What sort of a question is that 3.5s or 6lt motors ? Who would know if i wanted to stroke a 3.5 out to whatever who would know. When was the last time anyone checked to see if they are what there supposed to be ? But it is important that our Go pro cameras are bolted down i would hate to lose one. Ever been hit in the head by a bird while doing 100kph i wish someone had thought to have bolted them down.
the chevs dont seem too reliable with big horse power,so i think id waste my money on a vq35tt,or if your after reliability and not big horsepower the chev would be ok,,
I've often wondered why noone runs a stroked RB30 turbo. Straight 6 package is inherently better balanced and its so narrow it can just about go between the seats. Off the shelf bits for 3.2 litres and a reliable 9,000 rpm. All the R&D has been done by the drifters who also require lots of torque and reliable oiling with high G loadings. You are sacrificing some displacement and it is an older design but they have proven very reliable.

What about a stroked rb26det. big horsepower,lots of parts available and many tuner shops to build the engine u want,also light and suits any buggy configuration. Downside is they are costly.
You really want the latest technology with the biggest backing. The OP's original choices, VQ or Chev is where it's at for the pointy end of the field with controllable costs. The Toyota V6 isn't as well supported in terms of heads, rods, bearings, pistons, intake, etc so will cost more to build (and will have very similar power output). I went down the VQ route, it's a complex solution, but one that is certainly worth the bother. The only reason I'd go Chev is for the sound, and that, in itself may be worth it!
I'm running E30. Burning about the same volume as avgas, about the same HP, engine runs cooler. Engine sounds less metalic/tinny/ less prone to ping. I'm going to try E50 on the rotary.
I run E85 in my SR20de and have to use 550CC injectors to get the flow to keep the power up (stock are 259CC), but still leaned out number 4 and fried a piston. I am going to try 620CC on the dyno with pyrometers. E85 costs about $850 for two 205litre drums. I used almost exactly 4litres/km in Sea Lake
Again this isnt an option but there is Business in new zealand that make a quadrotor engine,looks and sounds awesome on youtube,pretty sure the hp is there too. just thought i'd throw that idea out there.
I believe that a few guys have looked at setting up their engines to run on E85 hete, however from what I have heard they simply cannot carry enough fuel in the cars to get through some of the longer sections such at races such as the Finke, etc. Knowing some of the mileage figures that some of the top buggies are getting when wound up and running on "normal" fuel, I would hate to see what the figures would be running E85.
E85 has 71% of the energy per litre as "regular gasoline", not even ultimate 98. You'd have to start on a consumption guesstimate of 140% of what you would use in Ultimate 98 for the same power, and no one would do it without power gains its wasting money. so you may as well say 160% of the ultimate 98 you'd use.
E42 - a 50/50 mix of E85 and Premium delivers very good power in dyno tests on turbo engines and is a lot more affordable too. Too bad we're not allowed to blend fuels. Redmist you might want to have another read of Schedule G.
