rg500 Posted July 23, 2018 Share Posted July 23, 2018 I wondered if anyone knows a way to turbo a N/A mkiv supra without spending over £5000 I looked at the whifbitz conversion and am quite tempted at the moment it’s a little out of reach and just wondered if anyone has put a kit together successfully by buying specific parts to make up a kit.

jamesmark Posted July 23, 2018 Share Posted July 23, 2018 It can/could be done on a budget. Will probably take you a long time to gather the parts. However it would probably in the end be cheaper and quicker buying a new kit, as 2nd hand parts are a gamble. If it is worth doing it is worth doing it right. As you could end up paying for it in the long run. Other thing to bear in mind, parts are not getting cheaper for these cars. Quote Link to comment Share on other sites More sharing options...

I'm running 11psi on a stock engine Quote Link to comment Share on other sites More sharing options...
griffsplace Posted July 24, 2018 Share Posted July 24, 2018 There is a youtube series, look up Bluudys Garage, where he does it pretty cheaply and with basic kit. Think the guy has joined on here now. Quote Link to comment Share on other sites More sharing options...

Scooter Posted July 24, 2018 Share Posted July 24, 2018 I would only take on the cheap NA-T way if I knew 'people' or could diy lots of it, otherwise I think it might be a false economy. Eg cheap manifold, the flange isn't square, or cracks after 'x' thousand miles, if you have can weld and grind whatever it's all part of the fun (for a few years at least!), or it's multiple trips and new parts (the ones you should have got the first time!) Whitbitz kit may seem pricey but won't have the above issues (you are basically paying up front for problems/expense you will avoid and that are 'likely' to incur going cheap at the start). Some would say if you are baulking a bit at the price then perhaps steer clear of modding one, I would simply say it's a balance or cost vs longevity, long term goals etc. If you don't change your oil on it even then you need to consider things carefully and it may be better biting the bullet and paying more up front and then at least you solidify a relationship, say with Whifbitz, to ensure a smoother ongoing ownership experience? Research, research research at this point including pm'ing the current NA-T owners ie straight from the horses mouth. Quote Link to comment Share on other sites More sharing options...

Darren M Posted July 24, 2018 Share Posted July 24, 2018 Could any na-t guys put up their build parts and from where they were sourced to help fellow members who are on the brink of doing this just to help people get a better idea of budget etc. Thanks Darren Quote Link to comment Share on other sites More sharing options...

rg500 Posted July 25, 2018 Author Share Posted July 25, 2018 You say you used the whifbitz turbo kit , why did you need to buy extra bits as I thought that the kit came with everything needed to do the conversion also how much did it cost.

I bought the first version of the kit years ago which only came with a side mounted intercooler option and I wanted a front mount. So just pieced that part together myself. I went second hand on injectors as they were a third of the price of new ones with the Whifbitz kit and had been freshly cleaned/tested. Same idea with the ECU, it was only the Greddy eManage piggy back that was offered at the time and I wanted to go standalone. Fuel pump upgrade was necessary for that little bit more boost I wanted to run. Stock one will run out of juice at low boost levels. Sandwich plate was for my gauges which I personally feel are absolutely necessary on an NA-T. That lead me to an oil cooler as I was passing 130degree oil temps on even fast motorway cruising. Whatever you think you can go NA-T for...double it. There's always unexpected things that come along. I was about 9k in the end I reckon. That included a clutch as well that I bought from Chris Wilson. Quote Link to comment Share on other sites More sharing options...

What sort of boost you think you'll crank it up to? I'm contemplating a headgasket and stud upgrade just to see what my car can do before doing it properly with a rebuild eventually. 20psi looks to be about the limit from what I can see with just a HG Quote Link to comment Share on other sites More sharing options...
Darren M Posted July 25, 2018 Share Posted July 25, 2018 All great information and very helpful to members including myself contemplating doing this. I just don’t want to sell a limb to afford it ! Quote Link to comment Share on other sites More sharing options...
sidewaysdan Posted July 25, 2018 Share Posted July 25, 2018 I would definitely go ahead and do it.. I sold my single 6speed a few years back for peanuts and when the itch came again the price of a 6speed was to much for a weekend car.. so I bought a Na-t and it’s been superb no regrets at all. I’ve done some other upgrades since I’ve had it and it’s all a learning curve.. Quote Link to comment Share on other sites More sharing options...
