If you have a low mileage N/a 5speed is it best to do a Na-T or a Na-TT conversion

I have read so many of the threads on here and am still up in the air about what to do as sourcing a reliable yet cost effective turbo conversion is a pain in the arse it seams. I thought i would check out how crap suprastore can be by emailing them and seeing how long they take to get back to me just for a laugh which is three days atm.

I called AFR tuning in horsham the other day and spoke to the guys there which seam genuine and not just there for your cash and he recons a TT conversion would be around £2000 ish with sourcing the 2jzgte engine as well which sounds good to me and my probable outcome to save agro.

Anyones advice on where to go would be appreciated as i am not after monster power just around 3-400bhp and keeping what can be stock stock for a while so i can pay my loan off and then consider going crazy. I know i could just sell my Na and get a TT straight away but i fancy doing it the hard way just to challenge myself over time and more than anything i am sulking about not having a UkTT or a GZaerotop which if anyone fancys swapping you get my car and a complimentary go on my mum.

It's been covered more times than I care to remember to be honest. In every thread the general recommendation is the same, go TT. I would always recommend selling up and getting a proper TT to save you any agro but if you have a car you know inside out then it might be better to go for a transplant, as long as you don't plan on selling it on (it won't be worth as much as a genuine TT).

I cant see selling it coming up soon seeing as where i live no-one around here seams to have them so it makes a nice change to have something else from the million ford focus you see driving about. I like the idea of it sitting on my drive plotting to kill me one day in the rain.

Once again.

IMO its simply not worth coverting a Auto n/a. Unless it has had alot spent on its body work, or its an aero top. A 5 speed would be better however i would consider a 1jz swap as it will be cheaper and mate up to the w58 box just the same.

In short if you have a standard ish n/a auto sell it and buy a tt auto.

As said above, You could go through all the hassle of putting a TT in it. But when you come to sell it i think most people would spend there money back on a genuine one rather then a conversion.

Trouble is you said above you were going to eventually going to go crazy on it. wasted money i think!

There are quite a few members having an sz model with an 2jz-gte engine, One of the positive points is that if you let your conversion done by an AFR, for example. The tuner/mechanics working on the project will test the engine first before it gets installed, think about all the fresh liquids, filters, gaskets, overall general inspections. They will probaply also have look on the clutch etcetera, and if the old NA clutch is worn out they will fit an new one or even stronger one to cope with the gain in bhp. But in the end you will know what jobs are done, you know that the powertrain is freshly installed,tested and good. (and you can get it on black and white)

But then you have an NA-TT supra running stock boost, for running more boost on the setup you have, you will have to change the W58 which is only rated for 260rwkw (+/-350hp) for the Getrag 6 speed gearbox. Which is also an expensive operation. But as said earlier, the supra gets again an used part but probaply checked gearbox, you can choose to get your gearbox refurbed which is the best you can do. Then you know for sure all the inner parts are checked up by an specialist. If you will have these jobs done by an specialist, you will probaply spent more gbp then when you bought an tt-6 speed in the first place. But don't forget that in this example your supra gets converted by an specialist, you've got all parts checked up etc, invoices for administration etc.

I think that this is not comparable with an second hand supra. Off course there are exceptions, the price tag is there off course. But get your second hand supra in the same state, get your engine checked up by an specialist, get the gearbox refurbed, get all the liquids professionaly exchanged, get a new clutch etc installed. In the end all these extra steps needed to convert your NA into a professionally build tt-6 speed the correct way will cost you more then a 6 speed tt, but is it worth it, good question. Don't forget that an engine conversion, gearbox conversion including drivetrain changes are still the basics, the swaybars on a N/A supra are different from the tt ones, you will also come across the fact that the differential mounted on N/A supras differ from the tt versions, all this can be fixed, but will cost you money. Fair enough, all these things needs to be taken into consideration when starting such projects, I can give my opinion Graham, but in the end it will stay an sz model, dont forget that for insurance purposes the sz model came with an 2jz-ge, not the sequential twin turbocharged 2jz-gte. If you can pay for this all, and if you deffinately don't want to sell your N/A and if you want all the thrill you get from your N/A being a tt-6 converted supra, it's a long road,

swaybars on a N/A supra are different from the tt ones,

N/A and T.T. anti-roll bars are the same and so are the rear struts and springs, just slightly heavier springs on the front of the T.T. due to extra weight of turbos.

Ok, didn't knew that one, thanks for correcting me. (see i don't know everything)

Oh and welcome on board, off course.

Cheers for your answers guys its nice to have something to think about afr said they would convert my 5peed into a 6speed at the same time just seamed a possibility as my car cost only £2700 even sinking 2-3k into it didnt seam to bad as i have had the car looked over and its sound so sometimes its a question of better the devil you know over selling and getting a new car which for some of the twins i saw up for sale 5-6k for around 80k miles seamed a lot over having a pro built engine.

Maybe AFR and keron or anyone else that does conversions should start there own national Na lottery where once a week some lucky soul gets what they want which i for one will be a weekly ticket buyer.

On a personal note mark tozer replied to me about the Na turbo kits that claim they are full kits which was helpful for someone like me, All i asked was if there was any other bits that needed to be ordered as well and he kindly replied "read it over and over again from the top of the page to the bottom".............. Top bloke and thanks......I have now ordered 15kits as they seam to be a "GREAT" company and have emailed xs power who sell similar kits that they need to sort it out as telling me i needed extra inter cooler pipework that would have to be modded for na , upgraded fuelling and ecu change or re-map is just not helpful enough especially when they took all of 9 hours to reply.

At least on the plus side now when my 15 turbo kits are shipped in (2-3days) or is it years???? I can slap that on but in the meantime its a waiting game of replying to that email about someone needing my sort code and account number and booking my easy jet/ryanair/suprastore budget london to new york flight that will most likely land in ireland

you have abought 15 turbo kits??

Ahh the forgotten language of sarcasm. You'll do well here Graham

Guys..... he's kidding due to the crappy response he got from the sellers

N/A and T.T. anti-roll bars are the same and so are the rear struts and springs, just slightly heavier springs on the front of the T.T. due to extra weight of turbos.

I always thought the arb's were different between na and tt but that they were interchangeable?

Aww dam it i thought a newbie had get 15 NA/T kits

I don't consider myself that retarded....... well at the moment anyway. If i get to that stage in my life it will be obvious as i will be driving around with a sticker saying turbo on the back and the sadest thing of a a whistle kit in the exhaust just so i feel like i have a turbo....... maybe a turbonator as well just to complete the look.

Where do you guys think the best place to source an engine is which i know is most likely a noob question but when i looked myself i found a company called ideal engines in london i think and a 2jzgte engine was about £1200 but typically i found some people had problems with the quality of there stuff........ Are there many honest people left that sell online or is that just wishfull thinking on my part.............. http://www.marktozertillidie.com/mysmillingface
