NA-T vs TT


Guest TheRedViper

Recommended Posts

This subject is a minefield.

 

- TT turbos are a factory setup with factory spares and support, NA-T kits often have bespoke parts which are difficult to source.

- TT turbo system superior quality to most NA-T kits

- Factory TT uses stock ECU, NA-T need aftermarket ECU.

- NA-T can potentially perform better than TT if expensive parts are used

- NA-T can be more reliable than factory if expensive parts are used. Much simpler system is easier to diagnose faults than complicated sequential system on TT.

- Factory turbo gearboxes are good for tuning, factory NA ones aren't. NA auto gearbox can be easily upgraded for big power though.

- NA-T can potentially sound nicer, and look nicer.

- replacement NA engine circa £250. Replacement TT engine £2k

- NA engine is awful to service due to the Y-shape intake pipe going over the spark plugs. Given the plugs will want changing regularly when tuned, I would only consider NA-T with an aftermarket plenum.

 

You can build a nice pre facelift NA-T auto for circa £6k. You can buy a nice prefacelift TT auto for that too.

 

Basically, I would buy the tidiest, best built and maintained car of either type that you can find with your budget.

Great answer Jay! Finally someone who doesn't just blast NA-T!

You shouldn't need to go UK for insurance, when I did mine it was the same or within £30 to insure a Jap import. Just use a specialist, the normal insurers will do nasty things to your wallet.

 

Who are you insured with? If I go through admiral I can at insured on a UK spec TT for less than £750 when I'm 21, however it seems to be about 2 grand if it's a jap spec!

Na is crap.i drove my na for about 500km and decided I needed more power. That's why I've started on my na-t conversion. Mind you I used to ride a yamaha r1 as a daily so I'm used to big power.

 

I loved my Na, granted i wouldnt entertain the idea of a auto na, but manual .. it a fun car that is quick enough (especially for someone young with no rwd experience) that being said my TT is no animal wanting to put me in the bushes every time i boot it. My 50p. if you want a quick car that is nice to drive get a TT. if you want something that looks great is cheap to run and fairly fun to drive get a na 5 (just dont expect not to get embarrassed by clio's and and type R's)
