IC piping size - Honda Forum / Acura Forum

95accordlx · 08-29-2004, 05:14 PM

Im currently in the process of totally redoing my turbo setup.
T3 to T3 T04E 60 Trim
Starion IC to custom IC with 2.75" endtanks
Deltagate to Tial 38mm
TP mani to SFP tubular mani
2.5 " TP downpipe to custom 3" DP
2.25 exhaust to Kteller 3" setup with N1
DSM S-AFC setup to hondata S200 with 3 bar map

I was also running really skinny 2.25" ic piping. My question is, since i will be flowing that much more air...... i wanted to run 2.75 inch piping to the throttle body ...same as intercooler endtank. Will i suffer any adverse effects or will it benefit my setup?
Thanks in advance guys.

2.5'' would probably be easier to find but if u can do 2.75 go for it, u MAY see 1psi drop but that would be minimal and probably not noticable after u get the new setup retuned

I can get it from ATP turbo.... they have all the diff sizes. Im just wondering if im going to gain or lose by going with 2.75 piping from IC to TB.

my take is that u will not loose anything that would be noticable.

2.75 imo will be to big. no need for that unless your pushin 500+whp. 2.25 will be fine from turbo to i/c then 2.5 from i/c to tb. i went with 2.5in all the way around but my setup is a little different since my i/c piping is about 3ft long total.

if it were my car, id stick w/ the 2.25 piping

travizx0r · 09-01-2004, 08:13 AM

yeah id stick with the piping you have right now because its about the right size maybe 2.5. i think on my setup i will run 2.5 but because its easy to find piping and ect that size. and oh yeah the bigger the piping then more the lag.

Ok guys i decided on the 2.75 piping from IC to TB. I really couldnt find any hard evidence to support the claim of any kind of HP loss or major lag.
I figure my old piping was way too small and the new turbo is going to be pushing a lot more air so y not upgrade the piping size? I will let u guys know how it runs. If worse comes to worse i will downgrade to 2.5.
Thanx again guys.
