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.

Aha...

With a goal of 250whp, it's gonna be the 1mz.... much more so when thinking 300.

The 7a... god love it... will never find reliability in the 250ish range... The 1mz... 250whp is a tuned with mild bolt ons. AND a reliable daily driver with a torque curve so flat your mamma could sit on it! honestly man, the thing makes max torque at like... 1800 RPM's or something and then stays constant all the way to red line.

And why turbo it? TRD makes a supercharger that could put it up to about 300 no problem. Look at the MR2 that won the sport compact challenge. It's a great engine,,, and with V6 power. In ANY situation it would crush the 7ag. It's up there in 3s territory.

And yea... I did TONS of research into this swap.
