Turbo choice

I brought the car as a work hack, for towing a trailer and throwing tools in the back. I didn't set out to turbo a Commodore.. it just kinda happened.
Knowing :bow: Steve Murch of Motorsport engineering here in Auckland had something to do with it :whistling .. back in the late 90's I was playing with Rotaries..
I always wanted a big Garrett turbo charger.

Some "retail therapy" last year when my partner went overseas for work, I brought a Chinese T-70 for a song :dance:



It had been on a 13B and was in good condition, but Steve doesn't like Chinese turbo's and almost kicked me out of his workshop! hehe
I found a Garrett couple of months later, it probably is a bit big, but I had Steve modify it with an adapter to take a smaller turbine housing.


The T-70 on the left and the ex DAF truck similar to a GT42 on right




Compressor




Modified turbine (.68 A/R)

It worked out I ended up with an Ecotec engine.. so I swapped to it and sold the VR engine complete.. (I think it's in an RX7 down Wellington ways).
I wanted a better manifold too :thumbsup: (I've added Mace engineering's 69mm throttlebody and insulating inlet and plenum spacers too, which I noticed an improvement).

Also the Ecotec has slightly bigger valves, Beehive valve springs, better ports, lighter pistons/conrods, lower block deck height (weighs a little less).

I wanted to do a low budget (Oops!!) turbo conversion/addition and the Ecotech seemed a good base to do that from.

The Ecotec has good aftermarket bits available, some I used: ex USA zzperformance and Intense racing
and across the ditch Mace engineering, in Pukekohe NZ Adrian of Franklin cams, in Auckland: Turbo - thanks Steve Murch of Motorsport Engineering, Fabrication - Ronnie @ RSL Automotive, Glendene engine reconditioners (ripoff [email protected]$tasds), STA for gaskets and just about everything else!

The earlier non-ecotec has more aftermarket bits available ex USA it seems.
Oh I see where you are coming from there are a few advantages, Yes I know Steve Murch, he used to do rotary stuff in chch didn't he?

I had a "happy tappet" a few months back, after removing the rocker covers I found one exhaust valve had lost the tip off it down to just above the collet!
I thought "I can fix this", I removed just the one head, only to find the exhaust valves had recessed about 3mm into the head!! .. so after removing the other head found all exhaust valves had recessed.. not good.
So off to the Reconditioners they went for a crack test prior to me doing some exhaust port flowing with a die grinder.. annd like in the Lord of the rings, when Saraman said to Gandalf about the Dwarfs in Moria "..they dig too deep, you know what they awoke.." I went thru the roof of the port into the water jacket :cry:
So I found a pair of reco'd heads which I carefully ported, then drilled and tapped for 7/16" rocker studs for a set of Yella terra Platinum roller rockers and upgraded valve springs :yeah:
I'll post a pic, they look choice :dance:
But I've had a mission of a time trying to setup the preload for the lifters..
So I've decided to use Solid roller lifters, they're on their way from the states (same as LS1).

Yay! :dance: so should be going this weekend if they turn up
