Do you guys think it'll be a simple bolt on if I do a Manual Tranny swap with a 2JZ 6SPEED TRANNY, for a stock 2JZGE.

The W55/W58/R154 swap has be done many many times in the IS300. You can search and see numerous posts on parts lists and DIY projects.

The V160/V161 is pretty pricey and not really necessary unless you are looking at building a 700+ hp vehicle.

The JDM Supra SR-Z had a V161 on a 2JZ-GE, so it's possible, but there's really no reason to if you're not going to turbo the hell out of your car.

Nearly 7 grand for a new v160? Damn, didn't know they actually go that high.

What are the main differences of a w55, 58, and r154?

strength and smoothness

r154 - strong, good enough for 700-800, clunky shifting
w55 - weak, 300-350, though people have made 450 being gentle, smooth shifting
w58 - a tad stronger than the w55, but not much..., still smooth shifting...

W55

This was the first of the aluminum-shelled W-series transmissions.

The W55 appears to be a base reference point for gear ratios that Toyota used to fine tune later models of the W-series.

Ratios:
First Gear: 3.566:1
Second Gear: 2.056:1
Third Gear: 1.384:1
Fourth Gear: 1.00:1
Fifth Gear: 0.85:1
Reverse: -4.091:1

Applications:
1982-1983 Toyota Carina
1981-1985 Toyota Celica
1983 Toyota Corona
1986 Toyota Soarer
1986 Toyota Crown
1983 Toyota Chaser
1984-1995 Toyota Pickup 2WD with 22RE(EFI) engine
2002-2005 Lexus IS300 (US Market only)


W58

It differs from the W57 in its fifth-gear ratio. This transmission is popular as a replacement for weak stock transmissions in other vehicles. It came in two varieties: the original found in the 1982-1989 non-turbo Supras, Celicas and Cressidas of the early 1980s; and the later version found in Mk3, Mk 4 Supras and Lexus SC 300s.

Toyota lists a change from an alloy sandwich plate to a steel sandwich plate around 1989. The steel sandwich plate has some minor internal differences, and it is believed to be slightly stronger (some wider bearings, some wider gears, slightly different gear selection mechanism, etc.). In theory the all-alloy version of the W58 should be exactly the same strength as any other all-alloy W-Series transmission. The steel plate version is considered much harder to find and worth approximately three to five times as much as an all alloy version.

The ratios and bolt patterns remain the same regardless of the sandwich plate used.

The W58 & W57 share the highest gearing and closest ratios (1st, 2nd, 3rd, and 4th (direct)) of the stock W-Series transmissions.

The ratio shift was accomplished by taking the W55 base ratios and changing the input shaft to intermediate shaft ratio by 7.9%, thus shifting 1, 2, 3 ratios higher by that amount. This also shifted the overdrive 5th gear higher by the same amount creating a wider and taller overdrive ratio.

The W58 is sometimes designated as a "close-ratio transmission"; however, in its stock form it does not meet all the criteria for a close-ratio box.

Toyota engineers have shown favor to the W58 over the rest of the 'W' series by including it in so many models and even building a stronger version for higher powered applications.

Ratios:
First Gear: 3.285:1
Second Gear: 1.894:1
Third Gear: 1.275:1
Fourth Gear: 1.00:1
Fifth Gear: 0.783:1
Reverse: -3.768:1

Applications:
1982-1986 Toyota MK 2 Celica Supra
1986-1992 Toyota MK 3 non-turbo Supra
1993-1998 Toyota MK 4 non-turbo Supra
1986 Toyota Cressida
1986 Toyota Soarer
1982-1992 Lotus Excel
1992-1997 Lexus SC300
1998-2005 Lexus IS300 5 speed


R154

This is a robust 5-speed transmission found in the MKIII Supra Turbo, Toyota Chaser Tourer V, Toyota Mark II Tourer V, Toyota Cresta Tourer V, and Toyota Soarer (turbo) up to 2004.

Ratios:
First Gear: 3.250:1
Second Gear: 1.955:1
Third Gear: 1.310:1
Fourth Gear: 1.00:1
Fifth Gear: 0.753:1
