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.

truth, a dyno would have been great.

I'd have my crank crayo treated. I hear it greatly improves te strength of heavy wear rotating parts. I would also think about having the rods pistons and bearings treated.

For big boost I would also step up the 82mm pistons.

250+ hp with 8-1 compression means LOTS of boost. That is no problem with good pistons and rods... I would definitly look into your options as to the crank though. New studs all over the block also are important.(mostly head studs) and don't skimp on a cheaper head gasket. For Serious boost and high power aplications I would go HKS or TRD or somehting made for the power. Copper... I would dodge. It might work, but I would rather know I didn't buy the cheapest. The same goes for the exhaust manifold. i don't really know which you are going to use, However: HKS does make a manifold for the 4ag. I think it supports a T-25 or something... I am sure it can be made to hold a T-3 hybrid... or you can get a custom equal length from somewhere.

If you go largeport head I would try and build a custom largeport intake manifold. Instead of eight runners I would use four huge really short runners with a large TB. Not to mention a BIG Honkin intercooler. This is another place that you cannot afford to skimp. When running high boost I would have a water sprayer that woudl kick in at given RPM's. you should PM me and I will help you build one. I have all these good ideas you know.

hrm... evil clutch also needed... Monsta injectors... what size are you going to use?

I would have a regular exhaust system (3ish inch) with proper resonators and muffler for regular driving, but I would install a remote exhaust bypass valve for high horsepower high boost levels.

Also I would MOST CERTAINLY invest in a wideband O2 sensor.

I have a really nice Autometer dual imput temperature sensor set up I can sell you if you want it. They are like $300 new. I'd let you have it for $100 shipped or something. They (two of them:dual imput) read up to 400. Most people use them to guage intake temp. I was going to use it as a intake and piro meter though.

Anything I can help you with man, just let me know.
