mobythevan Posted April 18, 2005 Share Posted April 18, 2005 I finished my hybrid turbo upgrade on Saturday. I got a good scare when I started it up. Let it run for about 5 minutes at idle like directions said. Then revved it up a bit and the fan belt squealed(think I dripped some coolant on it). I thought the compressor ground out, I hate it when you get in that mode where you expect stuff to happen. I took it for a drive with the MBC still set like it was with stock T3. It was set to 14 psi before and everything worked great, ran 14psi with new turbo. Spool seems to be in the same neighborhood as before, if it changed any couldn't be 200rpm. The new turbo has 10 degree clipped T3 turbine. The new turbo pulls harder all the way to 6000rpm. Ran against my rev limiter for the first time. The car is faster by quite a bit(gtech shows around 40hp gain at same boost, does that seem reasonable with no other upgrades?). It will break the tires loose on pavement when the turbo hits in second gear now, didn't do that before. I am happy with the upgrade. Since I am at such a high altitude I am going to raise it up to 17psi which should be more like 14psi at sea level. BTW, I didn't have to retune anything in megasquirt after the upgrade. No ping and AFRs look good. I took it on a good 60 mile drive into town and everything seems solid. Quote Link to comment Share on other sites More sharing options...
Guest bastaad525 Posted April 18, 2005 Share Posted April 18, 2005 Very nice... to say I'm envious is an understatement Quote Link to comment Share on other sites More sharing options...
zxgtr Posted April 18, 2005 Share Posted April 18, 2005 What turbo did you get? Quote Link to comment Share on other sites More sharing options...
mobythevan Posted April 18, 2005 Author Share Posted April 18, 2005 TO4E 57 trim, I verified by removing the compressor housing and measuring the compressor wheel. T3 turbine with 10 degree clipped wheel. It is 60AR compressor housing and turbine AR is same as stock turbo was. Quote Link to comment Share on other sites More sharing options...
cygnusx1 Posted April 18, 2005 Share Posted April 18, 2005 Congrats on the upgrade. Isn't it sweet to be able to break the tires loose without having to drop the clutch. What numbers did the gtech give you? I still have to gtech my Z. I dont have many level roads with low traffic patterns. Quote Link to comment Share on other sites More sharing options...
yo2001 Posted April 18, 2005 Share Posted April 18, 2005 You should run a back pressure test and see what kind of pressure is in the exhaust manifold. Quote Link to comment Share on other sites More sharing options...
mobythevan Posted April 18, 2005 Author Share Posted April 18, 2005 The gtech showed 250hp which is probably about right for 14psi at my altitude. I would expect someone at sea level at 11psi to be right about the same. I am going to up to 17psi and see what it shows. Quote Link to comment Share on other sites More sharing options...
NISMO619 Posted March 31, 2007 Share Posted March 31, 2007 mobythevan after u installed your hybrid turbo charger did u have to re adjust your air flow meter ? i need to know becuase i installed a to4e hybrid turbo charger and my car starts but revs normaly at 900 rpm then drops to 200 then back up to 500 rpm then dies the only way to keep it alive is to keep my foot on the petal.

dosquattro Posted March 31, 2007 Share Posted March 31, 2007 Sounds like a vacuum leak or a leaky intake manifold gasket. Quote Link to comment Share on other sites More sharing options...
b__sosick Posted March 31, 2007 Share Posted March 31, 2007 a project that's going GOOD!?!?!? NO PROBLEMS?!!?!? Quote Link to comment Share on other sites More sharing options...
Brad-ManQ45 Posted April 1, 2007 Share Posted April 1, 2007 Check to make sure that the boot from your AFM to turbo is not split. (assuming you are using stock ZXT setup) When I had my T3/T4 installed (living in a condo - no place to work), the Z shop that did the work had to trim the boot. When they did it, they cut the spring inside the boot that keeps it from collapsing too far back, and I developed a split in that area - on the underside where it wasn't obvious! A trip to a Z yard got another for $25, and I did it the correct way - no problems now. Quote Link to comment Share on other sites More sharing options...
Garrett76Zt Posted April 2, 2007 Share Posted April 2, 2007 I'm a little curious why you wouldnt have seen a change in AFR's? At the same boost level that turbo should be flowing a good bit more air. Quote Link to comment Share on other sites More sharing options...
proxlamus© Posted April 2, 2007 Share Posted April 2, 2007 I agree w Garrett.. when I changed from the T3 to the Holset my whole map had to be vamped. BTW - notice this thread is 2 years old? Quote Link to comment Share on other sites More sharing options...
(goldfish) Posted April 3, 2007 Share Posted April 3, 2007 BTW - notice this thread is 2 years old? And here I was thinking he had that on the eclipse. lol, that sound like fun. Quote Link to comment Share on other sites More sharing options...
Brad-ManQ45 Posted April 4, 2007 Share Posted April 4, 2007 Since he's using the stock ecu/afm, no adjustment needed - if he were running speed density - definitely! I still think it is the afm to turbo boot - any hybrid I've seen you have to cut the boot back to enlarge the opening, and to do that you have to cut the spring. My car acted EXACTLY like he is saying - after you're off idle and accelerating you didn't know there was a problem.... Quote Link to comment Share on other sites More sharing options...
proxlamus© Posted April 5, 2007 Share Posted April 5, 2007 he was using megasquirt at the time =) Quote Link to comment Share on other sites More sharing options...
