Higher Compression

[TheAznPersuazun]

what are the procedures to get higher compression in my D16Y8....can i just put on a thinner head gasket or what?!?!?

[rubix777]

get higher compression pistons

[civickiller]

higher comp pistons, thinner headgasket, shaving the head and block, valves

[TheAznPersuazun]

say i didn't wanna spend the $ on internals cuz the turbo i'm getting comes with everything...would i still be able to put on a thinner head gasket or would i HAFTA get the pistons and cam?!?

[Tranzlogic]

the turbo your getting is comming with internals ??? and you dont wanna raise your compression if your going boost anyways..what turbo kit is this..cause that will depend on the boost variables and how much bosot you plan on running and so forth..shoot more info

valves huh?

[TheAznPersuazun]

well i kno i would only be able to run 5-7max boost so i've only put on it so far was plugs, wires, cold air, pulleys, and ground wires....i'm trying to do things i wouldnt hafta change or get rid of. So i was thinking of getting a Greddy turbo kit...what do u think?

Oh really? What kit is this that comes with internals?

Do you want to blow your shit up? Raising compression then forcing boost on top of that is retarded 'cuz'.

Got news for ya, the turbo replaces your cold air intake.

[civickiller]

yes valves that can increase your compression alittle, not much but just alittle.

you dont need aftermarket wires, oem honda wires are good. some guys running 500whp run honda oem wires.

you wont need any internals with 5-7 psi, i would just recommend a good engine management system

[TheAznPersuazun]

im aware that the kit would replace my cold air, but that's about the only thing that i would hafta worry about getting rid of...which wouldn't be hard.

[Tranzlogic]

well what do you want !? high compression or a turbo ? you cant have both on the engine itself..rather high compression all motor or low compression turbo for the turbo will raise....theres allt his talk about high comp pistons and then talk on turbo kits...which is it ?

Valves don't increase your compression stunna. The size of the reliefs can possibly affect it in minute ways that can only be calculated in a .000 addition to the rest of the volume calculation. Valves can affect compression test as in if they aren't seated right, air can slip by, but not what he is talking about.

im plannin on turboin my lude si with comp 9.6:1 stock, but most aftermarket pistons for the h23 come only in 9:1 and 10:1. id like to change over to the 10:1 pistons simply because i am doin all my internals( sleeves, pistons, rods, valves, retainers, valve springs) as one step and then later i will complete the car with the turbo setup. i would rather not lose .6 compression for 4 to 6 months while ordering and finding necessary turbo parts. Could i safely run 10:1 on say 12 lbs of boost with all the internal work already completed?
thanks

[SenseiAccord]

to tell u the truth... running 10:1 with turbo is not a good idea. If u want more boost... bare with the low comp for tat 4-6 month period and then when ur turbo is in... u have the rest of the cars life to have fun with. i'd say with 10:1 comp... u wont be able to run more than 8 lbs unless u use racing gas.

oh so i am wrong huh, ever heard of skunk2 high compression flat valves ? but thanks for clearing it up, im glad to find out that im wrong.

ok so valves have alittle dip in them, but with these valves, there is no dip and its all flat so therefore it raises your compression.

please dont talk if you dont know what your talking about.

you can run 10 cr you just need a really good tune and keep your eye or ear open for knock. but runnin higher compression will make your max boost lower. you can run more then 8psi, i seen type r's running 8 psi on there 11.5 cr.
