I am going to a ATI 10% overdrive and stock upper, with a choppier stage 1 cam, or keeping the LS9 cam and going with a 18% lower and stock upper. I'm debating on going flex fuel sensor and e54. Either way, I'll be staying returnees but opting for Proxes fuel system with DW400.

LS3goatee As everyone knows I absolutely hated my 3" Magnaflow cat-back setup, so I finally deleted the mufflers. I replaced them with 3" Carven r-series mufflers. I will upload a vid with some exhaust clips later today - I have that distinct idle from a LS9 cam again now, it isn't drowned out and quiet like the Magnaflow. Exhaust RUMBLES, and the butt dyno feels something extra. Very pleased, it is just as loud as the Borla ATAKs, but with a deeper rumble.

LS3goatee I pulled the trigger on a Nick Williams 92mm throttle body. My previous 92mm Warr Performance TB made a LOUD screeching/whistling sound for the first 20-30 seconds of a cold start. RPMS would dart up to around 1100 and it would "cruise control" coming to a stop. It was evident the moment I looked at the Nick Williams that it featured a bigger IAC opening, as well as a small pinhole in the TB blade. The moment I fired the engine up, it had ZERO screech/whistle, and the IAC counts quickly dropped to ~49 counts as the car warmed up. Coming to a stop there were no more cruising, and the idle issues (random surges) were solved - even the VCM scanner showed a more stable idle. I was shocked it made such a drastic difference, but I see why people avoid the "china" TBs. And yes, I adjusted the Warr Performance TB almost weekly and I could never get it right, while the NW throttle body took ZERO ADJUSTMENTS.

Nick Williams on the left, Warr Performance on the right:

Some minor upgrades

Took her apart for a few minor mods:



DMS billet manifold. Upgraded this to tidy the engine bay, but peeking inside the OEM manifold, I noticed it is has jagged portions on the inside that could negatively affect flow.



12AN ORB fittings



12AN SS braided hose w/nylon cover

I agree. They were only 26 bucks each, support up to 150lbs, and I figured since I'm not removing the bumper frequently, the push-button mechanism will be free from failure for a long time. Removing 4 screws (2 on top, 2 on the sides) and pushing 2 buttons gets my bumper off! The SAP lower and splitter make the bumper much stiffer/sturdier, so it goes right on and off without issue - I hope that makes sense.

3" Magnaflow. Pure garbage, so many people like it but I miss my 2.5" Borla (vids of it on my channel), but wanted a 3" system for the blower. I'm cutting the mufflers out and replacing them with Borlas again.

Only credit I give to Magnaflow is it is loud WOT, and I get a lot of compliments from people who spot me on the road.

I am catless LTs btw. Infuriating how quiet it is.

I have, I do want some 15x10 welds in the rear. Traction is an issue. I bought some Racestars but them shits said made in China so I sold them. Welds are made here in the US and look much better anyway, they'll probably be my next mod.

LS3goatee I posted these in the FB page since I get so many questions about my intake. Colt, understandably, has left a bad taste in a few folks mouths... But my IATs are phenomenal. With the new HX, I got IATs (read from the lid / IAT2) within 1* of ambient with highway cruising, and 3-5* consistently with spirited highway driving (shoots up and right down WOT), and 5-7* in moderate traffic in the city hitting every light (Bell rd). It is important to note that due to the law of thermodynamics, it is not possible to be below ambient air temps without something like an interchiller, which is overkill for my setup of just 7lbs where I will stay. It gets 110+ here, and on days like that it'll sit in the garage lol

Mid day here. First time driving in two weeks so I drove aggressively on the backroads and pulled into an empty lot and idled for about 10min taking photos. Short highway drive and I snapped this photo.



This was later that evening. Peaceful cruise. Temps switched between 1-3* of ambient at 70mph.

That is fair, I never realized how ugly my original front end was until the facelift. I think a Mavman spoiler will balance the front and rear. Maybe even a diffuser.

LS3goatee Completely changed the look of the car (ignore the smudge on the hood)!

LS3goatee Before I could mount my bumper, I had to either replace the bumper clips, or add a new means of attaching it. I added a Quik-Latch to it! Measured once, cut about 3-4x!!!



Kinda silly, but about 12 hours into my 48 hour cure period for the ceramic coat, I drilled into my bumper for the quick latch. I should've done this first! Had to blow dust and shavings off of the bumper as well as use a microfiber to softly whisk away debris. Stepped drill bit made quick work, and a dremel to flatten the backside so the nut would tightly secure the latch.



You can see the Quik-Latch here. Bumper is secure! Driver side is a bit low, but I'll leave it alone for now.

LS3goatee Picked my bumper up yesterday! My guy Bobby always gets it done. I did pick it up early in an attempt to go to a car show, but it ended up not working out. The 'unique' portion I alluded to in earlier posts was a yellow accent on the "D" of the lower grill - but last minute I canceled that idea thinking I'd have to change the emblems yellow, although it'd match the brembos perfectly. I don't like SAP upper grills, they look grand-prix-ish to me, the stock grills are the best in my opinion!



I ceramic coated it myself this morning and it turned out great. I ended up tipping the bottle over on accident and spilling it everywhere smh ($70 down the drain) and have less than 1/4 left. That bottle was supposed to last years, as I only used it on the hood to protect the carbon fiber, as well as the front bumper.



I took a vote on my instagram, as I usually do, and the people chose for me to go aluminum instead of the sleeper black heat exchanger. Aluminum BARELY won. To my surprise, the HX was a massive upgrade in size and capacity (I ordered blind, as I usually do). I did have to remove the lower air dam, but with all the cooling upgrades I have I doubt I'll miss it. For the first 3-4 months I owned my GTO, it didn't have an air dam.



Another benefit is not having a hose run along the front of the HX. Less hose, less bends.

Thank you! And I just figured with the heavy amount of messages I get on FB and IG (over 75 message requests on FB, it is cumbersome) that this thread would be lively, but its all good.. I'll keep posting

Vemon I'm inspired for sure. Just finished my LS3 NA build in my 04 and this is the next step. I'm hesitant to go cutting on the stock hood, looks like you went with the mavman cowl, how do you like it? Also, what air intake set up is that going over the radiator? Love that you did all this yourself, you and I are the same. I'm weighing the option of adding LSA to my current setup or starting a new LS build on something like a Porsche 944.

LS3goatee All issues fixed before priming.



Primed and ready for paint! Should get it back tonight or tomorrow.

LS3goatee S/O to Bobby, my body guy over the last few years. Best part about using him is he sends tons of photos along the way. Dropped my headlights off as they were super beat, and the previous owner cleared over them and it was starting to haze. My passenger headlight was dry rotted so bad, when I touched the top it crumbled and caved in - Bobby was able to repair them and even reattach the top tab that was broken. Here is a pic of the clear. Can't wait to see the finished product.



A little bumper update...
So, the previous owner drilled the bumper into the clips, bondo'd over the holes, then painted the bumper. I found this out when I had to remove it the first time, you can see the holes below - I ended up throwing some touch up paint to attempt to hide it for the last few months.



SAP lower epoxied and seam sealer added. Holes in the bumper filled. Paint soon after a bit more prep and I can't wait for it to be done! I do miss driving my GTO lol got a small but unique thing coming that I'm probably over-hyping, but it'll help me stand out a ton since the sap lower isn't exactly unique itself. Carbon fiber splitter will be a visual upgrade over my previous splitter





Here is the carbon fiber splitter. I was disappointed with the quality, the weave isn't even as you can see, but it still looks dope.

Thank you. It is done for the most part. I'm trying to keep it stock pulley but I occasionally get the itch for a smaller upper (just for a louder whine). Injectors at 66% duty cycle, and IATs are great, so I do have some room to grow. Body wise I'm doing some cleaning up, pictures hide a lot of deficiencies with my paint, but with the front bumper getting overhauled that solves 75% of those issues.
