Needed input, 7age vs 1mzfe Options

[Einhander]

Ok, over the past few months i've been gathering parts for a 1mzfe swap. I finally have everything But the ecu, but that's not a big deal. I know the motor will fit, that's not the issue. And i don't want to make huge power 280-300hp at the most.

But here's the delima, i have everything for the 4age head converison. I would like eventually to go turbo and the 1m is not going to leave a lot of room for this, unless i go crazy on the engine bay, and piping will be a pita. Plus the turbo 7age has already been done and has sources for reliabilty, where as the 1m really is not a heavily document motor as to it's abilities.

Now my question to you guys is if given a choice, with a goal of 300hp which would you choose?


this is something i am going to complete over time, since the celica is no longer a dd, and i work almost continously, hopefully by late summer it'll be done.

people have been throwing around that link for years now. I would love to know how long it actually lasted at those boost levels.

You are not going to have a good easily streetable, reliable 250-300whp 7afe... or 7ag for that matter.

It'll run at 250whp for a while... it will be peeky and a pain to run in traffic. and after a year or two will need new rings... or worse.

I am sorry if I sound like a pessimist, but the 7afe is a boat anchor.

Yea, you can bore it, put in new pistons and rods, G head fully built with turbo... spend 4-5 grang in machine and parts... or you can start with a proper platform and be happy. Like me I love my car, but it's not a sports car. It's a DD, and that is the role it is going to fill for me.
