na supra to twin

Im sure this will have been asked before or someone will have covered this, or perhaps tis such a stupid question no one has.... :blink:

 

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.

one word....No, its not possible to bolt the standard twins on a GE block, NA-t or NA-tt is the only option

 

I know they wouldnt just bolt on as such, i was just wondering whether it would be cost effective to fit them to an na, or make an na-tt or just buy a tt lump. 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.

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.

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.

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?

 

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.

would a garage really charge 1k to fit an engine. Always done it myself but never thought it would be that much!

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.

The most cost effective way would be to sell your NA and buy a TT. :)

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.

 

You have definitely got me thinking. :eyebrows:

 

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)?

? Really i havent seen them for less than 6k in similar nic to my na. Parts are definitely coming in cheaper than that!

 

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.

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?
