Progress thread: 3VZ-F(T)E V6 Swap into my 94 GT, The V6 RUNS! Options

[stephen_lee]

I've been talkin about a 3VZ swap for quite some time now (~3yrs).
I found a fairly decent, non-running, 94 GT last july for $300. Beautiful interior and everything, only a dent in the drivers door, and a broken bumper (which i have a few spares..)
Soo I picked up a manual 92 ES300 a few months ago as a donor car for my swap
I've been driving it and good god the motor is a beast. the torque is there 100% of the time - even at 2000 rpm. The intake sounds like a pissed off Porsche. After feeling a 3s swap(DEATH) and driving the lex, i think it should produce about the same results, if not better, stock for stock. now adding the turbo should up my power even more considerably since i have 50% more displacement over the 3s. This motor redlines at 6600 and fuel cuts at 7200rpm, but falls on its face around 5600-5800RPM - comparable to the 7a. I'm thinking a good turbo will alleviate that problem i washed the engine recently and somehow killed the AFM so when i swap I'm going megasquirt EMS will reduce a lot of clutter in the engine bay and clean up sensors, even making it easier to turbo later. 4BAR map W/ baro correction.

From Wiki:
"The 1992–1993 engine has 185 hp (138 kW) at 5800 rpm and 189 ft·lbf (256 N·m) at 4600 rpm. 1994+ have 200 hp (149 kW) at 5800 rpm and 204 ft·lbf (277 N·m) at 4600 rpm. There is no mechanical difference in the engine. In an embarrassing move, Toyota inadvertently created an engine competing with the more performance oriented 7M-GE (200 hp) and 2JZ-GE (225 hp) installed in sportier, more luxurious cars of the time. Because of this; the stock ignition timing and fueling was noticeably detuned. The power spread of the 3VZ-FE is wide, having 100% torque between 2500–4600 rpm, with power trailing off by 6000 rpm. Stock redline is 6600 rpm, and the ECU's fuel/ignition cut is 7200 rpm."

"The 3VZ-FE has a larger forged steel crankshaft and large cast rods. They can handle double the stock power output, although forged pistons & rods are recommended. A few nitrous and turbocharged examples match or exceed 450 hp (336 kW) on both the stock engine and engine management with a piggyback chip controlling fuel & ignition."

I'm really interested in doing a 3mzfe swap, or 3vzfe if I plan to go turbo. I have a few questions for you. What's the fabrication needed for this to fit in the celica bay ( I have a gt, mounts, etc)? Also with the 3vzfe, is there actually room for a turbo setup? And then what about aftermarket support, (engine internals. Pistons, crankshaft, valve train)? Let me know; this is a project I'm really excited about, and I hope to become what I think may either be 6gc's 4th or 5th v6 swapper!

you got the motor choices corect as far as n/a or turbo. you have a gt, and a manual. now you have pretty much 2 tranny choices. your stock s54, or any E series tranny. the E series will be stronger, but will require ST205 front, rear, and driver side mounds, in addition to ST205 shift cables. if you stick to the S54(basically the cheap/easy way out, if your on a budget id go this way, get the swap grimlins worked out, then swap for an E series) its a bolt up affair. with both tranny choices you will have to fab a passenger side mount (easy, or buy one fron fourveesix at mr2oc i believe). there is room for a turbo with a 3vz, but the swap and mounting of everything over the tranny/exhuast piping will need to be VERY carefully planned out. aftermarket support is pretty limited for all the V6s, only real part i can think of is a lightweight flywheel from fidanza. 3vz heads were designed by yamaha and are good (valvetrain wise) to 7500 rpm. pistons, rods and such will need to be custom. my set of custom pistons from wiseco cost 900 (150 each). i should be 6GCs 3rd V6. I'd love to see more!
