Just posting some recent mods

Just got done with the boost gage- it fit pretty well without too much modification. I can post install pics if needed. Also, thats just plexi i cut to fit over the silencer holes and i also did the same to the ones under the bottom

what size pulley is that

Its a 2.5"

how much did the boost gauge cost and how would you go about hooking that up so it actually works?

how much power did the 2.5 add and what other mods do you need to run so it performs well

The 2.5 pulley made quite a difference in the off the line power- which really didnt need to be helped. the tires melt if you nail it off the line followed by a way to soon shift into second gear. Overall though, i did the 104's and a larger idler pulley to make up the slack in the belt. Other than sealing and gutting the intake, thats pretty much it. I would recommend programming, or flashing in my case, the computer and upgrading the fuel pump with a 255 lph unit and a adjustable fuel pressure regulator. The fuel is a critical issue on the OBD 1's because the factory stuff just barely got the job in stock trim. I would not reccomend the 2.5 if you dont upgrade the fuel system or you will be putting a motor in it like i;m doing now.

How would one go about flashing and what specific type of fuel pump and regulator?

As far as the computer tuning, go to www.gmtuners.com for the pcm programming. The company's name is Sinister Performance Llc. I would recommend a Walbro 255lph pump. you can get one for $77.95 at maperformance.com You can get an adjustale fuel pressure regulator MSD 2220 for $69.40 at atlanticspeed.com. Or of course you could also just hit up google like I just did ha...

Thanks, I went to intense and wasn't sure if the Walbro would work with a 95. They had something called a "Venturi Specific" walbro. I'm going to look into which I need. I had no idea where to get the pcm done. Thanks again!

it works i installed it in my 95

.. just to clarify, is this the pump we are talking about?

could the rewire kit be adapted for a 95?
