Yep bone stock 2005 de

We modified the strut tower brackets …..and it’s a straight line specialties manifold.

Ok, you mentioned you blew up at around 450 chp. The thing is the turbo kits mostly use stock headers and small piping to be able to fit in the limited space. This make the back pressure really high, mine was 32psi back pressure at 15 psi boost, so…..the most gains I got where from going to a good header and back bigger pre turbo piping and better merge collector to reduce back pressure. Also the tuning is super important, cam angle can create massive low end torque and break the motor between 3000-5000 rpm, so I took 50 torque out of the spool up area using cam angle and timing to prevent motor failure. So far it’s working I’m at 525hp now still on my 160k motor 2 years in to boosting. You can always email me if you boost again and need anything. Gearheadsautofab@gmail.com

@GearheadsAutofab Thanks for the reply. The turbo kit I had was a twin turbo from a company called Power Enterprise. It came with its own manifolds and it was straight through exhaust, manifold back. I sold that car because after I bought a fully uprated bottom end package, it just kept overheating so the garage replaced all cooling components. Didn't solve it. The guy I sold it to, took the motor apart and notified me the garage I had fit the new bottom end, etc, hadn't replaced the head gasket, he re-used the old one despite me supplying a full kit. Spent a fortune, sold on cheap as faulty because of an old coot too proud to admit he forgot to change the head gasket. This rev9 looks like a good cheap entry point to actually get it FI, then upgraded from there. Your videos and info will be really valuable as I upgrade it. Tuning cars here in the UK is very expensive, especially turbo conversions, and I'm not mechanically minded so I have to rely on others. So your vids will help and I'll be sure to drop you an email. 520whp is crazy. It must be one of the highest power stock 350z's.

Ya the shop is in austin tx

@@GearheadsAutofab might head down there for a lil customization 🤣💯

Most tuners can tune for gtr injectors easily and they are a good size for non boosted

@@GearheadsAutofab Thanks for the info. I will look into it.

Yes 670 and it was only limited because I couldn’t get it to make more boost on the dyno. Yes it’s wheel hp I only have a in ground roller dyno that test at the wheels. But all dyno numbers are very slightly so numbers are not super important. The biggest thing is that I cut the piston ring gap big and because the Nippon piston has lower compression it takes a bit more boost to make power, however it takes the pressure off the part of the block that usually cracks. So far I have lots of dyno testing and 3 track days on it and a little street driving and it’s still fresh and running grate. Also I made 450 on 93 pump gas and ran it at the track in 100 deg weather a it still didn’t break. I do think it’s the cheapest setup at this power level I’ve ever done. Car went 11:1 on 450hp on the hot day

@@GearheadsAutofabnice around what crank HP woke you say 670hp is in a B series ?

Maybe like 730hp ….. people say it’s like 10 or 15% something like that

@@GearheadsAutofabwhat’s the most you think that setup can handle HP wise ? Could you make 750-800hp

Yep I bet 800 is close to the limit

I designed a kit to move the heater hose pipe to the passenger side….then I built a 3 inch down pipe and it allowed the driver side header to fit. The kit is for sale on Www.Nisdaautosport.com

Grate idea, I thought the same thing , way back in one of the first vids on the turbo kit I upgraded from the eBay t3 60-1 turbo to a $2000 precision ball bearing 62/66 turbo …..turns out that it didn’t help allot until changing most of the rest of the turbo manifold parts. Even a grate turbo couldn’t do its job with a restricted manifold. Also Garette is awesome as well.

You should definitely still make the video…. I’d watch it. Also, if you have any questions hit me up because I spent two years learning more and more stuff about boosting these cars. They are so much fun with Turbo!!

Funny thing …..I have that book on my night stand started reading it like a year ago good stuff!

I think the biggest impact was Headers, Ported v pipe / crossover pipe But you will have to make a new down pipe to fit headers. They won’t fit on the original kit

Eventually…..but that’s allot of work, and parts and upgrades……I want to make as close to 600hp on a basic pump and injectors as possible. Just to see what’s possible on the most simple setup Eventually I will have to do e85 probably…

OK for sure can’t wait to see more progress on the build on the road to 600 I really appreciate you sharing the knowledge and not gatekeeping your videos help me and so many other people thank you

what’s the optimum size for the uppipe? 2.75” or 3”? I thought it was best to keep the size the same as the exhaust inlet.

@@StreetHeem 3" would be optimal, into a turbine housing that can handle it. That's for peak power though. With the 2.5" used here it becomes a back pressure issue at peak revs, as does the T3 flange. But anything below 500hp the smaller tubing helps spool.
