262's 85 Fiero SE LX9 F23 swap thread lots of pics

When I look up that part # I get a zr1 map sensor which is a 3-bar.

I know my 97 pcm has a limit which restricts the MAP to no more then 2.5 or 3.5 bar. I am not certain on the limit amount, but i do know there is a set maximum number of bars we can run w/ the stock PCMs.

I wouldn't hit the max allowed, might trigger limp home mode or simply limit fuel to the max pressure, going leaner as boost climbs past the limit.

I would check myself but I am on my linux bt4 laptop atm.

oops! that's right, I forgot, I knew it was one or the other...


I also picked up a second LX9 yesterday, I got a good deal, and will be able to get things moving a little quicker this way.

I put "LS7" lifter springs in my stock lifters to hopefully improve the high rpm valve events, and what a bitch it was!



Right side is stock, left is the LS7



24 lifters pistons.



check ball and check ball spring retainer left side has the retainer removed.



Check ball springs are also tighter than stock.



I would just use the whole "LS7" lifter, but they are taller (this is a pic of just the piston, stock on the right, "LS7" on left.



lifter piston with the main spring installed on the check ball spring retainer



then the lifter body slides over the piston and spring



and now we have the whole assembly upside down.



piston in the body



this thin disc then gets placed in the piston.



disc installed



then the pushrod socket.



installed



that is the piston retainer, it fits into a groove cut into the top of the main body.



Push the piston down in there, slide in the retainer, and then you are done!



should hopefully be good to 8000 RPMS

You are not kidding! I disassembled mine, inspected, cleaned, reassembled....all while keeping everything in the same place, same line up. It was a long tedious cleaning but worth it imho.

I started making my a2w intercooler mounts, still needs a couple of gussets, and the other side(not pictured) re-done (measure twice cut once!)

[ericjon262]

Intercooler mount is almost done, just needs a couple of strait legs trimmed down, cleanup, and paint.

Please excuse the crappy pictures, I'll see about getting better ones tomorrow.

[ericjon262]

more pics, I went out and finished the welding, trimming, and bracing.

[ericjon262]

well, I thought I was going to get more done today, but that's all. I am going to try to mount my intercooler heat exchanger tomorrow, and start plumbing it in place.

[ericjon262]

need to modify the bracket a little, the corner down by the frame is about 1/2" from the crossmember.



I'll cut is at 45* across the corner and weld a angled corner to add about an inch of clearance.

didn't get around to the heat exchanger, ended up being pretty busy getting a couple of smaller projects wrapped up...

[pocket-rocket]

A friend of mine made a little "machine" for taking lifters apart. It makes it a pretty easy operation. It's made of wood and a door lock like what you would use on a shed door as a plunger to push the pushrod socket in to remove the retaining clip.

started the heat exchange mount today, I'm debating on whether or not to run fans on the core.





The "H" frame will be welded to the a/c condenser support, and the heat exchanger will bolt to the frame.

[ericjon262]

Finally got my tank in!

[ericjon262]

don't have much to report other than that I mounted my heat exchanger to the car. hopefully later this week I can get the plumbing handled...

[ericjon262]

bad news... my truck is starting to develop a tick/knock... I'm hoping beyond hope that it goes away with an oil change, but I'm not holding my breath either (250K+ miles...) hopefully I don't have to rebuild/replace the engine... we'll see...
