3.0L Header Dyno #s ?
#42
WHY...why...why. Damn this timing is sh!tty. Oh well.
Looks like next month could be a NEW era for VQ30DE-K owners.

I believe the 3.5 is wider than the 3.0? Visually it looks that way, of course I could be wrong. I'm worried that the 2nd manifold or the part that replaces the y-pipe won't bolt up right or have problems clearing mechanical components.

Larrio..given what I've read on the other mother of all threads (the TS ECU thread) I would think that the ECU could/should be optimized for the headers and not vice-versa & that would imply the headers should go on first, no?
Alex, can u chime in here??

EDIT: oh and btw, I just sent the cattman y-pipe back to SWA already.

TS will most likely custom tune him a map for his headers, which will be AVAILABLE to all of us, AFTER a STOCK program is made. That's great news for all of us planning on headers.
Headers will just lean out the AFR, so they'll have to add some more fuel. We'd all be best off getting the best matching program to our current/future mods and then using an Apexi S-AFC or similar to fine tune on a dyno.

You guys need to worry about HELPING FIND us more test-cars and NOT about how the details will work out.
Danny's got all that covered, we just need to make sure we have 100% rock solid guinea-pigs ready for Dannys' earliest convienence.

Yeah, add your name to the list:

I'll buy these next month if no one does the test by then... my car is far from stock, I have a plasma cutter and a MIG,TIG for my convinience. I just hope all the bolts come apart EZ, almost 100K miles on my 01. I might be able to send a spare 01 Cali GXE 5spd ECU to TS for a test mule.

I wonder if [edit]STEVE [/edit] can get a picture of the HotShot headers next to Cattmans NZ headers.
That might help visualize.

here is a comparison picture that I put together:
looks alot different to me, but it could be from the different angles. The HS is truly a longer tube header design. I suspect potential problems getting the 2nd parts to bolt up to the 1st manifolds

Those look VERY similar to me.
I don't see the problem. Can you circle it?

If you're talking about the loop on the rear bank, I doubt that's a concern, but I'll look tonight and see.
If it is, I don't see why that couldn't be fixed by going with a Cattman y-pipe style rear, ie lose the loop/equal length and just merge as short as possible. Definitely wouldn't be too much work for the welding inclined.
If you had to pay for welding it, you might as well go with the Cattman version.

i just don't want that 2nd equal length loop to hit anything. Hard to tell what could happen at this point. otherwise the manifolds look the same shape
also, why does the cattman header look so much shorter in length?

ice, how hard is this install? Do you have any ideas what type of tools are needed? I was thinking that if I have the right tools and no need to remove the radiator, I will do the test fitment by myself so that I can return it back to stock later
#69
From what SR20DEN has said, not easy. REAR bank is a bish.
You aren't going to install/uninstall/reinstall TRUST ME.

FYI, the Nissan shop manual says in the range of 2.1 labor hours for the front bank and like 2.6 for the rear bank....four hours for a good, experienced tech with the right tools...this surely 'aint' trivial by any means...

Pretty EZ job if U ask me, loosen the cross member, drop the OE or aftermarket Ypipe, remove the rear motor mount WITH the cross member attached. Then Remove the motor mount bracket that bolts up to the rear of the motor. For the front manifold I pull the radiator out- pretty ez job ( and I'ma be due for a coolant flush soon anyways ) just remove the hoses from the motor locations, unplug the fans from their connectors, remove the overflow hose that goes off the radiator neck nipple and then the 2 10mm bolts that hold down the brackets that hold the radiator down. I will write up my own procedure on how to install headers when mine arrive. I've done cats on a VQ30DE-K on the front so I know how the manifold comes off the front. I inspected CLOSELY- rear manifold and its fairly EZ job. I wanna say U can have it done in like 2-3 hours tops. **** pulling the motor out takes a whoppn hour not even, might as well do that if it takes ya dat long
FYI- I'm a mechanic, and I do things like these on daily basis- Maxima tranny takes 15 min to remove on my ride. Don't belive me, look where my sig line pic is taken

Is it on Cattmans?

What some of us SR20 guys do is have a muffler shop extend the EGR pipe way down, and then have it welded to the exhaust somewhere- on turbo cars its in the downpipe- for people who wanna retain EGR valves. Most Sentras are not streetable once they are over 250WHP (ez to do) so most of us don't worry bout it.
#80
VQ30DE-K and VQ35DE have no EGR, so there should be no welding required. As for the downstream 02 sensors, I can use a simple resistor that DSM, WRX guys use to fool the ECU into thinking the cats work fine. In IL they only do the scanner part of the Emission test on all 96 and up cars. As long as all readiness tests have completed, and there are no DTCs stored the car will fly through the test.
