1zz help/advice

[paul.mcgrath]

Hi all , new member needing some advice /direction .....

I have a 2000 MRS turbo conversion with a "knocking" engine

Do I rebuild 1zz ? With standard of forged parts ....? Spoken MWR about a forged bottom end but with core charge and shipping it gets really expensive ....

Do I go for 2zz swap with my turbo kit , but this engine has its own oil issues and I could be back to square one again .....

Would much appreciate any feedback /advice all from members

Thanks Paul

Do you know what boost it is running and what the power output is?
Has it been using much oil?

This is my car on the website , pic of the dyno at the bottom of page , 177bhp

But I don't know what boost its running

[Carolyn]

Only a suggestion...

Drop the pan, pull a couple of bearing caps and see what you're dealing with.

Did the knocking start after some enthusiastic driving, maybe involving a long right handed bend?

This a duplicate thread

[paul.mcgrath]

Suggested I post here instead

I can't say exactly when or how this started , the car is driven quite hard , no track days for over a year ,

I'm no mechanic but diagnosis is engine "done" from where I had turbo fitted,

Tons of blue smoke when the car comes to rest after being off throttle/coasting say downhill

Revs die and car has stalled sometimes aswell , apart from that the car still performs well .....

[Anonymous]

I see maybe the mods could merge them for you.

As for the smoke she burning oil the question is that the turbo or the rings. You will have to take off some boost hose and check for oil.

[paul.mcgrath]

That's all a bit above my ability as they say ,

Suppose the question is anybody in and around the London area who'd rebuild the engine for me ...?

[Anonymous]

I would suggest headcase is the guy you should speak to.

[1979scotte]

London is a BIG place can we narrow it down a bit.

[paul.mcgrath]

Apologies.....

Enfield , north east London

[1979scotte]

The most trusted places closest to you are d1customs, rogue and headcase unfortunately theyre all a fair trot.
Loughborough or Rugby or Hastings.

[paul.mcgrath]

Yeh seems nothing in and around London at the moment ,

Spoken to a few

rogue , saying go for 2zz with my turbo setup adapted
Ebay 2zz conversion around 3kish with turbo adapted
Hurley racing , 1zz engine rebuild 1600 if "no hard"parts required
Another , rebuild my 1zz £1250 including stock parts

Who's in Hastings ?

[Anonymous]

Don't bother with the 2zz the turbo won't have enough puff to keep up in lift.

[Wabbitkilla]

From what you've said i would recommend a short engine from Toyota and new valve guide oil seals.
If you start going 2zz then you'd likely need to sort a 2zz anyway to get it fit for purpose and then there's the cost of adapting the turbo kit, engine mount adaptor, ecu, gearbox, and dyno time for mapping.

[1979scotte]

If you want a 2zz go for it but dont do it just because your 1zz has blown.
1zz is a perfectly reliable engine if well cared for especially with the revised pistons.

[paul.mcgrath]

Excuse my ignorance again , where can I get a new short block off the shelf and what

roughly is the cost ??

MWR works out costly with core and shipping !

[jvanzyl]

Have you considered seven motorsports? Not sure how far away they are.... But they seem to have Good rep... At least speaking to them for some advice might be an idea...

Toyota main dealers are your best bet. Some of them offer a discount for MR2ROC members, my local one in Chelmsford still does, at least. From memory, it's about £800, so using a dealer that offers club discount is worthwhile.

[Carolyn]

Hi Paul
Welcome to the club.  I'm sure you've figured out that the short block (while high quality) is not your cheapest option.  You'll still have to pay for the cylinder head work, the build-up of the complete engine plus gaskets, seals and sundries (like a new clutch while  the engine is out) and the removal and replacement.
The £1250 quote is probably your least expensive option, providing it's a warrantied job.
I do think that you need to ask whether a 2,000 MR S is worth the expense?

[paul.mcgrath]

Hi thanks for the welcome

Yeh it's worth it to surprise a few much much more expensive cars .....

Will rebuild the 1zz for the time being but will be looking for

a baffled sump and bigger injectors if any out there ....

[Carolyn]

Good for you Paul.  I respect your enthusiasm.

You might want to consider a simple baffle idea, while the engine is apart...

Let us know how it all goes?

[paul.mcgrath]

You obviously know your stuff that's a bit above my pay grade as they say ....

What would you do in my position re the car ....?

Was intending to spend 3ish on the 2zz swap with my turbo kit

What would you suggest if I wanted fast road and occasional track days ?

I'm no boy racer and north of 40 ....

Thanks

[Anonymous]

At 3k spend you only have rebuild in the budget.

A 2zz will cost 3k with rogue without the turbo added on.

To add the turbo to the 2zz will require a new turbo manifold yours is no good also the turbo you got will be to small when the 2zz goes into lift, so that a new turbo. Now added new bigger injectors and a map so making it another £3k on top.

Then after all that you will need to either upgrade your gearbox and clutch which is more money on top of everything else.

[jvanzyl]

Maybe go with the 2zz from rogue, and sell your existing turbo setup to fund a later forced induction option later?
