Tiguan IS38 and Big turbo upgrades

[INASNT]

Hey team, I ended up buying IS38 - 06K145874G revision. It's second hand but low mileage and internals looked great too.

Basically my next step is to do Stage 3 this week so I will let you know on specs and costing.

Here are some pics of the turbo.

Bought this off Jacob Cherry?

Mine is a G Revision - 8,000kays no issues so far - still bringing smiles to my face.

Great to hear, looking forward to stage 3, initially wanted to just do a simple JB4 tune but decided otherwise.

No, I got it on Gumtree, different name.

So, my APR stage 3 is on. Car reflashed from Stage 1 to 3 with new APR dumppipe, APR intercooler, IS38 turbo (Rev F), Racingline R600 CAI, Racingline R600 intake hose, Racingline turbo delete and Racingline high flow turbo inlet. Also put an 034 rear swaybar on too for good measure.

Picked the car up on Friday afternoon and my initial thoughts were . . . . Dear God, what have I down. Lacklustre, laggy, seemed worse that just the Stage 1 - I was really disappointed. Put the car in the garage, turned the TV on, sulked and didn't drive the car all weekend. Didn't know how to justify to my wife where the money had gone. Couldn't justify it myself.

This morning, had to drive a short distance to drop something off and the car felt perkier. Then the CEL came on - brilliant. Rang Vince at North Shore HiTech and took it straight in. We ran some tests and the error code was the turbo waste gate controller solenoid. Did some checks - wouldn't you know it, the connector clip had popped off and the first error had occurred on Friday but the CEL only showed next time the car was started. So no waste gate control - yup that would explain it the awful performance.

Took it out again this afternoon. Holy &*^$(#*(^# - what an animal. Still got the grin on my face.

I was worried about lag with the bigger IS38 as I loved the response of the IS20 - shouldn't have worried. Power delivery is actually smoother than the IS20 with Stage 1 which had a tendency to snap on really hard around 2500rpm which sometimes unsettled the car. No such problem now. Power comes on noticeably from 1500rpm and feels strong as it builds past 300rpm. And wow - what a difference to the top end. The IS20 used to run out of puff after 4500rpm, but now it is still building as the tacho swings past 6000 rpm.

Revised initial impression is that this is a well balanced street car. Sufficiently responsive down low for day to day driving which sufficient top end to make one smile. Its got a nice snarl now when the foot is down, but I also love that it is still nice and quiet when just cruising around. The overrun crackle with the pops and bangs tune is pretty cool too.

Next thing is to get out the dragy and get some times out of it to see what it is actually doing. Hoping for a flat 4s to the 100 / and 12s for the quarter mile with launch control. Will have to take it to the Creek as well to see once restrictions are lifted.

Ecstatic with the performance. Also great having your tuner/mechanic only a few kms away - one of the reasons I decided to stick with APR and not go for a custom tune - the APR tuner is only a suburb away.

Good work. I was going to go for a 550hp hybrid but happy I went with a P version IS38 instead.. Interested to see a dyno graph of your tune if you get one done to overlay with mine.

If I were in Melbourne I'd happily go to the dyno you use for a back to back comparison.

I'm aiming to get across to Silverwater Automative in the next few weeks for a dyno run so will post up when I've got it. I'll also do a few runs with the Dragy in the next few days to see what it says.

Regarding turbos, I originally wanted the Littco L380 which is essentially the IS38 with larger thrust bearings, thrust washers and 45mm compressor which is known to work well with the APR Stage 3 tune but there was no stock with Littco and none due for some time so I grabbed a Rev F spec from the UK. I'm also curious to see how the L380X works with the Stage 3 tune but initial info on this is not positive at this point (apparently the turbo responds really well to another custom tune, not the APR Stage 3 tune).

550hp sounds nice, but with the extra 200kg over the Golf I reckon the lag would be problematic for a responsive street car (and lets face it, the Tiggy is no track car!)

Has anyone tried Turbo blanket here?

Lab study says it works. What do you guys think?

I had one installed on my TTE475. It's got volcanic rocks in it.
My main reason for getting it was for trying to keep as much heat out of the engine bay as possible after spirited drives.
I can't really say if it improves performance like some sites and videos suggest, because it was added when the turbo was fitted.

I think if you were tracking the car then there may be some benefits, however for just short squirts I don't think you would notice any difference.
