Hi all,

I want to show you my (and my fathers) yellow Coupe and tell you some story....some of you knows the car, as it is quite fast 16V atmo smile


Its a 1995 (exact date of production 23.2.1995) 2.0 16v NA in base trim which serves to first owner as "company car".(He was wery keen in sport/vintage cars, as he also had some Jaguar V12, Tatra 613, Porshe 928, Lotus 7)
During the first five years of its life it managed to cover over 160000km and experienced one small crash on driver doors.


Then in 2001 we purchased it, as there were only 3 used coupes for sale at the time (and this one was the oldest and cheapest).

However it has full service history and all keys and Cards, so there was no reason to not buy it.

First year we did ordinary service and some cleaning of engine bay and engine itself to see how much work waits for us:).

In 2002 we decided to improve audio- 2 set of Phase Linear PC 165.20 speakers and some JVC Head unid with CD changer was installed.
During the 2002 summer we disassembled front end and perform some de-rust and new paint of the front beams and some serious clean/paint of engine.

Coupe also experienced first defects:
1) worn alternator brushes so, it get new brushes and bearing+ some recondition of winding
2) worn VAE valve causing "swing" idle or steady 3000rpm at idle... changed for new one ane defect disappeard.. Later I found worn piston in defectiv VAE valce, which didnt seal properly.

2003
- first fatal failure of engine... snapped timing belt (luckily on idle) causing damage to all 8 exhaust valves.

click to enlarge

So engine head was repairedd with new valves , sealing ETC...
during the year we visited some tuning-meetings and also tried V-MAX on ~1.5km track on unused airport... 187 and 191km/h was good for stock 140bhp car, as there were already some Civics Type-R which clocked around 205km/h.
At the end of year I moved to the back and did the same de-rust and new paint to wheel arches and panel under rear bumper.
As bonus, black lover part of bumpers and side skirt was painted to body color... smile

2004
I polished the valve cover and found "tuning tip" for drilled Airbox.
I drilled the airbox with 6x32mm holes and modified it to look as 16VT one... remaining parts above radiator were removed from the car.

Sound of the car was great and it feels fasterresponding...
However, something wrong early happend....:(
During one drive, oil temp suddenly rised to above 130°C and oil pressure dropped almost to zero.
This meant engine out and perform some work...

It was found that instead of one, all bearings were somehow OK (it would probably work with new oil..),
but oil pump was KO (scratched), so new one was purchased, crank grinded, new bearings and new exhaust cam (one lobe was badly damaged..) fitted.
Engine got some serious clean and blue paint, some mods were performed also on exhaust (decat, mid silencer out) to improve sound and performance - as we found there was already ANSA SPORT rear silencer fitted by previous owner.

2005
first 1/4 race and time 15,84s - not bad for stock car with low-cost modifications...
here sprinting with Civic 1.8 VTI:

At the end of this year we decided to perform some serious modifications to engine.... so engine out.


2006
during first month of this year engine gets most of its spec. it has up today.

- Ported head
- round valve seats and valves
click to enlarge

- reprofiled cams (294IN/285EX 10,3mm lift both)
- raised compression to 11,3:1 by block lowering
- balanced bottom end
- removed balance shafts

click to enlarge

- raised fuel pressure to 3.6 bar
- removed Throtle body heating
- "custom" made Chip with rev. limiter set at 7800rpm...
made by some czech company with good advertisement (if only their work would be so good as their advertisement- but its typical image of chiptunig companies not only those days, but also today..)

With this specification it was capable to "fly" through 1/4mile track in 14,8 +/- 0,2s and at ~148-149km/h on stock tyres depending on conditions.

2006 gallery (engine build)

2007

"New" suspension was purchased - in fact it was used one- front FK automotive with adjustable height and rear Eibach spring and Koni Shock absorbers...

2008

I saw, some picture of black Delta integrale with interesting intake manifold...
After studying pictures of lancia engine I foud, that its Kappa 16VT intake manifol, so I purchased one, did small porting jod to match the channels and fitted it to car...
I have to say that remove stock intake with head on engine is pain smile

As I expected, the behaviour of engine changed, and engine breathes more freely above 5000rpm..

2008 gallery

2009
After studying some literature and easuring current one it was decided to create new exhaust..

-Header primaries remained stock (only polished from outside for better look),
-secondaries were enlarged from 42mm to 50mm, and lenghtened to 30cm with better connection (stock header has in 2-1 connection bad pipe crush, which reduce pipe diameter to something under 30mm..)
-rest of the exhaust performed in 60mm piping with 2 straight trough silencers

- engine behaviour dramatically improved... better idle quality and low-down torque...

I also bought new slicks and 16VT wheels - the difference between slicks and road tires is incredible.

1/4 mile time with road tires before instalation of new exhaust was:
~14.9s, 148km/h

1/4 mile time with road tires after instalation of new exhaust was:
~14.9s, 153km/h - increase of trap speed simply indicates increased power ...

1/4 mile time with slicks after instalation of new exhaust was:
14.4s, 154km/h , first 1/4 ride with slicks with no experience with starting at slicks

1km time is now 26.3s..wich is the same as 20VT coupe in good condition...

That year I also experimented with larger- 60mm throttle body:

I made it from standart spare one.
As many 4 cyl. engines with ~160 BHP has 60mm throttle - for example PUG MI16, Honda 1.6 VTI, Citroen Xsara 2.0VTS, Clio sport, so I decide, that the 60mm TB will be OK, for good flow and throttle response)
The butterfly was made on CNC laser cut (according to my CAD model) from stainless steel. Throttle body was milled out on CNC machine - before milling I should weld small amount of material to the bottom part, where isn´t enough material for milling.

click to enlarge

Next I modified the throttle shaft - by reducing the thicknes of the shat by 4 mm I get next ~10% increase of throttle area. Total area increase of the area is equal to ~ 30%.
When I fitted it on the car, I noticed, that it will need some fine tuning of fuel/ingnition...
The engine miss something, but is still powerful but with poorer throttle response caused by inadeqate (lean) accel. enrichment...

2009 photogallery

2010

Fitted Walbro 255lph Fuel Pump
- started to thinking about more engine safet with wider belt, so purchased some JTD cranck with wide pulley..

- Purchased Wide belt kit, STeel-lightened FW and balance shaft elimination kit from deltaparts...

click to enlarge

- purchased OMP paddle clutch with pressure plate..
- purchased 4,07:1 final drive from AR 1.6 TS

_ all parts lie in the stock looong time....


2010 photogallery

2011-2012.. car did not move from its place due to lack of time...


2013

I decided to improve oil cooling, so I purchased and installed 16VT engine mount and oil cooler.

During the fitment of Oil cooler and engine mount I managed to fit also Wide belt and pulleys...
I found one quite bad thing about crank pulle delivered in this kit - the nose was to wide and it caused that the pulley did not fit to the crand properly, causing sever wobble of pulley assembly ...

So some small machining was needed and now everything is now OK.

2014

I managed only one ride to meeting of classic italian car and remaining time of the year it stand in garage...

At the end of year I purchased FC-Performance chip for my Tipo (which will have Coupe ECU, because of 16v engine conversion from 8V..) and some Piggy-back for Stilo...

click to enlarge

next photo from meeting:

FCC_meeting

2015

decided to try something:)

I put FC-performance chip in and was wery surprised of behaviour of car - low down and mid rpm behaviour was fantastic (better than before!), but above 5000rpm the AF ratio become hell lean...
The engine was unable to hold steady idle .. so I tried to play with Piggy-back to get AFR nearer where it should be... not much success but found the way, how to tune and what properly via "Live-MAP" to get desired engine behavior.
ALso installed 60mm Throtle body I did few years ago. As bonus I tried "road dyno" and it showed some 160hp/6600rpm at wheels with tendency to increase in higher rpm, but AF ratio was 13,7:1 so I stopped to measure at around 6700rpm.

I Also Purchased Oil separator from 16VT and 20VT wheels which I refubrished and fitted with new Federal RS595 tyres.


2016

When I concluded, that "remote" mapping with Flea will be somehow painfull (especially on idle anw low down territory) I got in touch with enthusiast (forum member Phob) who can do live map and did first mapping session to get stable idle and AFR in spot for "MOT"(emmision) test as testing methods changed.
I also purchased and Installed 200CPSI high flow cat and sucessfully passed czech equivalent of "MOT".
I was also succesfull with legalising 20VT wheels so it was good year:)

But at the end of summer we continued with mapping... but big problem ocured.. as the engine reaches max. Torque rpm at WOT it got strong misfires..
I tried to change/chceck everything - spark plugs (from Bosch FR5DP, oridinary Champions, NGK from big HP number cosworth engine, NGK BPR8ES), fitted new leads, rotor and distribur cap, tried to change rpm sensor, coil.. with no succes...
Only thing we know- the AF ratio become lean by ~1 degree and it is nod dependent on advance and injector opening time...

2017

At the beginning of the year I studied problem of misfiring and found, that the cat seems to be restrictive - that size (200CPSI, 100mm body diameter) is suitable for about 150BHP..nothing were changed on the car instead of cat..
Then I thinked about improving braking...
As employee (Brake booster designer and FEM specialist) of Continetal Automotive plant where we also produce vacuum pumps I started to search for suitable vacuum pump (because my engine has wery low vacuum level - around 0,1-0,2 bar, instead of 0,6bar - all due to cams and common plenum)
I chose pump from Volvo Xc90 from "our" competitor - Hella.. this pump is smaller, and quieter:)

After Install of pump I found serious failure - due to corrosion cracked front brake line, so car was jacked and I fitted new all brake pipes and hoses.
As the car was on the jack, I removed gearbox and fitted (finally smile )

the steel Flywheel with paddle OMP cluth with 228mm diameter and Lancia dedra turbo pressure plate.

When I decide to revork exhaust and remove cat (not forever, I vant to fit 100CPSI, with biggest body I can Fit..) , I also Purchased new mid-silencer from Powersprint - as big as can be fitted under the car - round HF45 (I don´t want to have so loud car as time has changed and it became cop-atractive..)
click to enlarge

I found, that previous mid-silencer was somehow restrictive.. from 60mm bore suddenly became something around 35mm..)
click to enlarge

I also perform some de-rust of floor...
click to enlarge


AT the end, I went out of the garage and chcecked if everything is OK... and WAS smile

no engine sputter and misfire, on every gear engine could rev freely over 7000rpm (even over 8000rpm on tacho, rev limiter is slightly above 7800rpm )


sorry for some bad photo smile they were taken from old mobile phone and/or scanned...

this is some summarization of almost 16 years with coupe, I hope that you enjoyed the story and some updates will come evil (I also hope, that links to photos will work)

yesterday I did small upgrade to exhaust system

click to enlarge

127mm diameter, 100CPSI CAT for low amount of backpressure, but high level of "polluting gases"conversion .. euro2-3 capable

click to enlarge

wery easy to work under the car with such stiff body.. lifted only on one point

click to enlarge

exhaust assembly

click to enlarge

finally washed

and today I did short, but fast test drive if everything is OK

Hi all..

I spent one the best year with my coupe smile

did over 1000km, burned lot of fuel and made the smile on my face every time I drive it hard smile

I did only ordinary maintenance, and slight engine tuning - further retimed cams, and set the WOT A/F ratio little bit leaner (12,8-13,2:1), as it was on safe site (11,8-12,2:1..) .. engine now runs much happier smile

here are some autumn shoots ¨from last ride this year...

this year is quite good... did already over 1000km and its not end of season:

... however some minor issues occured...


1) torn mid engine mount and upper one on the side of timing belt... so I´m searching for suitable replacement, if possible uprated...

engine moves more, than I accept and contact with some body parts I don´t like...

click to enlarge


2) old, hard O-ring in oil cap... this causes, thatoil cap gets loose and oil sprays from the engine everywhere... so this is good to be checked and possibly replaced by new O-ring by every 16V/VT ovner...


by the time I asked few local companise if its possible to make exact copy of exhaust header, but from bigger piping... - I already have primary branches stock (38mm OD), but enlarged secondaries to 50mm OD and outled to 60mmm.. I want to make primaries from 45mm OD piping to free more HP from the engine.. smile
