We just ran a freshly rebuilt T2 motor on the dyno (with a few mods, standard cam and valves, rods and crank). In an untuned state (ie very rich due to the big injectors it pulled over 100kw at the wheels (134hp at the wheels). For a comparison a 3.0L turbo 6 (VL commodore) pulls 90kw at the wheels. Not bad for a 1231cc CVCC motor with 30mm intake and 20mm exhaust valves huh? That was at 20psi of boost. Now we have to fine tune and throw in the 50hp of NOS. We also have 2 hotter cams to try. This motor still gets 30mpg economy around town (with no light foot either).

Oh yeah it was also 32 degrees C and 90% humidity. We do live in the tropics after all.

hey charles is that the same turbo set up we ar talking about for my engine?

This is the actual ER/City turbo motor. It is only a 1200 and has tiny valves. The motor/hybrid we have been talking about should have more go!

HYBRID?? PLEASE EXPOUND ON THAT!!!!

By Charles (137.219.16.107) on Sunday, February 18, 2001 - 10:17 pm:

Somewhere we have been discussing the ER manifolds and induction on the EJ head on and EJ/EN/EB block. This give an all alloy 1335cc (min, up to 1440cc), big valved version of the city turbo motor that can rev an extra couple of thousand rpm.

As I said the ER turbo has tiny valves and a long stroke. Boy it makes some torque and consequently quite reasonable hp. To drive the thing is rosy until 4000rpm in any gear. If you let it get to 4000rpm in first then wheelspin to redline is instant as it is in second. It spins the wheels at 110km/hr in third when it comes on boost. A hybrid would be a real blast.

Cool ;)

Charles; I must be missing something! All i have are US engines, 1200 EB, 1300 EJ, 1500 ED, 1500 EM1 (80-83), 1600 EJ and the 1751 EK1. I've tried placing the 1200 head on the 1300 block and doesn't 'fit' at all! (well except for the head bolts) to where it would run!

What i've been looking at is stroking a 1300 engine with a 1500 Em1 crank/rods and the 80-83 EM1-4 port exhaust head (still can get headers) and the combustion chamber and valves are larger (even the aux valves) to lower the compression a bit. I just don't like the 'fire-ring' on the 1500's head gasket looks like it woud rest on the aluminum wall intead of the steel liner. Now if i can make some supports to weld in..... I would feel better. And btw, are you running forged pistons??

By Charles (137.219.16.107) on Monday, February 19, 2001 - 03:36 pm:

Having never seen an EJ engine in real life other than talking head dimensions with those that have them I was not aware that the head did not suit the EB block. I thought it would be the same as the EN/EB swap in OZ. However it seems I would need an entire EJ to do this swap then.

The EJ valves are waaay bigger than the ER valves and I think a properly sorted EJ with the ER turbo manifolds would go very well indeed. Another engine that would benefit from the turbo conversion is the EK. The turbo system almost a direct bolt on!

The ER motor mentioned above is running forgies and total seal rings as well as complete ARP bolts and studs all through.

talking about heads, does anybody have an EG1 or EL1 head? is this the right head to do the swap on an EK1 to ditch the CVCC stuff?

I need to get the casting numbers off the head that I need and I've got a guy that can do a search for this head.

Errol, I think you know what I'm trying to do, I have that intake manifold from Ebay (takes a DCOE or Mikuni PHH carb) and I'm going to get an exhaust header from Impact Parts, and then with some magic hopefully bolt it all up onto a '79 EK1 block.

Am I heading in the right direction, or am I pissing in the wind thinking this will work???

I wouldn't mind hearing more about this turbo system for an EK, that might be a way to go too.

Charles you just threw my idea of a 87 engine swap out the window. i believe i will stick to our idea of the ej hybrid. is it still going to work you think? any way thanks again for all the help Charles.
Godspeed,

A.W.

By errol (152.163.197.68) on Tuesday, February 20, 2001 - 07:56 am:

Paul, Is that a 4-port exhaust or 2-port exhaust header from impact? and how much?


Charles; I'm going to look at the combustion chambers today and see which looks better

By Paul Krummenacker (216.26.39.192) on Tuesday, February 20, 2001 - 08:02 am:

Impact has a 4 port Canadian exhaust they are blowing out. they say it won't fit a US car, but they don't say in what way it won't. They want $35 (I think) for the header, I figured it was worth giving it a shot.

My only concern is that I'm heading in the wrong direction with trying to get more umph out of my car. so, if anybody has an oppinion, please tell me.

Hey Paul,
Check out the thread "250hp 1800 TURBO" If you are serious, I think that Charles/Racecraft can do it. There is one bolt on the 81 EK1 CVCC head that would have to be relocated, but from preliminary investigations,I think that is the only problem.
Imaginge a TURBO 1800 !!

Paul; could you please mail me thier number??
