Spindoctor

No Covers for storage. We have an exotics painter that has informed us of all the evils that can happen to paint under a cover (trapping various off gasses and such). So it has been properly buffed and waxed then we routinely go into our storage shop and knock the dust off with a dust wand.

Hello All! I am hoping you can help me out with some info and pictures. We have been storing a customers black 02 Esprit w 918 for over a year. When we pulled it out to get it ready for the customer to pick up we found dozens of little paint blisters on the front deck. We have had a couple of our local paint guys confirm that it is coming from below the paint and was probably a prep fault. Our customer however is sure we spilled something on the paint and would like for us to repaint the car. If you you have similar experience or info\picture to help us properly inform our customer of his options that would be much appreciated. Thanks in advance - Tim H The Spindoctor

I always like to finish my posts in case someone was following along- In the race against the clock it was decided to stick with original compressor wheels. (the 60mm wheels and parts may be found under for sale items shortly) I rebuilt the left bank turbo with the core turbine wheel had it balanced installed and joy of joys no more smoke. If anyone is interested I would post pictures of the damaged seal ring groove and maybe video of the car on the dyno. Thanks - Tim H The Spindoctor Dynoauthority

The Spindoctor moniker comes from my being an AWD Dyno tuner. I have had a Mustang AWD twin eddy 500 for 11 years with over 800 cars across the rollers. Now back to our regularly scheduled question- Any info on these 60mm turbos as they apply to the 918 motor would be appreciated as I plan on using them instead of the OEM units. Any reason not to is what I am most interested in. Also, I have added the twin air\water charge cooler kit previously.

Basic marketing '101' Get your message in front of as many eyes as possible. Not all those reading the engine posts go over to the turbo posts or vice versa. The readers of either may have valuable and appreciated input - but they have to see the question first. Others may learn something they did not know they wanted to know. That and the one post was already locked!

UPDATE- The core turbos showed up and much to my surprise they had the 60 mm compressor wheel instead of the 54 mm. All else being the same what kind of tuning issues may I incur if I upgrade to the 60mm units? And does that make these cores the gt28 ? Thanks in advance- Tim H (this post is in addition to the one just below)

I have located a pair of build able cores and should get them early next week. John Welch of WC engineering LLC was very helpful and informative in regards to our search. I will post a "smoke free" update when finished! Thanks to all those who replied. Tim H

Great cataloge. Has everything you need to know accept the 10 fin tubine wheel of the lotus TB2531. Interestingly the SAAB 9000 is a nearly perfect match aside from the 11 fin count and the 6.6mm tip height. Thanks for the reply- Tim H

This has been posted in a couple of spots- Sorry if it seems out of place here! I know there is a WTB spot under for sale and wanted but people don't always look there. I have a 918 motor here that has been giving me fits with a rebuilt turbo (left bank) and smoke. Went through all the oil level tests I could think of just Incase it was an over fill causing the smoke. All the tests where done just to satisfy my curiosity as the right bank never smoked, so I knew from the beginning that the level could not cause the problem or they would both smoke. I have determined a quick dip stick test to verify that the 'Olive' is in the correct 103mm spot. Since you cannot pull the tube up with the head installed on the engine a quick way to check is to: 1) make sure vehicle is flat and level 2) fill the engine up to the full mark 3)put a catch bucket under the turbo 4)get down to the turbo oil return and remove it- allow the oil to empty out of the pan nipple for about 15 min. 5)Now check the level on your dip stick it should be rite at the lower 'Fill' mark. If not loosen the union and adjust the tube until it is. 6)Reinstall return 7)Replace apx 1qt and now it should be at the 'Full' mark. In my estimation the engine would have to be at least 2qts over full to cause a resting level high enough to sap past the seal rings over night. Remember when the engine is running the level is considerably lower and not likely to back up into the turbo. Which brings me to what I really posted about- The smoking on this vehicle turned out to be a bad turbine shaft. The pinch or squeeze seal ring on the turbine side of the shaft is located in a ring groove just like a piston ring on a piston. The groove on this one is totally worn out and the ring has no surface to seal against and thus lets oil into the exhaust. What I need is a replacement shaft- new would be great- high quality used OK. Garretts part # is 4359.2-1 This is for the 918 motor with the TB 25\31 turbos. ANY help locating this part by LAST week would be appreciated. I would gladly purchase a buildable core if there is one available! Thanks in advance- Tim H Dynoauthority Redmond WA 425-869-8324 If wanted I could post pictures of a good vs the bad seal ring and groove.

This is a copy of a post I have placed elsewhere. I know there is a WTB spot under for sale and wanted but people don't always look there. AND THIS RELATES TO THE FORMER POSTED (BELOW) Dumbish question about oil level and smoke. I have a 918 motor here that has been giving me fits with a rebuilt turbo (left bank) and smoke.

We have a national reman company local to us - Alamo. They can easily take care of the ass. My distributor has the rebuild kit and bearing end plate (compressor side) as they are common to many models of turbo. The turbine wheel is the odd part out so far. I would gladly buy a good build able core from someone who is up sizing. Thanks for the reply- Tim H

Power Technologies is a Garrett parts suplier. They helped me locate the Garrett # by looking up the Lotus A918E0060F turbo part#. The 4359.2-1 is in the Garrett catalog, however, availability was unknown when they tried to find one. When I try to get to Garrett directly I get reffered to distributors. I will keep looking.
