A friend of mine in Idaho perpetrated it with a friend of his out there. No build thread that I'm aware of, just the trophy shot.

Just recently in this area there has been a rash of 70 mile cars in the sub $5500 market. I think an LS1 RX8 would be the perfect daily driver - more practical than a Miata for those of us who occasionally need back seats, and I personally prefer a hardtop in very high performance cars. Keith, I'd buy one of your RX8 kits. That said, a quick email to Hinson a few months ago confirmed that while they suck at website updates, they do have a compete RX8 kit available, with working factory gauges.

lol an LS1 with 10-11krpm tach, thats gotta be dissatisfying.

You should be able to build on that will spin up to 7500 alright. Not quite 9k but better than the stock 5500 rpm.

there's lots of debate over the topic. I love the little motor and less cubes = less fuel when cruising. Plus, we've alaready seen that the 4.8 will handle umpteen pounds of boost and make ridiculous power when boosted.

Yes and I am decidedly on the other side from Bob. Give me a 7.0L and the extra HP/TQ that it comes with in the same weight package. GRM should by Bob and myself an RX8 with the engines we're both vying for and we could compare them. I think we'd both be happy.

Yeah the 5.3 and the 4.8 are boost happy monsters, I want one in my truck. Hell, I'll even take it without boost!

In reply to fidelity101:

Does the semi-mythical L33 (aluminum block) count for being boost happy? I can't bring myself to sacrifice the additional 80 lbs or whatever with the iron block over what is probably less than 600 dollars.

I second this motion..... all in favor? AYE!

Mine would be a cross country tourer/daily driver. Since I drive almost 50 miles a day, the 4.8 with a nice little cam, FAST intake/TB and tune would make it perfect in a car that size/weight. Low 30's on the highway, stupid fast on track..... Everyone is happy.

Now... when can I expect delivery of my RX8/LR4?

Correct. LS1 vette/Camaro's were 6500 IIRC. My LR4 is 5800-6000 (depends on how fast you get there and how quickly it can shift) with the monster truck intake.

In reply to Bobzilla & Javelin:

My FIL has a 1500 with an LM7 and it is south of 6k. Don't recall exactly where but down there somewheres. I would be starting with a truck based motor anyhow so cut me a little slack there Jav.

AYE!

I love the RX8/V8 idea and I would gladly race my hypothetical combo against Bob over there in his hypothetical combo and he could talk about how "rev happy" his is while I mop the floor with him on the roadcourse.

rev happy... hehehe

In reply to Bobzilla:

While a 7.0L would be AWESOME, a 4.8/5.3 makes more sense to me overall. The fuel economy is an issue no matter how I don't want it to be. There is also the initial cost. If I can get a complete install kit for 5K or something like that I don't want to spend another 10K on a LS7.

I'll bet I can get within 2 mpg of Bob and his combo.

Plus, you can get 7.0 without getting an LS7. More expensive, sure, but I was exaggerating. If, for equal money, I could get more cubes in the same overall package, I would. Then we could race.

My money's on tuna's LS7 version (and that's how I'd go), but I can see the DD merit in having the "baby" 4.8/5.3 in bob's version. I'd really, really like to read that comparison!

Well think of it this way, People love doing v8 RX to all gens of the rx7, each newer gen has a much better designed suspension and overall chassis.

FDs are expensive and becoming harder to find. A decent roller shell, rust free nice interior and etc is near the same price as a running/driving rx8 and it weighs roughly the same but has an even better suspension. Looks are arguable because beauty is in the eye of the beholder. I personally like them both and if we are talking theoretical race cars here, I'd have one of each.

We are all really saying the same basic thing, we just see the uses a little different. Anyway, good talk gang.

Also, you could use any motor with more than 2.5L and make more power than the Renesis. Maybe not HP but what more torques!!!

Funny enough, if I were building the ultimate Lemons car, I'd want a rotary. The ultimate street car? LS series, please. The rotary makes an excellent race engine, just a crappy street engine.

The packaging of the RX8 is brilliant, four doors and lots of room in the back. Add to that that it handles 100x better than anything else that you could say "the packaging is brilliant..." to, and yes, I want one badly. With the V8, of course.

I doubt that -with more than double the whp and tq of the rotary (and better fuel efficiency) - there would be anything dissatisfying about it.

What's next, an argument about hp/L?

Oh gosh, let me nip that one quickly:

HP/Liter is important!

No it isn't, you're an idiot!

HP/L means it's efficient!

NO, HP/lb and HP/fuel and HP/exterior dimension means it's efficient!!

and then...

A rotary only has 1.3L!

No it's 2.6!!

No, it's 3.9!!!

No, it's {complicated formula}!!

ok, now moving on, RX8s rule, V8s rule, continue.

I like torque, not using oil between oil changes, fuel efficiency and V8 sounds. All of those are the opposite of a rotary.

I like all of those things too, except I like that they are in my truck (except I wish it had fuel efficiency).
