If you?re looking to really wake up your 4AGE 20V in your Toyota Corolla, you might want to check out the Kelford Mechanical Camshaft Set 284 284. Kelford?s been in the camshaft game since '68, and they?ve taken their expertise up a notch in the last few years with some slick modern design tools and CNC grinding tech. Trust me, these camshafts are no joke; they?re found in plenty of record-breaking engines across various racing scenes, whether it's the pros or the weekend warriors.
What makes these camshafts stand out? Well, for starters, they?ve got specially designed profiles that really maximize the lobe area on these compact bucket engines. If you?re after mid-lift performance, you?re going to love how they pull in the top end. It?s like unleashing a hidden beast in your ride.
Now, if you want to get the most out of these cams, you?ll definitely want to pair them with Kelford's valve springs. They?ve engineered these springs specifically to match the camshaft, ensuring you get both performance and reliability. For the 20 valve SILVER TOP, you?ll want to grab the KVS51S springs to keep everything running smoothly.
Here?s a bit of the nitty-gritty: these cams operate best in the 4500 to 9000 RPM range. You?re looking at an inlet and exhaust duration of 284? at 0.01mm, which drops to 248? at 1.00mm. The valve lifts are pretty impressive too, with the inlet at 9.35mm and the exhaust at 9.30mm. Plus, the inlet centerline at full lift is 103? and the exhaust is at 105?. It?s all designed to give you that edge on the track.
These cams fit a range of Toyota Corolla models from '85 to '91, including the Fx16, Fx16 GTS, GTS, and Sport GTS. Just a heads up, the picture you see is for illustration purposes; the actual product might look a bit different.
So, if you?re serious about performance and want to take your Corolla to the next level, the Kelford 284 camshaft set is definitely worth considering.
