My shopping list for you looks like this IMHO : new injectors, top end gasket set, coils, wires, Loco Bob's ported plenum & I/H's. I would consider asking Jerry about the fuel rail O-ring set that works for our gas with the alcohol in it. The next time I do my plenum pull I'm going Jerry's O-ring route....

Re: Ported Intake for Sale
Thanks Tom, I think I'll wait on the throttle body and horn 'till the heads are done.
Injectors may come from Jerry, he has the FIC's. I've also got a line on another set of the same that were bought by someone and never used. Coils and wires from Jerry. Yes, I'm sure Jerry will be more than some unknown sorce, but I'd rather support Jerry than my local Chevy dearler, or flea bay. Locobobs stuff. Gaskets from Jerry, I have some of them. Didn't know about fuel rail o-rings, are those the ones on the injectors? |

Re: Ported Intake for Sale
My apologies Bob....for hi-jacking your thread.
Steve, the fuel rail O-rings are all the o-rings at all the connection points in the fuel rail piping. Just ask Jerry to point out the kit. The injectors come with all the needed O-rings to install them, the fuel rail kit is a separate part. You are so going to love Bob's work and the results on the car! I'm envious. Hey, does your exhaust guy know how to weld stainless steel???? I need some welding done on my headers before I coat them. Tom

Re: Ported Intake for Sale
Thanks Tom.
Yes, he knows how to weld stainless. He does beautiful work. If you bring them, I can bring them to him, then ship them down to you. |

Re: Ported Intake for Sale
Steve, one thing that may have been unclear but these IH's have no secondary butterflies so unless you've already removed yours a retune will be needed.
Congrats on taking the leap, was eying these myself but have to wait for post-season to consider this level of project. Cheers, - Jeff

90~92 Originally, the 90~92 model injectors had a different external configuration, between primary & secondary. The difference only pertained to the bottom of the injector, both primary & secondary injectors flowed the same amount of fuel. The secondary injector seals, both top (fuel rail) & bottom (injector housing), were the same small o-ring, PN 17112222, and fit into a groove on the injector, created with a thin flange. The primary injector seals used the same o-ring seal, PN 17112222 for the TOP ONLY (at the fuel rail). The bottom seal, PN 10067600, does not install on the injector, but rather inside of the injector housing and seals on the o.d. of the injector, slightly above the bottom. The primary injector did not have a metal flange on the bottom to retain a lower o-ring like the secondary injector did. So, in summary, a complete set of injector seals, upper & lower, consists of 24pcs PN 17112222 (small O-rings) and 8pcs PN 10067600 (large O-rings). Today, aftermarket injectors, FIC, Accel, etc., are identical for both primary & secondary, i.e. they have the metal flange to retain an o-ring on both the top AND bottom. Herein lies the confusion for first-timers. Typically, a new set of injectors will come with 32pcs of the small o-ring, PN 17112222 and NO, zip, zero, nada primary injector lower o-ring seals, PN 10067600. Do not install the small o-ring on the bottom of the primary injectors. it will not hurt anything, but it does not seal and serves no purpose. if it is on the primary injector already, then remove it. 93~95 Lot simpler, same o-ring seal, top & bottom for both primary & secondary injectors. Jerry's Gaskets Combo Kits Speaking only about Fuel Injector Maintenance Kits (we offer several different Combo Kits, depending on the work to be performed). 90~92 http://jerrysgaskets.com/store2/root...roducts_id=459 This kit contains the following; Gaskets & seals included in this kit are as follows;
I have not been able to confirm whether the o-ring seals on other aftermarket injectors are Buna-N or Viton. We strongly recommend using Viton over Buna-N when ethanol blended gasoline is used, E10, E15 ,etc. IF new injectors are being installed, and they are furnished with new o-ring seals of a suitable material, then there is significant savings in ordering just what you need as opposed to the Combo Kit listed above. There is no need to purchase a kit that has 24pcs PN 17112222 if they come with the injectors. Instead, buy the remaining individual items separately. 93~95 http://jerrysgaskets.com/store2/root...roducts_id=455 Same as for 90~92 above..... if you are buying new injectors From FIC, no need to buy the Combo Kit. The O-rings that come with the injectors are Viton and ready to install. Save money, do not buy the Combo Kit, just order the remaining items separately. I hope this helps to shed some light on the different styles of injectors and the seal configuration, as well as different seal materials. If you have any questions, feel free to contact me.

Re: Ported Intake for Sale
Just an respectful FYI, Secondary port throttles (butterflies) are located in the cylinder head, not the injector housings

Re: Ported Intake for Sale
Har har har - clearly I need to take mine apart sooner rather than later!
And now I have to think about how that affects my class rules.... Thanks, - Jeff

Re: Ported Intake for Sale
Plenum and injector housings are here. They look good, thanks Locobob.
Pulled the coolant fittings tonight, as soon as the plugs show up from summit (thanks cliff) I'll drill and tap them. Injectors are here. Gaskets and starter are on the way. Thanks Jerry. Soon as everything is assembled, we'll have a party. |
