Thread: VE and Log Manifolds

95+ have internal coils too, though it looks like 97.5+ require different spark plug wires then earlier models, thus I can see some distributor changes happening then.



You can find them used or buy them brand new from Greg V. Brand new will cost you a pretty penny though plus you have to wait couple weeks (overnight parts from Japan doesn't exist )

You can also buy a brand new VET manifold, though your gonna save a ton of money by going GTiR and porting it out, or even getting a tubular manifold.

I'll PM you some videos



What I learned from my log adventure, there are a lot of trade secrets and no one wants to spill the beans. Thus I'm doing my own research and make it public and well document with pics.

this is so false its simple science my man

Some is, some isn't, especially to novice folks.

X2. Very common denominator with the people who have good or great running logged VE's, they have visited a dyno spent time on tuning.

Like it's been posted again and again, get it tuned by someone who has experience. Probably would have saved yourself time and money if you would have taken it to get tuned by Jaime who is not very far from you.

Lol @ Trade secrets.

I see plenty of manifolds with black exhaust half circles on them (from where it was blocking the exhaust runner flow). Most people just look over it, just think it should fit perfectly.

My log didn't have that since I shaved mine down. But I did have two other parts that could be leading to flow restrictions.
1. T3 flange opening on the manifold is slightly bigger then the turbine housing.
2. Next one the bump right before the T3 flange, this one would probably be another flow restriction


I did work with Jamie a bit, he even said there was something else wrong (since I was seeing knock at even fairly low timing). I would have kept on tuning it and probably taken it to JKTuning, but turbo itself died so decided to go different route with the manifold.

If activating the cams would make any power bump (not loss) at even 5k rpm, I would think it's a tune. But our experience seems to be similar to this guy.

Now I wonder why Nissan decided to make low overlap cams for stock VET's. The VET manifold should flow better then GTiR ones too.

Wow, if the ports were really that mis-aligned... I made a hellova good power number lol. 442whp on 24psig VET cams with the .63ar housing with NO TUNING.

It's amazing, the car makes around 400whp on wastegate pressure now lol.

Nah, but I'm pretty sure the ports lined up on mine. The reason the soot is there is because I was using a DE manifold gasket that I ported out to line up. So there are soot deposits where the manifold and gasket didn't align completely.

But I will admit I could be wrong. The ports could have been off, but not by a lot. The manifold was using a VE flange.

i would not use a log design manifold on a ve head
those log design manifolds belong on diesels not turbo charged petrol engines

yeah log manifolds are soo outdated. While they make for nice simple easy fitment they just dont flow near as good as a tubular manifold. Hell Id rather have my cheap 100 dollar ebay rwd SS tubular manifold than a Log, which is why i went that way. lol. And im sure it made alot better power. Well I take that back, I know it made a lot better power.

That rwd mani made the turbo sit higher and more towards the center correct? Any hood clearance issues cause I'm thinking on doin the same?

ass dyno need recalibration
