Rb30et To Rb30det

[shakotan-cefiro]

hey guys

.

i read through most of the rb30 conversion thread and i have some questions please help if you can

i have a rebuilt forged rb30et and a r32 rb25de non vct head

i plan on building a 25/30

how can i increase compression from the horribly low comp if i just combine the two

idealy id like around 8.5:1

i am doing all the work myself except the machining so i need to know what to tell the workshop

thanks heaps

also guys as the engine has forged intenals i want to avoid changing the pistons how much can i take off the head and block???

need to swap pistons to increase the CR to a respectable level mate, the general consensus is to run rb30e pistons to achieve roughly the CR your looking for.

a few manufacturers actually make pistons for rb30det conversions with CRs around the 9 mark, that would be the ticket IMHO
