My 79 scort + questions

79eskimk2 · 05-07-2007, 05:44 PM

hey all, finally got my car painted after a long 6 months of bodywork and such so here are some pics, tell me what ya think?

This is what it looked like b4 it got painted

and after

but she is a sad little eski atm.. the engine ate itself and its sitting up at dads in the cold, too kthe engine out the other day and opened it up, this is what i round..

so i went out and found another 1600 and hopefully this weekend itll be put in and running again. and i have a question about bolting on a small turbo for a little more go, maybe run 5-6 psi if i get the right info on putting one on. what would be involved in using a blow-through turbo set up on a 1600?
Any info will be appreciated.. thanks guys

A low blow turbo would be OK but in all honesty it will still never perform properly while the car is running on this crappy unleaded fuel we get dished up today. By the time you lower your CR (even for low blow and 98 RON fuel) the car will turn into a gutless wonder below 3500 rpm. The carby also has to be modified quite a bit for blow through and IMO not worth the expense or effort.

I have just (this very week) completed an LPG set-up on my son's (yes, I have finally passed it on) RS2000 and it is already prepared for a low boost turbo installation which I know he will be wanting to do in the not too distant future. The cost of the LPG install was $2500 and the govt gives a rebate of $2k - so for $500 the car now runs as good as it did in the good old days when we could get 100 RON fuel for our little rockets - and a bonus is the fuel cost per km is gong to be halved (estimation at this time).

So if you are serious about a turbo here's your plan ... convert to LPG and ditch the carby and use a throttle body off any EFI car you can find laying around at the wreckers - I used a 4.0L falcon one. Be sure to order a complex convertor (not a regulator and mixer) in the gas kit that will support a 3.0L motor up to say 200HP and when you are ready to add the turbo it will be an easy job - fuel supply already taken care of!

Good luck with it.

Looks tough, good job with paint.

Personal opinon, carby's and turbo's will never get along. You will for ever have hassels when runnning a blow through or suck through set up. Grab a sierra manifold, computer and convert to EFI. Make a turbo manifold, modify your sump, mount a intercooler and your pretty much done.

Not to sure weather I would go gas AND turbo. T3man - where did you mount the gas cyclinder? Does that add a s&!t load of weight? I also don't believe all EFI turbo cars are gutless wonders under 3500 rpm.

He spoke of low boost therefore an intercooler is only going to add more lag due to the length on the intake tract.

The LPG cylinder is in the boot behind the rear seat - I couldn't get an appropriate one that would fit underneath in the place of the fuel tank which was my preferred option. The weight is not too much of a factor - the car already has HD rear springs and Koni shocks - in fact, my testing so far has indicated that any change in the handling of the car is impossible to notice.

No, not all EFI turbo cars are gutless wonders under 3500 rpm ... eg. the BA/BF Falcons/Typhoons are pretty good. BUT this car is a 1600cc currently running a carby - my position is unchanged. Also IMO it is simply not worth the expense of running an EFI setup on this type of engine especially if turboing the motor is a possibility. The LPG road is simple, effective and CHEAP. Hard to beat eh?

Oh, and a pic of the engine set-up for anyone interested ...

Yes you are correct T3man, my mistake. I should of read the original post correctly, I thought we were talking about a 2.0L. So ignore my above post because basically none of it will work. My question now is why even bother turboing a 1600? But if you really want to it looks like LPG is right way to go. You could use EA falcon TBI and adapt it to the original manifold? But you would have to purchase a aftermarket ECU which kills the price!

I used a throttle body off an EF but the next car I do (Capri V6) is going to have a throttle body off a ZL (4.1 EFI). Any throttle body of any EFI engine will do the job. Adaptors are easy to fabricate if you have basic skills and tools, and some time on your hands. If not I'm sure a local engineering workshop could fix something up for less than $100 labour plus material cost.

As for the ECU, totally un-necessary if you go LPG. I just dumped the entire petrol system entirely. The engine is therefore able to be tuned exclusively for LPG and it responds beautifully. The low down response and torque is amazing compared to the original petrol motor. However it has lost some power over 4500 RPM but is still no slouch. That is just a function of the very long inlet tract the motor now has, combined with the cam profile which is not a specific LPG grind but a high performance petrol one. I'm sure the top end will liven up substantially once my son puts the turbo on.

nice job with the motor...

I'm amazed at what people are doing with old cars and efi/turbo etc....I must admit, I'm a purest when it comes to old school Mk 1 Escorts and Capris, but you have to admire this sort of work. Well done.

Mate for years I was the same as you - purist I mean. But after many years putting up with the cars not being able to be tuned properly on the really poor fuel I have in my (country NSW) area I decided to do something about it.

If the cars were only show cars or lived in the shed 90% of the time I wouldn't have bothered. But because I love driving them so much and do so at least a couple of days a week I couldn't live with the poor performance and very high fuel (plus additives) costs any longer.

The LPG conversion turned out even better than I ever expected and I would recommend it to anyone who is using their Esky as a regular driver. I'm so happy with the result that I will be doing the Capri as well in the very near future.

PS. I have kept all the original parts to hand on to my son if at any time in the future he feels the need to take the car off the road and fully restore it to original running gear. It's his baby from now on.
