3SGTE or 5SGTE?

Hey all, I'm just after some opinions about what engine I should build up...
 
Basically I want something around 270kw atw that I can build and not have to reopen ever, even if there's a fire!
 
But I still want a fair bit of drive-ability. Which is why I'm leaning towards a 5S...
 
And, go!

Of course the 5S always wins in terms of end result, but the devils in the details. 5SGTE can be treated legally like an engine conversion, so there's concerns from that perspective. Building one isn't straight forward either, you really need someone you trust.

Its not just the crank its the block that needs work as well. Holes for the alt, drive shaft brackets ect.
I cant remember the exact cost of doing mine but if you allowed $1000 extra on top of building a 3s you will still have change.

do it yourself, it's not rocket science.
 
place old gasket on block to see where the holes need to be drilled and the size.
 
or you can buy the ATS 5sgte HG, tho i'm not sure if they're to suit gen2/3 heads or both?
 
most of the holes are there for the ALT bracket, as they have the PS pump bracket there. TBH the alt bracket is way overkill with the amount of bolts it has etc.
 
also the camry has a driveshaft support bracket there also, so i don't think you need to drill holes for that.
 
if you want to run the STD turbo then you also need to plan out where your going to source the oil feed for the turbo from.

I had to drill for alt and drive shaft, but if your contemplating building it yourself you should be able to manage this.  My 5s block had an oil feed so was a non issue.
 
Machine work (coolant flow related too) is where most of the differences are so get this done by someone in the know, other than that mine was built just like any other eng.
 
In terms of performance, I run a GT2860rs so not much larger than standard, but I noticed a huge jump in response and off boost power.  Spool time is awesome.  This is all on my 'run in tune' so I would expect much more from a power tune.
 
What turbo are you thinking of running?
 
Oh shameless plug, if serious about going a 5s have a look at Totens proposed built eng in the for sale section, it would save you all the hassles involved and you wouldn't have any reason to open it up no matter what future upgrade you may desire.

Any particular reason why most people go for 98+ blocks?
 
I've heard that GTX3076's feed a 5SGTE pretty well. Will have to do quite a bit more research into this though.

Yes. Gen4 I presume you mean off a caldina. Doesnt have provision for a dizzy. Has a crank angle sensor and camshaft to suit.

98 5S block (in US terms) supposedly had more meat/reinforcement around the water pump. Although I've yet to hear of any cracked 5S blocks.
