I've noticed looking at several pictures of TPI engines while in the car that they seem actually less cluttered then the V6! Where's the whole EGR setup? What about the vaccuum lines? Maybe if you guys posted some pictures it would help, I'm just wondering here. Still can't wait to get my hands on the new Formula...

The EGR on a TPI setup is located on the intake manifold below the plenum! Between the manifold and the plenum!! Below is a picture of Madmax's siamesed TPI intake! The plenum isn't sitting on top of it but you can see the EGR valve clear as day! Hope that helps a little!

 

Thanks for the detailed response! WOW! That's impressive. If you guys want a good laugh or at least a head scratcher, look a an LB8 2.8 MPFI sometime. Vacuum lines running EVERYWHERE, EGR hanging off to the side of the block, just one big PITA! If someone would have told me the L98 was just designed more simply, I might have stepped up a while ago!

It helps to have the AIR crap removed

And removing the air conditioning helps alot...


Of couse the ol trick of flipping the injectors so the connector faces the inside completly removes all wires from the valvecovers....

But it would suck if something went awry with the wiring... I would have to take the plenum&runners off..

Those are a couple of clean looking motors! You've mentioned the AC and AIR stuff, but have you removed anyhting else to make it look that good? Also, what are the components of the AIR system? I've removed AC before, so that stuff I know.

-Reno

 

Damn, is that an aftermarket intake that's been made siamesed, or is that the stock one done up? Some people say that the stock one doesn't have enough material to remove to equal aftermarket ones. How much does machine work like that cost, or is it something you can do for a dremel? I'd imagine a dremel would take a VERY long time. Thanks.

That is a STOCK TPI intake done that way by "Madmax"!! There is PLENTY of room to port a stock intake! There are DYNO charts and numbers from runs done WITH this intake at the link below! VERY impressive!! He doesn't recommend using a dremel on it but I think I'm gonna try an electric Die Grinder on mine!

The AIR system is bascially all the smog equipment to keep the car legal! The AIR stuff is mostly what clutters up the TPI engine but can be easily eliminated! It consists of a cylinder type plastic device and some rubber hoses on the passenger side near the front of the valve cover, a LOT of metal tubing that is attached to the exhaust manifolds on the drivers and passenger side and clutters up stuff A LOT, also there's a smog pump located on the lower front passenger side of the engine that is eliminated with the AIR stuff!! The AIR tubing attached to the manifolds is easily eliminated by putting NON-emissions legal headers on the car but if you want to just get rid of the AIR stuff and keep the manifolds you can cut the tubing off the manifolds and plug the holes really well with something.... like maybe bolts!!

The engine compartment under my hood is completely stock minus the AC Pump (compressor is still there), and some of the AIR stuff is gone but the tubing to the stock manifolds is still there until the new engine goes in! I took some pictures today but I don't think I took a good enough one to show you where all the AIR "crap" is located!!

 

Reno,

Out of the box, they are not that organized, but not terribly crowded either:

Very clean, Vader. How's you get all the hoses back to a glossy black like that? Using armor all or something?

-Reno

 

Vader,

what is that thing right by the windshield washing fliud? Looks like some vaccum lines going to it, b/c i dont have it what ever it is.

That looks like the cruise control unit. Anyone want to back me up?

-Reno

 

Its the cruise control.

I see my pic is all over the place... lol

My TA used to look like Vaders under the hood, till I ditched that square plastic airbox. Getting rid of the air injection system really cleans up the engine compartment, and makes it easier to get to the plugs. That is the only reason to remove it. You can also move some wires and vacuum lines to places they arent as visible if you are creative.

I definatly compliment vader on the originality of the motor.

Working on a stock motor looks complicated, but often it looks intimidating because of the 'work' the peson who owned the car before them has done (Replacing formed lines with the 'universal fit' lines) snaking them all over the place, ect....


I retained all my stock parts (smog, air, ect...) just in case of emissions in my area. Alot of people jump the gun and yes, I could get my car inspected w/ emissions if it did come out, but... but... (You get the idea)

Plus the fact your 3rd gen will be worth alot more with all emissions there is definate. At least holding on to the stuff is worth it (I threw out my manifolds and now can kick myself) and getting 'stock'(GM) type hoses would not be a bad idea to hook it all back together because these cars will be worth a hell of alot more than a 1st gen camaro at the same age span because noone takes them serious with originality.

Like for example, a guy at a car club I attend has a stock aerocoupe monte with the original 305 and everything (smog) hooked up and you could tongue every hidden crevice of this car and come up empty. It's beatiful! It has less than 20,000, it's also very slow, but find anything to compare with would be almost a joke! It has more trophies than I went trough socks!

Well, I guess I can't be a fortune teller, but the way I see most third gens treated, they will follow the legacy of the 1st& even the 2nd (although the hype of the 1st had everyone saving the second, with the third? No hype... Not even yet, almost 2 decades later)

 

OK, I'm stumped........

What is the plate mounted on the REAR of the plenum? I see the cover plate (The 'Tuned Port Injection' one) on the front. The rear plate on mine is missing?

Is that a problem? Was it removed by some bozo long ago just to get to the plug wires?

Can I get another?

RB

 

On F-bods its a piece of plastic, as shown in the pic. The Corvettes got one made of aluminum, and if you are going to get a new one you may as well get one of those instead of the plastic part.

 

the plate is a distributor cap cover and is made of plastic on all camaros and firebirds on the vette it is made of metal

 

I think that the plastic peice is called a Plenum extention cover?

I'm running the accell extension housing. It ends right where the plenum ends, but leaves the distributer exposed. (Little dark in the pic)

 

Joel,
What air intake kit have you got on your car? I've been looking one for my TPI for a while.

 

That's the stock intake for an 88 Formy. All parts with the exception of the MAF to airbox hose are still available at the dealership.

It's not stock...

SLP siamesed runners fully divided with a stock base siamesed part way and egr bleed holes epoxied shut, EGR still functional. Fully ported plenum for 58mm throttle body. Screens and fins removed from MAF. Cut two windows in the air can. K&N cleaner, afpr@51psi, 24# SVO Injectors. TPIS Stage 5 chip [man I got raped], ZZ4 bottom with 1.6 RR on Morgantini ported heads. SLP 1 3/4 headers, no cat, SLP cat-back.
Auburn pro-posi with richmond 4.10's.

Runs mid to high 12's on a good day. Around thirteen's on bad days @ 2,200 ft.

 

When he said "intake kit," I think we all thought from TB to air box, which is the stock design, right Joel?

-Reno

------------------

I'm sorry, but that's what I meant.... the intake from the TB to the airbox. Thanks for making that clear

 

Yep. Thats the stock ducting. Seems to be half decent so I never got an aftermarket one. I think there were a couple different designs of these (some had dividers or something like that)

 

hey joel,
did you have to use the shorter exstention cover with that accel coil? I have an accel coil but I want to use the original cover. I haven't got the phlenum on yet so I didn't know if it would work or not.

 

If you want to use the Accel Supercoil it would be best if you got the extension from Jegs. I had the stock one on mine for a few days and decided it just looked plain stupid because it slanted up because of the height of the coil, and ordered the shorter extension.

 

Are you talking about the coil in cap accel coil? Just take the plastic cover off of it. Mine has been that way since 93

 

It's just for apperance purposes...

With the plastic on it slants up and looks out of place and with it off there's a blank spot that makes it look like it's missing something...

It doesn't do anything though... Just a 'pretty' part.

 

Hey Joel, just a BTW, that is a wild looking engine. Must keep it really clean, huh?

-Reno

 

This one's not much fun to keep clean either...

It is the Accel Superram, but I have a billet lid, and the whole thing is polished.

Ummm.. I just have to wash mine w/o getting all the sensors wet.

That looks like alot of polishing... I was going to do something like that, but I hear that clear paints/powdercoats make polished surfaces look like hell, so it's mag polish every so often with some elbow grease i'm sure! Now thats alot to keep clean!

 

Who, here, has a pic of a 1989 Trans Am with the Ram Air hood set up?
I've been trying to see under the hood of one. No luck yet!
Hey Reno, They're real good to ya!
That 1988 engine bay looks exactly like my 1985 V-6 set up, coffee can air intake, to the black plastic box to the throttle body.
Can't believe that gets enough air, either!
