sorry bud, but you need to do some more research.

the 5sfe is the overbored version of the S block...so if you use 3sgte pistons you will have a 0.020" Gap ... that and the 5sfe head is different so the compression and squish will not be ideal...

Kerr1 i did the exact same thing that you are planning on doing except i had custom pistons made for my block. yes building your own motor is fun and not many people have built a stonger 5sfte but in all honesty a 3sgte swap is the way i would go now if i could. the horsepower to spending ratio sucks

thanks for chiming in. good to hear it from someone that has done it.
i couldnt agree more.
and thats coming from a guy who LOVES his 5sfte.
if your goals are ~250 or so whp, the 5sfte can do that in spades, with TONS of torque, if you build it right, and thats in stock longblock form.
once you start trying to modify the engine at all, the 3sgte is just a better choice, plain and simple.
as far as you doing the work yourself on the head, its not that easy...you dont just go in and start removing material, thinking its gonna work, cause it wont.

O i know that.....but my uncle has been doin this kinda stuff his entire life...he builds engines for a living....and he's 60...he knows wat hes doin and we r gonna do all the research....plus....i would actually b happy w/ 250whp b/c i would have some crazy torque lol...my car doesnt need a whole lot to keep up w/ most of the ppl around here....lol...theres a 210 whp 240 that smokes pretty much a lot of ppl around... and dont get me wrong i understand where yall r sayin just do the swap...but then to me its no fun...its bought already fast stock....i mean theres plenty of things i could just buy fast....i just want to b able to say i built the motor thats in my car from ground up. Thats all im sayin.

Then ditch the F head do the 5SGTE or stroked 3SGTE.
That's what I call fun.

yea...i guess that would b pretty kewl...i think i might do that its only like 30 more dollars for the 3s head.

My take on things...

Build the following :

5sfe head + oversized valves + cleaned up combustion chamber (slightly lower compression ratio) + cleaned up head ports , especially the exhaust side) ... your uncle can probably do this easy.

98+ camry metal head gasket + new head studs (even if OEM)

Stock bottom end

2jzgte cam gear machined to fit the 5sfe camshaft end

3sgte gen 1 exhaust manifold
Upgraded T04 based CT26 or equivalent turbo
3" Downpipe to a 3" exhaust

MAP-ECU2
RX7 440cc Injectors
No need for a 2bar map since the MAP ecu has a built in map sensor...

Clutch (with 280ft-lbs holding capacity), stock flywheel is fine

3sgte oil pan or tapped 5sfe oil pan

NO MBC (just get a turbo with a wastegate set around 10-12psi)
1 step colder iridium or copper plugs

EGT gauge
Wideband O2
Boost Gauge
Oil Pressure Gauge

Colder thermostat (170*)
Intake manifold gasket...

And that's it

go price that ... probably 5000 usd ... but that's how i'd build it... should make 250 crank @ 12psi ... with the ability to tune fuel, ignition timing, and cam timing and at least 25cfm of added head flow from the oversized valves (Even if you don't do any other head work with it)...

I guess what I'm trying to say... imho the most important part is tunability

so if you want to bring it down to the core... for me ... it's the cam gear + the map ecu2 + the colder plugs ...

around that if you want to save cash go with a 3sgte manifold, CT26 based upgraded turbo (but not a stock CT26 they are crap, at least get a CT20B), 3sgte dp ...etc

you can skip the gauges , but definately get it put on a dyno for tuning...
you can skip the MBC ... i don't think the 5sfte is a type of car you'd want to overboost, underboost...etc it just doesn't have the bottom end for you to want to switch between 10psi and 25psi ... so just set it at the right boost (the one you dyno tuned at) and forget it ...

that kind of stuff...

Tuning is key...

The oversized valves are worth 1.7psi
A ported throttle body is worth 1.0 psi
Cams are worth 2.0psi roughly

so having all those and being at 12psi is like a stock 5sfe running at 16.7psi ... see what i'm saying ...

yea...but im not spendin that much...lol....this is my plan...mayb 3sgte head....2 throttle bodies.....forged 8-1 wisco pistons...balanced crank.. ported intake and exhaust sides of the head....ported intake manifold...then turbo kit. if i dont get the 300 hp....thats fine...its still a trq beast.lol

Some portwork numbers to give you an idea... this is from an E55 mercedes head with stock cams...

Intake , 2 X 38mm valves
Peak flow 261 CFM
Average flow 201 CFM

Intake, 2 X 39mm valves + Race port
Peak flow 304 CFM (Increase of 16.4%)
Average flow 219 CFM (Increase of 8.9%)

Exhaust, 1 X 43mm valve
Peak flow 167 CFM
Average flow 123 CFM

Exhaust, 1 X 43.5mm valve + Race port
Peak flow 212 CFM (Increase of 26%)
Average flow 141 CFM (Increase of 14%)

To give you an idea, each 1.455 CFM is about 1 HP...

Most people don't see this kind of data for Toyotas so i thought i'd share...

sweet info....thanx a lot nuke.
