I am planning on doing the TPI to HSR swap this spring and looking to get all the parts before I start the swap so I dont have to stop on run to get more parts. Here is a list of parts that I think is required to do the swap. I am really looking for all those little connector parts needed to connect all hoses and lines back up. This will be going on my 89 Firebird 350 TPI with Ram Air 2 hood so it will clear the hood. Holley Stealth Ram intake Non Vortec Fuel Rails and adjustable fuel regulator through Professional Product Part #10608 Felpro Gasket 1205 Got this list from Doug Flynn on another thread on here - Use a std. small block Chevy waterneck (Mr. Gasket PN 2661) -Two 1/4" x 1/8"NPT straight barb fittings (rear of intake, MAP sensor and other items, I run only one line to MAP) -One 3/8" x 3/8" NPT straight barb fitting (rear of intake other vacuum items) -One 3/8" x 3/8" NPT 90 deg. barb (goes under plenum, used for brake booster) - 2 feet 1/4" vacuum hose - 2 feet 3/8" vacuum hose - (1) 5/16" compression fitting to -6 male AN - (1) 3/8" compression fitting to -6 male AN - (2) 3-1/2 foot -6 line with female hose ends. Goes from inlet and outlet to fuel stock fuel lines which are cut from underneath car, the two compression fittings are installed on the stock fuel line. - (3) 1/4" vacuum plugs for EGR solenoid and throttle body - (1) large clamp http://www.holley.com/HiOctn/ProdLin...A/9894DBH.html The 9894DBH & 9894DBJ are the ones needed for the stock hard lines the other two are used if you want to come off the stock rubber lines in front of the manifold. I know I will need a new chip burnt, thinking of getting my own chip burning and tunning equipment from moates.com to do it myself, but if anyone has any suggestion on where I can get one done for my specs I would appreciate the help. I will be using the stock TB, I know a bigger one will help but for now the stock will work. I have a custom CAI on the car as well. Not really sure what else is needed. If I have missed anything please chime in and let me know.

that is all You need

Gnarly KIT David!!

you could buy 14 and 16mm to 6an fittings to run braided line from your hardlines in the stock location without cutting them underneath the car. Take out your stock rubber lines, and replace them with braided line. you will only need 6ft of line since they sell line in 6 foot lengths, cut it in half or so and get the appropriate hose end fittings. Alot easier to do it that way but its cleaner to cut the lines underneath the car

I was only commenting about how I like the NightRider Firebird look on Gambit69's ride. I should have said "Gnarly K.I.T. Michael", but the actors real name is David.

Moates makes great stuff. I used them when I converted to the '730 and then the '749 ECM on my '87 T/A. However, when I added the HSR and the STS RMT kit I switched to a Megasquirt ECM. Much easier to tune.

I have seen others use the stock TB, but I have heard it need to be modified to work with the HSR. I added a LT1 58MM TB to my HSR, but I had to change throttle cable to a lokar one.

I cut the hard lines on mine and it makes a much cleaner install I think, and that is important to me because I show my car.

Best of luck.

I used my stock throttle body and it worked fine. I even used my stock TPI cable bracket. Just read the instructions and follow them to a T. I made custom lines from the FP to the rails, but I didn't have stock fuel lines for fuel injection as my car is an 84 that came with a carb. I don't have any insight, but you can't see my fuel lines and it works fine. if you would like to know what I did with the lines I would be glad to share. I converted to TPI before the HSR.

I just want to be sure I am looking at the right part. If anyone can help I would greatly appreciate it.

There are a few parts that I am not sure on what to get so if anyone could help me with those as well I would appreciate it. These are the parts that I have selected for the conversion. If anyone can look them over to be sure I am getting what I need. If not could you suggest a different part instead. Thanks for everyones help.

The compression fittings and (2) 3-1/2 foot -6 line with female ends are only necessary if you're cutting your stock fuel lines under the car and need to adapt hose to that cut hard line. If you buy the braided line and 14/16 mm fittings you won't have to cut the hard line, just unscrew your current rubber fuel hose and screw in the appropriate fittings attached to your braided line.

My question is, how do the Professional Products fuel rails bolt up? Pretty good? I didn't know there was any alternative to using Holley's kit.

any updates?

I ended up purchasing the Professional Products fuel rails and they fit just fine. I posted a review of them and a good price at Flatlander Racing in the Aftermarket Product Review forum. I still need to order the fittings and gaskets and do the HSR swap on my car, I will use the part numbers in this thread and update when I do that.

I dont even know if anyone will read this but i installed a HSR on my 88 GTA with out any other mods to the computer. I had to modify the bottom of the throttle body a little cause i didnt get the right water neck. i put 24# injectors in it used the stock throttle body and I used braided #6 and adapters that you can get from just about anywhere you get the braided line from. and it looks good too. My car ran real good too. with out any kind of custom chip burt. In fact my motor had a 500 and something lift cam a set of world product heads, headers and a decent exhaust. the car went like 13.4s in the quarter and got like 20 mpg. But a roller went bad in a lifter and ruined it all. But any who thats what i have done.

I used my stock TB and it worked great with a little clearancing for the t-stat neck. Running 8.40's 1/8 mi na. Stock TB isn't a restriction in my opinion.

And yes you will need reprogramming and the Moates hardware works great. Be patient and apply all you know about carbs and timing. It's just controlled differently and there's a lot of different ways to accomplish the same thing.

The HSR is a great intake system in my opinion and well worth the investment in $$ and time to get it working properly. My car is a daily driver and running mid 7's 1/8 (with a mild shot of n2o) and 17/22 MPG with a 3.70 gear. Don't be swayed by the "you'll lose torque over a TPI" claims. Any loss of low end (I didn't notice any) is far out weighed by the mid and upper power.

here's what i used and the cost

I'm in the process of installing my fuel lines. Where did you cut your lines underneath?
