I have a turbo with a t3 flange and am planning on buying an hks manifold for my 99. The hks manifold has a t25 flange. Will my turbo bolt up to the manifold?

 

no, unfortunatly not
t25 differs from a t3 flange, grab a manifold from begi

 

since the HKS manifold is a top mount for the turbine, adding an adapter plate, or even welding one one will position the turbo way too high.

Go with the BEGi manifold, or even the ETD Racing one.

 

Yep your turbo will pop out your hood with the hks manifold, this guy made the same mistake lmfao.

 

Holy phuq!

What they said, get the Begi mani.

funny thing is, his junx is turbocharged already, mr. parts-collector.

 

eh Come now, Im close

 

WOOHOO!!!! I love those pictures!!! There's an entire video of that chick photoshopped into all sorts of crazy poses!

And yes, do not buy an HKS mani for a T25. The only way to mate it up is to use an adapter like the one here: http://cgi.ebay.com/SR20DET-T25-T28-...QQcmdZViewItem
As said before, this will have your turbo sticking out the hood. Scrap the entire idea completely. Get a Begi manifold and sleep soundly at night knowing you've bought the best on the market. Yes, it's a bit more money, but this is the one piece of your kit you do not want to skimp. More people have more problems with manifolds than anything else when they cheap out.
