Re: Quickshifts 91 Firebird LSX Swap journal
Small update because I was bored. Got the engine all cleaned up and brushed on a coat of black paint. Ordered an F-body oil pan that should be here friday. I will have to have a fitting welded onto it though before it goes on my engine for the turbo drain line. Also got my valve spring install tool so should be putting the Z06 cam and valve springs in tomorrow maybe?? Pulled off a valve cover just to see what I was working with and am extremely happy with how clean the engine is internally. Looks like someone did their oil changes!

Re: Quickshifts 91 Firebird LSX Swap journal
Got around to installing the ZO6 camshaft and valvesprings. Went pretty smoothly...I had bought this tool off a guy on ebay that allows you to change valve springs without pulling the heads off. It comes with an air hose which you thread into where the spark plug goes to fill the cylinder. This way when you remove the old springs, the valves will not fall into your engine. Also purchased the much needed front accessories (power steering pump and alternator) so should have that all buttoned up as well as the F-body pan on next update. Then the engine is ready to drop into the car!

Looks good. I wanna see the race between you and your bros when both cars are done, that would be epic!
Re: Quickshifts 91 Firebird LSX Swap journal
Billet rails (actually extrusions not billet) make a boring LS1 intake look sooo awesome

Ive never had any issue with valves dropping. Just bring each piston close to TDC. The valves will fall down some, but never out of reach with the spring compressed

Re: Quickshifts 91 Firebird LSX Swap journal
Hey guys. Not a lot of huge updates but just wanted to let you all know I'm still alive and I'm not ditching the project lol. It's just been a long few weeks between losing power for 6 days and yard clean up (noreaster in october? Thanks new england...). Anyways, I've been hustling to get the drivetrain in the car. Just ordered the LS1 bellhousing and will be ordering the swap mounts this week. All I will need to get is the clutch when I decide which one I want to go with, and then there should be some major progress. I notched out the K-member over the weekend to clearance the LS1 oil pan. Still need to weld it up in the next day or two. Also have been looking for a set of wheels... I came upon some M3 wheels that a co-worker of mine was selling and knowing that they have the same lug pattern, he let me take them home to test fit. I was a little leary at first, but I kind of like them! They are staggered, 18x8 front and 18x9 rear. It's tough to really gauge how they will look since the car is up on jackstands and not at normal level, but I will get some pics up as soon as the car is back on the ground. Let me know what you guys think, and I promise there will be more updates soon!

I love the look of those BMW wheels. I think Twin Turbo put some 5 spoke M6 wheels on one of his Camaros... looks badass!

Thanks man. You gotta stop by sometime soon! These wheels look much better in person. The pics really don't do justice to how nice the contrast is between the gunmetal wheels and the gloss black paint!

Re: Quickshifts 91 Firebird LSX Swap journal
Here's the pics of the K-member all boxed up. Keep in mind this was essentially the first time I've ever welded besides a couple small practice beads, so may not be the prettiest. Overall it came out good though. I ordered the swap mounts and clamshell bushings from Spohn this weekend as well (gotta love sales!), so the engine will possibly be going in next weekend if I'm not too busy from all this X-mas stuff. Stay tuned...

Got some goodies today! Thanks to Spohn for super fast shipping and great customer service. Still on target for this weekend to have the engine in. Won't be able to get the trans bolted up untill I find a clutch though.

Re: Quickshifts 91 Firebird LSX Swap journal
Wish I had some big news but unfortunately this weekend was a total wash. I needed to get the LS1 oil pan on the engine before I dropped it in, so I left it at the local machine shop to weld the aluminum drain bung on for the turbo. They called me and said it was all set. When I went to pick it up, they welded it with the threaded part into the oil pan! WTF? No logic at all behind this, and I was pretty dumbfounded. They are now supposed to get me a new -10 fitting and weld it on the correct way for monday. Probably won't get time to drop the engine in untill next weekend though.

Re: Quickshifts 91 Firebird LSX Swap journal
Wow I don't know why the shop would put the fittings inside the pan. I guess it gives you time for more parts shopping lol.
BTW, did those BMW fit without any adapters/spacers? And what are the sizes?

Good news! Got the pan back today. Everything looks good. Just need to slap it on and the engine goes in. Also picked up this sweet little EGR blockoff plate with the LSX logo. Figured it would dress up the manifold nicely.

Got the swap mounts in...Getting closer!! And I know that the K-member is not painted under where the old SBC mounts were, but I plan to go with a tubular K-member next winter anyways so didn't bother touching it up.

Re: Quickshifts 91 Firebird LSX Swap journal
The GM pattern is NOT the same at 5x120. 5x4.75=120.65. it is close enough to work, but this can stress the studs and cause them to fatigue over time and break.

Thanks for the info. Never heard that factoid before. I do know of dozens of people that use BMW wheels on their GM vehicles with ZERO error though, so I'll take the chance.

Re: Quickshifts 91 Firebird LSX Swap journal
Engine is in!!! I've been hustling over the past few days to get all the little odds and ends done. Drilled out, blasted & painted the mount clamshells and installed the poly bushings. Cleaned and installed the LS1 windage and pickup as well. Also had to drill and tap the block for the last alternator bolt since the truck iron blocks don't have it already done. Came out flawlessly though. It's nice to finally see some major progress and things starting to take shape. Should be ordering my monster S3 clutch and slave cylinder this week so I can bolt the trans in next.

Re: Quickshifts 91 Firebird LSX Swap journal
Thanks guys! Messed around with it a little more tonite. Wanted to see how all the turbo piping was going to fit so I mocked it up to check clearances. My bro took off his turbo hotside to be modified so I borrowed it to see how it would look/fit with my setup. I think I'm going to run a turbo blanket because I don't want to burn the paint off of my fender well, but otherwise there should be plenty of clearance.

Looking good! I like your turbo location, seems to fit in there real clean. What are the plans for the downpipe? You turbo guys are making me envious...
That LSX plate on the manifold really dressd it up, looks great. Nice work!

Re: Quickshifts 91 Firebird LSX Swap journal
Small update. Got a throttle body! Long story short, I ordered a FAST 78mm. They ended up sending me a FAST 90mm. The 90 doesn't bolt to the stock intake, so I needed to order an adapter. After some thinking, I figured if I upgrade to a 90mm manifold down the road, this TB will be perfect, which is why I kept it. Also ordered a Monster S3 clutch kit. Not sure if it will be here before x-mas, but when it comes I will throw up some pics. The rest of the drivetrain should be going in within the coming weeks.

Re: Quickshifts 91 Firebird LSX Swap journal
So the rear end is at the shop having the gears installed, and as soon as its back (sometime this week) it will be going back in. Now I made another purchase unrelated to my bird. Was cruising through the next town over a couple days ago and something caught my eye...2006 GTO. A car I've always wanted to own, just never run into the right opportunity. It was traded in on a new Hyundai just a couple days before. I think i was the first one to test drive it, and ended up taking it home the next day. I'm a sucker for test drives

Re: Quickshifts 91 Firebird LSX Swap journal
I've always been a sucker for the 05-06 GTOs, the 04s with the single exhaust and no hood scoops just didn't cut it for me. You're probably gunna fall in love with the LS2. They're great looking cars and yours looks super clean. I almost bought and 06 silver GTO last year, wasn't stick like yours, but still such a clean car.
Anyways, nice score on a great looking GTO!

Haha...yea about that. Me and my bro made a deal for this winter that any time it snows he will take me to work (which hopefully won't be a lot). Then by next winter I should have some other little beater to get me around.

Re: Quickshifts 91 Firebird LSX Swap journal
Here's where I'm at now. Got my clutch, and now just waiting for the slave cylinder and i can throw the transmission back in. Rear end is still at the shop so hopefully I will get that back soon. I'm going to be pulling the gas tank back out because I've decided to go with a sumped tank from Nasty Performance. I only want to have to do this fuel system once, so I'm going all out the first time. Should have some more progress soon.

Re: Quickshifts 91 Firebird LSX Swap journal
Thanks for all the comments guys, and I'm loving the GTO. There's nothing I want more though than to get this car on the road! Got the clutch/flywheel and the bellhousing all bolted up, then ran out of heat in the garage and that's as far as I got lol. It was a frigid weekend here. I ditched the BMW wheels for something I thought would look/perform much better also. It's a set of oem C5 Z06 wheels. 17x9.5 front and 18x10.5 rear. These things are super light and look great. Once I refill the propane heater I will be getting the transmission in there.

Re: Quickshifts 91 Firebird LSX Swap journal
Hey guys...been a little while. Got the transmission in! One of the bolts was stripped for the slave cylinder, so I tapped it with an M7. Come to find out, M7 is one of the harder to find bolts! Had to look at 3 different local sources before I found a bolt at a small local hardware store, but other than that minor problem everything went well. Now just waiting for the rear to go in. Can't wait to see it back on the ground!
