Look at the huge collector (3 inch)

EGR bung I had hotshot weld in. I dont like how far it protrudes. Will have fun with the dremel on that one. You can see they actually ground it down some already.

Um, in the first post...?

3" collector on a 4 cyl?

wtf...

Yup, this header is designed for SR20's with big aftermarket cams with lots of overlap, or the SR20VE (which, has big cams up top).

I already have a Gen5 Hotshot header, this is the Gen6. It will be for my VE when I get it. Here is a dyno. Its an SR20 with a Gen5, then a Gen6 with a 3 inch exhaust. Can't argue with results:

that plot is too smooth. where's the vtec?

- mpg9999 - 10-21-2004

1. Nissans dont have Vtec, they have NEO VVL.

2. They dyno is not of an SR20VE, its the SR20DE with JWT cams.

You would be better off with a long tube 4-1 header and 2.5" collector, IMHO. Ground clearance be dammed.

Not according to Hotshots R&D. My current header has a 2.5 inch collector (and so does the one they dynoed the Gen6 against). It is also a Tri Y.

- .RJ - 10-21-2004

Tri Y != long tube 4-1.

I understand the reasons for making it the way they do, but I think its dumb.

And that is why you don't design headers for a living.

- .RJ - 10-21-2004

I'd like to see SMSP make a header for it Wink

how is a tri-y not a 4-2-1? and if he isn't losing power, it's dumb to think it's dumb Big Grin

- 83Rabbit - 10-21-2004

Isnt it beneficial to have every runner the same legnth....?

Cyl 1 and 4 look to be a MUCH different legnth. :?:

83Rabbit Wrote:Cyl 1 and 4 look to be a MUCH different legnth. :?:

the kink in runners 1 and 4, plus the length they have to extend outward to clear 2 and 3 makes those runners just about equal by the time they merge, i think.

- mpg9999 - 10-21-2004

There is a difference of a little over an inch. My guess is it has to be that way for clearance/design issues.

Im talking 1 and 4 different legnths from 2 and 3 :wink:

You're buying parts for an engine you don't own yet...

Sounds like some sort of weird strain of boost rot.

Yup, also bought a MAF for it, and an ECU. Collecting all the needed parts now. The engine will be the last item because they generally have a 2-4 week start up warrently. That means right after I buy it I need to install it. Plus, its to cold right now. Just waiting for spring to roll around...
