Is this fixable?

[Ako]

Ok.. I'll get photos up soon as possible, but long story short - the wee motor I've gotten hold of died a horrible death.

It once was a 2.2 stroker - 2 bar of boost through a T78 without enough fuel ensured it blew a chunk nicely off the ring lands on both cylinders 2 and 3.

So, once I get the $$ for my VR4 through, I'll be getting the fancy bottom end being sold on here. Problem is, I want to keep the head I have now - its had some serious porting done to it, and would be an absolute waste not to use it.

Now, when the pistons cried foul, of course the little blown off chunks have greeted the cylinder head. The valves themselves are fine, but there is some minor scoring on the head.

Question - can it be repaired? I'm a bit on the stupid side when it comes to some things Failing that, with the HKS cams which come with it, will it hurt me much NOT to use the flash head, and just go for a stock one? (Assuming its not fixable).

Cheers for any advice on this one

What sort of manifold does it have, the stock one still?

Depends on how bad the gouges are really, it might be ok or it might be junk

[Ako]

So its not reaaaally something which can be fixed up?

I'll have to get a photo for this one I think. Will have to get an MR2 knowledgable type person to have a look at it (think Al is coming to have a geeze tomorrow night).

You wouldnt believe the amount of times I asked the previous owner for more specs of it to no avail....I'm guessing it was built in Japan?

[Ako]

I'll give the specs of what I know so far (since its mine now I'm allowed to )

Errm... Its stroked to 2.2, theres no brand on the rods (!!!!) so theres one curious thing. Pistons, same deal, no brand name I recognised. This is going out the door shortly anyway.

Head - Ported to hell, HKS cams, dont know if its got adjustable gears or not though.

Intake - Still running an AFM metered system, got a rather large HKS side mount cooler, turbo is a T78 and rather large to say the least, has a custom mani with an HKS 50mm wastegate.

Fuelling - godknows. Has 2 extra injectors and is using a blitz ECU with a greddy sub-injector controller, past that your guess is as good as mine. Driveline is a lightened flywheel, twin plate clutch, and "custom gearbox" - this I'll have to investigate just cause I'm curious.

Has a lot of body bracing, adjustable shocks of some type, inside is normal black leather, has omori guages, and gizzmo launch control / anti lag. Was built up in japan, i think the gizzmo bits are the only thing added to it since it got here.

Anything more I unearth I'll let you know... Apparently made 400hp+ atw on around 20psi back when it was alive, so it could be one hell of a wild ride.

[Dell'Orto]

Any marks at all on the rods and pistons? Wonder if they just used 5SFE bits.

Will get some photos of it all tomorrow for ya

Bonita's engine eh?

Hmmm.... If the head has already had a port and polish, then I'd say that you wouldn't want to go smoothing it out anymore, so get a new head. Valves, cams etc can be used on the replacement head.

Agree. I re-used mine when it blew a chunk off one of the pistons, but it had only had one *small* skim before that.
A respectable engine re-conditioner will be able to help decide

Thats the worst of it - sorry bout the quality of the photo!

[Malcolm]

you might be able to get that welded + ground/planed, then get the head re-heat-treated, if the head is worth a lot. I would suggest calling some like kelfords to see what they think

[jener8r]

have a look around theres a few places that might be able to fix it, im in hamilton but im sure that could be fixed, my mate had an s13 and blew a hole the size of a 50c piece in one of the pistons, there were small gouges in the head similar to what you've got but his were a little bit bigger. im not sure how much it costs.. i suppose if you didnt want to waste the money getting it fixed and risking it may not work then get a new head. good luck

[Ako]

Yes... It was fixable! $60 later and I have one heavily ported, usable MR2 cylinder head still to be used.

Sweet

Now fix the 2.2 block you big girls blouse
