Just like the title says, I need a little help deciding what would be better for me.
I picked up a 90 crx si off of a member on here. Bone stock motor, has nice suspension mods. I want the car for a reliable, quick, daily driver/ fun track weekend track car ( drag racing, and I might try auto-x a few times )

What would be better for me ?

D16z6 Sohc vtec motor
OBD-1 Conversion
Jrsc with 6 psi
chipped p28 tuned
i/h/e/clutch

or

Jdm B20b swap
B16 or LS trans
OBD-0 with Ls ecu
I/h/e/clutch

I am leaning towards the b20 swap because there is more I could do in the future if I wanted more power. Help me out guys !!!

 

anyone have any input?

 

which is cheaper?

what motor do you have now? you said SI w/ bone stock motor. D16a6.


why swap for a d16z6? waste of money in my opinion.

so now it comes down to B20 swap or slapping a supercharger on the d16a6.

which is cheaper?

 

Why no Love for the LS B18a are dirt cheap now adays and its an easy swap into and Si, I think it wakes up the CRX a little...but the SC would be nice on the a6...but for reliability I say stay N/A

 

well, they both are gonna put out around the same power. the d16a6 is already in your car, so no extra mounts, axles, other swap stuff needed. i would go with the d16a6 because it should be lighter then the b20. you can also always build the d16a6 up and do aftermarket rods and pistons, and then get the lht intercooler mod for the jrsc, and the endyn work on the jrsc too. dont forget the LSD too. im no longer really a big fan of turbos. i like supercharged and NA personally. non vtec d series motors supposedly are more suitable for supercharging as compared to vtec d series motors.
check out the d-series.org forced induction forum for more ideas on supercharging d series motors.

 

thanks guys, streetworks, i meant to IM you personally, the reason i was going to use the d16z6 is to kind of upgrade from the d16a6 int the car, for the sole reason that running obd1 is more "tuneable", and also my d16a6 has 222k on it that i know of ( motor looks original but i just picked up the car )

and with the b20 or ls like loserkidwac said, it would be drop in with mounts and linkage, and still run obd0 with stock ecu and minimal mods to make probably as much power as the supercharged d-series.
Cheaper really doesnt matter I have 2 grand cash to spend, it is more asking for help on what is better for what I want to use it for....

you can run obd-1 on a d16a6. the d16z6 and the d16a6 will actually make pretty similar numbers with a JRSC.

and if you are only keeping the b20 or ls stock. dont bother. the JRSC car will smash on it all day long. with minimal amount of work, you can have 165whp and 140wtq out of your single cam. no problem at all.

 

you can always change the d16a6 to obd1 and get all the advantages of that, CROME, 4 wire o2 etc. i also agree with what joe said about the jrsc d series. a stock LS, puts out what about, 120 whp stock? get the jrsc, you will have better low end grunt. also, remember that if you get the b16 tranny, you will be high revving all day on the freeway. well compared on the stock LS or b20 redline. keep the d, let LSD, headwork, bottom end rebuild, jrsc. then you will be set for another 200k or until you decide to further modify it.

 

also, another thing to look into with the JRSC, is checking with jackson racing and seeing if they will be developing a rotorex? supercharger kit for the d series (as compared to what it is now). the new JRSC superchargers are far more efficent supposedly and can make more power easier.

 

i really want the supercharged d16a6, just don't want it to turn out into a nightmare car, I would much rather it be right from the get go.

Streetwerkz, check your pm's

 

how bout screw all this **** and go ls vtec? like loserkid said b18b's are dirt cheap and ive seen fully built b16 heads go for like 500 bucks...cheap...fast...plus you can do more down the road....n/a all the way

 

i have another car the I am building a N/A setup for as we speak, thanks though
