You gotta understand thats REALLY FAST for an RX8, it knocks off about 2 seconds off the average RX8s run, and 2 seconds in the 1320 is a very noticeable diff.

If this Kit comes out it will be interesting to see how easily they ca getthe LSx swapped 8s into the 11s.

i WILL be watching

 

If there isn't a kit out by the end of the year, I'll be doing the swap on my own. I'm tired of a fast looking car that is slow.


And screw putting in a stock LS1. LS1 with a nice valvetrain, good size bumpstick, and full 3" or 3.5" exhaust and some tuning, and you've got a car in the low 11s, high 10s.

 

yeah. and the rx8 weighs 700lbs less than the camaro (or gto) that they came out of.

 

sick. would totally do this

 

+1

 

A local customer of mine has a 1976 Datsun 280Z with an LS1/T56 engine swap with some bolt on modifications. (basic block and heads are stock)
He makes just over 400whp and almost the same for torque, a couple weekends ago he ran consistant 11.6's in the 1/4 mile trapping 121MPH.

Daily driven to work everyday and on 91 octane pump gas. Also gets 30mpg

 

How does it get so much hp/tq and get good gas mileage.... does not compute @_@

 

Well with the 6 speed transmission and a 3.90:1 gear ratio in the differential, he cruises on the Hwy at 60mph while the engine only revs at 2200rpm. (somewhere around there)

Your not using 400whp all the time.

But let me tell you.....when he takes the car to lapping days, it drinks the fuel, probably no worse than a turbocharged Rotary would though.

 

Thats a relatively short gear ratio for the diff. My car sees 2200rpm around 85mph and i see 30mpg if i stay off the throttle cant imagine what he would get or what an RX8 would get. If this kit happens and i do this to an 8 then first thing im doing is putting a diff with a long *** ratio. The weight of the RX8 is so little it will help with traction as the second gear launches have shown us lol

 

Oldest trick in the book. A big V8 lugging around at super low RPMs will return rather good MPGs since it only has to be barely above idle to comfortable cruise the car. Hence why a 2000 Si for example will get better fuel economy in the city but on the highway at say 90mph ill be under 3k rpm while his short gears will be over 5000rpm and playing with Vtec

 

Whoa..... Thats what im talkin about!!!

 

So any news on a kit to do this yet?

Preferably before summer of 2010, that way i will be looking at more then the new camaro SS and G8 GXP hopefully

 

If this goes through and I still have my car. Ls all the way.. Sorry guys but I'm just like ricky bobby.. i wanna go fast. lol

 

So uhm maybe we should start a list of who would buy this kit if somebody manufactured it?

I mean im sure many many companies have the capability, just look at the all the engine swap kits available for the RX7, and maybe when they see how many people would be willing to buy such a kit they will actually look into producing one.

This can aslo include people who do not own RX8s, recently i have seen many high mileage RX8s for 6k or less, and blown motor or no motor ones for under 5k, is the kit was priced realistically this could become a very viable option for people who want to build a badass LSx powered car or just for people who dont want the 8 because of its speed.

 

If it was affordable, I'd probably do a swap at some point. I love the rotory, but grew up with small blocks in the garage. From a couple of posts up, gas mileage is great on an lsx power car if you can keep your foot off the right pedal. Hell my dad's 69 Vette has gotten 30 on the highway but usually gets 25 or so. It's a mildly tuned 350 with a 4 speed. It's all in the gearing. Pretty impressive for a 30 year old car. I'll be sad when i go home in a couple weeks and get less.

 

Sick. Sub'd.

 

looks promising whats the progress? i havent looked in a while

 

bump and subscribed =)

any progress? vids? dyno charts?

 

I would buy one down the line subscribed

 

IDK if any of you guys know about this, but Hinsonsupercars is working on a LS1 RX8 kit to sell. Time will tell if it really happens, but if anyone can do it, they can.

i didnt read the entire thread was it ever completed?

 

To pics of it at the track 11.14.2009

 

RGonza went 10.2 at least 2 years ago if not more with his first 3 rotor setup.

 

have they mocked a prototype yet? cant say i have the money right now but would definatly consider if if the set up proved to be relaible.

 

great pics rev up!
