Im new to the lexus game and I know there are probably tons of threads on here about this topic but none actually answer my questions. My goal is 500hp gradually over time as I build and mod my car. I just need someone to answer these questions for me. Just give it to me straight up.

Question 1- Is this realistic with a gs?

Question 2- What would be the easiest route, doing a 2jzgte swap or build my 2jz ge ?

Question 3- If I do the swap will I be sacrificing any of the options my gs came with like traction control, the power/snow mode, etc. ?

 

A few 2GS have taken the 2JZ well above 400-500 whp and usually it's with the GTE from what I've been reading here. If you have the money, or the knowhow, it's probably best to go with the GTE from the get go, since you basically have a ready made engine, but I'm no expert on that subject so I'm sure others can confirm or deny that. From what I've understood the GE does need some upgrades before it can be boosted that high (head gasket being one of them obviously).

 

you're thread is going to get flammed like a soul headed to hell.

this is a preference as opposed to a better or worse. assuming that you have a vvti 98+ gs, your internals on the bottom end are weaker for boost applications. unless you're gonna open it up and put some aftermarket internals in there; you're better off getting a GTE swap and boosting that.

you need to use that search engine more effectively bud. just trying to save you an insult from others

couple of nissan sr-20s would pull a premium one week before race wars.

 

DJ, the question for you is whether you have to pass emissions or not. I have to pass it down here so, that's why I'm doing a V8 swap. I can get it through emissions. I couldn't get a GTE through emissions.

 

vvti 2jz-ge has weaker internals than a GTE, soo like stated above unless you're willing to do a full bottom end rebuild with new forged pistons, rods, etc. you will be better off finding a GTE swap. while you have the motor out its smart to do maintenance on it, check the seals, timing belt, water pump, and there was one thing that was said to replace because its a pain to get to once the motor is in... anyways, good luck with your build.

 

location says new york, i think they do need to pass emissions.

 

If you're worried about maintaining stock(ish) drivability and features, keep your GE. You can put a thicker head gasket on it and run around 380whp or so. You'll have to really baby the stock transmission - or build it.

If you want more power, build the bottom end (or drop GTE internals in it) and you can get around 450whp.

There are a couple guys running well in excess of your 500whp goal on NA-T setups. But at that point the motor and head are so worked over it doesn't really matter whether it was a GE or a GTE to start with.

 

GTE block has oil squirters (cool the pistons) and a factory oil cooler. An engine built for turbo from the factory will always be better than some cobbled together NA-T thing. Buying a full Aristo TT swap with turbo's is probably cheaper than trying to cobble something together too.

2 grand with transmission. You couldn't build up your GE to be even close to this engine for $2000. If I didn't have to pass emissions, this is what I'd have done.

 

Pardon my ignorance, but I'm assuming it wouldn't pass emissions (the GTE) because it's imported or because it doesn't have the same emissions control components we have standard in the 2JZ-GE from the U.S.? Would a U.S. spec Supra 2jz GTE work for emissions purposes?

 

There's 2 issues.

1 - Talking OBD2 . If the ECU won't talk OBD2 to the inspection station, it won't get through emissions.

2 - The age of the swap versus age of the car. You can't legally put an older engine into a newer car. This was is probably pretty easy to get around though. At least around here.

If I was going down this route, I would have tried to source a 96+ USDM Supra ECU for this swap. It talks OBD2 and was emissions legal at some point in time. So, I was thinking JDM engine and USDM ECU. I didn't take it beyond thinking about it though. The GTE is significantly heavier than the GE and I wanted less weight on the nose of the car, no more. The 1UZ is lighter than the GE and much lighter than the GTE.

 

If you're worried about passing OBD-II emissions (like I am here in Dallas, TX) you would be best served with a quality NA-T build.

I'm only running about 14psi right now and the thing is pretty ****in' quick. Turning it up to 18psi (GTE internals, built trans) in a few days with a re-tune. I'm sure it'll be a screamer.

All that and it will roll right through inspection with no problems.

If you have a way around emissions - or live somewhere that doesn't test - then swap all day.

 

i was thinking about doing a gte swap but it's going to be a daily so i'm kind of turning my head to get another GE motor and keep it stock. i don't know how well a gte will last driving it daily "conservatively." i'm sure it does but probably more maintenance than the stock GE. just my 2 cents. good luck to you.

 

I went with 2jzgte vvti in my Is300. On stock stock twins, FMIC, 3" Exhaust, and conservative tune on Apexi Safc-II I put down 355rwhp and I've used it as my daily for almost 3 years now.

 

I'm Gona be doing the same swap! But ill be using a manual boost control , boost gage, trans cooler, and of course I will be using a 3" piping str8 exhaust maybe with a resonator so it's not so loud! I want to try and run 17 psi!

What other mods did you do to get this working?
