Isuzu G-series Twin Cam

Hrm, do i get started on the trials and tribulations of my life? Perhaps another day in detail. Ex gf is causing me headaches, especially her and that fuckhead shes with. Doesnt bother me that much though, hes too scared to look me in the face so all is well for the time being. Living with parents =...

Id say his pulling his cock. Pretty sure the journal spacing on the 4Z series is completely different, plus youd need custom rods etc etc. Load of crap. I have heard of using 2T or 3T toyota pistons for higher compression though. If Mikey [Tassie ZZ/Z well Tassie now coz the f***head sold HIS CAR] e...

and his is a I-TEC manifold...

Thats what i meant, dont know why i wrote ECGI.

L1 cams are a high-rpm N/A race cam, no good for turbo

Multicoil would be well worth the effort in my opinion.

Nick-

Two main types, early and late. Early used either twin carbs or the forward-facing throttlebody. They also require a diesel crossmember as the oil filter sits where the engine mount should. Late model [what you have] has the ECGI plenum, oil filter at the front, bolts in, and from memory a different...

You dont need to rebuild box's, just swap the front half of the DOHC box onto the SOHC box. Easy as.

What are you asking for the G180 DOHC and whats freight to melb worth?

Bottom end bearings, both crank and rod on both G180w and G200w are the same as G200z. I beleive the piston rings may also be interchangeable.

PS. put a Petrol diff back in it [3.89 vs 3.5 for the diesel] and youll pick up a few more hp.

Peak power in standard form on the G180w was 6800rpm, on the G200w its 6400rpm.

Was 130hp at the wheels or flywheel? if its at that low an rpm your doing well..

Nick-

No the MAP sensor wont read boost and youll confuse the Delco.

Will need a MINIMUM 2bar map sensor [ie 1bar vac, 1bar boost], and the ECU will need retuning.

Nick-

Same as SOHC dude. When i get the rebuild book for the G200z im building ill pass the details onto you. It makes sence that the G180/200 DOHC rods would be the same as the G200z bearings, extra oiling hole no doubt needed for the higher RPM these engines would see. That said, the G series engines in...

Dude, the TPS you need depends on what ECU you need. You will most likely have to fook around with one off another car.

If the engine builder suggested it then thats fine. Its kind of like linishing except your doing it to the bearings instead. Might sound stupid eli but your not supposed to oil the BACK of the shell, only the part that comes into contact with the journal. Engine oil can work but its viscosity is les...

*smacks you over the head*

They are the same you idiot. lol

I read it all and i want more then a cookie because im about to correct you on a few things. -Fit and torque rods to crank -Change crank bearings, fit crank and torque Before you continue i suggest you go to the local library and borrow a book on engine building. 1st step Engine block bolted to engi...

The diameter of the shell is the same, the only thing you should be worried about is the differences between the bearing.

Worst case scenario eli and youll need SOHC rods. Not the end of the world.

Nick-

Theres a couple of options here in my eyes. Its possible that the SOHC top bearing shell can be ran WITHOUT impeding any form of oil flow. Keep in mind that the G161z and G180z only use the lower bearing shell as an oil feed - the G200z uses the top. Theres a possibility that the G200z bearings may ...

Im going to re-iterate what i sai that if Rick doesnt get it let me know ASAP.

If Daniel and Rick dont get it i want it. I assume its running and needs nothing much to get rego'd?

Nick-

Forward facing plenum is off a 117 Coupe

G161z and G161w - 82mm bore
G180z and G180w - 84mm bore
G200z and G200w - 87mm bore

my head's flowed to 230....................... shame my motor aint going! WTF what have you done to it mike? GET IT GOING MAN this is sounding better and better by the day. Sell the twin carbies, sell the zed and put quad throttle injection on it :D Eli, i meant that poor oil supply to the rod bear...

It depends on what you need from the car. The standard pistons will be fine with relatively low boost and spot on tuning - bare in mind that the DOHC runs fairly high compression standard and that it wont take too much detonation for the pistons to fail. Head flow is good, particularly when modified...

G180z gasket should be fine for G180w Pete

Because from memory theres only 3-4 of those DOHC VRS sets left in the country and they are about 150-180. Eli you cant use the G161 gasket because the bores are 75mm as opposed to 84 for the G180. Get the G180 SOHC gasket and give it a go. No you cant use just hylomar between the head and block. Ex...
