Advice on 1.8t remap/upgrades you had

What did you have doneon what engine, what did it produce and how would you rate bang for buck?

Real cases please not speculation.
I am weighing up my options, its a 180bhp standard.

 

get it Revo'ed!

 

Custom Code, REVO, APR, Jabba..... lots of choice

 

What year is the car. Also what engine code is it and is it DBW?


You could be looking at betwwen 200 and 225bhp depending on model and spec of car.

Its an AJL 180bhp, cast internals large port head. K03 turbo.
Its in a 1999 a4 quattro so no VVT or DBW.
I was thinking
1) remap - might give me 200bhp before i need to change turbo or I/C -500
2) fit a KO4 with bigger injectors(440's) remap - easy 250-300bhp - less than a grand
3) get the cheque book out and IHI the beast and get a chargecooler.

3 is not an option (yet)
1 doesn't represent value for money
2 requires major surgery (not a major problem)

are there any other options?
Don't want to end up with a peaky engine that is flat as a pancake until it hits 4500 revs.
What are the remaps that you have had like?

 

If i were you i'd go for option 2. Your car won't make much more than 200 bhp, my mates girlfriends A4 made 205bhp on the rollers with a MRC re-map.


The K04 isn't laggy and has quite good low down torque. If you change the I/C on your car toothen you should see 270+ easily i would have thought. I'm getting my Golf re-mapped soon so i'll have to see what that does on the rollers

cheers, i am watching ebay as we speak!

 

Theres a k04 here

going to be running stock 150bhp for now...and then get it Revo'd!!!

 

yeah but a revo'd 150bhp gets a hike to 190-200bhp for your 500.
If i chip mine which is already at 180, i only see 10-20bhp for my 500.

not worth it.
I am exploring the manifold market at the moment (see other post) as I have discovered there is not a manifold on the market for longitudinal 1.8t engines to allow turbo upgrade to KO4 or IHI.
bugger!

 

hi i used jabba thay took my 1999 mk4 golf from 162bhp up to 210bhp with bags of toque, she still going strong

just a remap?

 

From what I recall reading, if you bolt on a K04 to a once equipped K03 1.8T, you wont be able to make near on 300bhp due to the compression ratio and inlet manifold/cylinder head design (i.e. large port for most), which is why you see most 1.8T K03 > K04 after a remap only making 240-250bhp. K03S upgrades produce around 230bhp but the boost doesn't fall off at 5500rpm like the K03 does.

1.8T small port and K04 can make upto/around 300bhp (compression is slightly lower in the 210/225 1.8T's)
1.8T large port is best used in conjunction with a large turbo, 300bhp+ (with relevant internal mods)

Think that's about right, correct me if I'm wrong someone.

 

Pitstop developments do a custom remap service on any car now, they are doing my car (when it's back together)

Just spoke with steve and it'll be 425 for your car

PM me for there contact details

 

AGU engines (150spec 9.5CR) can make good power >250bhp with a K04 turbo if you have big injectors and remap/EMS to do it properly.
Also, use decent fuel, ASDA best 95RON won't make much more power bacause of all the ignition retard due to det.

From my experience and cars I have seen:
K03 turbo's are good for about 200bhp,
K03s about 225-230
K04 about 280

Injectors are about the same (150-200, 180-230, 225-300)

Inlet manifolds are the same design, and throttles are the same size. Port size is smaller on later engines - but I think the engine code spreadsheet has mst of the data on this.

And use a decent intercooler - charge temperature is bad...

 

I had a 2003 octavia VRS

Jabbasport remap at just under 3k miles 180 to 230bhp

Then added a jabbasport 100 CEL sports cat and 2.5" dp with 2.5" powerflow system.

Carbonio airfilter and bailey diverter valve.

Final remap at jabba with there boost controller fitted 246bhp at just under 10k miles.

Very hapy with the performance but clutch went at 21k just before i sold it

 

dub vrs - what did all that set you back? from your list that is 2 remaps, cat and exhaust, filter and d/v.
Individually that is close to 2k.
For 2k I can get all the parts I need for an IHI conversion and have change towards a custom map.

"1.8T small port and K04 can make upto/around 300bhp (compression is slightly lower in the 210/225 1.8T's)

I don't know anyone running 300+ on a KO4, but all the tuners say its a turbo that doesn't react well to high boost tuning. Too fragile apparently. most of the remapped 225 tt's don't break the 300 barrier.

The cost of me converting to a KO4 is not too far away from a GTS28 or IHI conversion, its the remap I am concerned about.

 

AGU will run K04 fine on 9.5:1, as long as the intercooling is OK, and best to keep to Optimax or Test 99RON!

Biggest barrier is fuel injectors though, and of course fuel pumps!

 

has anybody got the link for the engine code spreadsheet??
I've got a audi a4 1.8t with a k04 turbo onit, pulls ok at the mo but just need to get a remap for smoother power.
