not my actual engine but its whats goin in, minus injection.
mine is running a twin choke carb and 4 branch manifold good for 163bhp 178ft/lb torque

Isn't the original output of the S2K 240bhp? You'll lose 77bhp just from changing to carbs?

It's 106 miles to Chicago, we've got a full tank of gas, half a pack of cigarettes, it's dark, and we're wearing sunglasses.
Hit it.

RS2K not S2K However an S2K on carbs would be fantastic!

150 bhp from standard...

That'll teach me to read things properly. Head thoroughly put back in the sand!

yeah rs2k engine mate lol

the engine im putting in this originally came from a mk6 4x4 escort then i fitted it 2 my old rwd fiesta bin highly ported and manifold matched with a modified 32/36 twin choke weber carb, on its last rolling road it came in @ 162.7bhp @3850 rpm and 177.7ft/lb torque, since then its had a hew head gasket and 40thou skim which should easily see another 5-7 bhp,
id so like to go with sum 45s but that cost near on £600 so itl stay twin choke till i get sum numbers up or i may go bike carbs and megajolt as mine running esc at the mo,
id like to know what budget suspension mods i can go for, what poundage springs should i be best to go for???????

thanks

massive thanks to purplebargeken for selling me the interior,to say im pleased is an understatment, my partner and kids loved them once they were fitted, ill grab pics tomorrow as shes going to my lockup ready for the fitting of the engine and box, so plenty of pics, wants and advice seeking to follow

again thanks ken, great to meet you fine chap

This is a bit of a thorny problem!
Having been there (or at least somewhere very similar) with my GM powered 2 door car, I can say that spring rates and ride height have given me more headaches than any other part of the job.
My first mistake was to assume that the Vauxhall engine is about the same weight as a Sprint item and I fitted Sprint coilovers at all 4 corners. The result was a car that appeared to be on stilts with an undriveably hard rear end (rock solid would be closer) I replaced the Sprint rears with the standard Toledo units which softened it up (a bit too much) but didn't help the height much and (being on a tight budget myself) cut about 4 inches off the standard Sprint front springs and refitted them with standard Sprint shox.
I know this process is frowned upon but I was Skint and it worked very well for 6 months and 1000 miles before I splurged my life savings on a pair of ASP Gaz front shox. With these fitted with a new pair of standard 1850 front coils and the addition of a Sprint A/R bar I would say the front end is now just about right but I am still struggling with the rear.
The basic problem is that to decide what length and poundage to try, first you need to know what you've got! This information has so far escaped me despite me buying a full BL shop manual for the Tolly the data is not there so I have no baseline to work from! What I'm looking for (as will you be, though possibly to a lesser extent since you have the heavier 4 door shell) Is a spring heavier than a Tolly one but softer than a Sprint one and with the ride height reduced by 2-3" depending on how much weight you're leaving out!
My own (as yet untried) solution is to get another pair of expensive ASP Gazs' for the back and hope the stiffer shox will tighten up the rear end enough that I won't have to experiment with endless different springs. This however is NOT a budget solution with Gaz shox being about £100 a pop!

Here on cutdown Sprint fronts and Toledo rears



Here with the front Gaz' installed, I had to wind it up a bit from here as I nearly lost the exhaust about 10 times a day with it here!



Your problems MAY not be as big as mine for 2 reasons, 1) yours is the heavier 4 door model and 2) I've made a conscious effort to lighten my car which has compounded my problems but please also note that the official parts list only lists 1 rear spring for Toledos whether 2 door or 4 door which seems odd as there is a considerable weight difference (about 90kg) between the two!
The reason I haven't done the rear yet is cos of those MGF wheels which currently JUST scrape the arches on bumps! I'm having the lips turned up (along with a load of other bodywork) in the next few weeks so then I'll go for the Gazs' and drop the rear as well!

Glad to help out, the wider seats are pretty comfy. Nice to meet you all today.

Can't wait to see the piccies.

Steve, the MGF wheels, are they bolted onto stock Tolly hubs, etc? Any modifications needed? Love the look.

Cheers

Ken

Hi,

I have recently bought some MGF wheels, do they need any mods doing to fit the Sprint? I do intend fiting bigger brakes eventually, but for now will use the Sprint wheels on the road and the MGF on the track.
Do I use MGF wheel nuts (so the nut face profile fits the stud hole )

cheers Paul

The MGF wheels are the correct PCD and near enough the same offset for a Dolly, HOWEVER nuts are a problem, I used late Sprint hubs which are 7/16 UNF with some chrome cap nuts bought on ebay, these were advertised as for mk1 Escort! Ken, if you're still using the Toledo studs it will work but you need to find some similar nuts in 3/8 UNF which might be problematic OR fit Freelander studs to your hubs (these are supposed to be a straight swap) and then the stock M12 MGF nuts will fit.
As far as clearance goes the front gives no issues at all on lock or over bumps over a wide range of ride height settings from too high to too low and using 195/50/15 Yoko tyres.
The rear however is a different matter BUT mine has been made worse by 2 things, 1) my osr arch has a slight ding in it which reduces clearance and 2) The F rims came to me with a useable pair of 205/50/15s which are at least 20mm too wide for the rims (standard F tyre size is 185/55/15) but it would have been rude not to use them! The clearance issue is so slight that I think a reduction to 195/50s on the rear would solve it. (there is no problem with the rear inside face though clearance is close)
A subsidiary benefit is that bigger brakes are no longer so problematical as that extra 2" inside makes a big difference to what is available to fit!

Sorry for the thread hijack
Steve

pics as promised




again thanks ken, top man and a gent of hes word,

now this is where she turns into the triumph RS 2000








and how she,ll look when fully installed, please note this was when in my old race car


thanks 4 veiwing

bin chopping more bits off today to dry fit the gearbox, where the gear lever comes is in middle of the seat so a solution is gunna be needed there,
still awaiting the metal to fab the engine and g/b mounts., abit of minor modding to the old tunnel and that fit back in sweetly so i can retain the bolt in tunnel.,
pics to follow

thanks
