6boost Exhaust Manifold – Nissan RB25/30

Description

6boost RB25/30 Exhaust Manifold 

Suits: RB30 block with RB25 cylinder head engines (RB25/30 engines) – DOHC

6boost manifolds are the absolute go-to for upgrading a custom RB engine, including the RB25/30 combination. With a taller block on the RB30, the RB25/30 combination positions the turbo higher when using a standard RB25 exhaust manifold. For larger frame turbos and other custom configurations, this can lead to clearance issues with the turbo sitting too high. Hence, the 6boost RB25/30 turbo Manifold which counteracts the height increase from the RB30 BY lowering the turbo position.

The 6boost RB25/30 Exhaust Manifold is available in different turbo flange options including T3, T4 V-Band, Forward Position (FPPM) and T6 Forward Position as well as open or divided and a range of wastegate configurations – 6boost offer a complete range for the platform!

V-Band vs Forward Position V-Band: 

The 6boost RB25/30 manifold offers two varieties of v-band flanges, the standard V-Band and the Forward Position Pro Mod (FPPM). The standard V-Band sits the turbo at a more centered position against the engine and is recommended for turbos 80mm and smaller. The Forward Position V-Band is designed to sit the turbo further forward in the engine bay for larger frame turbos that require extra clearance on the front compressor housing and are often used for 88mm+ turbos.

To understand the RB25/30 turbo manifolds combinations available from the drop down, see a break down example below:

T3/45: This combination uses a T3 turbo flange with 45mm single wastegate port 
T3/2×40: This combination uses a T3 turbo flange with two 40mm wastegate ports 

Why choose a 6boost Exhaust Manifold?

At SRS, we put a 6boost on every build possible and there is a good reason for the hype! When measured against the rest of the market, 6boost stands out with:

• Unique exhaust gas flow design for maximum turbo performance
• Robust against high temperatures – we regularly see 800°C+ EGT’s with no issue
• Designed with the strength for bigger frame turbos – we generally don’t brace our turbos up to the G45
• Hand fabricated offering improved sound over moulded options from other brands
• Local, Australian owned business guaranteed by a lifetime, unlimited KM warranty on all manufacturing defects and failures

Weaker manifold options are prone to cracking from heat or under the weight of larger frame turbos. 6boost cuts these issues from the picture, offering a long-lasting, strong exhaust manifold upgrade that stands the test of time.
