DeltaNu1142 Posted January 3, 2013 Share Posted January 3, 2013 I'm starting this thread because I've just bought a VF52 and a Process West TMIC, and I'm wondering if I should also consider an intake. I intend to keep this as a DD and I'm not considering fueling mods unless something fails. I'd like to hear from anyone at stage 3 who still has their stock intake, and from those that upgraded the intake after going stage 3 because the intake was restrictive (or some other reason). I'm obviously looking to make a decision before getting tuned. I've read fahr_side's very helpful thread here in preparation. Tits mcgee Link to comment Share on other sites More sharing options...
I Donated Too laff79 Posted January 3, 2013 I Donated Too Share Posted January 3, 2013 I would use the money for a fuel pump instead of the intake. Stock is fine I believe. Link to comment Share on other sites More sharing options...
ripemeat Posted January 3, 2013 Share Posted January 3, 2013 o_0 stock intake. DW65c fuel pump. Link to comment Share on other sites More sharing options...
DeltaNu1142 Posted January 3, 2013 Author Share Posted January 3, 2013 Got it... I shouldn't need the pump prior to tuning, though... right? I'll just be operating at the upper limits if the stock pump...? Tits mcgee Link to comment Share on other sites More sharing options...
Moderators BarManBean Posted January 3, 2013 Moderators Share Posted January 3, 2013 agree with above. you say you don't want to replace fuel items unless they go bad, but if your stock pump goes bad because it's getting beat on it's possibly going to take your shortblock with it--leaning out at high power levels = no bueno. "Bullet-proof" your OEM TMIC! <<Buy your kit here>> Not currently in stock Link to comment Share on other sites More sharing options...

Ah, so. Infamous offers a stage 3 tune w/o fueling mods, but I don't know whether that's injectors only. In either case, I don't want to be running lean. I'll look for a pump... typically you install mods before tuning OOOOHHHHHHHHHH... Tits mcgee Link to comment Share on other sites More sharing options...
fahr_side Posted January 3, 2013 Share Posted January 3, 2013 If you've read my thread, you know the answer. Stock intake can support much higher flow than the VF-52 can manage. Fuel pump will have a hard time keeping fuel pressure up at the sort of IDC the airflow will demand, especially in the long-term. Obligatory '[URL="http://legacygt.com/forums/showthread.php/2008-gh8-238668.html?t=238668"]build thread[/URL]' Increased capacity to 2.7 liters, still turbo, but no longer need spark plugs.

ripemeat Posted January 3, 2013 Share Posted January 3, 2013 There's no such thing as bigger injectors on stock fuel pump you get a better pump to maintain fuel pressure at higher psi and rpms so you don't lean out. the 52 has been shown to need this since it flows more, without it, you'll be leaving power on the table- that's for certain.

I wanted input from others who may have made a change for their own reasons. If the only reason is noise, I'll keep it stock. Tits mcgee Link to comment Share on other sites More sharing options...

DeltaNu1142 Posted January 3, 2013 Author Share Posted January 3, 2013 Closing thread... I got the answer I was looking for & showed my thanks... anything beyond that isn't helpful. Tits mcgee Link to comment Share on other sites More sharing options...
