stock ls1's? That seems kinda high. Who knows.

jeremey's did 125ish on his cam that was n/a. There's always the bottle.

The white one running around here has a 125shot. I've never seen him squeeze it. He makes 500hp n/a in his ls6 swapped car. Im sure he is mid to late 130's easy on traps n/a on the bottle who knows.

so yeah take it with a grain of salt. There is always a faster setup. The difference is the ls won't be blowing out apex seals.


btw congrats on spooling full at 4k. With a 1.3+ a/r turbine thats not an easy feat. Most big single turbo 7's i've seen get full spool around 5-6k.

Its all in what you are after im sure everyone knows this. But, alot of mis information being thrown around about how much a ls swapped car can be had for not to mention their power level's. The ls just has more displacement and will make more power more reliabily. Simple truth.

Its why mani's 03 cobra could do 900hp on the stock motor. Displacement helps alot. Its what the little rotary is lacking alot of. So when running 600-700hp through one they really don't last. The bigger the motor the easier it is to make stupid power and the longer it can last.

Like I said jermey's drove for years under that configuration. I've never of a 7 being driven daily and raced weekly making 450-500hp last for several years without breaking.

If you've got one that does. My hats off to you. I'll stick with the larger ls motor being more reliable at higher hp ranges than the 1.8ltr rotary..as the general rule of thumb

What engine is the 20b from originally? Is that the one in the rx8?

Awesome looking car!

From a Cosmo (never brought to the US). The RX8 has a Renesis rotary. The swap for the 3 rotor is nearly as involved as an LS1 swap...

John and I are just going to have to agree to disagree I guess. As for the 20b swap yes it's as involved as an LS1 swap. I have friends running 13B T51 turbo cars that are making good power and they question why I would go through with the swap when I can make as much power from a 13b. My answer is to be different plus I've always liked the sound of the 3 rotor. I'm not doing the swap because of any supposed short comings of the original engine.

I've also got a 3 rotor peripheral port going into the 914 track car that I am building. It's going to stay N/A and make 400+ HP. I found 4 peripheral port 20b videos on youtube. The first one in the series is:

go with 20B 3 rotor single turbo

MPD47

And spend $20k + before you really get into the turbo setup.

SoloRacer

A 20b swap would be no different cost wise than a LS1 swap. Unless you can prove otherwise.

SoloRacer

The reasons for staying N/A on the 914 is to keep the throttle response and make the install less complicated.

Let's call the Hinson parts to put in a 20b or an LS1 a wash (in terms of supporting parts to install them). A complete LS1 setup can be bought for $3k, with ECU, trans, clutch, etc. So ready to rock. Call it less than $1200 for a rebuild. (Including upgrading to ARP rod bolts so you dont get that stupid bolt stretch and blow the bottom end apart when you try and do anything). Last I checked for $4200 you couldnt get near a rebuilt 20b, much less turbo'ing one.

SoloRacer

The 20b comes turbo'd from the factory - it has sequential twins. If I am building the engine myself - something you must be doing for the $1200 you quote - I could do it for the $1200 (roughly the price of new seals, etc.) I also paid $3000 (Canadian) for my 3 rotor engine including transmission and ECU. Not much difference is there?

MPD47

*shrug* That's significantly lower than I had read/been told for the 20b.

I dont expect us to agree on this, you're clearly a rotard and I'm a born-again ohv lover.

SoloRacer

And your LS1 conversion prices are signifigantly lower than what I have been told for an LS1 - and I have a friend who builds them and installs them in 3 series BMW's. There is a beautiful 968 that has been converted to an LS1 and while I think it's a nice car I much prefer my turbo'd 968 - and in the end it is my belief that my turbo 968 is worth more. I really can't think of too many engine conversions in any car that are worth more than keeping the car true to it's original heritage. Maybe a 4 rotor Corvette conversion will be the answer

MPD47

I've been thinking that buying an R32 GTS and swapping an LS1 into it would be good enough to REALLY **** people off.

I dont think the 951/968 NEEDS to be swapped. I can see it being very fun, but I prefer pissing money away like it's water after a night of drinking trying to get all I can out of them

It arrived on a carrier yesterday morning. It is about as clean as the seller said...really clean. I think for now I will put in a used 13b just to make it driveable. One big problem with it though, I'm 6'6" and do not fit so this will have to be dads car.
I did drive it and it blows smoke but it is a tight car and everything works including the rebuilt Bose radio. I told you the previous owner was meticulous.

I will try to post picts later.
