*Reminder - all the data gather here are from many sources(automotive forums, websites, my first-hand experiences).
PHYSICAL LOOK
JB-JL(top) vs JB-DET(bottom) in the same engine bay |
- Intake - Bigger intake plenum for JB-DET
- Cam position sensor
- JB-DET - use coil on plug layout | JB-JL - use 2 coils wasted spark layout
STANDARD TURBO SPEC
JB-JL turbo(top) vs JB-DET turbo(bottom) |
- RHF3 VQ29
- RHF3 VQ27
JB-DET turbo
- RHF3 VQ37 twin scroll
- RHF3 VQ42
* This is all I've got, maybe got some others more.
ENGINE INTERNAL

Okay, that concludes all of my findings about these JB series engine comparisons. These findings help me a little bit on making a decision to bought JB-DET engine over JB-JL engine after my old JB-JL engine blown. JB-DET is an improvement over the previous model which is JB-JL, and also to solve JB-JL minor reliability issues.
Tomorrow will be a new post about my engine conversion update. If I'm not lazy

What is the RPM that a standard RHF3 started to spool? If it is fully tuned, what is the RPM that the fully tuned RHF3 started to spool to create a boost?
ReplyDeletearound 2k rpm rhf3 spool giving boost already.what do u mean by fully tuned rhf3?
DeleteI mean, what is the spool time of a fully upgraded rhf3? How about the spool time of rhf4? Is it the same as rhf3?
Deletei dont think rhf3 can go any further that it is...there is a lot of types from rhf4...can u be more specific?
DeletePeople said smaller turbo such as rhf3 spool faster than bigger turbo, for example rhf4 and rhf5. So compared to rhf3, how fast rhf4 spool? Also it is said that twin scroll turbo also spool faster than normal turbo so twin scroll rhf3 spool faster than normal rhf3?
DeleteWhat are those vq27 and vq37, are there different sizes of rhf3?
for sure smaller turbo will spool faster than bigger turbo..its all depends on ur needs. vq term after ur turbo name is just to show in dept characteristic of ur turbo..nothing that ur eyes can spot the differences except maybe the flange.

hi,
Deleteits hard to determine by just reading. but of your gear changing in 4500rpm and your redline is 8000rpm. i think its normal for your engine maybe.
where are you from sir?..maybe i can suggest you to visit reliable and knowledgeable workshop around your area?
Boleh tahu kelebihan enjin l9 Dan perbezaan l9 n l6

DeleteHello there, do you how to modify RHF3 VQ38 into RHF3 VQ37 (twin scroll) into standard JBDET engine? what need to be replace or install?
ReplyDeleteHello there, do you how to modify RHF3 VQ38 into RHF3 VQ37 (twin scroll) into standard JBDET engine? what need to be replace or install?
ReplyDeletehi there, all you need are the turbo itself and turbo manifold that come with twin scroll turbo. its just pnp if you got that 2 items.
DeleteHow do you mean pnp for the twin scroll turbo?
DeletePlug and play✌��
DeleteBos kat mana nak cari timing chain l9. N biasa berapa harga
ReplyDeleteBos kat mana nak cari timing chain l9. N biasa berapa harga
ReplyDeletetiming chain L9?..boleh try tanye KP gasket..
ReplyDeleteJB - DET gasket kit and timing belt ada shop jual? Boleh bantu dapatkan address..
ReplyDeleteJB-DET x gune timing belt. gasket kit boleh try search for "KP gasket" kt google.

Deletesaya pkai kelisa,enjin 1.0 gearbox paw..n then d tukar jb det 4piston (A)..enjin ni bole fight enjin storia 1.3 ke?minta pendapat kwn2
ReplyDeletehehe..depends on mod and 1.3 pye mod..
DeleteSlm..mcmne nk buang immo kt ecu..enjin jbdet xleh nk start
ReplyDeleteSorry..time saya swap jbdet..xde plak immobiliser kt kunci die..kunci besi biase je
DeleteSlm pecinta enjin daihatsu & salam en.Rizuan,
ReplyDeletesaya ada beli 1 set enjin lantai L9 JB-DET utk d pasang kat kenari sya.
Pertanyaan;
Adakah L6 JB JL & L9 JB DET guna Timing Chain kits yg sama? Atau boleh guna Myvi? & Lastly Kat mana kedai local boleh order/beli?
Tuan2 share ke email saya:
heartday.john@gmail.com
sudah di share..tq
DeleteNak tnya sy pkai kelisa 1.0 A. Plan nak tukar enjin jb-jl kwn punya.. soalannya xmnyesal ke nti tukar ke 660t sbb 1.0 mcm lg power.. ada sapa2 yg da tukar enjin masuk kelisa?
ReplyDeleteBaik stick 1.0 atau kalau nk tukar pon naik 1.3 na or turbo..x berbaloi turun cc semate2 nk turbu
Delete1.0 54hp, 660turbo 64 hp. Pikir2 la sendiri. Masing2 ada advantage, 660turbo mmg sesuai utk acceleration sebab dia 64hp, lepastu pakai close gear ratio gearbox. Tapi top speed hampeh la 120kmh kat 5.5k rpm kalau tak silap. Kalau enjin 1.0, pikap boleh la , top speed lagi sedap sebab gear 5 nya lagi panjang sikit . 120kmh kat rpm 4.5k kalau tak silap.senang cerita , 1.0 sedap main highway, 660 turbo sedap main acceleration
DeleteNyesal x sudah..tpi enjin jb liat nk kondem
DeleteBos,andai enjin jbjl,klu nak pakai turbo l9,just pnp atau kena modified?
ReplyDeleteBos,jbdet can use jbjl timing chain & gasket?
ReplyDeleteSalam bro Ridzuan, sy pakai enjin l9 JB-Det, dah 1 tahun lebih pakai then, baru perasan dkt sambungan intercooler tu ada licking minyak. ape masalahnya tu ya? turbo standard rhf3. kene servis turbo ker?
ReplyDeleteAssalam boss sy pakai kancil tukar halfcut L5 jbjl. Turbonya baru je tukar. Enjin sy dh kong, pomen suggest tukar ke enjin kosong L9. Pnp saja ke? Kalau dh masuk enjin L9 xpe ke pakai turbo L5? Nk kene tukar apa je ye? Terima kasih.
