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.

hey Fallen

i think 250 whp is a streetable application
but now are you talking about the motor or power out put?
the 3sgte guys are running around close to 220 -250 whp
my turbo 7afe is only 170whp and 180 trq with better injectors it can push in the 200 and still be streetable

stock blocked... it would be what... 12ish psi maybe 14 for 200+whp? (we are talking 7afe)

Ok. Yes, that is perfectly streetable. I just don't think it will last. the 7afe is classically unreliable when it comest to boost. Granted, most of the 7a problems can be accredited to high miles, shortcut somewhere, missing the signs, and then the engine dies.

I don't know anybody that has run the 7a for an extened period of time on boost and not had to re-build. how long have you had yours running?

The engines actual running is not the problem, but reliability... i just don't like it. If your power goals were at 200whp with a 7ag, I would say that is a good shot. there you can build the engine right, with the right cams, 82mm forged pistons, prepared rods, etc and have Safe and reliable 7a at 200whp.

I think 250+is pushing it. All I can say is prove me wrong. I would not be angry or sorry in the least if I was. Matter of fact, I'd be a bit proud.

Like I said, I am not being an ass, I am just saying the 7a isn't worth the trouble in my opionion.

Good luck mang. Don't cut corners.
