imi Posted June 24, 2011 Share Posted June 24, 2011 neither, sell it and buy a TT or a single T - will work out a lot cheaper and less hassle. Quote Link to comment Share on other sites More sharing options...

welshbuddy Posted June 24, 2011 Share Posted June 24, 2011 alot of people say it works out cheaper, in some cases it doesn't , a tidy TT is like 8k? NA-T could cost 6k Quote Link to comment Share on other sites More sharing options...
Morpheus Posted June 24, 2011 Share Posted June 24, 2011 (edited) Edit, there were no replies when I wrote this.... Hi, How much time and money have you got? I'd go for twins for driveablility as you can have a smaller primary turbo that will spool faster and be nice for daily driving but a bigger secondary for ultimate power. All down to your driving style and budget but it seems like very few ever go twin. It's much more complex and for an NA, you'd have to rebuild the engine to take the power unless you keep it below about 8-9psi of boost which you can easily achieve and exceed with one small turbo. Not much point in going with twins unless you go big, in other words, then it's mega expensive and top end power is no better. At the highest levels, it's all down to money and tuning/mapping = reliability. I had an NA and considered boosting it but it's about £2k+ for a basic conversion if you do it all yourself. Might as well swap the engine to a GTE. Then, if it's not enough, you're starting with a more suitable engine with the right pistons and compression ratio and won't have to do as much work on it for some good power. I do prefer the way NA's drive though, up to a point, then they lack the power to pull through the mid-range in 3rd that a turbo has but for busy roads, you're better off with an NA and just keep it in 1st and 2nd! Have a search around the site for a few threads covering this topic, as a few are considering or doing this at the moment.

welshbuddy Posted June 24, 2011 Share Posted June 24, 2011 if you want around 500-600bhp , you will need to TT or Single, When i got NA-T i only want around 450mark. Quote Link to comment Share on other sites More sharing options...

Abz Posted June 24, 2011 Share Posted June 24, 2011 Question is though, what are your plans on the car? If it is to get dyno numbers I know a couple which could give you 500bhp for a NA-T. What will you be using the car for & how often, it is better to long term plan. Remember going from a TT to a single you would roughly want to budget £10k for that part of the jump. If that is your end goal then I'd look at getting a TT engine in there. Quote Link to comment Share on other sites More sharing options...
pezzler Posted June 24, 2011 Share Posted June 24, 2011 im lookin to spend arnd 8k in this 1 years time maybe go tt frst then single btwn 500 to 60bhp If you're going to be running the 5-speed box, then it will probably die a very brutal death with those projected power figures If you're eventually looking for about 600bhp (if you are in fact serious about all this), then you will need to have a getrag 6-speed conversion which will cost you a fair whack (used the search bar), or the other option is to go with a built autobox, also not a cheap option. Bearing all this in mind, the best option for you would be to sell your n/a, add that to the £8,000 you have budgeted for the conversion, and buy a tidy TT 6-speed from a member when one arises. When you add it all up, including your future plans: TT engine transplant, single turbo conversion, 6-speed conversion, TT diff, UK TT brakes etc....etc. It all becomes very expensive, the investment in a decent 6-speed TT now, will probably save you cash in the long haul Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted June 24, 2011 Share Posted June 24, 2011 You can get a good TT for 5 or 6k, you cant go NA/T or TT on the cheap or its just going to be unreliable Quote Link to comment Share on other sites More sharing options...
Morpheus Posted June 24, 2011 Share Posted June 24, 2011 All good advice but means a reluctant sale and re-purchase. Seriously, I thought about going NA-T and 11k later, I have a stock TT VVTi when I could never justify more than 4k at first for an NA and could have bought a big single for the same amount. Long term, it's cheaper to stump up the readies for a decent car unless you're happy with what you've got. Either way, good luck and learn all you can first. More haste, less speed, as my Mum used to say....... or was it more speed, less waste? Was too busy bouncing off the walls! Quote Link to comment Share on other sites More sharing options...

a98pmalcolm Posted June 24, 2011 Share Posted June 24, 2011 neither, sell it and buy a TT or a single T - will work out a lot cheaper and less hassle. plus 1 plus 3 as Josh agreed aswell. The TT engine (2JZ-GTE) is a much stronger engine than the NA. You will better a nicer gear box and little extras. Quote Link to comment Share on other sites More sharing options...
