will getting the hondata k pro increase the chances of blowing my motor?

G-Ray · 11-19-2007, 09:19 AM

itll make vtec kick in @ 4500 n redline to 8700. would having this upgrade be costly in the long run or better yet damaging?? im considering getting it but i also plan on keeping my fa5 a long time

***k20z3 Koop*** · 11-19-2007, 09:21 AM

I think you mean the reflash (K-pro isn't available for our cars)

To answer your question; people seem to be having very good luck with it... I plan on getting it in the spring myself.

Search around people seem to love it

Edit - Also its 8600 RPM not 8700.

rbsjnh · 11-19-2007, 09:29 AM

the motor will last as long, just don't mis-shift or you will bounce a valve..

G-Ray · 11-19-2007, 09:35 AM

so to be on the safe side upgrade to better valves u would reccomend??

***k20z3 Koop*** · 11-19-2007, 09:38 AM

Valves don't stop you from floating. Its the springs, if the springs are too soft and over compress the locks (AKA keepers) holding the valve in can come out. This would make the vale no longer connected to the spring hence 'floating' around. not to mention the locks could fall into the cylinder...yuck.

It's not worth upgrading valve train for the reflash. IMO, if you're going that far wait for Kpro and do cams.

rbsjnh · 11-19-2007, 09:39 AM

no leave the valves alone...no matter what quality valves you use...you can still bounce them...the reflash mainly works on the vtc...the cam advance angles...by advancing the camangles, the valves are closer to the pistons, if you misshift, contact will be made...get the reflash...just be careful

**Nomar06** · 11-19-2007, 09:39 AM

doesnt really matter. If you miss shift now you still can damage valves.

I agree, but the stock valve springs are good enough for most that we do...unless full race apps.

^yea thats what i said

Waiting... Any ideas when?

***k20z3 Koop*** · 11-19-2007, 02:51 PM

edit, should have read what you said. hahah I thought you said 'then' not 'when'

I've heard/read a ton of things... some say early 08'

we'll see

So far k-pro will not be available for our cars be it fa5 or fg2. Hondata will not comment on their products in the making. The reflash is a fantastic upgrade and is perfectly safe to use on your car as long as you have at least an intake and exhaust or header. In the past hondata has applied discounts to those who purchased a reflash and then switched to the kpro so if they come out with something they might do this. The valvetrain is quite competant from the factory. The k20 has one of the highest piston speeds of any factory vehicle on the market so you can bet their springs and retainers are very good quality for oem. I would imagine anything over 8800 to 9000 would require a stiffer spring and titanium retainer.

***7002iSciviC*** · 11-19-2007, 05:26 PM

just dont get it if you really dont race very often no point of getting it. thats my oppinion, i bought my 07 si for the looks and it can do alot more compare to other car with its retail value and its honda

guaranteed to last forever, if you dont abuse it

ThatsMrGimp2U · 11-19-2007, 06:03 PM

I thought it was noted on the hondata main page that floating didnt occur on the z3 until about 10000 rpm.

Would powershifting still be okay?

shutter13 · 11-19-2007, 07:36 PM

for everyday driving just dont be bouncing off the limiter to be safe... but our engine can handle the high revs with ease

***jdmEGO*** · 11-19-2007, 07:38 PM

^^^ powershift is okay if you do it right, but you will burn the clutch.

ThatsMrGimp2U · 11-19-2007, 08:24 PM

Thought as much, just one of those "use responsibly" things.

yourwhiteshadow · 11-20-2007, 04:41 AM

i remember hondata saying its better to have an 8600 rpm redline than 8200 and hitting the rev limiter.

eulbijif · 11-20-2007, 08:19 PM

i can gurantee you that if you rev your car to 10k on stock valve springs you will bend valves stock valve springs dont have enought pressure to keep from floating . also i dont see any k20 with stock cams making power above 8400 no need to rev that high by the way if you do bend valves honda will not cover the damage!!

ThatsMrGimp2U · 11-20-2007, 10:22 PM

Quoted from Hondata:

Will this affect my warranty?

Any increase in RPM limit is at your own risk. If you suffer engine damage that is related to excessive revs Honda / Acura will not cover your warranty. Valve-piston contact, which typically occurs at 10,000 RPM is the result of a miss-shift.
