... curious what people suggest... i am definately gonna go with forged internals... just not sure if the $800+ for sleeving is worth it or if it should go to headwork instead... lemme know what you think... thanks...

Block without a doubt. A lot of people are making huge power on a stock head, all you really need in there is some valvesprings and you're set.

Block is more important. That's whatholds the boost, and stock sleeves are fit for such pressure's.

speedymon

The block. It holds the boost and takes the wear and tear of boost.

I would deffinatlly sleeve it and go ahead and run 83 or 84mm pistons. With a sleeved block you can make 450whp safley but you can't with stock sleeves and a ported head. I know some people have but it won't last long driving everyday.

definately go for the bottom end, stock honda sleeves will crack and then you will be shelling out a ton of $$$$. do it right the first time and RESEARCH!!

TurboTegB18c

Yes, sleeves first. Headwork can always be done later on. While your redoing the bottom end, you should go ahead and do the sleeves too. It'll save you in the future. Paul

Def. sleeve the block first. Unless you are one of these guys that is going to pul off 22psi on a stock block, it is the best bet.

Block.....And a good set of valve springs and retainers..Do it right the first time...It's much more expensive the 2nd time you have to do it!

Don't get retainers. They really are not needed. Just causes reliabiity issues.

SiRkid

sleeved for sure.

How much boost can you run safely with stock sleeves????

like what? i have full ferriea valvetrain, including tit. retainers. some say they wear quicker, some say they last longer.?

and defentially the block first

BudaKai

How can someone say an element with at least twice the wear resistance of the stock ones can wear faster? I think someone has been spreading lies again. I think your mistake because it's the stainless-steel valves that wear out the valve guides quicker. That's why you buy the trick alloy ones with magnesium in them.

I have a gsr head that used to be really nice....now junk from a stock retainer that broke in 2....So do what you will...Just trying to save someone money from a lesson I learned the expensive way.

Are ITR springs and retainers worth upgrading to or are they even worth while for 8500rpm and 450-500whp?

Quick 200k Mile Motor

I have crower 87091's made to fit Honda springs ..titanium 6 grams each and lighter than skunk2 retainers. I figured since these are lighter and stronger than stock it will be more reliable. Anything bad about crower retainers?
I know that springs might "dig". I can probably prevent that by deburring/chamfering the inner & outer of the inner & outer springs.

2K_TEG

Stock Honda retainers are designed to last forever. I have seen a few Hondas in the 300K mile mark. There is some website somewhere that keeps track of that.

Anyways, arguing that OEM is not built to last is ridiculous. The problem with titanium retainers is their wear. It is FACT that titanium retainers will wear out and need to be replaced. Most of the companies that make titanium retainers suggest that you check your titanium retainers and replace them if necessary every 10-15K miles.

Do a search in the ITR forum and find all the guys who have very worn, or even broken titanium retainers resulting in all sorts of damage.

If you are really worried about the extra weigh, go ahead and spend $160 or so on retainers and get ready to check them often. Cause I know I would be paranoid with them in my car.

So... How much boost can you run safely with stock sleeves????

SiRkid

yes.. im not sure if itr retainers are diff but the springs ....
if you have a b16a2 all you need is the itr intake side . you take your intake side(same as itr exh) and move that to your exhaust side and put the itr intake on your intake side.

LS-hatch

it all depends on which motor and how well its tuned. There are people who push 12 psi daily on stock LS blocks. It all boils down to TUNING. Tune it right and dont give in the to urge to turn up the boost just a little more every now and then, and you should be fine.

hybrid901

I have been running 18psi daily on stock gsr sleeves but I do have a backup car. I would say 10-14psi is safe tuned properly.

I have a extra set of itr springs and retainers. Will they be plenty or should I upgrade? Are teh ITR lost motion assembly needed?

Speedworks801

I'm sure it's already been said twenty times, but

SPEND THE MONEY ON THE BLOCK!!!
