Gearbox Bellhousing Machining/Exchange Service
To suit:
180sx, s13, s14, Silvia, 200sx (SR20)
*NOT required for S15*
To successfully install the Z32 Gearbox Conversion Kit for 180sx, s13, s14, Silvia and 200sx's you will need to machine the Z32 gearbox bellhousing. We send you the instructions on what needs to be carried out but if you want a perfect fitting, quality CNC machined bellhousing from the people who designed and engineering the product then look no further...
We have pre-machined Z32 gearbox bellhousings available as an exchange service - send us your old bellhousing and we'll send you a prepared, machined bellhousing (along with the gearbox conversion kit) ready for a quick and easy installation.
If you prefer us to machine your bellhousing (no exchange) we can also do that.

Results/What You Get
Here's some examples of modified bellhousings including chemical cleaning and media blasting:
Conditions of Exchange
Your bellhousing must be...
- THOROUGHLY cleaned inside and outside
- Not have any damage
- Be in good working order
- Packaged safely and securely
- Sent via registered post and insured
If we receive your bellhousing in an unsatisfactory condition we will not supply an exchange, will notify you, and you can elect to pay for it to be shipped back to you un-machined, or wait up to 28 days for it to be machined for an additional $100.
To avoid the above issues we suggest that you send us high-resolution pictures of your thoroughly cleaned bellhousing prior to shipping it to us. Examples of acceptable and unacceptable bellhousings provide for reference.
