OK, so after searching for days, I've got the ball rolling on the HSR swap.

Aside from the searches, i have some questions and just want to go over my set up.

For one, i have a smog set up and my hooker 2055's have the AIR tubes. I was wondering how this (HSR) would install on a smog car? Do i need to remove smog items?

My car as it sits now has a stock '89 350 with MAP and smog (bought camaro in California) but now i live in Florida. i have a full exhaust- hooker 2055's and catco cat with 3 in magnaflow exhaust. The heads are cast iron (stock) but have been gone through at a machine shop and worn parts have been replaced. A T5 and 3.45 gears will compliment the rest of the drivetrain. I also have a PCM chip that was made for me because of the 5.0 to 3.50 swap. I'll send it back to get reburned after I put the intake all together and know what aftermarket parts i have compiled. I know a tune will bring out the best of it all.

Im not sure if the stock injectors work but i was willing to try a bigger size. Don't want overkill so if anyone wants to share the route they went with that would be cool. I'll be ordering all the parts real soon and will post some pics!
Was going to go the TPI route but now I don't have to worry about CARB soooo
Going the cheaper more effective route.

 

Intake install is not going to affect the exh (AIR ); keep or remove as you wish but the HSR has no EGR provision

 

OK, thank you for your reply. What i intent to do is just have smog removed when i send my prom back to PCM. I just wasn't sure if my engine will still operate with the smog pump but i guess it will as long as the info is deleted from the bin. Maybe later on, ill switch to a smog delete.

So far, so good- i've been reading a lot of threads. However, Orr89 made a good thread, but i cannot see his pictures that he posted along with his documented swap.
So far this is where I'm at.

In the back of the HSR there are 4 threaded port holes. Im not sure where the hose in pic 2 goes, but am i supposed to change the nipple and screw it into the back on the plenum or does it go into the manifold?

 

the hose in the second picture will hook into a vacuum port, it provides vacuum to the brake booster, I would look for a hole in the intake that fitting will screw into

 

I realize that's a broad answer, if you install the upper portion it might help you with what hole is correct, I cannot remember the correct hole at the moment

 

I needed a new brass connection 1/8" barb to 1/4". I found on another thread which size brass fitting i need. Thing is I cannot see very many pictures at all in previous threads that have been started to show swaps.
Most pictures are of just a one-shot final setup.
ill post more pictures up soon. Hopefully I won't run into anymore problems.


So far the mods with the HSR will be

-kirban AFPR
-full exhaust- hooker 2055's
-Magnaflow cat back
-3.45 gears with stock 5 speed
-ram air intake (gutting that out next as i heard airflow restricts where it bends over radiator)
-Stock heads but they have been gone through. All components are new.
-stock injectors
-stock TB

Hopefully these mods will support the power band and I'm looking to put a set of 1.6 ratio RR since i hear that smaller cams respond well to this mod.
My cam is stock as far as i know, in an 89' L98 engine.

One big reason I got the HSR if because I can us it to support a lot of power in the long run. So, after this bolt-on ill be looking at a fresh engine build, and then transferring the intake setup to the new long block. This is when ill do head and a cam at the same time.

 

One small vac port to the FPR ,
one to the check valve on the HVAC /CC line
Large port to booster.
The IAT can go in rear as shown or in the stock location under the plenum ( harder to access if you have to R/R )
If you have clearance problems you can put a 90 degree fitting under the plenum and run the booster hose there

 

Thanks oz, that picture and post helped me out. HVAC/CC line?
I don't have AC connected at this point…should i just cap that off then or connect it to
the check valve anyways? thanks.

 

well, here is the route i took and also the final assembly. I used a lot of threads on here that were previously documented and I appreciate all the help and knowledge everyone shared. Hopefully this can help someone in the future also.

 

IIRC this module bolted onto the side of the stock intake of the TPI, I'm not too sure where it can be mounted best except the firewall since the wire that connects to the middle of the distributor won't allow it to be mounted too far away.
next was the fuel lines, i used 120° bends and routed the send line around the back of the distributor. Return line also points back off the AFPR. Wasn't a fan of the wacky line set up that people had with the pro products fuel rails. Went with holley fuel lines and ditched their AFPR and got a kirban instead. part # 6547










Stock fuel injectors wouldn't work, so i ordered bosch 22# injectors from south bay fuel injectors. If you get them, make sure you call and tell them you have a HSR intake, because you do not want the ones with the adapter they're too tall for the rails and won't bolt on. I used my stock throttle body but had to cut off a piece of the (cruise control?) bracket since it was hitting the driver side fuel rail. A little bit of love with a dremel solved that though.

 

thats the coil , u can cut and extend the wires and mount it on the passenger side on the center intake bolt holes i think i have a picture of mine let me look
