Ok im a lil comfused i dont know if i have all i need for the intake or what. It looks like it is missing a distributor hold down,the coil dont know how it bolts down?? I know its missing the distributor cover.Is there a list or somethin newhere that shows all the parts and how they go on?? and what sensors r what. Also whats that in the last pic geez i need a lil help on my tbi i know it was stock and everything was how it was suppose to be.

 

Looks like you've got yourself an '89+ TPI (no CSI hole in runners), so you should be able to use any external coil GM distributor made for the '87 and later F-bodies, C-1500 pick ups, etc, so long as you have the harness clips for that style distributor. The coil doesn't have to be anywhere in particular... Distributor hold down clamps can be had from SDPC for about a buck IIRC...

 

First I would take the whole thing apart and take the lower intake, runners, plennum, and tb to a mashine shop and get it beaded so it will be all nice and clean when u start.

Second you might want to send off the injectors to be rebuilt or you could just buy a new set of accel or ford injectors they are both in the low 200's for a set.

Some of your sensors look to be broken or pretty ruff. If they are broken or coroded i would replace them.

Not sure about the distributer hold down maybe u can use the tbi one?

Do you have the computer and harness if not you will need thoughs.

 

the last pic is of athe egr selinoid

 

in the second picture on the throttle body the top sensor is the throttle positioning sensor and the bottom one right underneath is the idle air control sensor not sure if thats what u wanted to know in ur question u asked.... what sensors are what.

 

wow guys that for all the help alrdy aswered alot of my questions so its a speed density intake then?

 

look at the pictures better guys it does have the hole for the cold start injector in the runner to your left and look at the intake manifold it has the sensor(broken off) for the thermotime switch for the cold start injector.and its a 87 and up look at angle of the intake bolts in the center.

 

oh sorry i have the cold start injector in the box and if a sensor is broken off thats no big deal

 

do you knwo for sure its a 350 or 305 setup?look at the fuel rail youll see a number on it also on the injectors theres a number on them,let us know what they are and we can determine what it is.

 

the guy said it was a 305 gta like an 88 engine the junk yards r ususally pretty sure when its a 350 cause they get more cash out of those. Ill have to check tomorrow when i get back from work 3rd shift ugh.

 

Oh also what r the sensors on the front of the manifold and what is the name of the sensor u said was broken off. Whats the names of all the sensors u think ill need. Is there a webpage or something newhere that shows it apart and all the parts like a diagram?? Ne1 know a good company to buy all the sensors from ,gaskets,injectors maybe they have a kit?? I think i might get my tbi harness made for the tpi what company is good at that. Thanx

OK went and got some numbers here r a few off the top of the fuel rail
0237 JYD
17087254
75
81467
Here is the manifold casting number if it helps i think its right it was hard to read
10088015

 

DOH! Sorry guys!

BTW, unless you get an OEM harness (which can also be found on Ebay), get a Painless Wiring harness. I worked with one of those on a friend's S-10 and it really was painless!!!

 

is 17087254 actually 17087264 if it is it's a 87-88 305 rail, and it should have come with multec injectors according to my fuel injection specialist manual that came with my ecm & harness, how reliable there charts, who knows

 

im pretty sure i wrote it down right. I want to get rid of the 9th injector what all do i have to plug?? Can i just get 89-92 runner and that be it and plug the fuel rail??

 

yeah my tpi swappers guide doesn't have a 54 only 17087264. IT says for 85-87 f-body 5.0L multec injectors.

 

i dunno i can recheck tomorrow

 

spd

do what I did, repin a mass air harness to run a speed density ECM, its not to hard

 

I see you've got a 90+ TBI car. The best bet is to repin your existing harness for a 730 and add the additional injector plugs.

You'll need a yellow 32 pin connector to do the 730 thing.

Wiring diagrams can be found at the www.diy-efi.org FTP site. Or I can send you copies via email. cheers, BW

 

yes its a 6 17087264
also that tpi swappers guide does it tell u alot and show some good diagrams?? Another thing will i need dual fans? I also want to delete the emissions i think
Here is the setup i been thinking of 383 4-bolt, Pro lightning heads,TPIS big mouth intake,SLP runners,Com cams 306s cam,roller rockers,afpr,hooker shorties

 

heres a website to help you out alittle bit
