Sprint and Hillclimbing

[rocketrichard]

After another brilliant day out at Goodwood I decided to try to increase my top speed and the cheapest and most fun way will be the addition of more horsepower.

I found a cheap ST170 and my plan is to swap that for my 1.8 zetec. Can anyone see major issues with this plan? I understand I'll have to swap the flywheel from the zetec and fit that to the ST engine as well as rewire the ECU.

Any advice will be hugely welcome.

No comments on the engine swap.

But I also have been thinking how to improve my results also.

My driving skills need to improve drastically but I am leaving power alone for now and am thinking about the cars handling.

One think I am looking at is fitting lightened flywheel, whilst it does nothing for top speed it seems to be most benificial at the low gears.

I have read a few articles equating each kg removed to static weight reduction and it is massive.

When you fit the lump it might be worth looking at this.

Off to sprints myself in five minutes

I'm thinking of the lightened flywheel when I fit the new engine. Goodwood is my local track and it's a power circuit hence the need to capture a few more horses.

Good luck today!

Won't say what happened but I was glad I had a full cage

So that's a roll or a heavy side-on. You can still type (unless you're dictating your posts for the ED staff to enter) so when's the vid appearing?

Neither John, can still type, still ran the other runs.

But I am thinking that I should install a GPS in the car or taking up cricket instead.

I also changed from a 2001 year 1.8 to a 2004 year ST170.  I was using the donor 1.8 ECU, clocks and the 1.8 wiring loom and fuse box from the donor

I used the st170 engine loom and ST170 ECU loom with the rest of the loom sections as per 1.8

Several wiring issues came up.

on the 1.8 the transponder ring on the ignition is powered from the ecu.  On the ST 170 the transponder ring is powered directly from the 2nd stage ignition circuit.

The ECU loom connector to fusebox has 1 pin swapped around,  it is the reverse gear switch circuit for the reversing light.

( GEM = General Electronics Module )
2004 ST170 electrics are GEM 2 and my donor 2001 1.8 was GEM 1.  The main difference is that GEM 1 does not control indicators,  that is all managed through the Hazard switch.  On Gem 2 vehicles the hazard switch is just that, a switch and you need a set of flasher relays for the indicators.

I kept the 1.8 clocks and they work fine on with the st170 ecu , I did not bother with the st170 pressure gauges.

Was it worth the effort , oh yeah...

Things to check on your ST170 , check the IMRC , Inlet Manifold Running Controller.  I had to rebuild mine.
You'll have to replace the donor manifold and down pipes and construct a custom cat by chopping and welding an aftermarket job.

I suggest you consider a high pressure plate and organic clutch plate.  The donor 1.8 clutch will struggle if you push it hard

Good luck, if you have questions just ask.

Thanks for the heads up, when I run into trouble, I know who to call!
