Hybrid swap
Okay so I have almost everything I need for my hybrid swap just need to clarify some stuff. I got my parts off a 3100 engine I think it was a 98 since that was casted on the ends of the lower manifold. Any way I have the pistons from the engine as well im curious if I will need to bore my 2.8 in order to accept the 3100 pistons and if I will also need to use the 3100s connecting rods or if the 2.8 connecting rods will work. Any and all responses are helpful thanks

Re: Hybrid swap
If you are using 3100 pistons you will need to use a 3.1/3.4/3100 crank too

Re: Hybrid swap
How goes the project? I FINALLY got my 3.4/3500 up and running in my 95 camaro. That thing will MOVE and I haven't even got the tuning on it completely dialed in. Can't wait to supercharge it!

Re: Hybrid swap
quick question im looking for a 3.1RWD crank i know they have 3.31" throws will FWD 3100 crank also be the same throw as the rear wheel drive Variation because those are the only ones i can find in my area and i really would prefer not to hash out 500 bucks for a new one. im boring my block .060 over and would like to utilize a better crank for more CI. I know this is probably getting annoying lol, but your help is very much appreciated.

I used a 3.1L (gen2) crank in my '87 S10 2.8L block when I built my Franken60. The 3.1, 3100 and 3400 all use the same crank (RWD 3.1 might not have the crank trigger slots machined, but that's not an issue for what you're doing), so you can use a crank from any of those engines.

Re: Hybrid swap
A little update since I haven't posted in a while I got a donor Engine for the swap in case I potato something, its a 3.1 out of a 1990 camaro with120,000 miles. It was definitely a Pennzoil engine with the very large build ups of wax in the valley. Despite the build up the bearing surfaces were beautiful. I am using cam, main, and rod bearings from clevite and keith black .040 over pistons and piston rings from sealed power. Unfortunately I couldnt find any rings that would match .060 over pistons so I went with the .040 over ones. I currently am out of money so ill continue in a month or so still need to clean and bore the block and polish the bearing surfaces of it and the crank.

Re: Hybrid swap
Does the block need to go .040" over, or are you just going that big just because?
If the block doesn't need that much to clean it up and you haven't ordered the pistons yet, I would get pistons in the minimum overbore possible, to leave as much meat in the walls as possible and leave room in the future for another rebuild (or more) if needed.
The small amount of potential power gain is not worth the thinner walls needed for large overbores. The gain is very small, if any.

Re: Hybrid swap
1. Swap to a 1227165 TPI ECM PRONTO. There is no tuning support for your existing 1227302.
2. Get rid of that blasted heater crossover pipe running from the thermostat end of the intake under the one runner. You won't be using it and you will probably need to relocate the coolant temp sensor to that hole using a 3/8 NPT tap and plug the other hole. If you plan on running the heater, use a 12 AN to 1/2 NPT adapter fitting in place of that quick connect POS and get a 12 AN 180* elbow to run heater hose to.
3. You NEED an alternator bracket and alternator from a 93-95 and make a custom bracket for the crank sensor. And you will need to modify the alternator rear housing. You're welcome. The ONLY part of the BCC kit worth anything is the damper. But you can make that with your eyes closed. And I hope you have the right crank sensor for a 3.4 93-95.
And are you selling the 2.8 parts? If so, PM me. I'm in need of a couple things.

Re: Hybrid swap
I didn't say it hadn't been hacked. I said there isn't any tuning support. Nobody bothers to work with the 302 because they prefer to swap to either the 1227165 or 1227730 or others which use different definitions and better code ($88 comes to mind). So you may or may not get help due to the fact you're pretty much venturing into unknown territory. You already have pretty much eliminated the use of a Moates Ostrich or the like due to the fact that the 302 doesn't have a MEMCAL.
I'd like to see how this turns out if you do decide to try working with the 302... I already know tuning an MSII is nearly impossible unless you buy it prebuilt because weird problems happen...

An ECM doesn't need to have a MEMCAL in order to use an Ostrich. The '7747 and other C3 type ECMs don't have MEMCALs, and the Ostrich works fine with them, with a socket booster to help increase the signal.
Tuning an MS2 is not impossible with a DIY built unit. The tuning is EXACTLY the same, pre-built or DIY. "weird problems" happen because people don't research or understand what it is they are doing, regardless of who built the MS2.

Re: Hybrid swap
*update
So the block is off to the shop finally to be cleaned, bored, cam bearings installed and to have the rods reconditioned and new pistons installed on them.
Engine stand and picker also showed up and put together and I got a throttle cable.
Side note the radiator support should be fixed within a wewk or two. I also got my hands on an Ice man racing tb my dad found it in a tree when he was doing a job lol dont know what it was doing there I may try to adapt it to the upper intake

Re: Hybrid swap
Sweet let me know how those pushrods fit. If you have different lifters then i did it may be off a bit but i have plenty of sets within what you would need and will trade ya so you have the perfect set.

Re: Hybrid swap
Priming the block
Clear coat on and done
Installing camshaft Delta 270 grind
Not using the 3100 upper and lower but put them on to check out how she'll look cleaning the 3400 upper and lower for paint and primer soon
Got alot done since I last posted waiting on plastigauage and feelers to check oil clearance for crankshaft. Quick question can I use the heads from a 3100 on a 3400 upper and lower. Will they flow the same? I didnt notice when I gought the 3400 heads but some how th guy broke 3 exhaust manifold studs off in the head. Didnt see it cause the manifols were still on them.

Re: Hybrid swap
Are you using 3100 pistons?? Then use 3100/3400 head gaskets. .060 comprested thickness. When I ran Ole felpro gaskets and was over bored I just ran std gaskets.

Re: Hybrid swap
If you are running a 260 cam or larger i would strongly strongly suggest saving up a few bucks and getting these. They are what i run and it will be the last set of springs youll ever need for you ride.
They fit right in there and are direct replaceents for what you already have. you can also reuse your retainers and locks. So if you wanted to you can just replace the springs themselfs and be fine.

Re: Hybrid swap
Engine is 90% built! I still need a few odds and ends like a crank trigger and the oil feed and return for the turbo and some big injectors and a walhbro fuel pump. Then its on to electrical crap like swapping in a 7730 ecm with a MAP sensor wiring in dis ignition and crank trigger sensor!

Re: Hybrid swap
Looking good bud. What are you doing for a crank trigger? Buying a pre fabed one or making something?
C2YT contact him, he may still have some 36lbs injectors for sale. I wouldnt go any smaller then that though but it may save you some cash. If not contact southbay for some 48lbs injectors, they will make you a good deal. 150-200 bucks for a set of 6. I had some for many years then sold them to C2YT.

I actually sold the 36lb injectors Mark, but thanks for the sending him my way!
Contact southbay for sure. I believe you also get a certain percentage off if you say you are from TGO.

Re: Hybrid swap
thats actually pretty cool that they'll offer discounts yeah ill give em a call ill probably get some 50lb injectors instead of 48s its like 300 without the discount and I ordered the crank trigger but I still need a way to mount my alternator and sensor for the trigger

Re: Hybrid swap
Yea its a 10 percent discount from what i remember. 48 or 50 doesnt matter its whatever they have. I dont remember them costing 300 bucks though. I got my 48lbs bocsh type 3s for IIRC 180 give or take. But 2lbs per hr is hard to notice the difference. I can tell you all that those 48lbs/hr injectors will support a hybrid 3.1 or 3.4 up to a easy 450Hp at stock fuel pressure at 15psi of a 1-1 rising rate fuel pressure(stock 3100 3400 regulator).
IIRC 48(lbs/hr) multiply by 6 injectors = 288lbs per hr. Then multiply by the highest duty cycle you want to run. Southbay told me 90% max anymore then that and its basicaly static (wide open) that equals 259.2lbs per hr. Then you divide that by your BSFC(Brake specific fuel consumption) Rule of thumb is .55-.60 for turboed cars, and honestly this is all just a guess compared to read deal times slips, mph, and weight vs duty cycle on a datalog IMO. But 259.2lbs per hr divided by .60 bsfc equals 432 Crank HP.
Now on my car a example pass is this. I ran a 11.23 as a best ever at 123mph. Race weight is 3190 as of that run. My duty cycle was 92% max. So if i use multiply calculators i come up with 487hp when i use 123mph and 3190lbs and 459hp when i use 11.23 as a ET and 3290lbs as a weight.
My point..... is that 48lbs are a very common size. 50s are not so common but if they have them, awsome. Im sure it will work for you and will keep you happy for a while. I wouldnt go any larger then 48lbs or 50, if you dont have to unless you plan to run E85 at some point. I have 80lbs a hr and i will say the bigger you go the harder it is to dial in the lower end of the fueling table exspecially the idle. But dont go any smaller then 42lbs hr either.
Either way you are right where you wana be for fueling. But i will say with those injectors make sure to get a new fuel pump and save the time to change it later when you dont want to. A walbro 255lph or something of that size is a easy swap and will handle what you give to is. I have a 425lph now but for 5 years i ran a 255 and it took everything i could throw at it and worked great. Best 100 bucks ive ever spend on the fuel system.

Re: Hybrid swap
E85 requires much more fuel to produce the same hp level. So if you plan to run 48lbs with gas, plan to run 80s all day for e85. When I ran e85, i averaged about 12mpg. On gas it was 20 on Ave. Keep in mind my set ups a bit wild and has a 3 speed trans. 80lbs injectors got me about 70% injector DC on my set up. 48lbs gas were arround 85%. And on e85 I ran half the boost because my compression was very very high.
this explains it better.

Re: Hybrid swap
I have the injectirs ordered from south bay. The crank teigger came with a mounting bracket so i wont need to fab one. I need to find my oil pan bolts to tighten that on and i need an o2 sensor after that im just waiting on Fasteddie with the headers
