My point was that VQ35 headers could be used. Whether or not the OP decides to use them is another story.


OT: Based on dyno evidence the A33B VQ35 made more like 245HP/265TQ. Same as the L31 altima. The extra 15HP that the maxima supposedly had was marketing hype.

This paragraph is making it seem as if I stated that the stock A33B units are better than the VQ30's. I never said that. At this point, my point is moot, so I will just let you fellas carry on.

 

he is refering to this:

 

scrhale's post was talking about the intake manifolds.

made in china's post was talking about the exhaust manifolds.

 

READ MY PREVIOUS POST. i DO NOT want a full 3.5 motor in my car. I DONT CARE if you and all the people you know swear by it like its the gospel truth fresh from the burning bush. this thread has gon from me asking a few questions that had not been asked about this setup before to a full out debate on why I SHOULDNT do this swap. as i said before, im not out to impress anyone, all i am doing is choosing one of the many options for performance that we finally have available to us. and yes i am on a strict budget. thats why i asked the specifc questions that i asked.

NmexMAX,nismology, Made-in-china; thanks for clearing the air on some of the questions that i had. if anyone else has anything to add in regards to THE HYBRID MOTOR SWAP please chime in.

thanks.

thanks, the last two i had seen before but i for some reason couldnt find them.

 

Go for it, it's a simple cheap swap you can do in one day . Being that you have all the parts ready.

I'm not exactly sure what the difference in power is with the 3.5 cams vs 3.0 cams but I used the 3.5's and with a simple SAFCII tune. I got to tell ya I had mad fun with my Hybrid just ask gtr_rider or 95blkmax they were all there when I spanked an RSX S 6spd that I believe had IHE. I had a terrible slipping Auto at that race. I also believe Tilley also mentioned there was a wider range of TQ under the curve with the Hybrid. I can sure as heck agree to that.

 

ok. thanks for that. ill be keeping it simple by just using the 3.0 cams. i imagine that this is going to be fun after i have finshed.

 

More simple? Not really. All you have to do to use 3.5 cams is slap on some spacer/adapters. Cheaper? I suppose.


There are really no advantages to using 3.0 cams that I can think of. Almost 1mm less lift and 6°/8° less duration in/ex. Please don't do it.

 

I'm finding that hard to believe.

Just to make sure I'm clear on this, I'm not comparing the Hybrid to a full 3.5 setup but a 3.5 on a 3.0 Ecu.

In this case they both have the same stroke of 81.4mm but the compression says it all. The higher the static compression the more powerful the explosion.

Hybrid 11.5:1 comp

EDIT: VQ35DE on 3.0 ECU 10.4:1 - 5.5gen 10.3:1





EDIT:

In general the Hyrbrid does have an edge down low but up top in the rev range the VQ35DE on 3.0 ECU should benefit allot more.

Only if we had a dyno graph of the Hybrid setup, that would be real nice to see if it's even worth the effort.

 

what are PROs and CONs of doing a hybrid swap as appose to a full vq35 swap, i have a 98 maxima and i'm gonna be doing the full 3.5 swap. i have a s-afcII, and got it tuned with the 3.0, wont that make a difference since i'm using the 3.0 ECU with the 3.5 motor?.. i have a 95 spd ECU to send to JWT later to get it really running good.

 

JAMAICANLOVRBOY: There is tooooo much info for me to stand by and not say anything about you looking up info for yourself. Do you need some help with using the search feature?

 

so much info, and different opinions. i'm gonna just do the 3.5 swap, run my S-AFCII A32 ECU for now, and later get the jwt programmed ECU. i have a y-pipe, and stillen 2.5" catback, that should be good for now. i cant find a good set of headers, most companies selling y-pipe header combo.(98 maxima 5spd)

 

Uh cattman sells a good header/y combo...ebay is not the only place to resource parts.
