Whats the best brand of pistons to go with for a turboed type r. With stock bore size. Sc61 wanna make 450whp

 

cp, arias, je, wiseco, endyn, ross, pick one. all are great. i have used srp, je, and currently cp.

 

i use nothing but wiseco's in all my cars

 

that's like saying what kind of socks are best, Fruit Of the Loom, Hanes, Nike, Reebok,...

 

I run arias

 

I've always had great luck with srp's and JE's, but like stated forged anything will be better than stock. Also just go with stock bore if it doesnt need to be machined, but if it does just go with the standard .20 over to 81.50mm. Displacement is less important when you start to go with boosted applications imo so just go with whatever ya already got

 

Isn't stock 81mm? So wouldn't .20 over be 81.20mm not 81.50mm?

 

No, he probably meant .020", which is ~ .5mm

Any name brand of piston installed appropriately should perform just fine for you. This means that you should make sure your cylinders are within spec for the pistons you want to use. For the best results, do it the right way and pull the block and get it machined with oversized pistons.

 

There really isn't a "best" piston. Its generally preference

 

Ahh I see. Thanks

 

Thanks guys, i didnt really mean best piston, just wanted to get some pros and cons.

 

Nike FTW!!!

 

Okay I'm confused. I'm buying a b18c R that's been bored out 20 over. Does that make is a 81.2mm?

I need to know cause I wanna Turbo this block and make sure I have lower c/r

And if the size of the engine is 20 over what size pistons do I need? How much clearance does the piston need from the block?

 

As quoted above you need to make sure if youre talking about inches or mm's. You probably have .020" over, which is .5mm. That's a standard bore for stock sleeves. You'll need 81.5mm pistons. Piston to wall clearance depends on the pistons and brand you get, the power you're going to run and if they're high or low silicon. For example my Arias pistons are at .0040 but im at 490whp. Are you going to run E85?

 

cant go wrong with what you pick. I have 81.5 Wiseco pistons in my car, I couldve gotten CP for around the same price.

 

i was planning on running at least 400hp

but i havent even looked into running E85

I need to lower the compression rate to at least 9:1 and i wasnt sure what pistons to get for 81.5mm i dont want to much grinding. Ill prolly have to sleeve it for extra protection. But im not even sure how to do that.

lol I hatez bein n00b =/

 

You have some reading to do. Do not go less than 9:1. If you run 91 octane run closer to 9.5 and with E85 go to 10:1. What do you mean by grinding? Pistons don't grind... Sleeving too? If you sleeve the block, your current bore doesnt matter. If you sleeve it go to at least 83mm. Try the search function

 

lol

Wow I just proved my N00b skills.

I didnt mean grinding. I meant like the wear on the block from friction. I was told I should have it sleeved with benson. And I had no idea that sleeved kits were that much bigger. Prolly why the can take more turbo cause of the lower compression rate.

What are the benefits of E85? cause you seem very supportive of it. lol

 

You won't wear the sleeves much unless your piston to wall clearance is horribly off. Keep in mind aftermarket sleeves are cast iron... not aluminum. You can have a little piston slap when cold but this normally goes away when the engine warms because most forge pistons expand. When you buy pistons they come with install guidelines for your machine shop that include PTW clearance. All you need to do is buy the right bore. Some people go to 85mm on their sleeved blocks (84 is most common).

Summer blend E85 is 105 ocatane or so. Clearly much better than 91... With the right fuel set up you could get 1200whp out of E85 on a 4 banger

 

So for E85 I just have to buy the EFI's for it correct?

 

For any 450hp honda motor you're going to need a new fuel pump and injectors (larger injectors for E85 because you need 30% more fuel). Fuel lines, rail, filter and pressure regulator are all ok stock. When you replace the needed parts you can run any fuel you want, 91/93 octane, E85, E98, C16, Q16, etc...

 

So i found a set of pistons on JE

they are $671 for the whole set and they lower the compression ratio to 9:1

Nice!

Too bad it doesnt tell me whether or not it comes with or if I need
Retaining clips
piston pins

Im assuming I would need 4 of each item?

Dont spend $700 and buy them off JE's site, you can get CP's for way less than that.


They also have JE's if you're set on that brand.

So the JE 9.0:1 81.5mm pistons are listed as part # 188982 so you call RSP and tell them the part number you want etc. That comes with the wrist pins, the pin locks, and the piston rings.

 

Yeah that's too much. You can get Arias off their site for $595 and that comes with everything you need. If you're okay with spending $600 I'd go with CP

 

Hell yeah

I appreciate that Itslogs

I about to order those..........Now!
