A Week With The Gt30

Made a few more miles with the new setup. All in all I think near 500 miles or so. Had some minor issues like a wastegate gasket blowing out and a few bolt coming loose but most has been sorted out now. The boost curve needs some a djustemnt. I will receive a new chip tomorrow with higher boost settings over the mid rpm band. This way the torque will be back on the level where it was with the T3/T04 turbo. The higher rpm band is extreme. The car just keeps pulling all the way to 7200 RPM. At

Gt30 Go

Last Wednesday evening I finished the turbo conversion on the V70R. After some initial test runs the wastegate wasn't working properly. Car went in to fail safe much to quick. Yesterday I drove the car to RICA HQ in the Netherlands, a 135 mile drive for me. Traffic was extrem and it took me a long time to get there.

R Out

Took the T3/T04, downpipe and manifold of the R. Cut the downpipe and fitted the downpipe to the GT30 using a kind of mould/dummy setup. This is the same setup used when I mounted the T3/T04. I connected the cut parts using tape. When all is in shape it will be tig spot welded. After that is will be test fitted when the turbo is in the car and when all turns out OK it will be welded using backing gas. After removing the T3/T04 it was nice to see that the parts looked pretty good for the time

Gt30 Must Go... On...

In Februari all the furniture and stuff had to be moved back. Also a lot of small things to do in the house. Late last year I decided to buy an old Datsun for a new tuning project. During the winter I have been working on the engine, suspension and drivetrain while prepping the car for approval. Last monday the car was finally approved so now I can start

R Modified

Picked up the R from the dealer today. Car received 2 modifications. One mod to prevent the famous sidestep issue where the rear of the car can make a strange sideways movement when driving over road irregulariities. Tested the car on the way home on a not so nice piece of road. Car went smooth all the way up to 137 mph. The second modification is an attempt from Volvo to fix the front brake noise. My car started making a lot of noise during light to mild braking during the summer. During the
