Appeciate all your great starquest content! Having owned a few of both... those 2.0/2.4 are smoother running than 2.6 imo. Luv em, as well as their simplicity I think 93 was year of the 2.4 split... both 6 and 7-bolt. One of my 2.4 is 7 Be very carful choosing fwd DSM driveline bits. Lots of info on truck dohc swap pages Austarion forum have a TON of dohc swapping, covering everything! I mean everything. I'm worried, valuable info may be lost tho Even some 2.4 SOHC staz *monsters*, still on stock 2.4 bottom end! 1st gen DSM 2.0s have excellent low end torque, from stock
Thank you thank you. I appreciate you tuning in. and I agree there is still a lot to learn on these engines, especially using this head, but with a stock bottom end and fresh bearings should take this thing to the next level. I have to keep my eyes open for more parts. Now that disassembling it is completely finished.
I have heard on really high powered applications the wide blocks tend to crack in the cylinder walls, so half filling the block, or for really high hp full fill, the water jacket for added strength is worth looking into. and At 30:00 that bolt is the perfect spot to add a vent hose to go to your catch can it's an old secret DSM mod.
DSM veteran posted on projectzeroG forum way back, that he cracked 3 truck blocks, same spot @ ~450-500hp No problems with any of the car(fwd) 2.4 blocks tho. Says he's built DSMs up to ~800hp A buddy broke his 2.4 crank. Don't know if sourced from hyundai or what. AWD runs mid 6s 1/8th... so, yeah he 'pushes' it
Oh wow that’s crazy Hyundai would be a great option I believe but that’s weird. They do look a little small even though they are forged. I’m definitely going to have to test these out and see if we have the same faith.
@@legionelitemotorsports2096 These are rather relatively "extreme use" cases tho... for a street car at least My buddy never knew the orgin of the failed fwd 2.4 crank. Second one worked fine DSM veteran was obviously "pushing things", for him to crack three truck 2.4 blocks. If you plan hard launching 500 ft-lbs, that sounds like a good recipee, to find weak any links. Both austarion SOHC 2.4 builds I can recall, were 350-450 ft-lbs.... but no drag launches. One starion, one sigma Still makes for a fun street powerplant
The 4g64 has 2mm longer stroke than the g54b of 100mm's as well as having a shorter rod length of 150mm's vs the 166mm's of the G54b. Technically the G54b favors RPM's better than a stock 4g64 SOHC, but because better heads are available, it's got better breathing and therefore better powerbuilding potential at higher RPM's. I've thought about this swap when I had a '91 MM pickup, but that engine was toast and I didn't want to consider all the work involved in making it run again, but I was going to go with the longer sirius rods they offered as well as a slight destroke. I think they offered a 94mm stroke crankshaft that'd bump it down to 2.2/2.3 liters, but better longevity at higher RPM's and not so much side loading of the piston in the cylinders that wears the hell out of the rings, as poor ring sealing and oil consumption killed mine. Just a thought. Idk if the stuff is still available in the aftermarket, but there was a writeup and a website on all of that.
Oh yes, I completely agree. It’s just the computer system on the Starion usually doesn’t allow the engine to rub that high not saying it won’t but because of all of the aftermarket support on the 4G 6 Sirius and all of their engine options, opens up a window that we definitely don’t have in the stock Sterrian community but yes, these engines would be a interesting build due to all of the aftermarket support but I agree, 100%. I’m going to be looking for another card to put this engine in.
@@legionelitemotorsports2096 Hell, I'd love to see it. It's not too hard of a swap by the looks of it, with the only slight challenges being the timing gear and getting the cooling system to clear the firewall, as the DOHC heads would place it mostly directly towards the firewall. I also say timing gear because the deck height is 6mm's taller on the 4g64 blocks so a standard 4g63 timing belt won't work and I can't think exact year and all cars off the top of my head that come with a DOHC head on a 4g64 block. I know it's a Galant, but I don't know what year or trim spec. Maybe that AWD minivan crossover they came out with in the 90's offered a twincam setup too, but idk. It's been so long since I dived into this stuff. I know you got the engine though, so whatever you plan to do is surely going to be interesting at least
