atp gt2871r turbo kit

[2crazy]

ok i guys 1st off i drive a seat leon cupra mk2 and it's stock standard at the moment. i have the opportunity to get the above kit at a great price but i need some info before i go ahead with the build. please bear in mind that i have a budget so will not be doing internals.

these are some of the parts that i would like to use....
frc or giac software
atp gt 2871r turbo
atp cast manifold
atp induction
atp downpipe/decat
s3 cooler
autotech fuel pump
uprated dv
oil feed and water feed lines
standard injectors (i think they are same as the s3)

1. is there any other parts that i need to add?
2. will it be safe to run on standard internals and what will be safe boost to run?
3. how much later will power come in as opposed to k04 and will it be fine for daily driving?
4. can i run standard cooler with setup until i source a 2nd s3 cooler?
5. i have eibach springs at the moment, so is there any other improvements i can make suspension wise?
6. what power can i expect? bear in mind it has to be within safety limits.

sorry for all the questions but i would just like to make a well informed decision, so any advice or tips will be highly appreciated.....

Thanks

You must be crazy mate , i would never change the K04 for another turbo as its a cracking piece of kit. i would simply give it the hybrid treatment, full stage 2 plus and wmi. You'd be in 400 bhp territory with early spool to go with it.

i agree.

all you need is a

Perfomance downpipe (£500)-miltek/blueflame are popular
Performance induction kit (£300)-Evoms, ITG maxogen, forge twintake are popular
uprated HPFP (£300) autotech are the most common
uprated intercooler (£300-£750) (s3 is the cheapest, then there are the forge twintercooler, THS and APR to consider

pair theabove to a good stage 2+ remap and you'll be in an a very very quick car 330-360Hp depending on dynos

realistically thats only £2k for a potential 120Hp increase which is riduclously good value for money

stick with the k04

1. is there any other parts that i need to add?use rs4 injectors instead (peace of mind/proven to higher bhp)
2. will it be safe to run on standard internals and what will be safe boost to run? not really 'safe' wouldn't last long before a rod gets bent/psi not sure given the larger nature of the turbo
3. how much later will power come in as opposed to k04 and will it be fine for daily driving? a fair bit of lag, noticeably more than the k04.
4. can i run standard cooler with setup until i source a 2nd s3 cooler? not advised you'd definately be wanting the optimum hardware with this setup
5. i have eibach springs at the moment, so is there any other improvements i can make suspension wise? get a coilover set with adjustable height &dampening
6. what power can i expect? bear in mind it has to be within safety limits. cira 400 with the above. you wouldn't want anymore without internals

Hybrid K04 would be your best bet, very responsive and a good daily drive. with the potential for 400bhp +.

nice stage 3 turbo eh same as the turbo used in APR (ie like danGB) good luck mate good to be different eh strange though even though you got a parts list you still ask here ...hmm

thanks for all the replies

the reason im thinking of doing the above is because my car had slight accident damage and in the process the k04 got damaged, so currently im running a k03

to get a 2nd k04 where im from ain't easy even more so with hybrizing, therefore it will be cheaper for me 2 go with the above route. my only concern is the internals and lag.

You're not going to get masses of lag like a big turbod mitsubishi evo. It's just going to be laggier than the K04 but that's not hard because the K04 doesn't have much at all.

It's still going to be driveable so don't let that put you off. Just when you're running a big turbo you want to make sure everyone else is up to scratch or it's going to be a very very expensive repair.

I'd drive around on the k03 until you have sourced all the parts or got the money to get the full works including internals. You don't want to skimp out on something that may be hundreds, only to end up paying out thousands.

Best of luck with the build.

Perhaps get a readers ride thread going with your findings.

I'd speak to APR about software and even hardware, they might be able to shed some more light.

I just happen to know of an APR GT2871 MK2 Leon and a certain S2+ K04 MK2 Leon that had several blasts against each other recently on a test track, and the results were very interesting.

Be under no illusion a GT2871R car is faster than a K04 (it blew my socks off just how fast actually), but by the time it gets to be faster, the K04 car is some way ahead. and you are looking at being at approx 115-120mph before the big turbo car gets the advantage.

It is my opinion that unless you are going on a track, or using something that can harness the extra power and torque effectively, I would sooner have the smaller more usable turbo. As mentioned above, the K04 hybrid would probably be the best option ultimately although so far, they are fairly untested and unproven, not to mention expensive.

Me and dan did some runs rolling runs from 30 mph, 3 gear. The k04 pulls on it due to its responsiveness whilst dans was still spooling up. Once its spool up it is quicker, but by then its too late.

The BT car has its advantages on the track, with MPG, and driving with anger on the road whilst in full attack mode, but when say going for a blast on the motorway unless its in the right gear at the right rpm the k04 will be ahead until silly speeds

Yeah, exactly. From a 3rd gear roll on test, the big turbo car is going to be faster ultimately, but by the time it starts to pull in a K04 car (ie after 115-120 bananas), in reality, the smaller turbo car is gonna stay ahead until way past 150 bananas. I know that I for one dont like that many bananas as they tend to make you feel a tad twitchy.

Taking nothing away from big turbo because until you actually feel just how quick it is, you havent lived.

 

[Poverty]

Yeah remember driving dans car for the first time, once that boost kicks in damn its quick, and its holds boost to the redline

 

[vRSy]

what about traction with dans. is it an improvemnt over the k04 because of the lag?

youd be advised to uprate the clutch and gearbox with 400bhp

One guy in Moscow have an expirience with 2871 on octavia rs - he can't pass 330hp and have much much troubles with custom software. (he already have forged internals and all bolt-ons like pump, fmic, exhaust and etc)
Also he told me that it spools up only at 4000rpms.

I think that if you want 350-360hp - k04 and if you want more than 400 - 3071(76) with external wastegate, but not 2871!

all that shows is that who ever has tuned his car is absolutely rubbish.

DanGBs Gt2871 made 391Hp on Dyno dynamics rollers(which read lower than most other rollers) this was on a rolling road day in shoot out mode where all the k04 stage 2+ guys were making 330-340Hp maximum.

Ive been in two k04 converted octavias that are running 330Hp and have no issues staying with stage 2+ k04 cars.
