typhoone Posted January 13, 2007 Share Posted January 13, 2007 I am sure some people are getting sick of me posting, and for those people i am very sorry but i am doing my best to make sure that i have everything planned from the very beginning of my build. Just wondering, i have little to no skills when it comes down to welding etc and i was wondering if any member is willing to or knows of a company that can gut my intake plenum. I read that it can add up to 8% hp and if manage to get up to 300 hp, and extra 24 peak hp is more than welcome. So, please let me know if someone can do it or if i will have to find someone around here and PRAY that they don't destroy my plenum. -Typhoone Quote Link to comment Share on other sites More sharing options...
mtcookson Posted January 13, 2007 Share Posted January 13, 2007 These guys do it but it is pretty expensive. http://www.lpperformance.com/ Quote Link to comment Share on other sites More sharing options...
Guest Sharkracer Posted January 16, 2007 Share Posted January 16, 2007 Ever heard of Extrude Hone? I always hear good things about them in other car forums. They push abrasive fluids through your manifolds and it bores it out. http://www.extrudehone.com/afmpro.html Quote Link to comment Share on other sites More sharing options...
typhoone Posted January 16, 2007 Author Share Posted January 16, 2007 fun stuff. i'm not really looking for boring, but more of gutting. welding the fun stuff shut and all that. i looked at www.lpperformance.com and it seems interesting but they don't have the dyno numbers up yet....and it really is EXPENSIVE Quote Link to comment Share on other sites More sharing options...
Guest Sharkracer Posted January 16, 2007 Share Posted January 16, 2007 Boring, gutting, same thing. Did you read the article? It takes away material from inside the plenum. This is the only way to do it without cutting open the manifold. Quote Link to comment Share on other sites More sharing options...
typhoone Posted January 16, 2007 Author Share Posted January 16, 2007 ??????? I thought gutting was taking out the extra stuff & also welding some stuff shut....someone correct me if i'm not on the right track. I thought boring was something totally different. :-/ am I dumber than I thought I was???? Quote Link to comment Share on other sites More sharing options...
Comrade_Charlie Posted January 17, 2007 Share Posted January 17, 2007 boring. think drilling a larger drill bit into a smaller hole. for the welding stuff, probaly just a block off plate for some emissions stuff... Quote Link to comment Share on other sites More sharing options...

NissanSportMag(Z31) Posted January 29, 2007 Share Posted January 29, 2007 Extrude honing will simply smooth out the internals and remove the rough parts. It won't actually remove too much material. I've seen 4 different companies do the plenum gutting, and they all charge roughly the same price, about $400. The gutted plenum is actually larger in size internally. But there is still the issue of the smaller elbow after the throttle body. I'm not sure if any of the companies actually smooth that area out or enlarge it as well. The flow data isn't dyno numbers, but it will give an indication of what to expect. http://redz31.com/pages/plenums.html Quote Link to comment Share on other sites More sharing options...
300zxt Posted January 30, 2007 Share Posted January 30, 2007 MGP are working on a gutted maxima plenum, which has the tb towards the front and does away with the elbow... I'm kinda shat actually cuz I would of gone that route if it had been available earlier. http://www.mgpautoparts.com/guttedPlenum/Maxima/maxGuttedPlenum.htm Quote Link to comment Share on other sites More sharing options...
mtcookson Posted January 30, 2007 Share Posted January 30, 2007 I'm actually using that 2nd gen Maxima manifold on my 3rd gen and will likely be going with MGP's manifold down the road. It looks pretty good. Quote Link to comment Share on other sites More sharing options...
Comrade_Charlie Posted January 31, 2007 Share Posted January 31, 2007 I found a old maxima with a vg30 in it at the only "you pull it junkyard" around here, im taking the intake plenum this weekend or sometime soon... the place said 11 bucks for it, pimp. im not gutting it just going to use it as is... any thing is better than the stock one, and it doesnt have elbow. most likely it will sit in my room till I upgrade turbo and all that stuff... but I dont know if 400 bucks for a gutten plenum has a real good price to power ratio as apposed to cams or bigger turbo or w/e for 400 thats engine crap. unless you have all that then go for it.
