A mate of mine back in the 80s built a draw-draw set-up after I took him for a ride in mine. He had a hiflow T03/T04 hybrid sucking through an SU and he would wind it up to 24 PSI regularly. We swapped cars a few times, just for comparison, and his car pulled harder than mine, as you would expect running the extra boost, but the responsiveness of the draw-through system was horrible. It felt like there was a rubber band in the throttle cable and the carby took a second or so to respond to the throttle being floored. Makes sense using a fogger NOS kit. Did you find this the case between the draw-through and blow-through?
 
I've got a 26661 grind cam which I have run without boost, but never boosted. What did it perform like and did you ever run a standard cam to compare it against?
 
I too in the end went with a solid centre button clutch on my 1st engine and it was not only the last clutch I bought, but the only one that held up. Took a bit of practice to engage from standstill, but once you got the hang of it, it was OK, but I'd never call it smooth.
 
Both engines ran their exhaust systems down the passenger side, just like a factory Escort. 1st engine was 2.5 inch non mandrel bent with only a single muffler in the original location under the rear seat. Sounded deep and throaty yet very quiet. 2nd engine was 3 inch mandrel bent with both a muffler and resonator. I had read that 3 inch systems were prone to droning, but I thought I'd give it a go anyway. Big mistake. Anything over 90 km/h and it was like driving while sitting inside a bass drum. I still have the full 3 inch system, which comprises a 3 inch dump pipe from the back of the turbo to about level with the top of the sump, then bolt on from there. Did it this way to avoid having the joining flange under the car due to already tight clearances. If I build another one I plan on using the 3 inch dump pipe then reducing to a 2.5 inch system from there and will just run it down the driver's side as I don't have a drop tank.
 
And I absolutely agree with you. If they are well built and tuned right no exotic motor is needed.

The biggest difference from draw thru to blow thru was the lag or lack of lag. No comparison . The change in driveability after changing to blow thru was phenomenal. Hence why i had nos on the draw thru setup to eliminate lag.

 
That's exactly what my mate with the draw-through set-up said after taking my car for a spin. The difference in response is night and day.

My first engine started off with a steam pipe manifold topped with a turbo off a factory Nissan Bluebird running the standard internal waste-gate. I then bought the Garret split-port cast manifold and T03 with the external waste-gate and fell in love with the in-cabin adjustability. Not sure what ID pipes are used in the manifold I've currently got, but it looks pretty much exactly the same as the first manifold I had made, only with an external waste-gate.
 
This is about the best photo I've got of my current manifold with the waste-gate visible underneath.
 

 

TT331The 26661 cam responds well to turbo charging due to its wide lsa of 112.

Interesting you say that. When I was looking into forced induction I found a bit of info from the Swedes at Skogen racing. The crow 26661 specs match up perfectly to the cam they recommend for turbo application

a few interior shots it uses the factory 6 dial dash new door cards from aldrige trim in uk and omp bucket seats as the factory front seats needed major work to restore. Suprisingly the back seat is still the factory 1970 trim and material just replaced a small section of it across the top where it was cracked and sun damaged.

Chuff,

Pistons used in the 178kw build
Were acl duralite pistons. Still cast but they have a higher silicone content some may call these hypereutetic

The efi intake i used is a 4 barrel spearco .
Have welded 4 speedflow injector bosses in each runner. Managed to track down a NOS vortech intake elbow.
Welded a throttle body flange mount to that . And will be running a foward facing elbow with a universal 70mm throttle body and a nissan t.p.s

Ignition i am using is a 4age toyota distributor with a cas and a single tooth home position sensor for sequential injection.

Running single coil and a 4age igniter

There is a fair few mods to do to the pinto distributor to get it all to work.

Will post some pics to follow.

The throttle body trial fit




Distributor modded pinto bottom half for oil pump drive and 4 age top half it also runs the 4age cap
