any-one fitted a Jag S Type 3ltr engine and box?

[magpies]

I'm looking at fitting this set up into my TVR S along with Emerald K6 ecu so not needing the other electrical gubbins

The rear diffin the TVR will have to be changed back as previously fitted a 4.2 in place of the standard 3.6 (will retain the lsd)

I'm I correct in saying both the 5 and 6 speed manual boxes have a 0.75 top ratio?

I already run 17" wheels as smaller won't go over the larger brakes.

All info gratefully received

Reasonably sure it’s a V6. I thought the V8 was a 4.2 (or maybe 4.0).

sorry for the confusion - The original engine in my TVR was a 2.8 V6 Cologne, This had been removed and a 2.9 Cossy V6 fitted along with a MT75 box and a diff ratio change from 3.64 to a 4.2 - car expected to be used for sprints and hillclimbs although never was.

I'm now looking to fit the AJ30 to the TVR and not sure whether the MT75 box will mate to it so will want to fit the Jag S manual gearbox -
will both 5 and 6 speed fit the early engine and what are the ratios?

Think this may have been done before, sure I saw one in SD Autotec last time I was in there. Grey car.

Yes - I know about that one and going to see it in a couple of weeks

[magpies]

I've now purchased a Jag S type 3.0 litre manual car - drove the 175 miles home no problem

Still cannot find the gearbox ratios - will be talking to a gearbox specialist later, so don't know what diff ratio I will need

About to try and sell the V6 Cossy and MT75 box that is still in the TVR so then will HAVE to carry out the conversion.

Shame there is no LSD version of the S-Type diff

I did go and check out the TVR with this conversion and there are a number of mods which will need to be done to the chassis

and the likes of the anti-roll bar to be relocated.

.

What year model? Up to 2002 was Getrag 221 five speed. Easy enough to google for ratios.

Yes it is the Getrag 221 - The only info I get from Goooogle is from the Locost forum where it is stated

First Gear Ratio (:1) 3.25,
Second Gear Ratio (:1) 2.44,
Third Gear Ratio (:1) 1.55,
Fourth Gear Ratio (:1) 1.0,
Fifth Gear Ratio (:1) 0.75

BUT the chap with the TVR already converted says his has a direct 5th not 4th so has a 3.35 diff.

This is the info I need to confirm

I intend to go back to the more common 3.64 (I run a 4.27 at the mo) I also run on 17's with 225/45/17 tyres.

and car data have these ratios (direct top)
TRANSMISSION
1st gear:4,23:1
2nd gear:2,52:1
3rd gear:1,67:1
4th gear:1,22:1
5th gear:1,00:1

Sounds interesting. I have purchased a roadworthy manual SType with only 85k and driven it 200 miles drives nicely. Looking to use Emerald k6 ecu. Do you have any experience of different airbox as the existing looks very big. I'm going to modify the chassis and relocate the anti roll bar for clearance.

[magpies]

do you still have the mould for the plenum?

[magpies]

andygtt said:

Yes I still have the mould, made it in PrePreg.

Think its unlikely to fit under the bonnet of a TVR though, guess i could measure the entire height of the engine with the intake on it.

Id say the rocketeer one would be more suited as mines specifically made for a turbo application but theirs is for NA.

How tall is it from the flange at the top of the ITB's to the top face and the intake dia.

I'm thinking having flanges and small upstands made to fit the heads then short flex hoses to the plenum and 65mm TB at the mouth of the plenum?

andygtt said:

If I'm following what your suggesting you would end up with way too short runners and loose loads of power... plus my intake is designed for ITB's so I think it would be too big for a single throttle body I'm afraid.

If you have access to a Mill you could replicate my ITB's and carbon plenum relatively cheaply, however if you pay people to do the 'making' you will be looking at £5k.

yeah - I think the runners need to be about 250 to 300mm minimum from head flange to bell mouth inside the plenum. does that sound about right?

Sorry about my lack of knowledge, about the engine in question.

Is it the one Mads Lund used, in his M?

Best,

Yes it is ghe Jag AJ30 and their gearbox which has a direct top.

Slow M said:

How close to an original was your RS200 lookalike?

About as far away as possible. Basically a Toyota Celica GT 4. Front engine 4wd turbo 280bhp 1240kg.

Sounds fun.

My Jag engine TVR S1 is now on the road. Rolling roaded shows 265bhp.

Hi guys I’m just wondering how the AJ30 conversion performed?

Goes very well. Mine did 4500 miles this year. Grins all the way
