Gt2x

[Kevgrady]

Hi got a mk 3 ibiza cupra at the mo with a few mods and looking to go for the GT2X turbo conversion in the near future but would like LOADS of advice first.

1. Is it worth it?
2. Do you get turbo lagg? (if yes how much!)
3. What will i need ?
4. Is there a company that do the conversion?

Also anything else you think i should know!

Cheers peeeps

Eliminator GT2X

Have a look on Vortex, quite a few of the yanks have them, there seems to have been a few problems with the turbo's going.
They are available either direct from ATP or through Big Boys Toys or Star Performance, seem to be getting around the 285 Bhp Mark but are from what I have read quite laggy, not spooling fully until 3300rpm The fitted and mapped price comes to about 3K so not a cheap option, you will need an FMIC, minimum 2.5" DP/Cat, 386 or 440cc injectors and Jim at Star recommends a boost controller.
Was looking to go this way but did not like the prospect of a lot of Lag hence I am going with a TT K04 remapped to about 270 and 300 Lbs/ft ( hopefully)

GT2X isn't laggy at all (you think full spool by 3300rpm is laggy?), I went from a K04 to a GT2X and found very little difference in the spool, it's a much better turbo though, had mine a year now and am still happy with it, had zero problems in that time, turbo still 100%, no cracked manifold, nothing. Had a straight line drag with an Impreza STi from 70mph upwards and pulled away from it, in an Ibiza it should be pretty darn quick. Mine made 287bhp and 309lbft at 1.35BAR of boost.

I agree with RobDon,

Not had any problems with mine either, mine made 284 BHP and 296 ibft at 1.3 BAR of boost,

K04 wont spool much sooner.

I found that with the manual boost controller it was laggy, b ut with the apexi its spot on.

Power is strong all the way to redline with no pressure drop.

Blows away alot of fast stuff including M3's, subaru's, evo's, porsches etc etc
Boost controller is a must on this setup.

You will need the following:

ATP Manifold
ATP GT2X Turbo Kit
2.5" DP and sport CAT
Cat back exhaust
S3 Turbo intake pipe
S3 MAF
Induction Kit
S3 Injectors
FMIC
4 BAR FPR
Boost controller
Remap

Think thats it.

[RobDon]

Yes, the Apexi deffo makes a difference, holds boost very well, cracking bit of kit.

Agreed

Matt who done all the work on yours?

 

[ibizacupra]

Apexi is just a controller solenoid same as N75 in the business end. nothing its doing is better than the OE control, presuming you are able to map it accordingly. Apexi gives it to DIY level, which is its advantage, so long as it does'nt fight the ecu in other respects.

Rob, what boost does this turbo hold at the red line.

Me

 

[Kevgrady]

No good to me then , is there a company out there that do the conversion like jabba do their ihi?

GT2X fitting

Star Performance will do the whole package, fitting, mapping, boost controller or full Apexi regarding costs, this is an quote from a an e-mail from Jim at Star re pricing

'David, to supply & fit the GT2X along with the ATP manifold is £1698.00.
Supply & fit apexi is £385.00.
Mapping is £599.00.
This kit is good for 275-285bhp

This does not include the S3 Injectors, DP/Cat, exhaust, FMIC, TIP, FPR as I already have them all.

PS Matt / Rob didn't intend my post about the turbo to offend, just what I had read on vortex and a tuner I use reckoned they have 6 ATP Manifolds awaiting refunds due to cracking.
Have you both upgraded your Fuel pumps to 4 Bar as well? I am planning on using the TT fuel pump module in the 3 Bar sender unit / housing if it fits

 

[RobDon]

Still on stock fuel pump with 4-bar reg, S3 injectors, 75% duty cycle. 6 manifolds out of how many sold, thousands I bet. HKS turbo manifolds crack so it's nothing new really, even HKS stuff fails.

Wild Willy - can't give you an exact answer but mine boosts to 1.4 BAR and hardly tails off towards the redline at all, maybe still 1.1-1.2 BAR at 6500rpm, it's definately still over 1 BAR, it does hold boost very well, no BS. My old K04 used to fall on its face after 5k rpm, GT2X doesn't.

No offence taken, I just get miffed when people say things that are not strictly accurate!

 

[h17och]

my k04 has 1.3bar at redline! why was your k04 givin up at 5k?

Hooch

Not doubting you buddy, but do you have any logs as my lcr k04-02 doesn't hold anywhere near that at the red line.

 

[h17och]

will sort some out 2mz

any news on these?

any news on these?

My k04-023 turbo will hold a maximum of 1.13 bar at the red line and i think this is a good figure. I just can't see any unmodified k04 to hold 1.3 at the red line. I have a hybrid k04 to be fitted soon and i doubt that it will make 1.3 bar at the red line. The other guys are getting 1.2-1.25 with their hybrids which is quite respectable.

dont slap me, but whats that in psi?

My dodgy maths calc reveals, 1.13bar x 14.5psi = 16.39 psi.
Its totaly maxed out at this level.
