The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.

When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

As far as I can tell, this should give the answer:

With the alternator being a bit high and sitting out in front, there is some question.  I think I'll post a new topic with this pic since this question comes up all the time.

I decided to try to make my own alternator bracket for now. Metal is cheap and my boss seems to think my time is as well... rabbit

Alternator will go in essentially the same spot as the ICT product. Unfortunately I won't be able to tell anyone if it clears everything for a while.

Looks like i can make the TBSS injectors and rail work with a car intake. Wahoo for saving some $$$ rabbit

Well that was false. TBSS injectors do not work with a car intake. Now i'm shopping for injectors!

Alternator bracket should hopefully be finished tomorrow-ish.

Ordered a bunch of parts from Kent, thanks kent! Smile

Also got a turbo 5P trans coming from ebay rabbit

Well I got the alternator up there but now I don't have enough belt wrap on the crank. Should have seen that coming a mile away. There is no place to put a pulley/tensioner between the alt and the crank and no place between the power steering pump and the crank!

My only option is to move the power steering pump up. At which point I might as well put the alternator in the F-body location if i can...

Either way I gotta rid of my elephant trunk filler tube/reservoir for my steering pump. I wanted to just disconnect the filler tube but it looks like the filler tube and the reservoir are one piece of plastic. Shoot. I guess I'll take the plastic stuff off and do an external reservoir?

So I ordered a F-body reservoir and made a little bracket yesterday. Not sure I like the angle that the reservoir is on so I might make another bracket today or maybe mod this one. I know aftermarket brackets are only $30 but the steel to make this one was only $3.....

Seems like i'm the only one here but I'll ask anyways....

Anyone have problems seating LS2 fuel injectors? I asked over on LS1 tech but I'm not getting any feedback... I have a LS2 Manifold and LS2 injectors so the problem must lie in user error.

The orange O-ring is not making it into the injector channel. It's like either the channel is too small or the little black piece of plastic next to the orange o-ring is too large. I have silicone grease applied to the o-ring but the o-ring never ends up against a wall. I tried installing them into the fuel rail to help me push a little harder but still no dice. Super confused. scratch

I'm essentially copying the ICT billet accessory just paying for it in time rather than $$$ rabbit

As soon as my kit from Kent at TPC comes I can see what fits. There is some play with the alternator between being either closer to the passenger side or closer to the hood. From the photos I looked at online it looked like there was room in the engine compartment towards the passenger side, so I chose a location lower and more towards passenger side than the ICT kit.

We'll see if it paid off...

Well I got good news and bad news. The good news is I'm essentially finished with the accessory drive, the bad news is that if you were waiting to see if that ICT billet layout would work... i won't be able to tell you.

My problem with the ICT billet layout is that the tensioner uses a smooth pulley contacting the smooth part of the belt. Anyone who looks at the picture or link i posted can see that... unless you're like me and too impatient and rush into things. People talk about belts walking off ribbed tensioners with raised walls. I'm too paranoid to rely on that smooth pulley to hold the belt in line and there is no way to get a ribbed tensioner in there without doing something really creative.

Also, if i had known how easy it would be to copy a F-body like layout I would have done that to begin with. Alternator bolts into the right spot. Tensioner bolts into the right spot but the mounting surfaces need to be cut down to get the right depth. I already had my power steering bracket. All i had to do was make a bracket for the idler pulley.

Other than being easy, I know this layout will fit the 944 application which is part of the reason I did it.

All that remains is cutting down the mounting surface on the tensioner and it will be ready. Right now it sticks out too far. I measured 77.5" which is the stock 2005 GTO belt length (according to a thread on the internet, don't trust me). I ordered a belt and we'll see if it's the right length!

No, sorry if i wasn't clear.

I'm using all truck parts with the exception of a vette water pump. But everything except for the crank pulley required brackets/spacers to work. So the layout mimics a F-bdoy layout, but i'm using truck accessories with truck spacing. Does that make sense?

Hopefully I don't need that extra 1/2" or whatever it is of clearance you gain with the F-body accessories...

Haha holy cow I'm a wreck. If you haven't figured it out yet this project does not have my full attention.

I definitely could've kept the first iteration with the alternator hanging off the water pump and the power steering pump in the stock position. I thought this didn't have enough belt wrap but the stock TBSS engine has the exact same belt wrap on the crank. Laughing

Tried to put on my 77.5" belt and BOY is it tight. I don't understand how this tensioner works. It doesn't seem to move?? Makes putting this belt on extremely hard.

We'll see what happens over the weekend. Maybe i'll go back to my first set-up, maybe i'll buy a tensioner pulley that moves like this one [You must be registered and logged in to see this link.]

Still waiting on the swap parts to show up... rabbit

No trans or engine in the car, sold them to a nice fellow from Traverse City. Have chop's axles and the empi CV's in the car.

My only worry about my drive belt setup is radiator fan clearance. I'm hearing that alot of people are really tight on the f-body accessories and my truck accessories are gonna give me 3/4" less clearance....

Shopping for a turbo rad now...

Post  FrostedFlakeJake Sat Jan 02, 2016 9:46 am

What am I supposed to do for engine mounts? I have the TPC brackets but is there any suggested engine mount (polyurethane) to connect the brackets to the crossmember?

the Kooks longtubes and majority of parts from Eric showed up. Waiting on a few stragglers rabbit

TPC engine mounts should come with brackets that bolt to engine block and tubular mounts that have one side bolt to sub-frame and other end that has poly bushings that bolt to bracket.
Sounds like they could be with some of your "stragglers".

I got those! I didn't pay attention enough to realize there was a bushing where they connect to the part that bolts to the motor.

The two tubular parts that connect to the crossmember are two different lengths, do you remember if the longer one is driver or passenger side? My longer one is marked as driver side but there isn't enough clearance between the tubular piece and where the steering column connects for it to fit. The shorter mount fits there though. Wondering if they were mislabeled perhaps? Or is there some trick to getting the mount to fit? Question

The longer tubular mount is the drivers side.

I also used the Kooks headers on my most recent build. An attempt to install them after engine was in the bay failed. I had to install them before dropping in the engine.
Also, if using the quicktime BH you will have some clearance issues w/ the headers. At least i did. Nothing a grinder couldn't fix.

Thanks guys I figured it out. Installed just the crossmember with the spacers to see if my steering column needed to be modified and while I was there I test fitted the mounts and figured out I was having the tubular members pointed the wrong way Rolling Eyes

Doesn't look like to me that the steering column shaft will need to be lengthened! Taking the tail cone housing to my machine guy tomorrow. The vice on my old man's mill is just short of opening wide enough to hold it.
