Supercharger or Turbo

well am trying to make up my mind and i want to get more power out of my gxl and was thinking either of buying a t2 engine and putting it in there (instead of putting a turbo on it and having to deal with high compression rotors and possiblly detonating the motor) or doing a 600cfm holley carb with a camden supercharger, its just when i think of an fc its usually turbo
so what do you think and if there is anyone with a carb and camden on an fc please tell me what you think of it and what kind of horsepower you get

youd get more info on the supercharger in the first gen section. The thing is that the T2 swap would net you more power and much more headroom for making power than a carb and a supercharger. The supercharger is expensive and doesn't really add all that much power

i agree.


but the newer SC kits dont need a carb, they made an intake manifold that you can keep fuel injection

For the price of the camden supercharger EFI kit (~3500 ?) you can get a j-spec engine (~1200), rebuild it with a port job (~1300), get a BRN hybrid (750) and a SAFC (200) (or megasquirt) and have far more power than the supercharged car.

turbo. you will be much better in the long run, cost wise, like sideways7 said. the last supercharger build thread that i read consisted of several complaints of belt slippage, and other various problems. plus the jspec/rebuild/port/bnr/fuel computer combo would kill the s/c rx even if it was running properly. but i guess if you think that your sort of needs and applications would do better with a constant power instead of turbo... by all means go for it!

Agree with above, UNLESS you dont plan on going ***** out. But even then the turbo route is cheaper, will go faster, be easier to do, and you will have a LOT more help if something goes wrong.

That being said a roots blower would be fun on a rotary. you would just need to be careful about intake temps.

well i do agree with you except on one thing you said easier to do um i dont thing putting a turbo engine in would be easier than putting on a supercharger

i know the supercharger route is easier but i honestly want a turbo and thats what you guy seem to say. right now i dont want to have to get it rebuild because of money but eventually i will with a street or half bridge port. how much would a turbo 2 engine with only 50,000 or less mile on it cost

is there a site where you can get jspec engines
and yes i know they make efi kits that are 3500 the only reason i said the carb way because a 600cfm carb about 300 plus the 7inch camden that goes with carb is only 2300 and those are cheaper than the efi kit

just put a turbo on the stock n/a engine. If you upgrade to the T2 ecu, injectors, pressure sensor, afm, intake manifolds, and turbo it will be a hell of alot cheap than either a jdm swap or a s/c project. If you port your wastegate and run stock boost you'll be fine. Better yet upgrade to the rtek 1.7 and run 720cc secondaries and you'll have no problems at all .. .beleive me i've done it

www.Corksport.com is about the only reliable importer I know of.
And I just threw those numbers out there as an example. You can periodically find a full TII swap with a used engine for a grand or so. You can't reliably find them, though, you just kinda have to stumble on them.
And if you want a turbo then DO NOT get a supercharger. You will never be happy with it and will always wish you had spent the money on turboing it. Some people like them supercharged, and I'm sure they are lots of fun. Its just that they are very different animals from turbo rotaries and if thats what you are wanting then you will never be happy with a supercharged one.

well i told you the na motor has high compression rotors in it and stock boost is all about what you can run so i dont want to put a turbo on it and then detonate it by accident

Swapping an engine out is not hard at all. TURBO ALL THE WAY!! It can easily be done in a weekend with proper tools and some common sense.

you can run more than stock boost with the n/a block. High compression isn't a bad thing! If you get an rtek 1.7 with some 720cc secondary's you'll have no problems at all maxing out the stock turbo on there.
