Mike B Posted May 22, 2007 Share Posted May 22, 2007 Summer time, a recent trackday at Marham, and the exploits of Jamie P got me scheming.. http://www.turbobygarrett.com/turbobygarrett/catelog/Turbochargers/GT40/GT4088R.htm It's on the way; GT4088R ar95... the car originally had a 40 on but I opted for the smaller GT35R. They don't make the smaller .85 housing anymore so I had to get the slightly bigger version It's the one thing I love about these cars.. there is so much you can change depending on what you want it to do. a summertime tubby and a wintertime tubby. Now I just need some R888's. happy days! Link to comment Share on other sites More sharing options...

Jake Posted May 22, 2007 Share Posted May 22, 2007 Nice one Mike. Where did you order it from? Do you mind saying how much it was? I heard today that my GT4088 is finally on it's way and will be here Fri. Link to comment Share on other sites More sharing options...
mikeyb10supra Posted May 22, 2007 Share Posted May 22, 2007 Everyone seems to be raving about this turbo....without sounding to patronising, whats so special about it?? has anyone plotted a efficiency map for this particular turbo yet as I would be interested to see it as it seems to be taking the board by storm? I was going to opt for its smaller brother when I get round to doing the whole single bit Link to comment Share on other sites More sharing options...

I was going to opt for its smaller brother when I get round to doing the whole sinle bit You're referring to the GT4088? Mike's is the GT4088R which is a different beast. It's the plain gt4088 that a lot of people are using. It seems to be a good size for the Supra and a decent power upgrade from the t61 turbos. It's also well priced, you get the GT tech for less than the price of a PHR t61 or t66/67 old style turbo. Link to comment Share on other sites More sharing options...

Mike B Posted May 22, 2007 Author Share Posted May 22, 2007 I listened to jamie p's specs, michel is going this way, terry S had one on this car.. and I am well impressed by the 35R.. it gets positive boost at 800rpm in 6th, and .5 of a bar of good solid pull by 1.5, and I have a leaking gasket! Tubby coming from Kyle, a shade under 1k, almost 2x as much as the journal bearing but I have been so impressed with the 35R I didn't want to trade down. I know it's stupid but sat on the motorway in 6th I hate being up and down the box to get power, the 35r dbb pulls so well at low revs that I never have to change down - even at 60 mph - such a lazy drive on long journeys - reading Jamie's posts his journal bearing turbo is not far off. I'm hoping the lag won't be so different. It's way more effective than jspec ceramic sequential in 6th. I have been in some singles that have nothing below 3. either way I'm sure someone would buy it off me if I don't like I'm on 650 injectors so I'm not going power crazy, so I have to be careful as I could potentially lean out...although the car has hks knock sensors and fbw throttle shutdown for knock, as well as an adaptive ecu.. no need for mapping Link to comment Share on other sites More sharing options...
Kranz Posted May 22, 2007 Share Posted May 22, 2007 has anyone plotted a efficiency map for this particular turbo yet as I would be interested to see it as it seems to be taking the board by storm? GT4088R will make 600hp @ 7000 rpm with peak torque at 5000 rpm. That's right on the limits of the map at 3.1 pressure ratio flowing 66 lb/min at peak power and 47lb/min at peak torque. That's 25.7 psi boost Link to comment Share on other sites More sharing options...
Mike B Posted May 22, 2007 Author Share Posted May 22, 2007 Good lad, what sort of power will you be looking for with that little puppy then? I really don't know - Terry says it's an extra 70, but his may have been the ar .85. Looking forward to finding out. I don't think it's necessary in the winter, but with the hotter days, grippier roads I think I can find a use for it! Comes with a free shovel to dig myself out of the grass at donnington!

That's right on the limits of the map at 3.1 pressure ratio flowing 66 lb/min at peak power and 47lb/min at peak torque. The map in the F-Con map is self adapting, although Reg tells me the car is due an update, as he runs the same system and has done a lot of work on it over the past 2 years. It does shut it's self down when it detects knock, I was getting a bit of this at Marham when it got hot using pump fuel, reassuring if not a little annoying sometimes.

jevansio Posted May 22, 2007 Share Posted May 22, 2007 Great choice Mike, when are you expecting it to be on & setup??? Link to comment Share on other sites More sharing options...
JamieP Posted May 22, 2007 Share Posted May 22, 2007 Sounds good Mke, im sure you will love it:) Not any more. He's on a PHR3 now. Not for long, new GT4088 should be here this week but as i have all the water lines in now im thinking i may aswell go for the "R" now aswell.

You may as well, it's hardly going to make it produce less power or spool slower. It's only money Link to comment Share on other sites More sharing options...

Mike B Posted May 22, 2007 Author Share Posted May 22, 2007 Great choice Mike, when are you expecting it to be on & setup??? It may be a few weeks - am flat out at work. I have a water/meth kit to put on, as well as a EGT sensor. I want to have enough time so I'm not working to a timescale.. get the job done properly! I don't even know where to get 888's from... I'll be asking Wez i think... my local tyre dealer was scratching his head. Link to comment Share on other sites More sharing options...
Mike B Posted May 22, 2007 Author Share Posted May 22, 2007 now im thinking i may aswell go for the "R" now aswell. It would be an interesting test for you - as you still have the map from the journal bearing turbo. I would be interested to see what the 6th gear low rev pull was like in comparison. The only thing is that if you melted your last tubby, it's a lot more money to spend on something that you could melt again. Having said that the garret website say the dbb's are a lot more durable. Still, 1k to put that theory to the test! Link to comment Share on other sites More sharing options...

jevansio Posted May 22, 2007 Share Posted May 22, 2007 When I bought them they were for my MR2 so were in 17's, price was very competitive & they were local which was a bonus. Link to comment Share on other sites More sharing options...
