v8 swap

[3kgt2nv]

is there anyone that has swapped a v8 into a dsm yet or is the bay just too small for the swap. tried searching but all i could pull up results were for 6bolt swaps.

i know there are some v6 swaps

please don't...... we want to be less like the muscle head retards and more like tuners. We don't want more cocky v8 guys running around, but if that's what you wanna do..... go hard. my 2 cents
sorry if I offend anyone with my thoughts on the matter.

Thier is a new one starting in the builds.

anyone can be a blowhard, its the personality not the type of car... but i agree... why put a v8 in a tuner car? seems like youre takin the easy way out

Realy that easy done a million times. The easy way is moding what you have. Why because its already been done. Think about it.

I mean make it v8 and RWD and I would be jelly as can be. Go ahead and set it up for drifting just to put the cherry on it if you would please.

you have a point there it would be sick. but my point is the hp/torque out put to cylinder ratio, the old 350's with the 4 barrel carbs only put out around 180 hp yet the 4g63 with half the cylinders puts out only 45 less hp. So in that regard your making a very illogical decision and the smarter choice would be the 4g63. But in the regard of an LS1 ya it would be a different story, its all about your hp/torque to cylinder ratio, and dont forget the weight difference between the two engines!!

Example I have an 84 supra with the n/t inline 6 that puts out roughly 160hp and 163ft pounds torque while the 4g63 n/t puts out 135hp with 136ft pound torque. With the 5M-GE (supra) weighing in at 170 pound more of engine and only 20hp gain the 4g63 would be the better choice. I know a local dsm'er that did the swap in the same supra I have and it was awesome! he put the turbo'd 4g63 in though so the car lost weight and gained an extra 30hp.

first off a 350 making 180hp is a early 80s engine.

the same 350 from the early 70s would make 300-325 hp and close to 400 torque

the reason i ask is i have a high compression 427 from a 68 vette that makes 395hp and 405 torque stock tht i am trying to decide what to do with it.

plus nothing sounds like a v8.

i am still finishing my 4g63 talon just wanted to know if there was a v8 swap build thread to show what all was involved

If you have a 427 corvette engine than sell it for 5k+ and mod the shit out of your car. You are talking 15-20K+ in fabrication to install a big block and installing a solid rear end. If you want to put a big block in something than buy a car that is already rear wheel drive such as a 240, rx7, mkIII supra, a fox body, a camaro or something along those lines.

its only 15-20k if you cant do the fabrication yourself. and to me the engine is out of one of my old cars so why sell it when i can use it for a project.

as far as buying a rwd car to put it in. i guess once again because there is fab work i should give up and just do the easy thing that everyone else does. you do know there are plenty of rwd converted cars out there not just dsm wise but for all kinds of platforms that started out fwd or awd.

i guess i should just sell my dsm since modding and restoring that has had fabrication work and isnt always easy.

thanks for pointing out the flaws in my idea. i guess im going to part my car out now

I am well aware that there are plenty of these kind of conversions out there. The way that i look at these kind of questions is that if you have to ask someone else if it can be done than you are in no way able to fabricate it yourself. IF you want to be the different guy with the big block dsm than go ahead, BUT there is a reason why these cars are so special and it isn't the the body. It is the 4g63. The stock block 6 bolt will handle more power than just about any stock block v8 that you will find. IT is what makes these cars what they are.

i am more than able to but i wanted to see what are the major issues with doing a v8 swap.

as far as asking goes. i feel that walking into a project blind is just stupidity so if i can learn about other problems people have had with this it would allow me to possibly plan around or be better prepared to deal with them.

i understand this. i was not saying the v8 would make more power i was simply saying i had it and wanted to use it in a project.

if all i wanted was a rwd v8 car i would just buy a z06 vette and not give a shit about building anything. im interested in the project because i like to fabricate and i have the engine and tranny already.

my other choice was to build a mad max style car with the engine

Also look at the weight aspect. You are swapping out a 250lb engine for one that weighs 600 lbs.

I've thought about it and still might do it since I like to change engines every year anyways. An all aluminum LS would hardly be heavier than a 4G63 with manifolds, turbo, IC, etc. Plus it sounds way better, would look cool as hell, and is different. The hacked up chevy small block swaps look like crap, and are complete dinosaurs compared to the modern LS engines. I can think of a lot of reasons to put one in and make my car RWD, but I don't have the time or the scratch to tackle it right now.

 

[nitroazz]

I say go for it.

I was at an autoyard this morning and they had an ls1 sitting on the floor and I was thinking about it. It looked like it would be a lot easier than trying to fit the big v8 Porsche engine that was sitting beside it.

It'll be a lot of work with a huge learning curve for fabrication work but at the end of the day you can say. "I made this!" I say go for it.

On the other end of the spectrum I always thought it would be cool to swap out the 350 in my '89 Suburban and put in the 4g63. Man the engine bay is already big enough to hide someone in, imagine how much room the little 4 hanger would take up. Plus it would piss off all my muscle head buddies in the oil fields I work

eric's vr440, its a 440 with a supercharger making some 1500hp ish on a stock 3s rear end

something I hinted to in my first post, there's little logic in my opinion to swap in a v8 plus the dsm tranny weighs about 120 which is super light compared to what you'd be looking at to bolt on to the v8.
But hey if he wants to do it I guess we could try and help him out but that car will no longer be a dsm in my eyes.

that would be awesome, I know the rigger mentality to as I used to work on the rigs......just gotta shake your head at how stupid most of them are. Have you guys seen the video on youtude where a guy puts two 4g63s in a 1g? sooooo sick!

hasnt been a 440 for a while i thought. i thought he went up to a 500+ ci displacement with it.

To many wimps now a days. Seems like everyone is scared to be different, try something different or fabricate anything. If you have the right tools and some know how, I say go for it. I loooove to see things that are out of the ordinary.
