Question about Direct Port Nitrous on a TPI setup....
First of all, can you actually BUY a direct port nitrous system or is this something that you have to put together by buying various parts individually??
IF this is something that you have to buy individual parts for in order to put it together, can someone give me a list of what all I will need in order to do this? What kind of modifications do you have to do to the Intake and/or runners?? Can someone tell me or point me to a place that will tell me how to hook this system up?? I'd really like to do this with my engine.

It looks cool and is more expensive and harder to change jets. I would stick with a plate unless. you plan to go really hard core in the future. on your car I really don't see a huge advantage.

Yep you can buy a kit.
The good folks at Nitrous Express come through again.
You can find info on their direct port EFI kits here.

l think the plate that comes with the NOS kit #5151 for the TPI V-8 (dependant upon jetting) is good up to 200 HP. IMO its needless holes in the intake for a direct port, unless you intend to run over 200 HP
