Modified Corolla 1600 16v 4AF Carb Engine

Good day

I am new to this site but after reading a few post i decide to join Toyota Nation.I own a Corolla 92 model 1600 16v 4AF with carburetor. After overheating problems i had the engine done completely. New pistons 20 oversize, free flow exhaust(standard) K&N air filter ext. One problem is after the engine overhaul my compression sky rocket (13.5 - 14 bar per cylinder) with a few problems. Since then i had a very big problem with pinging so bad that i had to change spark plugs to a racing plug, i use a octane booster in the petrol to boost it to 104 octane petrol and i change my cam pulley to a vernier cam pulley. After all that changes the pinging was under control. It goes very nice and get to top speed very quickly but use a lot of juice. I decided to put on some modified 276 cams and take it for a complete dyno after that. Can some of you people maybe give me some more info and also what do you think of the cams. Thanks a lot

wow.. where are you getting cams for the 4afe from? id love to get a set of them too, and do bolt ons like intaks headers and exhaust with some cams and get a nice tune for 91. but nice on the compression, i dont want to run boost so i kinda want NA but not any crazy swaps.. some reason im attached to this motor.

There are not very much available for the 4af engine. As for the cams i understand that you take the 7 afe Cams with bigger lobes and then you will need to regrind that to what size you want.

OIC! so your just taking some 7afe cams and grinding them... that sounds like a lotta work... im not a machinist so i wouldnt know where to start on that.... itd like to have a better lobe... where are you getting yours done at? i dont understand the world of cams yet...
