Hello everyone. Advice please.
I thought 7mge turbocharged engine and found that these engines have a problem of oil starvation in two cylinders. After that I thought put the 2jz-ge + installed on this engine turbine as 2jz-GTE its price is very high than the 2jz ge Who knows what is necessary for instolyatsii turbine?

Hello everyone. Advice please.
I thought 7mge turbocharged engine and found that these engines have a problem of oil starvation in two cylinders. After that I thought put the 2jz-ge + installed on this engine turbine as 2jz-GTE its price is very high than the 2jz ge Who knows what is necessary for instolyatsii turbine?

It's much easier to turbocharge the 2jz-gte due to it's lower compression ratio. Also, the 2jz-gte has oil squirters to cool the pistons, which also helps the engine to dissipate the additional heat associated with the higher turbocharged horsepower levels. Lastly, the 2jz-gte's head flow- especially the intake side, is superior to the 2jz-ge.

With regard to the degree of compression, is solved by replacing the pistons with GTE and ARP studs installed with the replacement of gaskets of 1.2 mm.
But on the GE engines and turbines installed once go and blow 1.5 bar, the head and the block is not changed? Or something usilevat necessary?
Or, you can not strengthen, change the piston to hang the exhaust manifold, turbo, left his native intake manifold, intercooler, injectors 630cc, and ECU just what I do not know. Something may be wrong, please tell me.

I agree the GTE pistons and thicker head gasket would *partially* address the compression problem. However, the 2jz-gte head's combustion chamber shape (together with the thicker headgasket) is *not* the same as a 2jz-gte head. The shape of the combustion chamber & piston is referred to as "squish area", and there's a science behind optimizing squish area to maximize combustion efficiency. In other words, slapping in a thicker headgasket does not completely correct the shape of a head that was not originally designed for forced induction. Your horsepower results won't be equivalent. Oh, and don't forget about the missing oil squirters in the 2jz-ge block.

I'm not sure what you mean by the word "usilevat". Apologies - please restate your question.

Of course, the 2jz-ge exhaust ports are a different configuration than the 2jz-gte ports, so a different turbo header must be used.

Also, the 2jz-ge ignition system is far inferior to the 2jz-gte's, so you will likely need to modify it if you want to run a lot of boost.

Does the 2JZ-GE in the MKIV run an oil cooler?

Well, well there is some turbo kits on 2jz ge engine for lexus gs300 and achieve some results. how they do it, as far as I understand it, most pistons and head gasket, or simply laying his head, and the unit does not conduct nor any reinforcements. (I respect your vyskazivaniya and advice, do not get me no true test for me is very vvzhno), I just want to know whether the engine 2jz ge, to withstand the installation of the turbine with the replacement of the piston head gasket gte 1.4 mm, with ARP bolts, replacing fuel injectors, fuel pump replacement on wallbro, (intercoolers, candles, intake and exhaust manifolds, it is understandable) and of course the ECU, but I do not know exactly what to order to uprovlyat all.

Probably yes - I'd wager it's the same as the Mkiv TT's water-oil heat exchanger.

Apologies, I do not understand the following (are you using translation software?):
- vyskazivaniya
- vvzhno
- uprovlyat
- your use of the word "candles". To me, a candle is a stick of wax with a string inside.

If I have interpreted your meaning correctly, then I believe you do have the correct set of upgrades specified. However, even with the 2jz-gte pistons and connecting rods swapped in, you will not achieve the same results as you would have with a 2jz-ge. The 2jz-ge's (non-turbo) ignition system, the 2jz-ge normally-aspirated head, and the lack of oil squirters in the block will still limit your results.

I just ask as Toyota deprived the 7M-GE (and the 1G-GTE) of oil cooling and with a N/A-T Sturbo should make sure that the stock oil cooler is at least present, if not upgraded.

Looks like I lost my wager:

Well, at least they're easier to add. The MKIII's setup just blows... air cooled and the cooler is on the opposite corner. I like the 2JZ-GTE and 3S-GTE's coolers so much better. I wonder if I could get a 90? adapter built to use a 2JZ cooler on a 7M.

Anyway getting back OT, I feel that some form of oil cooling is an important thing to add to a N/A-T.

Agreed! +1

Interestingly and in engines and in 7mgte 7mge as there is a difference in the lubrication system with oil. And it will affect the work dvigotelya need to improve the system?
Sorry for my english, I use a translator.

What is the difference in the lubrication system? Also if this is a 7m question, you need to post it in the MKIII forum... (the MKIV runs a 2jz, not a 7M).

It does get tough to follow and it's getting more difficult as we get more technical. They're talking with us in the MKIII forum about the 7M too. I think he/she is weighing their options and wanting to understand the differences in the lubrication systems of both the 7M and the 2JZ (GE vs GTE). We should see a post in the MKII section soon too. ;)

Sturbo, the lubrication system differences between the 2JZ-GE and the 2JZ-GTE are pretty much the same as the 7M. The GTE has a higher volume oil pump, an oil cooler and it has oil squirters. Other differences are the same as well: different intake systems, different systems for air flow measurement, GTE is lower compression, GTE has higher flow injectors and a higher volume fuel pump. (Please correct me if I'm wrong on any of this.) I don't know if they have different cams like the 7M.

The Japanese-spec 2jz-gte's intake cam was different than the US-spec 2jz-gte intake cam, at least in pre-VVTi years. Post-VVTi, I'm not sure.

Do the GE cams differ from the GTE cams? I may roll this up into the FAQ... Won't be much different from the chart posted in the MKIII FAQ.
