  If only you didnt have to take the half the car down to do anything in a b5 with a 2.7 |

The 1.8T is just not too interesting when any modern 3.0 TDI is faster with a good stage 1 map.
I wouldn't bother building anything below 600 hp these days, preferrably on automatic transmission. There's just too many stock new cars on the street that are going to wipe the floor with you with zero effort.

Fair point, an Ibiza 6k2 really rips with a 20vt. Though i'd be more than satisfied with ~320hp on my 1.8T as a daily driver and still maintain low end torque/driveability. |

Every now and then i drive a 3.0TDI stg1 quattro machine, but it's like comparing apples to oranges IMO. 1.8T machines are dirt cheap, maintenance and parts are dirt cheap aswell. Driving a Quattro 3.0TDI is not. I, as a student could hardly affort those running costs of an A5 for example. |

Exactly, it also highly depends on your area, city and laws. Like for example here after 2L of displacement you start paying multiplicative taxes. A 3.0TDI tax is literally 12x higher than a 1.8L , its complete bullshit I know but it is what is, also there is no way you to get around it unless you wanna be a criminal  Then area /city I am not sure how many new cars people are buying with power that can keep up with 400-500 hp 1.8T's especially from a roll in your areas but, in my city people are still running around with 1.9TDIs and shit so owning a 400 hp 1.8T would beat or keep up with 98% of the cars probably. Either way kinda derailed the topic, but interesting discussion. |

That is exactly my point, the cost of literally just owning a 3.0TDI machine here is at least 4 times as expensive as opposed to owning an 1.8T. Than we haven't even discussed running costs. I could dream of a owning a 3.0TDI but right now is out of the question. We also still have plenty of 1.9 PD engines around and 1.8T's. Low running cost, still plenty of fun and life in them.

I have decided to save up some more and go the K04-023 hybrid route.
I figured pushing the limits of the rods on K04-001 hybrid would be stupid, and doing rods for just this would also be a waste.
So I'm planning on getting rods, and a hybrid 023 turbo. Anything else I should look out for? I'm hoping to get a stock 023 manifold, as i have no clue where to get a chinese manifold machined properly. Hopefully OEM 023 coolant and oil lines will fit, but time will tell.
Don't really care about raw horsepower, as such a setup should be plenty of power for a daily driven FWD.

I guess it also depends on who is at what stage in life. Though TBH, if you're able to properly calibrate ME7, never mind do ASM stuff, you shouldn't really be struggling for money, or if you are then you really have the wrong dayjob. |
