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

Well I took the time today to take a closer look at the motor, the sound is definitely coming from the top end. I have no idea what it is, could be a tensioner for all I know but it looks like there is rust in the radiator and most likely there will be rust in the motor too, oil is clean though no coolant in it.

I considered the 3sgte but I have been to hell and back when it comes to ordering engines, I tried the 20valve route and was screwed and that is why I am trying to avoid the engine replacement route. I did find this on eBay though

see that "looks" like a good deal before shipping but I am sure shipping will probably cost more than the block. But since this is my only car having a motor remain in the car can really help me a lot.
