Hey all! I know I kinda fell off the face of the earth right before I began modding. Unfortunatly I got a new job that has me working alot and on top of that my computer broke so i've been using a old Imac.

Well the past month(s) have been pretty ****ed up. From being ripped off from buying (or at least trying to buy) the WALD kit to my back window getting knocked out its looks like i'm back to square one again.

I went ahead and placed a order for the WALD kit from that site I saw www.jdmlexusparts.com so I hope for a speedy delivery. As for rims I still can't decide which of the 2 Club Linea wheels to get but I'll figure something out soon.

As for my big plans for 2jz and everything most of it went out the window (actaully the window went in) when 2 guys I went to school with decided to smash out my back window with a broken board. After everything that happened for a while I was looking for a 98-00 GS4 to just buy and leave stock... but I just can't bring myself to part with my car.

Now i've been looking around for a new plan and I've been seriously thinking about a 1jz-gte swap. From what i've researched (correct me if i'm wrong) its a great engine just like its predicessor except that it can't handle as much power as the 2jz. However, i'm only looking to run 400 or so horsepower so though I'd loose the torquey 3 liter 2jz i'd cost me a fraction of the cost of a 2jz-gte swap. Has this ever been done before? (is it even possible) I don't know of anyone with a GS3 with 1jz but I do know of alot of supra's/sc3's have done it.

Also, i'm kinda boost retarded and I was wondering if someone would clear something up for me:

If I were to use a 700hp turbo upgrade kit on the car could I adjust the boost so it would only be around 400hp? Or would I have to do something else?

also:

If my car is a 4spd automatic can I put a 5spd auto tranny in it or no?

Well its good to be back and i'm ready to start the modding process all over again!

 

Welcome back!!

Sorry to hear of your unfortunate incident!

The wald kit is really nice and I can't wait until you have it installed!

You can always control boost with the "boost controller". The reason people blow their engines is that they over boost and that is what causes it. If you ran 400-500 hp that is good enough.

It is going backward IMO. The 2JZ-GTE is a common upgrade with known issues. Obviously it may not have the uniqueness factor of the 1JZ...how about a 4.3L swap.

 

Damn its good to be back. I only have a few friends who are into cars and this place was somewhere where I could actaully talk with other people who felt the same way as I do about lexus (especailly the 1st gen GS) Luckily the computer situation is fixed (along with my window ) so as I said its back to modding again.

I was thinking about a 1uz-fe but I just don't think it'll fit. But if someone knows something I don't I will jump on that instantly.

The other thing is.... is it possible to drive around with like 5-6 pounds of boost then on the highway up it to like 8-9 (whatever 450-500hp is) cause idealy thats what I would like to do. In minnesota there are ZERO ferraris, supras, and the like... however there are alot of nice cars around (lots of pharmasuiticals in MN) lots of S4's, RS6's, SL500's, M5's, tons of 911's, and a handful of M3's. As long as my little old lexo can beat that bajesus out of the most of them i'll be happy I'm not into racing at all but I do like going (responsibly) fast, and I happily await beating the punk kids who's parents bought them there [insert nice car here]

Also, I've been searched everywhere but I can't find anything about a intercooler fitting the stock bumper cause as you know the WALD kit is a front lip that uses the stock spoiler.

 

Someone correct me if I am wrong but while the car is in motion you can set the boost. As soon as the car reaches a certain rpm, you will have all that power!!

 

good to see you back brotha

 

I'd probably stick with the 2JZ-GTE, the Supra stuff is available. Perhaps some ofthe other guys from the second gen can provide more details on how they did their up.

 

I totally agree with RA40. You do not want to go any lower in displacement with this car. It is a heavy car and should have come with that 4.3 v8 stock. I would say turbo 2jz-ge, 2jz-gte or if your nuts the 4.3 liter v8 from gs400. But if you go that route you might as well be the first to try a chevy small block v8

 

If you decide to turbo your current engine or a 2jzgte, check out the SC forums because quite a few people over there have exerience with turbos. Also check out http://www.supraforums.com and http://www.mkiv.com/main/index.html

 

I want to go with the 2JZ but the $4,400 for the engine and countless more dollars for install is out of my reach right now. I found a few 1uz's for $1,100 and if i knew it was possible or done before that is the path I would most likly choose. There is a excellent place in town that I know is more then capable of doing the swap... if its even possible to be done.

 

Some of the down under forums have a wealth of info and it is likely there is a first gen Aristo stuffed with a 1UZ. Toymods would be my suggestion to look around.

 

Here's my .02:

The 1jz would definitely be an interesting swap do to its rarity. However, it would be quite difficult to find parts for it should anything go wrong. I'm no expert in 1jz, but I have worked in auto parts and Toyota replacement parts are hard enough to come by for popular US models. Now if money's your main concern, then it would appear that the 1jz would be the better route (considering you've said you've found it cheaper). It's true it will give you lower torque, but that will be negligible if your upgrading the turbo system.

As for the turbo, I wouldn't got with a turbo rated for a high output and then de-tune it. Each turbo is engineered to operate at its highest efficiency for whatever rating their given. Besides, most high horsepower turbos do cause significant drag at the low end. On a street car, this would be very undesirable. If you want 400hp, then get a 400hp turbo. It'd be much more efficient than just whatever's biggest.

As for the tranny, I'd recommend getting your auto fully built. Any stock auto is gonna suffer under high output stress. Automatics are great for turbo, just as long as they're built to handle the output.

I'd stay away from a 1uz swap. First, it's a heavier engine. Screwing up the physical properties of a car is always dangerous. Sure you'll be able to go straight real fast, but when you have to turn or stop all that extra weight in front is gonna confuse the heck out of your suspension and braking systems. Plus you'd most likely have to get the strut towers notched with means even more money.

Hope that opinion helped.

 

After giving it some thought I figured out the following things:

The 1JZ dosn't have enough torque to carry the car the way I want it.

The 2JZ is out of my price range and has been done 1,000 times before, and as with the 1JZ getting a big intercooler in the stock bumper is going to be a *****.

The 1UZ is in my price range and has possible not been done before, it has the torque and HP I want at my finger tips instead of waiting for the turbos to spool (unless i'm wainting for the turbos on the 1UZ to spool )The weight thing was a very good point I never considered. However I remember reading somewhere (I hope someone can back me up with this) that the 1/2UZ-FE's are aluminum blocks so they weight just a tab bit more then the 2JZ's. Also a thing to consider is the 100+ pounds of stero equipment in the back is not going to help with weight distrbution thought that weight on the wheels will help the car stay on the road. Also Supra brake's will help stop it too.

Tranny rebuild is a must. As for wheels I decided on those 19" 2 peice club linea wheels. Although I'm not sure if 19x8 in the front and 19x10 in the rear will work. I think the rear may be too much wheel.
