Tuning how to get more power out of a hgt engine

I think you can fit Alfa TS cams (1.8 or 2.0).

I am sure someone will be able to confirm this.

I know a fair bit about the Alfa TS engine, and that it is similar to the 1.8 Fiat engine, but I am not 100% sure if the swap will work.

If it does you should get around 10bhp, but you will need the Alfa cam locks to set the timing.
 
Hi,think this has come up a few times tbh..
Im after extra power for mine..
Im lead to believe 20vt injectors will work..But the fuelling will be out so if you were to get it chipped and have a good Live map on it,you should be ok :)
Also heard that the inlet and maf will fit and work,but dont quote me on this..Head work will go down a treat with all these mods tho (y)

Injectors should only be upgraded when you run out of capacity, which is quite some way to go on the 147bhp engine.

The Twin Spark cams aren't better.

Air intake revision, exhaust and re-map are the cheapest ways to get more power.

All really depends what your budget is.
 
siniperRe: how to get more power out of a hgt engine
are you talking about the 20vt injectors ?

Yer...
well im getting some anyway and also getting it chipped..so will let you's know the outcome..if it dont work,it dont work..but we'll see lol


Ive also got a spare head now so will be getting that polished and ported soon :)

hi,
in my opinon avoid 20vt injectors untill you get fuelling probs they will cause more hassle than they are worth till that point, i have a fc performance chip in mine. Mine was the first he did, i travelled to bristol to have it live mapped and i can defo recommend one as the improvement was massive. power and torque both increased, so did throttle response and mpg is about 3-5 miles extra per gallon just so much better as a drivable car.

hope this helps
 
Hi mate,yer im going to get 1 of those chips for it,Been in touch with 1 of the guys who do that chip and he reckons with the freer flowing exhaust i got and the K+N ind kit,estimate around 160-165 with the chip in.

Thing i wana know tho is,its a simple plug and play..now you said you had a live map put on it aswell..can you do that afterwards? cus i thought the chip was already set up.hence the name plug and play?

Cheers

Just been reading this thread :

Is it worth gettin the exhaust de-catted or not on the hgt and will it work well with the chip?

You have two choices with the mk1 hgt (mk2 is different)

live map, the car is mapped to your specification and to your mods, your looking at driving to Bristol, looking at around 149 quid (possibly cheaper) and he will use the best part of a tank of fuel.
This one he plugs his laptop in to the ecu and emulates the chip, with the aid of a wide band lambda senser and a hole host of other kit, he gets the map right and then flashes it to a chip, the chip is then installed

or getting the uprated chip off him that's a very good, but generic map. this will involve taking the ecu out of the car and using a icu extractor of 2 very small screw drivers to remove, and then install the new chip
 
james at fc performance used my car to create the map that is used on the chips he now sells it was done by live mapping out on the road, i travelled to bristol and was the 'test car' if you will, he had it for the best part of 5 hours, if you get one you will see a big improvement on power, torque, throttle response and slightly improved mpg

if you want any more info pm me

As a specialist Fiat tuner they will have got the most power out of the engine and a good even spread torque curve, Without risk of causing engine damage. ;)
most chips wont give anywhere near 10bhp despite their claims.
 
If you cut though a lot of the chaf, there is some good information here

I just lifted this from the thread

I'm one.

Chip arrived very quickly and well packaged*
Installed in less than ten minutes, no issues, just the standard reminder to be very careful and look at the orientation of the old chip (notch in the corner). Easy.

First day I could only give the car a quick 20-mile test on damp roads. The chip "seemed" to make a difference and there was certainly something different happening in 3rd and 4th but I thought I needed to do a fair few more miles and preferably in the dry before I could comment on the forum.

Today the proper testing took place. Impressive!

First thing I noticed was trolling through a local stretch of 40mph road, I'd inadvertently left the coupé in 5th gear (as I would in the turbodiesel I usually drive) instead of 4th gear for the pick up at the end of the speed restriction. The car still picked up niftily, and certainly better than before thanks to the extra torque.

3rd gear is now even more magical than before, and the chip in combination with the cam variator at 4k rpm is wonderful! Example: Vectra (twin exhaust job?) with the bored sales rep at the helm was sitting on my rear bumper as we went from a 40mph limit to a 70mph limit. 3rd gear engaged, 4k rpm dialled in and he was a dot in my mirror, despite me only hitting 70mph.

Motorway flexibility is greatly improved, you know the score, you're pootling along and some geriatric nugget in a 1.0 litre Micra has the cheek to enter the "coupé lane"? In the past, even with the revs sitting above 3k rpm, the coupé seemed breathless as she picked up speed again. Not any more!

Fuel economy? Don't know yet but there is a good test coming up soon, an identical 400mile round trip. The last time it was done, a few weeks ago, I achieved 31mpg with a few playful cam variator accelerations, so I'll report back on what the chip achieves.

Would I recommend a chip from Flea? Hell yes! It's a bargain! Trust me, I have always been decidedly underwhelmed by the performance of the 20v NA. Bear in mind I am used to driving stuff which is a bit nippier but I still expected this car to perform better than it did when it was standard. Thanks to Flea's hard work, the car is now beginning to feel more like it should have done when it left the factory. As someone else has already said in this thread, what on earth do you have to lose? If you really don't believe me or Flea and you don't believe the chip makes a difference you can always Ebay it and lose very little for the experiment. Or you can go back to driving a 1.0 litre Micra!

Oh, just one other point, insurance. It has cost me a mere £15/year to add the chip as a modification. The gain in driveability and torque makes that a small price to pay.

Now, all you 20v NA owners, what the heck are you doing still reading this? You should be bombarding Flea with orders!
 
Hi guys been a long time since i was on here.

where do i get one of these new chips like as im interested in seeing the real gains as i collect yet another hgt on the weekend and after my gearbox goes in i want to start tuning it again, ill be transfering most of my old stuff incl my modded 20vt inlet and want to see if these guys can get me the best from my mods so i dont have to get another motec as money is tight lol

new car will have:

DE cat
Free flowing exhaust
Custom manifold
Modified 20vt inlet plenum
Modified 20vt throttle body (incresed bore by 5mm)
Denso plugs
Itg Foam filter
Re-Profiled cams (inlet cam slightly advanced to suit)
Adjustable fuel reg

thats all im doing to this as i am still buildind my other engine up but wanted something a bit poky while i did it..

cheers
