Check out MPD for hoods, I have one and Crazyguy03 has one as well and they are great for heat release and Cold Air (RAM AIR). Here's the link.... http://www.mpd1.com

Anyone know the actual flow rate on siemens 60lb injectors? I have seen anywhere 60-65, that is big difference. I used 62 in my tune...

@  jwguinn : (18 September 2017 - 03:31 PM)

Anyone know the part number or where to get a replacement for the short very curved vacuum line that connects to the throttle body mine is split where it connects...?

@  EnderDRM : (13 September 2017 - 12:04 AM)

So the headers and 3" exhaust is on. Sounds pretty good.

I'm looking for regal "GSX" emblems. Anyone have any for sale? I am looking for the OEM SLP GSX chrome emblems. Thanks

@  EnderDRM : (30 August 2017 - 09:27 PM)

Hi all, I thought I would get the plugs replaced while the headers are being installed. Recomendations for plugs?

Speedy daddy is the default cheap. I have been running pacesetters for 10 years and with the exception of one issue have had no problems.

@  scottydoggs98 : (22 August 2017 - 02:02 AM)

So a while back me and my buddy found a grand prix gtx in the junkyard and grabbed the supercharger,180* thermostat and the rocker arms. It must have been a stage 3 gtx because it had the 3.5 Magnuson pulley on it and other things. But my main question is if can't seem to find any markings indicating the rocker arms are 1.8s. Also if it would be ok to install them onto my regal not knowing the order they came off the gTX grand prix I have the rocker arms,pedestals, and the pushrods.

Only zzp made modified stock rockers. The rest of them are billet aluminum.
What makes you think these are 1.8s?

Unless the GTX was different

Unfortunately I never found a GTX brochure to be 100% sure

BUT

The should be made by SLP and look like those In the GSX brochure if the GTX you found has em

Ive seen them they look identical to stock ones yet the gtx we took them off of was a stage 3 car we think because it had the 3.5 magnuson pulley which only came on stage 3 cars. The car had been debaged but had the slp hood and everything.

1.8's only came on the Buick LSX and there was no "LSX" for the Grand Prix, they had the SE and GP  with the 3.1 engine but I don't see where 1.8's were intro'd to these on the literature.  

The GTX stands for Gran Tourismo Experimental where the GSX stands for Grand Sport Extreme and LSX stands for Luxury Sport Extreme. 

 

Here's what you got for the Pontiack GTX...  you may have to click on them to enlarge so as to read.  And check this out, no mention of 1.8's.... http://artandspeed.c...-Grand-Prix-GTX

More than likely a misprint or the cut from the LSX portion and pasted it in the GSX portion by mistake or by design.... poor graphic artist.  I would only trust the manufacturer's brochure, not some cut and paste job from a franchisee making a facsimile.
