you think an iron block twin turbo charged I6 will be lighter than a NA all aluminum V6? even with the difference in displacement, i doubt it.Exar-Kun wrote:neither engine setup will be lighter than the RB26Dett
Even though it's aluminum, a V6 has a lot of material. The block itself is much wider to accomodate 2 banks of cylinders. There are 2 heads, and while both are shorter, there is still much more material used. Now I don't know the weights of either, so this isn't to say which is heavier, but a V6 is indeed heavier than an I6 of the same materials. An aluminum V6 might even be heavier than an iron I6.cdlong wrote:

there are a couple of guys on freshalloy doing the swap right now.
i don't believe that. first of all, the driveshaft is shorter. it might not save much weight, but it certainly isn't heavier. if you imagine taking an I6 block and cutting it in half and joining it on a common crank like a V engine, there will be a good ammount of material that overlaps. the V shape is naturally stiffer because of compressed nature of the layout. you can use less material because of the inherent stiffness thus making it even lighter. width doesn't make a difference, an I6 is longer, but dimensions don't change anything, just how much material is used.C-Kwik wrote:Even though it's aluminum, a V6 has a lot of material.

V6 heads and an I6 head cut in half are virtually the same except for the extra cam gears and whatnot. the V6 parts would weigh more, but not much.C-Kwik wrote:There are 2 heads, and while both are shorter, there is still much more material used.
for the reasons i stated i bet a V6 and an I6 of the same material are very close in weight. however, if you take off two turbos and make the block aluminum, the VQ will certainly be lighter. the only thing the VQ has going against it is the displacement.C-Kwik wrote:Now I don't know the weights of either, so this isn't to say which is heavier, but a V6 is indeed heavier than an I6 of the same materials.

You can do google search to find out.I6 is indeed much lighter. In design, V6 require counter-balance in crankshaft oppose to I6. The extra weight also comes from bigger head (2 of them actually), double cylinder block, timing belt/chain component, oil/water runner, wider intake & exhaust manifold, and etc.cdlong wrote:i'd have to see some hard numbers to really be sure though.

Wow man, thanks for the compliments!S13 Charlie wrote:WOW!!
You are a god among insects!!! All that, and a custom intake manifold too! Beautiful work bud, it looks like you really planned this swap out. And all those people who are worried about the weight of a v6, look how far back in the bay that engine sits. That is going to be one sweet ride when it's done. Are you in socal? If so, I'd love to check out your car when it's done.
cheers,C
--to some ppl it might not be worth it, but when it comes to originality its worth it. rb26dett swaps has been done numorous times, im sure there are onli handfuls of this kinda swap done. props to him and also yeah keep us updated, im also lookin forward to seein how this comes out. i think its more of tryin to be original than anythin else. and also u could look at this from a domestic p.o.v. is modyfyin ur 4cyl nissan/honda or any imports worth it when u could get a v8the_ace wrote:is it really worth it in the end??
300hp na
vs 320+ hp from........ maybe tt rb??

I'm still working on this project, updates can be seen at http://www.engineswaptech.com
I got it running on the MegaSquirt standalone but it's not tuned yet, still working out the bugs so to speak.
The LH exhaust manifold has to be modified to clear the shaft, it almost clears but not quite.
It's gonna be featured in SCC in a couple months, keep an eye out for that.
I'd like to invite all you guys that are attempting this swap over to my site. Please log in and post up about your project. I'm trying to get all of us together on one site so we can compare and help each other out. http://www.engineswaptech.com
thanks!Fred
