In case you didn't know the L36 is the N/A 3800 motor.
So if I was going to plan on doing the upgrades that I've talked about (fwi, plog and dp's, maybe a topswap down the road) would it be ok to buy a pcm to install for a first mod? Actually the fwi would be my first mod, but I have read that a custom tune will make a huge difference, especially with a stock gt, so I was considering doing it before everything else.
The pcm's and stuff confuse me a little bit. For example, if I buy one now and put in other upgrades requiring a tune, would I need to buy another pcm? And with the custom tuners you can buy (like hptuners) do the credits limit how many times you can tune? Like do you have to buy credits after the 8 that come with it are used? Or can you just use it as many times as you want without buying the credits? Thanks again.
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.
Cool, thanks blue. I'm pretty sure I replaced my t-stat and awhile back but I want to get that plog and dp for sure and maybe one of those hv3 inserts.
If you replaced it and didn't ask it is most likely a stock 195*. Get a 180* when you put the PCM in.
alright I'm just gonna bring up this thread cause I don't feel like starting a new one. Anyway, I've been talking to my dad about helping me out if I mod my car cause he used to fix cars up back when he was a teenager (late 60's-early 70's). He knows alot so I know he would be a great resource to help me.
First I wanted to make a fwi but he's like I don't want you making something out of pvc and putting it in there. And like with the pcm he thinks its a bad idea to just zip tie it to the frame of the car. He says if you're gna do somethin do it right. I can understand that so I might just buy the tdc intake and get him to help me pay for it cause I'd rather just make one which would be cheaper. So I try talking to him about the d.p. and he's tellin me if I go messin with the exhaust I'll have to replace the whole exhaust cause stuff can get rusted and taking it apart can mess smthn up (I don't remember what his excuse was). But it seems like everything I ask him about he just says that its a bad idea and I shouldn't do it. That being said, I know my dad has alot of knowledge about cars but I know you guys do to haha. And I'm gonna have to believe you guys when almost everyone will recommend the same mods.
I'm asking if this is really the case with the dp and rust or w/e, and basically if anyone has some comments to help persuade him to give me some help haha. I feel like a d-bag asking stuff like this haha but I'm really interested in modding my car but I just need that little bit of help/assurance that I'm gonna be doing it right and not screw something up haha. Anyway, sorry for the long post, but thanks for any advice anyone has!
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.
Yeah I'm listening to you guys because everyone knows alot about cars here, but specifically grand prix's. Could you explain the downpipe installation process so maybe I can explain it better and understand how to install it better.
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.
and definately dont waste your money on a hv3 insert if u plan to topswap...because you have to get rid of that whole plastic intake manifold on top of the engine and thats where the insert goes...basically you cant use it if you are supercharged
oh and on the rust thing...my dad tells me the same thing too...that if i try to take the bolts out that they will snap because they are rusted on...yea but when i have access to a full shop and soak it in penetrating oil they came loose no prob...i suggest you soak the bolts in sone sort of penetrating oil...even WD-40 works ok...i like pb blaster and aerokroil though, they get the job done
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.Quote:

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.Quote:

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.Quote:

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 :p
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.Quote:

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.Quote:
