Water pump installation. It would be to your advantage if you went out and purchased an OEM ITR/GSR (P72) water pump. But, if you use this water pump, you must also use the ITR/GSR (P72) timing belt. If you use the LS water pump, use the LS timing belt. The P72 water pump has 22 teeth as opposed to the 19 teeth on the LS pump. This means the GSR pump spins slower at higher RPM's, and vise versa. You may think this is bad, but it is good, because at those higher RPM's with an LS water pump, you will theoretically be spinning the pump so fast, that it doesn't even push water; it just creates bubbles (cavitation). Get it? Ok, so take your water pump now and spread a bead of RTV in the gasket groove, and then slip in the gasket. Bolt up the water pump and torque down to specs. Tighten them down in a criss-cross pattern as you would lug nuts. Do not overtighten as you can warp the pump or crack it, possibly even strip the bolts. Bad.

I had forgotten that the pulley on the GSR pump is larger, I just remembered that the impeller slightly is smaller with one fewer blade.

If you want to use the GSR pump, by all means go for it.

- Thu Jan 21, 2010 7:45 pm #170082 i actually found it on honda swap....it's a pretty good article about building a "reliable" LS/VTEC. i found it pretty interesting how the gsr and the Ls are so different. the LS just isn't built to rev :D

- Fri Jan 22, 2010 2:37 am #170200 run a catch can....with boost you build up a lot of crankcase pressure and you need to vacate it. if you don't you can blow out the front and rear main seals, the dipstick tube, burn oil and have increased blow by. if you leave a little breather filter on the port of the VC, it will become saturated and blow oil all over the engine bay after a little bit.

what i did is simple... hose from the black box on the block, hose from the stock VC port to a vented catch can located at your convenience in the bay.

- Fri Jan 22, 2010 9:10 am #170291 well i didn't want to pay that much for one so i made my own :thumb: but i wouldn't drain anything that the catch can catches back in to the oiling system as it contains spent fuel/ oil vapors/ blow by and condensation, i personally wouldn't put that back in to the block.

i did a low budget catch and works great: i have 2 vent tubes that go out under car along with the two i said above:

- Sat Jan 23, 2010 4:40 am #170504 I don't put a catch can on anything making under 450-500. If you do run one, take the black box off the back of the block, weld a fitting to it, then put it back on, then run a line from the bottom of your catch can to that fitting and now you have a drain system. no worries about this stuff>spent fuel/ oil vapors/ blow by and condensation,

so question...what do you do with the stock plug? now that you have welded one on?

cause i get it...usually it's 2 ports from the VC to a catch can but what do you do with the black box connection?

- Fri Jan 29, 2010 4:33 am #171851 bump for that ^ Q, and i got another......




since i'm gonna be runnin a kind of big intercooler, I figure i'm gonna have some boost loss with the WGA getting its vacuum source from the end of the compressor outlet. is too much psi loss gonna cause a problem for tuning??


and if I'm understanding what i'm reading, I can run the WGA hose to a vacuum block by the IM safely with a good BOV in use to fight the comp surge, and get more accurate psi that should match what the boost guage reads....


got inputs?? :thumb:

and got another question....



Whats the deal with gap around the "plunger" of the wastegate. seems like it would let quite a bit of exhaust past?? i thought mine may be missing some sort of seal there, but i guess not..


best pic i could find. you can see light around the plunger (the gap) whats up with this??
