I currently have a 97 Eclipse GSX and have found that I'm tired of modding. I curantly have an Aprilia RSVR, so if I realy want to go fast I still can. I would like to pick up a MKIV Supra NA, but have a few questions for you all.

First is what kind of inheirent problems are associated with this car? (i.e. the Eclipse is subject to crankwalk, and the timming belt jumping teeth) So, basicaly what you do all find are the common problems.

Second, is the 2JZ an interference engine?(will the pistons make contact with the valves if the timing belt breaks?)

And what do you all find is your average mile per gallon, and what occtain is required for the car? Can you run regular, or must you run pluss, or supreem?

im new here so i dont knowmuch but i do know that the headcasket (stock) might break. best bet is by a new one and tighten bolts to 7s lbs. (not sure) as of gas i think its plus only not sure either....

the 2jz motor is the most tunable engine in the world...its one of the most durable engines on stock internals...the other being the rb motor from nissan, there arent that many problems from the motor from teh factory...i think it was basically perfect....as for the avg mpg it changes...the more you mod the car..the less you getm which is the same for any car you mod, as for octane...usually premium is good enough but if i had one i would put supreme all the time....but then again as you mod the car more and more you will need a higher octane...just like any other car

Cool, getting so good info here. Does anyone know if the 2JZ is an interferance engine or not though. Also if some one could give me a ball park guess at the MPG on a completly stock NA.

Thanks

an N/A supra stock will get you about 18mpg in teh city and 24 mpg on the highway, not sure what you mean by an intereference engine though...

An interferance engine is an engine where if the timming belt breaks the pistons make contact with the valves, usualy destoying the valves and pistons. A non interferance engine, such as that in the miata, if the timming belt breaks no damage occurs to the engine. All you have to do is purchase another timming belt and re align the cams.

im not sure if it is an interference engine...imma try and find that out, i think it might be...but im not sure ive never checked the clearances

Also what type of stuff should I take the extra time to check out when viewing a supra I'm thinking about buying? Was there also a difforent set up for California cars due to emissions? Or were all cars sent the U.S. the same?

P.S.
SupraMan1784 I aprieate all the info you've given me.

All cars that were sent to the US are the same....Really, with all supras be wary of a seeping or blown Headgasket....You won't have as big of problem with this with an N/A because your not boosting, but but a Metal HG and New Head bolts and Torque them to 82 ft lbs....thats always the biggest one and you say you want N/A, well before you know it you will want to do a Turbo swap...The MKIV is one of the most reliable cars out there just maintain it correctly and she should go 250,000 mile no problem


btw....the I-6 is designed as a non-interference engine and make sure you get a compression test
