scott87 Posted October 23, 2012 Share Posted October 23, 2012 Im sure this will have been asked before or someone will have covered this, or perhaps tis such a stupid question no one has.... If say someone has a twin turbo and decides to go single and takes all the twin bits of there car. Can these then be put onto an n/a, i know the engines are different but can an na become a twin in this way or is it just completely pointless. I assume you could use the standard twin ecu and things like that. I imagine the cost would get out of control as apposed to just fitting a twin engine.

ripped_fear Posted October 23, 2012 Share Posted October 23, 2012 one word....No, its not possible to bolt the standard twins on a GE block, NA-t or NA-tt is the only option Quote Link to comment Share on other sites More sharing options...

Just trying to gauge costs. Quote Link to comment Share on other sites More sharing options...

Just trying to gauge costs. NA-TT is a TT engine swap and NA-T is a kit you can buy or piece together yourself. Look at Whifbitzs NA-T kit which shows you the parts and gives you a visual image to some degree about what is swapped/fitted. Quote Link to comment Share on other sites More sharing options...
alex2jz Posted October 23, 2012 Share Posted October 23, 2012 Converting the NA engine to a TT one is not possible i'm afraid. best option : fit TT lump. Downside : Availability. Second option : Single turbo conversion on the NA engine. : Downside : Cost, Reliability. Quote Link to comment Share on other sites More sharing options...
David P Posted October 23, 2012 Share Posted October 23, 2012 If you fit a T.T. head to your N/A engine it's doable. Quote Link to comment Share on other sites More sharing options...
scott87 Posted October 23, 2012 Author Share Posted October 23, 2012 Oh i thought you could tt a na engine using aftermarket. Ok i undersstand now. In that case going single is far cheaper than buying a tt lump as far as i can tell. Cheers guys i will start shopping :-) Quote Link to comment Share on other sites More sharing options...

scott87 Posted October 23, 2012 Author Share Posted October 23, 2012 If you fit a T.T. head to your N/A engine it's doable. Do tell? Stock turbos and ducting is easier to get than a stock tt lump. - - - Updated - - - Going TT is cheaper than NA-T... Really? Ive seen tt engines box and bits go for like £3000. Ive quoted parts for a turbo conversion to be less than this as i wont be paying labour. Quote Link to comment Share on other sites More sharing options...
safcdixon Posted October 23, 2012 Share Posted October 23, 2012 A tt engine and autobox can be had for 2k add .5k for bpu add another 1k for fitting, im sure a reliable na-t making bpu power cant be had for 3.5k, can it? Quote Link to comment Share on other sites More sharing options...
SPG Posted October 23, 2012 Share Posted October 23, 2012 Probably cheaper doing a GTE swap in, after you consider all the variables. Quote Link to comment Share on other sites More sharing options...

I would want to be manual, that is where i was getting the much higher price for a tt lump, unless you can run a tt on the standard 5 speed. I have been planning a smallish single build, and by planning i mean considering. I dont want mega power but turbo is just one option, im also considering a few alternatives.

You would have the same issues running a TT on a W58 that you would running an NA-t so you still need to take the box into consideration.

scott87 Posted October 23, 2012 Author Share Posted October 23, 2012 If not it's time it was. Hmmm that would be an ideal solution.... I ideally would like stock parts rather than going single as reliability has been a thought. Quote Link to comment Share on other sites More sharing options...

Just trying to gauge costs. The most cost effective way would be to sell your NA and buy a TT. Quote Link to comment Share on other sites More sharing options...
scott87 Posted October 23, 2012 Author Share Posted October 23, 2012 The most cost effective way would be to sell your NA and buy a TT. ? Really i havent seen them for less than 6k in similar nic to my na. Parts are definitely coming in cheaper than that! Quote Link to comment Share on other sites More sharing options...
David P Posted October 23, 2012 Share Posted October 23, 2012 Stock N/A bottom end is good for 600 bhp and will take 1.1 bar boost @ 10:1 compression, it would be quicker than a T.T. lump too because of the higher compression. Just pay attention to efficient cooling of the charge. Quote Link to comment Share on other sites More sharing options...

Just pay attention to efficient cooling of the charge. You have definitely got me thinking. Would i need to alter anything compression wise or would running the higher compression be ok? parts wise it would be a quite short list then. Ecu, turbos, manifold, tt head, and nice big cooler (im assuming air would be suitable as apposed to charge cooling)? Quote Link to comment Share on other sites More sharing options...

You obviously are not looking hard enough then We have had great example sell on this very forum for £5k, if your NA is as great as you say then you should get at least £3.5-4k for it which means it only costs you £1k for the TT. Which is a heck of a lot cheaper than converting an NA to a TT. Quote Link to comment Share on other sites More sharing options...
David P Posted October 23, 2012 Share Posted October 23, 2012 As long as you can do the spanner work yourself it would be the cheapest way to go. Most on here don't know which end to pick up a spanner and their advice reflects the added cost for this labour. I would leave the compression stock and use ARP head bolts.

safcdixon Posted October 23, 2012 Share Posted October 23, 2012 (edited) would a garage really charge 1k to fit an engine. Always done it myself but never thought it would be that much! Budget more than you think theres quite abit of work involved engine, tranny, bpu parts fitting and wiring ive never had it done but i woulda thought it would close too a grand Most on here don't know which end to pick up a spanner and their advice reflects the added cost for this labour. Was that aimed at me? Edited October 23, 2012 by safcdixon (see edit history) Quote Link to comment Share on other sites More sharing options...
