JCR Posted April 26, 2011 Report Share Posted April 26, 2011 trying to pull all the smog equipment off the green bean the L20B motor needs a new exhaust manifold I was thinking about a L16 manifold but I am hearing that the L18 may work also anybody have an extra manifold I really need one please let me know Quote Link to comment
Z-train Posted April 26, 2011 Report Share Posted April 26, 2011 All that's connected to the exhaust manifold is the EGR.There is no advantage to disco'ing the EGR. Quote Link to comment
banzai510(hainz) Posted April 26, 2011 Report Share Posted April 26, 2011 I have 2 square port L16 manifolds but not will ing to ship. Tope End Performance sells a short tube square header but needs to be ceramic coated also. You never said what head you have so it could be a round exhaust port. N Carlilina isnt a Datsun haven for parts. Quote Link to comment
JCR Posted April 27, 2011 Author Report Share Posted April 27, 2011 I know there are not a lot of parts why not ship ? and I removed the intake and the exhaust so it was not just the egr i was trying to get rid of the intake and the exhaust are mated together that is what i am trying to get rid of ....alog with the rest of the smog crap and i have a couple of shots of the block i think they are round check the link datsun block Quote Link to comment
datzenmike Posted April 27, 2011 Report Share Posted April 27, 2011 If your truck is a '75-'77 then it has square exhaust ports. This exhaust is used with a U67 square exhaust port head. Quote Link to comment
JCR Posted April 27, 2011 Author Report Share Posted April 27, 2011 not doubting that you are right but they "look" round I could be wrong ...... I will check and see if I can find what block I have Quote Link to comment
JCR Posted April 27, 2011 Author Report Share Posted April 27, 2011 GRRRRRRRR!!!!!!!!!!!! this started as a simple carb replacment and got out of hand I just need an exhaust manifold that will fit my motor somebody out there HELP me out Quote Link to comment
datzenmike Posted April 27, 2011 Report Share Posted April 27, 2011 Well it's your head is it round or square exhaust? The manifold you have there is for a square but the head could have been swapped. Look behind the fuel pump between the #1 and #2 plugs, the head ID will be there. This is a W58 and would have round exhaust ports.. . Quote Link to comment
JCR Posted April 27, 2011 Author Report Share Posted April 27, 2011 u67 and they ARE square Quote Link to comment
datzenmike Posted April 27, 2011 Report Share Posted April 27, 2011 Then an L16 will work. L18s sometimes have an EGR tube but you can cut and fold over or put a metric pipe plug in the hole. You will need a new intake too... the one you have has a hole below the carb. L16 intakes do not have the EGR valve on them, L18 probably will depending on year but the L20Bs ('78 and on) are the largest runner size but will have EGR valve. Quote Link to comment
JCR Posted April 27, 2011 Author Report Share Posted April 27, 2011 thanks now if I can just find one have the intake already but really need an exhaust Quote Link to comment
Llittle_Llama Posted April 29, 2011 Report Share Posted April 29, 2011 I have one, 75 shipped and it's yours. It's the non EGR manifold, exactly what you are looking for. Paypal: kobellama@ymail.com Quote Link to comment
