Sean1933 Posted November 28, 2006 Share Posted November 28, 2006 Right people, I *may* in the not so distant future (if i get a new job i have gone for) be looking at undertaking a big supra project...engine, body, interior...the whole works. I have my ideas about bodywork, and interior will come later....but its the engine (turbo mainly) that im undicided... I have been reading so many posts about about different turbos recently but have got my head in a muddle and not really found the answers to my questions. I am undicided between a 67mm turbo and a 71/72?mm turbo (DBB probably). I will be wanting approx 700bhp but dont want to be pushing the limits of the T67. I also want to have quite good response as this is going to be a street car (track once in a while), not a daily driver but has to be reasonable. I would like people that have had these turbos on there cars to tell me what sort of power they were running, and what the response was like. I have a feeling that a 71mm DBB is going to be the best, but i want to hear from people that have experianced it personally. Can you also tell me which kits are good, as im confused on this front too...BL/PHR/Blitz/Apexi/HKS??????? Thanks all! Quote Link to comment Share on other sites More sharing options...
Matt Harwood Posted November 28, 2006 Share Posted November 28, 2006 Sean, don't take this as an insult, but have you ever driven a 700bhp car on the road? I've got a T67, and I'd prefer to quote a realistic ~500 bhp. In this cold weather, even when it's dry, my car struggles for traction in virtually every gear. I had the back jump at around 120 a couple of weeks back. - If you want a demo, come down to Maidstone and you're more than welcome. IMHO, the T67 in a manual is a great choice for a road car. It will come on full boost at ~4000 rpm. The same point the sequentials do. Giving a not too laggy, very usable, powerband. (DBB even more so). If you wanted to, you 'could' wind the boost right up and reach the 700, but you may find you can rarely use it. Quote Link to comment Share on other sites More sharing options...
wkdtime Posted November 28, 2006 Share Posted November 28, 2006 If your keeping the stock engine then i'd go for the T67 with a .67 A/R, it should see you around 550-600 ATF at 1.4 Bar. If you really want the 700 horses then i would really consider an uprated bottom end. Quote Link to comment Share on other sites More sharing options...
Sean1933 Posted November 28, 2006 Author Share Posted November 28, 2006 To be honest matt, no. I have driven a 500 rwhp skyline and it was awesome...but i am abit of a power freak and will always want to go faster. Its not so much a case of wanting 700bhp now, but more a case of wanting to be able to easily progress to this easily without having to change the turbo, ie wind the boost up... I think i will have to take you up on that offer of a ride though as i want to experience it first hand. PM details of when your free! Im in Eastbourne so not far away Quote Link to comment Share on other sites More sharing options...
Ian C Posted November 28, 2006 Share Posted November 28, 2006 Matt speaks sense. Also, once all the gear is in place the path of putting in a bigger turbo if you feel the need to is a lot easier than the initial single conversion step. Still not bored of a T67 here, although the DBB variant kicks ass over the journal bearing. I run 1.2bar most of the time and it's still a bit fierce on the traction front. -Ian Quote Link to comment Share on other sites More sharing options...
Sean1933 Posted November 28, 2006 Author Share Posted November 28, 2006 I have to say i have always been looking mainly at the T67, so i will probably take your advise and go that way. The only thing i really need to consider now is which make to go with? Any views? Cost is an issue as im not rich, but i want quality aswell. Also how much more does having DBB cost?

Paul Whiffin Posted November 28, 2006 Share Posted November 28, 2006 What Matt is saying is very true, if you want useable power on the street go for something around T67, keeps it nice and responsive, some of it depends if you use your car a lot or not and how good a driver you are, big power Skyline's(in a straight line) are a lot easier to drive that big power Supra's remember.

Im in Eastbourne so not far away 700 is practically drag power and will be a bitch to get down, Matt is right but its totally your choice!! I would be even more modest and probably go for an even smaller turbo, maybe a 61 or GT35r when I get round to doing it Speak to JamieP, Gamer or Kev Huntly there all pushing around your quoted figure I think Quote Link to comment Share on other sites More sharing options...

Im in Eastbourne so not far away I am running a T71GTQ and I am currently staying down at our flat in Eastbourne (Sovereign harbor south). You are welcome to pop around and I can take you for a quick ride providing the weather cooperates and the roads are dry. Not sure if it will make any difference to you though as I am running a BL uprated gearbox/3800 hi stall and I am assuming you have a 6 speed. Either way you can get an idea of the power delivery.

Sean1933 Posted November 29, 2006 Author Share Posted November 29, 2006 Gamer im going to have to take you up on that offer ...PM SENT I will almost certainly be going for the T67 Variant now thanks to all your advice, especially Matt. The question now is which variant...it seems to be between BL and PHR.... Quote Link to comment Share on other sites More sharing options...

Chris Wilson Posted November 29, 2006 Share Posted November 29, 2006 IMO choose a turbo a bit on the small side, and if it's an auto, go a size smaller still. Big power without response, on the street, is a disaster, and with an auto box, a total diasaster. Any major turbo upgrade without proper mapping capabilities (ie, standalone) is a waste of money, IMHO. Others will definitely disagree! Terry has good ideas for turbo sizing, IMO. I personally would ALWAYS buy a genuine Garrett turbo, for ease of repair, housing change, and the knowledge the exhaust housing is made of correct spec cast iron that won't warp the flanges or crack. I would always go cast iron manifold on a road car, unless you have a BIG BIG budget for a tubular Inconel manifold with proper support, especially if you intend eithe high mileage or track days. When a cheapo tubular stainless manifold cracks a welded repair is all but impossible as the crack is immediately contaminated by carbon.

Ian C Posted November 29, 2006 Share Posted November 29, 2006 The Boostlogic series are Garrett cores, and very nice they are too. Still haven't heard of a BL tubular manifold cracking I don't think they are that el cheapo. Other manifolds may vary in quality... -Ian Quote Link to comment Share on other sites More sharing options...
Muffleman Posted November 29, 2006 Share Posted November 29, 2006 Whereabouts in East Sussex are you ? If not too far from me I will take you for a spin. Mine is a Blitz K5-660R, and not a common choice. But it has a small a/r and a fair size compressor housing. Not the most powerful, but spools up very quickly and pulls strongly - it's a good street turbo and will keep you alert Hoping for a final dyno power run soon Quote Link to comment Share on other sites More sharing options...
Guru Posted November 29, 2006 Share Posted November 29, 2006 All sounds like good advice Sean. If I were to upgrade I would be in between the BL and PHR too for serious street power Quote Link to comment Share on other sites More sharing options...
Robbie Posted November 29, 2006 Share Posted November 29, 2006 On a manual I wouldn't settle for anything less than a 67, period! Quote Link to comment Share on other sites More sharing options...
