Yeah, it's pretty fun! Kind of a pain past 70mph though. Either a T2T4 or an M2B4 with an aftermarket diff would be a better choice, honestly. This M2F4 was a screaming deal so that's why I went with it. The F23's torque makes pulling this pig around in just about any gear and any rpm pretty easy.

Intake on, egr deleted, and swapped to a no coolant JDM B20 IACV. Idles better. And pulls HARD as F to fuel cut at 6500. I think I'll be revving it to 7000 the way it keeps pulling. Zero loss of torque. Can't wait for Sunday.
See my thread in the Performance Tech/Naturally Aspirated section for details.Comment

Nice car you have there. I need a F23 block so bad...

Just do the whole swap! It's an awesome engine!
Well, results are in. Ported intake was worth some torque down low, about 10whp near Red line. Played with VTEC engagement and found it worked best around the factory engagement at 2400RPM. Gained an assload or torque under 4000RPM. Final run numbers were a little bit lower due to higher IAT's than the initial run, but you can see the old numbers, ported intake+old tune(crome), and new numbers(neptune). Not a big difference in overall peak numbers, but under the curve is sooo much better than before. 14's should be easy with all the new stuff done. At this point, it looks like the camshaft is holding it back.
With the M2F4's gearing, acceleration is effortless in any gear and almost any speed. I love having 140lbsft of torque so low in the rev range and keeping that much to 5500rpm. What an awesome feeling, this would be an absolute riot in a much lighter chassis.Comment

Is that with no tuning? I saw the thread showing just how much you ported out, but is there any downside to doing this? Usually people lose some torque down low when porting, but if I'm reading that graph right you did nothing but GAIN GAIN GAIN! Pretty awesome results, might look into swapping an F23 in instead of an H22 at this point.Originally posted by Chrisnick View PostComment

The results of this have me very tempted to do a straight F23A1 instead of a F22/F23 hybrid like Gary has done. This thing is a straight up torque monster all on it's own. I already have my F23A1 laying on the bench fully disassembled. So it wouldn't be hard to start working on it later this summer. Your results are absolutely awesome man! Keep up the good work!

I meant if he had adjusted his tune in any way, since he mentioned stock VTEC was perfect. However, I derp'd and missed the switch to Neptune from Crome. I'm curious how much of a change he had to make to his tune then, besides the whole switch to a different program.Originally posted by oni_cb7 View PostComment

They're pretty close to the same settings, maybe a hair more timing in Neptune. The factory camshaft is definitely holding this back a lot.
As for the ported intake, zero loss of torque anywhere, just makes power at all points. It feels awesome and is super quick due to powerband/gearing. Grab just about any gear and it keeps accelerating. Ran an 08 Civic So with intake/race header/exhast/hondata the other night, did a couple of runs. At low speeds, my car pulls about a half car out, above 75mph or so, the Civic got back even and started to pull away, eventually getting about a car and a half length out to the top of 4th, which is about 100mph. From a dig, it was about the same, maybe me getting a little extra length.
Already sent Derek at DDTech an email about a camshaft.Comment

Snapped up these 17x7 Axis Touring Cups for $160 with two sets of tires from a buddy yesterday. Will be going on the car for summer while I save up some dough for super fancy tires for the Racing Harts, like R888's or another R compound.Comment

Also some Racing Hart test fit eye candy. Done without spacer to see where I may potential have clearance issues.

The wheels will look great once you get them on the car. Have you heard anything back from DDTech yet, on the camshaft for the F23Ax? I'm really interested in any info you happen to get back. I'm still debating on building either a true F23A1 that I have or doing the hybrid F23 bottom end with the F22 head and valve train. Since I have both engines, just I already have 2 cams for the F22, but the F23 just seems so much more beastly across the entire rpm band.Comment

Not yet, which is fine with me. Trying to see how I can make it to CAM since I got enough vacation time off.Comment

Oil changed, P2A5 reinstalled, installed poly filled trans and rear mount, put some 225/45/17 Sumitomos on the Axis Touring cups I picked up, now the ol' dirtbag is ready for the trip to CAM! See you guys there!Comment

Wheels lookin real nice! What are those if you don't mind me asking?Comment
