24v (or more Alan) rollcall
Discussion
Ok folks how many 24v conversions do we have and where are you up to in the process.? Also any comments re gearbox ecu etc.
I'll start
DamianS3 24v Jaguar Duratec, on the road (mostly). Jaguar getrag 221 gearbox (standard) MBE 9A9 ECU giving CoP, VVT and inlet length control. Requires. 3.15 or so diff conversion. Also running Granada cosworth spec brakes and LSD, Nitrons.
Great conversion, goes really and is quick. It's seen 240bhp on the dyno seems to get improved drivability and fuel economy too. Very loud through standard exhaust
Thanks

Does the chassis have to be modified to get the jaguar AJ30 engine and matching manual gearbox to fit?
Any modifications to the sump or inlet manifold?
Was looking at a BOA engine but going up in price and rarer than I'd have thought.
If the engine is from an S type they have a big protuberance at the front of the sump, you can either fit the sump from a st220 or X type or mod the lower cross member, which also involves relocating the anti roll bar. We modded the cross member as we didn't have a sump available and wanted to keep the engine as standard as possible. If you swap sump y may need the oil pickup to swap over too.Any modifications to the sump or inlet manifold?

Width wise you are fine as the engine is a 60 degree v design.
Looks like only 2 x 24v cars on the road and Pistonheads so far.. more are around. The biggest issue with the Jaguar engine is the ECU and throttle body. You could buy a cheaper ECU without inlet valve control and put the money to a set of ITBs from Jenvey which should see 280 or so BHP.. not cheep though.
Also don't forget you will probably want to swap the diff to a 3.15 or so item.
Thanks

We modded both front cross members, you can see just under the battery, sorry don't have a better picture right now you can also see the relocated anti roll bar.
We also removed the swirlpot and added blead lines to the radiator.
And a general engine bay picture
Jenvey 70mm TB this is probably a bit big maybe 65 mm would give better part throttle control.?
No ISCV the ECU takes care of idle on its own.

Morning..
Track v Road could do the mechanicals for you.. they have patterns for the conversion engine mounts,.. then You or Nobel etc would need to sort the ECU and wiring loom etc. Depending upon the inlet you go for.. as well as the options mentioned above a st220 inlet could be used with the St220 throttle body this would keep the inlet side simple from the ECU standpoint.
A lot of trial mad error on the first one (mine) but we know what works now., it's fair to say this quite a bit more work than the Cosworth route.
