Lupo GTI modifying from scratch advice

Recommended Posts

Ok first of all, hello everyone.

Just bought a lupo GTI and am obviously interested in modifying it. Have been browsing and have most likely come to a decision on the mods I would love to purchase - they are as follows.

Kam Racing Manifold 200 cat

Kam Racing "Grams" exhaust system

BMC CDA induction kit

Eibach Pro lowering springs

Uprated Brakes (recommendations welcome)

Some sort of remap (would this be required/increase performance after the aftermarket parts are fitted)

 

My questions at hand are,

1. How much Horsepower gain would I be yielding with all these modifications in combination?

2. Is there anything I am missing or you think would be good for the build?

3. How much would the following modifications cost to be fitted?

4. Any personal experience on the above modifications?

Thank you so much In advance!

1. Not much. Maybe a couple of HP.

2. Most of that list will affect handling.

3. £1k+

4. Yup. Concluded most is cosmetic but cool.

to get more hp, you need to mod the lump. No question. Cams, inlet plenum, exhaust manifold, injectors, map, compression ratio. Even then you'll only get maybe another 20hp. To get serious power you need to breathe on it.

Not much for quite a lot is the answer.

Your engine mods make it breath a bit better but do nothing more, a remap might get you 10% more. It's not a turbo engine so remap gains will be small. You would need some expensive engine work to go higher. You would have to spend £1000s to get 200+ out of it, cheapest option quickly becomes engine conversion to something with a turbo on it if you want big power.

A well set up GTI with 140 - 160hp NA engine is still a damn nice car to own though.

As people say, 20-40bhp with the right mods. But it makes them a different car to drive, mines currently 141bhp and its a hell of a lot faster than a standard GTI. I’m hoping for 160bhp now the head and cams are on. The only guy i’ve found who will map these ECU’s is Wayne at Chip Wizards, mine goes to him on the 21st so i’ll report back then👍🏼

Sounds good, im hoping for around 140hp with the mods I have listed above - what are you currently running? Also would be great to have a link for the head and came. Will look forward to hearing your results!

140 out of a 135 car, healthy engine might give you that.

Aim for more but negate the bhp figure and focus on the torque.

People say standard Gti's come with 130 - the Kam manifold and system is a 10bhp bolt on part, so in theory if your engine is healthy, your at 140 already.

But as already said you wont get the best out of it unless its re-mapped. I got mine already converted with the Kam manifold & system, fast road cams, short runner dbilas intake manifold & cone filter +cold feed  - it was re-mapped and apparently has 160bhp  - Sadly the PO did not give me the name of the company who did mine, but assume it was somewhere near Newcastle or Sunderland. Driving it around town its nice and docile it all just goes a bit mad above 6k revs when the cams kick in.

All the items in your list are bolt-on, so shouldn't take too long to install. Unless you recently replaced the shocks I would go for a kit of matched springs and shocks or better still coilovers - rather than just springs alone. 280mm carrado G60 disc conversion is the the best cost/improvement there is.  If you were to go as far as cams, look into getting the head ported - intake is already pretty good, but exhaust is apparently restrictive.

When it was dyno’d it was just a 4-2-1 decat manifold, Intake with a cold air feed and lightened flywheel. It’s now got a port and polished head, polished inlet manifold and Piper cams. 

 

I highly recommend a lightweight flywheel, my favourite mod for mine👍🏼
