Installed small 16g now have question

[StarDiamond]

I installed my small 16 g last night and i took it for a test run. Comparing it to the t25 it seems like it doesn't pull as hard from the bottom but does pull up top compared to the t-25. 1) people who are running the small 16g where do u have full bost (RPM), 2) how did it compare to your t-25 pulling on top and bottom, 3) i still have the stock downpipie and cat when putting my N1 downpipe with no cat will it make a huge diffrence in spool up time? Thanks for your help J

What you're feeling is pretty much correct. The 16G series will take longer to spool up than the T25, however there's much more room up top and the boost doesn't seem to run out as the motor approaches 7000+ RPM or so. It's all about efficiency range.

Typically, Small 16G's are fully spooled between ~3100-3300 RPM and Big 16G's are fully spooled between ~3200-3400 RPM. As you mentioned, exhaust will have something to do with spool time (the more free flowing the better) as will any port work done to the turbo. Also, while not necessary, some people opt for stainless or mild steel tubular manifolds that also help decrease spool time.

Hope that helps and enjoy your new turbo!

I had my small 16g installed with the slowboy's ported manifold dammm that thing had full boost @2800rpms. and pretty good top end, too

Yeah man, porting makes a big difference. Reminds me that I need to whip out the Dremel and carbide bit really soon.

A dremel, shit thats take years to port a 02 housing or a turbo.


anyway, i get full boost at about 3200-3300rpm and that 20psi, Small 16g after i put it on i didnt notice a huge difference down low and up top just pulled a tad harder. But after other upgrades its a little different now.

Also what other mods do you have to go with this 16g and what boost are you running?

my e16g reaches 15PSI at 3000RPM and starts spooling at 2400RPM

i used to own an 11 sec small 16g, i reached full boost at 2900 rpm, for you to realize the turbos potential down low and up top, you need a good/free flowing exhaust, intake of some sort(injen for example), k/n air filter, a 3in down pipe, front mount i/c, 550 injectors,afc, an egt gauge, zeitronix a/f meter, port the turbo, o2 and manifold, run some good race gas and tune that baby well, you should be able to rip into 12s easy and even 11s, with cams, 11s can be achieved easier, also you need to drive well. those mods should spool the turbo quickly and let you boost away

and it's a sad day in my life since i reach full boost only at about 5,000rpm wish i knew why.. i tried just about everything.

Marc,

I'm no pro, but it seems that serious boost leaks would contribute to a late spooling problem. Let us know what you've tried so that maybe we can recommend a few additional things to look in to. Have you tried disconnecting the MBC and see what she'll do (carefully of course)? Could be a bad wastegate arm as well.

Dang I hope that helps,

Andy

I just finished upgrading mine from the t25(mods in profile) and I reach full boost about about 3k.

My old set up was a fully ported small 16g, ported 1g o2 housing, and 3" turbo back, I reached 19PSI at about 2800 which is really good spool. Take advantage of the fast spool and open up your intake and exhaust.
