Isuzu G-series Twin Cam

get your oil pump clearanced and rebuilt when the twin cams drop oil pressure the first thing to go is the exhasut cam bearings and that can be costly. can you post up the details where you got the head gasket. keep us posted. While your rebuilding it put an xf throttle bodyon the manifold the stand...

i hope you saved the old head gasket because it's totally different to the g series and is one of the parts that has to be made. to get the valves out you need a double over head cam remover. if you are using the old valves and cams make sure you label the shims that go under the buckets so you can ...

id be keen for a set of cam bearings but i have re-used them in two different motors and no-dramas yet. where did you get the vrs gasket set.

you could be right all the one's i have had just had standard 5 speeds with the twin cam bellhousing and i used the fine spline. if its the proper close ratio box that would make it an even bigger score.

1.tailshaft yes you can use it. 2.i don't know what they used if it's standard go either 2 1/4 or 2 1/2 with extractors or if it's got a manifold just match it to that. 3.i used a vl with a microtech and it was perfect. 4. bottom end bearings are the same as the g200z make sure they have two oil hol...

nizpro did testing on a ls2 with standard internals 10.9:1 compression with 20psi boost and pump fuel. it ran a 10sec pass.

your right they said you need good knock sensors and good tuning they were talking about standard ls1 commo's with 9:1 comp and big boost but you need to run good fuel all the time. engine builders normally build customer engine's on the safe side i know id hate to put a tank off shit fuel in and bl...

im still on the hunt for cam bearings.
I also read an interesting article in zoom magazine about compression and turboing. they were talking about unless your interested in dyno comp's and big top end number's people should be running more compression in there turbo motor's.

dont worry about efi you can get a manifold made easily because there isn't any water on the inlet side ive got pics then chuck some twin carbies on it and she's done unless your going turbo.

Im thinking of selling one of my old motor's what do you think it's worth. stock standard 1.8 twin cam missing dizzy cap rotor button leads, fuel pump and hasn't been started for 3 years . it has a standard 2l clutch but no gearbox, also has a crappy pair of extractors that are ready for the bin but...

on a good note, i got a new job in sydney paying heaps more getting away from the cold and the lesbians and i had a go at lining my interior with tin myself. I got quoted at least $200 just to cut the sheets after i made the templets so i had a go at it myself and it came up 99% perfect so ive had a...

thanks that will get me started and i can go from there.

If use are like me car's and there parts don't help any situation. Ive got one project ute at a mates house 3 years old. my twin cam at mum and dad's house 5 years old and my 2.6 tg with me. i moved to canberra to finish my last year of my apprenticeship but on trade wages on a hand shake. well they...

i dont know if your taking the piss. my flatmates think im a freak laying under a car at 11at night in winter so that would definitely confirm it.must be all the petrol in the blood.

thanks i thought so it's going to be hard to adjust once its in.
Ive got an auto gemini and im putting the manual with remote shifter in it looks like it will fit in the hole where the auto selector is anyone done this befor or do you still have to cut the tunnel.

how do you set the springs on the u bolts that hold the gear selector down.
tightened or loose?

I was talking to a guy that had a few twin cams and used to rally them. he said he had one with a 2.6 rodeo crank in it with the journals machined down. he had twin 48mm webers and was making 250hp, i dont know if this was at the wheels or crank but it's pretty impressive. the only problem was that ...

let me know how the emission testing goes im about to do the same with my 4ze1 stroker. i told the engineer it was a 2l with a 4ze1 head and its got twin 48mm downdraft webers. emission testing is done at penrith in sydney and its free. im going to re-tune it lean it out and retard the timing as muc...

i was actually thinking of cutting it and spinning it around for the exact reason you are thinking of,if i do it no intercooler and methanol short path should be really responsive. the inlet's of the throttle bodies would sit at the perfect height. ill get some photo's for you. yeah thrash it thats ...

Ive got a copper head gasket on my twin cam which sound very simialar to whats done to yours except ive got carbies and when the engine builder put the copper head gasket on he anneiled it. im not 100% but i think you heat it up with an oxy slightly to make it soft then torque it up. if you dont do ...

if your running an aftermarket computer you want need a wiring diagram. these motors electrical are very simple just get the wiring diagram of whatever computer you are running and re-wire it to that. injectors throttle pos sensor, temp, fuel pump and ignition wires and your done.

Just do the things you would normally do to a g motor to the twin cam. there are a few different versions but the bolt on bits are the same. You want a 2litre flywheel and clutch and lightened is better. how much power do you want to get out of it. i would also upgrade the throttle body it is very r...

sidedraft weber manifold for a twin cam $100 plus postage

are you after the standard fuel reg thats on the fuel rail or an aftermarket one. ill split a set of g180w pistons for $50 plus postage or the whole set for same. Are you getting forgies made if so i might be interested depending on what compression your going for.

Do you know what size in mm the bore is cause i think i have a standard set at home but they could be out of my 1.8
