so im lookin to throw the whole fast 102mm top end setup on my ls1 (intake, tb, fuel rails) and ive heard there are a few fitment issues with the intake and tb coming in contact with the water pump pulley. if anyone has ran across this issue and fixed it or has any feedback on any of those parts id appreciate it

also if anyone thinks the meziere water pump is worth the money. they advertise the life expectancy is 3000+ hours, im not payin what theyre askin for it to last such a short time

That is over a five year life expectancy. The pumps are a excellent option, but not exactly sure how it would fix your issue.

i still have the stock water pump on it now but i just dont want any clearance issues out of the fast intake and tb. thats really what im lookin to solve. ive got a friend of mine that has a 2000 ss with a meziere pump on his and he loves it. said he got about a 10-12 horse gain at the wheels with it

The fast 102 fits just fine, alittle tight fit but there easy to install. For the TB you just have to grind alittle off of the TB with a dremel for it to clear the water pump. I did three fast 102 installs on the fbody and had to take alittle off of the TB on all three. It's not hard.

I grounded alittle off of both ( W/P and TB ) also if you have the coolant piping that goes under the intake, pay attention to the clearance between the pipe and the bottom of intake. I had grind alittle of the bottom of the intake to clear.

I have zero issues with anything hitting the TB on my 102 setup, I didnt have to touch the intake or TB. I did have to tweak the coolant cross over pipe by bending it down a little to clear the bottom of the intake where it hangs off the front of the valley. You "may" need to massage the water pump at the top around the 1 o'clock where a bolt boss is. I had sufficient clearance, but cleaned the casting flaws off anyhow. Also, where the pump is bolted together (bolts heads facing the timing cover) they may contact the cover. A quick hit with a grinder solves that issue. Personally, I think its very simple to get fitted. I dont know what all the fuss is about on the posts I have read in the past.

If you have the newer style water pump, it should clear the water pump as is or w/ very minor grinding of the pump. I also highly suggest the LS3 style coolant cross over. It fits better under the intake than the LS6 one. IMHO the intake appears to be designed around the LS3 tube as the LS6 fit like ***.

aight sounds good, where have you found the ls3 coolant crossovers at???
