That's my goal I figure I'm going to need the following:



Intake

Header

Exhaust

High Flow Cat

Full Synthetics All Around

Upgrade Spark Plugs Wires/ Reground major grounds

ECU (pocket logger or Apexi SAFC)

Clutch

Flywheel

?light drive shaft?





Any other things I could do? (besides porting, want to avoid taking the engine out/apart)

87 S4 BTW



I figure low 15's or high 14's with that much hp. @ <2600 lbs.

vosko

if you do 170 with just that. i will be impressed

Rotary_Engaged

Lol, That's why I'm asking I know I'm missing a few things. Like emissions removal, TB mod, S5 intake manifold, an intake manifold insulator etc.



Or I could go the "Lazy" route and just drop in a 13b-T.

vosko

well how much do you want ? its much easier to make power 13bt



n/a costs alot!

Rotary_Engaged

roughtly 170whp or 190-200 flywheel hp.



If I can do 160whp with what I listed that should be sufficient as well.

vosko

dont think so, but you can try

Leetheslacker

s4?



throw some stock turbo **** on it and boost it.



trust me, its worth it.

Rotary_Engaged

I thought that was a bad idea because of differences between the N/A and turbo engines? Something about compression and stuff...

Leetheslacker

s4 na has relatively low compression. gotta keep the tune rich for safety, atleast i am.



but really, port a tii lim, and then everything bolts on and plugs right in. easy peasy.

j9fd3s

i dont know about s4, i think you're down 10-15hp over an s5.



i have a customer with an s5 na, intake, header, catback, gtus rear end, and vert rims, it runs high 14's....
