Hi Guys,

I recently blew up my LS Vtec High compression engine (11.5:1) due to various reasons that i won't get into.

I am rebuilding my engine. B18A1 block, B16A1 head. JE low compression pistons, forged eagle rods, type R cams, aem adjustable cam gears, Hondata s200, full msd, arp headstuds, sir trans, yadda yadda.

For a turbo I'm running a T3 super 60 off of a 2.5L mustang. Tial 38mm wastegate, 2.5inch downpipe, jrc intercooler, greddy type-s blow off valve, etc. Looking for a tune of around 14-15psi (stock sleeves). Due to a custom install and fabrication in my car I was able to keep the full sized radiator to help with cooling.

Car is a '90 integra. The question I have is:
Do I need to upgrade my water pump to say, a Type R, GSR, B16DelSol. Basically to an engine's that had Vtec?

ummmm all water pumps are the same the only difference is the number of teeth where the timing belt goes.

 

Oh... I heard some flow more than others?

both the GSR and Type R are the same part number from Acura

They all flow the same..... think about it.... your timing belt is what drives the water pump. How is one going to flow more than the other? they are all shaped the same on the inside
