It's great to see this project nearly there. I've followed it for years and I'm really glad to see it running down the road. Keep up the good work.

The picture has worked (sort of). It will need double clicking as it's a thumbnail image.

Hi Loyale 2.7 Turbo. I would post a photo but I can't work out how to do it. I Can't find the "Add an album" link in my CP. Any suggestions?

Hi Folks. My 1976 GF hardtop with EA71 has the redline starting at 6400 RPM. I have had it as high as 7500 in car club events but it was much younger then.

Hi, the pistons have to be screwed in because of the handbrake setup, using the large slot. The trick is to make a flat driver out of steel that matches the width of the slot and turn it using a shifting spanner or similar. They can take a bit to get them turning, Good luck, Howard

Hi Kostamojen. Some years ago I fitted EA63 GSR Heads to an EA71 crankcase. The water galleries didn't line up and the heads had to be modified to suit the 1600 head gaskets. Everything looked and worked fine for years, but recently I decided to rebuild the engine and when I looked at the old head gasket I was amazed to see that at one place there was only about 1.5mm on the headgasket sealing ring between the water gallery and the cylinder (it's a miracle it held but somehow it did). Long story I know, but are you sure that one of the water galleries in the head isn't too close to the cylinder as can easily happen when heads from one model are fitted to the crankcase of another model. I have since rebuilt the engine but had the offending galleries welded and reshaped away from the cylinders. Just a thought. Good luck, I have followed this thread from very early on and your doing an amazing job.

Hi two85s. I assumed it was something to ensure that the lip of the seal was protected to make sure it didn't fold back during installation. regards, Howard

Hi all. Old thread I know but what exactly is a seal protector? Thanks

Hi Giant. There is a Nylon? bush in the shift linkages and if this is worn will make the shift very sloppy. This could be the problem. It is a very simple bush and may still be available but if not would be easy to have made. regards, Howard

Hi Dirk. It may not look big but it is quite heavy. I had mine lightened by about 20% years ago and the engine revs very nicely. It did seem to make a difference in responsivness at the time but after all these years it just seems normal. Anyhow if I was you I'd do it. regards, Howard

Hi tailgatewagon. Yes it is an early EA71 with the external water crossover, Kiwi subbie. I have a 40mm DCN Weber carby which was running a bit rich so economy was not great, about 11 litres per 100 klm. Performance wise it was great, just felt like a bigger GSR motor.

Hi. I have also successfully put 1400 GSR heads on an EA71. The studs and pattern were fine, the only problem I came across was some of the water gallery outlets in the heads. I had the heads welded and the outlets angled further outwards from the cylinder liners and had no problems. I also had a bead of weld added around the edge of the heads to better fit the crankcase. A light skim to level everything, and that's it. Just remember to re-torque the heads after about 15 minutes running. Another problem is the compression ratio. My compression tester showed approx 195psi per cylinder which is a bit on the high side. I am in the process of doing a full rebuild after about 12 years and have skimmed 1/16th off the pistons, which the engineers tell me should be fine , to lower the compression a little. I'll let you know how I go.

Hi GeneralDisorder. My main problem is the diff ratio. It's a bit of an odball gearbox which came from Japan on a EA71 with twin carby's. It's OK around town but on a trip 4000 rpm in 5th equates to about 60mph which makes it a bit of a buzzbox. The original box which died had much longer legs and had simlar gearing to my XT Turbo. I have just rebuilt the EA71 which is in a 1976 GF Hardtop and was hoping to get back to a standard ratio. Any other suggestions. Thanks
