I have a jdm b18c gsr and I recently fried my rings. I was making 300whp and 190wtq on the stock motor with ITR cams. since im gonna have to tear down the motor I was wondering your guys input on a nice set of pistons and rods. since my motor will be built after this I will be shooting for 400whp realible because its my daily driver. Im leaning towards golden eagle rods. because ive only heard good things. my main question is pistons. Ive heard some pistons get valve slap while warming up? should I lower my compression ratio or keep it the same? im not going to sleeve the block either

Im gonna also get ARP head studs and Probably Rod bolts. any input would help

Engine setup is Garret 60-1 Turbo, big intercooler 3inch core, Walbro 255, 560cc injectors, Crome Tuned, ITR cams and Skunk2 manifold.

 

bump no suggestions on pistons?

 

Wiseco Pistons - Eagle Rods Best bang for the buck IMO

 

What he said. 9.1:1 should be good enough, and will be on the safer side for a daily driver.

You might want to look into bigger injectors as well.

 

yeah I was wondering about my injectors I cant remember the duty cylce from when it was tuned

 

what about these?

I would personally go with Manley Turbo tuff rods & CP 9:1 or 9.8:1 compression pistons.

Make sure when you tear all this down you freshen up the block as well. Do a final bore & hone to clear out any imperfections in your block and make sure they hone the motor so you can properly break in the piston rings. The proper way to size the pistons as well is to let the machine shop do the final bore and hone so you can match the size of the piston to the block. They may have to take off a bit of material to straighten out he block so I would wait and order the pistons after the machine work has been done. Make sure while the block is out that you get all new bearings and check out all the components internally in the motor, normally its also a good idea to go ahead and change out the oil pump while you have the motor dis assembled.

 

ya eagle rods will work fine and pretty much any brand piston.. wiseco, srp, ross, je, aries....exc.... i had aries on my dd and they were fine till a injector seized and it melted a hole the size of a quarter in the piston.. lol

 

560's will get you almost to 400whp with CRAZY fuel pressure and a stellar engine/turbo combo. Otherwise 650cc is the minumum, >750cc would be recomended.

Properly clearanced Eagles/acls will work fine, as well as any from Wiseco/CP/Arias/JE. SRPs are the only iffy piston due to the way the material expands. I have no issues with daily driving my WIseco/eagle setup, running .0038" piston clearance. FYI the coated Wisecos 'gain' another .0003" or so after break-in. The embeded part of the coating remains, and still acts as lube.

 

good to know guys thanks for all the input and yes I have a brand new oil pump and water pump and all that other good stuff ready to go.

 

i agree with everything you said but that ^^

always go with a .20 overbore

and always have the pistons there so the machine shop can number the pistons to each cylinder as every piston will not be the exact same width (although cp have always been as close as it gets for me)

 

Running SRP's with scat rods. love'em 9500rpm 16 psi pump gas not a single problem in a 89mm stroked GSR

 

^ do you know where i can get srp piston rings?

 

yea you should look into at least 650cc for anytihng over 400 whp
my supra is making 386 on 550s and its at 90% dc towards the top end

 

JE makes SRP pistons so just get JE rings
