nah not to thick at all pal its spot on and my car has ran miles better with it in

this below is an answer i got back off a guy who has owned and tuned gt turbos for over 12 years

i personally use fully synthetic (to cope with the high oil temps the gtt suffer with) and usually a 15w50 or a 10w60 as the engine is a fairly old design.

fully rejetted carb

Would the F2N and B18FT engines benefit from this grade of oil? I know the F2n probably won't get as hot but I've just had a quick scan in the haynes manual and it doesn't even mention 10W 40  :o  but 15W 40 and 15W 50..

could not comment on that one mate but id say the 15w 50 would be a good bet

hi mate yes its @16psi now i changed the main to 130 but some people dont ever change the mains and concentrate more on the second stage, iv got the ktec downpipe and machined/bored out turbo elbow to go on next week plus iv got this other t2/t25 .63 housing to go on which will be ran at 18psi so ill be looking at getting the carb and fuelling sorted again then

I have to question the high oil temperature though.

Mine has never gone past 100c even with enthusiatic driving and the standard oil cooler. Under normal driving conditions i might even say it runs slightly cool, usually the same as the coolant temperature (which would make sense considering there both intergrated in the same radiator) between 80-90c.

well i can well and truly say that the yesmobile is back taken the car for its first proper drive since dec 22nd today and boy did it put a big smile on my face cant wait to get the few bits done and have it back on the road properly at the start of march

i was going to get the t2/t25 .63 that i have fitted but im going stick with the t2 until it starts to wear and just add the ktec downpipe i have along with a unique gt motorsport turbo elbow , this will keep me more than happy for the next few months

took advantage of the decent day we had yesterday to give the car a good going over and mini valet inside plus pumped all the tyres up as they had lost quite a bit of pressure whilst standing, but on a sad note iv discovered it has hgf whats got to me the worst is that there are receipts for the head gasket and bolts from september last year so it must of been done on the cheap.

heres a few new pics with a pic of the filler cap

What is the colour of the oil on the dipstick?

That might just be condensation on the filler cap, even more likely if it's been standing for a while.
