Good cause he's buying a spare of mine...lol
lol at reading things properly (i already have my engine) £220 plus vat is a good price (any idea how they will affect the comp in the x16xe? will it be the same as the vxr engine, or is the head different on the vxr engine also?)Quote:

I would assume an F28 would fit easily enough as i think the F20 isn't an issue, iirc you use the flywheel and clutch for the box you wish to fit?
put of the f20 a little for having to sit at high rev's when cruising at a decent speed, this always used to anoy me with my xe. iirc darcy has fitted a f28 on a small block !
Cruising isn't something i plan on doing lol and the F28 is also heavier again and i would have to faf with the mount so an F20 should be fine for now, i can understand the F28 being more attractive for a road car though.
i need to find out the cc of both heads to see but i would take a wild guess say it would be about right, im after a trailer aswell lolQuote:

what gear box is on the vxr ??? im sure its 6 speed ???

The box "should" bolt straight up surely ? either way you would need a small block clutch with a F28 centre spline which is available from Helix but not off the shelf.
Personally though I totally agree that a F28 will upset the handling too much so I'd try and avoid it if you can.
My F18 took a years worth of abuse with a stock xe and dozens of bottles of gas, I sheared the teeth off it when going airborn and using the magic spray ! Atleast a F18/F20 is dirt cheap to replace and I can't see it causing any issues really with such low power.
Oh and LOL @ Browney moaning about cruising speed of the F20 lol
If you want to cruise at high speed buy something that does it well ! ie: not a nova lol
Yes mate it is, quite short gearing, I had one for a night and me and Gav gave it a thorough road test and were quite impressed with it !Quote:

i wonder if its small block or big block ???
Will be a small block box, have a look through Chris Astleys build as he did originally have one in his.
Sensible ??? that is possibly the funniest thing I have heard so far this year !

HA HA, surely a 1.8 Astra or a Vectra diesel is considered to be sensible, not a 200hp 1.6 16v Nova LOL
Boys and their toys.
owned (think thats twice now lol )Quote:

Does Darcy have a wip?Quote:

If they are small block they are still huge by the looks of themQuote:

I also doubt on a budget build that you'd be shelling out for a new cluster, so on the basis of a second hand one, IMO the ratios would be all wrong. Theyre also annoying and whiney for no particular gain on a 200bhp engine.
As far as what Id use, Id use the F18/F20 as jonboy suggests, goes straight in, costs 30-50 for a good one, ratios will work well, not too heavy....... Why complicate things!
The VXR had a 6 speed box but the mounts are all over the shop iirc and they wont be light!
can you not built an F20 with a long 5th? Maintain the current ratios to 120mph and then have fifth for cuising only.....
I completely agree with the sccr issues here. I said in the first place that i was going for the F20 for the reasons you have mentioned. I also stated i couldn't afford a sccr, especially a new one with the correct ratios so thats out of the question anyway, an F20 will be sound for the moment.Quote:

clutch wise you'd need the small block flywheel a small block c16 friction plate but with f20 splines... i would assume!
splines are different between the f20 and f28
why not fit an f23 from the astra gsi turbos? 5 speed lighter than the f28 but will cope with anything your 1600 will ever throw at it can be bought for 80-100
Because the F23 has strange mounts, the f20 is strong enough and the F23 shares splines with the F28Quote:

C20LET - 228 x 24 x 14 (shared with the astra 2.2 and 1.8 (F23))
No standard 200mm clutch with this centre is available to my knowledge
As I mentioned Helix do them, I've had one made before for a friend.
You can get anything at a cost, but personally for 200bhp and less torque than a let Id be using a 50 quid F20 box and a motorfactors clutch kit for 60 quid as opposed to 100 quids worth of F23 and a Helix organic plate.
Oh that's al most my spec^
If he uses a F20 he will have to have a clutch plate modified as their is no off the shelf item to fit a 16xe flywheel and F20 splines
If I understand Ali's post right he's saying that an astra 1.7TD clutch would fit?
Id certainly be prepared to try a 16xe cover with a TD pressure plate
So thats a 16xe friction plate and TD pressure plate? I'm guessing by your previous answer about torque that there shouldn't be any issues with slip using this set up?Quote:

Thats why i asked as alistairolsen said 'Id certainly be prepared to try a 16xe cover with a TD pressure plate'Quote:

My apologies "c16xe pressure plate (cover) and nova TD friction plate.
I see no reason to change the flywheel? afaik people do that when they want to run a 2.0 8v on an F13 or F15.....
Sorry my mistake, your right about the flywheel. Td friction plate is the same as any other small block fitment clutch and iirc the input shaft on a f20 doesn't suit any small block clutch so its a case of going custom.
Its been years since i had all thoe sort of parts kicking around though so i cant check but i am sure its not that straight forward although its not a major issue to sort
So we still arn't any clearer on this one which, is a pain as i was hoping there would be a cheaper and easier solution to this (like there ever is lol)
Some of the 1.7 na corsas diesels use small block gearboxes and the cav 1.7td use big block box so could i fit the fly and clutch from a cav td? Not sure if the bolt pattern on the 1.7isuzu engine is the same as the 1600 16v thought??
the z16ler/leh gasket turned up today and it fits the x16xe head bonus lol
thats a standard vxr turbo im going for lol
Thats a result dude and the standard vxr turbo is very tempting as it means less hassle - no manifold construction, a straight forward fit (ish) reasonably priced and off the shelf but that manifold looks really restirctive see here and i think they run out of puff at 220 bhp so i'm stuck here :confused: need to have a think about what to do.Quote:

I'm looking for similar power too. So we will see, like i said i will have to have a think and a price up on parts - i've been in contact with Borg Warner today to see what price i can get the vxr unit for through work, but vauxhall turbos tend to be cheap from the main dealer.Quote:
