Alright guys just got my project done....Its a 93 civic hatch with a d16z6

Setup is

Garrett Super 60 turbo gated at 11psi...
HF manifold with adaptor plate
DSM 450'cc injectors
apexi FMIC
2'5 Inch FMIC piping
3" Inch Turbo back exhaust
ARP head studs
And bone stock top and bottom end..

Car made 236HP and 200TQ
Street wideband tuned with cromepro.....
My Question is wanna do a little upgrade with the Manifold and run a tubular....Does this mean i will need to retune my car or should I be fine just changing them out

Also I'm going to install a boost controller and turn the boost down to about 7 or 8 psi....Until I can go all out on the bottom end.... So my question here is would I need a retune in this situation if I turned down the boost


Any help at all would be great....Have searched but may have over looked sorry if this may be a repost.....

 

post some pics of the setup then we can discuss your problems

 

boost controller ain't gonna turn the boost down to 7 psi if WG is set at 11 psi (it has to be lower than @ BC imho )

 

O ok that was another thing i was unsure on but if I run the tubular mani I will upgrade to external wastegate....

 

most external WG's come with a few different rated springs that very. as far as having to re-tune no its not going to be n issue.

 

Here are a few pics
