whats the highest and safest redline point that a stock block GSR can be revved up to before damage such as throwing a rod or anything sudden is more likely to occur. My car is in the shop now to get some head work and the shop recormended me getting their valve train(titanium retainers and springs). I know this will allow the head to take a beyond stock rev limit shift, but what will my bottem end be able to handle safely. I am very hard set on not damaging my motor after I get it back because im pushing my budget as it is just to get the work done now and throwing a rod or somthing cause of to high of a shift is the last thing i need. Also what could be another advantage of having titanium valve springs and retainers?

valve train(titanium retainers

what brand are they or are they custon valve trains??

i would just get some brand name aftermarket valve train if u going to upgrade them
like skunk2

i take mine to 7600, anything after that isnt producing enough horsepower, 7500 to be safe

i'm sure if he's getting head work he should be able to take it higher than 7500. stock redline is 8200. just make sure its tuned before you try to take it any higher than stock

heya i had a gsr block with ctr pistons and stage 2 cams. I had valvetrain of course, and i revved to 8500 all day long and 9000 VERY few times and ha dno problems for 13K miles. Im going to do the same thing, i have stage 2's sittin in my garage, there about to go into my gsr motor and im gonna take it to 8500. it's not too much over stock 8200 but larger cam so yea I think the problem would actually be the rod bolts or the bearings. i think the rods are strong enough to hand 8500 so if anyone knows?

Just don't go to 10,000, your car can't handle the extra digit.

BLK99VTECR

so 8,500 sounds like the safe point

it depends. no point in revving that high if it doesn't make power up there anyways.

yea I know that, but beyond where a motor stops making power in the head there has to be a danger point that the stock rods in the bottem end cant handle if there is.

timisyourfriend

if your motor is completely stock, then don't rev higher than what the stock gsr revs at. Honda made it redline for a reason, they wouldn't stop the engine at it's power range. shift at 8200, trust me, 8500 if you have many bolt ons..

BLK99VTECR

geez, the head is not going to be stock. only the block is going to be.

Dueceification

It can take atleast 8500 safely, plus your upgrading your springs and retainers so i'd say no more then 9k. I used to rev my stock b18c1 to 8500 all day with no problems and i also brought my stock b16 to 9000 with out any problems either but only did that once or twice. As well with my b16a motor.

timisyourfriend

valve springs, retainers, cams, and your basic bolt ons (i,h, e) then I'd do 8500 all day. (= get a vafc and tune that sucka.

honda011

if ur werking ur head get it tuned then u should know... if its a stock gsr i tok mines to (when racing) and its been fine... too lazy to read lol

If all you are trying to ask if "what can a stock bottom end handle" then the answer is ~9,000rpms. Personally, with stock rod bolts, I would not go beyond 9,000rpms.

ok cool, im trying to get some stage 2 skunks right now to replace the CTR cam thats they gonna install cause i know the skunks will probally make more power beyong 8200. I got a V-afc, FRP cam gears but im probally still gonna try to get hondata when i dyno.

Punker1234

Hondata. GET it. im doing the same thing, i went fmor a buitl motor to a b18c with stage 2's for reliability. but honda will make u a good amount of hp from stage 2's alone. My budyd made 170 whp with stage 2's on a b16 with 120,000 miles on it and basic i/h/e. nothing bad ***, but about 40 whp voer stock

Skunk2 Stage 2's on stock GSR compression will not be impressive. But each to his own.

Punker1234

i realize, i have ctr's untunde, but eveyrone is telling me i will still make more power with stage 2's... i get mixed info for everyone haha

Then you obviously haven't done the correct research regarding those cams. Put them in if you want... Tuned, those CTR cams will be better at stock compression levels. Tossing any cam in and not tunning it and then saying "brand X will make more power" is just plain rediculous.

i agree.... might i suggest skunk stg one's?

Punker1234

well i have stage 2's sitting int he garage, and i have hondata. so ur saying the ctrs will make more power regardless, tuned with hondata?

Nevermind. Its obvious your mind is made up. Go put them in. Don't forget to upgrade the valvetrain also while you are at it.

I have a JDM GSR with high compression than the USDM. My head is getting ported milled and a valve job wit up gradded valvetrain and in the end my compression should be 10.8. should skunk2 stage2 out perform a CTR intake cam drop in with the same head ?

ohh good, compression. thats what stgII's need.... but to my understanding, you may want something above 11.0 for those cams... there will be some who will tell you that you need something higher, and some who will tell you that its fine...

IMO, if you got a good tuner, he'll be able to work it out....
