I have a 07 tls 5at, it's pretty much fully bolted (pcd,aem v2, v3 j pipe, custom cat back magnafow mufflers, plenum spacer from odesy/ridge line, TB Spacer) that leaves me with these two options. I realize that both would be the logical choice but as of now I only have funds for one or the other. What would yield most bang for the buck. I see most dyno pulls from 3.7 mostly benefits from 4K up. After I been driving my 350zde I just love the bottom end midrange pull of that motor. Like to hear feed back from you all that have done these things and what you think,

I'd go w/ the manifold if you're on a budget. Hondata is great & all, but too much $$$ for a performance upgrade when really it doesn't yield that much HP gain; its mainly used for better responsiveness from the car. I wouldn't buy it unless you're going FI.

Hondata since you can always retune for more power with additional bolt ons, or if that is too much for you. Kturner is 200 dollars cheaper for the v1 and the same as hondata if you want the lcd

I don't have the Spacer or PCD and I am a 6MT, but my vote is Hondata or Ktuner, tuning solutions often get overlooked on our silly FWD N/A cars.

I picked PNP runners and intake over swapping to the 3.7 intake.

however; you cannot change the engine's characteristics...
the Honda's engine is made to make peak power up top! I believe 6700 RPM is peak power.
so, you will never get the lower end torque you want unless you go F/I

hondata...it changes the way the engine performs, gives you a knock free engine, allows all your mods to work together efficiently, and adds 10hp on top of that. yes it's not that much hp but it greatly improves the driveability of the car. everyone that has questioned it and then eventually got it said they were dumb for not doing it earlier. plus there is a great tuner on here (his name is dom and he tunes by email) that will give you a lifetime tune which means if you do add the 3.7 in the future, he will retune for free! can't beat that deal.

and hondata is definitely not just for forced induction that's silly

ExcelerateRep

Another vote for Hondata! (or Ktuner)

As mentioned before, it will allow you to pick up some extra horsepower from all your bolt ons, and it really does help with drive-ability; it also sets you up so you have more room to grow down the road. This way if you ever went forced induction or something along those lines, you have one less thing on the list!

We have it on our site, along with Ktuner. You can compare them here:

Good luck and happy modding!

The logical choice if you're planning on doing both eventually, is to do the manifold first. That way you only have to tune once after getting the Hondata, rather than getting Hondata, tuning, then later adding the 3.7 manifold and having/wanting to re-tune. I made solid gains switching to the TL-SHAWD 3.7 manifold, Max Bore ZDX TB and ported runners while I was still on stock ECU with no Hondata. Then I bought the Hondata and the '08 Type-S ECU and brought it all together with a solid E tune by Vit.

LOL thanks guys! This doesn't make it any easier! anx1300, what kind of gains did u see with your 3.7 swap???. I know top end is improved what I've seen on dyno results is about 7hp. But how did the car feel over all? Idle to reline?? I know this motor likes to rev...... does the k tuner alow rev limit changes? Also is it even worth(safe) to increase? The but dyno tells me yes. Almost seems as if the car runs out if rev than power. Dynos I've seen from memory looks flat al the way to limiter. I haven't dynoed the car BUT. What I have done is a lot of 1/4 mile runs. Trapped Best of 103-1/4 79-1/8
14.1 consistent. So it is making some power. The only thing I haven't tested is the spacer. Let me tell u guys this mod is probably my favorite next to pre cats. It's woke the car up big time from idle to VTEC. I've read that takes away top end but I'm not 100% sure on this one...... maybe it feels like it because midrange wakes up a good amount that it doesn't feel like? Only dam thing I don't like is how high the intake sits now and the washer mod I had to do. I took it off just to verify feeling. YUP went right back on. It actually spins the tires far better that it does without it. I'll test it this Friday see how/if it changes anthing. Biggest nemesis for the TL at the track is 60ft. Best 60 always been in the 2.2 range. I don't expect a lot because the 14.1 run was in 55 deg weather and we know how temperamental this little B*^#h is in the heat!

Ok just ordered the manifold TB combo. I'll do the hondata in a couple months. Went to track last night and was extremely happy with the results considering the hot humid air.
1st pass hot off the street she went 14.5 @99 I was very surprised in the past in similar conditions she would go 14.7 14.8. I iced intake 30 min went back and ran a whooping 15.3 LOL. This shocked me I have NEVER had traction issues before, the only diff I've done from my 14.1 50deg weather was the mdx spacer. Went back lined up again this time I heated tires and bam 14.2 @101 followed by a 14.3 right after. One the third pass I didn't heat tires and it spun but not nearly as much after the 30min cool down. I have read that the spacer takes away top and lookin at slips it may be true. In the past without it it's gone 102-103. It may just been the conditions couple guys where complaining there cars where slower last night. If that's the case she only went half a tenth slower from 50 deg weather (14.19 vs 14.24) but down 2 mph that's the weird part. Comparing slips last night it was quicker 60ft 2.24 vs 2.28 cold weather and 6.09 vs 6.10 330. But the top end is better plus mph without spacer.
Not a good comparison with 30deg air temp. But considering how bad air was she ran dam good! I'll bolt on the shwad manifold next weekend with spacer ad head straight to the track with only change the intake TB.


Who here can port the lower intake runners I have an extra set??? Or links vids on how to do it myself??

Andy Gerzand ports runners. Hit em up!

P2R has sets that are ready to go. He will also give you money back for cores

mr600r

WOW! Those look sick! Read there even better than prior versions. Ok DONE just placed the order so I'll be bolting on all three, Shawd man/Tb and ported runners. Will/should port the spacer or intake? Also besides gaskets what else am I going to need to bolt this up? Prediction on power gain? I've read 7-8 gain on intake alone, I'll go straight to track to test. Mph is my measuring stick so 1-2 mph would amazing to gain. CANT WAIT. I've been after these runners for a while so glad they brought back

there's been threads and dynos that show that the intake manifold spacer AND PnP runners reduces your gains as a heads up. it's either one or the other, i think i read that both increases the air flow to a point where there is turbulence that hurts gains (i think they did a benchtop air test and a dyno)

thisaznboi88

iTrader: (7)

Get hondata or ktuner. Problem solved

mr600r

WOW that's a hella nice gain. ALL the way across tach! Was that a dyno tune or ETune? That's impressive. Yea that the very last thing to get is a tune using one or the other. Soon as I get these parts in a bolted up I'll head straight to the track and see what it gains in MPH. I emailed p2r they didn't say anything about turbulence issues, pretty much what I experienced already with and without spacer. For the street he recommended keeping in on. Did say I didn't need to port/polish the other two, it would be better but not anthing I would feel, so I'll just bolt all the parts up when they arrive

That was from a dyno tune.

As for the p2r spacer you won't have any issue running it with ported runners. I think the whole issue with ported runner and ported mdx spacer was when people were getting it milled they milled the wrong side. The mdx spacer is tapered and what I think happen is that instead of milling the tapered side they milled the larger end. So the diameter actually got smaller thus messing up the air flow. the p2r manifold spacer are the same bore completely through. Just my theory, I have ported runners on my 03 pilot, but i didn't touch the spacer since I ran out of sanding bands. Didn't notice a lost of power. The suv feels like it is breathing better

mr600r

Dam the milling part makes sense, glad you told me that I was actually thinking about milling it, the only reason I wanted to do that is because of the extra height it made on the intake. I had to do the washer mod to hood bolts etc. but now the other problem is it rubbing against the hood liner and it's coming apart now 😒.
Ok IF I where to mill it down (1/4 inch maybe) what side is the one I'd ask to trim? The bottom half of top half.?
