I'm sure theirs slight indifference's but when comparing the parts that go with this system you have shorter legs on the oil pickup with the ITR and GSR's due to the main girdle so the LS's/B20's have longer legs which are needed if you forego the use of the girdle...

 

So in other words, use the b20 oil pump?

 

Correct. Its the water pump that is different between the VTEC & Non-VTEC due to the number of teeth. (22T vs. 19T). If you're changing to a VTEC head at any time, use the 22T pump and timing belt. If staying LS/B20 the standard water pump is fine.

You said you wanted simple. Keeping with the same parts as of now is as simple as it gets.

 

Alright so im just gonna use a b20 oil and water pump and ill be fine? Or just go with a brand new LS water pump and change the oil pump to a b20?

 

If the car plans to stay LS, and not LS VTEC, you can use a standard LS water pump. If there is nothing wrong with the LS oil pump you have, you can stick with that as well.

There's no advantage to going to LS , B20 or other oil pump. As stated, they are the same part number for B-series engines. Get new ones if you'd like for better insurance. If things are ok, and its low mileage leave them alone.

You're starting to make things a little more complicated than necessary, .. Just relax. ONLY the water pump part numbers are different, not the oil pumps.

 

Thx Shodan lol yeah i have around 220K miles so im gonna go ahead an just replace them

 

Actually it really doesn't matter where the IAT sensor is as long as its tuned with it in the same location. (unless its a stock car)

For example if it was in the manifold, reading 110 degrees on a normal day when its tuned, thats where the correction tables would be zeroed out. So there are no fuel or timing corrections at 110 degrees F. The air actually making it into the manifold might really be 90 degrees but the computer doesnt care. Its going to be tuned to an AFR target.

If it was in the charge pipe it might read 90 degrees normally, but if its tuned there then thats the temp the corrections are zeroed at. So it has no affect in the big scale. Its just better, more accurate data if you are trying to fine tune things.

 

If or when I make this alteration I will retune as needed for this change regarding my IAT values or when the onset of timing being pulled begins and how quickly it ramps up.....what I'm hoping for is a correlation of power retention from slower increasing IAT's being outside the manifold where heatsoak wont be so much a factor and so if needed and I notice any slight chances of det or power loss from having the values where their at I can also increase or alter when the IAT and when ECT timing comes into play but all together I'm curious to see how this pans out with hotter weather down here in FL....

 

Like I said, it doesn't matter how quickly the temp changes. whatever values are in the tables are what the computer is going to follow. Your just shifting around the data points essentially. If it takes X amount of fuel to reach the target AFR when the sensor is in the manifold reading 110, its going to take the same X amount of fuel as if its in the charge pipe. Your just getting a closer value to the airs true temperature.

The only time I can see there being a noticeable difference is when you are sitting in traffic or staging lanes at the track when the sensor gets heat soaked and climbs to 150+. It goes down relatively quickly once you get air moving but that 30 seconds or so its going to be adding more fuel and pulling timing depending on the compensation tables.

Your IAT's shouldn't be increasing under load, that would be a sign of an ineffective intercooler.

 

I understand what you're saying and your right...And...I might not have the most efficient IC but it's a lowboost setup rightnow for that matter however I can tell you that stop and go traffic with boost in August or September in central FL is a power killer and im sure if I were a few states more north it might make that much more of a difference but the rate at which the heatsoak occurs is my reason for this as you stated so if anything...if I notice positive results from this change I'll definitely outline the differences in the tuning forum :-)
