Ported gen 3 it is then. Know where I could get one besides clubgp on the cheap? I see zzp wants $350 and wbodystore has them for $280. And geez $450 at Intense. ZZP's looks the best, wbodys looks very good and Intenses looks like crap from the pics. Looks like I'm goin with the wbodystore one. Would it be worth it to find a ported LIM as well?

 

The whp difference isn't that big, and some people are less sensitive to mods than others. I've seen people do a ported gen 3 and a tb at the same time, and not notice much difference at all. Sure the car dynos higher, and runs quicker, but I don't want him thinking it will be like adding a turbo or something. The gains are there, but not everyone thinks its a sizeable/very noticeable difference.

I'd just do whichever is cheaper myself. I'm sure a ported gen 3 would be cheaper, but I've heard of some hella deals on gen 5s from people who don't know what they have. The gains should be roughly the same between the two if thats all you did.

The only way it would be beneficial is if you get a blower where they machine out that divider wall under the blower (separates the blower outlet rectangle from the area where the undersides of the needle bearings are). A lot of places machine that area out to utilize more of an intercooler core.

If you're not running an IC and don't port the inlet of the LIM, then you'llcause some turbulence right there- I've always thought it should be an optional thing. The good thing is, its pretty easy to open your LIM up yourself. When I did mine, I just used a jigsaw with a short metal blade and an SOS pad strapped underneath (so it didn't scratch)- it cuts out pretty easy, then you just need a dremel or something to cut the supports out. You can use a s/c gasket to match the new outlet to the LIM to make sure you cut the hole right.

An outlet port on the LIM would be a waste for you, and would hurt more than it would help since you have stock head ports.

 

Sorry that is a little fuzy for me. The wbodystore ported gen 3 does have the divider wall removed and I won't be running an IC, so I do want a ported LIM or I don't? I don't have any tools so I would be buying a ported LIM. So I would be ordering THIS and THIS right?

 

To be honest, that little divider makes very, very, very little impact. Everyone says it does, but no one has yet to prove the difference. I would go with a ported Gen 3 that has that divider still in there. If you planning on trying to throw down MAD power, then it might help, but honestly, save your money, keep your LIM, use a ported blower with the divider still in there, and then work on rockers, a TB, tuning, and eventually, smaller pulley. =)

 

I'm not trying to confuse you, but honestly, it's your money, and you AREN'T going to gain any REAL WHEEL HORSEPOWER by wasting your money on a ported LIM, ya know? Just trying to save you money, and still get you the most bang for the buck =)

 

I would do a machined intake (or cut your own-a cheap jigsaw is only like $20) with that blower- just because you'd hate to have the blower open up to use a larger outlet, but then have to squeeze back down into the stock LIM opening. They extend the outlet a little further forward too- so you'd have the same issue up front, even if they left the divider.

Honestly, I haven't seen too many vendors leave the divider wall that doported blowers- I guess they are all optimizing for an IC (in which case it makes a difference).

I dunno- if he gets a blower with the divider wall removed, and where they port out towards the front an extra 3/8" or whatever- I'd think the turbulence caused in those two areas wouldn't help flow much.

 

It's actually cheaper to get the ported blower without the divider. And then I might as well put in the machined LIM while I'm in there. My thinking is that I'll already have it tore down anyway so why not? Money's not really an issue, I mean I was considering the Gen V which would have been twice as much. And while I'm switching out the throttle body I might as well put on a ceramic crossover pipe. I just want to do everything at once and do it right. I want to be able to run a 3.4 pulley easily, I'm thinking after these mods and a dyno tune I should be able to. Maybe one day in the very distant future I would like to put in the s1x cam but hey I should get this car paid off first before I go blowing it up.

 

I'm definitely not trying to stir the pot, but prove it.

NO ONE has presented information that it's worth the money to have that extra wall CNC'd out. I don't have mine done. I have an IC, and all that happy supporting mods, and still have 336 WHP. And that is with a 3.1 pulley and moderate timing (so as to not to kill my mileage.)

Like I said, not trying to stir the pot, but people on Club GP make these statements too, but have nothing to show for it. Do a monte WITH it removed, and WITHOUT it removed, with the same mods otherwise, do a dyno pull with the same tune, and then see if it's worth it. Doubtful. Especially with only a 3.4.

Either way, I think it's still a great idea to go ported housing NocturnX, and if it's cheaper in the long run to go Ported LIM, make SURE you only get the INLET ported. The outlet will cause incredible performance loss if they're not ported to match ported heads.

And to be honest, you may want to consider both front and back exhaust mods, I.E. Headers. When I did my TOG headers, before all of the mods, I noticed a great power increase, and DECREASE in knock.

Where ya gettin her tuned at?

 

I'd go to Intense for the dyno tune, 20 mins. from here and I hear Brian is the man at dyno tunes.

I already have 3" downpipe and Plog, so I think I would be out to much $$$ to switch to headers now. I hear bad things about every kind of headers for the 3800, pacesetters leak, etc. Plus I would have to pay mucho deneiro to have headers installed. Maybe I will consider headers again when I am also considering a cam.

I'm pretty sure the zzp machined LIM is inlet ported only.

True. Although I did headers myself, it was a pain, but worth it... HOWEVER, for the time being, you're correct, headers AREN'T needed..

Let me know how they tune. I'm curious to see what they can do.... I don't think a single person on this forum has gone to them yet... I think I'm one of the only on this forum for ZZP dyno...

Keep us updated =)
