mrbeige 0 Posted December 5, 2007 I've been perusing t'internet trying to find info on the cossie turbots, and there seems to be nothing anywhere. They all talk about the perfomance and specs of the cars, but not the A/R, trim, compressor etc specifications. Can anyone enlighten me?

VEEDUBBED 0 Posted December 5, 2007 Right,the 2wd cosworth sierra had a garret T3 turbo with a comp.A/R of .42,the exh. housing A/R was .48.Next was the 4x4 saff. version,same T3 jobbie with same A/R but had a modified exh. housing. That brings us to the Escort cosworth,1st series had a Garret (T35),T3/4 turbo fitted with a .60 turbine A/R and a laggy .63 exh. housing,next was the face lifted model that had a T25 Garret blower which was only good for small boost,not sure on the specs because i've never used those weeny turbos. Ford escort rsturbos also had Garret T3 turbos fitted,1st series had an oil cooled T3 .42,.48 blower,2nd series had the same turbo fitted but water cooled,much more reliable and less prone to cracking around the wastegate penny. Lancia delta integrales had the same Garret T3/4(or T35 if you like),Evo-1 deltas had the .60 comp. fitted along with an awfully small .36 exhaust housing,that explains the lightning quick acceleration.. Delta 8v intergrales had a Garret T38 fitted which was an exellent turbo but cracked it's(.63) exhaust housing easily. Volvo 240 turbos also had the same turbo as the 8v intergrale with the same problems. I've fitted all the above turbos onto my various T.16v mills exept the small T25 and they are all good,latest is a T3/4 .60 with a Mountune modified escort cosworth.63 exh. housing,360 degree thrust bearing,stagger oil ring and quick realise bolt holes. Let me know if you need any more info,i've played with quite a few turbos... Quote Share this post Link to post Share on other sites
mrbeige 0 Posted December 6, 2007 Right,the 2wd cosworth sierra ....stuff..... quite a few turbos... Cheers for that dude, its much appreciated. do you have any info on the compressor and turbine housing trims and inducer/exducer sizes? Or can you point me in the direction of somewhere on t'internet that does? Quote Share this post Link to post Share on other sites
VEEDUBBED 0 Posted December 6, 2007 They are the trims,A/R is the sistem used by Garret,.42 is the most common-rs turbos,volvos,TD golf 2,old montego TD etc. Garret T/4s had .60 copressor trims,T4s had .70 with anything from a .63 to a .108 trim for the exhaust turbine side. Look on vwvortex in the forced induction area,good info. and people who know what there on about,Killa(paul) is especially clued up on FI. Check out junkyard turbos,another good site for info. on turbos Hope that helps. Quote Share this post Link to post Share on other sites

I was under the impression that Trim = Exducer dia[sup:5z2qiwsu]2[/sup:5z2qiwsu]/Inducer dia[sup:5z2qiwsu]2[/sup:5z2qiwsu] x 100 whereas the A/R = turbine inlet area/distance between the centre of the turbine wheel and the centre of the inlet or the same for the compessor I could of course be completely wrong :? I'll check out vortex and junkyard turbos. Cheers for the info though :D :D Quote Share this post Link to post Share on other sites
