Customer Questions
Question:
Hi there, Just to confirm I Own a 1991 JDM import RHD Nissan Z32 Slick Top with a Stock VG30DETT Engine with EGR removed and I would like to purchase these Stage 1 Heads Refresh! My Question is this are there any difference between the JDM and the American Domestic Market VG30DETT engines including these heads you supply or will these fit?
- Lance
Answer:
Hi Lance, there is no difference between USDM and JDM cylinder heads, you'll be good to go
Question:
What if I don’t know what year the motor is?
- Aaron
Answer:
Hey Aaron, you can identify the heads by looking at the casting markings on them.
30P = 90-92 NA
10Y = 93+ NA
40P = 90-94 TT
48P = 95+ TT
Question:
On the “Pitstop Stage 1 Head Refresh, VG30 - Nissan 300ZX 90-96 Z32” can I get my current heads to match the TT heads? I have heads from a N/A motor that I am planning to build to a TT motor out of this N/A block
Answer:
Your cores would need to match what you're getting back, so if you're sending in NA cores, they would only be able to build your NA heads.
