The hardest thing was changing out the fuel pump. I made it a little more difficult than it had to be. At the time I thought I only had like 2-3 gallons in it, so I siphoned and it stopped at like 2 gallons. When I got the tank unbolted it was pretty heavy, turned out I had ~4.5 gallons left in it. The whole job took me around 7 hours to do. Dropping in the engine was also difficult, took forever to line up on the trans.

Well on the motor now, the battery is charging have everything hooked up. I will try to start it later tonight. Hopefully it will start right up but with my luck I will have some electrical problems to sort out. Can't spend too long on it tonight, summer school starts tomorrow at ASU, fun.

 

yeah thats why I want an inline fuel pump if I ever go over to tpi. No need to take out the tank.

 

Is that a Stewart Component's Water Pump? It looks like the exact same one I bought for my 400. Did you have any clearance problems with it and your acc. brackets? My pass. side bracket needs to be shaved a bit so it will clear the pump, and the drivers side bracket needs a little clearancing due to my Tavia timing pointer, and it looks like even after thats fixed, it may hit the pump as well

 

I rwecently did the same swap and encountered about every wiring problem you could imagine. If you have any questions just let me know.

Did you have those heads flowed before you bolted them on? I 'm dying to see how those heads flow.

 

I disagree with you there. I think it looks just as hot in the car as on the engine stand! Great looking swap!

 

Oops, double post...

 

Yeah, it’s a Stewart stage 2 water pump. I had no fitting problems, I can dig up the part number if you want.

No, I didn't have them flowed. The castings looked great though. Their is a guy that posted his flow results on the Aftermarket review board. I think they were 2-3 cfms higher than pro topline's website. I also was expecting having some electrical gremlins to work out but the car started right up (after I fixed a slight regulator problem). The only problem I have found is that my gas gauge stays pegged on full even though I only have like 4-5 gallons in it. Please tell me I don't have to drop the tank again!!

Thanks a lot. I guess it looks good, but it was spotless on the stand. It definitely looks MUCH better than the old 305 TBI

 

Stewart Components #23123, right? I'll try to snap some pics of my interference tomorrow. Maybe they changed something? My pump was a brand new casting, it was backordered for a couple weeks while new ones were being made.

 

Great looking buildup? Just curious, are those Pro Topline heads iron or aluminum? I'm going to go with the 180cc version, but I'm trying to decide between iron and aluminum.

Also, did you have any work done to the heads (porting, etc), or are you using them strait "out of the box"?

take care,

Jason G

 

I am running the 200cc iron heads. I did not do any work to them, they looked great out of the box. Hopefully I can get some dyno numbers soon.

Here is a pic of the completed engine in this thread https://www.thirdgen.org/techbb2/sho...readid=185458. I just need to replace my coolant and wiper tanks.

 

Those look like aluminum heads???

 

Nope, Iron. I wish they sent me aluminum by mistake, but these heads were too heavy to be aluminum.

 

Well, they look like aluminum anyways! If they are indeed iron, I would paint them with high temp engine paint or they are going to rust bad! Have you driven it yet?

Mike

 

they are going to rust? why?

 

if they are bare steel with nothing on them they will rust.... i have world products sportsman 2 heads on mine and i clear coated them,still look like new.

 

Not yet, I have just started it. I only get a round 1 day a week to work on the car so progress is slow. I have been trying to get a friend to come over and weld my exhaust and LCA relocation brackets up. Should happen this weekend. Thats all thats left.

I don't think I will have to worry about rust out here in AZ. Its rare for our humidity to go above 5%.

 

how soon do they rust, mine have been on for 3 months or so, the iron ones

 

Well, the car is finally on the road. I have a few bugs to work out though. After 3k rpm the car takes off, I have yet to give it more than 1/2 throttle. This cam has more low end than I thought, completely drivable, no low vacuum problems (brakes/power steering).

I think I have a dead cat converter though, when I was putting my exhaust back on I could hear some rattling in it when I shook it. Sounded like something was kind of just rolling around in there. Also would a dead cat quiet the car down, I think my old engine was louder. So I will probably end up replacing it.

Also I don't have the speedo hooked up right now so this probably causing my problem. Some times when I am driving and engine brake to slow down I get an SES light. Then if I let the car come to an idle it will die.

 

I assume you have a VSS since you said the SES comes on. I had the same sounding problem with light coming on and dying at idle before I hooked up a VSS after I swapped in my 383/TH-350. I also got the SES when I drove at RPMs higher than 3000.

 

I did some searching and I think that my problem should go away once I get my speedo hooked up. The car drives fine when the SES light comes one, it will just die if I let it go to idle.

 

how does the power feel compared to the old 305 tbi?

 

The car runs totally different. Pulls like my R6 does .

 

I currently have the setup that's in my prof and I'm making about 380hp, so with the stealth ram's numbers, I would expect about 450hp for me, you should be higher. I have some questions for ya about changing the TBI Over, if you could drop me a line, RSCamaroGuy92@yahoo.com it would be greatly appreciated.
Thanks

 

The HSR is designed to give a 'lil less torque than the TPI but better mid-top end so its basically perfect for our cars, since the rears are light and we spin ALOT!!!!! That thing you have there not only looks AWESOME, but I think you might even see 11's?? Crazy, maybe, but It could happen.

 

That’s the number I am shooting for.

The hardest part about the swap from TBI to Stealth Ram was changing out the fuel pump. It’s all pretty straight forward, just take out the old harness and put the new one in. It will look a bit overwhelming when you see the harness outside of the car but all the wires run to the correct places. You will have to relocate some sensors but that’s no big deal. Also you will need new fuel lines, I just got some fittings and cut the fuel lines near the Trans and ran braided lines to the fuel rails. Here are the parts I used, which is all you should need. If you have any questions just send me a PM.


3 Aeroquip -6AN Straight swivel fitting = $17.97 ($5.99 each)
1 Aeroquip -6AN 45 degree swivel fitting = 16.99 each
1 Earls Hard tube adapter -6AN to 3/8" = $9.69 each
1 Earls Hard tube adapter -6AN to 5/16" = $9.69 each
1 Aeroquip -6AN steel braided hose 6ft = $27.99 each

Total $82.33

By the way cutting that braided steel line is a pain in the ***. I recommend you practice a few times by cutting several very small pieces off the larger one.

 

To cut the braided line just use a cut-off wheel in a die grinder, works like a charm. No practice needed.

 

I used a dremel high speed cut off disc, but the first 2-3 times I messed up some of the steel threads and couldn't get the fittings on. If you wrap the fittings in some tape tightly it will also make it easier.

 

Cut off wheels are great, but in a pinch, a sharp hacksaw works fine too. I agree, wrap the hose tightly in tape...

I never had much trouble with cutting the hose, just getting it into those fittings for the hose ends can try anyones patience...

 

Thats right, wrap the end in tape, how did forget that!!!

 

I have a 383 coming my way and i have a 305 TBI, and I need to change the fuel injection. Everybody talks about the HSR, did you get the whole deal with the 950 commander and what not? how much did that run you?

 

I did not buy the whole kit. I pieced everything I needed for just over $900. Going with the commander system would be easier to do and tune, but much more expensive. I think those systems run for around 2K. Here’s what I did.

Stealth Ram manifold/ AFPR/ fuel rails: $480 with discount. Thunder Racing
Holley fuel pump: $155 thunder racing.
Ford 30 pound injectors: $150 Ebay, but you can find way cheaper smaller injectors ~$30
Speed density ECM/Harness: $120 thirdgen.org classifieds
Stock 48mm throttle body: $30 thirdgen.org classifieds.
Throttle cable/bracket: $0 got from a friend.

 

JR

You still need the die grinder? Never heard from you over the weekend. Let me know man Ill help you porting it all out as well.

Anyway, got the new motor running, damn it is nasty!!!

Cant wait till fall, you and I will have to roll arounf ASU preying on Cobras and LS1s, those little rich bitches!!!

 

OMINOUS_87 sorry about that, you were right though the ports lined up pretty well. So I didn't think it was really all that necessary, maybe if I had pulled the heads and could have ported them, but not going to do that for a while.

Good to hear that your motor is running. Do you have it on the road? I still have some bugs to work out on mine, I think I have a vacuum leak some where, and still have to get my AC back together.

 

She will be on the road this weekend. I broke 2 of the trans crossmemember bolts off when I pulled the trans, so all i really can do is idle it around the block. A friend is picking it up Thursday and trailering it to his shop to get the bolts out, with a torch. Otherwise I am good to go, almost, my starter crapped out 2 days ago, got a mini coming from Summit here tomorrow. My AC system is flushed converted and ready to go, all i need is some vaccum on it and a few cans of R134. I also need an alignment.

 

I sure have been thinking of getting the stealth ram system for my 86 trans am, it already puts out about 420+ hp at the crank, what do you think the stealth system could do for my car.

I forgot to mention my car is already set up for the weekend drags, I built my car to handle much more than 400 hp. it has been put on a diet and has lost a little over 100lbs . the car can get into the low 11's on a good day at the track, would like to getinto the 10's

 

This thread is 2 years old. You should have started a thread of you own....

 

LOL I'm still waiting for some numbers lol j/k
