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.

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.

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. :(

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.

rofl, im more of a pictures kind of guy myself.

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:

      Nah, it's not the reduced knock margin. It is a direct mechanical effect of having to initiate the combustion earlier, while the piston is still rising, which starts to exert combustion pressure on the rising piston earlier, making the rest of the engine work harder to finish driving the piston up to TDC where the combustion pressure stops being a negative and starts being a positive. Your modern engine that only needs ~10° to make MBT doesn't waste the other 10 or so degrees of crank rotation. That's almost all of it. The difference in knock margin might go either way. Remember that modern engines to which you are currently comparing the long tractor engine (the RB) are now running super high compression, direct injection, tricky cam control and maybe even cylinder pressure sensors. You're not comparing apples with other fruit. It's apples and sea weed, or some other evolutionarily primitive vegetation. And remember, squish only really comes into play at the very end of the stroke. It certainly does good things, but it is not the biggest contributor to what's going on. It is quite possibly much less important in 4 valve head than 2 valvers also, because there is so much less squish available to a 4 valve anyway.

      Food for thought, a longer stroke motor would need less ignition timing vs. a shorter stroke motor requiring more ignition timing.

      Thanks Duncan, HART is only 10 mins from me (I did my bike license there), it'd be awesome if it ran these types of things.  Sutton Road does look good and they take fewer cars than SMSP which is good.  Surely you have enough land to lay a few million tonnes of concrete and some sprinklers D?

      I thought an engine that needs more ignition timing to make power is going to result in less power due to reduced knock margin? More time for the combustion to propagate -> more time for it to heat up the rest of the mix to detonation.
