RB25 Auto to Manual conversion question

[atermizi]

hi guys,
i did a conversion from automatic to manual gearbox...bt here's the issue the speedometer is showing the wrong speed (faster than actual). Im still using auto ECU and auto speed cluster. so when im on 60 kmh its showing 180 kmh and suddenly the speed cut off plays in.

How much would it cost to do and GTT to GTR widebody converstion ( i swear i WILL NOT slap a GTR badge hehe)

thnaks in advance

are u in US?
i had a r33 auto rb25 before.... was thinking to do what u did....

but in the end not worth it bro...

might as well go for a gtr....nowadays they're not hard to buy (except for r34s )

I can't remember the exact thing, but if I remember well, it is your speed sensor at the gearbox. If not mistaken, even the position of that speed sensor is different on auto and manual as well.

Well update here again if im free.

guess what guys so today i went to Dazzle motosport in Puchong..the Izzat the owner told me that the previous mechanic installed the wrong gearbox it is an Rb20 gearbox. And the speed sensor is for SR20. Anyways the conversion was done by previous owner. so i guess i need to find an Rb25 geabox laying around somewhere.
