i am planning on all motor.

i will soon be getting a JDM ITR 4-1 header, cam gears, FPR, and icebox intake, larger TB, new valve springs, and Ti retainers..

I can't decide what cams to get!? I don't do any roadracing....my options probably are Crower 63402's, Jun Stage 2, or Toda spec b's. Stoplight racing, and drag strip racing is about all I do...but I would like a stronger midrange, and much stronger top end. Plus, making power to 9k will be real nice. I like it very much that the crower cams are cheaper, but I am not sure to what power I will get from them.

I can in the future get higher compression pistons, but for now I may just get a mugen head gasket and raise my comp .2 points.

My hondata stage 3 ECU should arrive tuesday(it had better). VTEC adjustment won't be a problem(I really wish there was a hondata tuner in my area)I will get my car dyno tuned, so I will be looking into a VAFC also.

Question is, now that I got the stage 3 hondata, can I upgrade it to stage 4 with the laptop option later? That would rock. Then I wouldn't need the VAFC.....VAFC goes for about 450...maybe uprading to stage 4 would cost about that much.

Oh, and has anyone here replaced their valve springs? Did you have to remove the head? I am thinking it may just be easier to remove the head, and do all the disassembly and reassembly with the head off.

Have to Say the Toda B's .. Plus your going to have the Hondata stage 3 so you'll be able to make the mid and topend Phat

 

Whatever cam you pick, be sure to do the valve springs and retainers at the same time. Springs can be installed while the head is on the car but you need the right tools and experience. Some springs need a special cut to be done to the head, so maybe you should pull the head and have a good 3 angle valve job done.

why not get the Crower 63423 if your only going to be doing street racing...
or go with these

jun stage 2....not too wild of a profile. ti retainers & springs are a must.

 

Yes if you get the Stage 3, you can add the Datalogging and Programming options later. With that, you will be able to change your maps, but you will have to turn the car off to do so. If you use the RaceLogic EPROM Real-time emulator, you can make the changes on the fly with the car running.

If you have any questions about Hondata stuff, go ahead and email them, they are very helpful and very prompt about replying.

Hope your research goes well!

 

That is what I want, real time data programming. I could optimize my car quickly that way on a dyno.

Thanks about the info guys. I will probably remove the head to do the cams....while I do it I should get some of those flat faced valves too...to raise the compression a little bit.

Does anyone have any experience with aftermarket cams? Like toda, JUN, crower????

 

i am in the same situation i have heard great reviews about the juns and toda's but cant decide which set to get peeps have told me todas have be top end but require a higher x over and the juns a great too with a lower vtec x over but make slightly less power than the toda b's

 

You might want to look here then.

I guess JUN stage 3 cams have great highend, but are below CTR and Toda cams in the midrange. The jun, and for that fact toda cams both need very well breathing motors. The Jun stage 3's don't make killer power until high rpms, and the toda make good high end too(just not as much). I would have to say the Toda spec b's are looking like the best option. Not the strongest highend, but I would have to say they are great for the street. Reving past 9000 all the time would be really cool with the Jun's, but not all that economical. Toda Spec b's seem to be the best for the street...good midrange, and good highend. Plus, extreme RPMS not required to go fast. I hear the higher VTEC recommendation is around 6200 rpms...but who cars, cuz the non-vtec lobes make great power as well!
