[ZZZcb7ZZZ]

hello
thank you for reading mine first of all...

i ordered NOS Sneeky pete just now for b16a2... to satisfy my HP addiction...
i know i got to get motor COMP. check...
get my sparks replace w/colder ones..
i m not gonna go more than 50shots for while and
i have stock Fuel-Injectors... should i get bigger ones to Balance A/F ratio?

meanwhile since i will be getting Funny gas in 5-7 days,
i was thinking of replacing all the hoses under the hood...

my plan is that, i m just going to get matching hoses from autozone and start replacing them

is there anything i should know about b4 i do that..?
any vacumm Comp. isues i sholw know about..?
should i get motor oilcooler..?

any input would be thankfull
thank you
