V8 twin tirbo 33 skyline.

[Guest Miles B]

That sucks.. what happened to it? Doubt it would have overspun at 10-15 pounds... This is something I am worried about.. buy a brand new big turbo and destroy it.. Oh well, ball bearing CHRAs aren't that expensive

[B6Tmeteor]

Speaking of turbo v8's...

Good son of rajab!

Miles,

Remember that the turbo had been on the 2JZ when he had been running 2bar with insufficient fuel.

[Guest Miles B]

Ahhhh.. that's a hot turbine.

[GTS-t VSPEC]

Yes, the owner didn't realise the engine was detonating almost all the time it was on boost, so now the car is being rebuilt stronger.

[Guest Miles B]

Any updates? Can you tell me about the head gasket? Is it copper or steel? How much was it?

Any developments on tuning or approx power numbers / boost levels?

[GTS-t VSPEC]

Miles,

It made about about 400rwhp with the T78 before it packed it in, still waiting for the guy to get another turbo.

I'll check on what head gaskets were used:D

[Guest Miles B]

Much appreciated

[GTS-t VSPEC]

Miles,

On the drag car it has copper head gaskets and a o-ringed block. We got the gaskets from over east, about $150 each. It's making about 1200rwhp and pulled 8.59sec pass. Hope that helps.

The drag car uses two 700hp turbos' running a conservative 1.5bar atm.

[Guest Miles B]

Cool.. any details on who made the gaskets? I need to see if I can get steel ones, as this car has to run on the street too.

[Xeron]

sorry guys, i didn't check this thread for ages. That 1000hp v8 is a big block chev, 555ci, running petrol, but 110ron+mon/2 leaded fuel, so yes it aint a street engine

And the chev small block came in many many forms, as small as 4.3l.

[GTS-t VSPEC]

Miles,

I'll see if i can find the source of the gaskets for you.

Hey Miles B aka Fred Smith,

Hello everyone, first time in this forum. Greeting from the United States. I have done some to my car recently (6 months ago). With 8 psi my car achieved 324.5 rwhp. Currently, my spare engine is being built as we speak. The 1UZFE will be getting JE forged Dish pistons with 8.0 to 8.5:1 in mind. Some valve work and along with O-ring the heads and groove the block with copper gasket and ARP head studs. We are aiming 20 psi and shooting for 600-650 rwhp.

The limited for this setup will be the transmission and the RB25 turbos. This will be a daily driver with two baby seats behind. If you need more information, please visit www.lextreme.com

I will be shooting for 11 seconds this summer.

How much is one of those Wolf 3D Version 4 in AUD?

[GTS-t VSPEC]

Hi Lextreme,

You can buy the plug'n'play for about $1400, and the normal one for about $1200.

bit of random info on the lexus v8.

my father has one which was done in a track racing jet boat. because basically the dollars stopped we never ended up getting this to run its full potential. but we were close.

on this engine these are some of the things we did (from memory so some of the details i forget)

the block had the holes for the head studs drilled and helicoiled for larger head studs

custom forged pistons. 6:1 compression ratio

custom cams 630 lift nearly no overlap

custom intake manifold

2 x 2.5 litre super chargers running 2 or 3 x the speed of engine

we used heater elements in the intake manifold running fresh water from the under the boat to cool the air.

we were running to barry grant carbs (we couldnt get big ennuff jets to flow the fuel we needed so we got the smallest drill bits and drilled some out to stop getting det)

standard crank

standard rods

we only ever had this engine on the dyno once and got 900 horse power (6000 rmp) . cant remember the touque. at that time we only had 14 degress advancement. when we stopped working on the engine we had the advancement set on 32 degress. no dett what so ever. in a 50 second run it would drink approx 9 litres of c-16 racing fuel. we were running cold water from the track straight thought the engine yet still after 1 min we would have to leave the boat 15-20 mins to cool down as the super chargers were getting too hot.

the lowest we could idle was 1700 rmp.

we used carbs because it was easier than trying to house 24 injectors (which is what we calc we would have needed at the time)

this engine also has a HUGE solid al pulley on the frount which would have to weight 1-2 kg. i mean its two inches think. that would bring the dyno horse power down due to having to spin that thing up.

also we were running 40 psi of boost.

guessing by the size of the blades (in jet unit) we were running compared to others whom ran the same size that had has there engines dyno'd we could only presume that we were producing arround 1200-1400 horsepower.

some of the things that needed to be re done to inprove performance

extractors - they were made by some aussie f#$@ head who thought that a little 4 litre engine only needed small pipes. we were going to make a set that 2 1/4 inch pipe from each port running into 3 1/2 or 4 inch extractors.

a new manifold was going to be made to house meth injectors.

and we were considering a psi corp super charger.

the engine is sitting in ma workshop in a frame that who knows what my crazy father is really doing with it.

if anyone wants pics i had a camera phone but no digital camera.

im really suprised u couldn't find jets large enough for twin barry grant setup, any idea what cfm rating the carbys were? Hell u should have been able to get enough fuel with just 1 of the ones, let alone a twin setup.

Those demons are a mean carb.

[MattyB]

1125 cfm.

from mem.

you ever heard of a engine that uses 9 litres for 50 seconds?

[ricknismo]

Put on hold due to money.
