Yeah, I saw those motors. Also cheaper ones, it's ok that they have alot of miles cause I don't care if the motor is junk I just want them for the intake and sensors.... for my 4.9L But what I need is a documented swap that worked out good and made a performance difference, and what the person had to do to make it all work...

I installed an Allante intake this summer. I had the car on the dyno before we broke the tranny. I had issues with the engine pulling all the way to 5500 rpm. The engine was running to rich. During the dyno testing the best that we got out of the engine was 194 Hp at the wheels with 295 Ft Pounds of torque. Unfortunaly on the way home I had a lost of oil pressure that killed the engine before I could get it shut down. I had to install a 4.5 (no 4.9's around right now). We took the 4.5 to the strip and my son pulled a 14 flat at 99.98 mph. Then the tranny broke. Still looking for a Getrag to replace the broken one. The car seemed to pull alot better and when I get it working again I hope to get better performance from it.

What sensors are needed for this swap..?? Has Rock done this swap also..??

I'd like to hear more about how your Getrag broke...

We were at the drags after the run, my son shifted to neutral and was coasting down. When he got to the turn out to return to the parking area he put the car back into 4th when he let the clutch out got grinding, clucking noises. Stopped the car was unable to select any gears. He got out to try and see what had happened. When he restarted the car he was able to select 1st. Drove back to the parking area trailing a line od tranny oil. There is no visible damage, we trailered thye car home. We checked the oil level at home and it is down a little bit and the car drives like nothing happened. I am looking for a replacement anyway as the tranny has over 155K on it, and I don't trust it. So if anyone has any ideas or a Getrag tranny they don't want let me know.

As far as what sensors are needed you need the 2 sensors that are on the Upper Intake. Air Temp, Mass Air Flow. The most critical part that you need is the fuel inlet line for the Allante Fuel Rail IT IS A VERY SPECIAL PIECE, and no one has one for sale cheap. I found a place in California that had one and they wanted $120.00 for it.So be sure and get both fuel line for your Allante Intake.

Figured out where the leak is coming from? Have you tried driving it since then? Does it work OK now, or can it only select 1st?
Every once in a great while, by transmission does something like that... It gets stuck in 4th and won't allow any other gears to be selected. That's an internal shift linkage problem that I haven't been able to figure out. After a bit of stirring the shifter it seems to fix itself, though.

I have pictures of the installed intake. I'll post some tomorrow. The install is straight forward, just unbolt the old intake and install the Allante intake. You will have to reroute the wiring for the Sensors and the TPS, IAC. Your fuel lines, and vacume assist line. I changed back to the throttle cable that was originally in my 88 Formula it is perfect for this intake.

For Will we have run it around the block. But now that you have mentioned it I will drive the car around a bit more to see it anything happens. Thanks for your input.

according to autozone's website, there is no MAF sensor for the allante, just a MAP sensor

if the tranny looks fine but was draining oil its probably got a crack somewhere..

Yeah, probably, but without futher examination, what can be said either way?

The intake can be changed while it is in the car. However there is a fair amount of wiring and piping that needs to be moved to different locations. From my experience I would recommend that the cradle be removed from the car it would make all the changes so much easier. I tried both the 4.9 and the Allante injectors, we saw no real difference on the dyno the engine was still running rich. I hope to continue tuning this winter (If I can find a new 4.9 and a getrag tranny)

Hi I got the 4.9 with the Allante intake and it works great the only thing I found after all my hard work is it won't start if it has been turned off for about 10 minutes it will start but the starter will have to turn over for a while not sure why. I turn the key on to get fuel pump working first and it works alot better but I don't think this is a big problem just one I have not learnd how to fix it yet. Be glad to help up if I can, however I only know by doing bubbajoe helped a lot and I'm useing Ed Parks wiring harness wiht 4 speed caddy trans.
Hope this will help I love mine but would love to solve this problem with the starting thing if I do let it set all night and then just turn the key over it will start right up but if I let it set for about 10-20 minutes well I got to first let the fuel pump come on and turn off then trun over the engine. I did change the air inlet to the stock Fiero air cleaner I should take a picture of that it the right thing to do.

Hmmm... Isn't a 4.9 just a stroked 4.5? If so, would it be less of a pain, in some ways, to just yank the crank, rods and pistons out and replace with the 4.9 set and boom - instant 4.9 with Allante intake? Yeah yeah, I know...get a proper rebuild done...

Or you could just put the Allante intake on a 4.9 and save a LOT of trouble...
I guess what I mean is: if you haven't done the 4.9 swap, why not buy a Allante motor and tear it down and freshen it up into a 4.9? Will Ed's kit work with an Allante motor?

Putting the Allante intake, and even Allante cylinder heads, if necessary, on a factory 4.9 short block is MUCH easier and MUCH cheaper than overhauling a 4.5 as a 4.9... The engines aren't that expensive... buying two of them to build one is really not unreasonable, especially once you start pricing overhaul parts...

To answer your question about the wiring harness Yes Ed's wiring harness works great you do have to leathin a few wires to get them to where they need to go.
