Guest Fulcrum Posted April 12, 2006 Share Posted April 12, 2006 Please excuse my ignorance as Nissan stuff is all relatively new to me. Honda, VAG, and 240SX's make up the bulk of my experience. My current plan is to swap a supercharged VG33E(Frontier/Xterra engine correct?) into a 280ZX chassis. Can i use a chipped Z32 ECU w/ Zcontrol to control the VG33E? Which supercharger somes on those engines M62 or M90? Before anyone jumps on me I know that a turbocharged motor will ultimately have more power. I want the instant response of a supercharger. This is gonna be a fun weekend streetcar/trackday sort of project. I'm shooting for about 380 peak horses and a wide powerband. I'm gonna have Endyne port and mod the supercharger and port the heads. If I need to I'll have them design a set of pistons to go with their headwork. TIA, Nate Quote Link to comment Share on other sites More sharing options...
Guest jbbatten21 Posted April 12, 2006 Share Posted April 12, 2006 I would think twice before using that engine. My father is an engineer at Nissan and when I asked him why the supercharged engines made so little power he said they had to detune them considerably to keep the lower end in tact. I have personally never driven a Supercharged Xterra, but the N/A Xterras with the 3.3 are quite slow. I think you would be better off building a custom centrifugal supercharger kit for the L28 than going with the 3.3 Just my opinion Quote Link to comment Share on other sites More sharing options...
Mack Posted April 13, 2006 Share Posted April 13, 2006 no. the VG33/30E® and the VG30DE(TT) motors are completely different. the DE's use coil on plug and have a variable intake cam, as well as a bunch of other things that are completely different from the E motors. I would talk to a member here named Bernard. he has been re-mapping Z31 ECUs for quite some time now. bigger, injectors, fdifferent fuel curve, different ignition curve, whatever you want. talk to him.

mtcookson Posted April 13, 2006 Share Posted April 13, 2006 The 89-91 SE and 89-94 GXE Maxima ECU's can be hooked up to a Zemulator and modified from what I'm told. Another option is the romulator for the chipped ecu's. Just as fyi, its a pretty common misconception that turbo setups produce no low end power. I know a guy with a turbo Maxima (VG30E) making nearly 350 ft. lb. of torque to the wheels at 2800 rpm and around 250 whp on a very bad tune (extremely rich). That was before some good head work and with a somewhat inefficient turbo (toyota ct26). with something slightly larger with a ball bearing setup it would spool just as quick and give even more low end power and best yet, hold that power till redline. roots superchargers tend to not hold power all the way to redline like a centrifugal setup can but most importantly... that M62 supercharger on the VG33 are way too small. If you absolutely want to go with a supercharger route I'd get a M90 at the very minimum. The best supercharger setup would be a screws supercharger as they are much more efficient than a roots yet still have the instant response. The only downside is they are quite expensive since they aren't as abundant as the M90's found on the Grand Prix GTP and such due to not being used in factory applications as often like the roots. Just some ideas. Quote Link to comment Share on other sites More sharing options...
Beck Posted April 13, 2006 Share Posted April 13, 2006 I trust Eaton parts as much as I trust the spray from a garden hose to stop a mack truck. Stay far away. If your not convienced, I can show you pictures of the mostrocities my co-workers sent out as good parts at the Eaton plant I worked in.

Guest Fulcrum Posted April 15, 2006 Share Posted April 15, 2006 Thanks for the info guys. I was hoping the VG33E would be a viable option. I guess I'll look into some other choices. Quote Link to comment Share on other sites More sharing options...
OK85ZX Posted April 25, 2006 Share Posted April 25, 2006 VG33E is a very viable option, just use a nice turbo with it and some sort of custom tuneing system ( Z31 ECU with a romulator or a full standalone ) Quote Link to comment Share on other sites More sharing options...
crazyFaizy Posted May 13, 2006 Share Posted May 13, 2006 hmmm,,,but isnt vg33 a truck engine..? so the engine bottom end is designed to do more tourq...ay..? so would that be better or worst..?.. Quote Link to comment Share on other sites More sharing options...
veritech-z Posted May 13, 2006 Share Posted May 13, 2006 doesn't that engine only make like 215hp stock? I don't know why they didn't just put a vq in the xterra like they're doing with every other model on the lot these days. Quote Link to comment Share on other sites More sharing options...
mtcookson Posted May 15, 2006 Share Posted May 15, 2006 I wouldn't consider the VG33 a truck engine any more than the VG30E. Granted it was used in their trucks and vans both of those engines have quite a bit of low end torque. Either engine would be a blast with some boost.

rxKaffee Posted July 25, 2006 Share Posted July 25, 2006 I believe the lower HP rating is due to the SOHC head design. If you're planing on using a vg33e and getting headwork done... I'd consider modifying a vg30de's heads to go on the block. You'll need to re-shape a water passage or two to get things to line up right. The main difference in the 33 and 30 is that the bore is increased. It uses the same crank, with a different snout. Quote Link to comment Share on other sites More sharing options...
Guest grahfz Posted September 18, 2006 Share Posted September 18, 2006 DE heads will not fit on the E blocks. the head-bolt pattern is different for a starter... fix that. vg33 is IDENTICAL to the vg30, minus the bore size, and the crank snout. with a turbo, it'll rip the wheels loose all day long.

crazyFaizy Posted September 19, 2006 Share Posted September 19, 2006 the engine i have is a 12v,,,2 cams per cylindees..lol..if fabricate a turbo system of ma own ,,carb or fuel injection,,can i eaily make a 500hp of it, ,? or is it a stupid project,,? the main reason why im using this engine becasue i managed a tbi intake style,,made by my friend,,using the old intake it self,,so its more like A small block but v6,,lol get it..?..another reasone is that our local dealer still provide everything for this engine (stock replacment parts:icon15: ),,so i duno,,any opinion,,?

After I realised my mistake, I had forgotten where I made this post. I have since done some more investigation on what modifications would be necessary for the swap. Not only are the water passages not lineing up, but oil passages as well. They were moved around to accomodate the larger bore on the vg33. I'm still trying to get ahold of some headgaskets to findout exactly how they would need to be reshaped to line up. As far as the head bolt pattern, I think that would just be a matter of filling in the old holes on the head, and re-drilling? Quote Link to comment Share on other sites More sharing options...
