So im running for now TD04HL-19t from volvo on 1.8t dbw engine with 8.5cr all good but wants moar
The k24 from 300hp volvo seems pretty easy to setup here
Anyone here had experience with that on a tiny engine?

19T an K24 Volvo Compressor are pretty much the same in case of possible flow.
If you run them on four Cylinder 2.0l Volvo Turbo whiteblock engine from SV40, you will get around 330 to 340 real HP.
K24 Turbine is smaller and 1000 degree rated, enabling you earlier boost if rest of system is capable of that. VVT helps a lot.
I guess your 1.8T has no VVT?
In Volvo Engine you have a lot more EGT and Knock with K24 on fixed Valve train. Should be the same issue for 1.8T.
Be sure having enough fuel ready to delivered. Older Volvo Engine with fixed valve train needs around lambda 0.72 to 0.74 in knock area. Top Lambda depends on EGT of course, but is mostly around the same target to stay under 1000 degree in Volvo.

People use K24 on 1.8t on Audizine , if you wanna ask there,apart from that cant say much else except that AFAIK the porsche flanges wont bolt up to stock manifold.

Not so much with the older BW stuff myself but this mk1 was running a 1.9 KR 16V engine & K27 at nearly 2 bar so you should be okay with the smaller one. I'd also suggest looking at the Holset's too if ur swappin mani out, can get some cheap ones from their Wuxi factory on Ali, HX30 should do 36lbs/min or you can get a HX35 with 8/9cm turbines. https://www.youtube.com/watch?v=GXCryn0rrjQ |

...because soon you may want more, I suggest TD05H20G 7cm2 or 8cm2. |

Volvo K24-7400 makes around 340hp on pump fuel and spools about the same as the oldschool K24-7000 from 2.2T.

well its definetely larger but looking old style with huge center hub VVT was removed some time ago but can be returned ofcourse  Not so much with the older BW stuff myself but this mk1 was running a 1.9 KR 16V engine & K27 at nearly 2 bar so you should be okay with the smaller one. I'd also suggest looking at the Holset's too if ur swappin mani out, can get some cheap ones from their Wuxi factory on Ali, HX30 should do 36lbs/min or you can get a HX35 with 8/9cm turbines. https://www.youtube.com/watch?v=GXCryn0rrjQThe thing is that im already at T3 mani with volvo adapter to TD04 flange. Doesnt want to global mods here so this is only pros of K24 for me cons: rare, expensive, 80s technology, servicing? I like the holset option and for now im in process of online tuning car with HX35W installed on 2.0 stroker so waiting for result But ive never had oil cooled turbo so oil cooling should be done for that and a lot of changes in the bay And the main question - is this chinese turbos able to hold up 2bar boost without chinese things? ...because soon you may want more, I suggest TD05H20G 7cm2 or 8cm2.
Totally different flanges etc |

Why dont you try the He221w? It outflows the k24, does much higher pressure ratios and better efficiency islands aswell. One of the best small fast spooling capable turbos. If you already have a t3 manifold , you could use a t25 adapter.

"Totally different flanges etc"
--------------------------------
it comes with many flanges: subaru IHI style, T3, Toyota style, Mitsubishi style...in case you will fabricate new exhaust manifold, you even could combine flanges. I made mine with IHI-T3 integrated pattern flange, as an example. Just saying!

Ok, maybe "size" was wrong description.
It is the Turbine AR which produces the mentioned problems.
Maybe along with bad dynamic behavior due to missing VVT.
But i only guess that you will have the same problems.
So if arund 340 Hp is enough for you, you can give it a try.
Possible Volvo K24 Upgrade ist K2480 Compressor on original Turbine (+30 Hp) or TTE 400 Hp Upgrade.

Why not TD04HL-19t from Kinugawa?

China Rubbish in my opinion. But as of its nature cheap  Had two major failures right after install and after few kilometers, but years ago. Maybe better these days... |

Holsets are designed for high boost, although on diesels, but many have used them at high boost on various petrol engines no problem. Turbine side sizes can vary massively so you tend to have to make sure you spec it right and a few other niggly bits like slightly different flanges, high boost pressure wastegates, wg's slaving off one runner etc The old China arguement tend's to be a fallicy at times, massive companies like that go for top quality ISO standards as they are producing so many they'd lose far too much money if they kept failing, I spoke with some companies to make custom parts like stainless steel cast exhaust manifolds, with all the quality standards cert's etc and prices came to around 30-40% of what I was quoted in the UK. There a few copies about over there though, proper ones tend to have the Wuxi or other Holset factories details on the labels like these - if I remember right these, or there was/is tons about like this, is due to them being used for excavation machinery who, being underground, had to change to water cooled turbo's for fire/health and safety reasons - hence the barely used and funny paint schemes. Been a few years but that's what I remember. https://www.aliexpress.com/item/32808187709.html?spm=2114.12010612.8148356.3.157a1c70ZVilrJ |

in fact now im looking for a holset one  Why not TD04HL-19t from Kinugawa?
im running genuine, stock turbo and 7+7 comp wheel and then 9 blades turbine wheel and gtx 11+0 comp wheel until its blown recently they are nice but i missed with an engine internals - its 1.8T with CR8.5; TD04 surges until 4200rpm then pushes up to 5500 and finally tapering down pretty fast. so this ~1500rpm window not what you want in a daily car for sure im not good in all that engine science, but i see here that TD04 should be used with less displacement as top-end turbo or large displaement where it didnt surges and made a smoot mid curve correct me if im wrong im really not familiar with all of that things China Rubbish in my opinion. But as of its nature cheap Had two major failures right after install and after few kilometers, but years ago. Maybe better these days... Same here Installed GT2971R style chinese on friends S3 and shit blows after a 10kms of 1.3 bar boost. The genuine one lives 2 years for now Thus reason of lil scaring chinese turbos but seems like holsets ok Imagine how this fcker fires up at the first start  |

Exactly. I have a t3/t4 china and no issues so far, even ran full 1.8t full oil pressure thru it first starts( needed to clean afterwards) but otherwise no issue so far after 1000km ish, but dont push it above 21 psi. They run 2-3 years with hard abuse or 40000-50k KM I say they are well worth the money for that. Then you either get a new one or get a repair kit for 30~ bucks and run another 2-3 years. The smaller HX30 variations easily get overshadowed by the HE221, look it up a genuine one can be had from Wuxi or Huddersfield for around 300+ bucks. Few vids on 1.8: https://www.youtube.com/watch?v=FSg9Pqk0Mmchttps://www.youtube.com/watch?v=JCi8HYbLaTcAlso if you have the time and want to do something "special" you could try using a VGT holset on 1.8T. Holsets VGT construction is much more robust than conventional Garrett, the vanes dont rotate but they slide axially instead, and they are rated for much higher temps, so could be a great project. |
