So I picked up a used 2300 2 barrel and trying to test it on a 3.5 litre 911 engine with some meaty cams. Using a similar looking collector box/manifold like yours. But for some reason, it is just a pig to get to run and stay running. I'm using the stock CDI ignittion system and feeding the tachout output from the 14 pin connector to the holley. Does it need anything else or should it 'just work'?
Fuel pressure is key. Make sure you have a gauge and it is spot on. Holley is sensitive to coil and ignition I run a 123 ignition and coil. Also how did you plumb the temp sensor. You got to run it off oil temp and finally make sure the 02 sensor is in spec and proper distance. It should run if you put in the proper data to the little computer (cubic inches etc…)
@@911engineguy Check the electrical connections Holley is very specific, and if you call them, they will ask you about your splices.... if they are not really solid, it does its own thing.. Sounds like you are getting there... go back through their instructions and check each step. Verify the fuel pressure, don't rely on the old "CIS pump should be good". Timing is obviously important; computer setup; return line setup; electrical.. AIR LEAKS.... did I mention AIR leaks?? they are a killer to the setup and Porsche's "amazing" design of intake runners etc can allow air in and that will throw it all off. Start it and spray with water / soap or the chemical of your choosing (propane etc..) and see if you are leaking. I had this happen and I chased it for some time.. my mounting nuts had vibrated loose and air was entering...this falls into the "ask me how I know"... Before you think it is the Sniper, double check it all and then check it again.
You would have to do the homework on that application. Custom manifold and this would be the only option, and it supports up to 350 HP which still may flow too much... www.holley.com/products/fuel_systems/fuel_injection/sniper_efi/sniper_1-_and_2-barrel_systems/sniper_efi_2gc/parts/550-866
I use pilkington spray foam glass cleaner I've also used wd40 but the honest to god most important thing is to make sure you've got a clean surface around the pinch weld and keep it wet and slick it literally takes about 10 min when your going back with new rubber always lay it out in sun or winter job leave it in the heat all night before the job cause the new rubbers can be a mf lol specially when you got that zipper with the chrome oh my God
Actually ran good, pulled good, amazing little setup. I did have a backfire and no pop off valve so I am sourcing a new CIS airbox to remake it. I manufactured and designed a mounting plate for the 4 barrel patter to mate to the CIS airbox. While it is being re-done, I am running my triple webers. Gas mileage was way better too.
Wow, great! I'm going to try that. How do you tell the Holley software what the motor's temperature is? I know it normally needs a coolant temperature sensor. Did you just opt for the oil temperature instead?
@@r.arabian3056 have you driven it down the road yet? I did a sniper on a range rover and it worked great but it was a much more normal application. I've got a cis 911 and would love to ditch it for efi. I've heard atomization could be a problem with a center mounted carb which may make slow speeds difficult/rough
@@BUILTOFFICIAL yes. It works. Look up Mike Kiamy on you tube. he built one with Solex cams... a complete screamer. Sold on BAT more than 100K last year. The throttle response is amazing. No atomization issues I can tell. That is all old VW based info... it works.
I used Dove dish soap and some water before and noted other RU-vid rubber seal installers suggested dish soap as well. I have a six inch chop top 69 Mustang Fastback restomod I will be trying to install smoked rear glass tomorrow. Since 1979 when it was chopped I used tinted Lexan with opening and removable from side to side split window but this time it's going back to glass. Even WD 40 is recommended by the WD 40 corporation which I do have on hand, I look forward to it, 'never do today what one may possibly do better tomorrow' I always say.
You don't want to know.... but in 2006 dollars when pro shops (renegade and others) did it, I have a book with 60K in receipts, not including the car. There is alot to the car not shown in the video.... it is pretty custom.
The vacuum can on your distributor is 90deg different from mine. But the No1 spark plug line looks in the same position. So I am curious, what distributor part number do you have?
I'd have to pull it to get to it.... I don't think I can get a photo of it. But it is the original, stock 1971 fuel injection distributor. Make sure where your vacuum can is, you can twist the distributor. If you are not in the same spot, ie toward the opposite side, it is 180 degrees off... you can't twist enough for timing possibly. All depends on the timing of the motor though so don't just pull it. The position it is in allows for a wide range of timing adjustment turn (not that you need huge swings). I'll take a look later today and see if I can get the dizzy number.
Ha, I was being stupid. You just have your No1 plug going to a different cap position, duh :) But I am curious what distributor model you have because it seems you have the dual vacuum and few people seem to like that. I have dual weber carb IDFs so a different setup, but am also running a dual vacuum distributor JFUDX4 (or a model 205) with electronic module inside.
Hi Joe. Absolutely. My tuner is "Yimisport" in Santa Clarita, CA. When we discussed numbers, he could have bumped this to in the 350 HP range, but we felt that would be alot, and we would have trouble with the torque number. Torque is what will kill it. So we tuned it at 300 HP on the nose, and 250 Torque. IT is also set up so that the power doesn't hit like a 2 stroke, but increases as the car is already rolling so it transfers power smoothly but very raw. In this video, it was still only at 225 hp using a stock air to air subaru intercooler. I upgraded it to air to water and thats how we made power. STI turbo and STI injectors with Cobb software. It runs REAL fast now....
@@r.arabian3056 oh of course, I wish I had 100hp 😂😂. It's just that people that own subarus brag about their cars having 500 hp, so I had the wrong idea
@@ozkrpalminteri9431 So yes they CAN. My tuner said stock, he can push it above 350 HP. But on this car, the 901 transmission will blow up real quick with that HP number and the associated torque. This car is 300 hp with 249 torque, which wont kill it. I would have to upgrade to a subaru trans to go above what it has. A 500 HP car would need all forged internals for sure. That being said, power to weight on this car, it keeps up with modern 911's easily. It is only money....
Sadly from 2030 on all combustion cars including classics will be banned from public streets in entire EU and Scandinavia :-( In Germany the Green Peoples Party gave order to shorten fuel supply from 2025 on by reducing petrol stations to only one state operated central gas station per city. From 2027 on in the EU certain car spare parts will be banned too....as exhaust systems, turbo chargers and even some engine and gearbox oils...California and New York will do the same from 2027 on.... So no investments should be done in oil burning vehicles any more....:-((
Well we get to enjoy them till they ban them, but I think gasoline isnt going anywhere really. All this electrical horseshit isnt going to take over until they perfect it, and that battery tech is years away. Drive em like you stole em!
This one has what I believe is a "Mad Dog" motorsports type mount... it swivels so you can do certain maintenance without a full engine drop... like a clutch change. Not the "factory 6 mount"... Clears easy, just one area on the CIS fuel distributor had to be notched like 2 inch by 1 inch to allow for it to fit without any hitting. But under the deckled, not a problem. Top fits in trunk, no cutting required.
Sorry you feel that way Hans. One of us works in a high risk environment and may have been exposed at the time this video was made. We were just being cautious as other family members are high risk as well. Politics aside, its about cars buddy.
Sadly soon all combustion cars and trucks including classics will be banned from public streets in entire EU and Scandinavia :-( In Germany the Green Peoples Party gave order to shorten fuel supply from 2025 on by reducing all conventional fuel stations to only one state operated central gas station per city or county. Car washs will be forbidden too because they are climate killers, now they want to slow down all the gas station pumps from 20 litre per minute to 2 litre per minute...From 2027 on in the EU certain car spare parts will be banned too....as exhaust systems, turbo chargers and even some engine and gearbox oils...California and New York will do the same from 2027 on.... So no investments should be done in oil burning cars any longer....They even created a new kind of crime here, called emissions and smoke crime.!!! (BABVVEN & TEBBVEN & BEFVO laws)!!!!!!
I used to have the WRX engine, and now have the LS3 with a hot cam. I'm almost thinking of going back to the subie engine. What is the biggest subie engine that can be put in there with a turbo?
A six cylinder Subaru is fun- but none of them have the aftermarket support that the EJ series does. An EJ205( 2.0wrx) stroked with a 2.5(STI)crank makes a really lovely, torquey bottom end for the street. An EJ257(2.5 STI) destroked with the 2.0 crank is the move for high HP, high RPM applications.
Keeping the 901 trans really changes the usual response from the WRX engine and Subie trans. Gives it long legs and real chance for the turbo to unwind. Great chassis changes really make this a fun car for the driver and the passenger! Ask me how I know...
good job guys. always start with bottom pinch weld. set the bottom rubber lip over punch weld and begin pulling it over with a hook tool then begin working it in. Also wd-40 works great . just spray in the rubber channel
Winner Winner Chicken Dinner Dave! Yes. When I got it from him it was at about 225 HP. I have now bumped it up substantially to 300 HP with an water to air intercooler. I think Tom would be proud. He is a nice guy. Torque is about the same to save the 901. At WOT it pumps 22 lbs of boost now.
That's so cool and much more interesting than some LS V8 conversion. Are there kits available for that conversion or did you have to fabricate everything?
amazing, love the car! you nearly kept up with that lambo there. 914 is def in my top ten cars of all time, so much character, super symmetrical, i love the design
He just sold his on BAT this year. It wasn't much to look at and because it was his, it got some decent money. It wasn't a bad car, just rough around the edges as Magnus is...
