Doug Fab SR20VE trials!!!
Hey all,

I see a lot of talk about headers that work and don't work.
N/A game is something im trying to work with here at the shop.

Ive decided on my shop B14 to run the car N/A in order to test some items I am looking to prototype.

First things first need to get car running to where I have a base setup/tune and then perform mods!

Car as it sits right now has a bone stock SR20VE, stock intake + DE throttle body, Nismotronic, ID1000 injs, Aero 340 fuel pump, 3" VRS header back, muffler still TBD

I will be fabbing a cold air intake for the car, 3" from TB to fender well - filter will sit under fender well where stock silencer box use to be.

Here is where my trials begin.

For a budget build ive decided to take a Honda B series Tri Y from PLM and modify to fit to VE.

After talking to a few folks they seem to think its worth the investment for a street car.

Shit ! For the $250 I spent for a brand New PLM Tri Y ,id say its worth a try.
I looked into fabbing one from scratch and I would spend double in materials just to duplicate what they have already made. The quality of the header is very good. Better then I expected. Mild steel flanges which are best to prevent warping and full 304ss tubing, slip collectors don't look half bad either.

Looking at the pics you can see I need to cut off head flange and accommodate a SR20VE head flange. Duh!
You can also see that the primaries actually need to be reversed from how a B series needs them to how I need them on the VE.

In the next couple weeks I will be fooling with this header to see if it truly is worth the investment.
The cost of $250 + my time modify the header.

After I get car running I will dyno it for a baseline,
then car will receive an intake manifold. I have 2 diff prototypes I want to try out for this. I will keep you all posted.

I will install N1 cams and see how those perform.

Some other mods may be in the works as I go along.

I hoping so. honestly im doing this mainly for me. I don't really plan on doing these headers in a mass production.
I do want everyone to see what can be done on a budget though. this modification may either go or blow. time will tell.

the other components I am fabbing will deff be available. intake manifolds, cold air intakes and whatever else I decide I have time to fab.

things at shop are just so busy I don't have time to do a lot of multiples, most stuff is one off. I am only one person. haha

The biggest thing that I'd do is lose the slipons - they ARE Chinese afterall. Permanent welds (if u can reach inside) will be much better... it won't take long before you can hear/feel air escaping from the slip-ons. Once you get your design fitting... a quick call to stainlessheaders.com and you can get production going. Subscribed.

I can only imagine that they may not be the greatest. I have yet to assemble the slip fits yet. one was a little bent in prob from shipping. but no biggie.

I would deff weld the seam but I do like having header 2 piece. helps gget the header in and out of car easily. getting that 4-1 out of the car was not an easy task.

If that header its the regular tube one you need to open the choke on the last merge collector to 2.25in!!!

it is the standard tube header. I will be cutting the 2 bolt flange off right after that last 2-1 collector. once I do I will measure diameter.

If its smaller then 2.25 I will cut I back a bit and open it up.
