Not a Stroker, A proper 5sgte

What you do is take the 3sgte, Break it into two, Save the head (because its a yamaha head and flows extremely well), Throw the short block away (Or make it into a coffee table), go buy a camry motor (5sfe) Break that in two, Throw the head away, Throw the rods, Pistons, Oil pump, Water Pump, Etc away until your left with the block and the crank, Buy forged rods and pistons for 5sfe (or 3sgte and have crank machined to accept the 3s rods), Get a custom 5sgte head gasket from the states, Get some ARP head studs, Join the 3sgte head and built 5sfe block and Profit

 

Sounds easy when I put it like that

 

I could get a stroker Crank from spool for $1800 but that's quiet expensive and you still have to deal with the weaker 3s block. The 5s block is significantly stronger and has greater room for larger pistons. 

 

Should end up with around a 2.23 ish capacity and thinking about 11:1 or maybe even 12:1 comp because e85

High comp hybrid :spoton:

 

I know now what you're saying but numpties sometimes don't understand hybrids. 

That comp is going to be awesome. You'll start breaking the driveline next. 

I've been in my mates ear about going e85 on his corolla but he reckons he's nearly out of injector on 98. Pretty lame excuse of you ask me.

Sounds Nice doesn't it

Yeah Now begins the hard part of trying to locate parts.

I think im going to have to go custom pistons to get the comp I want

 

Weak excuse, Get more injector then win!

Yeah cbf spending he reckons. Weak lol! 

 

The scion guys in the states use the 5s don't they? 

 

Pretty sure that's the same block in the tarago/estima. If we ever have another kid I'll be getting one of them out of necessity and do what you're doing but N/A cause soft.

Yeah way off haha! It's a 2az. It's also in the Camry. That's where I got confused. 

That motor is big in the states. 

 

How much of this build are you going to do? 

Besides machining are you farming anything else out?
