ktown z Posted June 3, 2015 Share Posted June 3, 2015 Well I went to get my lady tuned today with 800cc injectors and gt2860-5s hoping for the best. The tuner stated he hears a knock and we are trying to diagnose it right now. It is not looking good. I hear a rattle in the drivetrain but the pros hear a knock. We will see. If I have to rebuild, I would like to change out my 5 speed RB25det trans to a VQ35/37 trans. McKinney makes a mount kit and there are adaptors available online. I have a bunch of questions. Do you think the VQ shifter will line up to the stock shifter location? My interior is all new and I don't want the hacked up look. Will I have to modify my trans tunnel to fit the larger trans? I know I will have to measure out the driveshaft but If anyone has done this swap, will my current driveshaft fit? I'm guessing a VQ clutch and flywheel will be needed. Is there anything I am missing? Thanks for supporting my 12 year obsession! James Quote Link to comment Share on other sites More sharing options...
ktown z Posted June 3, 2015 Author Share Posted June 3, 2015 Well I emailed Mac and got a very quick reply for all these questions. 1. The shifter does not sit in the stock location. It is about 4 inches farther back. 2. I will fit the trans tunnel. All tunnels are different so a BFH might be needed to persuade it. 3. A new drive shaft is needed. As far as the noise from the engine, I believe it to be a loose flywheel. At least that is what I hope it is. When doing the swap 10 years ago, I remember not using locktite and forgetting to put in the dowel pins. I also installed one of those "amazing" cheap xtd ebay clutches and flywheel. I know this is not acceptable but I was a kid and not very patient with my work. Times are different now. We did a compression test and all cylinders were 160 or above. That is fantastic! My oil looks good but I should send it out to get analyzed. When I get it back I will drop the tranny and replace the clutch/flywheel and torque everything to spec with locktite. Hopefully this will work. If not, 10k later and I will have a built motor. Quote Link to comment Share on other sites More sharing options...
