there's a few companies which sell cams and state whetehr they suit gen2/gen3.

gen2 cam's are generally kept under 10mm lift. you could always go bigger lift and fit shimless buckets.

Is it worth going up to 10mm lift? I wonder if the stock ecu could keep up with it.

If I did end up going for shimless buckets, would you know of anywhere that may be able to sell these to me?

The one thing I wonder is how you would go about "adjusting" a shimless bucket, wouldn't the cam loads wear away eventually?

I saw a video of a 3sge head with a 2.2 stroker kit, individual throttle bodies and countless other mods and they only ended up getting 180hp at 6400. Which is only 134 kw at the fly, there was no mention of the cam duration or lift.

While the beams engine would work out much better in the long run, i want to see what can be done with the bits I have.

I am looking into lightening the stock rods, anything to help the motor rev easier.

I am hoping to go one step more and maybe consider a longer duration but drivability is still somewhat of a factor.

Aftermarket ecu for a gen 2 3sge are very difficult to source out, so for this option I am hoping to get away with a piggyback solution as much as possible.

aftermarket ecu is very easy to source.
adaptronic
motec
haltech
all make fantastic products.

you are going to need an aftermarket ecu anyway. to raise the rev limit.
If you are 100% serious about building the engine, talk to neale bates motorsport in canberra, or terry at road and track about them building you a high power 3S-GE.

i really wouldn't consider pouring money into a NA motor if your not goin to do the ECU.

to make more power NA wise you need to REV higher, stock ECU won't allow this.

i have no idea why that 5sge fitted ITB's only to rev to 6400. waste of time and money.

don't waste money on the stock rods, as DASIC said just get eagles. they're only $300US and weigh alot less and are balanced etc.

your not goin to have to worry about resetting the cam/shim clearances whilst you own the car (once you install new ones etc)or not for a considerable amount of K's anyway.

I misread the description of the youtube video:
It was 180RWHP at 6400rpm
Good returns but very low rev range.

I am somewhat worried about fitting aftermarket ecu's

I know nothing is cheap in this industry, but I do believe there can be some sacrifices made to find a fine balance.

I am somewhat worried on the reliability of aftermarket ecus, at the same time I think I am more worried about finding someone in Melbourne that would be willing to tune it.

I do have a 3SGTE spare from a 3sgte GT4 ST185 sitting here that I have been considering putting in and leaving this whole NA debate dead.

haha
I have been debating the thoughts

you will def need aftermarket ecu for quad throttles as they wont idle properly with stock ecu
saying that though someone got away with using a safc just cant remeber where i seen it
i would go for aftermarket ecu theres a few good tuners in Melbourne im sure you will find some

you willdef get more power from the turbo, but n/a is a whole different kettle of fish if i could afford another mr2 it will be n/a
some nice cams and quad throttles = screeeeaaaaaaaaaaaaammmmmmm
cheers

i know someone who can tune the emanage very well if you want to go down that way he is in Melbourne as well

average tune probably around $500(pfc) assume that emanage will be similar
no idea how much the emanage sells for nowdays have seem them for $400 before used maybe cheaper now.

should be good. the stock timing of the cam's will prob be suited to forced induction and you'll prob need to get some adjustable cam pulley's to fine tune and get the desired overlap for the best torque/power curve
