why go bigger and create more lag when you can get a hybrid

+1, look at modding your engine first pal, you dont want to spend on turbo upgrades when something could give out i.e. cams, rods etc. check the projects section for inpsiration, rockymonkeys got me considering a rebuild now as well  :lipsrsealed:  :grin:

1999 - 2001 it's likely to be a k03 turbo.  2001 onwards it's likely to be the k03s.  Highly unlikely you're running a k04.  If you were you wouldn't be complaining about not having enough power.

Btw, Revo maps are absolute turd.  Get a proper one, then decide if it's good or not.

Rtech can provide generic revo maps or full custom maps (which will givee better results as the to your car)

Never once complained about not having enough power thanks.

And okay I didn't ask that did i? No. No need to be such a knob about it, I was purely asking a question and was hoping for some reasonable replies as I do not know too much about it.

You posted a question without giving any of the information required for anyone to give you an informative answer.

Nige was correctly pointing out (based on your replies of: "Standard turbo" and "I believe ko4") that if your turbo is standard it will be a KO3 or KO3s NOT a KO4.

You've said you want a bigger turbo, i.e. you're not happy with your current setup, most people would be happy with a KO4 which is what Nige also suggested. To run a KO4 on a MK4 it would need custom mapping, not a generic REVO map, again something Nige said.

I'd say that is a reasonable reply. :rolleyes:

im not sure if they really need the work from revo tbh mate, nick is well capable of writing his own maps and in my opinion better. you could be right though and perheps he deals with them i`m not sure..
i just can`t see the likelyhood of it.

RTECH have Revo for those that want a Revo map specifically and it also allows them to provide remaps for engines they haven't developed in house maps for yet like the 2.0L TSI in the MK6.

Simples! Be quite interesting to see what similar specs are getting out of the r-tech setups. When you get your car back if you remember ha can you pm me your dyno results? And a rough spec?

Are you getting train back or a lift?

Did you have to book wellll in advance? Was it a price or an estimate and do you know exactly what your going for or are you giving it to them and they will setup what you have to its best output?

Many others you know gone down?

Never once complained about not having enough power thanks.

Why would you want to fit a BIGGER turbo with MORE BOOST! If not to try to obtain more power?  Have you uprated the brakes in preparation for the extra boost you want?  Obviously you've upgraded the intercooler as well, and the hoses, and have fitted a Forge re-circulating valve as well as upgrading the exhaust from turbo back?  Have you figured out which turbo your car has yet?  I've got a feeling you're about 19, so would assume it's something cheap, probably an early AGU with the k03 turbo, so with a re-map you won't have cracked 200bhp yet.  Your best bet, and best value for money option, bag a k03s and get it refurbished.  Pop that in with the mods above and drive to R-Tech or Carbon for a customised map.  All going well you might see nearly 230bhp.

I do not know too much about it.

Seriously, there's a huge amount of things to think about when upgrading for big performance gains.  Assume you're contacted your insurance company and arranged a quote for all the upgrades and extra power?

tbf pal your not the only one thinking this way, if below 21 hes insurance will laugh at him with all proposed mods tbf, im 26 next week, tested the waters on mods that im fitting and only greenlight are the ones i'd want to go for, their quote includes cover for the following gen R32 front, splitter, sideskirts, anni rear valance with cut out, all sprayed, 3"tubro back (when its eventually fitted  :angry: ) TIP, forge actuator, DV catch can, engine deletes all classified as engine mods, aftermarket ARBs front and back, aftermarket 18s, 15mm spacers up front and 20mm out back, lowered on shocks and springs, tinted windows and boost gauge all covered under 400£ with LIKE FOR LIKE replacement. thats with 3-4 yrs NCD's and driving experience of 8 yrs

tried the same on comparison websites and on one occasion i was quoted over 15k so, in relation to this thread, all declared mods better be declared otherwise you are theoretically cruising about with out insurance, which means your vehicle is illegally driven, and if you've more than  brain cell that means you are not a legal driver, 9 points max on your license for not driving in accordance with the law, car seized and impound duty of 25£££s per day and if not collected in 14days its off to the crusher   :cry:

Right IMHO dont bother chasing power until your insurance starts coming down dramatically make your car look nice first otherwise you wont be able to afford the inusrance greenlight dont insure until your over 21 so spend your time getting it looking nice then start going down the power route cause at the end of the day your better off being insured properly cause at 18 i am gonna guess you have been driving less than 2 years so that means if they give you 9 points max you will lose your license

Audi S3 has a k04 turbo (k04-001 i belive) which is a streight swap i belive.

i also belive the mitsubishi evo (cant remember which year) has a turbo thats a relative streight swap and belive one of the scoobys uses the same turbo and costs alot less.

the k04-001 is proberbly the easiest turbo to fit.

in essence you can fit any bigger turbo you want, its just youll have to look into things like custom manifolds/ different manifolds, maf sensors, throttle boddies etc.

i belive toby put a k04-025 on his golf, but he spent a fortune on his, think he fitted a relentless manifold, badger 5 throttle boddies different mass air flow sensor bigger cooler etc etc etc.

if your really that interested in fitting a bigger turbo then drop him a pm, equally send nick or someone from rtech/carbon chip a pm on here, sure they will talk you through some stuff. equally you could email a local turbo specialist, they will know what fits and what doesent and any work required.

but as stated, fitting new turbos comes after you have done other stuff imo.

start off with full exhaust system(not just cat back), cooler, boost pipes, diverter valve, injectors, custom maps. look at induction (either induction kit or pannel filter, have to weigh up the pros and cons and see whcih you think is best), bigger indiction (3" maf etc.) then look at extra cooling WMI etc. then before you start to look at bigger turbos look at what you want to replace first, what power and boost you looking at, will it need new rods, will it need new cams etc etc etc.

Audi S3 has a k04 turbo (k04-001 i belive) which is a streight swap i belive.

i also belive the mitsubishi evo (cant remember which year) has a turbo thats a relative streight swap and belive one of the scoobys uses the same turbo and costs alot less.

the k04-001 is proberbly the easiest turbo to fit.

not the best advice then telling him to get a custom map before fitting a new turbo  :whistle:

Yes I'm 18 and your point is? Not being a knob but money isn't too much of a problem. I am sorry I don't know much mechanically about it and yes I know I would have to upgrade everything else I'm not that stupid. I was just asking to see what turbos could fit as I heard about on different models of cars they used turbos from larger cars in their brand etc...

If money's not an issue just buy a faster car in the first place?  Absolutely no effort required and your insurance will be lower than a Golf with a ton of mods.

Golf R32, Audi S3, or something bigger still.

why not? if he gets WMI then the cooling from that is going to allow him to run more timing and boost, a custom map wil account for that were as a flashed map will not.
same with any other mods, the map could then be coded to suit how the car is set up. and can be coded to how he wants and include other stuff, launch control, left foot breaking (not sure if you can get it on mkivs but you get the picture).

obviously he will proberbly need another map once the turbos changed, but if hes going to go down an expensive route of manifolds, rods etc etc etc to fit a bigger turbo and go for big power it could be an on going project and the custom map will give him most power for the current set up, or he could do them mods and think actually its pretty fun as it is so I wownt spend all that money on a bigger turbo and go splash it on a few beers or a holiday or something...
