Thread: Worthwhile Mods

In case you didn't know the L36 is the N/A 3800 motor.

PCM's are designed to be put on modded cars IMO and putting one on a stock car that is pre-tuned is pointless...sure, you'll see a difference, but not as much as if you had all of the mods that it requires. I'd Do Exhaust and intake, get your plugs and t-stat...then get her tuned...and if you ever top swap then get a HP Tuner and tune the PCM you have...if it unlocked.

If you replaced it and didn't ask it is most likely a stock 195*. Get a 180* when you put the PCM in.

PVC intake out performs just about anything you can think of and my PCM is just sitting there without even being tied down. its a whole new world, listen to us who actually have a lot of experience with these cars.

replacing the DP does not warrent replacing anything else.

Stainless Steel downpipes, they sure don't rust. Tell him that one. Tell him most of the 3800 community LOL's at him when he says you'll have to replace the entire exhaust...NO...fail...the downpipe is a DIRECT BOLT IN REPLACEMENT. It bolts up to your stock catback all you need is new gaskets...that's it. Also go and show him my thread that you've read "Safely Modding Your 3800 Powered Car". That might give him an idea about what you've got on your hadns and what you can do to it. I can say that the TDC Intake is a very good product...I am just one to tell you making one does just as good. BTW...your Dad sounds like my uncle..."oh you got a nice car now with ****ing with it...its not made to go fast" LOL Whatever I tell him.

haha yeah your uncle does sound a hell of alot like my dad lol. Thanks for the idea blue, I'll tell him exactly what it does and of course show him that thread you wrote up. Great ideas! Maybe he will believe me when I tell him that these people know their ****.

Edit: I'm just editing cause I don't want to double post. Anyway, I won't need a pcm tune for just a dp will I? I'm thinking of doing: plog, dp/ubend delete, fwi, and then once thats all done I'll get a custom pcm from overkill probably. Does that sound good or should I get the pcm earlier in the process? If I'm thinking right then anything dealing with the exhaust should NOT require a pcm tune. Is that right?

Those PCM's are tuned FOR bolt-ons...get a 180* T-Stat and a set of Autolite 606 spark plugs/new wires when you install it too just for safe measure. And no...you don't need a tune for exhaust and intake work IMO.

Well...it is a great mod regaurdless even if he does eventually top swap...IMO I'd still get one. You can sell them for nearly what they go for because N/A guys try to get them used all the time IIRC. They sure ain't a waste of money for a N/A car...I've ridden in one with it and a GT2 cam and exhaust mods and that thing felt pretty strong before and even MORE with the HV3...in short...GET IT. Then when you top swap...if you ever do. SELL IT.

If your dad replaced it im sure its the 195, they're only about $10 anyway so I'd just go pick up a 180, just so you know though the t-stat won't make any difference without the tune. I'm almost done putting the parts together for my swap now, can't wait.
THANK YOU for listening to everyone on here btw, so many new people come on here asking for advice and tell us we're all idiots after we give it to them. These people have honestly saved me thousands that would've otherwise been given to a shop for unneeded repairs
Custum FWI all the way as well, that was my first mod and it works/sound great. I didn't even so much as zip tie the pcm its just sitting there as of now as are almost everyone's here that has an intake. But if you're worried about it ZZP has a pcm tray you can pick up for around $40.

It says on the bottom of the T-Stat the temp of it.

If I end up getting anything I'll give wd40 a try but hopefully nothins gonna be breaking. I haven't heard of any other problems from people so hopefully it wont be a big deal.

Use PB Blaster starting a few days before you do the swap...and spray the crap out of the bolts...you might not break them then.

I'm not really sure when I'll get around to topswapping so this would be good for me, and I'm glad to know that I can probably sell it and get my money back out of it. Thanks blue. Oh and let me get this straight. The hv3 insert is an intake mod right? Therefore I wouldn't need a tune or anything. But would it be a bad idea to run this without a different air intake? I don't see anything saying it would be bad, but for some reason it just doesn't seem right haha.

Yes, it slides into the bottom portion of the Upper Intake Manifold (the big black plastic thing ) You don't need a tune for it...but it won't hurt anything to put it in with no mods, you'll just see more gains with a intake and exhaust work so it can work to it's fullest potential...follow?

Cool, I'm glad to know that there wont be any problem with the pcm moving around. I'm half tempted to just go and make a fwi on my own. Its not like there's anything hard to it. The hardest part will probably be cutting the pvc lol.

Thanks again blue, can't explain how much of a help you are haha. You think one can of pb blaster will be enough haha. Yeah I understand about the hv3 though, I might try to go with the exhaust work first just to get it out of the way and then get the hv3 later on. With the hv3 though, whats the option for "add L36 upper intake"? Would I need that? Thanks.

But if I do happen to break a bolt, whats the downside to that? Is it gonna be a b**ch to replace? Thanks guys.
