LMAO Like this: This is my toy im working on. See It isnt hard, You can add whatever single turbo you like! L8tr E
Yer it will be. Getting there...slowly! Ill make another thread on it sometime soon. Dun want to hijack this one! Only showing that its not hard to add a single turbo to a V6 thats all. L8tr E
Both are a twin cam engine. Just because the VG30DE has four cam shafts does not mean it is quad cam. Both engines have 24 valves, only because the VG30 is a V instead of a straight, the cams are halved. Don't believe me? Read the strip on the throttle cable cover
Well it cant be that hard seeing as the original 300zx is single turbo on a V6! But that's a little on the small side still, what is that a T3?
Guys, BANG BANG - thats all that matters Why do some people think the angle of the V somehow transmits more power to the wheels? The only difference of substance, is that a straight 6 has less counterweights on the crankshaft (this means less rotating mass, a bit like having a lightweight flywheel) Apart from that, what is inside the combustion chamber (such as stroke, displacement, and the efficiency of the heads in filling that chamber) makes the difference this is just my opinion - if I'm wrong then I'm happy, cos I can learn something new
Sorry, but I find this "comparison" rather inane. How possibly could a 3 litre V6 be compared to a 2.6 litre straight six in the same breath??? Thats 400cc...........thats a lot of difference in my view. Work out the percentage for yourself and then work out the percentage increase in those dyno figures on the side of the VG then. Why not compare a VG30dett to a blown Alloytech (Holden) V6? Quad........errr, sorry, 4 camshafts, 60 degree V6. Well you cant because the Alloytech engine is so many hundred cc's bigger again. Those dyno figures are stating the glaringly obvious, one engine is bigger than the other......gee that wasnt too hard to work out was it? Hey, while were at it, why not compare a turboed VH45...its only 2 extra cylinders and another 1500cc's isnt it? Its a Nissan tho! That should qualify it shouldnt it? Surely theres some useful parrallel data there..............pl-leeze! The similarities end with the number of cylinders and the name stamped on the block....... Secondly, getting pedantic about the generic term "Quad Cam" for a 4 x camshaft engine......whats that all about FFS?? The engine has 4 camshafts. Quad cams. Its a generic term only. On that rationale, an 4 banger engine with 4 throttle bodies isnt necesarily fitted with "Quad Throttle Bodies" then is it? So , VG30det/tt's have 2 throttle bodies, does that mean they dont necessarily have "Dual" or "Twin" throttle bodies?? Well, mine does because it says so on the plenum!!!!! Nyah nyah nyah! The only possible comparison that means anything at all as far as an RB v's a VG is between a VG30dett and an RB30 fitted with a RB26dett ( X 2 cams) head!!! LMAO!!!! Then again its a moot point as one is stock and one is a (very trick) hybrid..................... Bah! No discussion at all! L8tr E
Iddy biddy! Same factory turbo as in the Z31, you've got a stack of room there though! T31/T04E 60-1 or something similar would do the trick! GT35R if you have more money! She'll fit!
Hehehehe yer "Itll do donkeh"! Enough to get it started and running. Think T51! Id better start another thread for this. L8tr E
:bash: thank fk i didnt have to wind up my bashing stick. ...end rant? I didnt bother reading your "tone" so i dont know which side of the fence you sit on but alas. They are comparable as they were of the same period and used in "performance" cars, by the same manufacturor. for a mathematical comparison of VG30 vs rb26: letting VG=1 would make the RB=0.8666 (as shown by 3.0/2.6) so two similarly set up engines (ie vg/rb) should be same turbines/compressors, same satic AND dynamic compression ratio, same AFR tune, same inj CC's (which if AFR is equal that is redundant, redundant anyway because at same duty cycle CC's would need to be different). that is a decent comparison - which is close to what the origanal article put forward. ...now ready for the spanner in the works? Its all FKD... the two "engines" should be using turbos of 1 and 0.8666 comparative size. so for lack of a better example the vg should have two gt35's and the rb should have two gt30's then the two torque curves would be PROPORTIONALLY similar but the power will be (my estimate) 79% that of the VG (when speaking of the RB) ^^^this is taken from the didplacement difference of 400cc then factored by 1.7x anyway..... you want mid range and streetability?, take the 400ccs. Qn: how many 10sec skylines run around the (circuit) track in Aus?
An inane comparison? :biggrin: Its stating the obvious to point out the cc difference but thats not the point. Which is to compare two six cylinder motors from the same manufacturer, the straight six often being stated to be a far superior motor. The straight six may be a more practical motor to upgrade and to swap in but that doesn't make it a better motor, as the comparison indicates. But at the end of the day its usually about bang for the buck which is where the straight six usually wins.
why isnt the new gtr a straight 6??? weight distribution and cg that is why..... the gearbox is rear mounted and the weight of the engine can be mounted lower and further back in the 35gtr useing the vee configuration because it is shorter and not as tall as an inline which has allowed engineers to even out the f/r weight distribution of the new model and lower the cg.... the vg is considered a more sophisticated power house with tuned intake runners and variable valve timing, this created more torque but the longer runners are tuned to make power lower in the rev range compared to an engine such as the rb with short runners.... has anyone tried to fit a vg in a 32 gtr??? my guess is it wont fit. they are both exceptional engines but both made for different things, vg for a GT which wants a nice grunty engine for touring and the rb for a track car which is going to be reving and in its power band when being race anyone agree with me on this one?
VG would fit easy in a R33, the VH's practically drop in... Different mounts and sump and I reckon the VG would look little in that engine bay.
hmm... are u talking about a gtr or a gtst?? i think the diff would cause some problems from what i have seen with a friends 32gtr or is there another reason u think the straight six is better for the 32 33 and 34 gtr compared with the vee in the new one???
