Me too! Doesn't fit in a Corrado though :-( Well, it might with some major slam panel fudgery. I think you should try cams mate. Schimmel 264s :-) Really tempted by a nice 24V with the shorty intake, 264 cams and GT35R. Keep the peak torque within the limits of the 02A gearbox (around 350lb) but extend the top end!
-
That's better! Much better pics :-) I stand corrected, that is a water cooled turbo as Matt said. That doesn't look like Stealth Racing kit to me mate, so it could be a T61 as originally said, it's certainly the right frame size! Stealth use the SPA Turbo cast manifold and an oil only T4 turbo. It looks like good stuff. You'll need an adapter to to convert the 2 bolt wastegate fitment on the manifold to a 44mm v band fitment on the wastegate. ATP sell them.

Had a quote for my supercharger and manifold wot do u think ?

£5610 for 310hp is extremely uncompetetive these days!! -
It's not a T61 or a GT. It's a T4 of undisclosed origin, but does have a 360 deg thrust bearing, which is all I can tell you ;-) Stealth's is an oil only turbo. Been out in the Stealth Demo and it spools a little slower than my GT35R. Makes good power though, 430hp @ 15psi seen on one car, so has the same grunt as a 35 up top. Yes, £450 for all that is a very good price.

atpturbo sell downpipes

You won't get 190hp from a 97 engine without the 97 ECU to go with it.

Genuine VW and OEM are one and the same thing - Mahle.

OBD2 engine giving more power = Fact K&N giving 5hp = Myth ;-)

Agreed on the short runner, well, for me personally at least as I'm not a fan of the all or nothing throttle response of the 24V below 3500rpm. I must say, of all the 24V Turbo stuff out there, I really like the look of the HPA stuff - http://hpamotorsports.com/ft425-special.htm Going back to the plastic intake, I really doubt that will handle a bar of boost long term, especially from a turbo. Have you seen how much a normally aspirated R32 plenum collapses when you blip the throttle!! That is the dissapointing thing about the MK4/MK5 engines. They're built down to a price.
-
Agreed. By the time you've adapted a LHD American kit to fit a UK car, you'd be better off just sourcing the right bits individually. It all hinges around turbo manifold choice. If you want an easy fitment with a short runner, go with the ATP mani. If you want an easy fitment with the stock inlet, go with the SPA turbo mani. The rest is just a case of picking your bits and peices and software / management.
-
Agreed. Any gains with exhaust size on naturally aspirated engines would normally be found at full revs and full throttle. It also depends on cam overlap too. Wild cams are good at creating a vacuum below atmospheric at max torque revs, which sucks out exhaust gases, but at lower revs, some exhaust gases can get pushed back into the cylinders, which dilutes the intake air/fuel mix, reducing power. So exhaust tuning on NA ties closely with cam tuning. And people who claim an exhaust is restrictive should really back it up with actual back pressure measurements (pressure sensor in the exhaust

Seriously? Hmmmm..... defo tempted now you've said that. Got a 2.8 4 mo lump sat in the garage and finding a 24v short runner that fits a Corrado was the only thing holding me back, but now I know the plastic intake can take some boost.....hmmmmmm :-) If I'm really lucky, all I'll need is a 24V T manifold from ATP and the downpipe will need minimal changes. The management I'll just transfer over as it's standalone..... Wish I hadn't read this thread now...... LOL! Have you got a build thread on yours mate? As you sig says, when did that happen? LOL!
-
That much? I've seen pictures of them blowing apart at 10psi. Mind you, that was with a turbo.
-
That's why people use V band joints these days, but yes, a "4 bolt" outlet is a standard size depending the frame size of the turbo etc
-
You're getting compressor surge with that valve? That ain't right. What turbo is it?
-
Yeah don't get an under drive pulley set, it will just cause problems. Light pullies in the standard size are fine.
-
First post under yours says it all. Really not worth it, A lightened standard diameter pulley is a different matter. Some MK2 VR6 owners fit them as a matter of course due to the chassis leg clearance problem and they often report good things. As said, with a lightweight flywheel, you do notice the difference. You would be amazed how quickly the VR6 spins up with light pullies, light flywheel and the PAS pump disabled. I am actually looking into a manual steering rack and electric water pump and just run the alternator off the crank.

This forum is full of turbo talk. Use the search!

Are you on commission or something? LOL

You should hear my Tial 50mm when it vents :-) But it's more of a darth vader gaaaaaarsh than a chavvy Psssshhhtt. Big flow :-) Agreed though, DVs can be annoying, but so much easier and neater pipe work..... As for open WG dumps finding more power, it's like the Hi-Fi nerds who claim to get massively better sound quality from £100/meter speaker cable, compared to 80p/meter standard QED 79 strand, LOL!! It's all in the mind. I keep saying this, but if you've got 400hp to begin with, do you really think you are going to feel another 10hp from an open WG? I don't think so :-) If you ha

This is their most commonly used valve - http://www.forgemotorsport.co.uk/content.asp?inc=product&cat=0006&product=FMCL007P And this is the one I used for a while, which is a very nice valve and stopped surging on my GT35R - http://www.forgemotorsport.co.uk/content.asp?inc=product&cat=0006&product=FMDVSUPR
-
What size turbo is it? Personally, I feel nothing less than a TIAL 50mm or Forge's biggest recirc valve will do for GT30 upwards :-) I ran the usual Forge 007P for a while and it was surge central.... it's way too small.
-
He he, that is the most common misunderstanding about turbos :-) Wastegates don't make a noise. Well, correctly installed ones of a decent brand don't at least. Compressed air bouncing backwards off the throttle plate and over the compressor blades is what makes the noise :-) People pay money to deliberately shorten their turbo life to get that noise :-)
-
I'll bet!! Quite a handy motor for boost the R32 as it's intake changeover point coincides with the boost starting, so you get the best of both worlds :-) Just a shame there isn't a metal version of that plastic intake though....which still has the variable gubbins in it.
-
Single turbo conversion imo. Superchargers work well too as the R32 has a lot more grunt below 4000rpm than the 12V.
