I am going the CA cause its legal and powerful. I was going a NA SR20 but after speaking to a few engine builders it turns out it would cost way too much to get power and you would have to wring its neck to make that power so it would be a tad unreliable. If it was legal I would jam in a 13B turbo, awesome power and good weight.

If you really wanna go fast and have fun then fuel economy can get facked :)

A12GX :)

wat bout 13b non turbo is that legal cooz i would luv to smash 1 of them in the 1200

sr20det vct all the way

nah can only go 1.2 litres for rotor, all those figures are halve for what you can have for a rotor i'm pretty sure, so 2.4 piston or 1.2 rotor n/a

i think you can go past a rotary. ive had 2 13bt powered 1200 utes. one i still own and one i sold. both wild as hell cars to drive. the first one i had was a standard series 4 13bt with no mods. car ran a 12.2 @118 mph quater. if i had traction i have the mph to run an 11.3. car had heaps more in it. just struggled with wheelspin.

ive driven a mates ca18det ute. my mate has had more trouble with it then any rota i have ever owned. blown head gaskets. etc

if you drive a rotary properly with good oil and good fuel supply you wont have any problems with it. unless you over rev it and dont warm it up.

with both engine packages there is enough power to beat most cars on the street and they are both fun to drive.

the issue i had with the ca18 is the shifter sits to far back in the car as to the 13b it sat forward and was easier to drive.

the rotary made power strait away as the ca was power at the top. maybe different in other cars.

even if you put a 12a in the car with porting it would still make good power. just as much as a 13bt if the right guy built it.

another plue with the rotary is that its heaps lighter and heaps more room under the hood.

each to their own i guess. hope this helps out

A ported NA 12a is a pig in traffic, my 12a bridgeport was fun at high revs but the 13b extend was much more fun in everyday situations it didnt make you want to rev the crap out of it like the 12aBP did. A turbo rotary is the perfect combo not an NA rotary for the street. However as mentioned earlier impossible to register in most states. The problem with the rotary now is the price of rebuilds and parts they have more than doubled across the board and most drag racers that where into rotaries are now going the 2jz. Enthusiast are not happy about the costs and neither the 2jz mushrooming effect across the drag strip.
Good rotor rebuilders and machinist are not common or have quick turnarounds.

As for weight the CA is much lighter than a rotary in NA or turbo. The rotary has a compact form factor, inefficient put supremely powerful for its size.

There are plenty of well setup rotaries and ca18det but when it comes down to
economy, budget replacement parts and ease of install and registration the
CA is way better than even an SR20det.

I have a custom single rotor 13b which Im playing with at the moment
it was in a turbo escort sports sedan with a PP housing and making 280hp.
It only came to life at 6500rpm once the t3 was at full boost.
It blew the clutch at perhaps 12,000rpm when the accelerator was stuck.
It drank fuel like a big block v8 and sounded like a virgin busted by Long John Silver.

any modified car is a pig in trafic. as for the weight of a ca18 vs a 12a ( both na engines). the rota is heaps less. how many modified cars sit in trafic and dont overheat

there is pros and cons with every motor and every modification.

if you look at all the rotor guys who have gone 2jz is the guys who own the rotary shops. example craig dyson from dyson rotary and also maztech have gone that way aswell. gas motorsport made a deal with them to run the cars

these guys have been racing cars since the early 90s. and i dont think they find it hard to find parts.

any motor cost big bucks to build if you want it done right. there is heaps of blokes who rebuild rotors on the cheap and have no drama. if they were that unreliable why would they build the rx8

i would go the rotor, only cause when i had my CA it was a ongoing money pit, yeah i know rotories dont have good reputations but i think people who say that never drove one.. i have been around rotories for a while and the reason i went for a rotor instead of CA is i dont want full power or the quickest car on the street i wanted a cruiser for weekends that sounded like sex on wheels and i can tell you chicks love it and if the day comes i want power i can assure you no CA will ever catch a decent 13b, you tell me who has ever seen a CA with over 1000hp? ive seen rotories at that figure.... and i know a 20B rotor would fit in a datsun and put out over 500kw on standard n/a..

but its what you want to do with it...

lol if we are talking street cars then im pretty sure a modified CA18DET would catch a modified 13b... considering you cant register a 13bt
