I am looking for suggestions on what a good piston would be for a GSR Block that will see most likely no more than 15lb of boost. My main concern is that they are not a full race piston as in my experience clack around a lot. I want an stock to almost stock sounding piston if thats possible that can handle some boost.

Also what is the latest greatest block gaurd? and what do you have to do to install one. thanks!!!

I'm not a newb just an oldie that is getting the bug again.

 

Go with a set of CP's or Wisecos....ditch the block guard idea

 

What are block gaurds no longer the trend? I see these dramatic sleeved blocks and dart/erl blocks but the prices are outside what I want to spend right now. Should I do anything with the cylinders?

 

Most people, myself included, just rock the stock sleeves unsupported. I think its an accepted fact now that block guards really dont do anything other than stop the sleeves from rocking at higher rpm...they wont prevent cracking due to detonation. If your tuner is competent, you shouldn't have to worry. I'm shooting for 450-470whp and i'm not even going to consider a block guard. I'd go either stock sleeves or consider sleeving if your budget allows...there's really no step in between.

 

9:1 CP's would be best choice, no block guard

 

I'm eyeing some wiseco 9:1's with eagle rods off of ebay, and shoot from there. And yeah I'm going with hondata and theres a ton of good local tuners I can choose from. It's nice that all of this stuff is so tried and tested.

 

One thing i would advise is to think about your compression ratio based on the fuel you plan to run and your power goals. Most people settle on 9:1 because its been done a thousand times over, but i know for my setup, i want to have similar response to stock when i'm out of boost; therefore, i opted for a higher static compression. This also is due in part to the availability of E85 in my area.

...just something to think about

 

9:1 is the most common choice. i'd go with that. You can also get a flat top 10:1, but its all preference.
All forged pistons are pretty much the same, meaning there isnt a "fullrace" piston that is off the shelf. and keep in mind piston slap in many cases are due to improper machining. Any piston, even an OEM piston can get piston slap if the block was machined wrong or it does not have the proper piston to wall clearance. Just keep that in mind.

Block guards are old news. at 15psi, you can do without it.

 

Yeah I have been out of this game for about 6-7 years but was pretty respected back in the "old days" hehe. I have actually considered putting compression up to around 10:1 because with the right tuning and decent valves etc. I had good luck with that years ago and you definately cook up some power noticably faster, but you can't run high boost obviously without race fuel. Thanks for the current/usefull info. What turbo/manifold/intercooler combo is a good streetable ball bearing setup? curently.

 

SRP are not "full race" pistons

 

Wiseco's 9:1 Here no problems Love Them

 

Wiseco seems to be the most recomended street piston, I think that's going to be it. With eagle rods and some decent tuning.

 

On our personal cars, we actually run 10.8:1 flat top pistons in 84mm. People are scared to go that high, but if you have a good tune, it shouldnt be a problem.

 

while I have your attention, what are some good turbo setups that I can still use AC/PS with? on a 97 integra. I see you are a dealer. It seems most people piece together there own but really how much are you saving and parts compatibility has to be a nightmare! esp. since I want to keep as much as I can (ps/AC) thanks
