'25 Integra ASpec CVT Build

[slowcountry]

Here are some stance pics - thought they give a good view on stock wheels/tires since I have 20mm on the front and none on the rear. Rear spacers go in soon!

Ah forgot - got this in yesterday as well

Very dope build! Any plans to ever get it on a dyno?

Local shop is getting one in a few weeks. It's booked up already, but I think I'll be checking it out towards Q3 2026!

Much UWU! Plz post results when it’s done?

Here is is with the rear 20mm spacers added

This is an impressive build for a CVT. Really going to be looking for how the CVT holds and how your numbers are once you hit a dyno.

I forgot we have a dragy pro at work - I'll see if we can take it for a spin soon!

Feeling paranoid because I forgot to double check the intercooler outlet charge pipe clamp while I had the bumper off for the intake snorkel install...

I played with the layout on the ktuner v2 and realized I was underutilizing that device... I've had it displaying just 3 gauges all this time... none of the data reads. So I went on a ~15 minute spirited ride with all of the data on.

First pull was in normal mode 30 - 70 and peaked with 21 MAP PSI and 21 TC TARGET PSI. Second on the way back was in S drive & Sport mode on a long ramp with slight decline... and I forgot to look down at the gauge. I logged it - will try to see if I can take a look tomorrow. Really need to compare this drive to a similar drive in manual mode.. Drive finished with ECT at 197 and Trans Temp at 185, and k cont 0.49.

So everything seems to be working correctly. That said, I still want to take that bumper off to be sure

Side bar - picked up a Carismo wheel & will try to get that installed this weekend.

Carismo signature perforated leather wheel with the matte CF trim and CF magnetic paddle shifters installed -

I got the steering wheel used here on the forums & got the trim from carismo, but saved on white-label shifters. Pretty simple install, just takes patience with fitting the trim back together. The paddle shifter wiring harnesses have to be routed up by the ribbon harness on top for it to fit back together.

I also got ZL1 Add-ons rock guards to protect the paint a bit now that the wheels are offset. ZL1 doesnt make them for the integra/civic si so I ordered the civic ones expecting to drill my own holes. Think they turned out pretty great - can share basic measurements for the holes if interested. I sent the details to ZL1, maybe they'll offer them eventually.

Last - have been trying to figure out a squeak that sounded like it was coming from the rear sway bar bushings. I loosened and retorqued those under load while adding a little lubricant for the bushing.

While I was there I checked the torque on the rear subframe chassis bolts and found them around 60 ft-lb. Not sure if it was from the stiffer sway bar or just chassis settling, but torqued those down to 69ft-lb. Might be worth checking your rear subframe chassis bolts!

Just gotta say - out of all of the installs, the rear sway bar has been the only real nuisance. From brackets coming loose, to end link bolts snapping, to grease wearing out.. I uninstalled and reinstalled it last night, first 2 drives I'm on cloud 9.. 3rd drive it sounds like the bracket is loose again and one of the endlinks seems clunky.

Some of this is user error, but dang man Lol

Was able to check the intercooler outlet and confirmed no boost leak. Will have to do some more max boost testing because I've only seen it hit 21psi flat so far. The tune on map 3 is supposed to be 25, but they may have limited it to 21 on the cvt.. perhaps.

While I had the bumper off I "pre" installed the ETL transmission cooler. This is made for the 10th gen civic so the mounting brackets don't quite work. Happy with how I got it mounted, though.

Routed the fluid houses into the engine bay, so once I'm ready to put in the sandwich plate it's good to go.

Also, had an amazon gift card so I went ahead and got the matte center console trim:

Installed CCF amd MLV on top of the dynamat in the spare wheel well. Have a lot more material so plan to do at least the doors and rear wheel wells.

And last, got the Suma mirrors in that I had ordered last November. Waaay more blind spot visibility on these and very simple install.

Next plans -(may do this in 1 go at the shop):
1. Due for oil change, add mishimoto drain plug
2. Transmission cooler sandwich plate install, drain and fill, and add the mishimoto drain plug
3. Wunderladen billet idler/tensioner pulley

Would like to get the WOTP x HPT cooling plate before summer as well.

Hey Dylan, if you haven’t installed one yet, I’d recommend getting a ground wire kit done (or having someone help with the install). It helps improve electrical flow throughout the car. I’m running one on my 2025 Acura Integra A-Spec Tech CVT, and while it’s not a huge change, it does make the car feel a bit smoother and more responsive overall.

This is amazing. I don’t have the guts to modify mine. Just a purist.

Haven't got the trans cooler hooked up yet, but have been working on some sound deadening on the doors. Just finished both the front & rear doors, then added a layer of MLV to the trunk.

Basic process for doors:

1. Remove door card, set aside
2. Carefully pull off vapor barrier (if you want to reuse it). Let it hang there.
3. Apply dynamat in as big pieces as possible on the interior metal of the door, and then also on the inward facing metal surfaces. I used about 1 sheet per door, extra pieces were used on the door card.
4. Apply Siless CCF over all of the dynamat.
5. Replace vapor barrier.
6. On the door card, I used the extra dynamat on the larger open areas, but I wasn't trying to hit total coverage. Then, applied the CCF pretty much all over the back of the door card. A good spot to hit with both is under where the widow & door locks control rests.
7. Used a speaker ring (sound skins) on the speaker. Not sure if the door card fit over it perfectly. Might be better to apply to the inside of the housing on the door card.
8. Replace door card

While doing that, got to thinking of which mods are my favorite outside of engine performance:

• Front tower strut
• Steering wheel & the magnetic paddle shifters
• Wide angle mirrors

Went to the shop for oil change and went ahead and had the ETL trans cooler sandwich plate installed. So glad its on there - will report back on how my trans temps have adjusted with it on.

Just hit 10k miles so did the trans fluid drain and fill as well while they were in there.

Pic of the trans cooler mounted is a few posts up, sandwich plate below

Before:

After:

New priority list:

1. Titanium head studs, cam plate
2. Cooling plate
3. PRL Turbo & tune revision

Also would like to add/finish:

• Justa335i's center console gauge cluster (need gauges, have oil filter sandwhich plate - will be doing oil temp and oil pressure).
• Wunderladen oil pan baffle, dip stick
• Wunderladen idler/tensioner pulley

Also, they repaved my road so spoon progressive lowering springs could be added back to the equation... Would pair with adjustable camber arms and roll center/bump steer correction kit.. Really need to consider if I should do the turbo or suspension first.
