Re: Project: "BTA" Boosted Trans Am.....
Update.....
Preparing to make some much needed room for the turbo headers, and down-pipe(s), I eliminated the stock heater core tubing. In the first picture you will see just how much room this mod alone can make. In the second picture, you will see how I re-routed the heater core hosing to go directly to both the water pump, and the intake manifold. In the third pic you will see how I will be re-routing both hoses to run paralell with the drivers side valve cover, tuck in neatly behind the distributor, then up into the heater core inlets.....

looking good so far, i love how we have so much room to work with in these cars. haha i use to stand inside my engine when i was putting the new top end on.

Re: Project: "BTA" Boosted Trans Am.....
nice rob but umm those heater hoses are in the way of the driver side header,well they can stay but will deff need a heat shield to protect them
the smog pump also needs to go so i can get the passenger side header,and down pipe in.
remind me tommorow if we go to the track to grab u an egr blockoff plate

Re: Project: "BTA" Boosted Trans Am.....
how long before u get me those heads, im gonna take them out to a friend of mine's shop to be cnc'ed instead of me hand porting them.
i also need to talk to u or gasper about the cam,as im gonna drop in the larger intake/ex valves for ya but the chambers need to be reshaped a bit so base cr may drop upto .2-.4 depending on a few things

Re: Project: "BTA" Boosted Trans Am.....
Update;
From what my cousin just told me over the phone, track conditions don't look so sweet for this evening. I was hoping to have a naturally aspirated base run for everybody posted later on tonight, but it looks like it's going to happen this coming Friday (weather permitting, of course). I should have a few more mods done and posted by then though.
Stay tuned....

Re: Project: "BTA" Boosted Trans Am.....
Minor update;
Due to getting somewhat a little paranoid, cuz <cough cough> someone <cough cough> has a way of doing that lol, I altered one of the coolant hose routings. From the intake inlet, the hose now runs parellel with the passenger side valve cover. The water pump hose routing remains the same though. Raceway Park for tonight is still up in the air, as the rain looks as if it's ready to come down very hard soon...

Re: Project: "BTA" Boosted Trans Am.....
lol man am i having BAD day.she just came to pick me up,we get not even 2 miles from the shop and we got pulled over for suspended regristration..
dmv suspended the reg cause they said the car had no insurance,and of course they didnt mail a letter stating this happened.quick call to the insurance company verified the insurance has never lapsed on the car.
blah so tom = a trip to dmv main office to strighten things out
yeah its been coudly all day,but its only a 10% chance of rain for tonight so it should all be good

Re: Project: "BTA" Boosted Trans Am.....
With the smog pump now being removed, it is now mandatory to run a much shorter serpentine belt. The idea is to use the existing belt, wrap it around the pulley's as tight as you can (including the tensioner), then when your satisfied with the length, cut it as close to fit as possible. In the pic below you will see the existing belt cut, just how much was literally removed, and the now shorter belt "taped" heavily back together. There's obviously a reason for the tape....

Re: Project: "BTA" Boosted Trans Am.....
With the belt being held in place with the tape, you'll now want to take a quick ride over to PepBoys, Autozone or Strauss, and have them match another belt w/the proper length for you. The final result will be as follows;

Re: Project: "BTA" Boosted Trans Am.....
umm rob u need to reroute that belt. now the waterpump is turning backwards.
from the alt to the crank u shoudl go around the crank up over the water pump to the ps pump under the tensioner over the alt pulley
opps nm it is turning in the right direction but that belt will slip like that

Re: Project: "BTA" Boosted Trans Am.....
^ Definitely agree with you regarding the new routing of the belt, however, this required a much longer belt over the one I purchased (the one I went with is much to small for the above). Had to again use the original belt to size up a new one, which worked out to perfection. See pic;

Re: Project: "BTA" Boosted Trans Am.....
that tensioner looks liek its barley has any presure on the belt i would get one about 1 inch shorter so the tensioner gets pulled up a lil more.
its a shame u cut up that non ac belt,i would have bought it from ya lol,quess it really dosent matter though im ditching my smog/idler pulley anyway, so i would have needed the shorter belt anyways

Re: Project: "BTA" Boosted Trans Am.....
lol why didnt u just put a 15mm wrench on the tensioner and release it instead?
btw logs look like a go now that everything is all cleared out,but i need to take some measurements first to be sure

Re: Project: "BTA" Boosted Trans Am.....
Preparing to install the Intercooler(s) soon. Not wanting to "hack" up the Banshee inspired nose clip, I decided to eventually remove the front support w/lighting underneath the bumper, and install two separate Intercoolers (similiar to the LS1 ProCharger kit's) right behind the two openings....

Re: Project: "BTA" Boosted Trans Am.....
I wouldn't remove the front structural bumper if I were you. It holds the car together up there and supplies a lot of protection in case you run into something. Try to get an aluminum from bumper and/or remove the hood latch brackets and go to a pinned hood instead.
Tubular cross member or coil-over springs would save some weight too.

Re: Project: "BTA" Boosted Trans Am.....
Well, coming from someone who just hit a speedway barrier (me) I would say while the weight is not needed, the strength certaintly is! You might be able to make a lighter one with tube huh?
What were you going to do with the manifolds? I forgot if you've mentioned. I just saw pics of a TT 350 where the cut the stock log manifold and added a flange. Puts the turbo right were the alternator sat. Looked cool and easy. Would you have any luck modifiying a FWD manifold?

Re: Project: "BTA" Boosted Trans Am.....
Could you use a passenger side manifold upside down? I'm at work and don't have the parts in front of me. I think its the same though either way.
One more thing to try, I got tired of broken manifold bolts so I drilled/tapped my heads for 3/8" threaded rods. Might be worth it if you are going to hang a turbo off each manifold. Exhaust leak would be detrimental to your setup.

I'm glad your on it! Get some prelim picks up so we can all drool over it. My roommate is boosting his civic :rolls: and I may have to follow suit just so I can smoke him. We're a close race at the moment at N/A.

Just some minor updates;
Cruise control has been eliminated, as well as the bracket assembly connected to the drivers side exhaust manifold that held the fuel lines in place. Remember now, there's a reason for the bracket's removal. Also, the MAP sensor, as well as the coil assembly have been relocated behind the distributor, mounted on the firewall....

Re: Project: "BTA" Boosted Trans Am.....
Minor update;
EGR assembly has been tossed. Will be fabricating some block off plates out of some sheet-metal (as well as plugging up the exposed air tube inlet on the exhaust manfiold) that I had lying around for the plenum, and exhaust manifold very shortly. Disregard the stock coil, as I went with an aftermarket piece now residing on the firewall....
Looks like I'll be getting my NA base run after all. Strong possibility that Dave will have his '89 Camaro ready for this coming Wednesday, so it'll be, either, his boosted '89 vs my NA '92, or NA vs NA. Time will tell....

Even with the stock ECM trying to control boost, your Camaro should destroy my NA Firebird, so worst case scenario, just hook the stocker back up, and enjoy the track.
