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.

Well, that is true. The 7ag will be MUCH less work. however, If you are looking for 300whp, the 7ag just won't do it. Turboed, the 7ag can produce a reliable 200whp in my opinion. NA it might make 160 at the wheels. Any more than that and you are un drivable for daily use. You might be able to squeak a bit more in the TURBo form, but you will be limiting the life of the engine.

there is only so much you can do with 1.8ltrs of old tech reliably...

the 1mz came in the toyota camry, solara, one of the vans I think (sienna) and the Lexus ES300. The Solara was the only manual model.

7agte can hit 300 horse as for the reliablity well thats all on how its tuned (correct me if i wrong) if its tune right you can run around on 250+ horse but then it comes down to FWD usable power which i dont really care about 300+ even 500 + on a fwd is usable then you're driving just not so much at a stop ((traction))

in a celica both engines are rare but 7agte is the easier install IMAO

i might be bias (SP) but i'm headed down the 7agte path so.....
