7afe build, lets see if its worth it Options

[celica74]

So a little history. Have had my 94 st for over three years now. Has had two motors in it. Stock one was neglected so i replaced it with a 95 with half the miles. All the car has done to it is the basics. Short ram intake, exhaust with ebay header, dropped 4 inchs on drop zones(cheap rout i know but im happy with them. Voxx 7.5 rims running 205/40-17s. I love thos car. Cant believe i almost got rid of it for a genesis coupe. Havent done anything to the car in the past year because i bought a bike. But now im back in the car game and ready to spice her up. Have considered many options on what i could do to make then realiable eco friendly cheap slower then a single cam civic motor some pep. Yes ive gone over the 3sgte and 3sge swaps. Honestly there not for me. I almost turbos my car 2 years ago but lacked funds and patience. So the other day i took a drive up to virgia to visit a fellow 6gc owner(or have a one. Hes parting his car). I pics up some goodies from him for a good price. Dont wanna spoil anything. Pics will be up soon on what i got and what my intentions are.

Been hard at work. Like ive mentioned before, im dead set on an n/a build. Did alot of searching and no one that i can find has done anything to the 7a really besides turbo. Hoping this thread will encourage more members with 7a's to not just swap, or turbo, or just leave stock, but to have some fun with it, spend some money and make a screamer. My goal is to outrun a integra gsr. They weight about a hundred or so more pounds then a 6gc, and make about 180 at the crank. So if i can get anywhere from 155 and up hp at the wheels my goal should be achieved. I took the crank and main caps to the machine shop today, getting a quote on knifeedging the crank if the guy there will actually do it. Also took some measurements on the block and determined that i can not only bore .040 over. guess what. I can go more. Block will be bored out .060, leaving about .250 for the cylinder wall. Machinist said some of the honda guys run turbos on cylinder walls less then that, so this should work out quite well. Surprised the 7a have that much meat to it. So with .060 over the 7a will be a 1.95l according to other people who have board only .020 and .040 over before. Gunna order the pistons and rods and rebuild kit probly next week. Pistons specs 82.5mm with 11:1-11.5:1 comp. Alright enough with the technical drowsy eye crap. heres some pictures.

Two pics i took out in fuquay the other night with my friend whos got the only zx2 four door escort.



Didnt get any pics of his car. His escort outran two different gsr's at the strip a couple weeks ago and will be a good benchmark to shoot for.

Started porting the head today. I started on the exhaust thinking if they were off a little bit due to this being my first time porting it wouldnt matter as much as the intake. I used some sanding bits on a drimel and a drill. I also have a metal burr remover, nasty sharp sucker takes the metal away like its nothing, making the initial removal easy.
First port as using the burr remover

Allowed me to open the port right up fairly quick. After that i just used the sanding bits to get everything flowing and opened up in the tighter spots.
This is port one finished

Couple people have said that its better to leave the intake ports a little rough to help create turbulence mixing up the air and fuel, but i figured itd be better to smooth the exhaust out as much as possible to help it flow better. So i used 120 grit sanding wheels and made sure everything was nice and smooth.
Finished up two ports today, heres a look at them.
