7afe Turbo Options

[Cevax]

Well I didn't want to start this thread yet since I am still sourcing parts but I really need help getting parts since I am not sure what to buy. I have a 7afe now but i believe it has a rod knock and was told by a mechanic that to change the piston and rods the whole block has to be machined and will cost too much money, even though its only 350 dollars on parts or so for OEM pistons rods and rings he recommended me finding a new engine which I cannot find for less than 750 including shipping.

but if I buy piston and rods why wont they just drop right in?

I also have a 4age blue top head in my house that I got for the build before I found out my engine might be blown but if I have to buy a new engine its going to cost way to much to even begin the 7age conversion. My engine has a constant "knocking sound" coming from the cylinder head at around 1500 rpm it goes away at high rpm, It has 155k, abused but still runs strong. But during all this time looking for a motor (and saw a 7age with 115hp) personally started thinking that going with just the 7afte idea might more cost effective and since the 7a gets to peak torque so quick it should be more fun to drive( thoughts please), but anyway anybody with any experience on building a motor does it really have to be completely machined.

thanks

I am just going to copy and paste what I put in the other forums

"Bad news, lol it it blew up before the turbo LOL, I was driving down the road playen around and it just shut off, stopped and smoke everywhere opened the hood and took like four minutes for the smoke to die down so i can see, and fluid everywhere but couldn't take a good look. Engine turned on like nothing happend and turned around and it ran fine but then it started losing power.

Now I could have stopped and just waited and called a tow but where I was at and no batteries on my phone that was not an option. The engine just shut off again and when i hit the ignition it showed temp at maximum stayed for a bit and viola engine turned back on. Drove it back to a gas station because where I broke down their where no street lights, at the gas station I could see what was going on. The power steering pump fluid cap blew off , HOW I HAVE NO IDEA and fluid everywhere, pulled out the plugs and one was wet, but it looks like it entered through the plug wires.

Radiator reservoir was empty, now I added fluid and hoped I could drive it back home but when it was moving after a few minutes I could hear something beginning to grind or rattle, it was a very mechanical noise but I just kept trying to keep it running because there where no emergency lanes and couldn't stop and then it finally died i was moving at sixty and coasted until a gas station pulled in and there was a tow truck that looked like it was ready to leave. Got a tow back and never turned back on, just a really bad smell when you try to crank it.

And its over before it started, now I love my rolla but the 7a just isn't the proper motor now I don't really know what to do. Risk it and get another motor and just go all out and get a 3s or 5s or just bite the bullet and buy a new car. hmm decision decisions"

Hey crap happens, It looks like the water pump blew and it was a brand new water pump at that too but since I drove it in that condition the engine didn't make it. At 27 miles from home on a highway with no street lights I wasn't about to stay there. It could have also been a clogged radiator maybe, even though I had it flushed before the new motor. Well good thing it happened before the turbo other wise it would have been a disaster after. I will figure out what to do in the next couple days, to rebuild, swap or buy a more potent car.

Getting a more potent car, selling the thing for 1200 with everything if nobody bites there also a part out, not going to post here since its not a 6g but its on corollacarclub
