7afe engine build, top end Options

[lfk13114]

came from toyotacelicas.com and like noone over there seems to help ne more.

Just to make sure, this is more a question and some help, i hope i am in the right section.

ok i have a 7afe, i have completed everything i've wanted to bottom end. i had it bored from 81 to a 82.5 mm, forged wiseco pistons, pauter rods, rings (9.5:1 comp) high velocity oil pump, bearings ect... i am adding a turbo kit, looking at garret t25bb.

ok with that mentioned, i cant find a single thing to where i can boost my top end. i was looking for cams with longer durations, performance springs, basically the works. so i am wondering, do any other heads fit on the 7afe, whats needed for the modification, machineing, ect.., i heard the 4age fit right on there, but i am still coming up empty handed looking for parts. and its pretty close the 7afe head. i would need all the SAFC and prob E-Manage, wiring harness and all that.


i am wondering if any honda engines like the K series heads might possibly(way out there idea i kno) fit. if not i want something that i can work with and play with.


i have a crap load of money and time into bottom end, i am in desperate need of help and i dont want to ditch it cause its a dead end
if this is posted in the wrong forum i aplogize and please re-direct
please help

so please any ideas, or sites would be much helped

yea it wasnt a problem

now i opted to buy the rods cause i when i get the turbo i wanna push the boost high, like atleast 14psi, i kno the stocks arent going to handle the pressure, thats my main concern, i kno these easily will cause they are the 4340 and a guy in my club has a rx-7 with the 2.2 turbo and bought them and he runs his car at 18 on up psi, so these dont worry me. but when i compared them these were a little bit longer, i didnt have enough sense to measure, so these might bring my stroke up and also my displacement.

i havent used anything on the engine yet, and i prob wont until i can get the head figured, so i case i wanna sell everything or return the parts.

hope that helps

an rx-7 engine does not have rods. its a rotory and they will handle boost better.
longer rods will not increase displacement, it will, however increase COMPRESSION.
piston will have same travel up and down, but moved up, closer to the head.
