The Forced Induction VR6 thread

Recommended Posts

And I thought Schimmel's cams gave good results but a 189whp gain is rather impressive!

To save you reading all the posts, the car is a 12V VR6 turbo running Garrett GT42R @ 35psi, EIP big valve head etc etc.

 

Still making power at 8300rpms :cuckoo:

 

I want those cams, let me me know when you put your order in kev :lol:

Never seen a goat idling - do they get sort of horny? :lol:

I notice the power drop-off is very abrupt, regardless of cam type, presumably a lot of turbulence developed somewhere?

Or turbine limit reached?

hi all new to site

I have had my corrado for a year now and its time for more power,want to turbo but no to sure of what to go for kit wise and were to source it,have looked at supercharging,but I think I will want bigger power in the future that the charger won't do from what I have read on this thread.Looking to do the conversion with a friend who is pretty good with the spanners,what is the best way to start,is there a good quality kit out there that dose not need much modding,or do I need to get separate parts ie turbo intercooler pipe work ect,looking to start of with around 280 bhp and wind it up to around the 350 400 mark pretty soon after that I would think lol,would be interested in any bits that you boys have for sale to help me on my way, want to get it done over the next 6 months ,what sort of money am I Looking at to get this done.I am getting totally wasted by my m8s cars and this just won't do!This is what I am up against R32 MTM TURBO 400 HP, AUDI S4 MRC 550 HP and AUDI RS6 MRC 750 HP need to go play please help.

Thanks Dom

if you want an engine transplant Kev look at this http://www.pistonheads.com/sales/1125105.htm i know how much you like these engines.

 

well theres a challenge for you eh.

 

10 throttle bodies, yum, pure engine porn! That is indeed a great engine for a conversion. Not sure what to put it in though!

They are some seriously impressive cars to be doing battle with mate :notworthy: Good on you though, smash them! RS6s need all that power because they're such lard buckets. A decent VRT with modest boost keeps with a standard one easily, but don't tell your mate that :lol:

 

Well forget 280hp, go straight to a bar of boost and 400hp is my advice. And if you're playing with those boys, a GT3582R turbo is a minimum requirement! Not too laggy and capable of 650hp.

 

As for how much, depends on how far you want to go. If you want a "built" engine (forged rods and pistons and reworked head etc) it's going to cost a bomb. A spacer plate install will work but I wouldn't personally exceed 400 crank power with that method. The standard pistons can't hack it. The ring lands break.

 

A stock engine with forged pistons and stock rods will do 550 OK, then you need forged rods.

 

But before the rods, the gearbox should be looked at because surprise surprise, it can't hack anything past 400 wheel torque for long, but it depends how brutal you are with it.

 

I take it you must love your Rado otherwise you'd have looked at alternative cars for the power by now?

 

Once you get started we can advise you what to get and where from / how much etc.

Nice one,yes m8 I do love the corrado nothing looks quite so mean coming up behind you in the rear view mirror and I love the fact alot of people still don't know what it is coming for them.I like my bikes but I have recently broke my leg so going to bin them for a while,I think to start 400hp would do very nicely,don't want to go to mad at first and am quite poor compared to my mates so would want to keep engine standard as poss to keep costs down,my corrado has about 120k on it but had a top end rebuild at 111k seems to be a good strong lump,car has has full decat miltec,drilled airbox,are the only engine mods at present,what would you do first,what about ss exhaust manifold and stuff like that,or is it best to get everything together and then go about fitting it. What sort of overall price am I looking to pay,and how many hours labor in a conversion like this,need to be prepared for what I am letting myself into,as for keeping with my mates cars,if I can have them up the slip road I will be happy enough.

i reckon off the top of my head if you did the work yourself you would want 5k aside for 400bhp at least.... but worth every penny 8)

Thats about what i was thinking give or take a grand,so six would be good yes,I want to do a proper job and end up with a reliable yet very fast car,what about install time I need to know how nice I need to be to my mate who will do the more technical parts of the install(well most of it actually,my tea is that good).Also a list of parts would be good want to get started asap,I like the sound of that turbo kev mentioned in his reply,what else do I need,what set up are you guys running,I think it would be wise to go down a tested and proven road to save on hassle,do you ben and kev run the same set up?

Have looked at the set up kev has on the corrado database is this still the same?

i cant really help too much because i have learned most of what i know from this very forum and the people on here... im sure kev will come along and give you some good ideas!! our set ups are very different in many ways...

 

for cooling i would say a charge cooler though, i have a intercooler but its not as effective and on hot days i loose some power :(

Dom, if you want to copy my setup, I hope you're sitting down!!!

 

Basic engine hardware

 

Turbo - $1385 - http://www.spturboparts.com/aftermarket ... prod=16246

 

Exhaust Manifold - $390 - http://www.spturboparts.com/aftermarket ... prod=16349

 

Inlet manifold - $1175 - http://www.spturboparts.com/aftermarket ... prod=15954

 

Chargecooler - $1775 - http://www.spturboparts.com/aftermarket ... prod=16255

 

Dump valve - $220 - http://www.spturboparts.com/aftermarket ... prod=16270

 

Wastegate - $380 - http://www.spturboparts.com/aftermarket ... prod=16268

 

83mm Wossner forged pistons - £750 - http://www.tsr-performancestore.com/cor ... -728-p.asp

 

Plus machining / bearings / building etc, so another £500ish

 

ARP rod bolts - $110 - http://www.spturboparts.com/aftermarket ... prod=15909

 

ARP head bolts - $220 - http://www.spturboparts.com/aftermarket ... prod=15905

 

Gearbox

 

LSD diff - $790 - http://www.spturboparts.com/aftermarket ... prod=16013

 

And also fully rebuilt with new bearings and syncros throughout and a shorter final drive - £600

 

Engine Management and fuelling

 

Denso 1220 500cc injectors - $960

 

DTA S80 - £1000 - http://www.dtafast.co.uk/S_80_PRO.htm

 

Walbro intank W340S fuel pump - £90

 

Bosch 044 external fuel pump - $210 - http://www.spturboparts.com/aftermarket ... prod=16347

 

SX fuel regulator - $155 - http://www.spturboparts.com/aftermarket ... prod=16344

 

Plus a bunch of other stuff I can't remember.

 

That kit is up there with the best and not strictly necessary, but it's like with everything, you get what you pay for. I built mine to be as reliable as possible. Had a few teething issues initially but it's done ~ 40K since with no issues as a daily driver. I currently only run 13psi at the moment but that's enough to annoy most things :D

 

What I haven't listed are all the plumbing fittings, silicon parts, exhaust downpipe and system parts etc etc. That all costs a fortune aswell for the good stuff.

 

If you're mate can weld you up a 3" downpipe then you're laughing because that's the biggest hurdle from a DIY point of view.

 

Well hopefully that's some things for you to look at and mull over in the meantime!

 

Other guys on here have done VRTs a lot cheaper than I have, but I can't comment on theirs as I haven't seen them. StormChargedVR6 is another experienced big spender VRT man and his is probably one of the finest Corrado turbos in the UK :salute:

Thanks lads,there is a lot to look at there,whats the score with buying from the usa import tax and stuff,have bought stuff from europe with no probs but is the usa different?So if can I run this set up minus the pistons,lsd,but use the most of the other gear and run around 350,then get the pistons and other bits a bit further down the line and move up the to 400 and above?

Also there anyone near me with a vrt a could have a look(if I dribble in your engine bay I will clean it promise)I am in suffolk.

 

Again many thanks Dom

I'm looking at building one too mate, but i think one of the first things i would do is the gearbox with the LSD and the pistons, seems logical to do those things first to me, you'll need an LSD with 350hp, and you'll have to lower the compression also, so you may aswell do that properly with the pistons It will save you having to strip it down and rebuild it again, you may aswell do it right the first time and make sure your motor is going to be able to cope with all them extra ponies :)

Keep us updated on how you go 8)

All this is making my head spin a bit to be honest,I am hopefully going to meet up with a guy who is doing a twin turbo vr6 at the mo,and has done a lot of other vrt's in the past to have a good old chat about all things holy(that being vrt's esp vrtt's :D :notworthy: )

So hopefully I will have a better understanding of what needs to be done and will get things underway.

It will be done in 6 months tick tock it's on baby!

Ok Im going to be a lazy fooker and ask if anyone has good experience with Rotrex chargers other than B5VWC.

Contemplating one for my car but cannot find too much info on uk-mkivs and just scanned vwvortex however they seem more into the VF's.

Im not looking at any internal work, would just to get around 300bhp mark with torque to boot.
