well, it was time i did this entry... courtesy of enjukuracing.com i got myself a isis intake manifold, greddy knockoff yeah... but the reason i went with this one was to mock up my engine and i ended up liking it... the quality is good, welds are good and the polished finish is baller... the inside isn't porous and you can see the quality compared to most of the ebay brands...
ISIS Intake Manifold - Nissan SR20DET S13
The day it arrived from enjuku... comes with EVERYTHING you need for the install...
the runners and inside
Some pictures
the only bad thing MINE had, but none of the rest have had this, was this little thing here, a piece of casting that i wasn't really comfortable with, it was at the end of the hole that goes to the fitting of the brake booster vacuum hose... i just knocked it off with a few hammer hits and a crowbar... it didn't come of easy but i didn't want to take any risk... besides that the inside was really clean in my opinion.
the install was easy... there's a bunch of write ups installing the greddy manifold, it's exactly the same. I did not encounter any of the symptoms and problems that people have with they're ebay manifolds... so that is a plus for isis... i found it easier to remove first the fuel rail, and after that take of the brackets that hold up the intake manifold from under it, i ended up removing the top runners first and then the lower plenum, it made it easier for me...
the only modification i needed to do was:
1-modify fuel rail: simply done with a dremel
a) cut off some extra brackets that won't let the fuel rail fit
b) bore on of the bolt holes bigger so a bolt will line up correctly
2-modify throttle cable and bracket (i used the stock SR bracket and modified my SOHC cable to work... it feels nice and is holding up strong)
3- the throttle body won't sit flush with the stock bolts you have two options:
a) use washers like i did
b) use shorter bolts
i broke the gaskets for the AICV and THROTTLE, they were all dried up and broken to start with... so i ordered these from FRSPORT.com and i got a free tshirt with my order =) great service and EXTREMELY fast shipping... plus part numbers for anybody that needs them...
A mock up to see how it's gonna look at the end...
note: i haven't been able to try it because of the cold pipe i need to make, which i ordered yesterday so i hope to try this out... i have stock everything so any improvement will be because of this and not any other parts i have installed...
