I was wondering this too... would be nice to have a turn key version of this mass produced. I would so be on a group buy. . . . like right now!:happydance:

I could make a little batch of those later in the winter once i put the car on the lift. I managed to put 8900 or maybe 9000 miles on it now in less than 4 months since I tuned it! damn!!! my car is getting high on the mileage now.

once I get it on the lift for a while to go over everything and see how its all holding up, i will probably take a couple things apart to go over it... if not take it all apart to replace the engine with my built one whenever thats done. Part of me wants to just get the other engine all done and ready to swap in, but leave it out of the car and see if I can get a 10 second pass out of the stock engine with the 18x12 wheel/tire setup.

That's wassup. I don't think that your milage is rising that fast. Heck, you are putting in enough maintenance to keep up with a few Zs, lol.

Please let me know when you do run off some or your "special parts".

Im not sure if this was answered earlier but was the cost for this build in total... rough estimate without your discount you spoke of due to no wastegates... just want to see if this is a little shy of my plans...

phunk how many ports on your vacuum manifold? I found this:

42 Draft Designs

and

Vacuum Block- TREADSTONE PERFORMANCE

For EWGs, BOVs, Boost Gauge and EBC how many ports would I need without using T's? 6?

it currently has 4 small ports and the large in/outs on the end. i have one large used for the "input", the opposite end large one for the output to the brake boost, and the 2 small ones for the boost controller. the other 2 small ones are looped to one another. its a part i made for my 350z a long time ago and just moved it over so it had more ports than i need for now. my BOVs are T'd off the vacuum lines near the throttle bodies on each side

Great find Ron!

Once I get back to the states, I am going to have to look you up dude. There are a few more things that I want to do and those include wire tuck, vacuum/boost cleanup, and forged internals (possibly a re-tune). I need to see the beast in person to have a good model to go on.

This thread has been a very interesting read! Thanks for sharing your build

Thanks. Just the other day the car surpassed 40,000 miles on the odometer, and about 12,500 since the turbo install. Still on the factory original spark plugs, still yet to ever have any service required since the turbo install other than oil changes. Overall the car has been great.

In the next two weeks I will be taking it down for a little bit to go over the car and make sure everything looks good for another year of duty. I will be replacing the front pads and rotors (my fronts are pretty warped now), and maybe the rear. I am going to investigate the shocks and possibly replace them, I think they may be starting to show signs of wear, possibly from having the car lowered on the H&R springs as stock shocks typically wear out faster like that. I will be inspecting all the ball joints, tie rod ends, and wheel bearings for any play or wear, and of course replace as needed. I will give it a full underbody detail job and touch up any signs of corrosion under there. As for the performance stuff, I will be checking all the turbo system tubes and couplers. I will check my oil cooler hoses for any wear from chassis rub, etc. Pressure wash and detail the engine bay. I will be inspecting the fuel pump assembly and in-tank hoses for any detoriation from being a 100% E85 car ever since the turbo install. Change the spark plugs for once, possibly do a leakdown test on the engine... and lastly put it back on the dyno and clean up a couple spots in the tuning I have found need some work the last year, and try some runs at the higher boost I have been running on the street to see what power its at now.

UPDATE:

Good new and bad news.

The good news is, the car has been flawless. I have over 18,000 miles since the turbos were installed, by me, and I have yet to be very nice to the car at all. I have managed to kill the brand new 305 30 19 Toyo R888s in one season of street driving. In this 18,000+ miles of boost, the car has not been serviced once. Forget my last post above, the front brakes are totally shot now, just in time for winter storage. Everything has checked out perfect. Nothing has worn out or failed.

The bad news, I think I am ready to move on to a new platform. I have had a GTR in my possession for a couple months that was borrowed to me from a friend/customer who was giving me an opportunity to design some products for it. It was already a deep 10 second car on its arrival here, and it has a built trans (shep stage 2 IIRC), and he has allowed me to get more than my fair share of wheel time in the car doing datalogs for him before he picks it up tonight. I think that I officially have the GTR bug, and need to start preparing my situation to make that step. The car is a little out of my league price wise, but I think that I can make it happen if I use this winter to just relax and not blow money on stupid xxxx.

I am going to write another post which is going to list what it is about the twin turbo 370z experience I have enjoyed, and what about it has driven me up the wall (not much).

Also I have attached the dyno sheet from when I originally tuned the car.

You can see how low the boost was as I was graphing it there.

PLEASE note that I am not a professional EMS tuner... I did own a dyno for several years and I used to tune cars regularly, but that was quite a while ago for me and I had not REALLY tuned a car in a couple years. On top of that, this was my first E85 tuning experience, and my first UPREV tuning experience. I guess I did adequate as the engine is still in one piece!

I believe that there was quite a bit of midrange power that I left on the table. I was having a very difficult time getting my ignition timing to behave how I wanted it to.

I did end up turning the boost up, and I normally run around 9.5psi now. I have not dynoed it at the higher boost yet.

I have the smoothing set to zero, so pardon the bumpiness there. Normally I can tune that out but I was not good enough with the Uprev yet.

Actually sounds like great news to come. I'd do the same if I could. But maintence on the GTR is out of this world too. Such as brakes and tranny if you push bigger numbers. Can't wait for your review.
