What do you think your 0-60/0-100 times be at 375bhp mate? Would love to know for sure at a guess would be better than not knowing at all.

Intresting project, i'v had a quick read put i'm going to read it in detail later or tomorrow.

This section must be my favourite of the whole forum list, really intersting.

0-60 maybe not that good, because of wheel spin.
hopefully something around 5 sec.
0-120mph maybe around 15sec.
60-120mph 10sec or under that is my goal.

I hope my weight saving gives me some potential to reach those goals.

we will see.

with 375-400 bhp you will piss under 10 secs 60-120
since fitting my new exhaust system, (I believe i now have around 320ish bhp) i timed 60-100 in 5.7 secs!! i'd imagine 120 would have come round in less than 8!!

i agree 0-60 is a problem!! i'm prob around 5 secs now i'd say, keeping wheel spin to a minimum!
I'm not the best a launching tho

to reach those goals don't think you'll need any weight saving to be honest!!
I'm prob 50kg over standard with all the amps and speakers i'm running in my car, and i pretty confident i could achieve all the above goals NOW!!

its amazing to think that only about 1.5 secs is slashed from the 0-60 comparing mine to standard 16vt.... yet a massive 6 seconds off the 60-100 time!!

I had 325hp / 1400kg alfa 155q4..
that was good for 6.3 sec 60-100mph
but 12 sec for 60-124mph

I have been making some new intecooler pipes to the mitsu turbo.
from turbo to intercooler, its gonna be the standard coupes silicone outlet pipe, then 2.5" 70 degree aluminium pipe ( 45cm long ) to 90 degree silicone pipe.

from intercooler to TB :
90 degree aluminium pipe (other leg is longer )
to the original metalpipe from fiat, and 45 degree silicone pipe to TB .

so total: only 3 pieces of 90degree elbows. and one 45 degree and 70 degree...should be good with the spooling also.

maybe, if everything goes right...

I can turn the key this weekend

after I get the car away from garage ;
-chip ( special version )
-making almost the hole exhaust
-cam job

Are you getting a live map or are you using one of the known chips?

I have Dinks normal chip and chip with extra fuel.
with standard cams, should be ok, but will test with
other cams too.( wideband test )
then I can go and make the chances with livemapping
( costs me 100e only )

its alive ...

okay..

I have now worked the other side of my car ( painted also )
and its time for exhaust ...

will give some photos later..

exhaust is done..

I only wait for yokohamas, and some wobblybolts..
then I can go and have my first drive this summer

should happen this week

what is the first thing, that will blow ?

first thing was :
after 3km driving there was a big hole on my boostpipe..
it was the hmm how I said it right...
engine running solenoid/ventil or something, that is next to the engine and battery..
it flyes away... have to make there some better system next.

now have been driving around 200km, and everything is ok..

boost is only 0.8bar, but goes prettty well..
100-140kmh is around 4 sec, looked at speedmeter..
fuelling : 11.9 l / 100km first test

Just been looking through your pics, the car looks amazing. I love the dash, how did you achieve the tan/beige lower section on the dash, looks great?

That turbo's a big one! Excuse my ignorance, but what is the big lump of kit above your manifold?

It's looking really good, keep the pictures coming.

Gareth

Ah, just looked again and the pic with the lump over the manifold is an Alfa engine!

Still, what is it!

Gareth

there is 50mm external wastegate over the manifold..



new car is with mitsu evo turbocharger, and with screamer pipe

just added new picture of my car..

I have had a little problem with my car..
I´m have been waiting one oilhose for 3weeks..
(silicone outside, good for oil use, and heat+ 90degree )
coming from England, ebay..
information said; over 10 available, delivery to Finland 4-6 days..
NOT...

I asked after 9 days, where the hell is my hose.. answer was :
in special orders, it takes around 4 weeks..
what hell, this was not special, if there is over 10 still available, and delivery is max 6 days..
well.. still I have to wait, because it takes same time if
I know start to order here in Finland..
..
hopefully, next week I can use my coupe again.

back for my turbo..

I have to say.. that mitsubishi turbo is the best, what I have ever used..
with G-tech RR on dynorun mode, it tells me, that best torque is with that 0.8bar 2800rpm -->
2000rpm is normal torque, then 2500rpm is already 100nm more!
I believe, that with this turbo, and 1.4bar boost, it should be very fast on track.. and very good everyday use..
if using standard cams, it should give you around 330-350hp, debend, have you done headwork.
then with other cams, you can have over 400hp, with still very good low down power/torque

I have done some measuring with G-tech pro RR and
I have about 275ps / 370nm 1.1bar with cat still there.
original cat...

and problem is, that boost starts to rise, so have to stop measuring around 5500rpm ..

so far, feels good.
just have to take a look at the wastegate, if its not opening enough ..

just to let everyone know, G-tech is pretty good measuring horses, when you do it right..

my ex alfa was 5hp difference, between RR and G-tech.

Hi jtm,

Have you been to RR?

hello.

not yet, there have been no space for my car on the carage
( have to make that cat replace pipe first.. )
after that the car is going to RR ..

I want there soon also..

added one video link on the project section.

80-120kmh 4th gear 0.8 - 0.9bar boost

spare cylinder head at home..

also NA cams, and turbo cams for spare..

20v model center console coming..

so winter project is : NA cams and stage 1 cylinder head.. should give me some more good power..

Sorry to hear you have a wrecked a head. Did you turn the engine over by hand first before trying to run it?

I bet none of the people who advised you about cams and pulleys have actually ever had those setups on their own cars! A painfully important lesson there; when reading advice on a forum, if it's not from first-hand experience it ain't worth squat!

BTW I use a Tipo 16V inlet cam and pulley no problem, so this will definitely work. Anyway, the 'proper' way to do it is with vernier pulleys and time it up on the dyno.

yes, glad I have the spear head at home..

I´m going use next time standard cams, but headwork done, larger injectors and goals for 340-350hp.

after that I save some money for C&B cams .
so no more problems ..

I use NA cams, turbo pulleys and standard turbo timing, like have been said, and done actually..
at least here in Finland..
but ;
I didnt know the history of my car, so it could be, that someone had already done headwork, etc, dont know the pistons what are inside, so
its my fault, because I didnt try to turn the engine, before I start ..

Ouch! Oh well, at least you know to next time!

yep, dont make that same mistake anymore..

it seems that only the intake valves have got some damage.

so the 228 / 8.6mm turbo intake cam on exhaust side is ok..

have to put some pictures after I got it away from the enginebay.

hopefully tomorrow I will get the head to the doctor ( the spear head )

Hmm

could someone tell me the number of the intake and exhaust pulleys, for Turbo engine ?

just to make sure..

is the 7691885 fiat coupe turbo intake pulley
