![]() I was thinking about getting the kit from Holley and was wondering what else would I need to install it on a bone stock 5.0L? Do I need bigger injectors, bigger mass air and throttle body, new fuel pump, headers just to name a few? What else?
Or, should I just go to a Vortech S blower and keep everything else stock? Looks like the price would be about the same. All I want is a decent 300+ HP motor... Any other choices? |

![]() well if you got the Systemax II package, you'd need injectors, MAF and TB/EGR to make the power. Plus you'd want to get an adjustable FPR and gauge, etc.
As far as the blower option goes, I dunno squat about superchargers. Sorry

![]() If your only going to run 6lbs of boost and want about 300 hp, you could just get away with just the injectors and a fuel pump going supercharged.
With the Holley kit, I would just add a fuel pump. I've seen stock 19lb injectors run 11.90's in the 1/4. If all your after is 300 hp, I would stay NA, that way you don't have to worry about belts. The larger injectors, mass air, TB, headers, and an h-pipe would really wake both combinations up though. You didn't say whether you were after 300 rwhp or fwhp. With either combo you want have a problem reaching the 300 fwhp mark. The Holley kit would probably make more hp than just 6lbs of boost though.

![]() The holly kit is really a good one. Also a very good place to start on your quest to 300hp. Remeber, that an engine is nothing more than a sofisticated air pump and the more you can stuff in and get out the more power you can make. The blower is a good choice, however with any blown application you will have to maintain a tight tune on your car at all times. and all it takes is one time under boost in a lean air/fuel condition, you might melt your slugs or worse detonate, in which case bye-bye motor. If you go with the blower get a kit that come with an intercooler their more work but worth it for performance and reliability. but I 'd still go with the systemax that will give a solid foundation to work with for later upgrades.

![]() I think I like the idea of staying N/A.... Like it was said, the Holley kit is a good place to start but it is only a start. I guess I still need a few more $$$$ for the other miscellaneous parts. I haven't even thought about labor costs yet... Do I trust myself to do this install or have someone else do it???!?!?!?

![]() When it comes to the installation of heads, cam and intake. If you've never done it before, and you want to do it yourself, I'd STRONGLY suggest that you have someone there with you to show you how to do it. There are many little things that can easily be done incorrectly with lack of experience. I'm not trying to tell you to pay someone to do it, but if you don't know anyone with this knowledge that can help you out, then you may be in for some labor charges. It's really up to you. What kind of a tool surplus do you have?

![]() Yea, good call DR, if you have never performed such an undertaking, it would be a real good idea to have someone there to help with the more difficult parts of the installation such as cam timing and stuff.

![]() The Holley kit comes with a "you need list"
From what I can remember it goes something like this. 24 or 30 pph injectors, 65mm tbody,190fuel pump,75mm air meter or bigger, 1.6or(I have 1.7)rr, gaskets. Thats all I can think of. I put my kit on at 100k miles after a compression test said good and got 303hp/307tq to the rear wheels here in Fla in warm weather. Be careful with their heads though. I recently found out that they need valve guides with less than 1k miles and the warranty was up 2 months before I found out it was the heads. Holley said sooo sad- tooo bad. My next heads will be street heat. Good luck
