And as always with my car some bold or nut has to be drilled out.

Next week all will be fine, has been promised to me. As i have something else to drive and i am borowing an 1.9jtd 156sw i am also in no big hurry.

And tio be save i bought a secondhand turbo+manifold from somebody else as extra spares. (wich should arive next week.)

When things are ready i will let you guys know okay.

It is a pity that your manifold was cracked and blowing, this means that any results will now be inconclusive....

Shame, I was looking forward to the results.

Ouch....he's selling the last few at ?250 each...that hurts!

Inconclusive for Q4Jan's engine, but if it's significantly better this will still show. All of you Q4 owners have a pretty good seat-of-the-pants feel for lag, and if the manifold produces more HP this should be apparent aswell... Squadra quoted 235 Bhp for the Q4 with squadra chip, Q4jan's reached 230 bhp on the cracked standard manifold.. this could explain the 5 bhp difference...

It would be nice to know what other parts aren't standard now though, like air filter mods or exhaust mods, to form a better impression

**Evodelta** · 14-06-08, 22:09

Price now dropped to ?235.....

Probably they are all sold

I also wanted to push the "buy now" buttin

Greetings,

I am makeing my own. I will know the price when they are finished. Will be available whit flanges by desire. If somone will be interested ill make pictures and stuff

**Evodelta** · 15-06-08, 09:48

He's doing it to spite the dealer who has gone around him and sold out to another company as it was Paul that designed it, basically if he floods the market then less people will buy elsewhere. It still favours the dealer and the manufacturer though.

And you guys of course.

Please note, this is nothing to do with me, I'm just passing on the info.
Remember they are still untested and you still have to factor in the possibility of a fair bit of work if it needs changing (again). That said, at this price it is possibly worth a punt, I doubt you will ever get one this cheap!

To quote Paul:

" due to the fact I was undercut on the manifolds I was selling I decided to call it a day and just sell off the last 4 i had in stock for ?250 each, to my surprise they sold within a few hours and I also had quite a few e mails from people just missing out..

So I've thought about it and although my mark up will be considerably less it could still be worth importing another batch if I know they will be sold....

?235

Europe P&P ?60

UK P&P ?18

No Paypal.

I would be happier if this was all done with either cash or cheque because if people pay with paypal i'll have to pay fees...

Once I have 10 deposits of ?50 I'll place the order. Must be worth having even if only for a spare.

Send a cheque to;

Contact him Via his Ebay ad, anyone saved it? It's probably in this thread somewhere. Don't forget to ask for his post code.

Stuntz: At this price you are going to have to do something special if you are making your own.....
What this manifold lacks is:

Equal length pipes.

A proper merge collector.

Any provision for movement on expansion (which prevents cracking).

**wrinx** · 15-06-08, 10:50

The one aspect which put me off buying was the lack of road testing, or knowledge of the product.

If it cracks six months down the line I'd be a little annoyed

But as the price has tumbled....mmm!

**Stuntz** · 15-06-08, 11:19

Ill built one for me and test it if there willb e problems ill sort them out. I just mentioned it i have no interest in selling because i would earn very little but if somone needed it i would be glad to help.

**Q4Jan** · 18-06-08, 18:23

Today i heared the inlet camshaft also needs replacing. So comparing the to come measurement with the old one will be an even bigger no-no.

I hope the car will be ready by 26-6 as it is needed for a magazineshooting.

**Q4Jan** · 28-06-08, 03:56

The car was "ready" for the shoot. (Dutch car magazine GTO wich looks like a dutch "EVO". Is made once every two months so should be in the magazine before the end of the year.)

Shoot was with an E30 M3 cecotto and a 190 EVO II. And the place was Circuit Zandvoort. The story will be about the roadversions from the dtm cars of the 90's.

Problem was that we fixed some plumming with not really original pipes. So if boost goes above +.8 bar i get shaking acceleration and waring lights on the dash.

Would have loved to overtake those two cars on the straight but not fast enough this time.

(Q4 is also very understeered on racetrack, as i knew already, but not nice to be remembered.

)

I now will probable wait for the suspension(wich looks underway

) to arrive and have them take a good look at the whole car and fix everthing that was hasted this time.

Sorry for the delay, but as with Q4's sometime things take just a little bit longer.

**Q4Jan** · 16-07-08, 02:43

I would heave loved to show some nice rollingroad graphs....

But......

Today i tried to pick up the car from the workshop. (I guess for the 4th time....)

The D2 suspension was fittted. Back and front as close to original height as possible.
And i asked them to start with putting the stiffness on 5. (6 be-ing the softest.)
I drove a little bit with that around but moved the fronts to 4 later, as they are easy to change, the back is not easy to change.
I was positively impressed.
Much smoother ride than on the old yellow koni's. And seemed better in the corners. The car seems to roll less and drive smoother.
Although i did not drive much, as the engine is not running properly.

The Exhaust manifold is in place, the inlet camshaft was replaced.
And the oil-return pipe from the engine got a good replacement.

Still i get on/off acceleration when using throttle.
(Hick ups, bumping, nocking sensor cutting in.)

So i had them put the car on the examinator and it showed very lean when using the throttle.

So now they will check for fuel pressure and the injectors.

Hope to be driving soon....... But everything seems to brake down at once...

Tired of the 145 1.6 i have as a borrow-car at the moment.

(though the S2000 works wonders when i drive alone.

)

**Q4Jan** · 21-08-08, 14:39

Everything fitted and running okay.
Throttle response feels better and the car pulls more in the higher revs.

But comparing to the older run is not totaly fair.

I had:
- Crack in old outlet manifold
- Oxidated spark-cables
- One notch from a inlet camshaft had goten lower, so replaced it.

I did expect the car to have more torque in the lower revs, but i am very happy with the nice curve i got.

And a quick and dirty comparison between my two graphs.

I got the numbers from the graphs. So i could have made some small errors. (1-3 pk) But the general idea should be clear.

**Q4Jan** · 28-02-10, 15:43

After that last run i had the car on the rollers again:

But the graph was wobbly at higher revs.
Wich turned out to be two relais who were about to stop working.

Yesterday car ran great on (another set of) rolls :

252hp/ 399Nm

There were 2 147GTA's wich had 240hp and 242 hp.

I got a little les power on 5500 as expected, probably because the intercooler hadn't enough time to cool.

Second measurement is in steps of 500rpm, as it was not an acceleration setup, but one wich measures the braking needed to keep the rolls on a fixed speed.

So the ebay manifold sure don't hurt the numbers you get.

**jimnielsen** · 28-02-10, 19:42

Q4Jan - Those are pretty solid numbers. can you summarize the mods that you have made to you car? Thats 252 Hp at the wheels - right?

jim ~

**Q4Jan** · 28-02-10, 21:39

No Jim, i wish!

252hp at the crank.

Most rolling roads convert the wheel numbers to crank figures to make it comparable. Power to the wheels is un-usable between rolling roads.

mods:

- Squadra chip
- ebay manifold

- eps rvs exhaust, but *with* al three catalysts
- custom air intake with industrial filter
- well maintained car!
- Ron98 BP ultimate in the tank always

Other mods:

- D2 dampers/springs but with eibach springs in the back
- brembo big brake kit(front)
- strutbrace
- Team Dynamics pro race 1.2 17inch rims

Figures are modest compared to alfa standards as two 147GTA's got 240hp and 242 hp. Of wich one was tuned with carbon airintake+chiptuning. And they should have 250hp atleast.
