Are these valves compatible with alcohol-based fuels?

Yes, these exhaust valves are specifically recommended for use in alcohol engines. Their robust construction helps them perform reliably even under the conditions associated with alcohol fuel use.

What is the difference between Race Master and Race Flo valves?

About this part

Product Details

If you're rebuilding the top end of your 1989-1998 Nissan 240SX, especially for racing applications, you'll want to consider these Manley Race Series exhaust valves. These are built to handle the stress of engines running up to 8000 RPM, making them a solid choice for bracket, drag, or oval track use.

Manley makes these valves from a strong stainless steel, which is crucial for exhaust components that deal with high heat. They've also added chrome stems and hard tips to help them last longer and resist wear, especially important if you're running alcohol fuels, as they're recommended for that. The swirl-polished under-head area and fully machined faces are designed to help air move more freely, which can improve how efficiently your engine burns fuel.

These are the Race Master style, which means they have a straight stem. Make sure these are the right size for your SR20DE or SR20DET engine build; this specific valve measures 30.15mm.
