E28 524td Holset HX30w

[@bastienrigal416]

Bro this is incredible that’s a really high rpm diesel , would love to have some details !!

[@neesmuparedzeets]

It revs all the way up to 6k thanks to governor mod. It’s one of the cheapest and most efective mods to get more fuel from the mechanical fuel pump. All you need is a couple of washers or stiffer springs for governor and probably a new gasket for the top part of the pump 😁 stock governor starts to drop fuel around 4k rpm and after that rpms go up slowly up to 5k. With modified governor, you get very much fuel in all rpm range.

What happen to uploads

[@neesmuparedzeets]

Sorry, i’m just lazy as fuck when it comes to making videos and uploading them.

[@waffentreager6286]

Btw at what rpm does it start to boost and at what rpm does it hit full boost? Also did the hx30 fit directly to the m21 manifold with no modification?

[@neesmuparedzeets]

It starts to boost around 2000rpm, full boost around 2500-3000. I suspect that with ported head and rebuilt engine it should start to boost a bit sooner😂 i had to make an adapter from two t3 flanges that are welded together in 15degree angle to raise the turbo and tilt it to the side. I also modified stock e28 turbo oil pipes - basically just extended them. And welded different flange to stock exhaust and end extended exhaust couple centimeters so the flange is couple centimeters highert

[@neesmuparedzeets]

I have the biggest version of hx30w, versions with smaller compressor side maybe could be fitted without adapter.

[@faizmuzakki1312]

Is it stock hx30w? i exploring my option for my IDI 2.8 diesel that i would like to put turbo on, but hx30w is off of 3.9 diesel and mine only 2.8 and i was wondering how's the spool gonna be? is it gonna be laggy or not because mine is smaller displacement than 3.9 4bt

[@neesmuparedzeets]

It's stock turbo. But the biggest version of hx30w which is sometimes refsrred as Super hx30. It spools quite fast - around 2000rpm which is only ā bit later than stock 2.4td turbo

[@faizmuzakki1312]

@@neesmuparedzeets So i don't really need to worry about spool right? i mean mine is 2.8 and yours 2.4 spool around 2000 rpm so mine will also be around that number, logically. Thank you

[@neesmuparedzeets]

@@faizmuzakki1312 yes, should be fine probably. Exhaust side of hx30w is actually pretty much the same size as stock turbo

Привет, расскажи по сцеплению. От чего диск, корзина, маховик? Спасибо

[@neesmuparedzeets]

Single mass flywheel from 1982 520i m20b20. My stock dual mass diesel flywheel was making noise and i just had this one in garage. Clutch disc and pressure plate also come from m20 engine. Basically i just have stock m20 gasoline engine clutch. But needed to modify starter because m20 and m21 flywheels have different size teeth. everything is fine for now, except some rattling noise from gearbox when in neutral, because of lighter single mass flywheel.

Дядька, привет, сколько дует турбина и выдерживает ли голова, если говоришь по русски опиши точнее что делал и как с тнвд, буду благодарен

[@neesmuparedzeets]

1,3 bar, stock engine with intercooler, no problems with cylinder head so far. Blew one head gasket, but it was a cheap and shitty one. Injection pump has 11mm rotorhead from Nissan 2,7diesel, camplate from BMW 2,5tds and governor mod.

[@frani1236]

Hello from Belgium ! Where did you get the stiffer governor spring ? Can you please tell me ?

[@neesmuparedzeets]

@@frani1236 i didn’t get a stiffer spring. I just put some washers in governor to compress the springs.

[@frani1236]

Thank you for reply ! How many of them did you put? what kind of section did you use ? So camplate is from M51 engine ? I am planning the pimping of my my old tranny with pretty same mods … MLS head gasket, Raceware head studs, the VE upgrade with 11 or 12 mm elements and HX30 or HE221W.. She’s already intercooled… Did you install a better tank lift pump ? An exhaust temp controller ? Your advices are very welcome ! From the Belgian M21 lover

[@neesmuparedzeets]

@@frani1236 i put washers under two longest springs of governor. Don’t remeber how many exactly, but i can compress them just a little bit only, so the governor is very stiff 😄 yeah, camplate is from m51, rotorhead is 11mm from Nissan - part number - 9461618910 (needs a little modification, 2holes drilled). Otherwise stock engine with biggest version of HX30w, boost starts around 2000rpm, so not much of a turbo lag.
