From PRC 5.3 & Unported FAST 92 >> to >> PRC 215 & Ported FAST 102 ...... worth ?
Hey,
My 02 SS M6 dynoed 434 rwhp / 411 rwtq last time with the current setup
Engine 02 LS1
- PRC 5.3 Stg 2.5 milled to 59cc | SCR is ~ 11.2:1
- EPS 222/226 115 lsa
- Mahle Forged Piston 3.898"
- Eagle Forged Rods 6.125"
- Stock Crankshaft
Other Bolt-Ons
- Uported FAST 92/92
- ZO6 MAF
- TSP 1 7/8" headers | Custom ORY | SLP LM1
- SLP U/D Pulley
Here is the dyno graph making 428 rwhp / 410 rwtq with cutout closed
I'm really happy with the setup and the car feels great with the feeling of power everywhere , Now I would like to upgrade the heads to PRC 215 milled to 59cc & Mamofied 102mm FAST intake along with the 102mm TB since my friend give me a good deal for the PRC 5.3 and 92mm intake
Actually I'm not looking for dyno numbers, I need really gains in the street
So do you think I will notice the gains in the street regardless of dyno numbers ? If yes , does is worth spending the money on that ?

The no brainer answer to your question is: YES, IT WORTH IT
I will be very interested to know what kind of power you will be making with a Mamofied 102 FAST and PRC 215 with all the required supporting mods (injectors, 1 7/8" LT's, UD pulley, EWP, ....etc) on a stock LS1 short block.
Those heads are as good as TFS 215 and AFR 215 but they are not as popular.
With a custom cam (obviously bigger than the cam you have now), I guess that you will be in ballpark of 490rwhp+
Good luck with your build.
