Guest dan4011 Posted September 19, 2006 Share Posted September 19, 2006 yea i got a carbide bit on my dremel tool, it worked out pretty good, not as smooth as i wanted it, and not completely 60mm, but it deff should help. now i got to figure out how this idle screw on the weber tb works?..

81280zx Posted September 19, 2006 Share Posted September 19, 2006 sorry to go off the subject of the tb but wanted to know also if there are benifits of port mathing the intake manifold on a basiclly stock car but i do have the cold air intake on it but don't know if thats would help with the port matching also thanks all.

johnc Posted September 19, 2006 Share Posted September 19, 2006 Port matching is one of those low buck mods that helps other mods perform better. Its not worth removing the intake/exhaust/head from the car just to do port matching but when that stuff's off for other reasons, its another thing to add to the to-do list.

Cruez Posted September 19, 2006 Share Posted September 19, 2006 What 240hoke said... a good carbide tip makes quick work of it.. http://www.cruez.com/gallery/thumbnails.php?album=3 There are a couple pics there when I did my TB port matching.

HOLY GOD!!! That is a beautiful intake manny and damn you did a great job on it. I don't think I've seen anyone that has taken the time to remove the holes and smooth out the manifold, Im definitely going to do that when I get around to building up the motor.

JMortensen Posted September 21, 2006 Share Posted September 21, 2006 I think this guy wants to PORT his manifold, not port match it. I mean I guess you could call it port matching, but if he's going to a bigger TB it's not the usual 5 second shot with a sanding roll type of port match. He's talking about hogging it out to the 60mm. If I were to guess, I'd say that probably IS worth taking the manifold off. Quote Link to comment Share on other sites More sharing options...
Administrators BRAAP Posted September 21, 2006 Administrators Share Posted September 21, 2006 Okie dokie, just one more… This one, installed on my partners L-28ET with the engine set WAY back in the chassis, shown here in its raw aluminum stage just prior to getting ceramic coated.

veritech-z Posted September 21, 2006 Share Posted September 21, 2006 I wanna play this game too! Not as pretty as some of the others, but that's what wrinkle finish paint is for! Quote Link to comment Share on other sites More sharing options...
nismofiend Posted September 22, 2006 Share Posted September 22, 2006 Wow you guys make my fab work look like total ♥♥♥♥. Im guessing the only option to do something like this is fill it in with aluminum welds correct? What are the chances of a local welder doing the fill work for me since I don't know how to weld aluminum nor do I have access to what I need. Anyone have a rough estimate as to how much they might want to charge to fill in the welds? (don't want to get screwed and would like to know if I come across a good deal) Other than that I would just need an angle grinder right? Edit: Also I have the N47 head on a 79 ZX, would I be able to grind out the webbing on the intake manifold or is that a no no. Quote Link to comment Share on other sites More sharing options...
veritech-z Posted September 22, 2006 Share Posted September 22, 2006 You don't actually need to weld it in, not many of the holes go all the way through. Braap did a write up some while back explaining how he would use pipe plugs in the hole, and then grind them down. I didn't do that, I just ground it down, and the spots that were really low I used JB Weld like it was bondo, and then wrinkle finished the hell out of it. I chose to leave my vacuum ports on top, instead of moving them to the bottom like a lot of the guys did. Quote Link to comment Share on other sites More sharing options...
sweetleaf Posted September 22, 2006 Share Posted September 22, 2006 Wow, BRAAP . That engine is set far in. Going for the mid engine huh . lol Did you totally reconstruct the firewall on the inside?. Got any more pic's of that.. Quote Link to comment Share on other sites More sharing options...

I chose to leave my vacuum ports on top, instead of moving them to the bottom like a lot of the guys did. As Veritech stated, the intake I first pictured, (gray one with the 60mm throttle valve as used on our race car), I did tap the holes and installed brass pipe plugs, ground them down, filled all divots and crevices with JB weld, then just painted the manifold with “Cast Blast” paint, color is cast Iron gray. (see the “in process” pics below). The intake pictured in the mid Engine Z project had all of its holes welded so that it could be ceramic coated. I am currently modifying another N-42 intake in the same manner for ceramic coating, but minus the throttle linkage towers and machined for O-ring injectors like our Race car intake.

nismofiend Posted September 23, 2006 Share Posted September 23, 2006 Sweet thanks guys but drax240z isn't that the picture in the tech tips section of atlantic z car club or did you take the picture and they use it? Either way they spelled "original" wrong on their version lol. Quote Link to comment Share on other sites More sharing options...
Administrators RTz Posted September 23, 2006 Administrators Share Posted September 23, 2006 That engine is set far in. Going for the mid engine huh . lolDid you totally reconstruct the firewall on the inside?. Got any more pic's of that.. That car was never finished... got 'traded in' for this... I still have the chassis, though. Been kicking around the idea of resurrecting it. Needs significant structural work as the cowl became very flimsy. You can flex the windshield quite easily.

nismofiend Posted September 23, 2006 Share Posted September 23, 2006 That looks like it would be a total bitch to work on at all though. One of the main reasons I like the L6 so much is because of how much extra room is in the engine bay and how accessible everything is.
