Building a GR4

Wow!!
That looks like some intense metal work.
Keep us updated, progress looks great!!

I just read your "old discussion" on this build and amazed at the amount of work and time you have in your project. You are very talented. I am looking forward to seeing more.

Are you still planning on integrating a roll cage into your car? Once again, great work.

This car was renovated in Sweden 8 years ago.. As you can see the job wasn’t the best so I have to build everything. Sad thing is that he cut and removed so much so it’s hopeless for me to build it back to stock. Probably too much beer in his garage!!

I have bought pipe bender and a lot of pipe so roll cage will come. Not sure if it will be a full roll cage yet.

You may consider one of these roll cages. They seem very reasonably prices at 550 euro.

Roll cage

Thanks Push1267! Not bad price at all. Will see what I do when I come to this point.

which vender did you get the flares from? did you have to do lots of tweaking to get them to fit right?

Think it was from Patrick. He told me them original from the DT factory. Fit very well!

Can you provide some contact details for Patrick please?

Hi, It was Roland Jäckel how sold this to me. You can find him on Facebook, Think him on this forum also.

Then it's time for a little update .. The lower part of the front is finished and the exhaust outputs is filed in.









Most of the job's under the car is now finished so I'll will start test fitting the engine and trany

Today I got the engine and Ricardo gearbox in place ... Had to cut little behind to make room for the gearbox but it did eventually go in

That transmission is huge. Just curious. How are you going to maintain the structural integrity of the rear end since it looks like key pieces have been removed? Engineer a piece to go over the transmission?

More pictures of this ambitious project - please. I admire the confidence and courage you have to take this on. Very impresive. I too am interested in how creative you get tying the rear end together again. Almost looks like you could weld a flange on each side and bolt it to the tranny.

Haven't got to that part jet.. just cut it 6 hour's ago. Half to make new motor mounts so the engine and gearbox sits lover in the chassi. I will build a roll-cage and a frame that will hold the gearbox and stiffen the body/chassi. As you can see I have some hour left

Jt her are some link's to some pic:

GR4

I'm curious why you chose to go with a Ricardo gearbox, as they are no longer supported and spares are becoming rarer.

I bought the Ricardo 3 year's ago. This is a brand new unit so I don't see any problem with this unit for many year's. The internal parts are in other Ricardo units so i don't see any problems with getting parts.

So why did I go for the Ricardo... This discussion you will find on this forum and other forums like the GT40 forum. But for me this is a new and modern unit with smooth shifting, can withstand a lot of power and they are cheap.

I looked at many different unit's and they cost 3 times as much for a unit with same spec and then I also had to do many mods to get the unit in.

ZF is a good box but with the engine I went for it's just to small and parts for the ZF is to expensive to change every year. I want to use the car without thinking of breaking the box. and parts are cheep in England where I bought the unit.

Today I finish the new engine mount in alu. About 2" lower than original. Had to make a jig so the hole match with engine and chassi.

Hmmmm- your method may have been simpler. A few years ago I sectioned my motormounts by an inch about halfway down the lower half, to drop the engine so the Aviaid wet-sump pan was level with the lower edge of the frame rails. Dropping the engine more than an inch caused interference with the under-engine crossmember and the harmonic balancer-to-water-return pipe as well as the A/C to right frame rail clearance. In race cars, none of those would be a concern. Nice work.
