What are the benefits other than the obvious?
Any concerns to worry about since I am turboed?
Will new springs and retainers raise it up and by how much?
What else can I do mechanically to do this?

Balance your crank, rods, pistons and upgrade to new springs, valves and retainer. Can you say 9k rpm?

Im just curios about the retainers and springs. Balancing I have no clue about and all that. I am jsut lokoing for the simpilar stuff right now. thanks for a response.

Anyone know of how much higher it would be with just springs and retainers?

 

Upgrade valve train with titanium retainers springs 10k!! But you wont be able to shift that high tranny cant handle it and it wont go in. 9k no problem though.

 

I have a d15 in my crx with exhaust and K&N. What would it take to get it to rev to 8 grand? is it really that expensive? I wonder if it's really worth it.

 

its only worth it if you are still making power. if you crest at 7800, then 8250
is a good place to stop. if you arent going to kwwp acclerating and have no
upper end torque> why raise it? the other thought I have heard is that bangin
the limiter is so not good for the engine that it is almost better to raise it if you
have a built engine so you will never hit it. I have a valvetrain that can hit
the 9K+ numbers now, but I am weary for the GSR bottom end. I am still
researching it.

 

Raising your redline has its benefits and its down sides. Usually the stock redline is ample enough for just a mostly a stock motor.. remember Honda put the redline there for a reason.. they put research into. If you have the power curve that requires you to have a higher redline in order to use it to its full potential, then go for it. While valve springs and retainers wont raise youre redline by itself, it does relieve a lot of stress that your motor will be put upon. Get your ECU chipped, make sure you get a chip that is based upon your modifications. My ECU was chipped by prospeed. Fuel cut-off is set at 9500, has my motor ever seen 9500?? NO WAY. not with its current stock valve-train. its seen 8300 safely. Honda did put some slack in its motors. believe it or not, these already strung out motors, can be pushed even more. i have a d16.. and i have never had problems revving too high. although this is my 2nd motor. my first motor snapped the timing belt, but it had 160,000 miles on it, and it revved nicely to 8000rpm.

 

chip it? What are we VW's in here. Come on. If anything I would have a hondata and do it that way rather than screw my ECU with some prefab chip where my curves are jacked for my turbo. I wont chip it cause the springs and retainers will raise my limit enough to where I need it. I make horse-power all the way up the band and it does not stop until I rev limit, but my Torque does start to taper off earlier. I would more than likely raise the rev lmiter so I don't bounce off of it. while at the same time be able to lengthen the time I am in gears. maybe bring down my times into lower 12s.

 

upgraded springs and retainers raise ur redline??? im confused. thought fuel cutoff was controlled by ECU. titanium valvesprings and retainers may allow you to safely rev higher, but it doesnt automatically raise ur redline does it? i dont see the logic behind that....

can someone explain this to me?

and have you dynoed or ur just guessing by feel that your making power all the way up the band?

 

have the dyno sheets.
