Hi guys.
I am going to have my FJ20E turbocharged (and many other things)
I have a few question that I would like to ask you.
First: does someone have the valve timing graphics of the FJ20ET or at least give me the degrees for the phases
Do you know whether the clutch of the FJ20E and the Turbo version differ?
Some ideas on reinforced rear drive axles?
Ideas on remaking the rear suspension to fit s13 coilover kit (also to the front)
Also do you know a shop that can manufacture or is selling bearings (coated or any kind of aftermarket "street" or "sport") I mean the crankshaft bearings and those of the connecting rods
This is for now
I will post new question if I encounter something

Up the top of the page is a link to the Australian s12 website, someone ther will have the specs you need.

thanks man
I will check it out

Do LuckAug 19, 2008, 8:24 am · #4

Something very interesting to share. After the opening of the motor (as it blocked out a couple of months ago) we found out there is no wearing on the cylinders or pistons. They need just standart set of rings. One of the conrod bearings stuck and caused the blocking. Everything will be probably repaired as I am waiting for a response from Stewart Wilkins about the date when the parts are leaving for Bulgaria. In that matter I want to ask if someone has ordered something from this company? Do you know whether it is real or...something fake? It's because I transferred the money and for already two days they do not respond if they have received the sum or not.

Where are they located? Do they have a website?

That's it. I have read he was slow on e-mails but he has always replied on time. But for two days now there is no reply.
Do LuckAug 20, 2008, 1:22 am · #7

Okay. Everything seems to be fine. Parts left for Bulgaria today. Soon I will post pics of the rebuild. I can say FJ20 is hell of a tough engine...

JonAug 21, 2008, 2:25 pm · #8

Stewart Wilkins is a great guy - your parts will arrive. He does us all a great service by having an extensive amount of spares for these engines. I found it easier to deal with him by phone than email.

ArroAug 21, 2008, 5:51 pm · #9

Jon, where are you located? This guy here is in Bulgaria, I don't think he'll be calling them

Do LuckAug 21, 2008, 5:59 pm · #10

Thanks
I guess it is so.
Here are some pics of what is in the trunk since the engine is all dismantled.
Very interesting fact indeed - cylinders and pistons - 0mm wearing after many years of driving and I am sure that for the last couple of years when the car was in Bulgaria it was not spared...it was driven in high revs in cold engine...no oil check...spark plugs were very old and also here in Bulgaria no one else will ever try to rebuild such engine with view of the facts that someone has to send money to a stranger...and no one wants to deal with such stuff as rare finds.

Everything arrived and the motor is being rebuilt right now. Just some useful information: Probably when you would try to rebuild FJ20 you won't find any main bearings - even Stewart Wilkins does not have them. Instead he can offer you L18 main bearings. You need to check the oil feeding passages - when you put the bearing shells some of the holes will be half covered. Just elongate the holes to achieve full fitting. Then check the clearance. You may need to grind a little bit the bearings as they will appear to be too tight. Just get a cord tie the two shells of one bearing to form a circle then get a 600 or more wet or dry sandpaper and grind until you achieve clearance of about 0.1 - 0.15.

Guys I have a question. Will the FJ20ET clutch kit fit in the FJ20E??

Can't see why it wouldn't, unless the flywheels are different.
CandellanOct 4, 2008, 5:15 pm · #16

I know the CA20E & FJ20E clutch & pressure plates are interchangable as I had the CA20E button clutch on the FJ20E and back onto the CA20DET.

in short, no.

fj20e clutch plate is a 9" and fj20et is 9.5".

im running an rb20det clutch plate and pressure plate in my fj20et...
Do LuckOct 5, 2008, 1:29 pm · #19

Well thanks
Any ideas for kevlar or ceramic clutch?

CandellanOct 5, 2008, 6:13 pm · #20

Exedy made the 5 puck clutch ceramic clutch I'm using. It's the same as the S12 CA20E despite the different part number.

Some update: Before and after  It's actually after and before

A little update: Due to the "nice" natural-gas system the air intake exploded but with minimal damages. However I decided to get rid of it. I changed the entire air intake. This is the initial look (subject to some changes within a couple of weeks)
This is the overall look (sorry for the quality but it was in the night when I got ready
Engine

I replaced the old, veeeery old air filter with a new one (sport type) which soon will be situated differently and will probably have the cold air intake.

As I changed the entire air intake I needed to do something with the crankcase ventilation (as all catch-tanks in the shop were not available right now I decided to go for an engine breather)

Okay now give some ideas.
Everything is OK now but... there is a problem that I cannot figure out. When I drive it up to 3000 rpm without stepping on the pedal everything is OK but when I accelerate at full throttle until I reach for example 80-90 km/h the car suddenly stops accelerating as if someone cuts the fuel. The sound is as working with the 3 cylinders only. Then about 100 m after this the engine stops. Let's say in 10 minutes the engine starts again without any problems. This whole thing happened to me 3 or 4 times and not regularly. The engine is fully serviced and all filters (fuel, air oil) are changed, the injectors are cleaned in an ultrasound bath. The fuel pump makes let's say enough pressure for the proper working of the engine. It is not yet measured as I didn't have any time. The ignition is also OK. I am not sure for the spark plug though as they are not so good but there was no problem until now when the car was running on natural gas. Soo what could it be???? ECU? wiring problem? crap gasoline? dirty gas tank? obstructed fuel hose? etc??  give me some directions if someone had a similar problem

Do LuckDec 6, 2008, 5:21 pm · #25

Well after some checks I found out that there is fuel actually reaching the cylinders but however it is a lot and the engine cannot cope with burning so much of it. There is going to be either a decrease in the fuel or a check why the engine cannot combust everything (ignition regulator failure).

nice one  I will have this in mind  As I have checked with a S13 owner that at least the diff covers are the same so maybe it's a R200-differential.  Do you happen to know if an LSD for s13 with R200 diff will go in without major problems?

Well I now know that maybe the vane air flow meter is not working very well sometimes. I think I have reached the best air-fuel mixture by tuning the VAF's return spring. So now it is a little bit lacking fuel in the range of 6000-6500 rpm but it will soon be running a Megasquirt so the problem will be solved with totally new tuning procedure.
Do LuckJan 30, 2009, 10:34 am · #30

Problem solved!!! The car is running well now.
About 2 weeks ago I bought these:

Here is how they look on Mazda 626 GC - Like mine but this one is hatchback
