#1. you HAVE to use a 85-88 style TB to clear the fuel rail correct?...if so isnt the linkage different? What do you do to fix that?
#2. so any aftermarket AFPR will work as long as they are made for turbo buicks.
#3. these ports are Fed up right? see attached pic
#4. how do you remove the injectors in the attached pic? i was told they were #30 injectors but i have no way of telling if it was the truth bec the guy cheated me
#5. will bbk throttle bodies fit? Would it be better to use a holley TB since its a holley intake?
simply enlarge and really look at the edges its NOT the fuzzy effect of the camera...the edges arent straight in some parts and look rounded off instead of a 90 deg edge...WTF gahhhhh

Answer: Nope, I am running a TB for the 89-92 cars. Easy fix just run the fuel lines differently that what Holley recomends. I have my crossover tube in the rear, FPR on the drivers side rear and feed fuel from the passenger side front. There are pics on here of that routing.
#2. Sso any aftermarket AFPR will work as long as they are made for turbo buicks.
Answer: Correct...however an aftermarket adjustable regulator is next to useless once you can burn PROM's. Save your money and get the prom burning equipment.

Answer: To remove the injectors you need a hex bit/allen key to remove the 4 bolts, two each side, that hold the fuel rail to the intake base. The bolts go throught the fuel rail into the intake runners. Then all you need to do is pull up on the fuel rails and the injectors will pull out of the manifold. You them tjust pull them out of the rail. From the pic they look like stock injectors from an L98, however you need to have them flowed to be sure. Cruizen Performance provides this service.

Answer: Any aftermarket made for TPI/LT1 engines will work, just need to be creative. See post #1.

Answer:The odd looking ports you are refering to is basically the norm for all cast parts. What happens is called casting shift. Basically when the part is made the things start to move around as the aluminum is poured. That is why most serious racers have their intakes port matched to the heads to allow the best possible flow. This porting cleans up the irregularities in the casting which makes the ports identical looking from runner to runner. This also opens up the ports a bit reducing turbulance and makes for a better flowing manifold.

thx for the help
Fed = F-ed as in f@#Ked up
i had a stealthram previously before this and the ports looked beautiful with nice clean edes and even all the way around...while this one is all sh*tty looking thats why i was saying that...you can see on the edges of the port wall in the pics (its a little fuzzy) where the port isnt straight...i wouldnt doubt for one minute if they were completely stock injectors...AC398 is a damn liar

Well no the ports aren't the greatest but they can be cleaned up very easily and it is not uncommon to see this in an intake. Also those injectors could be 30lb/hr Holley's judging just by a picture is very hard. Here is a link to holley's injectors...these are 19lb/hr but Holley used the grey on black paint for all their injectors including the 30lb/hr: http://www.holley.com/522-1908.asp

I am using a later (newer) style version of the BBK 52mm TB. Was from a 95 LT1 setup with the newer TPS and IAC. Finally got all that wired in nice.
The throttle doesn't hit the rail like some of the others but haven't been able to use the stock TB bolts cuz they hit the bottom of the TB housing.
Need to get some SHCS or something to bolt it on with and check that the throw on my throttle (pedle stroke) is going to work ok.
The tops of the ports look like mine in that there is not allot of room for error on the intake gaskets. Ports are almost uncovered because of the rounding in the casting. They have now added more material to the tops of the new manifolds to help with that and porting to the 1206 heads.

that does look exactly like them but i know there is not many ways to tell besides having them flow tested and i dont have time for that..i did see some letters on the sides of them..initials RP and W 55 and W D...i have no idea i hope they arent all diff injector sizesOriginally Posted by Slow89Iroc-Z

i do have a number on them 7223 17095004
i believe i just found out that they are Rochester injectors due to that part number...all ive found them for his very high flow rates not 30lb/hr like 59lb/hour
so after a little searching it seems the number matches up with stock lt1 24# per hour injectors made by rochestor.
NOW a new question...do i really need all that for a lightly modded l98...i plan on running headers, the hsr intake, and maybe a chip so i can just get a regular FPR instead of a big expensive AFPR and have a good tune at the same time.
how much would a nice set of these go for?

well i think im gonna keep the injectors bc with the added rpm range and air into the motor more fuel will be necessary...has anyone tried spacers on the HSR? i know it sits high enough as it is but im just curious if it would work like a carb and produce results
