BMW e90 320d xdrive conversie

Recommended Posts

Dupa ce m-am bucurat un an jumate de pachetul performance de la motor m-am decis sa fac un upgrade mai serios. Masina are deja amortizoare Billstein si arcuri Eibach pro-kit, discuri de frana Zimmerman si placute ATE ceramic, volan M cu padele (functionale) si tobe de 335 pe pachet M. Deci, nimic de adaugat in rest. Uite asa am trecut la studiat ce e de facut la motor. Nu sunt un fan al scoaterii DPF si obiectivul oricum sa ajung pe la 240-250 CP. In cazul asta exista varianta cu chiptunning sau, ce am ales eu, o conversie la 325 cu chiptunning care m-ar duce spre 250 CP si 550 Nm. Ce inseamna asta sau mai exact cum se face, pai inseamna sa gasesti un motor de 23 (posibil donator X1 sau seria 1) dupa care mutate turbinele cu tot ce e nevoie, calculatorul si injectoarele plus alte chestii de pe donator pe masina mea. Treaba e in lucru acum si miercuri sper sa fie gata si sa va tin la curent cu rezultatele. Ma astept la un 0-100 pe la 6 secunde si un top speed pe la 250. Abia astept sa o vad pe strada cu noile chestii si dupa aceea vedem ce mai urmeaza ;) daca aveti idei bagati aici. De exemplu cred ca voi adauga niste prize de aer pe capota ptr o racire mai buna. Urmeaza frane de 335 ptr ca o sa am nevoie...

Pai asta fac acum. O sa aiba doua turbine, injectoare de pe motor de 204 CP si intercooler mai mare. Cu totul o sa ajunga pe la 250 CP si o sa aiba un cuplu rupere. Ma bate gandul sa ii pun si un grup nou dar sa vedem intai prima isprava gata. Va tin la curent cu proiectul ;)

La cutia de viteze te-ai gandit? sau convertizorul din pack-ul performance e acelasi cu cel pus pe motorul de 204cp?

Aceeasi intrebare si pt xDrive/cutie de transfer.

 

Mi se pare bataia dracului de cap sa faci conversia asta, sa nu mai zic scump. Cum a zis si Cristian.O mai sus, nu inteleg de ce nu iei un 330/335d si ai terminat balciul. Sa nu-mi spui ca e impozitul mare si consuma mult :laugh:

Am deja convertorul de cuplu mai mare, intercooler si racire ptr mai mult. Ambreiajul poate fi o problema dar am deja Sachs pe lista si daca nu imi place ceva il schimb. Nu vreau sa schimb masina ptr ca tin la ea. Put si simplu ma joc si vreau sa vad ce pot face safe pe ea. De aia si folosesc doar piese BMW si solutii verificate. De fapt ce am explicat eu pe scurt aici face Alpina. E deja verificat acolo si nu ar trebui sa fie probleme. Singura necunoscuta este cum va functiona pe xdrive. In rest totul e verificat si ok. Promit ca daca e totul ok sa vin cu ea la o intalnire. Pur si simplu e un proiect de suflet. Conduc e90 facelift din 2008 si masina asta mi-a placut mult de tot. E al treilea e90 ;) daca proiectul asta iese bine mai am trei chestii pe teava dar le voi povesti la timpul lor ;) si da, era mai simplu sa o vand si sa iau un 330 dar nu asta era ideea ;)

Daca nu duce automata o sa vad. Personal ma astept sa duca. Standard avea 420 Nm si acum o sa ajunga pe la 500-550 Nm. Deci, nu ma astept la probleme. O sa vedem. Azi s-a facut transplatul pe motor. Mai exact motorul meu a fost dat jos si echipat. Sunt si niste tevi de modificat ptr a se potrivi cu noile piese. E poveste dificila si migaloasa. Maine se pune la loc si se conecteaza electrica. Daca e timp se face programarea. Vedem dupa rezultatul ;) Edited by crisjohn

S126 e convertorul de cuplu de pe PPK si in teorie e cotat la 450 Nm. Pe motoarele cu indicativ 23 se pare ca e un alt convertor din gama P. Oricum exista o marja de 10% deci pe undeva in jur de 490-495 Nm ptr S126 cum am eu pe masina. In principiu in treapta 1 si 2 o sa folosesc o limitare de cuplu in soft... cand o sa fie gata o sa ma joc cu ea si vad cum merge... vis a vis de convertoare oricum e o poveste lunga si fiecare motor are un convertor specific pentru un anumit mod de functionare. Convertorul prin constructia sa poate ajuta motorul sa urce mai repede in ture in zona optima sau sa transmita mai multa putere la roti... e o intreaga teorie si la americani in special la alergatorii de liniute e o intreaga poveste pe aceasta tema. Daca o sa am probleme pot ori sa limitez cuplul din soft ori sa pun un alt convertor si din ce stiu eu cei de la ZF vand si piesa singura (vorbeau niste baieti pe un forum Alpina). Edited by crisjohn

Convertizorul din PPK e acelasi cu cel de pe .23d (24407588746 - S126, cum ai spus si tu) si acelasi care e pus standard pe .20d de 184CP.

Probabil ca poti pune si alt convertizor, nu mi-am pus niciodata problema asta, mai ales daca esti dispus sa investesti multi bani in proiect.

Tobele de 335 au fost un proiect interesant pentru ca a trebuit sa adaug si punctele de prindere sub masina ca si la 335. A trebuit sa adaug izolatia si toate protectiile de sub masina si am abandonat spatiu suplimentar din portbagaj. Sunt cu circuitul intreg din fata pana in spate cu toba medie si cele finale de 335...

 

Cu cutia am cateva idei si daca nu duce o sa trec la planul 1, limitare cuplu la 450 Nm. Planul 2 e schimbare convertor cu unul de motor 23 adica familia P daca nu ma insel. Se poate lua de la ZF sau de pe o masina veche. Oricum la Alpina D3 convertorul duce maxim 100 K Km din ce am citit si lumea il schimba. Vreo 385 Euro costa nou sau reconditioneaza cu 280 Euro. Varianta hardcore este sa scot curba de cuplu si putere a motorului sa o trimit in State si sa imi faca unul la comanda cum vreau eu. Si eu am emotii dar cand te mananca te scarpini :)

335 ii biturbo si din fata pana in spate vine cu 2 tevi pe cand 320 are numa 1. Si eu mi-am pus evacuare dubla si am schimbat tot de sub masina cu piese de 335 dar evacuare in sine am facut-o custom.

 

De aceea te intreb ca is curios cum ai facut adaptarea si ce puncte de prindere ai folosit.

Si cati km tine cea reconditionata?

 

 

Cei de la Alpina spun ca inca 100 K... Ideea e ca cine isi ia Alpina o cam alerga si de aici apare problema... Oricum convertorul are un rol mult mai important decat credeam eu la inceput. Nu face numai o simpla adaptare a cuplului ci are si un impact in transferarea eficienta puterii motorului... In teorie cam asta face:

"In modern usage, a torque converter is generally a type of fluid coupling (but also being able to multiply torque) that is used to transfer rotating power from a prime mover, such as an internal combustion engine or electric motor, to a rotating driven load. The torque converter normally takes the place of a mechanical clutch in a vehicle with an automatic transmission, allowing the load to be separated from the power source. It is usually located between the engine's flexplate and the transmission."

 

 

Oricum cutia mea GA6HP19Z e aceiasi de la 123 D deci ar trebui sa mearga direct si sa nu fie probleme. Deasemenea combinatia mea, adica cutia aceasta cu S126 se gaseste pe X1 23 xdrive ;) de aici a venit ideea :) daca tine pe X1 23D xdrive programul de la Hartge, sa zicem care ofera (http://www.hartge.de/e/bmw_motor_6079.html) atunci tine si nebunia mea.

 

Mai jos extrase de la diferiti tunneri pe motorul, cutia si convertorul in cauza:

 

Hartge

 

Engine conversion

176 kW (240 hp) / 4000 rpm 470 Nm (lb-ft 347) / 2000 rpm

 

AC Schnitzer o duce la 240 CP: http://tuninghost.ro/bmw-x1-modificat-de-ac-schnitzer-15395

 

Hamman il duce la 249 CP: One class higher, the sDrive20d / xDrive20d can go from the 177 standard ponies to 210 whereas the xDrive23d goes from 203 to 249 horsepower (http://www.bmwcartuning.com/2012/06/hamann-bmw-x1-tuning/ )

 

Si Alpina (in varianta cu 214 CP si tractiune spate)- observati ca e conversie de la e90 320 d single turbo la bi-turbo cu cuplu 450 Nm (http://www.alpina-automobiles.com/en/product-world/model-history/bmw-3-series/bmw-3-series-e90919293/ ):

Si cateva remarci culese de mine inainte de a face aceasta schimbare:

 

"That's quite correct - the torque is always the limiting factor in gearbox designs, as it is this twisting force that will ultimately wear down gearboxes. Where manufacturers give nominal torque ratings for their gearboxes (for instance the 400NM for the GA6HP19Z) these ratings are specified with quite considerable tolerances, to ensure that the gearboxes last for the lifetime of the vehicle. In practice of course, automatic gearboxes do fail, but the failure rate has dramatically decreased with the more modern ZF gearboxes compared to the older designs.

 

The most respected tuners - Hartge, Alpina, Carlsson for Mercs, DMS, Dinan, and others - understand that there are inherent limitations in each model car's specification, and will only tune your car within the limits of the mechanical components. Having a tuned remap producing 500NM in your car whose gearbox is only technically rated to 400NM is not so much of a problem, because the tuners 'torque-limit' the output to ensure that there isn't an excess of twist-action under full engine load.

 

Hartge in particular (I can't speak for the others, other than Alpina but that's a completely different story) warranty their remap and components associated with the remap. So in effect if your gearbox fails BECAUSE of the remap, then Hartge will pay for your new gearbox. However of course that depends on whether it can be proved that the gearbox failed due to the extra torque, or whether it was just a dodgy gearbox in the first place.

 

Both Hartge and DMS have a very good reputation in remapping - not the cheapest, especially in the case of the Hartge, but they have always been consistently reliable, and have historially shown good backup in the odd-occasion when something goes wrong. For instance, DMS' early remap for the 535d showed a problem when the car was being driven in anger around the Nurburgring - on the long straight two-thirds of the way round, two or three cars developed a gearbox malfunction where it shut down and went into limp mode because of excess torque overload... the cars were taken back to DMS, the gearboxes checked over, and the engine remaps modified to be more linear and less aggressive. New DMS-remapped cars have been going round the 'Ring without any problems whatsoever.

 

335 ii biturbo si din fata pana in spate vine cu 2 tevi pe cand 320 are numa 1. Si eu mi-am pus evacuare dubla si am schimbat tot de sub masina cu piese de 335 dar evacuare in sine am facut-o custom.

 

De aceea te intreb ca is curios cum ai facut adaptarea si ce puncte de prindere ai folosit.

 

 

Masina e in service acum si o sa iti fac o poza sub ea ca sa vezi... Sincer nu m-am uitat atent dar m-ai facut curios. Saptamana viitoare cand o iau vedem.

Si discutia despre torque converter de pe Alpina:

 

"

For those holding off replacing their torque converter due to the huge cost from BMW/Alpina (£1000 parts + labours)... then fear not!

 

I stumpled on a very nice chap from ZF called Tom, yes, the people who made our gearbox and torque converter for Alpina.

 

They will happily supply a NEW ALPINA torque converter for £385 + vat + freight (from Germany).

 

They will also remanufacture a unit for £220 + vat + fright, with an £80 surcharge until you return the old unit. If you keep the unit, they'll keep the money, which is handy to reduce turn-around times.

 

He confirmed that internally, new and remanufactured units are IDENTICAL in performance and longevity, so I guess it's only worth buying a new one if something really nasty has happened inside, making it scrap.

 

Anyway, I hope this helps someone...

 

ZF part number for the TC is: 4168 025 383 (I suspect it's for all B3 models)
