You should really just use the auto light 104's the old copper core plugs because it gives less of a "point" or hotspot in the combustion chamber. Every build is different but this is what I found on my Regal GS

Did GM make a DOHC V6 back in the 90s which used timing chains? I know the 3.4 had a main chain which drove two belts, but any chain ones? I know the 3800 was an OHV.

[@jameslaidler2152]

@@FieroAustin Thanks for the response. Yeah it seemed a decent engine used on a lot of cars. Only it's a main chain driving two belts, says there in the article. Granted, might be less overall strain than a direct to the crank system, but even today the idea of a wet oily rubber belt does not sit well with me. Again, thanks for the info. The modern 3.6 DOHC used 3 chains, similar to VW's VR6 line. If I ever got my hands on a Fiero to swap out, it'd likely be a VR6, I've seen a couple guys on KZbin do it. One guy cut a bit into the rear storage area to modify the exhaust for the "wookie sound" as well as basically vanity plates for the engine cover.

Love the video.....my computer was already performance program...the engine is out and I’m going with a turbo with a 3000 torc converter and 60 pound injectors....it’s hard to find E85 gas so I’m stuck at using 60 pound injectors.....the fuel pressure regulator will probably be just as good as having to have my computer re programmed....the PCM has already the deletes and performance shifting, and the idle and Rev limit disabled. I’m using a modified L67 intake modified with an opening like a series 3.....I’m planing on using the sandwiched intercooler and a external air iintercooler. My trunk is already cut in half....so I might put a cooling fan under the exterior intercooler core and cut a square opening in my deck lid. The turbo is pretty big” this is the reason I bought a 3000stall speed torc converter....might to a 50 shot of nitro oxide to activate on take off. To spool faster. So many choices lol. Ps with a exhaust mounted turbo there’s only 1 space to route the oil return line...it’s one of the most frustrating part of the build...the automatic transmission blocks everything.

pump gas is just fine. 87 octane. If you want more power and modify the engine appropriately (by increasing boost), you might want higher octane for higher knock resistance. 91 is everywhere and 93 is also around.

Thanks mate great video by the way I have an idling surge it holds its rev but if I’m of the throttle it will surge at idle can you help I’ve changed all vacuum lines ignition leads and plugs are new Thanks

[@FieroAustin]

First check out your O2 sensors (make sure the front is OK and the rear is deleted from PCM or has a dummy). Check to make sure your MAP is plugged in correctly. Same with MAF and IAT. Then check your idle air control valve and then boost bypass control valve (could try unplugging it). See if there are any engine codes. Also have your tune checked by a professional. Do you have a custom camshaft? That can cause strange idling if the PCM has not been programmed properly

Just wondering off topic can the stock 2.8 L-44 be rebuilt to deliver 190 HP and still run the stock ECM module. What you doing here is great but it is beyond my skill level.

[@FieroAustin]

I am not sure I can give you a perfectly accurate answer, but my gut says no. If you want more power out of a non-forced induction naturally aspirated motor, you will have to increase torque or RPM or both. Easiest way to gain power on small engines is increase RPM, but your PCM/intake/fueling would have to be heavily modified to support that (near impossible being 80s burn-in transistor tech). Instead, you can increase torque by increasing bore size or stroke, or significantly modifying how the air flows through engine in general. That will be very expensive to do on a 2.8. It comes factory with an 89mm bore x 76mm stroke. The easiest option I would say for you is get a 60° 3.4L L32 (NOT the 3800 or the DOHC) engine. It comes factory with a 92mm bore x 84mm stroke (different crankshaft). They came in 1993-1995 camaros and firebirds. It is pretty much the same engine, just bored larger, and is rumored to be a direct swap. Supposedly you can use all the same brackets, sensors, transmission bolt patterns, and wiring harness. Keep the computer/harness/sensors that came with it. It has a larger bore and thus more torque, and thus more power coming in around 160hp factory. You can slightly modify a 3.4, but honestly a 3800sc is the way to go if you want to put any time into it. Check out the 60° engine family tree here, and look for the 1993 3.4L RWD Pushrod motor compared with the 1985 or 1988 2.8L FWD motors. www.60degreev6.com/vb5/60V6FamilyTree Honestly I think you're wasting your time to pick up 20-30hp with these old 60° engines. I have a very thorough step-by-step guide for both an easy and an advanced 3800sc engine swap here. I think it would be an equal amount of work and money, and you would end up with 230-280hp at a minimum. www.fiero.nl/forum/Forum2/HTML/139530.html

Where did you get the metal vacuum connector on top of supercharger ?

[@FieroAustin]

Haha it's not metal, just spray painted silver.

[@theSaxman5]

One of these days!!!!!!!!!!

[@FieroAustin]

lol hit me up when that day comes!!

[@theSaxman5]

You bet Brother.

[@guitarguymi]

Bro better watch your back. Captin Planet is gonna kick your ass. Lol.

[@FieroAustin]

lol best comment i've had right here

[@Friedbrain11]

3800 is nothing but a slightly modified 3.8L Buick v6....same as the Grand National used and thousands of other GM cars used. It is just as rebuildable as any other engine. If someone has problem with lower end it is because they did not do it right. Ring gap should stay stock for up to 400hp and not be a problem. By the way...this engine is not good for much above 6k rpm. When you start going over that too far you need to get it professionally built. Indy cars running this engine generally failed above 9k and even at 8.5k rpm were only reliable enough to barely get to end of race.

[@FieroAustin]

Thanks for the info! I didn't want to go into the history of the engine much

[@Matt_Lanzer_13]

Robert Clark that’s false though.... the 3800 is different to the 109 3.8 found in the grand nationals and t types

[@Friedbrain11]

@@Matt_Lanzer_13 Actually i am quite correct and as i said it is a modified 3.8L Buick V6 in reality. Don't know how old you are, but i remember when the 3800 came out and the specs and story behind it. I was extremely interested in the engine because of its foundation being one of my favorite engines.

[@Matt_Lanzer_13]

Robert Clark all I’m saying is, it uses no parts from the 3800 found in the grand national. The engine was completely redesigned. Hell anyone can figure that out, it’s readily available info on the internet. The only thing it shares with the GN motor is the displacement lol

[@SwnkyTiger]

@@Matt_Lanzer_13 But Matt if Robert acknowledged that, well then he wouldn't be able to tell you how much he knows and that you clearly couldn't know as much. He is quite correct if you consider any Buick V6 with the same displacement a "modified" LD5 and not a redesign, progression, evolution (pick your synonym).

Clean spark is always needed for maximum compression with maximum air intake, if you ain't got the mixture lined up just right you ain't getting maximum horsepower, ever run a car on file plugs.

[@FieroAustin]

Thanks for the tip

[@brianpaulson7215]

You spent some time and money to get better airflow. Such as porting your heads, having larger valves, N* TB ect. Doing those steps in a NA engine will provide more air and thus more power. But with a SC engine can this also accomplished by getting a smaller pully? I am not saying that (all things equal) that what you did would be worse, actually slightly better. But the cost and time to accomplish almost the same thing (more air) can be done with a smaller pulley if I understand it correctly.

[@FieroAustin]

You are right, a blower is the best source of cheap power. Without intercooling or running E85, you would be lucky to make more power under a 3.4" pulley. However I got my heads ported for $200, the N* TB/LQ4 MAF for $25, and the larger valves came with my heads. Junkyards are great. Stock heads will outflow an M90 according to intense, but it certainly can't hurt.

[@charleswittmer2477]

the smaller ports and valves will cause higher temperatures because of their restriction which will require a more docile tune so the bigger valves and ports will help higher rpms but the smaller ports and valves help the lower rpm range which actually is where the motor will spend most of it's time in a street car life.

[@johnrusac6894]

You should never replace your tires, as they all will eventually go bad over time.

[@FieroAustin]

they were dang bad already :)

[@anthonymacaluso1488]

Wish I could barrow you for a week when I swap my engine

[@FieroAustin]

haha.. just gotta mess up a few times and you'll be good!!
