After reading the big topic on celica.net Im almost convinced on the supercharged 5s. "Go with the 3s blah blah blah". NO, anywho the rippmods sounds pretty awesome. Unlike the fabled 3s.. you get all NEW parts and direct plug and play. So if your even contemplating the do a swap reply, in your upper left hand hand corner of your screen is a "Back" button go ahead an press it. SC 5sfe at 190whp out of a box is pretty awesome.

The 7a isn't that bad,it's not heavy, and not near as weak as people say.

" Engine Block:  7A-FE fitted with oil cooled pistons
Cylinder Head: 4A-GE 20valve head
Pistons:  4A-GZE pistons
Connecting rods:  ARGO custom rods with 3/8" ARP bolts
Crankshaft:  Standard 7A-FE
Compression Ratio:  8.9:1
Boost pressure:  18psi
Power:  300hp @ 7000 rpm
Turbocharger:  Garrett GT25 twin ball bearing, 320hp model
Intercooler:  Water-to-air "

This is a far off example, but an example none the less.  I put this up to show that a 7a crank can handle 200+hp.  I have e-mailed the guy that did it to find out how long it lasted. (hopefully still on the road.)
Now: a 7a with 4agze pistons and custom rods could be had for about a grand I would think.  Then throw in the turbocharger and you could have boost around 12-14 and no problems.(properly intercooled.) 

That's not bad for power or money, as long as you were only looking for about 250 hp.

Don't agree so whole heartedly on that website's ideas.

First off, you can't use gze pistons with the 20v head. Custom forged rods range between 500 (cheap) and 1000 easily. Even with just the 7AGTE set-up, as planned (minus the 20v head cause that's kinda impossible with gze pistons) you still can't safely boost that high because of the crank. You've yet to mention what can be done to the crank... and typically, a custon foged crank can mean $$$. Then again, the stock crank can probably take 10 psi fairly reliably. Beyond that, you're pushing your luck. The hybrid build, with the GE head on the 7A block will mean custom ECU and fuel maps, and possibly electrical and sensor work. After all of that, you'll still need a custom turbo kit, IC piping, oil lines, tuning, and so on and so forth. The normal build (gze pistons in 7AFE motor) will only need custom rods... so I'll say that set-up shouldn't be too difficult.

I'll ask now FallenHero... not to bash the 7AFE, or you, but can you do this sort of custom work alone? I for one can handle everything mechanical and most of the electrical, minus the custom ecu, fuel map reprogramming and such, custom machining, etc. Even I, would not try this mod because of all of the obstacles that it comes with. I drive my car on a daily basis (as do probably 90% of the people here), and cannot afford, nor have the time to plan something like this. I'm sure a very dedicated mechanical engineer or shop guy can muster out a project like this, or something similar, however, simply turbo charging the 7AFE as is, will put similar power results with less than 1/10 of the headache.

Hybrid build... I would estimate can cost around 4k+ (including custom turbo kit) with self-labor. With shop labor, even more.

Turboing the 7AFE can cost around 1-2+ grand self-built.
