nissanman312 Posted November 5, 2022 Author Share Posted November 5, 2022 (edited) While waiting for the car to return from France .......still 😂 Should be home.next week finally! I have been keeping busy making plans on which way to go with the build I've been through many different thoughts on what to do. I was tempted to stroke it out to 4l but you can add 3k to the bill for that so I had to rein myself in a bit I was also tempted to flog the charger and do a mega NA build But I have settled back at doing a mega bomb proof build on what I have I don't necessarily want more power than what I had it was bloody fast anyway I just to be able to drive the car as hard as I like for as long as I like at the power I was at. I think I'll be switching from ecutek to a syvecs ECU aswell after chatting with Ian at Litchfield and Romain at Racecal this will offer much better control and potential to keep the engine safe. I'm also going to go to town on the cooling mods for the trying to keep the z cool I'm having Colin at creative aluminium make me one of his triple pass rads and I'll be doing lots of ducting to the oil cooler and rad to make sure they are as effective as possible So the parts list for the engine so far consists of Product #: dyHG-VQ37.96 Dynosty Pro Seal Head Gaskets. 96mm x .5mm VQ37VHR - Nissan 370Z / Infiniti G37 - Product #: jep321266 JE Pistons Nissan Nissan VQ37VHR 96mm Bore (+.50) 10:1 Pistons - Set of 6 - Product #: arp202-5801 ARP VQ35 Main Studs Z33 Z34 And ARP 625 head studs Product #: bouVQ-OPG-VHR Boundary Engineering Billet Oil Pump Gears, VQ35HR VQ37VHR - Nissan 350Z 370Z / Infiniti G37 - Product #: brcBC6224 Brian Crower Connecting Rod w/ BC625+ Fasteners - Nissan 370Z 09+ VQ37VHR Z34 - Product #: 13028-0708KT Nissan OEM Timing Chain Kit, VQ35HR VQ37VHR - Nissan 350Z 370Z / Infiniti G35 G37 Q40 Q60 Product #: appATI918584 ATI Super Damper Street Crank Pulley, Stock Size 5.5" - VQ35HR VQ37VHR - Nissan 350Z 370Z / Infiniti G37 Q60 - Product #: A0101-EY04J Nissan OEM Engine Gasket Repair Kit - Nissan 370Z 09-12 Z34 Product #: 13070-JK21C Nissan OEM Timing Chain Tensioner LH VQ35HR, VQ37VHR, VR38DETT Product #: 13070-JK21B Nissan OEM Timing Chain Tensioner RH VQ35HR, VQ37VHR, VR38DETT - Product #: WPN116 Aisin OEM Water Pump, VQ35HR VQ37VHR VR38DETT - Nissan 350Z 370Z GT-R / Infiniti G35 G37 Q40 Q50 Q60 FX35 FX37 M35 M37 QX50 QX70 - Product #: 13085-EY00A Nissan OEM Side Timing Chain Guide LH, VQ37VHR VR38DETT - Nissan 370Z GT-R / Infiniti G37 - Product #: 407737-13 Stillen 9 PSI Supercharger Pulley Edited November 5, 2022 by nissanman312 4 Quote Link to comment Share on other sites More sharing options...

nissanman312 Posted December 23, 2022 Author Share Posted December 23, 2022 Busy day today with massive thanks to @350Butcher The engine is out and ready to be stripped at some point soon Seeing it like this feels like it will never go again 🤣 but I'm looking forward to it going back together solid as an ox and ready to take the boost thrown at it watch this space 3 Quote Link to comment Share on other sites More sharing options...

davey_83 Posted December 24, 2022 Share Posted December 24, 2022 Got the boys on the job!!! Subscribed ✅ Crankcase breather vent to atmosphere I always thought was a bad idea as you get no vac assist? plus a misty engine bay. Ideal set up would be to plumb to pre supercharger, bit of vac and fresh air. Quote Link to comment Share on other sites More sharing options...

To be honest Dave I can't really remember how it all was Bennet set this up about 6 years and 40k miles ago when we installed the kit on this motor he did it as per his lengthy write up I believe 😜 I had 2 catch cans running which collected a fair bit of @*!# from the pcv within reason but the future plan is for something like this setup https://sohomotorsports.com/products/soho-motorsports-hr-vhr-catch-can-combo What is it you're suggesting plumb it into the intake ? If so I don't like that idea it would gum the charger up a treat Edited December 25, 2022 by nissanman312 1 Quote Link to comment Share on other sites More sharing options...
davey_83 Posted December 25, 2022 Share Posted December 25, 2022 I have no experience with boosted setups and if it's been running like that for this long it can't be bad. If it was plumbed into the intake pre charger via a catch can, you'd get both a bit of vac and wouldn't gum the charger up. Thinking out loud, the crankcase air system isn't closed loop. On idle the pcv valve is open (one per valve cover on Z34) which would create a vacuum in the engine, so there's another two ports on the valve covers with no one way valve allowing fresh air to be drawn into the engine. When the pcv valves are closed under throttle or boost, positive crankcase pressure can vent via the valve less ports. Under boost currently the crankcase pressures aren't escaping under the aid of vac. Quote Link to comment Share on other sites More sharing options...
nissanman312 Posted December 26, 2022 Author Share Posted December 26, 2022 I don't fully understand it all mate I was led by Bennett on the initial set up for boosted application The one thing I would like to do this time is have the ones that had filters on into cans that would be ideal I think. If I remember rightly it came down to packaging last time and the very limited space to put anything Theres no rush this time around and the engine bay might even receive some dress up 🤣 Quote Link to comment Share on other sites More sharing options...
davey_83 Posted December 26, 2022 Share Posted December 26, 2022 Yeah I can imagine, very tight on space in there. 350z used one pcv valve and one breather port, one on each valve cover. For the 370z, Nissan felt the need to double their efforts so used x2 pcv valves and x2 breathers crankcase pressure focused. I remember clearly Andrea Preuninger head of the GT department in Porsche, saying for the 991.2 they were able to increase engine performance and one of the ways was to reduce the oil pressure. So made sense in my little mind that having a handle on crankcase pressure, would also have an effect on oil pressure - more pressure/heat, less performance. Looking forward to the build though fella ✅ Quote Link to comment Share on other sites More sharing options...
nissanman312 Posted December 27, 2022 Author Share Posted December 27, 2022 (edited) A little more progress today it's to the point of opening up now. Exhaust manifolds off Intake manifold off Remaining coolant hoses off Fuel rail off injectors out Coils and plugs out I'll be sending the injectors for flow testing and cleaning before they go back in last thing we want is a injector ruining the new engine.

nissanman312 Posted January 8, 2023 Author Share Posted January 8, 2023 (edited) Bit more work done this weekend and we're almost ready for the machine shop I was hoping in a way to see a obvious failure but nothing was really apparent apart from little inconsistencies on the gasket as if the coolant and washed it a bit but that's clawing at straws. Hopefully It was just a case of what the yanks call head lift due to the massive cylinder pressures experienced when adding boost to a high compression motor. Once the parts are cleaned up a bit and the heads are stripped down it will go off for machine work and I'll have the block checked for any cracks etc but on visual inspection it all in realy good order. But as for the rest of the engine it's all in realy nice condition which is testament to a good calibration from Litchfield and excessive oil changes and maintenance. so if you're thinking of boosting and if it ruins your engine the answer is no just don't ad to much boost 😂 So enough waffle here's some pictures Edited January 13, 2023 by nissanman312 3 Quote Link to comment Share on other sites More sharing options...

nissanman312 Posted January 9, 2023 Author Share Posted January 9, 2023 In a bid to keep the z cool with the new motor I thought a nice rad upgrade wouldn't go a miss. I had previously ordered a mishimoto rad as it keeps the AC but the quality didn't look the best so I opted for koyo and will have the stock AC condenser mated to the koyo The welds on the koyo are much tidier than the mishimoto for a start so that a good sign some care was taken in the making of it There will be a little trimming involved here and there but at this stage we are far from stock configuration so it's all about what works from here on in Heres some koyo porn 4 Quote Link to comment Share on other sites More sharing options...
nissanman312 Posted January 16, 2023 Author Share Posted January 16, 2023 (edited) The main box arrived today the heads are stripped so it's time for the machine shop these rods should take some bending 😊 Edited January 16, 2023 by nissanman312 2 Quote Link to comment Share on other sites More sharing options...
