All my transmissions were "recently put in"... lol... I think that hitting the rev limiter before a shift could complete hammered the tranny and screwed up the 1-2 shift. That's what happened to the previous one, anyway. These 2001 RE4F04W transmissions seem more fragile than the 95-99 version - and this one has a Level10 VB, too. It used to have a tight 1-2 shift. And yes, I'm hard on parts. "if you ain't breakin' sumthin, you ain't racin' " Truth is that my car gets more street action than track action. I'm a charter member of the nighttime "have a Mustang for lunch" club.

I'm saving up for a built transmission, for sure.

Something aint right harold, these autos arent that weak, on my previous i used to hit the limiter constantly. how big is the cooler u have?

grey99max

iTrader: (12)

I have two BM 16,000 coolers mounted up front. And, I use Lucas Racing ATF SemiSynth oil. The oil is about 256 miles old - and looks good, no chunks. Fresh filter, too.

maybe the tranny coolers are too big and the fluid is not getting up to operating temp. Cold tranny fluid can affect shift also

streetzlegend

iTrader: (8)

How cold is it up there now? I have a 40,000 cooler.

Harold, maybe its that lucas stuff? I stick to the same old mobil 1, and keep eye on tranny temp so it dosnt go above 180.

grey99max

iTrader: (12)

I know the oil temp gets up to spec because the torque converter lock won't energize until oil temp is up. This is with 30*F outside air.

grey99max

iTrader: (12)

That Lucas stuff sticks better than the Mobil1 - lots less "friction modifiers" in the Lucas, intended for racing. It started off working fine, with 30,000 miles on it and the Level10 VB - now the 1-2 shift is crap.

Today it was 17* F. Sigh - winter is here. Time to get out the car covers.

hey just wondering when you got the vb done you reuse the old soleniods, get new ones or upgraded them too

grey99max

iTrader: (12)

They were replaced with new ones - and yes, I wondered about the A solenoid too. The 2000-2001 RE4F04B/W transmissions seemed to be weak and slower compared to the 95-99 trannys, but low mileage ones of those have been harder to find within 500 miles.

Ever since streetz said his stock intake made more low-end power than a SSIM, I've been wanting to test a stock manifold. But to make it more exciting, I researched the 2007-08 Altima intake by looking into the Courtesy on-line catalog, where I find that the LIM is for a VQ35DE! Hmmmm....

I found the upper and lower parts for $150, plus $20 shipping, and ordered them from a yard and got them today. One interesting difference is the change in the bolt spacing for the fuel rails. The injectors are the same as a 350Z or 3.5 FWD Maxima, but some work is needed to mount fuel rails. The rest seems identical to the earlier intake ports. The upper manifold is plastic, and is one piece with elbow. The TB holes are different spacing, and the elbow has divided passages like the aluminum elbow.

so you think it's a improved version of the dek manifold

grey99max

iTrader: (12)

I have this Holset variable-vane turbo, and I see on eBay that someone is selling one that has been modified for vane control. It looks like the Holset electronics have been replaced with a mechanical linkage and a vacuum solenoid, maybe. This approach could make it much simpler to control the vanes.

I dunno - I've never seen the insides of a 00VI intake. This manifold is really slick on the inside. I don't know how the two valves on the ends of the plenum work, either. I was going to mount all of this on my old ruptured 3.5, but temps are in the 20s and dropping fast tonight, so this may have to wait.

Quite a bit of interesting info in here, thanks for the read. New to Maxima land, still learning, but I've been spraying cars for awhile now.

On a side note, have you tried Redlined or Amsoil ATF? Myself and quite a few people I know have had good luck with Redlined and Amsoil.

Thanks,

Something else to consider is a "money maker" style setup like Nitro Dave (and a lot of others out there) have had good luck with. Very stealth, great distribution, not *quite* direct port, but close....and much better than anything pre-TB

Here is a forum entry from my350Z.com, with dyno tests that show the change in WHP with changes in temperature. Look at the seventh post down, by Hydrazine / Motordyne Engineering. These numbers are a great argument for pulling intake air from outside the engine compartment.

This is why I'm looking for a plastic intake manifold. I also expect to insulate the LIM if these parts will fit - maybe something tough, like the Duplicolor spray-on bedliner stuff.

Hey Harold, do you run at the import faceoff events?
I'm gonna run in the all motor sport class this year.

Hey - yeah, I try to make the Import Faceoffs when I can. Mostly for the girls.... You probably know this, but if you go to their website, you can check the winning times for all classes for all events. Probably not the spring events - won't be done with the car by then.

Your Max will look good there - which ones are your going to?

Nitrous outlet, eh?

t6378tp

iTrader: (69)

when do you think the car will hit the dyno or track for atleast a n/a pass

grey99max

iTrader: (12)

When? I dunno... I've got to finish the Greddy EU installation, locate a core tranny, and get IPT to build a transmission and get that installed, first. Probably early spring for a dyno test-and-tune day... I'd like to have the direct-port systems ready at the same time, but that's more work and expense that could wait.

I don't have an indoor garage space that I can use, so our winter weather stops me doing any serious work for 5-6 months of the year. Today it was -3*F to start off the day. That keeps the 10 " of snow from melting. Brrrr...

time for a car port, LOL

No place to put one..... the yard is sloped down from the garage side of the house, with no level space available. I keep looking for a good service station with lift to rent, but everything is way too expensive or already rented. A buddy suggested buying an enclosed big car hauler trailer and parking it out front and working inside it, but I'm pretty sure my wife and neighbors wouldn't agree. I thought that if a neighbor's house burned down, I could buy the lot from the insurance company and put up a Morton or Star building next door - so I'm waiting for a fire....

I'm about 90% ready to get started on my own direct port setup. I'm just waitin' on my extra intake manifold and a distribution rail which I had modified come from Nitrous Outlet. Waitin' on a response from Chris as to why it's taking so long.. sigh. I should have just gone with a local speed shop and had them drill the rail. I would have been able to tap it easily. So far this thing has been nothing but delays. Once I get some time to start.. I'm side tracked. Like now I'm working on getting my friend's nitrous setup into his Civic. Yet another setup I have to worry about.

So Guess you never saw this thread.

http://forums.maxima.org/all-motor/3...altima-im.html

And more specifically, post #58

http://forums.maxima.org/4853809-post58.html

Spacing of the heads are a little off. (among some other minor differences) I'm sure, it can be made to work with our heads with some machining though. But not worth it IMO. The TB is different (smaller if I remember correctly) but you can obviously make an adapter plate for a PFTB.

Also, we've done a motor swap already down here using the 07+ altima motor with this IM. And its not that impressive at all with static cam timing. But thats not the IM's fault of course.

Good luck.

iTrader: (12)

Thanks for locating that thread - I hadn't seen it. I took some more photos and measurements tonight. My reasons for pursuing this manifold is that I'm looking for more air flow into the Cosworth CNC heads, and this combo may do that. All ports are larger than the Maxima/350Z LIM and the SSIM UIM parts that I have here.

Notice that the Altima LIM ports are spread out a bit:


But the port and bolt spacing is the same..


A closer look:


The old ports are 47mm round and 42.7 x 45.6mm - LIM head port is 39 x 45.1mm.
The new ports are 40 x 48mm and 40.1 x 47mm - LIM head port is 39 x 50.4mm.

grey99max

iTrader: (12)

I'll take it apart.

The TB opening is 71mm, compared to the old 72.9mm....










Down the rabbit's hole:

grey99max

iTrader: (12)

The base of the Altima is too wide to fit on the stock bolts. Roughly 5mm....







I think there's enough metal at the base of the LIM to cut it down quite a bit, but I think that the injectors' holes will have to be relocated closer together. My machinist should be able to handle this - but I'll ask. If the LIM can be made to fit, then the UIM is possible, with a custom TB adapter to rotate my Pathy TB 90* and new hole locations. I have some 1" plexiglass for that. Might require custom fuel rails, too.

The LIM plenum looks to be larger, the ports are larger all the way through, and this combo should complement my Cosworth heads nicely. When I coat the LIM with bed liner goo, there won't be any heat absorbed from the engine compartment.

So far this is promising...

bamboomerang

iTrader: (14)

Thanks for the detailed pictures. A small request: are you equipped to get those studs off the heads to see exactly how it sits? A couple of mm's of machining is nothing, and the fuel rail isn't impossible to find (sub 100$ new), looking verrry promising.

grey99max

iTrader: (12)

Yes, I have the sockets to remove the studs (done it before) - but it's 11*F here (9" snow yesterday) so this project will wait for warmer weather. I'm pretty sure that the LIM can be machined down to fit the older VQ35DE spacing, but the injector holes may need to be filled and re-machined to locate them correctly. If I can get the injectors spaced the same, and get new mounting points put on the LIM, stock-layout rails should work. My AutoGear rails are not cross-connected, so that makes it easier.

If all the work of switching over to the '08 manifolds just requires machine work on the lIM and a new TB mount on the UIM, I will be pleased. Really pleased.....

Something to keep you working:


Now I just need to get the jets in, figure out if I wanna stick with dual nozzles (in the neck) or go direct port for the methanol and mount all of this onto the car. 150 shot here I come!!

Yes, I know, I'm missing a nozzle. Don't ask. A replacement is coming.

grey99max

iTrader: (12)

Yes! This is great. Nice choice of rails there. Do they come undrilled? Do you think you can get two stages on the aluminum manifold using those parts?

I think that you used 90* nozzles instead of annular nozzles - why was that? I was planning on keeping everything out of the airstream in the ports - but that may not make much difference. Again, great job there.

2002AltimateV6

iTrader: (7)

My concern has never been disruption of airflow but rather getting the proper atomization/mixture of nitrous/fuel and oxygen in the intake. The way that nozzle comes out it's right on top of the intake valves. I wanted it as dead center in the intake path as possible.

The singular rail is only good for a single stage, but you can use two rails. Or just buy the two-stage NX nozzles and run dual rails. Now that would be awesome.

grey99max

iTrader: (12)

What nozzle are you using?

2002AltimateV6

iTrader: (7)

Dynotune.

grey99max

iTrader: (12)

Today I pulled the four studs out of the heads and put the Altima LIM on the old 3.5 engine.

On the front side in the LIM, the manifold contacts the heads on both side. Some grinding will be required.








Notice how close the injectors and bolt holes are to lining up.
