7afe build, lets see if its worth it Options

[Takumi-FujiWaraS...]

Need to take a bit more off of those divider's and smooth things out a bit more so carbon is less likely to build up, but for the intake side of things relatively rough (Close to cnc smooth) is what you need.

What all is this build going to consist of topend wise?
I would leave a bit of leeway on the bore as you never know what will happen latter down the road, also make sure you can get the piston's and rings first in the size you pick. All good machinest i know require the piston's first before boring to insure the correct fitment and piston to wall clearance of each cylinder and piston.

Sleeve thickness varies greatly on honda block's a b20's is far thinner than a f22.

Good luck man hope to see some tuned numbers when she's finished.

Pistons will be ordered once they grind the crank so i know what bearing size to get, pistons will be measured before boring to match. Dont really have much to port with so doing the best with what i have on hand. Might buy a porting kit to help. No sure on the head. As we all know the only way to go with cams is to grind, web cams charges 600, very expensive. Havent found any over sized valves, dont think id need them. Cant find stiffer springs, not going to raise the redline so probly be ok without.

Look into delta for regrinds i'm sure they will do a set for cheap i've ran their 272's in two of my F22 builds and the cost was under $150 total.

I hand port alot of things i've did a few heads, throttle bodies, and Intake mani's.... one of my latest can be found in my "My Project" thread so just put a bit more work into smoothing things up on the exhaust ports it's worth it. You wont see CNC flow numbers, but my last head flowed pretty good.

Machine shop measured the crank, theyd be able to grind it and knife edge for 400, but id be running .020 over bearings, which is probly not a good idea. So im gunna cut my losses and buy a new crank so i know ill be starting fresh. Anyone ever hear of cleggengine? 7a crank from them is 180 i believe. If anyone has a suggestion of another place please let me know.

Finally finish the exhaust porting. Now time to do the intake. Very very long process. If you have the money. Pay someone to do it haha. I also did some searching. No one makes oversized valves for the 7a but i did come across a compqny sells large amount of oem 7a valves. Odly enough its listed as "1zzfe/7afe oem valve". I cant conform that this means yet another aspect of the 1zz is the same as the 7a. Ill do some more research and hopefully if this is accurate i have hopefully an array of valves to choose from. If anyone can conform 7a valve size please let me know.

I did some measuring of the valves and this is what i found out.
Intake valve:




Numbers read: 87.57x5.95x31.09 for the intake

Exhaust valve:




Numbers rear: 87.99x5.94x24.82 for the exhaust


1zzfe specs i found online:
Intake Valve Specs -- 32.00mm Head Diameter, 5.48mm Stem Diameter, 88.67mm Length
Exhaust Valve Specs -- 27.50mm Head Diameter, 5.46mm Stem Diameter, 88.74mm Length

Havent been doing much with this lately. Last week i started a new job, 8-530 everyday. Havent had time to get anything done. Hoping this will change. Still need to get the crank situation figured out so i can buy the hp kit and rods to complete the bottom end. Then the next task will be to work out the valve situation and finish porting the head. Also need to get the cams sent out to be ground.
But just for those who enjoy pictures with new posts, heres one from my new job. Notice ive installed the 2 1/4in exhaust. Doesnt sound so good so ill be buying a resonator and muffler and some stainless and ill be bugging ben to help me weld it all up. Things i also need to do, 20mm spacers, debadge.

[celica74]

Ordered some stuff last week.


top pic is the magnaflow muffler, and the second is a vibrant resonator. Going full 2in exhaust, afraid any bigger will hinder the motor once completed. dont have a pic of the muffler out of the box but ill get one once its on. i also purchased some items which were long overdue. 2 years ago i hit two deer and the passanger side headlamp tab busted, im pretty sure weve all been there before. sense ben got himself a set of projectors i decided to take his old ones off his hands. all are in great shape
bumper off, crash bar about to come off to get the busted lamps out.

Might as well clean them before installing right?


dont have a pic of the new ones on, storm was coming in so me and ben had to rush to get everything back together.

also something i noticed friday at work. had a ae101 i believe(not familiar with corollas chassis codes but a 97 4 door with the 7a) come in for a ps pump, high pressure line, and other things needed to be done. I took a good look at it and noticed something. see if you can spot the difference

if you havent noticed, look at the intake manifold. Notice how the lower left side corner is cut away. unsure if its because of the newer year or if its a corolla thing. i thought it was interesting and wanted too see if anyone had some insight on this.

I can't tell the difference just by looking at that pic, but I wouldn't be surprised if it's a post 95 thing. You'll also notice they changed the alternator bracket to a slightly different black one and no longer tapped the oil cooler return in the top oil pan. I'm not sure if it all changed in 96, but it makes sense.

[Box]

It's a year thing. 94-95 ST had 110hp, where as the 96-97 ST had 105hp.

[celica74]

makes sense. guessing these changes were due to obd2 emissions requirements.

[Box]

Yep, that'd be it. Stupid OBDII.

i couldnt agree more haha

Oh well. Personally I prefer cars without any computers.

op where are u located in nc? this looks ALOT like my old st do u remember a name or anything from who u got it from? im positive it wasnt from me but im thinking maybe i was a few owners back. the last time i owned it was in 2007 if it is the same car. idk if i have any old pics or not.ill look. if its not the same car then oh well, nice looking car anyways and im def subscribed to see i high compression build.

ive had it for 3 years now, i live in cary, just outside of raleigh. bought it from a guy in louisburg. apparently im the 6th owner. i know the guy sold it cuz he just bought a 7th gen. cant remember his name, he seemed in the early to mid 20's though.

[celica74]

HP kit has been ordered. Gunna be 3 long grueling weeks till they arrive. Pistons have to be made. Also ordered some other goodies. Shall i spoil or keep the anticipation?

[bsamps4]

I could make you some pistons!!! They would be Cambells brand!

[al94st]

What compression ratio?

[celica74]

Ben. I dont think the tomato soup ones would hold up. Think id have to go with the chicken noodle

Aj. Whats the fun in saying? Surprise! Btw check your messages
