Converting engine to VVTi


Jake

Recommended Posts

I'm not having any luck finding another VVTi lump for my car but I've seen a low mileage non-VVTi 2JZ-GTE engine and turbos for sale.

 

Apart from swapping the VVTi head, turbos , injectors, throttle body and loom onto the replacement engine is there anything else I would need to do?

 

Do both engines use the same spec head gasket?

How thick is a stock head gasket? 1.0mm? I'm going to get the VVTi head checked and skimmed if necessary but I'll need a thicker head gasket then.

 

 

Please let me know if there's a reason not to do it this way - before I waste a load more of my redundancy money on yet another engine :D

 

 

Thanks

The blocks are the same AFAIK...but 90% of what bolts to it is different...

So get your head checked....then go from there...

90%? I realise the intake side and exhaust side will need swapping over but what else? I think the anciliary items are the same (water pump, altenator, etc) but what about the sump and other things I may not have considered?

Unfortunately I have to make a decision today whether I'm going to buy this other (non-VVTi) engine or not.

 

 

Thanks

I'd get the block you're looking at...most of the different stuff as you've mentioned bolts to the head...and if you're using the VVTI head I can't see you having a problem - you'll then have a spare head you can get miching/fettled for the bronze one :sly: A plan or what! :)

 

 

Cough - okmaybenot90% - cough

 

There COULD be differences in the sump but I would have thought they wouldn't be in the way it bolts to the block - more like it's shape (if there is any difference)

Well I didn't get the other one :(

 

It was on eBay, as Pete was hinting at. The bidding was up to £691 with 1 minute to go. So left it till the last few seconds then bid £812 but the page took a few seconds to refresh and then said "Auction Has Ended"

So it went for £691 in the end, 46k miles, complete with auto box, turbos etc etc

:(

That would've been cheap to drop into that NA that went for 3250 the other day! 4k (plus a bit) for a TT.

Guest Terry S
Thanks guys. It looks this might work then.

I was hoping Terry might reply to this thread, Mig tells me Terry knows all about this vvti conversion business.

 

Sorry mate thought Mig asked you to PM me. Feel free.
