anybody got an idea of what sort of power i could get out my rst with a new turbo? and
what turbo should i buy??
here is a list ofspec so far,
+1 accralites, fully balanced bottom end inc clutch and flywheel,
arp rod bolts, uprated bearings, hp oil pump.
head has been mildley ported, althought the inlet manifold is not port matched, and the head poss has oversized valves i did now the size but carnt fin it at the mo.
285tcam, standard pulley and lifters
belived to be a standard turbo but dont know as it came with the car but it was new
k&n cone, pace cooler, grp a coil with motorcraft "7" plugs, superchipped ecu. new dizzy and leads all engine sensors replaced except airflow and emfp. boost is currently set at 14 peak and holds 12.

what power do you think it should have?
what new turbo should i get? and what power may it make then?

thanks for you help

 

probably has 150-170 at the moment, with 17-20psi you should have 180-200 brake (@ the crank), depending on who sets it up..... but be prepared to use lots of petrol

 

Yeah as above really, fit a Stage 2 T3 and you'll see closer to 220bhp (fly) fuelling allowing.

 

true... when does a standard t3 start running out of puff?

 

dont know but mine use to peak at 20 when i got it but it never held it there, never held more than 15 i think.

 

It will flow enough for a genuine 190bhp'ish (fly), Stage 1 is pointless as it doesnt flow any more, Stage 2 will do 240bhp'ish with good mapping, and Stage 3 will do 270bhp'ish IIRC!

 

anybidy know whats the biggets turbo is safe to use and whats most power i will likley be agle to get?
thanks

 

Doesnt matter, your stil MFI so your fuelling is your limiting factor....
Go EFI and the sky is the limit mate!

 

will efi be decent ish on fuel, 10 years ago my s1 was harsh on fuel, mind I earn double now but have double the out goings

My turbo cabrios pretty standard at the min, and is decent on fuel driven sensibly

But will soon be cossie managed

 

EFI will be far better on fuel than any 20year old MFI setup, as the ECU will only supply as much fuel as the car needs at any load point if mapped acuratley of course!

 

I should find out soon enough, gotta have it converted before central day at santapod in april, so best get my finger out, starting with fitting the cam kiton friday

Hopefully the last time it will ever run on mfi
