Isuzu G-series Twin Cam

depends if your going to run a cat for engineering wether it high flow or normal and if you run straight through mufflers.

when you get a chance post some pics up.

6500 i found with all of mine power drop off befor then anyway.
So its all going nut161 whats it like how'd you get it going?

looks like a solenoid probably lets water into the heater when it gets to temp. what are you trying to do. i jsut blocked everything up.

you could use the old shims but id get a few thou extra on the cam and machine the existing shims down. i swapped a pair of standard cams for standard and had to get the shims machined to get the valve clearance right. the problem with billets is getting the worm drive that turns the dizzy on the ea...

toyota 18rg buckets swap out there abit longer and harder material and im pretty sure the shims interchange but nothing 2mm thicker than the standard g-w

that is what they are but they dont have a hole. i thought so too. any machinist cant machine them down from larger ones but for some reason i don't know they don't make them. ive got a spare one i could mail you to see if your mate can make them a coiuple mm thicker.

good work those figures sound a little bit high but only a few kw's. deffinitley change the throttle body. if you've had a chance to look at it you would of noticed how pathetic it is compared to the rest of the motor.

they change the whole profiloe of the lobe so even the spots whre the valve is shut it could be up to 2mm smaller. so you put a 2mm thicker shim under the bucket and on top of the spring. this is a preferd practice because your using the original metal on the original bucket so there is no compatabi...

yeah it sounds too cheap specially when you hear so many different stories. the one thing everyone says is dont re-weld the cams. i dont like the sound of bits of metal breaking off inside my motor especially around the cam bearing area.

i called wade cams today they can regrind the standard cams to any profile and you put larger shims under the buckets for $180 trade bit more for general public. sounds abit to good but ill be looking into it further.

no they aren't i havent seen an original ive had 4 motors and they have all been different.

found some info on cams a guy in sydney that builds rally twin cam's has a few different grinds. the problem is if you weld the cam and get it re ground it wont work with the standard buckets you end up braking the weld off so there is 3 options chrome the isuzu buckets, works sometimes. replace the...

a g200z is a single cam but if it says twin cam they could be the alright

dellortos sold all other parts will be sold individually. still have the custom inlet manifold.

thats what i did temp gauge.

id be upgrading the fuel pump. also if the popping is on cylinder 4 that's generally where the brake booster line is. have you got a fuel pressure gauge on the far side of the carbies that will tell you if your fuel system is adequet. even a cheap plastic one for diaginostics. do as much as you can ...

the popping could be an air leak on that runner and what fuel system are you running

yeah they rev pretty well. the zzr dash has the redline set at 7000 rpm.
If you are going to mod it the first thing i would be doing is upgrading the throttle body its the most restrictive part of the inlet tract. How did it sound?

G200wa it has 3 angle valve job mild port and polish, copper head gasket o ringed block spare o rings custom inlet manifold twin side draft 40mm dellortos match ported manifolds facet lift pump polished tappet cover and timing cover. forward facing oil filter modified for oil cooler, anodised fittin...

i keep hearing about these L1 cams but what are the specs, has anyone got them or used them and can you buy them or is it just a grind spec.

if your going all out ive got a bare 1.8 block and head no valves or springs and the crank needs grinding.and ive also got a crapper that i found out has been sitting in the rain for 5 years with the head off it looks like the pistons are rusted into the block but i can probably russle up all the bi...

if they look alright put them in. aslong as they are the same size not oversize bearings.

when you assemble it take special care setting uo the chain tension. they sound great when these motor's are put together right but one i had, the chain had stretched and there tensioner couldn't take the play out of it and it sounded ordinary.

very feasible. the standard internalls are alot stronger than gemini internals so i wouldn't worry about the toyota pistons. standard comp is about 9 something to 1. so you could deck the block abit and get it upto 10.5:1 or 11:1. throttles would be bigger than 40mm less than 50mm what ever you can ...
