Fun at oulton park(kind of)

[MarkTurbo]

I've been doing trackdays for about 7 years now and my engine has done 132,000 miles and never been rebuilt, like others have said cooling is the main issue and an oil cooler is needed 100% ;-)

I'm running a standard turbo at its limit so probably around 320/330 bhp. I've got a uk spec radiator (thicker than the standard jap one) and a 19 row oil cooler and oil temps rarely go above 100 degrees even in a 20 min session.

I only ever use mobil 1 motorsport 15/50 oil in my engine too, yeah its expensive but not compared to an engine rebuild ;-)

I use mobil 1 15/50 oil (very highly rated oil) as it is what it says, Castrol was sued by the US goverment for lying about there oil (they were not true full synthetic).

Mark you have now tempted fate and your engine will die!:lol:

looks like i am going to need new bearings, second hand crank, new seal kit, and a new conrod, bugger.
did think about cleaning the crank up and putting new bearings in without a full strip down so i can make it to cadwell in august but not sure.

 

[shroom]

would it be easier to buy a short block to get you on your way? as i know good cranks are hard to come by

sounds like you have been having some good fun reguardless hope you get it back and running soon

 

[bob the builder]

whats a short block?

 

[pulsarboby]

basically its a bottom half engine complete so you just bolt your head onto it

forget using that crank bob as it wont last you five minutes before it starts knocking again, be a waste of money for the shells etc and a complete waste of time altogether

 

[bob the builder]

bugger, i kinda knew that but just wanted to bury my head in the sand as i knew it was gonig to cost. big fat arse head.
oh well think i will pull the engine out tomorrow and start stripping it.

 

[pulsarboby]

just sent return pm bob....yes unfortunately you have no other choice but to drop the lot!
its one thing that you cannot lash up

 

[bob the builder]

where can i get a set of standard rings and pistons and some conrod bearings, is it nissan only.
will it be worth regrinding the crank or just bin it and get a good second hand one.(from you bob)
also new seals

 

[pulsarboby]

rings are either nissan or erics in the states, same with the bearings, either use acl or oe nissan ones

crank will be unservicable and only fit for scrap. besides its really not a good idea using a ground crank for a track based car as it will not last you long at all.
il see how many cranks i have in stock tomorrow but tbh i dont like selling them as we buy them in to use in our engine builds and havent got many, they are very very difficult to get hold of in standard good condition.
if your stuck though i will flog one on to you so at least you can get your car on the oc trackday

 

[bob the builder]

cheers bob much appreciated, will give nissan a ring tomorrow and see what the damage is.
just need to keep the misses sweet now so i can spend some money.

lol they like shoes and handbags:lol::lol:

 

[bob the builder]

well got the engine stripped down today.looks like there was only 2 conrod shells that were ok and 1 main shell that didnt have some damage.
but on the plus side everything else looks ok,

 

[fubar andy]

That's good to hear, just need it all ready for Cadwell Park now :-D
