Or you could try fitting 6 x 45mm ones instead

throttle cable or Fly By Wire?
aiming for about 270bhp which seems to be middle of the road, but more importantly driveability as the car will be used for 'touring' and
the wife will drive it too.
60 or 65mm throttle body being the choice of ST200.220.
These are cable operated .
I have a TVR with the Jag engine and a Fly By Wire
70mm Throttle Body - mapped by Joolz.
There is a bit of 'hunting' at tickover, Joolz again saying low power throttle response it better with the cable operated TB's. Also
better with the smaller TBs
This engine will have to have Cats fitted as it is a 1993, so looking at Kraken 200 or even 100 cell units.

I have the opportunity to buy the Mondeo Fidanza flywheel for less than the cost of having my ST200 flywheel refaced, balanced and lightened, in fact
if I sold the ST200 one I would be pounds in pocket. BUT will I have a problem with the starter engaging the flywheel from the wrong side? Is it a
good or bad move?
Cheapest 65mm throttle body is this;
https://www.ebay.com/itm/98-04-GRAND-MARQUIS-Throttle-Body/301834522457?hash=item4646bd4f59%3Ag%3A4oIAAOSwSHZWfujf&LH_ItemCondition=4
The seller is not stating postage but when I enquired about one (different seller) they sent it with Ebay's Global Shipping Program. I have now
forgotten how much the total was but I have posted it somewhere on this forum. Standard Ford TPS plug as well

I believe there's two versions of Fidanza flywheel with differing back spacing and use different clutch cover and release bearing positions.
Just something to look into/check out.

Its the Fidanza flywheel for 2.5 Mondeos, since we know the standard 2.5 Mondeo flywheel works this one should too. The only thing in my mind is the
starter engaging from the wrong side but the ring gear sits on a shoulder which should prevent it moving, that assuming that it does.

5 speed RX8, I am sure that we all know that the internet quotes that fifth gear is 0.82 when we in Europe got 0.76

If you are using Johnathan's adapter plate then NO the jag starter motor will not match the ford flywheel ring gear. The jag has a bigger dia
and differant pitch.
Two options.
Modify the Ford flywheel to take the jag ring gear.
Or
Modify the starter motor and adapter very slightly.

I have already modified both Freddy’s adapter plate and the S type starter motor and they do fit. The question is all about the Fidanza flywheel which
is the correct one for Mondeo so the same dimensions as the ST24/200. I cannot remember which is the lighter one but that’s what I have. My build is
the standard one that most of you are following; 2002 S Type engine, Freddy’s adapter plate, RX8 5 speed gearbox, ST220 sump, ST200 inlet manifold,
ST220 lower inlet manifold, Crown Victoria 65mm throttle body, Mazda Tribute crank pulley and Rocketeer ECU and loom.
Back to the question, will I have a problem with the starter motor engaging the flywheel from the opposite side intended? I think not because the ring
gear sits on a shoulder and is retained by set screws.

I don't think you will have a problem if the flywheel has the same offset.
I don't think the pinion is going to hit the ring gear and try and push it of.

What do you guys have your rev limits set to (stock engine) ?
Mine is going back on the dyno at the end of the month for a map check after an engine swap and toying with lifting the limit a bit. Currently set at
7k and the power was still climbing.

Mine was 7100 rpm and still climbing,but Dale didn't want to go any higher on standard rods.
Also check your alternator ratio can handle more revs,I was knackering alternators with standard crank pulley so fitted a TTV under drive one now on
the new build.

From what i read, the standard rods are the limit as they stretch/go oval on the big ends, drop oil pressure then spin bearings. When i ran a standard
engine i set the limiter to 7000rpm.
Forged rods and ARP bolts opens the door somewhat

That makes a lot of sense, I have read many times about the spun bearing problems but it has always been attributed to low oil level/starvation. Easy
way for a manufacturer to avoid warranty claims.

I have a Fidanza flywheel on my 3SGE engine and the starter motor is the "wrong way round" similar to yours. All I did was to chamfer the
ring gear teeth on the opposite edges and I've had no problems with it at all.

If you have patience they do come up on ebay, last year I had to drive up to Stafford and looked on ebay to see what was about and without going five
miles off my route I had picked up a AJV6 engine, manual gearbox and a ST200 flywheel for a total of £295 and sold the gearbox and cats for exactly
£400! Engine and flywheel was free and £105 more than covered the fuel etc.
Any Mondeo/Cougar V6 flywheel will fit, the only difference is a few pounds in weight but they all weigh far less than the dual mass flywheel. I have
decided to go with the ST200 flywheel rather than the Fidanza, a few people who have had Fidanza's have pointed out to me that they are not
always perfectly balanced on arrival.

All the 2.5 V6 clutches seem to be the same,240mm drive plate.
I'm using a hybrid plate tgats paddle on one side and organic on the other,from Black Diamond.
It's the clutch they do for Noble owners.

I have another question! As this seems to be the thread for al things AJ30 and you guys have been so helpful, I thought I would add it here.
Between the banks of the older engine is an oil separator. Separating oil and fumes presumably? It is in the way of cleaning the middle of the V
(not essential, but it would be nice to tidy it up). Its also looking a bit tatty, so I want to check it hasn't rusted through etc. I
can't get it off in one piece without removing one of the heads, which I have no intention of doing.
The newer version of the engine doesn't have this, instead it has a blanking plate. So is it required? Have you guys left it in?
