alright. some of you may know i have a CA. setup for ~300whp. i want more power. a lot more. i thought of building the ca, making a manifolds and slapping a twin scroll t4 turbo on with some sort of standalone. meh..dont think it will be reliable enough at 500+hp. i want something completely different. just cant decide, want some opinions. keep in mind, we can fabricate everything and plan on fabricating everything. motormounts to manifolds, driveshaft(s) to transmission adapters. we can swap anything at the shop, just a matter time.

idea 1) RB25DET. simple. still make my own mounts. intake and exhaust manifold, downpipe, driveshaft. t04 twin scroll tuned with power fc.built bottom end, cams.

2)RB26 with a large single turbo. make a new plenum to compensate 4" inch piping. power fc tuning. make everything like the 25. leaning towards this one because you dont hardly see 26s in the s13. and its a newer motor. but id still build it.

3) 13b rotary. why the hell not? i love the motors. work with a guy that has built plenty. i would have to have twin greddy 18gs make everything i need to. we joke around the shop that we would build an NA 6 rotor just because we can..

4) v8 swap. twin t04e vk56 maybe? something ridiculous. if the letters ls1s show up in this thread i will just ignore you.

also open to any ideas. i had even contemplated a stroked ej25 to eg27.xx twin turbo..

dont think im just dreaming. after seeing what my price for parts is now at the shop and seeing how much ive spent on my CA, i couldve already had one of these by now might get the ca running good enough and keeping it as a daily or selling it and getting a beater and put the cash towards my new project. i have so many ideas brewing in my head, i need some opinions though.

13b all the way.

its unique, and since you say you know someone that can provide the knowledge and labor why not?

i would like to see another rotary powered s-chassis just for the hell of it.

Ignorning the ls1 is just plain ignorant. Pound for pound it is one of the best motors on the planet right now...yes even with pushrods.

If you don't want to do that then build a 7m-gte with forged pistons & rods and a metal hg. They can make 400+ hp with a t4 lexus afm and stock fuel and ecu. Add water methanol and you can make 500+

7mgte? um no. i dont care about pound for pound power. ls1 make easy power. thats not what im going for. your misunderstanding what i want

i think i may do a twin turbo 13b. non sequential. my boss has one in storage that he will pretty much donate. i made a 2.5" dual stainless exhaust this week for his turboII and i fell in love it. the motor he has i forget what he called it but it makes almost 300hp. keep it stock swap except for removing the sequential flapper, and get used to the motor. later on go with a large single turbo and make 6 or 700 with it. it probably wont be a daily driver at that point. and you say another 13b swap? who else has done it? i want to see it.

Wow that is a big red flag right there. The 7m is cheaper and more potent than several of the motors on your list. lol

So what are you saying, That you want to spend more money and make less power?

Sounds like you've already made up your mind. I'm sure it can be done.

free engine = do it. please keep us updated as to what is going on. something this unique would be sure to garner ride of the month or project status.

actually no i havent decided. yes i still have that motor at my disposal but im thinking if i do a 13b or 20b i would just get an rx7. might still do an rb25 but its still not enough for me. thought about the 2jz also because we can easily get them.

The 2jz is an incredible engine, one of the best IMO. Putting one of those in a 240 makes a sick power to weight ratio, you can push 600 hp on a stock bottom end. A 1000 hp 2jz is not rare at all anymore, but im not sure how reliable a 1000 hp car is. It really depends on your goals, but a 2jz is a really sick swap.

However, a 13b in a 240 would have a unique quality to it. A turbocharged rotary has such a nice sound, and the redline makes them alot of fun to drive.

Im not really a big fan of the Wankle though, something about rebuilding it every 30-40k miles or else you lose compression/power doesnt sit well with me..

i may do a 2jz. or my boss really wants me to do rb30 with him. he can do them for cheap. also im buying his turboII fc once i get the money. the same one that has the 2.5" dual stainless exhaust i made. thing sounds freakin sick. so its probably a 2jz, rb30 or build my CA.

little update. bosses turboII rx7 that had the hood stolen, yadda yadda. well he bought 2 rx7s. one turboII with the hood he needs. hes taking the hood and selling it to me for 500 bucks. both had blown motors.

he's taking the twin turbo 13b out of his other 7

putting it in his turboII. a 20b is going in that one instead. the 13b out his turbo2 is going into my turbo 2 or another, more powerful 13b he have sitting around. i could buy the other twin turbo 13b he has also

SO....i already have a 13b, i want an inline 6 in my S chassis. either 2jz or RBxx. which ONE?

2j is the better motor...but if you aren't a millionaire do the 7M-GTE...

If you want to do something unique and want to do fabricating, then do a turbo charged 20b rotary. I think I saw a video the other day with a 13b turbo in an s chassis which was the first I had seen or heard of before. So go on and be the first to do a 20b turbo. It would be unique, strong as hell and would probably be the first person to do it.

Found this for you as well: 497 hp CA18DET
