Hey all,
I am currently building up my 7afe, i have bought a separate head and have already had new valve guides installed, its been cleaned and i have brand new toyota valves, exhaust and intake, i have had the intake ones machined to have more of the performance "penny on a stick" figure, i will post pics soon but for now here is an example Valves. I am also going to have the Extrude Hone process ( Extrude Hone ) done to the entire head. The current 7afe in my car has a custom 4-1 headers (Headers), full exhaust, intake, clutch, lightweight flywheel, Apexi S-AFC II, bumped timing to about 14 degrees static timing. If i can find a used GT throttle body i will try to make it work, they seem to be fairly similar. Its been tuned and it has over 225k miles on the original engine. The gear box has been rebuild to brand new, and at last dyno the car was putting just about exactly 100 WHP on a 95 F day. So i figure its already a healthy working little motor. To make this short, i was wondering who has had the highest NA horsepower out of a 7-afe . I am hoping to be able to build my motor to about 120-130 WHP, that would be ideal but im not sure exactly if i will achieve that goal. The bottom end is going to get first O.S. pistons, the head will be decked for a slightly higher compression ratio, and the entire engine will be blue printed. Then the entire crank assembly will be dynamically balanced with the flywheel and all the accessories on either end of it. Then it will all be put back together and have another tuning session on the dyno. Now i know that it seems like a lot of money to do everything i am, which it is for only 130 WHP, but im looking to make this a great motor for auto-x. And if i have 200 WHP then ill just create a smoke show, so thats why im not just swapping in something else. **CLIFF NOTES** Who has the highest NA power 7afe with dyno numbers to prove it? ![]() This post has been edited by 94celicadude: May 9, 2008 - 5:27 PM -------------------- ![]() 1994 GT Hatchback 1994 ST Coupe 1988 Corolla Wagon All-Trac 1999 Corvette 2008 Cobalt SS Turbo |

well, i had to stay only with the first oversize pistons because the class i run in auto-x allows for only the first over size. Thats the main reason that the CR is stayin close to that, and for cams, i do not yet know but i think that im going to try to get a set of cams reground and possibly play with that for more power, but for the moment i am staying with stock cams.
