Actually the oil feed for the turbo on the A-series is direct from the oilpump and UN-filtered. This is something that I have never considered. However, if you look at the history of metro turbos, the turbos are still going strong when the metros have rusted away, so probably not a big issue.

My 998 turbo that I use on the road is built on a 70,000 mile engine and gearbox, that has not been touched from the day it left the factory. Up until recently it was used every day and in turbo guise has covered over 8000 miles with no problems. As for performance, it has an estimated bhp of 80 to 90 and runs a 16.2 1/4 mile, this is a 0-60 of arouns 8.5 seconds. The conversion cost less than £1k (but I know what I'm doing and already had mapped ignition, which is cruitial to the conversion). see here http://www.turbo-mini.com/62147.html

I thought the original turbo oil feed was a banjo fitting off the oil pressure switch? If it is then the oil is filtered

[Wil_h]

Is it?

I thought it went pump-pressure reg-pressure sense-filter-bearings etc.....sump.

I'm happy to be wrong though.

[mini13]

yep its definatly filtered.

Well, let me put it this way... you wouldnt run a turbo off your gearbox oil in a modern car would you? Its probably the most rediculous peice of automotive engineering I've ever come accross. An afterthought botch is what it is! I'm not saying they dont work because they do, and im not saying you cant get good power out of them, because you can. What I am saying is that its not a good idea for a daily driver, longevity IS the issue and they are renound for their lack there of. Maybe if you ran some kind of stand alone slosh tank you could avoid the swarf issue, i dunno, its too much of a headache... stick n/a with the A-series for my money. Having said that, I cant comment on the charger route as its not something im familar with, other than they're expensive and require plenty of fettling...

there are loadsa turboed minis running fine.
what you say may be right but everything about that engine is a bodge job!! it started as a side valve in the 50's so its been modded an modded over the years to keep it being up to date, your comment about the oil may be right, but who makes an engine the way the a-series is set up nowaday anyway?? no-body because its had its day!! doesn't mean these things dont work!!


you could say running 1380 is daft because of the room inbetween the pistons, but it works fine!!!

i dare say you 0-60 is substantially lower than that if your running a 1/4mile of 16.2 what was your trap speed??
civic type R's only run 15.8ish and they suposedly do 0-60 in 6.5-7 seconds but go on to 150 so will keep powering through the 1/4mile you'd have a much better 60' and be running outta puff by the end, surely?? still respectable time.

p.s put it this way i know a lad with a 106 that ran a 16.2 ish last year @ USC and his 0-60 was 7.3 seconds!! if your mini does that, its rather nippy lol

0-60 can be high with a low ET, its all to do with the gearing

My 1400 did 1/4 ET in 16.5s and the 0-60s were all around 8 seconds

i know!!
what was the trap speed of yours for that??
i'm beggining to think the type-r's 0-60 is dreamland figure, as i've ran 15 second with a recorded 0-60 of 6.8 (have had a slightly better run but was 60'd not 0-60'd!!!)
