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.

the crank is my biggest problem there are no after market ones so im going to have to make do with the 7afe crank with treatment etc .

82mm would be nice but i might stay 81mm dont know at this stage

pistons i wanted to go 8.5:1 but 8.0:1 is safer what do you think?

ARP head studs for 4age ordered still need more hardware

exhaust an head will be metal hk$ or trd

hks manifold is 250 shipped on a few sites still talking with froutou about a custom one like his.

turbo will be a T3 super 60 or t3 t4

the manifold thing Kwanza sent me a small port not knowing i wanted a big port just a little miss communcation.But im not sure what to do ive see the DIY manifolds on ebay or getting a big port manifold from kwanza??

i already have a intercooler lined up that supports 500 horse and its big

pm me some info on the water sprayier system if you would and will chat

well the clutch still trying to figure out what i want

injectors i have some 440 but i need to upgrade into 550cc+

for this project diffent 3 inch exhaust but thats last on the list

that remote exhaust system is trick but spendy maybe later down the road

pm me some info on your autometer and well talk
