Quick question

[Curtis]

Hi i'm new here and a have a quick question for you,

the other day i was reading that the mk3 supra's mainly govern at 250km/h

and the right hand drive cars all govern at 180km/hour because japan had a cap on them or something.

Is this ture, and if so does it apply to MK4 supra's?

Yes, MK4s are electronically limited to 155mph. However, this is easily bypassed in US-spec MK4s by pulling the trac fuse.

Okay cool, im looking at an Mk4 1993 with 78 000 km 2jz non turbo for $9000, worth it?

For what it's worth, imo, I'd never buy a non-turbo. It's nowhere near the car that the TT is - pretty much every component is downgraded except the chassis itself.

Yeah i see what you mean, i can always buy a single turbo for it. And its a 2jz, so great potential right?

It's an automatic btw, want the link?

The 2jz-gte and the 2jz-ge are similar engines, but they are not the same. The non-turbo ('ge') version has higher compression pistons (which is bad for forced induction), a completely different cylinder head, and no oil squirters to cool the pistons. Add that to the fact that the entire abs braking system, transmission, differential, ignition, ecu, suspension, etc., etc. on the non-turbo mkiv is all downgraded. Without a huge investment, it'll never be anywhere near what you'd get if you'd start with a tt in the first place.

What about the single turbo's? How bad are they?

Sorry about all the questions but i don't have 30, 000 for a tt.

My friend has an 88 mk3, with a 7m-ge non-turbo, can he put a turbo on it, possibly tt?

Single turbo upgrade kits are great, especially on an engine designed for forced induction (like the 2jz-gte).

Any engine can be 'upgraded' to handle forced induction, but it won't measure up to an engine that was specifically designed for it. For example, you can lower the compression a bit by using a thicker headgasket...but that changes the shape of the combustion chamber which negatively affects the engine's performance. In theory, you could take a 2jz-ge, change the pistons, mount oil squirters inside the block, and port the head to better handle the forced induction...but doing all of that properly (including reassembly) would probably cost about $4K or so. Add to that the cost of the single turbo kit, plus installation, the upgrades to the ignition, fuel system, brakes, suspension, transmission, and differential, and you're looking at a LOT more than the $ it would have taken to get a TT in the first place. You may not have the $ for a TT right now, but work hard for a few more months and you'll have the car you know you really want right from the start. Just mho.

I was hoping on spending around 12, 000. Should i stick to mk3, or go for an mk4 with a gte, then upgrade to a turbo?

Actually the gte already comes with twin turbos.

I'm going to pick "option 3" out of the two choices you provided: Just wait and save $ a bit longer, and then get the car you really want.

Again, just mho.
