$50 for a port-job from me (I'm not a n00b BTW) or a few hundred dollars for an air compressor + tools. I'd say short-term that's not a good comparison, but long-term buying a compressor + tools is a LIFE-SAVER. Then again you also will end up spending money on air tools and such. Still worth it...

You can get a fantastic upright air compressor from Home Depot/Lowes for $300 or around that price.

A *good* die grinder is worth the investment if you are going to be doing more than 1 job with it, but not cheap. My carbide cross-cut bits costed $15 each, and then you have to get some sand-paper rolls (look just like tootsie rolls), and some misc. other stuff.

Or she'd say your not doing either! And then we have to convince them and get the silent treatment for a few days. Until you line up against a talon tsi and smoke him. Then she smiles. And then the smile goes away and she says your sad for picking on ricers and she's not impressed

Hey now, I resent that comment. DSMs are not to be taken lightly. :thumbs up

I never said it was realistic, just a suggestion to get her on board and get a compressor. LOL

I know. Thats why we're happy when we win. But they can't see past the fart cannon that so many of them have. If it's got a cannon on it, my girlfriend just lumps it in with the ricers, even if it's decently fast

If you use bit 115 for a dremal they work great. I dont have an air compressor so a diegrinder is out and the dremal and drill is in. Use the torque of drill to get the hard stuff out and the rpm of the dremal to get it smooth. So far mine is coming out nice I'll try and post a pic when I'm done.

As for what hp is really worth. I figure if I can spend time gutting my car and making it light I can sure spend time to make a little more power. I spent along time porting my intake and getting it right so I'm not afraid off spending a little TLC on the exhaust mani.

I ported mine with a Dremel; maybe too much! It took me, well, a long, long time.

Not to get too far off topic (I think it's very relavent personally) but which would be a better hp payoff, portnig stock exh mani, or welding a flange to a TBI header?

Now that's definately something I've got back-to-back experience with.

A well-ported stock manifold will end up being a bottleneck at some point, whereas the TBI header idea will support you into MUCH higher HP levels.

Of course there's more to the TBI than just welding on a flange. The angle has to be right if you want to keep hacking your firewall or resting the turbo on the k-member. You also will need custom oil/coolant lines for you turbo. On top of that your stock swingvalve will no longer work...nor will the stock downpipe.

Things to consider if you decide to go that way...

I could care less about the coolant aspect, and oil lines are simple, I don't like SV set-up anyway, so external wastegate is ok (except for $$$$) it's the overall fitment for me, since it will be an L-Body (Charger) I don't think it will be too easy!

Well you *should* care... :thumbs up

External would be a breeze...there are plenty of spots to weld on a small piece of pipe...and then attach a wastegate to it. I've long considered doing this to my car.

WHERE you hack the old flange matters, as well as the ANGLE which you weld the new flange on. I got my setup from Forward Motion so the setup is certain to fit in even an L-body...which it does! You just gotta get the angle just right.

slow down there Rockafeller! :thumbs up I can't be all buying stuff ready made, I'm talking about having someone local to me hack off a flange from a $10 j/y turbo manifold, and put it on a $10 j/y TBI manifold Sounds like a lot of $10 manifold could be killed in the process though! LOL

[shelbyluvinfool]

what's with divider in the TBI manifold?!?! Ipulled one today and was looking at it a lot. I'm still thinking about this, std T3 turbo would be nice

Killed no...but completely misfit yes.

I would actually test-fit it all. I'd cut the old flange off...then tack on the new flange...then hang the turbo off it and plop the head in place. Well it doesn't fit...the turbo needs to angle down/up some...easy then knock off the flange with a hammer and grind the angle on the manifold some. Then repeat the tacking and such.

I'd say it'll be hard work yes, but not too bad for someone to do it themselves.

Having someone else do it will make it a one-shot deal. If it's off then you're crap outta luck.

It's fun trying to make it all work though! :thumbs up

[shelbyluvinfool]

nah, I know a couple of peeps who could help out with tacking, then take it somewhere for the final welds...what's up with the dividers inside the TBI though?
