Not A Skyline But Maybe Some Of You Guys Could Help Me Out?

If you can't make 600hp with almost 6 lts without a turbo there is something wrong .

Most stock engines make 100 hp per lt these days without a turbo and I can think of a few that make close to 100 kw per lt .

Get rid of the old pushrod donk and buy a proper engine, with the aid of a turbo you only need half the displacement to make your 600 hp.

current 6.0L HSV's make 307kW- that's a measly 68.5hp per Litre

"most stock engines"? you can count the amount of engines that do that on your hands, and apart from the Hondas, they all cost cubic dollars

there's no way in hell an OHV 5.8L motor can make 800+ flywheel horsepower and be something you'd want to use on the street without being turbocharged, period.

You will be running out of hands, ok not most but lots . Just about all jap bike engines will fit the bill here, what about a 1.8 celica, 1.8 rolla with the same Yamaha engine, the odd Nissan 1.6, a few Hondas, Lotus, just a few that come to mind and all the mega $$$ Euros .

You DON'T need 5.8lt turbos to make that kind of power, unless of course we are talking about 60yo tech as is the case with the Generals old donk.

i applaud the helpfulness of most of the ppl posting here. nice one.

Ive seen a GT42RS make 547rwhp at low boost on a 355 Holden V8. (was a VR ute....skids anyone!!!)

Used the primary pipes off the genie headers (2 piece). just reversed (right hand side on left bank and vice versa so the face forwards) with custom 2 1/2" 'up pipes and the turbo sat roughly where the factory air box normally is and ran a 3 1/2" dump over the top of the exhaust manifolds and a 45mm Turbosmart wastegate.

Response was pretty good aswell...maybe not spooling at 2000rpm but wouldnt be far off.

Or maybe follow the Gen-TT setup. They make some good power but the heads on Ls1's flow a lot better.

Either Way I hope your not gonna use a TH700!!!

we're thinking about cars ffs. any modern bike that doesn't easily better 100 N/A hp/L isn't worth owning

and we ARE talkling about 60y.o engines. 2 valves per cylinder actuated by push-rods is most definitely 30's/40's tech

I did say stock engines ( cars or bikes) and I gave you some examples of cheap cars....

60yo engine exacly my point , it shouldn't be around, it has no place in todays technology. Thats why I told him to get rid of it and buy a modern engine of half the cubes.

Hmm Pro-Stock Drag Cars anyone......OHV 400 Cube NA V8s that make well over 1000hp and run High 6 Sec Quarters

No Place huh

Whats The Record ET for sport Compact Pro-Rwd.....6.88

dude wants some help modding the car he has- not your opinion on weather he should buy a different car. TT late-model V8 Commodore will prolly make a much more relaxed daily driver than a Skyline anyway

oh, right- and what fuel do they run on again?

idiot

Here I am trying to help a bloke out and im getting flamed.....I Love SAU.....

But To Prove a point.....

Heres the top 8 list a recent pro stock round.

1. Jim Yates, Splitfire 2001 Grand Am, 6.862, 201.46

2. Kurt Johnson, AC Delco 2001 Cavalier, 6.865, 200.74

3. Tom Martino, Century 21 2001 Grand Am, 6.871, 200.23

4. Warren Johnson, GM Goodwrench 2001 Grand Am, 6.878, 201.76

5. Brad Jeter, 2001 Grand Am, 6.887, 200.86

6. John Nobile, 1998 Cutlass, 6.891, 200.20

7. Allen Johnson, Amoco Ultimate 2000 Avenger, 6.905, 200.53

8. Tony Gillig, Gillig Racing 1997 Cutlass, 6.915, 199.40

Anyway Im showing My V8 boganess here.

BTW the Fuel is 118 Octane.

But Anyway I say go the turbo V8 route.

And if your lucky some turbo Gurus will help you out with sizing. or give Garrett or GCG a call they will be able to help you out.

wtf point is there comparing fully-built methanol cars to street engines?

gtfo

Of course a late model Bommie will make a more relaxed daily than a line .... The more people that think like you the longer GMH will keep on making 60yo engines with pushrods . I have a 4WD wit 4 valves per cyl and no pushrods and the Yanks are still selling pushrod cars??? If we all think like you we would still be driving T model fords !!! Thankfully we don't .

[sh@un]

think like me?

for f**k sake this forum is going down the tubes

i've never owned a push-rod V8 Holden or Ford, and doubt i ever will

for the record- every review i've read of the 5.4 DOHC Ford V8 Vs the previous 5.7 LS1 rated the Canadian Chev motor better. Just goes to show even a 4V/cyl DOHC head can be an Epic Fail when you match it to a massively over-square crank design (apart from the super-charged version in the Ford GT)

the fact that people are still happy to buy 2V OHV engines (in monstrous quantities), and do things like- tow boats and drive at 1300rpm in 6th gear at 110km/h speaks volumes about the longevity of 'old tech' in real world applications

anyone else that wants to start a moronic argument with me is going to get E-flamed back to the bronze-age

[zebra]

Sh@un for the record i wasnt comparing fully preped race motors with street motors. I was comparing the pro-stock cars with the likes of Titan Motorsports 2JZ Celica, Gas Motorsports Camry-Dore etc.

But by the looks of it this thread is over.

[BLN215]

O.k i'll try and bring this thread back on topic.Thanks to the guys who are genuinely trying to help me out here,there are some great points to your posts.

Now a few facts about my set up,its a 355 fully built with Crankshaft rebuilders tuftrided crank/Eagle H-beams/SRP forgies with 9.2:1 comp/the blocks been decked,o-ringed and runs copper head gaskets with 4 bolt mains/heads have been slightly cleaned up with 2.02int and 1.65exh stainless valves (over the standard 1.94int and 1.6exh) and will have a custom roller cam ground to suit the turbo/manifold combo.It also runs a T56 manual box so hopefully it holds up to some of the punishment.

It would have been making just over 500rwhp on 10psi with the standard intake manifold and the vortech blower and was like a stocker to drive (benifits of the larger cubic capacity and FI is it doesn't need to be wild to make huge power) so i dont think 600rwhp on 14-15psi will be much of a problem with this old dinosaur once the new cam and intake manifold are put on.
