Setahu saya sih cuman ganti piston dan stang piston nya bawaan 3GR-FSE aja deh . . .
Tapi mungkin mesti pakai block engine nya 3GR-FSE. Kalo liat di luar bisa dipasang supercharger tuh . . .
Thank you for your reply!
I thought so too actually and maybe you are correct, sepertian musti pake engine block 3GR-FSE ya.. yg pasti kalau pake block 3GR-FSE pasti gawean lebih efficient (lebih cepet) tapi apa bisa di re-bore kah block 4GR-FSE? Atau terlalu risky? Sorry pertanyaan basic tapi saya mau pastiin sepasti pastinya sebelum melangkah karena menurut kesimpulan saya, yg mungkin bisa salah, 4GR-FSE itu seperti de-tuned 3GR-FSE
Nah kalau ganti block apa musti reprint ulang kah engine numbers'nya di new block?
Sepengetahuan saya kalau stroke up, yg pasti musti ganti: cylinder heads, piston rings, crank, seats and all other associated parts. Tinggal block nya nih apa perlu diganti or yg sekarang re-bore aja?
Kalo supercharger 4GR-FSE jg bisa tapi not as common as 3GR-FSE supercharge karena Modellista pake base nya di 3GR-FSE karena better torque profile vs. 4GR-FSE , HKS supercharger pake based 2GR-FSE (3.5L more advance engine) tapi ini a different discussion for a different time and topic..
Another info penting yg saya udah found out, info di Lexus Euro forum, untuk Lexus is250 2nd gen alias 2is250, swap from 4GR-FSE ke 3GR-FSE ECU nya bisa pake 4GR-FSE and semua tinggal plek langsung nyala tapi harus tuning karena AFR read out nya too lean di atas 6000rpm persis seperti 4GR-FSE di supercharged. By the way, ECU saya udah remap tinggal remap lagi to accommodate 3GR-FSE. Hasil remap hasilnya luar biasa banyak restricted power yg bisa keluarin yg musti dibarengin combo Intake/Header/Exhaust (IHE) buat maximum gain
Kalau di forum China, mereka ganti sekalian sama ECU 3GR-FSE tapi ini di mark x GRX120 alias generation sebelumnya. GRX130 ECU nya lebih advance..
Yg lain please bantu input'nya jg ya.. thank you
