RB26 Valve Train Upgrade - Need Suggestions

[etang789]

I am doing an engine rebuild soon, most likely with Nitto 2.8 Stroker Kit with EFR 8374 1.05ar; and I need some advice on which valve train parts to select.

 

I want to have a quick response engine, and thinking to go with:

Tomei PROCAM RB26DETT IN 260 10.80mm cams

Ferrea Dual Valve Springs & Titanium Retainers

 

What about:

Oversize Valves ??

Valve Guides ??

Don't use Tomei cams. The ramp rates on them are weak and is why you see so many people complain about lag afterwards. 

Talk to Kelford for Cams. 

If you have the head apart do guides (OEM/Supertech) stem seals (supertech) and give it a mild port while you're there. 

Dual springs and TI retainers not needed unless you pl[an on revving it much harder, simple spring upgrade and stock retainers will suffice, but Ti retainers will lighten the valve train and make it rev nicer, single spring is enough here and keeps total mass lower. 

Bigger valves aren't "needed" and will add some decent machining cost etc, but it will make the whole show more efficient. I'd say not needed for 8374 personally, but talk to Kelford and tell them your plans/full setup and work from there.
