Could anyboy help me out?
I have got to learn alot from this topic but I am really confused right now...
Actually only thing I need to know is... What do I need to put in a 6 spd gearbox on an engine that has automatic transmission.
I have a Spec S, buying a Spec R engine with automatic transmission and I want to fit the 6 spd gearbox.

clutch pedal and assembly, clutch master, clutch slave & line, 6speed specific flywheel and specific bolts, clutch itself, S15 Spec R drive shaft.

Since you have the spec s, can i recommend you just use the 5speed box, as you will find them cheaper and easier to come by any S14 5speed will work as its the same box as the spec s manual

Is your car manual now or auto? Forgot to ask that I assumed your car was manual just the engine you had bought was auto.
5 speed box would just need clutch.flywheel and bolts plenty of people have done it so is info on the site and is much much cheaper than the 6 speed. Can pick the s14 boxes up for £150 odd .Will also need the gaiter for your centre console if the car is auto atm

The bolts from box to engine can be used but I believe you have to use different flywheel bolts for the 5 speed . Have a look at the start of this thread there is links for whats needed to fit the 5 speed

Hi everyone,

Newbie here looking for help. I am a S15 Spec R Auto owner.

May i know how much horsepower of this automatic transmission can withstand?

Is the Spec R Auto Transmission same as Spec S Auto Transmission?

Thank you.
