bobbywarne1983 Posted May 18, 2011 Share Posted May 18, 2011 I running things over and over in my head about what i want to do next now i have had the respray done... i have an N/A and i really want more power as we all no tuning an N/A just isnt the way to go..... so my options 1. ive seen the whifbitz n/a turbo conversion which looks really good. 2. find a second supra with a manual tt and do an engine swap... 3. sell my supra and with the money i have buy a 6 speed tt. I am swayed towards the n/a turbo route as the idea of having that would be epic. but then if im willing to spend 5k or so on the conversion why not just sell up and spend 10k on a 6 speed tt. what are your thought on my options guys would you rather make the car your own, or go the easier way and buy one with the power already (6 speed tt)... bare in mind i only use the car on the weekends as i commute by train to work so being without a car for a few weeks wont hurt me. all advice is greatly appreciated... cheers Quote Link to comment Share on other sites More sharing options...
d-_-b Posted May 18, 2011 Share Posted May 18, 2011 Im going to guess the majority vote on this will be "Sell the N/A buy a TT" ^^, However if you have put a lot of time into getting the outside / inside of your car looking how you want it OR you like your car how it is & just want more power then the 1st 2 options come into play. Selling the car and buying a TT does mean 1st you have to get the money you want for your car, which with things as they seem to be at the moment can prove a little more of a longer process than it used to be.

bobbywarne1983 Posted May 18, 2011 Author Share Posted May 18, 2011 Cheers Chris, i guess i have a few months to make up my mind as thats when my insurance is due for renewal... i have spent alot of time n effort on the outside ( losing and gaining a spoiler as you very well know and a full respray and de graphicing it) and it is in prestine condition and i love my bride seat and the carbon dash. As for selling my car it would be a bit of a difficult one as i would be looking for £5k for my n/a ( and i know you can get tt autos for cheaper then that) but with its miles and condition i feel its a fair price, but with the current climate of fuel prices and it being a 3ltr anyways this might put off first time buyers off....

d-_-b Posted May 18, 2011 Share Posted May 18, 2011 Full respray & removing the graphics - wow the car has changed a fair bit since I last saw it! Pics? : D Personally I would stick with it, but then I wouldn't like to think about ever selling my car. Didn't realise your's had a carbon dash! On the upside with insurance going up more people may be looking for cheaper to insure N/A's for getting into Supra ownership - however that is a bit of a guess : ) Quote Link to comment Share on other sites More sharing options...
bobbywarne1983 Posted May 18, 2011 Author Share Posted May 18, 2011 its actually cheaper to get insured on a uk spec tt then an imported 3.0n/a for some reason, well pretty much the same which is honestly weird seeing as there is around 100bhp difference... yeah i have been a busy boy with my car Quote Link to comment Share on other sites More sharing options...
3LL Posted May 18, 2011 Share Posted May 18, 2011 Its pointless selling up now you have had the work done.. I would go for a TT transplant, and BPU.. your looking at similar power levels for a lot less cash than na/t .. plus you can always go single at a later date on the TT lump.

Noz Posted May 18, 2011 Share Posted May 18, 2011 In my opinion its going to depend on what transmission you have. Unless you swap that as well, as auto NA won't like BPU power - 400bhp ish. im manual and im going through the stages of NA-T shopping list and to be fair, it probably would have cost the same amount of money to swap to a TT engine. if you want 320bhp go NA-T, if you want 400 you'd probably be best to swap and it will end up costing the same amount of money. You need to give yourself a power goal, this will depend on what transmission you have though. some people have had higher power on stock NA transmission but this is what i found recommending power levels: http://mkiv.supras.org.nz/techo.htm Go to the section automatic tt gearbox spec W58 5 speed manual in the n/a is good for 260 rwkw, Auto in the n/a 200 rwkw Gertrag 6 speed 600 rwkw Auto in a tt 350 rwkw 1hp = 0.735kw so..... 1kw = 1.341hp (ish) so we convert and we get: w58 348hp na auto 270hp gettrag 804hp auto tt 470hp Ive seen LOADS of cars push these figures and have NO issues but its just an idea of how far your pushing your box. These aren't figures set in stone just some info I found on another forum. Thought it may give you idea. Quote Link to comment Share on other sites More sharing options...

Well the 5 speed manual box is the W58, so based on the info Noz put up, it should be able to handle it, but no more (working entirely based on those figures) Quote Link to comment Share on other sites More sharing options...
bobbywarne1983 Posted May 18, 2011 Author Share Posted May 18, 2011 see if i had a calculator to hand i cud of worked that out lol... 260 x 1.341= 348.66 so it will be pushing the boundaries but will hold, not that im a hardcore driver, just a few blast here n there, then once its blown get a new one and take it on a few track days maybe and ruin the paint lol.. so my options, find a manual tt engine and all the trimmings, or go for the whifbitz n/a turbo upgrade...

Guest West. Posted May 18, 2011 Share Posted May 18, 2011 Sell NA and buy nice TT6 around 7-8k! For my personally.. NA-turbo it complete waste of money and i don't think it reliable too.. Quote Link to comment Share on other sites More sharing options...
Ricardod Posted May 18, 2011 Share Posted May 18, 2011 i went the NA-T route (custom gathered kit), it required a LOT of fabrication but at the end of the day i do have what i want to have on my car. i also have in mind that my W58 tranny could blow up due to running around 350 to 400 Rwhp... so i treat my tranny with respect which means no burnouts and other things that stress the gearbox . im saving up for either an R154 5spd off an mk3 or a V16X, depending on funds. as an R154 requires allot of fabrication i think ill head towards the v16X side...

Nic Posted May 18, 2011 Share Posted May 18, 2011 1. ive seen the whifbitz n/a turbo conversion which looks really good. 2. find a second supra with a manual tt and do an engine swap... 3. sell my supra and with the money i have buy a 6 speed tt. I am swayed towards the n/a turbo route as the idea of having that would be epic. but then if im willing to spend 5k or so on the conversion why not just sell up and spend 10k on a 6 speed tt. It will cost you a LOT more than £5K to do a reliable NA-T conversion, the Whifbiz kit alone costs almost £4K, add fueling upgrades, electronics, ECU/mapping, drivetrain, cooling, labour, etc. and you are looking at at least double that amount. The sensible - and probably the most cost effective - option is to sell and buy a TT. Fitting a 2JZ-GTE engine is an option but will probably cost you more in the long run when you factor in the drivetrain upgrades needed to handle the power and the lower resale value of the car compared to a genuine TT.

bobbywarne1983 Posted May 18, 2011 Author Share Posted May 18, 2011 excellent threads there mate thank you very much Quote Link to comment Share on other sites More sharing options...
bobbywarne1983 Posted May 19, 2011 Author Share Posted May 19, 2011 Well ive just done some calculating and with the figure i want 320-340bhp for an n/a turbo conversion im looking at £6500 and thats with doing everything through Paul at whifbitz. so thats £6500 for an extra 120bhp thats £54.17 per bhp.. not to sure if its worth it as of yet...
