197 Gearbox in a 182 :S

[Torretto]

Hi I've been told by someone this is possible but I was under the impression that the bolt pattern etc was different??!

Can Anyone advise please??

 

[Chip-mk1]

Possible, but certainly not easy, you would need to redrill the engine where the gearbox mounts to it, make custom mounts, and make custom shafts, and even then I would expect clearance issues.

 

[The Chubby Pirate]

Why would you want a less reliable gearbox than you have already??

​6 gears isn't it?

This, I would love a 6th cog!

 

[Chip-mk1]

Cant see its worth the huge amount of hassle just to get 6 gears on a 172 TBH

 

[Lal B3N]

Is a 6th cog really needed in a 1*2? The only time you would ever need is the motorway and they will already do 40+mpg at motorway speeds?

 

[Addicted]

You may get a 6th cog, but it'll break 6x quicker too!

 

[jon_r]

And be doing 6x more revs because of the stupid ratios.

If you do a lot of motorway work and have a ph2 then just fit a ph1 box, its a few hundred RPM less at cruising speed.

Feel like nicer ratios for on trackdays though tbh on the 197/200 boxes. Thats the one potential plus side.

 

[Martin_172]

less reliable box? lol behave theres nothing wrong with it, its a massive upgrade over a JC5 in feel alone!.
of course abuse it and it will die just as quick as your JC5 would!

where the box is nicer, the ratios and 6 speed were really only to offset the weight of the 197/200 I bet a 172 in 5th and a 200 in 6th are around the same rpm at 70mph!

Ok Cheers Chip ) , has anyone done this already do we know??

 

[Chip-mk1]

Fred has put a megane turbo engine and box in, which is essentially the same job, other than you also need to redrill your block (or use a 197 engine which is what I would do as its a better unit anyway)

 

[jon_r]

I bet a 172 in 5th and a 200 in 6th are around the same rpm at 70mph!

I have both on my driveway. 6th in a 197 at 70 is doing more revs than the 172.

The 197 box is much nicer to use though, i'll give you that!

Is yours a Ph1 box still?

If so its a few hundred RPM less at 70 than the Ph2 box is.

Ph2 box is more similar to the 197 IIRC

Was this Fred @BTM??

Hi!

 

[mi16chris]

On a good day lol

 

[Sam@NP]

Does the 197 reach its top rated speed in 5th or 6th?

 

[Torretto]

Hi!

Hey Dude, Besides the obvious fouling and custom shafts etc is this relativly straightforward?? dropping the F4R-T in??

 

[jon_r]

I don't see why it wouldn't in 6th tbh, it's so bloody short.

Edit - reply to Sam.

 

[Fred@BTM]

yeah it sort of bolts straight in, its the £700 custom driveshafts, and about £1500 of custom fabrication that is a pain (plus electronics)

So your talking 3k + the engine and box arn't you then? :/

 

[Fred@BTM]

unless we bring out a conversion kit................

 

[fil_b]

is that likely?

 

[Torretto]

Really??

 

[skiptontweed]

Hate to be devils advocate, but why not use a 197/200 engine bolted to a 172/182 gearbox?
The 1*2 is lighter, so you probably dont need 6 ratios (I use 3 gears at oulton in a 200, 2 gears in a 172)

Have I missed the point?

you want to use as many gears as possible on track. Shorter the ratios the better providing you're not bouncy off the limiter on the longest straight.

197 box has shorter ratios so I can see the attraction.

 

[theduck]

6th is same as 5th on a 1*2 though.

 

[Sam@NP]

6th is same as 5th on a 1*2 though.

True story? Even on 15s?

 

[theduck]

Iirc, 6th was 3500rpm at 70mph in the 197. 172 is 3000rpm at 70mph in 5th

 

[adamlstr]

The 172 is more or less Revs*2, 3.5K = 70, 4K = 80 iirc etc etc.

 

[theduck]

Ph1 isn't.

 

[adamlstr]

Ph1 isn't.

Touché.

 

[stephen chadwick]

if you want a 6 speed buy a vag. waste of time the ratios are naff

 

[Sam@NP]

​well that's sorted.

Sorry that Q got a bit hijacked then..Fred is this in the pipeline??

 

[Martin_172]

Does the 197 reach its top rated speed in 5th or 6th?

from memory my 200 would do 120 in 5th then 150 in 6th

 

[jon_r]

Just tried it in the 197. 6th @ 70mph is 3600rpm and 80 is 4100 rpm.
