New GTV6 project, 1981 Rosso

With the oldest GTV6 nearing 40 years in service, a forum to document projects and restoration seems sensible.

New GTV6 project, 1981 Rosso

Post by Michael » Tue Sep 04, 2018 10:06 am

Hey guys:
Its been a long time since I've had a GTV6 to work on, I thought it high time that I start a new project.
I bought this car from Colorado, its a 'blue plate' N California car and I guess the best part is that it has no rust. Well, at least, I have not found any so far :-)
Anyway, here are some pictures:

The car is impressive, for 38 years old, the panels are remarkably straight! Total miles are around 140k but not too many of those have been accrued in recent years. I bought the car with a broken stock engine. I'm not sure what is wrong with it, but the previous owner overhauled the cylinder heads and the car never ran properly afterwards. In any regard, I'm planning on installing a 3.0 liter engine sourced from a Milano back in the late 90s.
I'm working on the engine currently, just to re-seal it. I'll then install it, get the car running and figure out what else it needs.

The front end pictures illustrate the need for some bodywork. The car has been hit in the front at some point and the front panel needs to be either straightened or replaced...

Shows above is a NOS front panel I found in Australia ... its quite expensive :cry:
In any regard, once I get the car running I'll be able to get some opinions from some body shops.

I'll update this as I go, next up - getting that 3 liter engine ready to install.

Oh hello there stranger, nice to see you back at home :D

I spoke to Rob a few months ago telling him to be on a lookout for a GTV6 for you. Good to know you now have one in hand.

Michael that GTV looks like it's pretty good to shape to be restored . Always so much easier when it's not rotten . Look forward to watching progress. Are you going down the route of Powdercoating all suspension bits and plating all the associated bits . Good that it does not have a sun roof as those are just rust traps.

'Restoration' somewhat oversells what I hope to accomplish, this is more of a 'get it back on the road' project. This car has no rust but it does have a bent front panel and driver side wheel arch, and has 140k+ miles on it so its never going to be a concourse winner. That is okay though because I don't want to be constrained by the need to keep it original. I'm currently working on getting my old 12v 3.0 ready to install, and its getting close. I replaced all the gaskets and seals and ended up converting to the 164 belt system using a 164 front pulley with 60-2 timing wheel and water pump. I installed a 164 crank sensor using the Verde front cover since it has the holes ready to tap. One day I want to Megasquirt this car and this will allow me to retire the distributor (or convert it to a cam sensor only).
Anyway, I used the original Verde timing belt tensioner, overhauled with new seals, but I filled the oil reservoir with grease to make it essentially a fixed tensioner. I don't exactly remember if this is all that is needed. I still have the spring installed between the sliding metal plate and the body of the tensioner (I think this sets the initial tension), but did not install the other spring. For setting the tension on the belt ... I loosened the retaining nuts & rotated the crank several times and then left the engine exactly at TDC. I then tightened the retaining nuts. I can just about twist the belt 90 degrees so it feels about right.
Any feedback on this timing belt tensioner implementation?

Hi Michael , I have been doing similar set up with tensioner for last 20 years and no failures ... Yet :)
I do however change the belt every four years regardless off mileage. I have never filled the tensioner with grease or stripped the spring out. I do set it with the spring compressed in the tensioner and a firm 90degree twist at tdc only and recheck after few rotations at tdc.
This is also an excellent option for not having to worry about grease and spring giving to much variance . See pic below of Oliver's engine by using small adjustable rod ends.

Awesome idea!
I'll duplicate this on my engine.

Anyone know what this box does?

This is on the passenger side firewall, just behind the dash, near the ECU.
I know the sensor for the catalytic converter was connected to it.

Is that a cat over heat sensor circuit?
