Ok so im finishing up my turbo set up on my LS integra and was looking into changing the oil pump. Will a new OEM replacement work well or should i buy a high flow pump? Did any of you turbo guys change your pumps?

Here's some info on my set up:
Parts on the Cylinder Head:
Crower Camshafts
Crower Valve Springs
Crower Retainers
KMS Valves ( std size)
Port & Polish

Cylinder Block:
LS Pistons
Block Guard
LS Rods
New Bearings

Not looking to make much power but just trying to beef up the motor a bit.

 

Ideally a nice p30 or p73 oil pump would be nice. or a new p75 LS. but ONLY get a honda oil pump ONLY!!!

 

i have only ever used an oe pump. making over 700 on a stock itr pump.

 

two @600hp cars on oem.
had a grenade problem that was traced back to a bad crank pulley and no dowel pins between the tranny and block. no problems since.

 

Will do thank you!!!

Thank You guys also.... how are you guys making those crazy numbers? Whats your set up?

 

built bottom end. nice turbo and manifold. msd, odds and ends AND a really good tune

 

i used a brand new OEM oil pump on my current build. right from startup i had a low oil pressure issue. about 50-55psi MAX.

so i looked for a different solution and i came up with this: http://cgi.ebay.com/ebaymotors/B16-B...Q5fAccessories

he basically take a new OEM pump and ports it out. puts in a new billet oil pump gear and shims the relief spring for more pressure.

endyn offers the same service but without changing the gear rotor.

i now get a solid 80psi of oil pressure. and it can go as high as 90-95psi before the relief valve opens and settles to 80-85psi.

most people have good luck with a untouched OEM pump.

 

i have the endyn pump on my motor very pleased with its performance

 

i was always a little scared to run the oem oil pump gears so i always use the toda gears in a oem housing
