R5 GTT 172 Project

[James5]

Ok, thought it was about time that I added some information to the project section as to my recent start of a 172 conversion into the my little R5 the only reason for the conversion is I felt I ha got as much out of my C1J as possible and fancied a change so i have gone for a newer bigger engine with the intention to eventually turbo it.

Some pics in here https://www.rtoc.org/files/?path=Technical%20Files/James5%20-%20172%20Conversion/ will add more as i progress. I plan to be up and running fully by January 2009 to attend a www.cliosport.net R&R day @ chobham

Many thanks to Scoff & Ashy for the all advice.

Nice one bud. Im sure this will be cool when its done.

Happy b-day btw

Cheers matey

[Ashy]

Good luck matey, getting the bits together is the hardest bit. Once thats done it'll be a doddle It'll be fecking loud tho if you do go for the sidey!!

Happy Birthday

Cheers for the Happy Birthday

Got all the bits together now it's just a case as you say putting it together got myself a different fuel rail to use today whilst down the scrappie needs a little modifiing but should be good.
Going to see what the 172 lump is like with the powerflow sidey if it is really loud I may change.

Modified Alternator setup

[Scoff]

looking good

you can use a 16v clio rail too. you'd still need to make brackets.

you not using standard injectors then ? I thought you were using standard managment.

Yeah am going to be using the standard rail and injectors when in NA form but just gathering bits for the turbo conversion when I come across them.

iv just sold 4 wossner pistons i bought when i was thinking of doing this , only got 100 quid as well

[c7borg]

Cool, I'm interested as I'm doing the same starting in the next couple of weeks

All the alternator bracket stuff adds up, can't you just use the R5 GTT alternator and bracketory?
I may have to bite the bullet on the GTX front engine mount GTX front engine mount plate unless I can get lucky at a scrappy

The Alt brackets and mounts have cost a fair few ££'s to be honest I could prob have done some PMT work as you could prob drill out the standard GTT front mount bracket to fit the F4R block.

But with the Alt arms / brackets it will prob be just a case of playing about with what you can get to fit if not you will need to go down the same line as me or the clio 172 cup setup which is similait just different brackets and costs alot more than I paid for the GTX versions.

[Matt Cole]

I wish i could have just gone and bought an alternator bracket for the 225 lump! Took me half a day of grinding and fettling to get something right and lined up to work!!!!

[Os8472]

Looking good there bud, nice work

[Ashy]

As Scoff pointed out to me when i powder coated my plenum, you need to make sure the contact points on the bottom of the coil pack are clean metal to metal

Finally managed to sort out the phase 2 plenium with the phase 1 cable throttle body with some drill and tap work and fits perfect now, just got to get the engine in the car now

[minty83]

good to hear james keep up the good work

[Andrew Cooke]

What's the sticking out corroded thing on the front of the engine? do you need it?

[Adey aka Ewok]

fuel rail guard, and no you dont need it really, ment to protect the plastic rail on a front impact in the clio

[Maka]

How much for the bike????

who jiggered the ECU? Did you get a drawing showing which bits of the loom you needed or could ditch?

[James5]

Unfortunalty when it comes to the wiring / loom it's going to be a case of me playing with a multimeter and power probe, wiring I am not to bad at all I need to prob get it running is permanent ecu live, ignition ecu live, cranking signal, fuel pump wire (from relay on 172 phase 1 engine loom) then the rest will just be the gauges,etc...
ECU apparently demobilised by RStuning according to the receipt will find out when I finally try to start the car if it works as I purchased it used.

[Scoff]

James, shame your not closer by, I'd be pretty interested in having a nose inside that ECU, making some comparisons with a standard one!

[Andrew Cooke]

try and document what you do with the loom. You never know, it may be of interest to someone.

I will open it up and get some pics uploaded in the next couple of days, I also have a standard phase 2 ECU aswell I will open and get some pics.

I am one step ahead Andrew and am doing a how to guide as I go along for the N/A conversion and will be noting all of it to help others out as I doubt very much I will be the last person to do this conversion.

And a big thanks to Scoff and Ashy for all the advice and help they have given me.

[Scoff]

Nice one james. It's probably not a visible alteration, I'd be interested in knowing what the programmable devices are inside of it. Or, it may be really easy, and it'll be something visible

[James5]

Well just taken both the ECU cases of to have a look the 1st pic is the Phase 2 ECU and the 2nd is the Phase 1 ECU both look different in layout but I can't see that it looks like they have been touched physically.

[Scoff]

james, can you give me the make and part numbers of the ECU's you have ?

[Ashy]

I've got a spare phase 1 ECU in the garage if you wanted to have a play?

[c7borg]

Finally managed to sort out the phase 2 plenium with the phase 1 cable throttle body with some drill and tap work and fites perfect now, just got to get the engine in the car now

This is one of the issues I need to deal with.. I've got the later 172 engine with electric throttle body and need a cable operated one.. so did you use a volvo cable throttle body?

[James5]

Hi mate I am also using a later engine 2004 plate I ended up using the phase 1 172 cable tb by drilling and tapping the phase 2 plenum. The volvo jobby needs the same modification to the phase 2 plenium but you also need to modify the accelerator cam on the volvo by welding the lower part of the gtt accelerator cable fitment on . Scoff has fitted one if you need advice I am sure he will help

[James5]

james, can you give me the make and part numbers of the ECU's you have ?

Pic 1 is Phase 2

Pic 2 is Phase 1

[Scoff]

ooh maybe ?

james, can you verify there is a 29F200 device on the pcb, it should have 44 pins, probably made by AMD or Fujitsu.

[James5]

Just checked the phase 1 ECU and yeah AMD is written in it and it has 44 pins it is on the left of the big chip in th center.

Same chip on the phase 2 aswell

But this time above the big chip in the centre

[Andrew Cooke]

you gonna hack that ECU Scoff?

[Scoff]

thanks james. I could remove the immobiliser from that. that device is a flash/eeprom rom, it contains the immobiliser info.

ashy, if you don't mind me tinkering (and removing the immob) from that ecu then I'd like to have a go

[Scoff]

thats all that the tuners do, plenty of software about to do it, if you know where to look ! the software I have lists that ECU and the pcb pictures it has on file are the same as the ones james took. I haven't got a programmer for that fancy device though, my stuff is a bit old skool now. they're not mega bucks, I'd need to invest in one

[Scoff]

james, it looks like both ph.1 and ph.2 are both hackable in the same way.

good to know.

[Scoff]

james, just to clarify. is it the ph.1 ECU that has been modified ? I'm reading that the sirius 32N (phase 1) ECU needs the rom editing aswell as an emulator making and installing. is there any sign's of phisical intervention ?

looks like the ph.2 is the easy one.

[djinuk]

damn i didnt realise how much was involved in the 172 engine conversion, keep it full up 2date as im watching keen eyed best of luck

Yeah apparently the phase 1 ECU has been modified (it bloody should be) but I have got it in front of me apart and I cannot see any physical alterations to it Am getting a little concerned now. (Got to get engine in car and see)
The AMD chip number is
AM29F200BB
-70SE
0017FBB
1997 AMD

[Scoff]

don't let it worry you james, it probably just means I havn't worked out how they've done it, yet. they have probably come up with a more exotic way of doing it, my way may just be the long way round so to speak.

[James5]

The only way I am going to find out is when I plug it in to fire her up. Keep me posted on what you find out Chris

[Ashy]

No probs i'll post it down with this adaptor!
