Your lucky it wasn't worse mate, I would get the oil pump checked, it most likely would be wise to buy another...

I'm contemplating ripping the engine outa my VL and sticking it into 1 of my other car's I own, a Genuine 1975 LX SS Hatchback, I've already spoken to the same engineer that's doing my Capri, I can run Motec, I dont have to run cat converter because of the age of the car, nothing like old school with a tuff engine...

I am lucky. I just thank god I didn't have to buy another crank other wise that would have been another $800 down the drain. Oil pump will be checked this weekend. If it's no good I'll buy another N1 as they're only about $250 now.

What's in the LX now JET? Would you drop the RB30 straight in or do a 25 or 26 head conversion? Would love to be able to run no cat. I'd run straight pipes all day everyday if I could.

Hey mate the LX is bog stock standard, well I tell a small lie, the mighty 202 has extractor's and an exhaust LOL!!

Engine is already twin cam, twin turbo, but if I proceed ahead I will be converting it back to a massive single, something like a GT42 or 45 for the street, and for ease of finding boost leak's....

Hahaha I bet she goes hard with that exhaust!

Fark that's a nice bay! What turbo's are they? I just stuck with twin low mount 2860-7's for response and because I didn't wanna spend big dollars on a conversion.

I'd love to have big twins or a massive single but it'd be lad city and sh*t house for track work.

LOL, yeah nah I had'nt been started it since 2001 it's been in storage in the bush on a farm, went there poured some petrol down the carby a few time's and she fired right up, decided I'd better bring it home and do something with it rather than let it sit, otherwise I'll never do it....

This is the old girl on her long journey back and damn didn't it drum up some attention...

I lost count how many time's people came up for a chat when I stopped in town's to refuel and eat etc....Some took pic's standing next to it etc, alot of mainly older guy's, saying mate I haven't seen anything this original and untouched for 20yrs or so, even got a few offer's etc...LOL!!

Im going to pretty much refreshen it up with fresh paint and stuff, but its going to look identical pretty much just with some wheel's and stuff...

Turbo's are Modified GT3540's, I would love to keep them but I dont think room will allow, so a big single it will be, in my VL I ran 9.4 @ 150mph on 22psi taking off like a slug, I think 60ft's were between 1.99 & 2.1, I can do that on pump 98 all day long, in fact I could cruise off the line and run between 145-150mph like nothing...

She looks in pretty good nick mate.

Not a fan of the complete factory looking cars but a nice set of wheels and a drop in ride height can completely change a car.

Those are massive turbo's to have as twins lol. Especially on a 3.0L. What's it like lag wise? I wouldn't doubt a low 9 second pass out of a motor like that.

Just got off the phone to Racepace to ask about E85. They said I could make another 40-50rwkw but I'd have to get bigger injectors, another fuel pump and a bigger exhaust. I can't justify spending another $1500+ though. I think I'll be pretty happy with around 300rwkw.

yeah 32. its makin 322kw atm. was supposed to go back for a higher boost tune but its more than enough as is. its a gt35 single, 6boost mani etc. its funny how it looks the same as my ford but the turb is on the wrong side :)

edit, and dont get an n1 pump mate. at the least get a new std gtr pump. n1 are about half the width of the stocker through the inner gear.

Sounds good. I'm guessing it's pretty easy to make that sort of power with a turbo that size? I only had 255atw last time and even that kept me occupied. I'd be happy with anything above that this time.

Oh I never realized that with the oil pumps. So I'm guessing I'd be using a less restrictive oil restrictor if I was going to use a standard pump as it wouldn't flow as much?
