3sge 3rd gen inquiries Options

[millow]

Helo guys im new to this site, im from the philippines and just got a 3sge 3rd gen for my st 171, was planing of upgrading the engine while its still out of the car, was thingking of puting itbs from a black top 4age and changing the values and springs from a beams which are allitle bit bigger or from a gte im still sourcing for the specs of other ge or gte and if they can be swap with minor machining, then go adjustable cam gears and cams with better lift, its kinda hard and expensive to look for 3sge parts here so im looking at the options from other gen that can be an upgrade for the 3rd gen, any sudgestions will be most appriciated. Thanks

thanks guys, so stock springs are ok, just dont beyond 11.3 lift, i will try to find a good machine shop that can do the regrinds, thingking just 272deg with 10.5mm lift, how about cam gears, is it useless to use bigger values

i looking if i can mill the TB will not go itbs for now, what is a good piggyback system that a can use?

my 3sge cam from a JDM automatic, is it true that the intake cam of an 3sge 3rd gen auto is 240deg 8.7mm lift than the manual 252deg with a 9.8 or like what you said 10.115mm, havent opened it yet, i got the engine with out tranny

about regrinds

- new-cam-profile must be prepared by professional engine engineer , designed and calculated for specific engine
(my friend who did it for me have 30 years experiences in preparing racing engines ,
he designed cams and head for soda FABIA S2000 , 2L NA ,results 295hp 260Nm )

- even some one will prepare cam-profile Im sure You will not get 272deg from 240 automatic stock cams
- find good machine shop for this task ... hmm try it .... will be very expensive

GOOD LUCK .. ( I did it .... )

BUT

I can sell You only cams 500USD set ,

IN 278deg 11.2mm , EX 276 10.5mm + shims

-but shims must be grid to correct valve-lash for new cams on your-head
-I recommend lower-head for change CR from 10.5 to 11.8

For 1000USD You can get , set including head work done (CR , valves-lash , valves-set )
You need only put it on block ...
