Re: engine swap question

Maybe i'm being tooo technical about this, but thats just how I see it.
Anyway off that subject, how's it cheaper Branden??

Re: engine swap question

like I said before, SBC parts are so common they might as well have put them in every car. other guys have done the swap before so you don't have to waste your time figuring out the odd stuff for the swap. you can find any new SS or f-body at a junkyard and score a LS1 for pretty cheap. lots of guys here are doing the swap, me on the other hand just kinda want to stay tru to the roots of the truck AWD/4spdAuto/Turbo and intercooled V-6, you can throw any combo in there and its still a SyTy.

Re: engine swap question

So a 3.8 swap is also more cost effective to build than a 4.3? The parts are more readily available?
Does the 3.8 use any similiar parts to a 4.3 or 5.7, that motor is foreign to me?

aftermarket is alot larger, more people know the motor and can work on it, same goes for tuning, and it's stronger then our motors right from go strength wise

Besides.. the first proto type sy had the buick gn motor in it.

I meant if you change alot of other aspects of the truck tranny, I/C, and others how can you justify that you should stay turbo V-6 because it came that way from the factory, when the other parts hadn't. I agree with your new statements and that is also why I love these trucks and SUV's.

It's called aftermarket.. when people upgrade there turbos and ic setups on there svo mustangs, dsm's, turbo dodges you name it they are still concidered what they are right?

What would it matter if you don't have the factory 700r in your truck as long as it's turbocharged, awd and v6 it's still all that a syty was ever said to be.. and waht they are known for but if you want to swap out the motor for a v8 go right ahead.. I may not agree with it but it's your truck/$$

If we go go back to the beginning the intial question was how is a V-8 cheaper than a V-6? I still stand behind this question, simply because you have no motor to purchase to begin with, you already have the V-6.

You could always sell your v6 turbo motor first and throw that cash towards a small block v8.. also cheaper would relate to repairs and tuning.. Everyone knows how to work on v8 motors for the most part and eveyrthing's been done.. no guess work, no one off fab jobs, and yes because more people are using them and the aftermarket is a billion times larger then the 4.3 crowd.. tuning would be that much cheaper and easier to aquire. Hell you could yank all the computer crap, injector crap and stick a carb on top and fiddle with the jets for a few runs and be done with it. Of course this is all my opinion.

Re: engine swap question

actually if we go all the way back to the original question it was whether or not the ecm could drive another pair of injectors to run a v8

Re: engine swap question

well it's a budget thing and a do it different thing. as far as power, well that number is always more than i got now. the headers i found are actually twin turbo headers. and yeah i thought about the 3.8 swap and it has merits too but it all is just boiling down to i'm really interested by the idea of doing it w/ an 8. that doesn't mean i'm gonna hack the truck to make it fit. and truthfully this idea might change, but what's the difference as far as me using a 8 to do it and someone taking a bowtie 4.3 w/ an oddfire crank and pontic heads w/ a different intake and different fuel injection system, different intercooler, different transmission and so on and so forth? but i have found a good rolling (non ty) body and i might just buy it and build the engine for that.

For a bowtie-odd fire-pontiac heads, it would be cheaper to do a Turbo LS1/6. If your going to stick in a run of the mill Naturally Aspirated SBC or stroker SBC, the 4.3 is a better idea.

Yes, DIY tuners often use stock 749 on boosted V8 applications.

Re: engine swap question

I think its also a matter of just how fast you really wanna go. there are quite a few sytys making over 500hp at the crank with v6 turbo setups still. Mine still is the stock block, thats about it, and its already gone WAY faster than im allowed by the nhra rule book. 500hp is one thing, 1000hp is another. Also, how streetable is that power, and how hard is it on parts. 1000hp v6 is awesome. its expensive and not exactly street friendly. race gas isnt bought on every corner. there are now countless ls1 style cars turbo'd making over 800hp at the wheels on pump gas, and the cost of their engine build is considerably less than a v6.

I did some hard thinking before i abandoned my bowtie v6 project to go with the lsX style v8. to build a high hp v6 or to build a high hp v8? costs less for v8. it will still have a syclone vin number whether its a v6 v8 v10 v12 or jet turbine powered. i am also not quite as much of a "purist" as some which is good because i will hopefully be able to sell all my v6 stuff and regain the out of pocket for building this v8. each person is different, so each truck will be different, might as well enjoy all of them and seeing all the different cool combinations there can be.

i have no interest in running an n/a motor in the truck.

Re: engine swap question

everybody should make the dissision on his onw, either stick with a v6 or go with a V8.
it has been proven numerous times that V6's can be fast, just the basic 4bolt main, 422 cam and vortec heads combo, bigger turbo and injectors.
yes that stuff is expensive, but a turbo application is just more expensive.
if you count everylittle penny doing a v8 swap, i think in the end it will cost the same money as a v8 swap with a turbo.

altough i underdstand the people doing a ls1 swap, cause they are fed up with parts breaking inside the engine, but there are plenty of people that have bad luck, i had to take the engine out 3 times, not because things were breaking, but because it was build by somebody with lack of skills.
if you do that to a v8 it will destroy itselve also.

Re: engine swap question

I kind of like our V8, although a turbo or supercharger may be in order someday. Explaining why a Syclone has a V8 can get a little old, but it has its perks. Changing sparkplugs is a breeze, as well as having acres of space in the engine bay to access stuff. Sure, at times I still wish we had the stock engine, but having an oddball can be fun too:2cents:

Re: engine swap question

Not having to deal with cap and rotor issues is reason enough to switch to an LS1 V8.

My estimated cost to build the V6 motor, just the longblcok here now (no bolt ons), was ~$8500. I can get a built LS1 shortblock for $3500 and a decent set of heads for $1000.

I don't have time to list every reason out right now, but it is MUCH cheaper to run an LS1. Also some mentioned weight of a V8, remember the stock motor is iron block & heads, LS1 is all aluminum w/composite intake as well.
