right now im running a b18a1 with a b18b1 head with crower stage 1 cams and valvetrain,blox intake manifold, golden eagle fuel rail, stock throttle body,cold air intake, jdm 4-1 header 2.5" collector, stock injectors, chipped pr4 ecu with basemap(not tuned), b16 tranny, 12.5lb flywheel, and zex dry nitrous 75 shot. i just ordered a exospeed stage 3 head that ported and polished, supertech valvetrain, stainless steel swirl polished valves, brian crower stage 2 cams, blox 70 mm throttle body, and im trying to figure out what pistons and rods to buy for the motor. i want to go high compression but still spray the car. does anyone have any suggestion on a piston rod combo and what compression ratio? also i plan on getting a obx lsd and a set of stage 2 axles.any suggestions will help

 

noone?

 

cheap *** eagle rods will do anything it sounds like you want to do. as far as pistons, there are tons of options. you can do in the 10s:1 on pump and probably mid 11s:1 on 110 or better with a tune. i really like the Mahle piston kits. many dont, but i have had great success with them boosted and in sprayed applications. they are pretty cheap, skirts are coated etc. they only offer a few comp ratios is the problem

 

Any forged piston such as JE, wiseco, CP ect. will do fine with a set of eagle rods or something similar. i'm currently running JE 11:1's with stock rods that are shotpeened with arp rod bolts for the past 3 years. This motor has been on a "100 shot" on 93 octane for quite some time going through endless bottles. i plan on putting bigger jets in to make a true 100whp more on spray since my motor seems to love it and has shown no sides of being hurt.

 

ok thanks for the info what times are you seeing with the 100 shot

 

Don't worry about the nitrous; just build it as if you were doing a normal aggressive NA motor. It will love the spray if you tune it right.

 

ok, here a question i too am going the nitrous route, and i have a Ls/vtec with factory ITR pistons, are the factory pistons ok for a 100 shot?
