You can't ask that question. Why? Cause we don't know your setup, your CR, what kind of cams, port and polish?

I say get some 440cc RC injectors, don't do the ghetto DSM injector thing, spend the money. IF you can afford to build a full engine, you can afford proper injectors.

The main part of injectors is TUNING, we can't stress the TUNING enough. Get the car tuned professionally on a dyno.

I'm with ludes on this one..
IMO used injectors are just that USED!
I know from experience in the past injectors used up injectors can be clogged or have a poor spray pattern.
Can you use 450 DSM injectors? Yup,but if you have tuning issues don't be surprised if they need to be sent out to be serviced.

Once again IMO I'd buy a nice set of 440 or 500 RC injectors..

I bought used 750s, spend $10 to have them checked and flow tested at a shop. :)

I got used injectors, had them cleaned. So what? New gaskets. New screen. Still a lot cheaper than new ones. All were perfect on the bench cleaner machine.
They do them for I think $25 at Napa here in town.

Like I said it's all a matter of preference guys.
If you can get the injectors cleaned and flow matched for cheap kudos to you.
I personally am not willing to risk my setup on used injectors thats all.

I have ITR cams. On the dyno I got 165 at the wheel I believe. I cannot remember the torque, but it was not that great, the drawback of the b16.
It made power all the way up over 9000 rpms. Like a sewing machine.
BTW you don't need new injectors if you are staying with 1600cc's. Stock do just fine as well as the stock fuel pump.
Since I used this to drag race at times, you had to launch close to VTEC engagement because of the lack of torque. Got sick of it and am putting together a cr-v/vtec now with low level of boost.

Yes. I have it all. Thats Hp at the wheel, not at the crank. Add another 20% or so for hp at the crank?
Have b16a
Hondata s200
CTR pistons
ITR cams
titanium retainers, heavy springs
Port and Polish by Portflo design
Enlarged throttle body
Skunk 2 intake
DC sport 421 exhaust
ACT clutch
YS1 tranny
With slicks it can do mid to high 13's although to be honest, I can't get it there, but another driver can.
This is why I am going bigger, new bottom end and adding some boost.
Let me know if you do better.

aight damn i was worried for a second. thats good. well im not coming out until may so i guess youll find out what my track times are in may. how many miles did you put into your motor to break it in and are those injectors plug and play or you have to do something special for them to work.

The pistons were done before I got the car. I did the head work.
DSM 450's use the same connectors and the resistor box. You just regulate them in whatever you use for fuel management. I use Hondata.
Again, I was told the stock ones would be fine for up to 200 whp.
I got the 450's for my new setup.

I don't think hondata makes it anymore for obd0 but some of the guys here can tell you some options. Its just not worth it. I converted to obd1 with a conversion harness, p28 ecu, new dizzy, new 4 wire O2 sensor, and hooked up hondata, but there is "chrome" with a "dongle" adapter for your laptop and other shareware software that can help you with fuel management that costs less money and you get the same outcome. With your setup you need to have fuel/ecu management. It will never run right otherwise.

You can't just swap the fuel injectors for different ones without having some way of adjusting/controlling them as well as other things like vtec engagement etc.

Start a new thread if you are interested and you can find out your options.
