I bought a PLM header to install on B18C on a EJ8 body.. I am getting fitment issues.. It's hitting the transmission Kindly please check the photos below

Is this a B-Series Header ?



The bolt and hole is not alligned but it's already hitting the trasmission



Another photo hitting the transmission



What are your suggestions ? Or is this the wrong header ?

BTW we arlready tried fitting in the bolts and hole on the pictures but the front part of the header is hitting the Rad fan.. sigh

Please help

interesting header. dont ever be afraid to chop out webbign in a transmission or block. theres alot of webbign to chop out and you would be fine. the flange does look like a b series. but seems more like a headach to deal with

Thanks for replying.. No I'd rather not chop out... I guess this will go back to the shop were I bought it from

All the B series 4-1 headers I've seen the tubes go almost perfectly straight down, not off to the side.

The "Narrow-style" header requires you to trim the radiator fan shroud. And depending on weather or not you have an OEM radiator, you may need to trim the fan blade tips like I did (aftermarket dual-core). My older Kiddracing version definitely didn't require any trimming of the block or anything crazy like that. It even easily clears the Type-R transmission brace.







Here is my Clutch Slave Cylinder clearance:



You will also have to trim the lower splash sheild if you still have it in place.

What you're talking about is an ITR replica. PLM (Private Label Mfg) has their own style, which is what OP posted.

lol! The "Narrow-Style" Header is a replica of a true equal-length street/race header originally designed by AMR to accommodate Power steering and AC while maintaining great clearance. If you've never seen this style header, you've been under an OEM/JDM rock for 8 years or so.

Sounds about right.

i got this exact header, i had rad fan/shroud fitment issues but cut the plastic back just enough to clear and that was all clearance issues for me, b18c1, pre 94 teg ls trans w/cable-hyrdo conversion so my salve cylinder is vertical

I'm installing a new rad/fan and will retry to install this again... the b18c is on my ej8 not sure if that's a problem or not

That shouldn't matter. Is your header authentic, or a cheap repro?

tigasTT

fake..is it just better to return it and not even bother trying to install it even with the new rad/fan ?

Authentic what? All narrow headers are repros. RMF (sorry not AMR) went away many years ago. Also the original RMF narrow was noticeably different (and not exactly bolt-on) when compared to replicas.

Real RMF Narrow. Note 1 piece with collector angled downward which provides even better ground clearance. Also has rear hanger bracket, and 3-bolt flange that doesn't bolt up to OEM cat (no doughnut gasket).

Thanks for all the pictures here esp the radiator fan mod.. @Marc-111 changed my radiator to a 3 core with slim fan and the header went fine no problem.. Thanks everyone!
