Guest 95TT Posted December 8, 2005 Share Posted December 8, 2005 I have been doing some researching and have not seen the swap yet. Please only serious posts please. I am contemplating the swap because of a few reasons. First, the obvious discplacement would be nice. Second, the VG only has 4 main bearings. In my quest for 900-1000rwhp, it seems the bearings would not withstand that type of punishment. If anyone has seen this swap or could point me in the right direction I would appreciate it.

mtcookson Posted December 8, 2005 Share Posted December 8, 2005 Are you talking about replacing a VG30DE(TT) or a VG30E(T)? If its the VG30DETT you can get some incredible power out of it. The only benefit of going to the VQ really, would be that it is much lighter. I don't know of anyone that has made quite that much power out of a VQ30 but there is a guy with a full 350Z drag car making 1600+ horsepower out of a heavily built VQ35. Runs 6's in the 1/4 I believe. I'm pretty sure it is now considered the fastest Nissan in the world. With lots money and knowledge you should be able to pull it off with either engine really. Also, the VG30ET's aren't to be held lightly either if that's the one you're talking about. Electromotive took a VG30ET and built it for the Nissan GTP cars. They produce over 1200 hp for qualifying and produce 900 hp for the races. This is using the stock block and heads (i.e. no recasting). They later did recast the block out of aluminum for even more reliability but in its stock form did well enough to win quite a few races. Oh yeah... this was in the late 80's early 90's as well... with a lot of car technology where it is today that shouldn't be hard to meet or surpass as well. I believe there is a guy with a Z31 running in the 7's with a VG30ET as well. I can't remember his name at the moment but you could likely find him on the NHRA's website.

Escort racing is making over 1300rwhp but they are changing the main bearings after every race. That would not be fun. It seems after about 800rwhp the main bearings are going pretty quick. I guess I will have to do some more searching. Quote Link to comment Share on other sites More sharing options...
mtcookson Posted December 8, 2005 Share Posted December 8, 2005 Could always use the VH45... they are some awesome engines Quote Link to comment Share on other sites More sharing options...

87Kevin Posted December 10, 2005 Share Posted December 10, 2005 Well if you're talking about replacing the vg with the vq, what's the point? both are v6's with 4 main bearings unless I'm missing something. Have you ever seen the main bearing structure on a vg? It's insane, cast iron block with all 4 main caps cast into a one peice girdle(vg30et). As far as v6 main bearings go, I dont think they get any better. If it really concerns you, get an I6 with 7 mains. Quote Link to comment Share on other sites More sharing options...
RedBeauty84ZX Posted December 11, 2005 Share Posted December 11, 2005 Cesar Febus! I was just reading about him in my turbonetics catalog today. I dont believe this is Cesar's as his is white, but here is a 8 second Z31: BTW BLOZ UP, what part of SA? I live in Schertz. Quote Link to comment Share on other sites More sharing options...

84z31 Posted December 13, 2005 Share Posted December 13, 2005 does anyone have specs or a web link to that baby. thats pretty sweet! Quote Link to comment Share on other sites More sharing options...
1FASTKINGCAB Posted December 13, 2005 Share Posted December 13, 2005 I dont believe this is Cesar's as his is white' date=' but here is a 8 second Z31:[img']http://z31.com/~morgan/nd/z/8secz.jpg[/img] That car is white now and it's best ET is 7.6x As far as a VQ35DE in place of a VG30DE I don't see much point to it spend the $$$ on a TT swap. I'm not bad mouthing the VQ but it seems like they work for 350WHP in street trim. while the VG30DE-TT will do 400WHP for the cost of the greddy TT kit or Stillen blower systems. I seems like backwards engineering. just my 2 cents The cost would be insane, just go for a RB26 swap If you want 900-1000hp for the street go for an RB you can get 800 out of the VG and I have NEVER seen a 800WHP Vq Quote Link to comment Share on other sites More sharing options...
mtcookson Posted December 13, 2005 Share Posted December 13, 2005 I think the VG would be faster than the RB, it makes so much more torque and much lower in the rev range. Actually, its been proven to be faster the majority of the time. Never seen an 800 whp VQ? How about a 1600+ hp VQ? http://www.theexperience.com/recordrun.htm Quote Link to comment Share on other sites More sharing options...
260DET Posted December 14, 2005 Share Posted December 14, 2005 A custom exhaust system with a single turbo is a lot easier to do with a straight six compared with a V, turbo theoretically is a bit more efficient too. Thats the reason most straight six advocates give anyway. Personally I prefer the V, better weight distribution, shorter crank. Quote Link to comment Share on other sites More sharing options...
mtcookson Posted December 14, 2005 Share Posted December 14, 2005 Putting a V6 into an engine bay designed for a I6 actually gives tons of room to slap a turbo in front of the engine. That seems to be the best way to do it imo. Quote Link to comment Share on other sites More sharing options...
