the dirty one is the gen 3, the clean one is a BEAMS piston

BTW this is a blacktop beams engine from the Altezza

not useful information

awesome, we have some good info coming in. I hope this becomes a good database of info for people

[BonzaiCelica]

Compression Test proof from JDM Online, Seems to be pretty good, 2nd cylinder was up at 200psi. other wise all others were at 195

http://cgi.ebay.com/ebaymotors/JDM-Toyota-...sQ5fAccessories

[BonzaiCelica]

Gear Ratios for JDM S54:

3.285 * 4.176 = 2027.5 - 37 mph
1.960 * 4.176 = 1209.7 - 62 mph
1.322 * 4.176 = 815.9 - 91 mph
1.028 * 4.176 = 634.5 - 118 mph
0.820 * 4.176 = 506.1 - 147 mph
Final Drive = 4.176

Compression pressure for 3sge Beams Redtop:

Reference level 1.37Mpa converted to psi is 198.7 max across all 4 cylinder for compression test
Limit 1.08Mpa converted to psi is 146.4

It says

Compatibility Info
Toyota Celica ST202 (10/93-09/99) Eng: 3S-GE

AND

The Fujitsubo Super EX Header is compatible with the following vehicles, please confirm before purchasing:

-ST202 Celica SS-II (5/93 ~ 6/96)

-ST202 Celica SS-III (5/93 ~ 6/96)

I wonder would RHD be able to confirm?

[njccmd2002]

they dont, i have seen a thread in MR2 that compares a beams bolt pattern with the 3rd gen 3sge and they mismatch...

[Rusty]

Nope they dont.

From what I've been reading up on the 3S-GE as listed in this thread, all 3S-GE blocks share the same height. this includes 3rd gen, 4th gen and 5th gen right!??

The same height? Thats not what you look at, if your looking at buying some extractors. its the bolt pattern/spacing of the exhaust ports which is the most important part, as njccmd2002 pointed out. As you would remember the 4th Gen 3S-GE BEAMS engines (redtop, blacktop) are a completely different cast to that of the 3rd Gen 3S-GE.

also I have another source to back this up. http://www.6gc.net/parts/382

sorry, but the info is not correct, it may have been added 10 years ago. also note: No one who owns this part has contributed their thoughts regarding this part yet.

just thought I'd add their website in here, for further info.
Fujitsubo's website: 3S-GE extrators

-ST202 Celica SS-II (5/93 ~ 6/96)

-ST202 Celica SS-III (5/93 ~ 6/96)

Those details that RHDJapan and Tony-B added speak for themselves. Does not fit the redtop.



can I ask what is wrong with the Factory extractors? Because your wanting to spend about US$850 for 1.1KW? The factory extractor type manifolds fitted the 3S-GE and BEAMS 3S-GE are very good. Toyota put some effort into the design and flow of these.

I think your better off putting your money towards your BEAMS engine.

[BonzaiCelica]

yes you make a good point Rusty and I know you are right. Well I want an all stainless steel exhaust system. A custom made stainless steel header will make it sounds nicer, perform a little better, and it looks much nicer in the engine bay. those are the 3 reasons why I want to make one.

[njccmd2002]

go custom.... build one from scratch..

[Tony-B]

I think Rusty has a point, maybe more gains to be had by free-ing up further down the exhaust system. I think i remember Edophus saying before about tidying up little burrs in the entrance to his manny, so maybe a little polishing?

I haven't been under my car in a bit but i think i remember a box after the cat.

Maybe minus those two could make a difference?

I wish i had a quality ECU tho.

rusty is right, there isnt a lot wrong with the stock extractors, the dimensions may be quite tight but they are fine for a near stock cam, the problem is and this is typical toyota the ingredients are right, the execution not so, the welds tend to be tack welds on the outside and welded on the inside, if you reweld the manifold so the welds are on the outside of the pipe, take a dremel and grind out the garbage on the inside of the pipe, so far i've found the manifolds to be really sloppy here, the design is fundementally fine, but the execution is poor. This isnt a power adder as such but will free up the engine at high revs, we found this on the beams and its also true of the newer 2zz engines where usually a ported stock manifold is better than the aftermarket ones.

To make it complicated It is worth leaving a step though at the bottom of the manifold floor where the manifold meets the head, you dont want it exact you want the pipe to be slightly bigger at the floor so there is a step down leaving the head, this helps to break up reversion pulses and does no harm to the exhaust flow.

OK I'll take all these facts and suggestions into consideration, it'll just come down to money in the end if I'm saving as much money as possible on the swap. Also on another note would you guys powder coat the header or leave it to dissipate heat into the engine bay on its on. from previous experience of not heat wrapping my ebay header the temp gauge meter runs at half way point when you let the car idle and once the fans turns on the needle drops back down to a little under the halfway point.

[Rusty]

I seriously doubt powder coating is able to withstand the heat from the extractors bonzai.

I'd suggest spraying them with vht(very high temperature) exhaust/header spray and then you can add some exhaust wrap (white or black) would look tidy, and should not fade etc. Should work quite well, in keeping the the engine bay temperatures down, and increase exhuast flow.

[TRDGT4]

or get them coated HPC

vht high temp paint dont work. it flaked on mine. that exhaust is hawt...

Over the past couple of months I have been searching for more information about the 3S-GE motors. I've found some info regarding the powerdeck spacer and making a custom intake manifold, ACIS plus turbo which I'm going to add later.

I came across on Celica-Club UK, a dyno graph which show the results 'before and after' of the powerdeck spacer, and has also come back into discussion over there recently, so I thought I might aswell post it up here swell.

"there was 5 months between dyno's

before
180 bhp @ 7300
135.7 lbft @ 4988
after
181.9 bhp @ 7139
135.8 lbft @ 4733"

[BonzaiCelica]

hmm wow 2 hp. that's like a air intake. So a total of 4 hp with a combined short ram intake.
