Fulcrum2000 Posted October 10, 2018 Share Posted October 10, 2018 Hi all Is the actual block on a GE the same as a GTE ie are they interchangable? In the middle of a rebuild and can get a GE block easy but will it fit my 93 TT line a glove? Also are non and VVTI blocks the same? Link to comment Share on other sites More sharing options...
Mk4Gaz Posted October 10, 2018 Share Posted October 10, 2018 Ge blocks are the same, albeit without the oil feeds for the turbo/s, and no oil squirters for the pistons. They also don't have an oil cooler like the gte, but I'm not sure if one can be bolted on, or an external one is required? Link to comment Share on other sites More sharing options...
Fulcrum2000 Posted October 10, 2018 Author Share Posted October 10, 2018 I'm talking about just the part if the block with the actual bores in are they they same? Sorry if I wasn't clear Link to comment Share on other sites More sharing options...
Mk4Gaz Posted October 10, 2018 Share Posted October 10, 2018 So was I bud. The block is the same, but doesn't have oil squirters in the bores, or the oil feed holes for the turbos I'm talking about just the part if the block with the actual bores in are they they same?

Fulcrum2000 Posted October 10, 2018 Author Share Posted October 10, 2018 Sounds like it's a no go then cheers Link to comment Share on other sites More sharing options...
Mk4Gaz Posted October 10, 2018 Share Posted October 10, 2018 Not knowing what you want to do, it's difficult to say if you can make it work. But, you can drill/tap oil feeds, and run without squirters. Link to comment Share on other sites More sharing options...
Fulcrum2000 Posted October 10, 2018 Author Share Posted October 10, 2018 My bore is scored after years of some idiot storing it and then running it without a service. I thought if I just got a new bore it would be job done as the engineering firm sorting it are taking forever to get to mine Link to comment Share on other sites More sharing options...
Hemanhead Posted October 10, 2018 Share Posted October 10, 2018 Blocks are the same, obviously they have different rods pistons and the oil squirters but most built engines remove them I think as you have to bend the squirters as aftermarket piston skirts are different, as are the crowns the oil shoots at, so they probably don't work as intended anyway. Vvti blocks have a larger oil outlet to feed the vvti head I think. Not sure you could just overbore one cylinder? Link to comment Share on other sites More sharing options...
AC93 Posted October 10, 2018 Share Posted October 10, 2018 GE vvti blocks are weaker. GE non vvti has the same crank/rods, pistons are a different shape on top but are interchangeable. Just don't have oil squirters which is a debate on its own, depends what power you aim for Link to comment Share on other sites More sharing options...

and1c Posted October 10, 2018 Share Posted October 10, 2018 Pretty sure the blocks aren't any weaker, just the conrods. Yeah that. From what I've seen the castings are the same, just GTE have oil feeds and squirters but they can be added as mentioned above. It's better to use them IMHO even though forged pistons dont have the oil galleries in them like the 2jz gte cast ones, as it cools the piston skirt better than none.

Dave_Batch Posted October 10, 2018 Share Posted October 10, 2018 Blocks are interchangeable, speak to srd, they can drill the correct gte turbo oil feed to a ge block. Dont worry about the oil squirters Link to comment Share on other sites More sharing options...
SupraTRD_MK4 Posted October 11, 2018 Share Posted October 11, 2018 (edited) If you cant get a GTE block I would get the GE block. I haven't opened up my oil coked engine but hoping my crank and bores look okay to use. If not I will be buying a GE block as they are selling them at importers here by me for a 1/3 of the price of a GTE VVTi engine. I have seen a few GE motors turbo charged pushing out 800kw and over 1000nm torque. This is obviously with additional work. Many have spoken of whether an engine needs oil piston cooling nozzles or not. They are there only to cool down piston crown temperatures as they spray oil under the piston. The name speaks for itself. I don't know bout the GTE piston but it may have a galley drilled in it were the oil can circulate as it sprays in but I could be wrong. None the less if you push the motor to its max, that piston cooling nozzle will not cool the piston crown adequately enough any longer as combustion temperatures would increase hence people remove them. Aftermarket pistons for GTE engines in most cases do have the cut away for the nozzle.
