Quick question

[Curtis]

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.

Alright thanks for all the help man, i might look around for an 89 single turbo 7m-gte.

That car i was looking at is right hand drive, my mom said i can't get a rhd, im only 17 so im still living at home and going to school.
