I want them to suit 86 mm bores and 89mm bores. I will go to the wills site and give you some part numbers if possible.

What sort of pumps do you service/sell wilson-snyder, geho or similar?????

yeah i agree fm, but this is not a SERIOUS engine, its just a bit of mucking around really, the turbos are cheap but too small so its easy enough to just use 2 of em

it may turnout to be serious but in the end im just foolin round till i have enough cash flow for the CA18DET conversion

so yeah, im at uni at the moment and just trying to do it on the cheap, therefore hoping not to rebuild, the motor i have is only 20,000 miles old anyway i was just hoping that o-ringing would be any easy way to insure against blown head gskets, apparently it is not in my case

Your words are good advice
Do the homework first, do it twice if need be & get it right the first time to avoid regrets.
Thanks for the support.

The company I work for source them from England. We carry a good supply of spares here for various pumps etc....what size are you after.

I've always had to go to England to get wills rings.
You could try Randal Edgell (edgell automotive) in Auckland. Randal is not scared to write out an invoice however!!!

Actually, although I've never tried to turbo an A series, I gave up o-ringing the A12 when I discovered the NISMO headgaskets. I never managed to blow one, despite the neglect and abuse...

Dodgeman has a good point !
This thing has 2 turbos RIGHT!
Right,well then this engine should`ve been built with some serious BOOST in mind.
This is not intended to insult anyone,but don`t you think it should`ve been done
right the first time ?
This saves a lot of headaches afterwards,as you`ve already found out !

Dude bite the bullet,strip it down and while it`s apart give everything a good clean & inspection. This could only have a positive effect such as "PEACE OF MIND" and a Lesson well learned !

GOOD LUCK

How easy are "Wills" O rings to get in NZ?

I am having trouble getting them here in OZ and my mails to the UK parent company go un answered???

They are the best sealing method for very high comp and boosted engines

It depends on the type of o ring used. If you use wire a trepanning tool centred in the bore can be used like Errol said but if use want to use Nitrogen filled "Wills" O- rings you may find it better to strip the block. I have done them in place and had no problems.

Is this a street engine, or an all out competition engine?
If it's for street use, then why on earth do you need to "o" ring it?

If it's an all out competition engine, then pull the whole bloody thing down & do it right.

Ferral Errol is right about the rag plug etc. but, if it's a STREET engine, & if you are having head gasket problems, then fix the ACTUAL cause rather than wasting your time & money on "O" ringing the block.

I had a home made cutter that centred in the bore and was hand operated on a screw feed that could be manually adjusted. This was done in the car.

All you had to do was make a rag plug in the bore and coat with grease then block all the galleries with grease. The "O" ring slot is only 0.040" (1 mm) wide and 0.020" (0.5mm) depth for 0.040 (1mm) anealled stainless wire. This only makes a very small amount of cast iron cuttings.

Its not as difficult as it sounds.
