I am adding a supercharger, I am experinced in rebuilding pre-80's era muscle, but I am a noob with the imports. What I want to know is since I am also doing a bottom up re-build should I go ahead and swap out cams, Pistons, rockers/springs, and heads? Do I need to upgrade my ECU or just have it re-programed after the change? I want to be at 400-430 RHP when I am done. I have no desire to turbo the engine. Alsp, do you recommend building up the tranny since I am running an AT?
Also who makes the best ROOT type supercharger?

Any suggestions will be appreciated.

These new threads lately...

 

In.

 

Me tooooooooo

 

Bomb350z: Everyone on here is an Expert (or at least they think they are), so ignore the comments that are coming your way. Look above to the Vortec Thread. If you want to go 400RWHP, you can do so with that with out building the block, some have pushed over 500RQHP on the stock block due to the low TQ in the application. 400RTQ is where the stock rods start to snap although some have done it with less HP and TQ. Its all about the tune and driver.

I am a bit older myself so I can appreciate your post. Most of the people here are internet savvy and expect us older guys to understand things right off the bat.

1. Only the Stillen Super Charger has been made for the VQ35 engine. ROOTS
2. I put down 410RWHP with the Vortec Ttrim blower and the 2.87 pulley 327RTQ
3. Search the forums for key words: Roots, Superchargers, etc. HKS makes a great blower for these cars too.
4. Be prepared for INTERNET SMART AZZES to make fun of everything you ask or post.

If they had have a brain they would read your post and figure out an age range, then understand that you maynot be the most clever guy here on the fourms. It took me a good few months to get this forum down and I work in computers for a living.

All your ideas are on point, but most are overkill for this platform. You have to throw out your old traditional ways of thinking. The car (2006z,2005g) came with 355s in the rear end and 300HP at the motor. Thats impressive. To obtain that much without the use of the V8, the heads and cams work extremely well. Now some Jackazz is going to get on here and try to prove me wrong but for your power level goals, dont spend too much money on parts that are over kill. I would buy 4 stock long blocks and just run a Vortec SC at 14psi until one lets loose, swap, keep going. I have two stock long blocks in storage just incase. So far so good.

Are you going to track the car? 1/4 mile or road race?

A buddy of mine with JWT Twin Turbo with a built motor. I did upgrade the valve springs, but used the stock heads and cams for that matter, augmented fuel pump and injectors he put down about 560RWHP. I think he even had the stock radiator in the car with no coolant issues. he did have the NISMO thermostate as do I.

Roots wont get you want you need without a good shot of NOS, about 75-100 on top. The Stillen Blowers are good for about low 300s RWHP, but if you build the motor for NOS and not the SC, then the two can easily get what you want done with daily drive- ability.

Tranny
Also search for the tranny upgrades on here. I think after 350RWHP its a good idea to build it up. Plan on using manual mode from that point on, in Drive the car will shift like crap.

Roots SC and TT owner:
PM SuperChargedG and ask him about his Stillen Roots SuperCharger experiences vs his now Greddy Twin Turbo experiences with his Auto. He is also older and can appreciate your newness vs. the internet thugs on her that pay people to work on their cars to get 700RWHP and think there cool.


ECU:
Not until recently has the IMPORT world got a effing clue about stock ECU upgrades. We had BS generic flashes but nothing solid like we do not. Unlike the Muscle Car World. The UpRev Osirus Software is relatively new, but very nice. Its not like the older cars. EVERYTHING was piggy back until the UpRev came out and thats withing the last few months really. (6-9)

google shortblock or longblock VQ35DE and look at the parts list. Again what you do yourself maybe different.

 

4shizzil, I appreciate the advice. I know most of these guys on here think they know it all. I have 12 year old kids just like them, its no big deal they are quite easy to tune out. I only listen to those who know what they are talking about and build their own engines. All the ones that pay others to do what I do with my own two hands probably couldn't find their azz with both hands and a GPS to point the direction.

I do plan on racing the car but it is also going to be a regular driver (not quite daily) as well so that is the reason for not going much further than 430RWHP. I am not a huge fan of NOS, I know you can get instant cheap power from it but I prefer to build my HP.
I have my 68 that I race straight track so there is no need for dumping a lot of money into my Z (yet). I started searching the VQ35DE and there is def a lot of possible mods. I will be getting back with you if I have any further questions.
Thanks again.

 

You may want to consider all your options before making any decisions. Roots style superchargers have had very little success on breaking the 400 mark on this platform. Vortech is well established in the Z community and seems to be the most popular supercharger available for us. HKS is nice but pricey. Also most vortech owners will tell you if they could do it all over again, they would have just gone with a turbo. Also turbo Z's seem to get alot better mpg's than superchargers. Do a little research and make you decision based on what you feel is best for you. I see you live in Florida. If you live in south Fla, come to one of our meets I'll give you a ride in my Z to see if this is the route you want to go.

One of the reasons for not wanting to go turbo is that I want power throughout the RPM range, not just after a certain RPM for optimal boost. I have talked to a few guys that run Superchargers and they say that they are good for instant power that lasts well into the RPM range. The drawback being that you can not get serious HP gains like you can with a turbo or twin turbo.
Again I am new to this and am still learning the ins and outs of turbo vs Supercharger. I greatly appreciate the advice. I am definitely going to do my research before buying.

 

Me Likey Stillen, Mucho HP and so much fun too, blown belts, bad bearings and 320rwhp, hooeyyy

 

Traditionally speaking you would get instant power with a roots style supercharger, however on our cars that is not the case. With the stillen kit (eaton blower) boost does come in sooner than with a vortech, but the Vortech can be modified via smaller pulleys to accomplish the same thing with the benefit of gaining more top end power. Take a look at a powerlab dyno plot and compare it to a Vortech dyno plot. You will see that the turbo spools alot sooner than the Vortech and the TQ is unmatched. The best way to describe the feel of a vortech powered Z is it feels like a naturally aspirated Z with more power. A turbo will give you more of that instant power you are looking for and they hold very well on our cars. I come from a muscle car back ground myself so I think I know what your looking for power band wise, and turbo would be the better of the 2. Also you mentioned you are looking to build your motor from the bottom up. Having a built motor turbo Z will give you a very safe 450-500whp.

 

 

Oh my....ibtl.

 

Looks like a mid-life crisis thread to me...

 

Not sure why u guys are ragging on this guy... He seems more inclined to start this build than the other thread of "Help me pick which single turbo kit to get" and that guy has like 5-6 pages of people giving him serious opinions on which kit is better. Not sure why he gets a pass n this guy doesnt.. but oh well..

Bomb, I would also re-consider which route to go with... Single turbo or tt set-ups are far superior in better and if ur gonna be racing the car you most certainly will always be in the powerband where the boost will always be there. S/C's cost about as much as a single turbo.. Why pay the same amount for less power ya know?
As always search will help... good luck

 

check some other options, research, and listen to the experienced people around here. I'd definitely go TT or ST over any SC system anyday BUT I'm CA FML

 

i have a vortech. I steered away from the stillen kit because of how your motor is constantly in boost. its nice to be in vacuum and build boost. I would also aggree that i would have gone single turbo if i were to do it again. The boost comes on faster and stays there where as when you hit full boost with the vortech its time to shift. If you just do a simple ST setup and shoot for right around 400 whp that would be fine and be the best for what you want i think.

 

First off welcome to my350z.com. I know I'm going to get flammed for this, but...I would ditch the FI route and go with an LS swap. There are plenty of threads on the the Z's that have had LS swaps. Most go with the LS2/t56 combination. I had the opportunity to do any type of FI I wanted after much research and my driving habits I need a nicely powered n/a engine that is easy to mod. Do some searching on here and on google. There are plenty of examples out there for you.

 

I have JWT TT kit and I get my boost almost instantly using smaller turbos you may sacrifice a little on top end but on a stock block you really dont lose much at all.
