VH45 can take some boost. I know of a supercharged one. It runs no cooler and only aquamist injection. Its a real screamer considering its still in the Infinity.There is talk of a Z box fitting these.....maybe
The same block is used in Indi and also for the R390 + 391 Lemans car. Destroked to 3.5L and running twin turbos.
Take a look around the web for engine specs of this.
Type: 4494cc EFI DOHC 32 valve V8
Power: 208kW @ 6000rpm
Torque: 400Nm @ 4000rpm
Gearboxes: RWD 4-Speed Auto
Source: 96-97 Infiniti Q45
Twin Turbo V8
Valvetrain DOHC 4 valves / cyl
Displacement 3495 cc / 213.3 cu in
Power 410.1 kw / 549.9 bhp @ 6800 rpm
Torque 637.2 nm / 470.0 ft lbs @ 4400 rpm
Bore 85.0 mm / 3.35 in
Stroke 77.0 mm / 3.03 in
HP / Liter 157.34 bhp per litre
Gear Type 6-Speed Sequential
That should keep you busy for awhile

so u reckon the lexus v8 is better for taking boost?

Actually I think the Nissan engine will outperform the Lexus
But if your not going to decompress it then go with the Lexus. If you want horsepower go with the Nissan
Did you read about the big HP drag motor ?

well they are both 10:1 compression
tho can the lexus one handle boost better?

Drop the comp and use the Nissan
I believe its a stronger engine

how much would it cost to drop the comp?
cause we didn't want to spend to much money on internals mainly on tuning
we are using a sm2 autronic tuned by ray hall
we only wanted to run 6 - 10 psi thought twin vg30det non ball bearing T03's
with a 800x250x70 intercooler
do u have to change the compression? or can u still turbo it with 10:1 and just run low boost n good fuel
I don't have a barrow to push with either engine, but the 1uzfe has a lot of nice internals (forged pistons, nice rods and very nice crank) how does the nissan stack up.
I would be cautious with the indy engine/nissan engine comparo too, I doubt if any parts would interchange, same for the LM engine.
What are the physical dimensions for the nissan engine?

i might stick with the lexus V8 cause i know it is a tuff engine and stuff
and it is alot smaller then the vh45 and i need room to mount the turbo's
so i think i am going to go with the lexus
Hey guys im trying to identify the year of maufacture of a VH45, i need a 1989-91 model VH45, the only thing i know of this particular engine is its out of a G50, i guess the question is what year did the G50 come out??

have you taken a look at a vh41. As far as I can tell, it is very similar to the 1uz. makes about 190kw in stock form and i know a dude who is about to twin turbo one
let us know how it goes when he gets it all running.

I do know the VH45 is bigger thanthe VH41.. deck height is different.
The VH45 has 6 bolt mains.. not sure on the 41.

Please check out this thread.
"Plastic tension/guide bodies....good one . Problem can be fixed with the later model tensioners, but not cheap and the parts are hard to get in Oz. Given that the early motors are (apparently) the ones to get from a performance POV and most likely are the ones available to us in Oz, it seems it could turn out to be an expensive conversion in more ways than one. There's also no way to find out from an external inspection if your engine has the problem."
This is a very big unknown on the earlier units.
Do you have to pull down the motor to fix this?
I have seen the bottom end of both of these engines and they are most impressive there is a vh45 being built atm here in brisbane which is going into a 180sx. Pics when i visit him next.
find out what year the engine is if you can

As much as I'd like to get a cefiro and put a sr20 in it, the idea of a vh45 (over vh41!!!) sitting between the struts is pure wet dream material!
I'm taking it that this is possible, since you have other people chucking the '45 in 180s and r31s..?
A vh45 only costs ~$2200 for a front cut doesn't it?
