need some info with u VE people.

i have a custom ARIAS piston that was design to my bluebird det converting to N/A with :
12.5.1 CR,86.5mm bore with deep valve relief on pistons to give clearance on valves, what would be the CR if i put this on a 20ve motor?? and how bout put the whole DET block with 20ve head?

i have some parts left i have that i was goin to use to build an N/A det,can u guys tell me if i should use them or useless or i dont needed to.....

arias pistons as said above ^^^
eagle h beam rods
arp head studs
det 8CW crank knifeedge and balanced,micropolished(was grinded due to have some scratched on journals [dont know how much of thous inch]not sure
u13 det block bored and honed for 86.5mm,cleaned and ready to get build

i was goin to build this thing but changed of plan,instead im goin for 20ve swap,i been in turbo for a long time and i gave up on this(got bored of boost:tongue: )
this is goin on my 91 ser daily driver.

apologized on long thread..hope i can get some help on u guys,thnx in advanced:biggthump

what's the stock de head volume (cc)?

 

[SR20Turbofreak]

nevermind

 

[kyoshoboy]

wow 14.4.1 cr that pretty high for a street car with 91oct pump pee:squint:
can i get away with it by putting a big cams on this compression?
need to know if i should do it or leave my vvl as is(stock block)and build the head?

14.4:1 is methanol territory really.

thnx for chiming in guys...i guess ill just leave my ve stock for the mean time....

Or put it in a DE or DET bottom end for the lower compression ratio....?

Chris

i think it would be the same or itll be lower but not that much i guess,,someone correct me if im wrong..

 

[zerogravity]

Dennis, if you put a DE bottom end with those pistons, it will be between 11.8-1 to 12-1 compression.

huh??? its the pistons and an 86 mm stroke with a VE head that makes it 14+:1

Mike

 

[kyoshoboy]

thats wat i thinkin too ^^^







but if zerogravity is right(hopefully) i prolly do it then if its goin to be that range of CR..

 

[SR20Turbofreak]

nevermind

 

[OnyxEros]

a 12.5CR 86.5mm DE piston (87mm head gasket) will = 13.75CR in a sr20VE

If the cc of the DE is 46

If the cc is 48 then the it will be 14.43CR in a SR20VE

 

[kyoshoboy]

i guess my ill be sellin the 12.5.1 cr de pistons,i cant use it on my 20ve,its too high for my needs.

thnx for help VE people for the inputs..



MY sr20ve is coming tommorow morning!!!im excited!
