i believe the 100 plate alone ups you around 100hp in the center of the pump, im running the stage 2 injectors form pensacola in my truck and they were a good upgrade for the money. i used to be right around 43lbs of boost but it has dropped to around 38 i may have some leaks, anyone ever cracked an intercooler?

ur probably around 300hp, put in a rack plug which is like 20 bux shipped and that'll help too. also idk wat u mean by fully tuned but u need 2 do the washer flip and grind the barrel on the aneroid arm if u havent already

the rack plug isnt to bad, i used a dremel with a high speed cutting bit, it cut the timing cover like butter, once the stock one is out use a few screw drivers to hold it in place while you get the threads started. i would also find some used 181 dvs and swapped them with your 131s. 3k or 4k govenor springs would also bring make a big differnce.

def trying to get a set of gov springs but other than that i think im gettin plenty of fuel because my hybrid cant even clear all the smoke up with 43 pounds of boost im runnin like 1200 on flat ground and 1500+ uphill i was thinkin bump the timing or a bigger turbo or even twins but i dont know what my tolerances are with head gaskets and other internals to what they can handle...

also i am trying to figure out what kind turbo to pair up with my hybrid or my old hx35 that has about 8000 miles on it what would you guys reccomend???

ht3b with a small exhaust housing would work well.

Go with the 4k springs right off the bat, the 3ks are really not worth it IMO

can stock heads and valve springs handle 4k? i dont have much experince with those ones but i heard somewhere the pistons may hit the valves??? correct me if im wrong

whats the opinion on the adjustible govenor spring kits are they worth it?

your stock head is at its limits around 45lbs of boost, i wouldnt go much over that without studs

i was told today not to go with the 4k with my stock head set up. i have the 3k and like it but the 4k fuel alot harder. i got some 75hp new injectors and really wanted to go with the extra small spring to make it 4k. but the pro's at the shop highly advised againts it until upgrading my head set up. just my 2 cents
