I'm doing the same f body radiator mod. You may have to adjust the lower radiator line.

What would you say are the top 3 non-performance and performance related mods you made to your car? Post some pics if you have some.

OK, I’ll go first.
Well, the lines get blurred between performance and nonperformance.
I am more less talking about things that made “PESKY” assembly easy or some small things that will make a difference. Not talking about

Here is my criteria - Try NOT to list mods that we pretty much all know about and/or are easy. Example; Upgrading the ECM is “easy” and we all know about it.
I’ll take a stab at it. This is just my opinion and you can list an state yours.

Non performance ……..
Turbo bracket - This is a gem! I take no credit for this one and belief Buickpower to be the originator. This is an awesome mod and saved me 2-4 hours of fighting the ******* oil return tube!
Valley pan gasket cutout – This will allow the oil to drain into the block and “hopefully” reduce the oil sucked up through the PCV. Easy mod to assist in combating pesky oil problems.
Interior painting – This is a GREAT mod for any enthusiast who would drive the car for a while. A clean and well kept vehicle should have a higher market value

Performance
Dual fans – Pushing the air for a “OEM” engine bay look. Fans are from a Nissan and I now have the platform set to adapt any dual fan.
Exhaust system locating pins - Allows repeated precision alignments. No. I do not plan to take them on and off, but, the ports and headers are “without any doubt aligned”.
TB O-ring – I did not want to worry about gasket protrusions and possible leakage so I added an o-ring.
Okay, I'm stuck in the sticks of N.E. Texas. Can someone please send me a link, or the specifics on which year/parts I need to upgrade to the fbod radiator install? Thanks

The parts you will need is the radiator from a 87-92 camaro with the 5.7 v8. If you plan on adding electric fan you will need to cut your fan shroud down or just get a 86-87 turbo regal top radiator hold down plate...g body parts is a great place to source one or kirbans performance

The wiring harness for the fans can be sourced from caspers electronics

I saw a couple of people mention the 3in downpipe as a good HA mod. I checked Gbodyparts and found nothing. Also checked buickgn.com and saw a few downpipes which appear to be only for use with Aftermarket Headers. Interesting, I don't think Headers were mentioned in this thread. Anyways, where do we get downpipes from these days? AND... does anyone have a verified dyno report to indicate how much HP the downpipe added?

Believe it helps with spool up and maxing out the turbo but I'm no

Brian @ gbodyparts was the only one to carry them. I see they are no longer listed on his site. Might give them a call to see of they have any left. Year's back he bought my mease downpipe and made a bunch. He Might have sold them all and pulled them from his site as the market isn't there for them anymore. As for power, if you want to make any real power you need one. How much it helps depends on your mods

Just have a quick sec so no heavy thought into this right now, but let me be the first to add the one thing that comes to my mind whenever someone says the phrase "best mod": Alcohol Injection
Its just by far the single most beneficial thing Ive ever done to the car. Ive seen plenty of intercooled car owners state the same thing.

Good thread by the way. Dont want to call you a newbie Jerryl :tongue: but nice to notice someone new in the last 1+ years that seems to really be contributing to the community :cool:
Thanks for the info everyone, I just bought an 84 T top with the tan/charcoal interior w/ lier seigel seats. First GN!! Yeah!

Great tip thanks, I had a knee-jerk reaction and bought the Cold-Case GN Radiator from gbodyP’s. It was specific to the GN so I assumed it was the way to go, the fans/shroud/wires as a kit as well. Lol.. now after a bit of reading some are saying to buy the different bits from all over the place. wires from Caspers, shroud from Hartline.. Is the kit at GbodyP’s that comes with the cold Case radiator missing something as far as quality or installation ease?
