Geo Posted September 23, 2014 Share Posted September 23, 2014 So as i've been out the loop with a Supra for a while, and with my Engine build going on, once thats complete i'll be looking at a Turbo set up. So whats the latest Tech at the moment? With my Previous car it had a non-billet T67 .68ar and i really enjoyed everything about that tubby. It made 712bhp 600lbs/ft. With what i kinda have planned is a savage street car. I have no use for 800+ power, more so up here on Roads that are terrible and mostly wet all the time. With that being said, gimi the low down on the Latest tech Quote Link to comment Share on other sites More sharing options...
Chris Bailey Posted September 23, 2014 Share Posted September 23, 2014 (edited) Precision turbos get a high rating, they are bringing out a new version in the near future. PT CEA Gen 2 6870, They are aiming for it to spool like a 67mm with the power output of a 71mm turbo. Should be interesting Edited September 23, 2014 by Chris Bailey (see edit history) Quote Link to comment Share on other sites More sharing options...
JamieP Posted September 23, 2014 Share Posted September 23, 2014 62mm turbo will do 700bhp easy enough these days, but I wouldn't get to sucked into the latest turbo hype. Old school non billet 67 such as the T04z is still a decent enough turbo, do-luck car still goes like a rocket and spools plenty fast enough.

j_jza80 Posted September 23, 2014 Share Posted September 23, 2014 I would have a look at the Garrett GTX3582R, looks like a perfect street turbo. Should make circa 650hp depending on the rest, and have savage spool Quote Link to comment Share on other sites More sharing options...
tooquicktostop Posted September 23, 2014 Share Posted September 23, 2014 Agree the To4Z is excellent, I was happy with the S366 Billet from Whifbitz as well, made an easy 650 bhp with sensible boost Quote Link to comment Share on other sites More sharing options...

Geo Posted September 23, 2014 Author Share Posted September 23, 2014 awesome guys, i'll get a look at those and do some digging see what i fancy? Quote Link to comment Share on other sites More sharing options...
Chris Bailey Posted September 23, 2014 Share Posted September 23, 2014 Agreed the TO4Z is savage when it comes online, but they are hard to get hold of these days. Quote Link to comment Share on other sites More sharing options...
j_jza80 Posted September 23, 2014 Share Posted September 23, 2014 (edited) T04Z is still available from HKS. Plus, I think all of the HKS turbos are based on Garrett units? Certainly most of them are. Precision used to do the same before Garrett stopped supplying them.

Chris Bailey Posted September 23, 2014 Share Posted September 23, 2014 T04Z is still available from HKS. Christ, I honestly thought they were discontinued. Bet they're not cheap! Quote Link to comment Share on other sites More sharing options...
j_jza80 Posted September 23, 2014 Share Posted September 23, 2014 No, they're not cheap. In fact, they seem far more expensive than equivalent BW, Garrett or Precision units. Quality turbo though. Quote Link to comment Share on other sites More sharing options...
dangerous brain Posted September 23, 2014 Share Posted September 23, 2014 So you read about trims and all that jazz. Is it the trim that makes the difference between a Z and an R on HKS turbo's or just the fandangled intake on the Z? How do these GT3582's work in relation to the old school T67 72 88 etc? Odd question but what sort of size turbo's do diesels run and are they stronger or weaker than petrol equivalents? I know a few diesels run variable vane turbo's now, are variable vane turbo's available on the aftermarket for petrol cars or is there no point because of longer rev ranges?

j_jza80 Posted September 23, 2014 Share Posted September 23, 2014 GTX3582R should produce roughly similar power to a Greddy T88-33D, but with much faster spool. T78 is a smaller Turbo, and a much older design. Quote Link to comment Share on other sites More sharing options...
Scott Posted September 23, 2014 Share Posted September 23, 2014 I've always loved the GTX35r, looks like an amazing turbo. Quicker spool than the old GT35r (which was silly quick) and flows more at the same time. Amazing street turbo. Quote Link to comment Share on other sites More sharing options...

jazz1 Posted September 23, 2014 Share Posted September 23, 2014 You can not go wrong with Garrett turbos they are bullet proof, HKS range do superb quality kits and Lee is a HKS dealer with superb prices. Quote Link to comment Share on other sites More sharing options...
Nic Posted September 23, 2014 Share Posted September 23, 2014 Odd question but what sort of size turbo's do diesels run and are they stronger or weaker than petrol equivalents? Diesel turbos are designed to work at lower temperatures, they won't last long at the hotter exhaust temps produced by a petrol engine.

The good old HKS tubular manifold still performs with the best of them Though I would also be sorely tempted by one of Whifbitzs masterpieces Quote Link to comment Share on other sites More sharing options...
JamieP Posted September 23, 2014 Share Posted September 23, 2014 I wasn't recomending the T04z, I was just trying to point out that on the road you won't notice a great deal of difference between an old school turbo and the latest ones out there, picking the correct turbo for the setup/engine with the correct size .ar and wheels is more important than getting the lightest billet wheel available. ive always been a big Precision fan myself, my GEN2 6266, spools very fast (full boost at 3200rpm) and will do 700bhp with ease when I fit some cams. I was impressed with the borg Warner FMW 61 I had on the duck though, cheap turbo and overlaying the goose and duck graphs there was nothing between them.

dangerous brain Posted September 23, 2014 Share Posted September 23, 2014 Diesel turbos are designed to work at lower temperatures, they won't last long at the hotter exhaust temps produced by a petrol engine. So in all reality if my onset of the nee naaah noise on my 530D turns out to be a turbo on its way out then looking at a petrol T61 or smaller sized turbo on a custom manifold with waste gate might not be that bad an idea as long as I can push enough diesel in to cope with the additional available air?

Luxluc Posted September 24, 2014 Share Posted September 24, 2014 I would look out for a Gen2 CEA turbo from Precision. Like Jamie's current turbo, 700bhp potential and almost no lag. If you're not chasing big numbers, I would go for a Gen2 CEA 6266 (rated 800bhp) or maybe a Gen2 CEA 6466. Everything above will give you a lot more power. My CEA 6766 pushed 840 at the hubs ... impossible to use in the wet as I have to run semi-slick tires in the dry to have traction in 3rd gear.

bignum Posted September 24, 2014 Share Posted September 24, 2014 I went with a borg warner as they can be repaired/rebuilt cheaply, if a precision fails you may as well bin it. Quote Link to comment Share on other sites More sharing options...
mellonman Posted September 24, 2014 Share Posted September 24, 2014 I went with a borg warner as they can be repaired/rebuilt cheaply, if a precision fails you may as well bin it. have any rebuilds known to last as well ? Quote Link to comment Share on other sites More sharing options...
j_jza80 Posted September 24, 2014 Share Posted September 24, 2014 I went with a borg warner as they can be repaired/rebuilt cheaply, if a precision fails you may as well bin it. The failure rate on BWs seems quite high though, I know of several just off this forum. Personally, even if it means sacrificing a little performance, I would rather go with either Mitsubishi/IHI or Garrett. Quote Link to comment Share on other sites More sharing options...
