Guest Anonymous Posted July 27, 2002 Share Posted July 27, 2002 i have an '82 zxt w/a p90a head and T04b turbo...i've bought an hks add inj unit....s'posed to let me add up to 6 inj (and control them). ..i wanted to have 6 stock injectors added to the manifold but have never found the stuff to do it...(theres a pict in maximum boost of an L28 w/2 fuel rails and 12 inj like i wanted to do). ...i have found a 2",Y pipe that hks makes (has 2 inj's firing down a 50mm pipe)...prbly s'posed to go before the throttlebody...but i was thinking about having 3 of 'em welded onto the manifold (on the side that the j-pipe runs down) firing toward the head.... ....i know i wont need 6 inj. but i can get 6 of 'em for $70 and thought it might give 'em a good duty cycle and better distribute the fuel.. .....anybody have any ideas about this?....i'd still like to mount them on the manifold in a straight row 3" or so upstream of the original inj's if anybody knows of anyone who can do that for me....but if not what about the Y pipes? thanks, s.neihoff Quote Link to comment Share on other sites More sharing options...
Cody 82 ZXT Posted July 27, 2002 Share Posted July 27, 2002 There are several sites you can buy the injector housing from I think HKS may be one of them. You would just need to buy the aluminum ones and have them welded on. Some are even the thread in type but, I don't think that I would go this route. Seems like they would leak over time. You could just take the pic from the book to a machine shop and ask if they can do it. You might have to try a few to find one that can and is really willing to mess wth it and do it right. As I'm sure you read in Maximun Boost the extra injector upstream of everything is only good for a few more PSI. I guess it depends on how much power you are wanting to make and how perfect everything has to be for you. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted July 29, 2002 Share Posted July 29, 2002 ....thanks for the reply.....i'm trying to get to 300-350hp.....i know it would be a lot better w/a programable engine engine/fuel management system but i dont think i'd ever get it to work....so i figured the programable aic (that i could just turn off)and make everything stock again...would be my best bet.....s Quote Link to comment Share on other sites More sharing options...
Scottie-GNZ Posted July 29, 2002 Share Posted July 29, 2002 i know it would be a lot better w/a programable engine engine/fuel management system but i dont think i'd ever get it to work Why is that? That is the only way to do it correctly. so i figured the programable aic (that i could just turn off)and make everything stock again...would be my best bet.....s Not as easy as you think. Remember, you are dealing with the stock ECM and AFM! Quote Link to comment Share on other sites More sharing options...
z-ya Posted July 31, 2002 Share Posted July 31, 2002 I agree with Scottie, just do it right and get a programmable engine management system. The money you are going to spend on the AIC, machining, welding, etc. could be put to better use on a new EFI computer. If you use the AIC, you still don't have any control over timing either, a must for a high HP turbo motor. Pete Quote Link to comment Share on other sites More sharing options...
Tony240ZT Posted July 31, 2002 Share Posted July 31, 2002 If you already have the fuel AIC and the Y pipe I'd just try that out. That would give you a chance to see how well the system works before you invest money into modifying your intake manifold. Just put the Y pipe right before. If you find out later that the system isn't flexable enough for your needs then you can opt for the stand alone system. You may find you're happy with the 2 added injectors and the stock AFM/computer. Personally I've had many troubles trying to get a lot of horse power and keeping my A/F ratio correct with the AFM.

Guest Anonymous Posted August 7, 2002 Share Posted August 7, 2002 ...i was concerned about venting fuel injected air back into my system (with my bypass valve)if i put the y-pipe before the throttlebody.... ....this thing looks pretty versatile...it monitors rpm , boost curves, duty cycle and computes the fuel delivery...or it can be programmed to do most of what needs to be done as far as getting more fuel in there...doesnt do anything about altitude or temp...(or doesnt appear to)..... ....i dont have to have the fastest car in the world....i'm not gonna race it or anything....90% of the time stock is more than enough... but i wanted to get a little "extra" out of it...(and to learn about it).and it seemed like a good stepping stone toward that...eventually when i learn a lot more i'd like to put in a whole new management system but i lack the smarts to do it right now ... ....and i have to get this thing through "smog" or it doesnt get legal....if i turn this box ..off... its inert and i (or whoever i get to work on it)just has to deal w/a stock 82zxt .....s Quote Link to comment Share on other sites More sharing options...
