So I'm thinking of going turbo with my D16y8 in a 89 Si hatch.

Im curious to know if the T3 is a good start turbo for stock internals?

Which t3 would be best for me the 42/48 or the 60/48?

What are the stock psi on those turbos?

Should I go to the 14b?

Whats the stock psi on the 14b?

What diameter charge pipes should I run?

Thanks for the help guys

 

go w/ the 14b if ur gonna keep stock internals.... it spools fast..... internal wg set @ 10 psi (fully open)

built block.... t3 48/60 or t3/4

 

woudln't 10 psi be a bit high for stock internal?

 

Where did you get your manifold and downpipe?

What size charge pipes are you running?

Any hp/tq #?

Thanks man

 

get a t3 42/48

 

t3 42/48 seems to be the leader.

Where might i be able to purchase an adapter plate for the t3 to use with the STD manifold?

OMG... not this again!!!!!
ok... i tested the wastegate on the turbo w/ compressed air w/ a regulator and a gauge... it starts to open at 8 and is fully open at 10.

for the adapter plate.... BMC sticky in the for sale section has them.... good quality!

in your opion is 10 psi to much to run on stock internals

i will have injectors, fuel pump, fpr, hondata

 

run it... if your unsure about 10 psi you could alwas get a different WG w/ a lower psi rating!

if u got hondata.... i wouldn't worry bout it... just tune the hell out of it!
