Is it easy?????
 

Is it a better choice to run a b20 turbo in my CRX rather than a B16 turbo??
I have a b16 in it now and wonder if i could just get a b20 long block a use my b16 tranny
or would i have to get a new harness and computer or tranny?????

The cars a 91 crx
B16a OBD0
Its a cable tranny

Iunno its on a whim.....
The torque is wayyy higher and the compression is safer
Figured it would be a better investment than to turbo my B16

i'm going to go ot on a limb and say that your in the wrong section for this........try hybrid/tech........

I'd say stick with the B16. B20's have thin sleeves which are not boost friendly. The C/R may be higher in a B16, but if tuned properly, I'd say it'd be safer than a B20 at the same HP levels. B20's however make nice N/A builds, but N/A is for suckers.

Yeah thanks for the info...I was thinkin of buying a b20 block from a friend for 200 and then throwing my b16 head on it....
But if a B16 can hold a good 7-10 psi on stock internals....with some fuel management ill be good.

if you swap a b16 out for a b20 only to boost; i'll find out where you live and kick you in the nutsack. Not only is the b20 a piece of ---- on the bottom end, the compression ratio of the b16 shouldn't scare you away. It's not that high and just be a nog and stay away from FMUs and get real tuning. Plus does it really matter that the b20 makes a little more torque? The b16 will let you wind the crank out of it, plus it's already in your car.Turbo, tune and call it a day.

Ok....would "real" tuning be..getting some 450 dsm's.....a Pr3 or Pwo already "burned" or tuned....
and a fuel pressure regulator...with umm some other odds and ends...iunno how to do this ----...I dont really wanna go big on it...just the basic ---- i need to run about 7-10 psi...other than the turbo kit....

read this forum more noobie...

how come theres a lot of b20 block with b16 head running around??? im guessing thats a bad idea then???

Re: Is it easy?????
 

they don't have turbos dangling off them unless they're sleeved and built. B20 vtec is alright, lots of people swear by it, but most everyone agrees that boosting a stock bottom end b20 is a bad idea because of the cylinder sleeve construction.
