my LSx 87 IROC build
Re: my LSx 87 IROC build
How come your looking for firebird door panels? From what i can tell, your current ones look good. And i too would love to see how that diffuser was made. Adds something to the car from the rear.

Re: my LSx 87 IROC build
They're put on high end Performance cars and race cars to keep the rear end stable at high speeds. I'm not sure how much need there is for one on a daily driver like his car, but it looks awesome so who cares if it does anything beneficial?
Re: my LSx 87 IROC build
hey on an unrelated note, says you have an lsx, do you know if the high deck works well? i heard it doesnt work very well with camaros for the bbc engines just not sure about the lsx, its 9.75 instead of 9.25

my cousin west sanded the taillights.. mixed up some clear with a hint of black and sprayed them . i am debating weather i should paint the reverse light section red as well. i would love to do a sequential taillight kit..

Re: my LSx 87 IROC build
Is there any chance you could get some better photos of the diffuser, like with the sun shining on the rear of the car, or maybe throw some lights on the ground behind it so we can see it better? I've got an idea...

Cool I'd appreciate it. What did you make it out of in the first place anyways? And is it bolted together of welded together?

Re: my LSx 87 IROC build
i have a few questions. i have a leak on my oil pan . with everything out of place would i be able to slide the oil pan out through the back? or will the windage tray/ pick up not allow me to pull it out?
if i cant im thinking of doing the rear main seal. whats the easiest process of doing so ?
pulling out the rear cover new gasket for the cover and rear seal *gm products?
i remember having diagnostic code with a leak . iirc

i think you might have to lift the motor up a bit to pull the pan. i believe it hits the pick up tube.

Re: my LSx 87 IROC build
sorry no too many pics on the diffuser. when i have time im going to redo it i will post pics though.
for the exhaust yea its going to get cut/modded in order to fit. the exhaust i cut off the car ran around the transmission k member. it was a temporary exhaust.this is exhaust is all clamp on and looks like adjustments wont be too hard.

Re: my LSx 87 IROC build
cool as for the oil pan gasket i might hold off on it.
might just be my rear main seal. when i first did the swap i don't think i put any silicon on the end were the oil pan and rear cover meet when i did the rear main seal
i do have a hairline crack in the front that has a temp fix with aluminum epoxy. it has been holding pretty good. im looking at ghettocruiser thread and he used a tool that holds the engine in place while beign able to drop the k member.
i am thinking of doing this during summer. notching the k member for better clearance and painting it.
thanks looks like this might work!

Re: my LSx 87 IROC build
hey the tool worked out great. easiest method that ive used so far.
clutch is in. i had a hard time today.
my gm seal started to have a lil wear and tear so i bought a complete felpro rear cover seal kit i should be ok.
one of the longer 10mm screws that tighten the lower portion ofthe rear cover closer to the oil pan broke on me.. bad day
for the so cal hardcore tpi guys who check my updates..
still a stock cam guys



new" style hat on the release bearing.

test fit of the exhaust. *hoping to get away and avoid having to buy a relo kit.

second time having an issue finding the correct dexron3 fluid for the transmission .. i will wait and talk to a gm parts rep

Re: my LSx 87 IROC build
few updates. updated pics and info dual over the axle 2.5 all stainless steel set up. it is still a 2 1.4 piping up front up to the x pipe merge that turns into a 2.5. *temporary set up until i decide to do ssw headers.
i have a ses code that hasnt gone away for a while. code p0300 . random misfire which i cant find the problem. car runs normal. any suggestions?
car sounds great and i will be posting sound clip soon.
i found some very cool custom exhaust tips on a vette forum. i dont have much info on the tips but by the looks of the welds from the rear looks like someone built them for a c5 or c6
i have about 150 miles on the monster clutch . chattering was pretty annoying at first but after the 50 miles it decreased. but the clutch feels great overall!
i had issues do to my pilot bearing but it seems like i can go through all gears once again. im waiting for the 500 mile break in and ill put the car to the test against a local ls2 gto in town and a fully built tpi that has been impatiently waiting for a run
also installed some h3 8k hids for my fogs
to do list:
new a/c compressor and condenser
notch k member rear portion & new oil pan
warranty koni & realignment
ssw headers
sfcs
tires!!
thinking of doing a cam swap !
few more pics of the rear air diffuser dimensions are now 20" x app23" long

I've been wondering too. I just looked in the '06 GTO Helms and Dexron III is the specified lubricant. Why exclude Mobil 1?

I've been using AutoZone brand dextron III. I don't see what the issue is with using cheaper stuff, it's made to be a direct replacement?

Re: my LSx 87 IROC build
Yeah I ended up using some valvoline dex3. The original mobil 1 ATF wasn't available I didn't want to pay the gm price either lol they said to becareful and not to get confused with dex vi








100% agree, that is a very nice setup you've got there
