zr71, 1000hp single turbo 350z roadster

[jaz]

I doubt you've seen too many Z's that put close to 1000hp at the wheels.

Only downside to a mid mounted turbo is turbo-lag. There are many positives to a mid or rear mounted turbo, especially when the engine is built like his. He's got to be pushing 600+ from the block alone which is more then enough power to compensate for the turbo lag.

not in a z no. ive seen 700hp versions and thats more than enough for any street or drift car. your not going to be able to put 1000hp down on the street realistically. so basically it would only be good for the drag strip. and to my knowledge i cant think of any z drag cars? i know im probably wrong there, what i mean is theres usually easy cars outthere to extract 1000hp from. and thats probably because of the downpipe issue.
on the other hand i have seen lots of 1000hp vq35 engines placed in other cars. mainly gtrs because of the lighter weight and smaller size of the vq. awesome engine.

id definitely get some sort of bash guard for the turbo. are you going to do that?

Well my interest would be that If I went multi stage custom, I could sit higher than stock for bumps with a push of a button, and then back to about an inch lower than stock (for looks), and then do a multi stage system.... So that in different gears I get different rates... Low gears more squat, higher gears similarly soft suspension but progressively harder to increase high speed stability.

Yeah it's a street car, actually going to technically be a DD. Obviously I'm not going to roll around on the 1000hp setting, but there'll still be plenty of power on low boost (likely around 600whp).
The secondary goal behind that is highway queen and eventually a roll cage and interior strip down (retaining a/c, but loosing stereo, power seats etc) for standing mile purposes. But that's much further down the road. A few years from now likely just like the suspension lol.

Nice, i suppose if you use bags for a such a reason as yours that sounds like a pretty good idea, I have never heard of anyone using if like that, but thats prolly because I hang out mostly in the super ametour track/autox scene at best, and slammed classic cars on the other side, so it sounds like youve got it all figured out...I stand back and watch now, thanks for entertaining me

can i ask why you have the turbo setup down there? not really in the direct path of cool air is it. plus wont it get clogged up with all the crap from the road? every turbod z ive seen has the turbo in the bay?

Cool, yea in california your not gonna get away with the turbo sticking out of the hood, didnt realize this was a 1000hp street car, anyway, sounds like you have it figured out, I suppose on stock height the setup being where it is wouldn't be an issue, but I cannot imagine driving with that amount of power on bags, I mean you could go coils and dial it in still, I cant imagine wanting to be that low with that turbo setup where its at...no?

More than a few cars have done the mid mount on the z's now. It works to 680whp so far (that was on a smaller turbo and less efficient designed hotside piping).

Basically you can't fit the downpipe anywhere easily when mounting the turbo up front. Hal's car has a full custom radiator/front end support. I'm not as bold as that. Multiple top mount singles struggle with having a large enough downpipe to flow. Turbonetics kit is garbage past like 12psi for that reason (tiny dp with tons of bends), momentum performance is better, but they don't make much more than 550whp, just under 600whp rarely with a gt37 (vs gt35 originally) when in reality should be making closer to 700whp (with the proper hot side). Powerlab kits also had similar problems flowing, and the kits would just hit a wall in power. Also when you use those kits there is a lot more piping pre turbo which kills exhaust velocities.

Next, for a single, this is the simplest and straightest way to pipe the hotside.
Next, in california, not having a turbo sticking out of your hood is a good thing LOL
This is lower than the other mid mount cars definitely, but it uses longtubes which will increase exhaust velocities for sure and has the sideways mount turbo which will help even more. Frankly this should be the hardest spooling single out there IMHO. Too bad ill be rolling in the boost! I bet if I had a block that could take it I could have good power from 4k but i'll likely tune it to after 5k... 5252 to be exact.

When you work on one of these bastard cars and see how tight everything is STOCK, the appeal of remote mount turbos becomes very clear.

The lowest point of the kit is actually the front of the flange (manifold side) and the compressor housing is right after that. We have a bracket that supports the weight of the turbo (off the compressor housing) which we will angle up a bit more... Should get another oh half inch of clearance. Which will make the car totally driveable on stock suspension.

I actually talked to a guy yesterday about setting the car up on bags... that would be a nice idea... That way I can dial in the heights properly.

I'm not sure how building an engine and posting pictures of that is 'just parts' to you. This engine is a bitch. like a money hungry bitch that doesn't put out.

I like this, and I love your attitude.

[zr71]

I like the build thus far, not a huge fan of everyone bitching and moaning about someone questioning the build when up until 6 posts ago there was just pictures of parts, but I am glad that the build has some legit pictures now to back up the words...anyway, I cant help but question the decision to put the turbo way back there, wouldn't it make more sense to through it somewhere even above the engine bay and cut a hole in the hood, Ive seen that on several cars pushing 800+ HP but I have never seen anyone put a turbo that low to the ground or that far back in a car, just seems prone to getting hit...and hot as hell from the transmission...would like to hear your reasoning, maybe you are a genius and we are all still trying to figure it out

I've seen the Dynosty 350z run in Cincy. Wow. You're building a rocket

[Stupid Kid]

... it's like, why would somebody buy a ferrari or an aston when they could do this?

This is a 1000X cooler and fasterer and plus you get to build it yourself (the best part... next to driving it!).Props for doing a full out build bro, hope you hit your numbers and don't wrap it around a pole.

Also bitchin plymoth/chrysler van man.

.
Is the lowest point of the car going to be a silicone intake coupler??? .. I'm glad it's not going to be air-bagged, dragging floor-pans

[zr71]

moneyshots, and last post was on android... sorry for the crapshoot typos.




Wastegates still haven't been put on, next needed is the exhaust which I have all the stuff for already (vbands, flex pipe, vibrant muffler 4" aluminum).
Oil system is 70% done kind of. I have a bit of the hose, the pump the feed line, reservoir tank is being fabbed this week. The relay too... Fab only gets done on the weekends because my buddy who does it works weekdays, I don't mind and I appreciate how much time he puts into it for me.

<3

im in love. straight up no bull just doing it is the most effective route. always gonna be skeptics ignore em'. we need more time with you working on the car then screwing with these foo's and wasting time.lol
