So does it say how much he spent to get 370 rwhp N/A?

Elmo370z 04-04-2016 12:47 PM

Close to 15

shadow85 04-04-2016 04:57 PM

Not bad, that $17K US I would assume, which means it would be around $25K AU for me.

Not sure if it would be more worthwhile to spend $20K AU to get a full TT kit with ~350 rwkw.

If you want power and keep it streetable, go TT - there is a shop in Melbourne that have done 12-15 kits.

I can tell you exactly how much it costs to get 500hp at the crank with a VQ as I am 70% the way into such a build. Assembly will start as soon as we take delivery of the ITB kit and re-check flow-bench numbers with the induction system in place.

I'm happy to share info if you want to PM me, but A$25K won't be enough.

Yeah I figured, I thought NA would be nice just to be different. But I guess I want power!

I was beaten by an Evo 8 lancer in my stock 15' Z last night, not happy lol

Elmo370z 04-06-2016 01:02 AM

At a track they did roll racing and i beat an evo 10 with intake, exhaust and a tune, in my 09 just with stillen G3's intakes and no tune.

This. My previous STi had pretty much everything you could do while keeping the stock turbo, and from a roll a CAI/HFC/tune G37 would walk away once we both got to higher gears.

if the evo was stock then yes it's most likely driver mod

Elmo370z 04-06-2016 04:35 PM

It had exhaust intakes and a tune. Stock is such a vague description. Even if his car was faster he still wasn't catching up to me, I kept my eye on the mirror

shadow85 04-07-2016 09:01 PM

I don't think the EVO was stock. And yes I can drive. lol

I have been watching alot of EVO v 370Z videos on youtube, and it seems the EVO is slightly faster in all the videos up until about 4-5 gear where the Z starts to overtake slowly.

Does any or 1slow yourself, tell me a little more about the dry sump set up. I was talking to a guy today about the possible locations, They are wanting to move things around in the engine bay and im convinced that pretty much out the question, I don't want to start hacking up the car. They thought about putting the tank where the windshield wiper fluid is located. I still want to go through the truck. Then the question came up with the routing of the lines? is it possible to run the lines through the chassis, Just so they aren't expose to the elements? The next question would the pump be strong enough to feed oil to the motor while road racing, Im pretty sure Daily makes pumps strong enough. ( These are muscle car guys that don't partake in our platforms). If there is anything else missing please feel free to chime in.

I ran one hose down each side of the car under the side plastic panels on the bottom think where the fuel line is, they the came into the car under the seats where the bottom of the floor dents back down, and then through the pass through by the strut tower/fuel pump cover and ove the hump to the back of the trunk area. The breather can is behind the bumper by the rear crash bar. If you go with at least a -16 line from the tank to the pressure stage you should be fine but a -20 is really the way to go. From the scavenge stages to the tank should be -16. The massive supply line actually acts as a supplemental tank and is always full of oil since it is so low in the middle. The pan pump i used was of my design not a daileys and used a peterson r4 pump with an oversized pressure stage and custom pump bracket from the ati drysump balncer. Vant remember who i got the pulley hub from but i believe it was cw. Lines where flex aramid line exept the pressure lines which were mocal stainless. When setting it up watch the drive ratio on the cog belts and the pumps rated max rpm. Dont want to blow your pump up.

welp unfortunately i have some family health problems, need to relocate to spend time with them, with all that i don't have the leeway to purchase it anymore so if anyone wants it just message me and i can put you in touch with the owner if you're serious enough about it.

I know how you feel. I lost my mom and first wife to cancer. They died 2 months apart. Mom in March, then Jacqui in May of 2011. :( It's hard on all family members and friends.

Okay due to much requesting here is a run down of the build and parts used. The car is an 09 sport 6mt and since I live near GTM I dropped by and went over what I wanted with Sam and went ahead and dropped my car off. The project was set to take a Mid level approach to an NA build as I wanted to see what could be done on the stock block and heads, and I also wanted to prioritize mid range power to suit my driving style and only moderately increase Upper rpm power. The plan was layed out to include a new manifold and fuel rails, new throttles, new intakes, new headers, open exhaust but still quiet enough to drive it around, a bulletproof clutch setup, dry sump oiling, increased cooling, and to run dual fuels and see if there was any gain to be had on E85. *as I get more pictures sent to me I will add them in here*

http://www.the370z.com/members/1slow...imag0409-1.jpg


http://i313.photobucket.com/albums/l...ps5f590962.jpg

For the manifold it was decided to go with the GTM ITB setup, but it was custom converted to twin 3" throttles and DBW to run on the factory ECU(VHR throttles would also work so that the setup could be used on a car without swapping the throttle bodies). To go with the bigger manifold and throttles a new 3" cold air intake was fabricated using two GTM stage2 supercharger 5" air filters and velocity stacks to make sure the air had a completely unrestricted path to the valves for maximum power. As I track the car occasionally it was a must that the whole setup fit under the factory strut bar as well. New billet fuel rails were made to match the new runners and setup to supply them from the factory returnless fuel line was made since going returnless wasn't worth it at this point in time.

In order to spin the car up past 8000rpm more reliably as well as avoid any oil supply issues a dry sump was decided upon to lubricate the motor. I looked into the existing Dailey's Engineering kit and was going to purchase it until i got the final price and broke out in a cold sweat, since the pan and pump was $7000, needed a custom solid aluminum motor mount, and there was like $10k additional in parts to get the pump to fit with the accessories and actually make the system work. After talking to Sam I decided to let GTM develop a new cost effective solution to this problem and he came through with a Billet oil pan, Peterson Fluid Systems R4 4-stage drysump pump, and peterson tanks,breathers, filters. In order to keep the costs down it was decided to make a billet bracket to replace the air conditioning with the pump and make the pan so that lines could be run to it. The A/c can be reinstalled down the road by using the GTM Bracket kit to move the alternator and power steering up and mounting the pump on the passenger side but for now I decided to save a couple grand and drop the weight of the a/c system. Oil capacity is now 12.5 quarts and I need to install a smaller cooler in the system as my oil temps have not gone over 190 since the system was installed. The kit also uses a high capacity racing oil filter and light wieght synthetic braided AN line for the low pressure side and stainless on the pressure line for safety. A peterson Vacuum regulator and new breather set up had to be fabricated to control the engine vacuum generated by the massive new oil pump down to 14"Hg. The vacuum pulled by this pump eliminated windage and gave us a nice Hp gain as well. To drive the pump, an adapter was made to reuse the factory crank pulley, but since I had saved money on the system I opted to go for the full ATI underdrive super damper setup Sam has to help out with high rpm crank vibration as well.
For cooling I decided on the GTM 70mm radiator and reusing my OEM fan assembly as well as a flush and switch to the nissan blue coolant, simple and effective.

In order to never worry about the clutch hydraulics it was decided to replace them with all new race worthy components. GTM came up with a Tilton racing hydraulic release bearing setup, with a new tilton large bore master cylinder for lightning fast clutch release and engagement and to make it so other people don't want to drive my car haha(it's really heavy). While I was in there I opted to go for an OS Giken Grand Touring twin plate as well to cope with future abuse, and a GTM bolt on clutch pedal stop to shorten my shift times.

After Dynoing the car with the above it was decided that there were serious exhaust issues and air was backing up in the engine(as well as my head gasket had blown) so to free up the breathing a set of JUN 11mm lift 282 duration exhaust cams was installed and a set of Z1 headers was ordered and modified by GTM for the car with VHR flanges to work with the existing GTM resonated test pipes.

To support the higher fuel demands of E85 a set of 600cc injectors and a Walbro 255lph pump was installed to work with the new rails and modified returnless setup.

After that I pulled the car out and got some Nismo's, and worked on the suspension while I waited to get it tuned, which was decided to be done at Specialty Z. After talking to Seb and leaving him the car Uprev was flashed and final tune results ended up at 361whp/290wtq on 91octane and 371whp/296wtq on E85. Torque is plentiful on both fuels with E85 having more than 275lb/ft available from 3500-6500rpm and with horsepower continuing to build past 8200rpm. For the graph the Green line is stock, the Dark BLue line is average bolt-ons the red line is E85, and the blue line is 91oct

Was this a 4th or 5th gear pull? anyone know

1slow370 06-29-2018 09:40 PM

they should all be 5th gear, also its for sale if anybody is interested its in southern ca and i can put you through to the owner.
