[mikes_classics_68]

Supras only come with an inline 6. You've still got plenty of options though. Theres the 7M (America) 1JZ ( Japan) and the 1GGe...something (Europe)
If you wanna get something newer theres the 2JZ from 93+ supras.

If you want my input I personally like the 7M, Its got decent power and is way easier to get parts for then the others.

The concept supra is rumored to have a V-8 or V-6.

[mikes_classics_68]

really? thanks yeah i have seen them advertised with v6 engines and some with straight six so i wasnt sure, most the ones i see in adds (ebay) are LHD i assume the 7m engines? is there any way to tell which engine it has? and i have a friend who works with cars and he said he doesnt like supra's cus parts are crazy expensive,but like u said the 7m are cheaper but are they still a arm? i am looking at getting one and hopfully getting it to the 600 to 700 hp range (no need for the crazy 1000+hp, how much money in parts would this take? i'm also looking for one 93 and up. thanks again

If your getting a 93+ (MKIV) its a 2JZ with N/A, Single turbo and Twin turbo variants.

If your only looking to make 700HP though Id go with an MKIII Supra turbo. With the 7MGTE engine. You can pick the car up cheap. Usually around $500-$1000 with some engine work needed, but you wanna do a rebuild anyway right? Parts and mods are easy to find for the 7MGTE and wont cost you an arm and a leg to buy. The stock transmission is also very strong and wont have to be changed.

Im not sure about the exact price to make that kinda HP but there are a few guides around the internet.

The MK IV(93-98) the only came in non-turbo and twin turbo configuration. Single turbo cars are after market jobs. The turbo came with an LSD. The NA has an open diff. Expect to pay $14-$18 K for a non-turbo and $18-$22K for a turbo car. Anything cheaper is probably a scam. Always ask to see the car and title in person. There are a lot of MK IV internet scams. Parts for the MK IV are rather expensive as compared to a GM or Ford.

A cheaper route is a MK III(86.5-92). For a car in rough condition the price is arround $1000-$2000. For a well maintained clean car prices run about $5000-$7000. The head gasket in 7MGTE is a well known weak point. It should be replaced with a metal head gasket if it has not already been done. The NA came with an open diff. The turbo model came with an LSD. The AT in the MK III is not a good choice for high HP. The R-154 5 speed is the tranny of choice. You should also consider an after market LSD that will hold the power. The parts selection for the MK III is limited due to its age and limited popularity.

One option for the MK III is the 1JZGTE swap. It is the older smaller version of the 2JZGTE(2.5L instead of 3.0L) found in the MK IV. It is a decent engine if you are looking for top end power. Because of it smaller displacement it has weak bottom end power. It is however a short stroke motor allowing for a higher red line. Parts for it are hard to find in the US. The accesories,such as PS pump and alt, and service parts, such as plugs and oil filter, are the same between the 1JZ and 2JZ. Other parts such as pistons, cams, turbos, etc are not cross compatible. You have to import parts from Japan or Australia.

yeah there are alot of scams on ebay as i can see there are a few potentialy good deals, also the twin turbo and the non turbo, is there a dif other then one has twin turbos and the other doesnt? wouldnt it be worth it sense your prolly gonna upgrade the turbos anyways to just buy one without them and save the money? or what, inlighten me, i'm new

[TcmaBoy]

If you want a turbo car you have to start with a trubo car. The NA has 9.6:1 CR pistons. The turbo car has 8.5:1 CR pistons. The stock bottom end in the turbo 2JZ will support a lot of power before you need to beef it up. It will save you some money and trouble if you start with the turbo motor.

[mikes_classics_68]

ah great thats exaclty what i needed to know thanks alot so hmm now i just gotta find one also whats the best year from 93 to 98? is there like the cherry year? thanks again

[TcmaBoy]

Any year will do.

I have never seen anyone grenade a stock clutch pack LSD, only the TORSEN from shock loading. Not all N/A MKIII's have open differentials, the sport package came with a 4.3 LSD. Also the 1G's were not Euro only engines, they were sold almost everywhere except the US, we got shafted on EVERYTHING except digital climate controls and no speed cut.

[Yellow 13]

The sport package N/A would be the model that comes with TEMS right?

No, TEMS was available on all MKIIIs.

[Yellow 13]

So how would I be able to tell the difference between the sport N/A and normal N/A?

Edit: Sorry to get off topic.

[projectsupramk3]

Not a problem. I suppose the easiest way to tell would be to look for the yellow "LSD fluid only" tag on the differential fill plug. Could also look at the engine bay information tag.

The VIN will also give you the info you are looking for, but the axle code is easier to look up.

There is an axle code on your info tag in the engine bay. You will see a series of codes. I believe the sequence is color/trim/axle/transmission.

The axle code will be L### meaning letter, number, number, number.

The last number is what we are interested in.

2= 2 pinion non LSD

3=2 pinion LSD

4=4pinion LSD

5=4 pinion LSD

If I remember correctly the NA cars came with 2 pinion diffs while the turbo cars came with the stronger 4 pinion diffs. So, on a NA car with an LSD the last number should be a 3. NOTE: 2 pinion means that there are 2 spider gears in the diff. 4 pinion means that there are 4 spider gears in the diff.
