TPI porting
 

I'm looking to get my tpi SD vortec intake ported. I thought about doing it myself but I would rather not screw up a 400 dollar intake.


I've tried to contact High Flow fuel injection but no one responds to me.


Can someone please help me find someone who can do this for me? I dont want it to be some clown who thinks they know what they are doing and not get what I pay for.


Thanks

Honestly I'm not sure who to recommend. Darin at High Flow isn't porting anymore, or at least, not at the moment. ...I had another name from the boards, and he's not currently porting either. ....not to take away from professional talent, but you can do a good deal by yourself and still see pretty decent gains. I think there's a few threads on here about opening up the vortec base. I wouldn't just hog it out. smooth the injector boss, reshape the ceiling etc etc. You can do this without getting paper thin ports. ...then just gasket match both sides of the port. I think you'll see some decent improvement. I mean if your goal is all out blistering power, then you probably wouldn't be running TPI anyhow, right? lol.

I gasket matched my base with a dremel tool and carbide bits (which you can't buy at lowes/HD, btw) Not the best, but it sure worked. Takes a little longer, but that was a good thing for me.

I think the write up on the DIY porting was by Jim85IROC, if I remember correctly.

If you have an air compressor and a real grinder it is even easier. The right tools will make a huge difference. I'm very tempted to pull my good running car apart and port the base, it's the last thing I need to do. Abubaca -how were your results with moderate porting?

I agree the right tools help. ...however for a first timer (like myself) having to take more time with a tool that isn't as fast isn't a bad thing. Also, for smaller more precise work like gasket/port matching, the time penalty isn't nearly as bad as say fully porting for mass volume. If you HAVE the tools, and a little experience, then yes....air or electric grinders with proper carbide burrs are def the way to go. .....with regard to my results, are you talking about the porting itself, or how it affected performance? You can click on the FB link in my sig, and check the gallery to see pics. As for performance, the engine is still on the engine stand!!!!:D ....and even when it's done, it's a new 383 with new heads, cam, all that....so I'll have nothing to compare it to.
