6G Celicas Forums

Ok so my ride is ready, see profile .

SO the Block of the 3rd gen 3SGTE does fit the 3SGTE 2nd gen Head as I am going to get JG to do all the head work for me but I need a comfirmation as I dont have th ehead in my hands

I am estimating 600bhp for my next poject but I must be 100% sure that the oil ports water jackets all line up !!

Any help plz

I have a 2nd gen block w/ 3rd gen head, using an HKS 3rd gen head gasket. No problems. You would probably want to use the 2nd gen head gasket with a 2nd gen head.

The 2nd and 3rd gen blocks have identical water and oil ports, the only differences are in the heads.

The 2nd gen blocks are stronger then most 3rd gens. You'll find a few old posts in the UK and internationl forums from poeple who have cracked 3rd gen blocks over and over again. The wall thickness is said to be thinner w/ the 3rd gens.

On the other hand, 3rd gen heads flow better then 2nd gen's. A performance shop in Chicago flow tested both heads and a stock 3rd gen out flowed a 2nd gen w/ mild porting. Though with a full race port job, both heads would probably flow the same.

great info buddy thnaks alot for the pointers it was of great help

yeah i just wanna ask about the camshaft,
are they different size or the same size
i just wondering what differen't between both camshaft..cuz i just like to switch for more airflow

The GE camshafts have a slightly longer duration, so you'll gain a little power. Very minor compared to a set of aftermarket cams.

hi hi .

ive got a similar question but in reverse....

throwing ideas around for projects and am wondering if anyone can tell me...

a) if a 2nd gen 3sge head will fit a 2nd gen 3sgte block.

b) if it does what are the difference etc and will it make any major difference to the performance of the engine.

blonde out.

comments please

For the most part, the 3SGE head is the same as the 3SGTE head, with the GE cams being slightly higher duration. You can swap parts from the same generation heads without issues:
2nd gen 3SGE <==> 2nd gen 3SGTE
3rd gen 3SGE <==> 3rd gen 3SGTE

You'll get a slight boost from the GE cams, and I personally like the GE intake manifolds as they have a side-feed plenum, which matches my intercooler setup. Otherwise, there's no real difference.

cool cool and headset wise... one would assume i use the 3sge set.
i wouldnt have thought there would be much difference between the sets but the girl at th parts store says they are a different part number and 3sgte set obviously a lot dearer.
although if im running the 3sgte block it may be advisable to use the 3sgte headset aye as the head gasket will be thicker etc wont it

The head gaskets are different, the GTE has more water ports due to the additional heat from the turbo.

this is NOT correct, gen2 3S-GE block also have oil squirters!
i always use 2gen 3s-ge blocks in my builds because they are cheap and strong cores.

And to add to this, if you can, try to swap in a SET of intake cams from a 3rd gen 3sge. If you can get them on the cheap, it is a cheap ass cam upgrade on the fly, and it makes the motor sound very nice ^_^
