There is also the L76... Which is what is in the VE. You can normally get them at a good price.

I think L76 was VY, VE's had L98. I read somewhere where the L98 cylinder heads had better flow than the LS2.

L98 is the gun engine if you cam it. They have much better heads, manifold etc. LS2 has a better cam only.

L76 has Displacement on demand... was in the VZ's (With DOD turned off) and is in the current VE's that now have DOD...
L98 was in the early VE's without DOD.

DOD was for auto's only. And yes, I meant VZ not VY for L76.

Yeah true,

Hey Guys
LS2 is a better engine - In VZ it was rated at 297 Kw & In VE 307KW. LS2 is dearer to buy and the engine HSV use.
L98 used in VE 2007 -2009 is a good engine and rated at 270KW. Itis cheeper and no longer in production.
L76 VZ & VE is the active fuel management (DOD) engine & proably the cheepest to buy (They use different ECU'S) . It was disabled on VZ & Enabled on VE 2009 on.
L77 Is used in Model year 2010 and is E85 compliant engine but Hloden did not use E85 untill 2011.
All engines are usable as you proably will change the cam if chasing power & re-map the ECU if you dont choose an aftermarket one.
L76 & L77 Lifters are expensive (If they become noisy) as 4 cylinders have the valving & solenoids to disable cylinders.
I would use LS2 .But then LS3 (6.2L) is better again.
Cheers Chriso

Hi Chriso, the late 2010 series 1 VE I have is L98, maybe changed with series 2.

The main difference with engines as stated is the LS2 has a better cam ect, but the L98 uses the LS7's heads without the CNC porting or Sodium filed valves, and uses the much better manifold (LS7)that suits the heads. Over all if you are doing a cam change any way you are much further ahead with all the better top end that you get with the L98. But I would personaly go the LS3 because of the cubes and you get the L98 heads ect with them. Holmart Stock the LS3's ($7200 complete).

Yep, I agree. In an ideal situation go with the LS3 option.

Would love to go LS3. The reason I ask is I am planning a IPRA Torana. Regulations say no more than 6 litre engine. This is why I asked the question on which would be the better 6 litre, LS2 or L98. The L98 sounds like a good option with the better heads and manifold, especially with a cam and change of engine management on the cards anyway. The most I have done any engine is change the timing gear on an old 202 in a VK Commodore I had, so what I would need to do to get more HP out of the L98 i'm not sure. Any one have specifics???

Is the l98 a 6 bolt main cap?
Same block as the ls2?
Does anyone know what the heads flow?

Hey
All the engines mentioned in this thread(LS1, LS2, L76, L98 & LS3) all have 6 bolt mains. 4 in normal location 2 in the side of each cap
Im not sure if the production blocks are the same but L76, LS2 & L98 share the same part number replacement block.
There are many varibles in cly head flow and differences in heads & valve size between engines - to quote a figure.
Regards Chriso

The l76 is an auto engine and if u want to mod the inlet plates and lifters need to be changed.
Go the L98 it is a manual engine and are less expensive to buy. Be careful when buying a new one cause holden currently he some faulty cams in the engines. They are stripping the hardning off the cam after about 15,000kms.
We have done 5 the last week at my work.
All the ls2,l76,l98 share the same block. the only difference is on the l76 engine internals.
I picked up a l98 engine brand new from holden for $6,600 complete with clutch setup and flywheel. even had oil in it.

Hi Lee, I have allready bought an L98 from SRE in Perth. They have got a new cam in it, they have built an engine they got just over 500hp out of. Check out my build thread on the IP race car I am building.
