you went straight from aeronautical engineer to heart breaker.. i believe youve been told what im doing. fully built na 7a. read a thread on toyo nation of a 4afe powered dune buggy making 248whp na. the only thing holding it back is the head. look at the valve angels compared to f1 heads. very similar. Open them up and smooth the hot spots to make it flow, especially on the exhaust side #1 and #4. exhaust valves need to be atleast 1mm bigger with a back cut and radius job. throw some bigger lift and longer duration cams, no reason it shouldnt make 250 when blown. also read some 7age builds that are reving 9k with only arp studs on the rods. yes i agree its costly because for the same price youll have a freshly rebuilt 3s with a fmic and other bolt ons. but then again you could probably go through this forum and find 50 alone. find me one fully built na 7a or 7afze. dont get me wrong ill do a 3s in the future, but i think itd be more entertaining to have the pile of sh** we know as the 7a actually make some decent numbers. btw how much would you sell the sc setup for?

Don't get me wrong, I'm not saying it can't be done at all. 7ag(t or z)e can make a lot of power. I just don't think it's worth it. For you Alex, cheap. I'll pm a #.

^ Okay, f*ck this guy, but I'm curious what happened with the kit...ever get sold?

i actually never responded aj. i apologize. i appreciate the terms we agreed on and everything, but i wanna keep the 7a na and prove power can come out of it.

Cool, that's always a good goal. There aren't many people that go that route.

That's cool Alex. Ferdi, it's still on my car, until I decide what I want to do next.

^ Keep it there. I'd take it off your hands but I've got another project & priority.

1MZ-FE swap, plus the supercharger. Just saying.

the people that do only do part of a build. most just get a 11:1 comp and leave it, getting 110-120 to the wheels. ive seen others porting, no one posted the result though. stef put cams in hers before she turboed it, it was only a 220 set, but more power was noticed throughout the rpms. im doing top to bottom. everathang.

...end of story. For the next Chapter see This Thread. Have fun Alex.

Hi,

On the top of the cam cover on the 7AFE there are 2 pipes that go to/from the plenum chamber. I notice that the smaller pipe on your plenum goes toward the intake pipe and disappears but i'm guessing goes onto the BOV and the larger pipe on your cam cover goes to your oil catch can.

However, I'm wondering what you have connected the smaller pipe from the cam cover too and the larger pipe on the plenum too as I couldn't see them to trace.

I'm looking at Supercharging my 7AFE lump so will be using your thread quite a bit for guidance.

Thanks

Rob

On the valve (cam) cover: Large hole (pcv valve) was plumbed to the catch can. Smaller port (which went to intake manifold) was blocked off.

On the intake manifold: Large port (pcv valve) was plumbed to my boost gauge. Smaller port (which went to valve cover) was connected to my blow off valve.

You cant block that small hole on the valve cover!!! No wonder you blow your headgasket! I made an ITB setup on the 7afe did the same thing and blew the valve cover gasket and rings!

o_o you blocked a breather port on the valve cover?
