More New product launch's from Tuning Developments, we have been working for over 18months on a new range of valve train products to fit the SR20DET Black Top VVT Engines, and after testing these products for so long, they are now available.

Tuning Developments Performance Valve Spring Kits use a single spring setup with the optimum base spring pressure to suit the SR20 Cylinder Head, they have been custom developed for Tuning Developments ONLY and are one of the best drop in valve spring sets on the market today.

Standard valve springs are common to show signs of valve bounce/weakness once running above standard rev limit when running bigger turbocharger setups with high boost pressures or when running high RPMs consistantly, we strongly recommend these Performance Uprated Valve Spring Kits for anyone building a Forged Engine or looking to have one built as these ensure perfect performance no matter what RPM the engine is running. Must have upgrade for any drift car to maintain optimum reliability.

100% direct fitment onto a Standard SR20DET VVT Black Top Cylinder Head, Also a perfect combination with Performance Camshaft Kits, we strongly advise a experienced engine builder install these products and all required measurements should be checked prior to complete install, if your unsure or would require fitting please contact us for further details and pricing.
