Ok I think I've about made up my mind to try and do the mevi with my supercharger. However I do have some questions. First if I bought a new MEVI kit from http://www.courtesyparts.com/mevi-ki...ath=1783_5831&
what else do I need to complete the install besides the spacer that I would get as well. RPM switch controller?
How do the Cefios that came stock with these control the opening and closing of the VI. Also Would I need to redo my boost tubes or does the MEVI and the UIM have the same length and angle to the TB.

Is there a way to control the butterflies without tapping into my ecu? vacu. control or something?

I know everyone is going to say do the 00VI instead but I like the fact that the MEVI is a direct swap and I really like the look of it.

 

The RPM switch is what controls the butterflies.
What spacer are you talking about?
All you really need is the MEVI, a VSS, the RPM switch and a vac cannister with some vac hose.

 

I think hes talking about the NWP spacer.

 

Ah, but the Phenolic spacer isnt needed to install it.
I have them, and Im not too sure just how much it did to lower the temps.My manifold is still very hot to the touch, unlike what others have said.

 

Right, but he said he would be getting the spacer as well as the MEVI stuff.

 

Yeah I read that, but the way he worded it was as if the spacer was needed to complete the install...

 

no no I know I can install without the Phenolic spacer but I figured if I was going to do it...... So the VSS? and I saw a nissan vac canister on someone install does any one know the part #'s one that? How did nissan control the rpm switch orginally?

and +1 on the hot intake Mine was too hot to really touch today....as was the boost tube so I think an intercooler maybe on the way as well

 

Tons of info on this...

Your welcome

 

Screw the gm solenoid. Just got to the bone yard and get a nissan one, there on all the cars and readily available. While youre at it get a nissan vac tank and check valve. They are on a bunch of cars too, 99 Max, 3rd gens, any motor with butterflies.

I assumed the MEVI cars had a different ECU.....

 

You don't have to get a new ecu (or get yours reprogrammed) but it won't really do a lot unless you do. The VI starts increasing hp just before the stock redline. So, you'll start feeling the extra hp just in time to shift and wait for the increase again. Check a MEVI dyno and you'll see what I mean.

FYI: I bought one from Courtesy Nissan about a month ago as discussed here and the money was deducted from my account right away, but the MEVI has yet to arrive. I'm calling tomorrow to check the status of my order, so I'll let you all know what they say.

 

thanks all! and I did a search which is how I found out they used a nissan canister but I never saw the part #'s but thanks for posting them again

I hope they still have the mevi's
and as far as having the ecu reprogramed it would be nice however my car seems to blow through the shift points on the tranny now anyway I bonce off of the rev limiter at like 7200-7400 rpms all the time in first and second gear even with the auto and the mevi should still give me a nice boost in power as compared to the stock IM.

 

Wait, are you saying your car hits 7k before it actually shifts?
And I find it hard to believe your rev limiter is set at 7200-7400 unless its not a factory ECU.

 

im assuming hes going by what the tach reads, cuz we all know that thing is like atleast 500+ rpms off.

 

factory...Ive had it since new unless the dealer installed something different when the replaced the ECU and TCU this past fall after if got some water damage. It will go well into the red line before it shifts then starts cutting out. (but only in first and second when really pushing it) It really worried me the first few times it did it but it didn't seem to hurt it. but I did blow the boost tube couplers a few times by over boosting.

and yes I'm going by what the tach reads but after the flood damage I have had it hooked to an on board computer reading all of the ecu/sensor fuctions while riding in the pass. seat and the tach/speedo was right on!

 

Update: I bought a MEVI from courtesy march 28 and it came in yesterday! I didn't know if it would come because it says "out of stock" once you add it to your cart, but it still lets you checkout. So, yes, they do have them. I guess it just took a month to track down all the pieces from across the country. If you order one and you don't have it in a few weeks, don't worry. Mine took just over a month! But it's in my garage now and going in this weekend!

 

sweet!

 

Just as MaximaSpd85 stated, our tachs are normally off by 500rpms. Ive seen this on the dyno and when doing datalogs.
If you say your car has a shift point of 7k and builds power all the way up to that point using the USIM and factory ECU then you must have some sort of factory freak.

 

What I'm saying is it will blow through the shift points and it pulls all the way now it may fall off some of course but it is still pulling for sure right up until the tires lose grip anyway. The tranny will not shift fast enough it WILL over rev. I double checked this last night and it hit the rev limiter at 7200 rpm before it shifts in 1st and 2nd but it shifts at 6500 in 3rd so...I dont know what is going on there???

 

That sounds like slippage.

 

yeap....the wheels are spinning I dont hook up real well (at all) above 5800rpms but the tranny is not slipping. I have a fresh tranny with a shift kit.

 

you guys keep mentioning our tachs being off... You mean to tell me our tachs are 500 RPMs short when revving?

 

id say definitely....after a certain rpm. probably not as much in low rpms cuz think about, some cars idle at ~650, theres no way its 500 rpms ahead at that speed. but definitely up top, youd probably be able to rev it all the way to 7000 rpms before the 6500 fuel cut hits. with my 7200 rev extension, i had to take it all the way past 7500 rpms to actually get near that.
