Mate I would be steering clear of the ITB Harrop manifold unless you plan on reving it (which it doesn't sound like your are). THis thing is just screaming for a harrop blower tho. The new HH112 blowers are good for around 400rwk on 12Psi of boost on a stock 5.7L with a flat torque curve.

We fitted smallish cam (220@50thou) to a 5.7L Elfin Streamliner - we then proceeded to supercharge it with the old harrop charger(HA122??) with about 10psi of boost it made a touch over 500rwhp in a chassis that wieghed a touch over 1000kg's. Let me say this thing is a missile and its so tractable because the torque curve is flat.

im looking at turning it to around 7000rpm.

next engine ill throw rods at for some insurance.

not real keen on a blower, it just seems like the easy way out, and besides, if this thing makes 400hp it will be potent enough. otherwise ill have traction issues etc etc. but i can guarantee you it will get a good rev.

love it mate. the car is looking awesome. there certainly are a lot of positives I can see in going the LS1 route as much as it may pain me to say it!! Can't wait to see and hear it running. ;)

Rob, have you used the intake on any car you have tuned and if so how did you find it?

Sold the go-kart over the week-end so cashed up and ready for suspension package.

Will be giving SK another ring during the week to get the ball rolling.

also looking at ordering front G4 brake set-up fromJust Jap.

looking forward to this stage of the project as it has stalled as of late. its all dollars at the end of the day. another step closer to finishing.

you and me both, project has been dragging on as of late.

speaking of hearing it, i met Gonzo aka Gonzos exhausts last saturday as we were pitted next to him. had a few drinks and listened to some stories as the night became next morning. He and his son crew the Toyota Orion 2JZ powered 6 second monster. They pulled some mufflers out of the truck that would blow your mind. Once the engine goes back in and i know what bends etc i need ill post some pics of these mufflers as they are out of this world.

hey Roy, as you know i have done the build from scratch including accident repair, some extensive panel work and paint etc. if you had a rolling shell with cage, suspension and brakes already done, and you were only looking at the engine/driveline conversion, you can buy brand new standard LS2 6litre for 4.5k, gearbox im not sure about but say 1500-2000. clutch, tailshaft, mounts, plumbing, exhaust, wiring etc. i would say 10-12k turn key. i reckon this thing will owe me somewhere between 30 and 35k now that i am doing the brakes and suspension which is roughly 2k a corner. it all ads up when you do everything. sometimes i think i should have started off with a better shell, but instead of paying 3k for the car i would have payed 6k. that extra 3k payed for the cage.

Have been reading this thread from the start, top work. Have to ask, how much ball ache is involved? I mean give a car, engine and gearbox, what would be a reasonable figure to budget for all the other stuff?

time will tell, she might be too much car for me, or it might be a nugget. SK has suggested to set it up for time attacks and track days for the moment so i can get used to it, so suspension will be set up for semi-slicks. probably will need to get someone with some experience behind the wheel to give it the score out of ten. and some feedback for set-up. thanks for all the positive coments guys. i know its a bit hard for the avid nissan ethusiast to swallow, but i couldnt think of a better car to build.

Yeh, I'm with Roy, and you too evidently Stu! I love it... just love it, and can't wait to see her lapping it up! :)

Its your car...if you plan on doing some track work then nobody better to get to understand what works and doesnt work then you. Perfect situation, you develop as the car develops....win:win :(

I would say majority of the people you throw the keys to wouldnt know any better then they guy with enough mechanical understanding to have built the car. Hell, read a book or three to arm yourself with a plan and go ahve some fun :D

I'm reading hustler's 100 tips for top sex at the moment. also quality reading. excellent diagrams too. I reccomend picking that one up. in fact they had one called "tune to win: how to land a smoking hot broad minded female" too.

Went too SKs today, everything is underway. Front brakes also ordered from Just Jap.

busy couple of weeks ahead.

Glad to see I have a fan, I wrote that article. My alias is Dr Studley, master of moot :dry:

      R32 GTST - 600KW+ RB28/CD009 Build

      By GTSBoy · Posted

      Yucky. Things haven't gotten any better though. Now you have Emerson and Honeywell pushing these massive DCS/Scada things with proprietary hardware. They're not a PLC, they're not a computer, they're a...distibuted PLCish/DCSish monster of thing, that only they can program because they make the barriers to entry for anyone else so fricking high. And their developers are all located in the third/developing world (and India, in case anyone does not include that place in that category) and there are terrible failings of the ESl variety, of the care and common sense variety, and f**king forget about Functional Safety. Not a one of them has any idea what it means to comply with an IEC 615xx series standard.

      Low oil pressure after WOT

      By pogman · Posted

      All of the ECU grounds are to the chassis, the IGN grounds are to the cylinder head and i believe all the OEM body harness are left in original locations, im trying to work out if i can tell if the sensor voltage itself is losing any power to it from the very low ECU voltage. But yeah a manual pressure gauge will help in picking which path to actually chase. Also please dont bully my wiring plan i never designed it to be universally understood hopefully it still can make sense to you, im a wiring virgin.  1 thing i have just noticed the pressure sensor in question relays both pressure and temperature, the temperature reading holds nice and steady despite the low ecu voltage but the pressure reading is the one that jumps around alot so maybe it is really a pressure issue? wiring plan.xlsx

      RB25DET Solid lifter conversion

      By Yeetus · Posted

      Gday, Due to not finding much up to date info on this topic I thought I'd make a thread to get peoples latest opinions/recommendations. Background info -  I've got a S1.5 R33 GTST as a fun project car, mainly for street use and occasional drag strip, apart from all the cosmetic things I'll be doing a full rebuild of the engine with forged internals. Since it'll be getting new cams (kelford) and springs to match I thought I might as well get new lifters and valves while I'm at it, the dash says 160k KMs but the engine seems pretty tired, compression measures about 130psi across all cylinders so I'd like to freshen everything up. This is where I'm tempted to just fork out the extra and go solid lifters while it's all apart, aiming for 400-450kw atw with a flex tune. Assuming all supporting mods (oiling, fuel and all bolt ons) with a lightly ported head and turbo to match (yet to make a decision possibly gtx3582r or similar from Hypergear) I've seen the Tomei kits with just the buckets getting around, Supertech sells most things - Supertech High Performance Cam Followers | Trusted Racing Cam Followers Questions -  Has anyone found the Hydraulic lifters to limit them at this power level? Is it usually found that you can just clean the stock lifters and find they work fine?  Does going solid lifters save any headaches/issues with hydraulic lifters in the future? Any recommendations on other things that will need to be replaced, I know I'll need to get the solid profile cams but can you use the same type of valves and springs/retainers and is it recommended to change the guides and stem seals?    Summary -  Basically looking for pros/cons and wanna know if I'll actually need the extra RPMs from solid lifters or it'll just be bragging rights to say it ReVs OvEr 8000 Cheers

      Ha ha ha, this stuff they had was installing Toshiba PLCs that were made some time in the 1990s, and they were replacing GEM80 PLCs. To let those two talk (staged upgrade along a ~1.2km long building that was split into 4 sections), was a bunch of WinXP machines running Java gateways... There was no way to put something like ProfiSafe in... Most of the HMI machines were WinXP, with Java program, with a custom button board emulating a keyboard... About the only buttons in the operator stations that went direct to the PLCs was the eStop. There was some interesting design stuff in that place...
