Funnily enough I'm not actually in the MG0C - coming up to my 7th year of MG ownership so maybe I should sign up.

Have the club ever written an article on Geraints build? His completely and utterly supersedes my ambitions!

There is also the MGCC (MG Car Club) who maybe be more cometition orientated so perhas a look at them might be worth while.

There wre gear boxes built to handle at least 200 BHP in every day use from the production line like those fitted to the 820 Vittese, 620Ti and the 220 Tomcat Coupe. The PG1 type box was also used by other makers so there must be something that will suit your needs out there. If money is no object the Quaife I understand make a 6 speed sequential box that will fit...................................... saddly I beleive they also cost about £7k

Mechanically, she is in brilliant nick so putting perishables and wear and tear aside, what parts do I need to uprate?

Here's my first stab...

1. Ductile liners (£395)
2. Forged pistons and rods (£800)
3. Uprated turbo -I've been told that the turbo from the Nissan 200SX fits straight onto the manifold - need to confirm. (£250)
4. Remap - fortunately MEMS3 can be taken to the desired power (and beyond apparently). (£400? - some variables to this)
5. Uprated fuel injectors - not sure which to go for (£150)
6. Gearbox - I believe the ZT's use a Getrag setup. Is anyone aware of a good uprated set up that other motors use? The standard set up might be ok if I don't stress it too much but if there's a good alternative I'd be keen to investigate. (£???)
7. FMIC with as few pipes as possible (£200)
8...
9...
10...

I'm glad the cranks good for 300bhp, keeps the bill down a tad.

I'll add parts to the list as they come in - might be a useful for others.
Looking forward to hearing from you.

Cheers

James

If it ever got on the road, a stock of replacement underpants might be useful!

Just curious but-----------with all this extra power how about the suspension, dampers, brakes etc ???

Or are all these mods just to make the car go fast in a straight line ??

Colvert, have a look at some of the recent threads.
This is a massive sore point for some and best left alone, imo.

Brakes were upgraded to the 190 set up and he was also looking into upgrading them again to the 260 set up

as for the rest I don't know

As I said---Just curious.

At my age ( 77 ) I don't get involved in sore points.

When manufacturers build high performance cars every bit of the car is designed to be able to use that power.

Without the strengthening of parts, power of the engine alone is just not enough !!

It's a bit like taking the horse out of a horse and cart and fitting in 500 bhp engine between the shafts.--------( In my opinion. Lol. )

Merry Xmas everybody.

Hey bud

Currently the cars on the 190 brakes as Jordan mentioned, plus braided Goodridge hoses and Brembo discs. I am looking into brake set ups on the cars with similar power.
Worth noting that the V8 doesn't have that different a set up.

Suspension wise, not really thinking of changing it. Coil overs might be a potential, not so much for the lows but for the rigidity.

Did you have any thoughts on what brakes/suspension to use?

Pistonbroke666 · 9th December 2014, 07:33

Thinking about suspension some more.

It'll still be a relatively lightweight K series up front and MG-R are known for having developed very high quality suspension set ups.

If the 75 V8, which I presume isn't on the hard springs can handle the power, why wouldn't my standard set up?

That's not a rhetorical question... any people in the know that know?

I'm at home recovering from hand surgery and seeing the delights of daytime tv....I've been watching ch221 turbo discovery (Chasing classics, Graveyard Carz, Wheeler Dealers etc)...a little bit green at the fact I'd love my 75 and my 924 to be given a bolt up full restoration...it's just the £££'s.

It's obvious that with enough money it's do-able!
It's a case of you making the car the best you want it to be.

I'm in Essex and when it happens I'd love to see it.

I've always wanted a street sleeper, seen a 75 v8 with the supercharger

I think my 924 is more realistic between the two...want to turbo charge it, need to find the right way and the right people!

Wish you all the best in making it happen
