yea i just found that...the 2jz is a non-interference engine....super...are you sure the headgasket for the mkiv is bad? ive only heard of problems for it for the 7m not the 2jz...for the 2jz i heard the head is just as good as teh bottom end, as for looking for a supra...just look for the basics...like rust, leaks, boost leaks, definitely take a test drive...u usually dont find stuff just by looking at it...check the compression...not sure...but i think the compression on that motor should be about 140-147....i think ill have to double check on that, all the cars were the same that were sold here in america.., if i were you i would get the turbo...but then again some prefer the n/a route...i know some people with 11 sec n/a supras....so keep that in mind

Oh, I'm sure I will do a turbo swap on it one day, but that will probably be after I get out college, in about 3 years. As of right now classes take a lot out of me finantialy, that is why I'm dumping the Eclipse. As of right now I want a car that I know when I get into it every morning it will get me where I want to go with out the hassel. Here in Oregon it's not to fun to ride bike year round.

Are you sure it's not an interferance engine? It has detents in the pistons for valve clearance... The 2JZ is solid as a rock, it's typical toyota all around, EXTREMELY overbuilt and durable.

Timing belts have a bad rap for some reason, though they can be nearly as durable as chains, and are a lot lighter and have less drivetrain drag and noise. They're also a lot easier to replace. Very very few problems with the MkIV besides the high price tag :lol:

the motor is pretty solid...everyone upgrades hte timing belts though so usually htat isnt a problem

whitetiger777 · 08-12-2005, 07:23 PM

What do you mean by upgrading the timming belt? Do you just mean replacing it, or is there a particular brand that is better than Toyotas?

Humm, after looking at all the questions other people have I'm surprised you all haven't made a sticky, or what looks like you call a pinned, that states all this info. Thanks again for all the input.

well when upgrading the timing belt you can change the belt itself...rather than using a stock belt you can go aftermarket for a stronger more durable belt thats less likely to break, i havent really looked at timing belt companies...i know there are some out there maybe ill look later

Greddy is the only maker that I know of, and it's a couple hundred dollars. If you're going to get cam gears and start tuning with cam setting, might as well replace the belt while you're there...

Another question has come to mind. I was wondering how well the targa tops hold up to water. I live in Oregon which is rather wet for about half the year. Do the targas have issues with leeking? My old Miata did, and my friends 2nd Gen MR2 T-tops also leak rather bad...even after replacing the seals. Will the targa have this problem as well?

Poodles · 09-04-2005, 05:46 AM

Well...as with any car with a removeable top...they CAN leak..

whitetiger777 · 05-31-2006, 06:13 AM

Ok, so I'm back again...still with out a supra. It looks like turbo MKIVs are easyer to find for some reason. Can someone shoot me off a comparison or the NA and the Turbo...focasing on MPG. Stuff they have actualy witnessed them selves would be best. Also what are the weeks spots in the turbos system. Like in the Eclipse I had to replace the BOV fast because it leaks.
