Supreme Cutlass Posted September 24, 2005 Report Share Posted September 24, 2005 All of this for 5 horsepower? Kind of an asshole response.... but it is a good point. I think you might be a bit dissapointed is all. Quote Link to comment Share on other sites More sharing options...
coolguyian822 Posted September 24, 2005 Author Report Share Posted September 24, 2005 well i still didnt get an answer on the questing standing lol, the reason why i want to put the 3,5 in is because its a light engine and its cheap to buy. the 3.8 sc is a nice engine but it cost alot here to buy, and anyone i find under 1000 have like 180km on it. and also the SC engine needs premium fuel and at the price these days its alot, The big reason is i love the sound of a DOHC and the High Red Line :-) Anyways, if anyone knows how to install one please let me know, if for any reason you dont think this swap is not a good idea keep it to your self, i could care less,. :-) take care Quote Link to comment Share on other sites More sharing options...
NOHC_WBody Posted September 24, 2005 Report Share Posted September 24, 2005 All of this for 5 horsepower? I'm in agreement with the mountain man here. Save your money & actually upgrade, instead of sliding sideways to another boat anchor with no aftermarket support. Quote Link to comment Share on other sites More sharing options...
cutlassdude96 Posted September 25, 2005 Report Share Posted September 25, 2005 it will not fit in the gen 1 W's its to wide 3.4 60*, 3.5 90* and it needs the 65E tranny Quote Link to comment Share on other sites More sharing options...
THe_DeTAiL3R Posted September 25, 2005 Report Share Posted September 25, 2005 The new 3500 3.5L would be better. Those things have good power, moves the 2006 Impala pretty good and spins the tires on SV6 minivan like a motherfucker! Quote Link to comment Share on other sites More sharing options...

It sounds better than the 3.5 S*, is MUCh cheaper, takes the same gas, has a higher redline (I believe S* only goes to 6500), and there is no reason to upgrade. You won't notice a difference between the 3.5 and 3.4, except that you'll be bankrupt after the 3.5 swap, and that's if you ever get it running right. Spend your $3000 in a turbo.

TeeJay3800 Posted September 25, 2005 Report Share Posted September 25, 2005 I have no info on the swap, but I can personally atest to how nice the 3.5 is. It moves my parent's Aurora very well, and is the smoothest motor I've ever experienced (despite that fact its a 90 V6). True, you only gain 5 HP, but you gain at least 15 lb ft of TQ over the latest and greatest 3.4. Not a lot, but my only point is that the 3.5 is a great motor.

Aaron Posted September 25, 2005 Report Share Posted September 25, 2005 He is right, its a great motor far more advanced than the 3.4, but the 3 grand (minimum) is better spent elseware. Its just not smart to do such a complex swap for 5hp, virtually no gain in gas mileage, the only real advantage being its advancement in technology, which makes the swap that much harder. And if none of you have felt a PERFECT running 3.4 DOHC, I invite you to my house. I have honestly never felt a motor so smooth as the crate engine in our red Z34. It is so smooth that I'm constantly checking the tach to make sure it's running! The 3.4 can be EXTREMELY smooth, just at this point in time, few are. I'd personally rather have a N*. Just as smooth, still lighter than a 3.4, and you're starting with 275-300hp. Quote Link to comment Share on other sites More sharing options...
digitaloutsider Posted September 25, 2005 Report Share Posted September 25, 2005 I really need to figure out how all this timing stuff works. I know the 3.4 in my Cutlass is so far off it's not even funny.. Quote Link to comment Share on other sites More sharing options...
fastbird232 Posted September 25, 2005 Report Share Posted September 25, 2005 You know, it's hard for us to only give you *positive* advice about this swap because there aren't many positive things to say. You want to spend thousands of dollars to stuff a 3.5 under the hood, fine. You'll gain a couple of horses and have a one-of-a-kind GT on your hands. The smarter move, however, would be to spend that money on a turbo like Aaron said. That way, not only will you still have a unique GT, you'll also have the fastest goddamn sedan on the block. And then you can post pictures and make the rest of us jealous. Quote Link to comment Share on other sites More sharing options...
GnatGoSplat Posted September 26, 2005 Report Share Posted September 26, 2005 it will not fit in the gen 1 W's its to wide 3.4 60*, 3.5 90* and it needs the 65E tranny Don't ignore the cutlassdude. He is right, the 3.5 DOHC will require firewall and dash modification to fit. Very much not worth it considering there are equivelent, if not better engines that will fit. It's also not as light as you might think. An aluminum DOHC engine weighs about as much as an iron pushrod engine. The heads are nothing short of massive. That's a whole lot of aluminum and a whole lot of weight. Quote Link to comment Share on other sites More sharing options...
OldSkoolGP Posted September 26, 2005 Report Share Posted September 26, 2005 Look at is this way. A 95 3.4 DOHC makes 210HP. If you got only Ben's OBD 1.5 chip from the 60degree store, you would easily surpass the 215 that the 3.5 makes stock. It's in interesting idea to be sure, I wouldn't mind seeing the results, but IMO, dollar for dollar, if you're doing a buildup on a budget, stick with what you got. There's no reason a 3.4 can't run low 14s without forced induction. I already know of one, it's just no one knows about him. 94 3.4 setup in a 91 SE, automatic, rebuild with some ported components, ran 14.1. Then he sold the car. Still can't figure that one out.

Thats's a good point cuz my dad's 3.5 looks HUGE, but it doesn't really make any sense because the 3.5 was used in the Intrigue, which of course is a W-body. Why would the 3.5 fit in one W, but not another? Quote Link to comment Share on other sites More sharing options...

Why would the 3.5 fit in one W, but not another? 2nd gen W's are completely different. They were a ground-up redesign loosely based on the 1st gen. Just take a look at the front suspension, no similarities and no interchangeable parts. Quote Link to comment Share on other sites More sharing options...

manitcor Posted September 28, 2005 Report Share Posted September 28, 2005 on top of all that L67 swaps can be done for less than 3 grand, many montes have done the swap for even 2 grand. 3500 would be a good idea but I cant even find a top end for less thant $350 - $500 still since its so new. turboing the Lq1 has been done and proven to work well, though youll need the trans upgrades to support it. swapping in the 3400 is also an option, very cheap (less than $1000), but you loose power, what you loose in power you gain in easier maintance. $1500-$2000 into the top end and you can be putting down close to or over 250hp. If $3000 is the amount of money your working with theres alot more you can do with it than get 5 ponies. Quote Link to comment Share on other sites More sharing options...
sonyman87 Posted September 28, 2005 Report Share Posted September 28, 2005 how about swaping in an Iron Duke if your conserned about gas. or a 3100. <-- probably alot easier. 30+mpg Quote Link to comment Share on other sites More sharing options...
