Performance Problems

[slidewaysrb25det]

i have searched the forums hi and low and have some conflicting info

Will greedy valve springs for a r34 gtt (8.8mm lift) fit into a rb25det?

Has anyone successfully tried putting n1 water and oil pumps onto a rb25det

Is there any way that i can visually identify a rb25det and the rb20det gearbox? I only have the box not the whole car

does anyone have a pic of a r33 gts25t gearbox? or do they have one out of the car that i can look at???

do they look different to rb20 gearboxes??

Does the series 1 engine have nvcs or vvti like the series 2 engine because i wanna change both exhaust and inlet cam gears

Do 20b rotary injectors fit straight in? i have a aftermarket ecu already

Thanks for any help you guys n gurls can provide:)
