AGE_ Posted February 24, 2003 Report Posted February 24, 2003 i'm wanting to put one on my 93 GTP, but i just can;t seem to find anyone who makes one for it, can anyone help me out :?: Quote
Robby1870 Posted February 24, 2003 Report Posted February 24, 2003 Sorry man, nothing out there. There's not a lot of stuff available for the 3.4L DOHC. Your best bet, although it will be VERY difficult and COMPLETELY custom, is for a turbo. Just go with the usual, bolt on stuff for now and you should have a pretty quick car. OR......L67 swaps are very popular..... Robby Quote
lolumz34 Posted February 24, 2003 Report Posted February 24, 2003 http://www.rsmracing.com has one made...e-mail them about it Quote
Intlcutlass Posted February 24, 2003 Report Posted February 24, 2003 an L67 is a 3800 II with supercharger. 240 hp. I know our moderator knows this, but the new guy might not. Quote
Redfox340 Posted February 24, 2003 Report Posted February 24, 2003 www.rsmracing.com has one made...e-mail them about it Lolumz34, Wasn't that just for the 2.8L / 3.1L / 3100 SFI and the 3400 SFI? And I just checked... If the 3.4L DOHC supercharger is out, CRAP! Why didn't anybody tell me? I'm all over that then if RSM released it... :!: Hopefully RedZMonte will read this and invite me to do a turbocharger project instead on the Cutlass... what do you think RedZ? (tanget) How's the Monte Carlo coming along? Haven't heard from much about your current status. :!: - RedFox340 Quote
Robby1870 Posted February 24, 2003 Report Posted February 24, 2003 I checked RSM before making that post and they did not have one for the 3.4L DOHC. They did have it for 2.8/3.1/3100. Robby P.S. Sorry about not explaining the L67, its just a habit........ Quote
AGE_ Posted February 24, 2003 Author Report Posted February 24, 2003 I have email RSM and am waiting a releply, and my search still goes on for a supercharger for my 3.4 dohc, Age_ Quote
LukeZ34 Posted February 24, 2003 Report Posted February 24, 2003 RSM used to offer the supercharger for the DOHC.. and it was always 'scheduled for release'... but actually never did get released. They were waiting on someone to order it so they could complete the kit.. Even if you do have it, your gonna get raped for price. I'd wait for someone in the DOHC community to successfully turbo their 3.4, as I'm sure it's not too far around the corner. Quote
91GranSport Posted February 25, 2003 Report Posted February 25, 2003 How reliable is the 3.4L Twin Cam itself? I heard horror stories about that engine. I know the usual problems that go like the alternator and such, but I don't consider that an actual part of the engine itself. I know that since it has more moving pieces than a 3800 Series II, there are more things that are prone to failure. However, I'd like to know how reliable the engine is on it's own, and how strong it actually is. After all, bolting on a turbo kit on the 3.4L Twin Cam would definitely put quite a bit of stress on it. Quote

After all, bolting on a turbo kit on the 3.4L Twin Cam would definitely put quite a bit of stress on it. GranSport, The DOHC is as reliable as long as you know the service intervals... it's as easy as that. Since it's the same block as the 3.1L, the bottom internals are nearly identical; the DOHC has more 'accessories' on the top side of the motor with the valvetrain and intake design. When I bought the Cutlass two years ago, I thought it was just another engine like my push-rod 2.8L V6 Beretta. WRONG! Some of the biggest overlooked items on the DOHC are the secondary timing belt, intake manifold gasket, power steering pump and the oil drive pump assembly o-ring. The kevlar timing belt lasts just a tad longer than a serpentine belt, but not by much. If the timing belt snaps while the car is running you could possibly bend a valve (engines 1991 - 1994) and surely snap / ruin the entire valvetrain (late model 1994+). Many snap due to age, and other rot from a leaking power steering pump. Watch levels on fluids and keep a clean engine bay... The o-ring is just plain age. After hot roddin' the DOHC so many times, you'll find yourself placing newspapers and tin pans underneath the car to collect the oil. Very deep repair, but not much of a part. Couple dollars invested in a new ring and some high temp RTV silicone will get you back on the road in no time. As for the intake gasket, that's been a GM recall for years. The expanding of metals and heat transfer basically dry out and crack the gasket, letting in un-filtered air produced high idle RPM's while in Park, Neutral, and in gear (compared to "power braking" a vehicle). Otherwise, I'm happy. It's been a great learning experience for me and I wouldn't give it up just yet. Maybe a few alternators and hot temp days I'll change my mind! Nah! Want to try to superchrager / turbocharge it first before I get rid of it; I'm an engineer at school. I need to take advantage of the MIL! - RedFox340 Quote

LukeZ34 Posted February 25, 2003 Report Posted February 25, 2003 I'm curious as to how many they have sold, and if it's even been tested at all. That's a lotta damn money too.. sheesh. Quote
lolumz34 Posted February 25, 2003 Report Posted February 25, 2003 When I asked him before...they said that they had not installed any. There was noone that wanted them... Quote
Redfox340 Posted February 26, 2003 Report Posted February 26, 2003 What about a free 30-Day trial? :shock: Anyone want to subject themselves to testing? I would if I was up there! 8) Just my $0.02 though... - RedFox340 Quote
lolumz34 Posted February 26, 2003 Report Posted February 26, 2003 I would love to test... I'm 45 minutes from there. But...I don't want to have to pay the money after Quote
Robby1870 Posted February 26, 2003 Report Posted February 26, 2003 $4900 is way too much money, IMO Robby Quote
patgizz Posted February 26, 2003 Report Posted February 26, 2003 i have a feeling nobody wants to justify a $5000 investment into their $2000 w-body Quote
lolumz34 Posted February 26, 2003 Report Posted February 26, 2003 Well...if I had the money... I would love to have a gramma car that everyone looks down on...then at the lights...there is nothing but dust... And to do that with everyone...hee hee Quote
Robby1870 Posted February 26, 2003 Report Posted February 26, 2003 yeah that would be a priceless feeling man. Thats what mine will be, eventually. Robby Quote
ctx46 Posted February 26, 2003 Report Posted February 26, 2003 supercharger meets Mr. LQ1, allot of fun...... and then..... the slushbox blows up nascar style spilling its cherry flavored slushie on the pavement, and mysterous metalic gear looking chunks appear out of no-where...... us LQ1's have enoughf troubles with the tranz blowign out because of out crazy revving capibilitys, not to mention the extra 100 hp at the tip of your toe's...... It would be cool and all, but to much money, and to much shit would break in the prosses..... just my 2 cents.. later Joe Quote
GrandPrix34 Posted February 26, 2003 Report Posted February 26, 2003 NAH~~ you just jealous you dont have one for you since your MAF and im MAP and RSM doesnt make a S/C for you Quote
ctx46 Posted February 26, 2003 Report Posted February 26, 2003 and your sol on your last statement...... with a GM tech II scanner, a little know how, and about 10 min i can make my car ignore the MAF, and be a map system.... Im not concirned with that aspect of it....... Later Joe Quote
