The basis for %age power loss is power at the crank, not at the wheels. If power loss were 25%, then 550rwhp would equate to 550/(1 - .25) = 733hp at the crank.

25% loss does not mean you multiply rwhp by 1.25 to get crank hp. You have to divide by (1 - .25), which is the same as multiplying by 1.333. I.e., the power loss percentage going from crank/flywheel hp to rwhp is not the same as the apparent power "gain" percentage going from rwhp to crank/flywheel hp.

Isn't the Atom powered by a built Honda B16 engine? Or was that a different TG episode? Lol ...or, I guess they have a V8 version now that uses the engine you mentioned?
The stock Atom is powered by a Honda K20. Which is by the way, a fantastic I4 (can be tuned to like 300hp NA, and with the transaxle is almost as light as a 2ZZ-GE + C60, which is impressive considering it makes way more power and is way more reliable). The FA20 is an okay engine, but the boxer configuration, 2013 precats, and dual injection hardware weighs it down some. If you're going to compare an LS3 +T56 weight wise, it's more of a fair fight to compare against an older motor with higher emissions like the K20.

You can get a similar V8 to that here: http://www.h1v8.com/page/page/1562068.htm
I think it's 30000 dollars for the engine :P

Yummy :9

Seeing how this kit will have nice headers and a mandatory intake already (since it's not a stock corvette afterall with a factory airbox lol), I am sure this will add a decent amount of power and will surely be above 400whp with a crate LS3. So with the headers and intake already included in this kit, all one needs is a tune (and/or cam) if someone wanted the usual bolt-on mods/upgrades

Really looking forward to seeing their included wiring/ecu/electrical harnesses too.

not putting a cam in a OEM LS engine is like not putting good tires on an frs.

Yes! A/C, P/S, full interior, etc. I've taken a few LONG trips in it, including from Providence, RI to Beeville, TX for the Texas Mile.

Very nice..Love the FD!

I just saw under your avatar you have a 240z too...man, that too is a nice ride. The FD is super nice too...but I think I woulda put the LS in the 240 ...always dreamed of the old 240 and 510 cars.

I think this would be very similar to an FRS with a crate LS3 or LS376 Hot Cam 480 in it, regarding Weight and Power.

280z (similar to the FRS at about 2850lbs; unlike the much lighter earlier 240z which was 2300lbs) and this also has an older/lower model LS1 (but with heads/cam and getting around 450whp, which is similar in power to a Hot Cam crate LS376/480.

I really wanted an RWB Porsche. Nakai-san is brilliant, and the cars he turns out are incredible works of art. However, I couldn't bring my self to save for 5+ years to be able to reasonably afford a $10k+ bare shell, $20k for just a body kit and paint, and then who knows how much in wheel, suspension, so on and so forth, and then having to do some totally off the wall swap like VR-T or something because of the RR configuration.

To me, the only thing that comes close to an RWB in terms of class and style is a Rocket Bunny 86. The FR layout which can utilize powertrains which I'm more familiar with and has been proven to work with my favorite engine, the JZ, sold me on the idea. The fact that you get to build it yourself is just that much more enticing. RWB's you have to send out to get the kit fitted and painted. Which is sweet, but it also adds a lot of cost that I just couldn't justify.

And versus just buying a new, similar car? I would never be interested in something so exotic that you're totally boned if you blow it up driving it hard. The brilliant part about JZ / LS swapped cars is that you get the performance without sacrificing durability or ease of service.

Is anyone making FRS bolt on kits for the 2jz engines?

How much do 2jz engines go for these days? I assume pretty cheap?

What trannys work with a 2jz in an frs chassis?

How much does a 2jz weigh? With and without tranny?

I kinda like the idea of 2jz, because it's toyota and also an import engine still. And I like the idea of LS3 because it's NA and also can be easily bought brand new or found with low miles. 2jz will most likely be old, needs rebuilding, and is also a turbo and also cast iron.

This is why I prefer the LSX motor. Cheap all around. The 2JZ has sex appeal for sure, but for a simple motor that will just "get it done" on the track and take the beating without an issue, I would pick the LS motor personally. Either swap is bad ass, just my personal preference. Says something considering that I've owned mostly Fords

Xcessive Manufacturing makes engine mounts but you're on your own after that.

I believe aristo vvti 2jz's are in the ballpark of $2200 but you'll need a manual trans

anything will need fabrication around the tunnel but I would go with an R154 or a nissan Z33 6-speed.

around 450lbs dry with accessories but without flywheel. It's also LONG and barely fits in the bay.

most 2jz's only need new gaskets which are cheap. Rebuilding one is a waste of a perfectly good high horsepower capable rotating assembly.

Sad to say I partial-traded the Z for the FD. Gave up car I built from dead stock to a 255rwhp street/track monster that took on and beat Z06s, Vipers, 911 Turbos etc. at the track. in its (and my) day

The Z is a much better platform for such swaps because of its basic architecture. To accommodate a LONG inline 6 while maintaining 50/50 weight distribution (mine weighed in at 49F/51R with fuel and me in it), the front wheels are shoved way forward of the firewall. This means you can swap in a large-displacement V8 and *IMPROVE* weight distribution (move it rearward), which is pretty critical to putting down a lot more power. Also, an LS V8 not any heavier than the stock iron-block aluminum-head inline 6, so near-zero weight gain.

With the FR-S/BRZ, some critical factors are working against you:
1. Front-biased 54/46 F/R weight distribution with driver and fuel might not seem too far off from 50/50, but that's 8% less weight on the drive wheels. Not an issue with 200hp, but it becomes significant when adding big power.

2. Since the stock engine is a very short H4, so just about any engine you swap in will have its c.g. situated well forward of the stock engine.

3. Since the stock engine is an aluminum 2.0 four, just about any big-power potential engine is going to be somewhat heavier, so the car is heavier and the c.g. is moved still further forward

In the end, with an LS FR-S/BRZ you'll have a ~2800-2850 lb. car with ~56/44 weight distribution with driver and fuel, vs. the swap in the 280Z where you'll be about the same weight with 49/51 (or better) weight distribution. The Z will have 14% more static weight on the drive wheels. That's HUGE if you're trying to put down ~400rwhp in a car of this weight.
