dude, just pile on some silicon gasket stuff, let it harden halfway then bolt it down, it will squish the excess out of the sides and the highest point should hold out a bit of vacuum

Gaz86 · 06-07-2008, 20:55

truly shocking workmanship, your work however A+

how come you helicoiled the flange why not just tap it? would have been cheaper.

if you take the box to an engine builder they should be able to skim that flat for you for about £20

Because I didn't explain myself properly to the guy that made the flange for me, and he drilled the holes to 6.5mm so we could put bolts through.

Sounds like normal practice tbh. My Mantzel isnt much better.

Them power boxes = something like the pikies outside my work would create out of stolen ally

Top stuff for making it work though

They do, but they get the gains

Obviously I don't know how they have been made, but if they were jigged a bit better and maybe some thicker material for the base then they could be so much easier to fit.

IMO something that works is something that is user friendly and is fit for purpose.

LongLiveTheNova · 07-07-2008, 17:02

Aye, thicker plate would help, as if you bolt them down to tight, it bends down the top plate, with it only being thin alloy.
Ive had no trouble with mine though, and my engine made 127bhp in this months TV RR feature

I agree to a point. I mean... he's gone to the trouble of including nuts, bolts, jubilee clips, bit of hose...etc, everything I'd need to fit it. So why not make sure the manifold fits properly?

Having said that, it's a lot cheaper than buying a Mantzel or branded powerbox. It's not the prettiest thing in the world, but it's a lot less restrictive than the standard inlet system.

LLTN, what have you done to your engine besides the inlet? I'm thinking the inlet and the flywheel might be enough for me for now, but I don't know any other cheap and easy ways of improving these engines without getting serious.

After the inlet is on properly, we can go over the engine and make sure everything's all there and cool, then we can crack on with fitting it. I can't wait to pull the old 1.2 out and get this new engine in and mounted up.

As soon as the big stuff is in and finished, I can crack on with the fiddly jobs like the wiring, gear linkage, throttle cable...etc. At the moment I feel like there's not really a lot I can do.

Hopefully Mr. Racer will be at Billing so I can collect my suspension off him.

And as soon as I get paid I'm getting the front brakes sorted and my sexy wheels on!

Mine came with some lengths of tube to support the inside of the manifold and stop it squashing.

Well, I say tube... some rough lengths of copper pipe....

LongLiveTheNova · 07-07-2008, 17:23

My engine had Mild kent cams(pretty much std lift/duration), de-cat, straight through exhaust, and the inlet box, and made 127bhp@ 6662rpm(the limiter), At Jamsport in March.
A Corsa Gsi with JUST a inlet box made 120bhp on the same RR.
Full writeup in this months tv.

Mine now has a 4-1 manifold and 2.25 SS system, but i now really need a higher rev limit, as it was peaking at the limiter even with the standard exhaust manifold/downpipe/

Jack · 07-07-2008, 17:32

Cool stuff! If mine makes 120bhp I'll be chuffed.

I think trying to get much more out of it is going to be too expensive. I'll run the 1.6 for a bit and see how I get on with it. Hopefully it'll be fast enough so that I don't get bored of it, but we'll see.

LongLiveTheNova · 07-07-2008, 17:38

Just strip the fook out the car

Plenty of fun on track

Jack · 07-07-2008, 17:40

I've still got all that black **** to get out, but I want to get the engine in and running and everything else sorted and get it actually on the road!

Can't wait to get driving it about. All the finishing touches can come afterwards!

Had a wage increase so I'm already dreaming about Monzas and Carltons!

**Lugy** · 07-07-2008, 17:42

What LongLiveTheNova said. Make it go round corners and stop brilliantly. Light/well balanced cars = much win.

djivesp · 07-07-2008, 20:39

Though stripping it you have to really think about. I wouldn't suggest it if you do any more miles than a quick drive to work every day tbh.

Its gonna be a little flyer

brace, new bushes and arb's front&back will make it a lot 'sharper' too

djivesp · 07-07-2008, 20:44

for a brace on the cheap check out my thread

Jack · 19-07-2008, 13:43

1.6 8v flywheel and clutch gubbins on the left, 1.6 16v on the right.

Dad wouldn't take my word for it that we could use my good pressure plate with the 8v stuff.

TB going on.

Ooooh, very nice.

Some blobs of sealant under the manifold.

That's about it for today. My shopping list for this week:

- A complete set of water hoses. Not sure what I've got or what I haven't got, so going to just buy a whole lot.
- Some new spark plugs
- Big oil breather from the rocker cover

We're getting to that stage where there really aren't a lot more jobs to do before we've got no excuse to get the engine in.

chrisscirocco · 19-07-2008, 14:21

Doesn>t look like that power box is gonna have any air leaks now!
looks a tidy fit

Gaz86 · 19-07-2008, 17:37

glad your dad told you about the pressure plate, youd have been sat in the car not being able to depress the clutch if you used the 16v one on the 8v fly

friction plates are interchangeable however.

LongLiveTheNova · 19-07-2008, 17:52

Aye, the friction ones are identical.
But the 16v pressure cover/plate is different to suit the POT fly....

I meant friction plate, actually.

The one I got with the 8v stuff is knackered, but I knew that when I bought it. The 16v one slips in a treat though.

Does anyone know how similar the water pipework is to the 1.2? Some of the hoses I'm missing or we've cut taking them off.

Fow16v · 20-07-2008, 08:09

i think you should be ok with most of the hoses you got on the 1.2, the way id go about it is stick it in and then see what ones you need and what you can make fit.

Jack · 20-07-2008, 08:20

Yeah, that might be what we end up doing. Although the current saying is "we might as well do this, because it will never be as easy as it is now with the engine on a stand."

My wallet dives for cover every time anyone says that!

Jack · 22-07-2008, 17:59

Jackpot.

Found in a box in my garage.
