please can some1 post any differences between the mk3 and mk4 turbos running gear.

not after engine info or box info. but the suspension setup, track setup, roll bars, ect.

im planning to convert a mk1 orion into an rst s1 in apperence(within reason obviously!), and have an efi rst to fit complete with loads of other goodies. ill be needing a full s1 setup to add to the car, but as s2 is more readily available ill want to know what i could use from the s2 if anything.

also any detailed pics underneath a s1 n s2 would be great!

cheers

as its a mk 1 onion u will need a s1 or 16i antiroll bar which means u will need a mk3 gearbox due to the mounting points, u can use s2 suspension, brakes etc...

s3rst

the car is a 1.6 i. so basicly its the same as the s1 then? but turbo shock n breaks from either s1/s2 will fit? does any1 have pics of the 2? i do have the s1 box too and aware of the mounts different to s2.

JesseT

It will have as standard the same brakes, rear anti-roll bar, uprights, steering, etc. etc. What is different, is the front anti-roll bar arrangement and springs. Schocks are also different, but not necessarily any better or harder. S1 came as standard with softer dampers and heavier springs than the XR3i at least.

Oh, and change the engine mounts as well. Ive ripped a number of Orion mounts to peaces and the standard oil-filled mounts are really expensive. I believe deflex do good but affrodable mounts nowadays. I have Vibratechincs S1 mounts myself in my Orion.

just checked yr orion out...looks sweet as! any under car/under bonnet pics?

and what management?! im making a hybrid of efi from variouse cars. what color red is that? looks sweet... mines baby blue.

s3rst

and so id need the front anti roll bar setup from a s1? what about the adjustable one from the rs1600i will that work?

JesseT

You don't "need" the front anti-roll bar setup. I tried it and changed back to the Escort 24mm unit from my XR3i. The colour is R5 "Rosso Red". It the original paintwork, never been resprayed. It's running a CVH hybrid engine, half from a mk5 Escort and half from a S1. Management is Megasquirt'n'EDIS. Here's two old bad pictures of the engine:

whats this mega squirt all about mate?

urve done what im doing... head inlet ect from efi cvh and s1 bottom end.

but im going to add the fiesta turbo ecu and engine loom.

so really just need to sort out some good suspension n mayby decent aftermarket discs n pads... thing is im looking at over 200 bhp when finished, its on 193 on mfi management as it is in the mk3 orion, so i will need bigger breaks.

i like the color... was going to respray white... not sure now

JesseT

It's a DIY programmable fuelling/ignition ecu the parts for which cost under 100Ł

If you're settling for 200, then you won't need much modifications

The RS1600i and S1 front suspensions are both adjustable on caster and caster only. The designs are similar with the RS1600i front end being a bit more robust and also harder to come by.
S2 brakes are an easy upgrade, but Cossie brakes are so much better. The small servo could do with upgrading as well.

more info on megesquirt pls!!!! im paying out 150 for my ecu and loom saterday... less is better lol.

well... the engine is fitted with l/c acralites,steel rods,arp bolts ect, lds, 4paddle clutch, hybrid turbo, got 193 at 14psi and it was running lean so bigger injecters and better pump on the remap... but whats the megasquirt?! would be intrested to c how easy to convert it. where do u get the signal for the spark? im using the 1.8 cvh tdc and pulleys

update*** forget the mega squirt... if parts cost me 100 quid id be better off buying for 150 complete! frst ofab is my chosen route... but sweet if u got yrs working for 100 quid!

JesseT

I'm using the standard efi flywheel and the related crank sensor for triggering together with the EDIS module to control wasted-spark.
Converting is easy if you have knowledge about how things work or don't care to find out. Time consuming, but highly rewarding it is in any case. I can't see the point from a money saving point of view. 150 is really not much for a ecu and loom (and other electrics needed?), but having a management you can datalog, live map and tune with and modify it easily to your liking is a great benefit.
