Frequently Asked Questions

Here are our answers to most of our frequently asked questions. If you cannot find an answer to your question, please contact us via email at tech@mazworx.com. Please do not call our sales line for technical questions. Thank you very much.

Q: I see you have the VH to S-Chassis Kit available. Will that work with a VH41 engine?
A: We have not tried fitting the kit with a VH41 engine so we are not sure if it will work or not.

Q: For the VH to S-chassis swap, which starter should I use?
A: We suggest you use the 300zx Z32 starter.

Q: Is there a difference between the Z32 N/A transmission and the Z32 T/T transmission?
A: As far as gear ratios and bellhousings are concerned, there are no differences between those two transmissions. The only difference is in the 1996 Z32 T/T transmission, as that version came with stronger 4th gear synchros.

Q: I see you have a VH45 to S-Chassis Kit available. I want to swap a VH45 into my Z32 (300sx). Will your kit work? If not, will you be making one?
A: The kit will not work in a 300zx chassis. However, the adapter plate for VH to VG transmission will work. At this time, we do not have plans to develop a kit in the near future.

Q: For your VG to (SR/KA/VH) Transmission Adapter Kits, which clutch should I use?
A: You should retain the clutch that is existing on the motor. The VH-VG kit will use a 90-96 300zx turbo clutch and flywheel.

Q: I want to swap a VVL/VE head onto my DET. Which parts are needed?
A: Depending on which DET you are using, we have the complete adapter/changeover kits available.

Q: Why do I keep breaking my rockers in my DET cylinder head?
A: This could be due to several factors. The factory hydraulic setup has very limited power options and does not like being bounced off the rev-limiter or being used on anti-lag. Our best suggestion is to either switch over to a solid pivot setup and do a dual guide conversion or swap over to the VVL cylinder head.

Q: How much power can my stock SR motor handle?
A: This question has so many variables. It all depends on the condition on the motor, tuning etc. Unfortunately, we do not have an exact answer to this but the range is MINIMUM to MAXIMUM.

Q: If I am going to send in my bellhousing in for machining, how do I take the bellhousing apart and what do I send?
A: Please refer to our product instruction section for the removal of bellhousing instructions. All you need to send us is the bellhousing itself.

Q: I have an S13 with an S14 motor. What intercooler do I use?
A: Intercooler setups always follow the corresponding engine, not the chassis.  In this case, the answer would be an intercooler for the S14.

Q: At what horse power level do you recommend using your 1/2" cylinder head studs in a, SR20?
A: We recommend using the 1/2" cylinder head studs for engines producing over 600HP.

Q: How do I degree my cams in?
A: To degree your cams in, you should follow the specificiations based on the manufacturer of the camshafts. For a more detailed information on degree cams and what they do, please follow the provided link. Thanks to Kelford Cams for providing such great information! The Sole Purpose of Degreeing Your Cams

Q: I want to get a lightweight aluminum pulley for my motor. Is that good or bad?
A: We highly recommend that you run the stock pulley or a harmonic dampened pulley (like ATI). The factory crank pulley has a built-in harmonic dampener, in the form of a split design, with a thick rubber pad sandwiched between two steel sheels. The dampener is designed to absorb torsional and vertical vibrations from the crank. Most underdrive crank pulleys do not have a harmonic dampener at all. Torsional vibration is a twisting vibration caused by the pulses of each combustion event. The force of the piston causes the crank to deflect ever so slightly in the direction of the force, and when that force goes away the crank ever so slightly springs back. At certain frequencies the crank can resonate, making the vibration much worse. This is where the harmonic dampener comes into play. The harmonic dampener will absorb most of the vibrations that alot of the motors create especially the ones that turn at higher rpm's.

Q: I am planning on doing a VVL Conversion. What is involved and what do I need?
