Corrado vr6 turbo gt35 - pics and vids up, more to follow.......

[KIRAN VRT 10]

Well after owning a few rados I have finally decided to buy another and have a crack at a reasonable VR6T.

 

Just thought I would get a build thread going. May be helpful to someone in the future. I am aiming for 400WHP.

 

I'm parts hoarding at the moment but this weekend I am pulling the lump out.

 

So far I have

 

Holset HX40 turbo with v-band on exhaust housing and twin scroll

 

 

 

Spa Intake Mani

 

 

 

 

SPA External Waste Gate Exhaust Manifold

 

 

 

 

2mm Spacer

 

 

Prosport Gauges

 

 

 

ARP Rod Bolts

 

 

ARP HeadBolts - in this pic

 

 

Coil Pack, Cam Sensor, Trigger Wheel and also have Upper chain cover - not imaged

 

 

Anyway the parts list is growing and I will get pics of my rado up after I wash her this weekend

 

Also have a Megasquirt V3 on route

Nice, add LSD and traction control to the shopping list!!

Give Emu a shout, he had a lot of turbo hardware for sale !

Oh believe me mate lsd is deffo on the list of things to do and I'm hoping lag will be my traction control lol

cheers for that mate

right its been a little while since I've posted something so this is the latest news.

 

spa turbo mani + holset hx40 = fitting issues lol

 

basically the turbo was a touch to big as it fouled the clutch master, so i had to use my spare T04E turbo until I get everything running and then swap out for a gt35r

 

all

pics will follow tomorrow

 

I have an intercooler now, and also bought an apexi avcr boost controller, and 46mm external wastegate

 

pics of the build and the car itself, will be posted tomorrow

Mate, before you fit the Megasquirt, I'd have a word with Crazydave on here. He tried to get it working on his VR (and bear in mind he and Graham set up Midlands based DG Autotech VAG specialists) and struggled to ever get the car running right.

 

To my own cost I found that running an aftermarket ECU is a whole lot of hassle and hardwork. Now, if you're techy and will relish the opportunity to mess around with the settings and run everywhere with a laptop in the car, then fill your boots. Otherwise, at least make sure that the Megasquirt has got all the functionality that you'll need to control the engine properly bearing in mind what you're doing to it. Don't forget that an aftermarket ECU probably won't support a MAF or a number of the factory engine sensors, and that means you've less fail-safes and ways to control what's going (as I found out to my cost). The standard ECU can be chipped to support a turbo and will retain all the factory sensors and therefore off-boost, cold start and stock standard driveability when you're just running around. Even better, convert to OBD2 and enjoy an even smoother driving experience then get United Motorsports to chip the ECU for you. The money you'll spend is probably less than you'll spend buying the aftermarket ECU and getting it working even partially well.

 

Remember that VW spent millions of deutschmarks perfecting the standard Bosch ECU in all climates and weathers. As I have realised the more I've modified cars, blokes in sheds can seldom do better! That's fine and doesn't matter as long as you're willing to accept the compromises that modifying brings. So, I'd say be clear what it is you want the car to do and how much tinkering you're willing to get involved with ECU-wise; Finally, be clear that 400WHP is a huge amount of power in a Corrado. I would focus on the torque delivery rather than the BHP figure. (Remember: torque wins races!!)

Agree with that, my old car was OBDII and running a C2 genenric map and it ran perfectly over the 8000miles I did in the car.

hi guys,

 

cheers for the input on the ecu front.

 

my only issue is that how can an off the shelf map on a standard ecu be better than mapping on a mega squirt?

 

a mapper can do all the calculations in the world based on what mods you tell him you have, but with out physical testing its kinda pointless.

 

and i know you can get a custom map on a live rolling road on a standard ecu, but i want switchable map options, i want self learning with a wide band,i want to add more to the setup as i build and don't want to pay some crazy money for mapping because costs always start low but theres always a problem somewhere and you get shafted with the costs, at the end of the day I will try my best with mega squirt v3 and if all else fails then i mite have to think about other options.

 

you are all right about how much went into development of the ecu but once you go turbo this ecu is not rite for the car in my eyes.

 

I may be wrong but each to there own lol

[KIRAN VRT 10]

rite bit of an update,

 

i have fitted my arp rod bolts and checked my clearances and every thing is good in that department.

 

i have fitted my arp head studs

 

the head has been fully rebuilt and the block prepped

 

the head gaskets i bought turned out to be fibre so i returned them and bought the mk4 golf metal ones

 

it bloody started to rain so i didnt get to fit the head

 

but all systems go for tomorrow, weather permitting

 

i know i keep saying it but pics to follow, if it didnt rain today i wouldnt have an issue lol

 

either way i've got a week off work so i should get quite a bit done this week, hopefully.

 

also picked up an oil cooler and filter relocation kit

 

and a black edition avcr boost controller and a 46mm external wastegate

 

can't wait to fit everything !!!

Good man. You do what you want to do. Not everyone has bad experiences with standalones.

rite guys have taken a few pics before i trailer my car to the exhaust shop!!!

 

 

 

 

 

 

 

 

 

 

 

 

 

 

more on sunday after the exhaust is made

[Craig 0]

Looks good mate, not trying to sound like a complete numpty but where's the inlet on that inlet manifold?

[KIRAN VRT 10]

lol yea the inlet faces down towards the front engine mount direction

cheers mate, i fully agree and at the end of the day I wanted to build and map the car myself so why not!

[VAG-hag 0]

looking good!! nice clean car too..... what sunroof is that?? Looks raised if that makes sense?

 

Is it a custom exhaust you are going for?

[poll250 0]

Looks like a very good build! Good luck!

i was hoping some one could tell me what sunroof it is lol it came with the car, i guess it was the last owners take on a moon roof.

 

yea i'm off tomorrow to the exhaust shop, getting a custom 3" tig-welded and mandrel bent stainless steel exhaust straight through from turbo to backbox, 1 x flexi and the screamer for my waste gate, but unlike my last turbo car I'm not re-routing it lol

cheers mate, how are you finding your VR6T? hows the battle with traction? I noticed you put 17"s on yours. I'm thinking of buying some 8 pot brakes but I need a set of 17's to go over them. anychance you can recommend a good offset and width without rubbing the hell out of my tyre walls?

There is no chance of fitting 8pots under 17". Did try it and minimum are 18"

[VW_OwneR_85 1]

ha yea theres something not quite right with that sunroof, i realy like what you have done with the inter cooler/bumper, looks sweet.

[KIRAN VRT 10]

i thought the k-sport ones would? if not then i'll either go to brembo/porsche setup or k-sports's six pots

 

i was planning to use the porsche brembos from the carrera rear but i dont know if they are enough to stop me. oh btw whats the max size disc you could go on 17" wheels

don't worry about the sunroof - i will get round to sorting it lol

 

oh and thanks, i didn't want to do it at first but I think it works pretty well for looks and flow

Wow that exhaust will no doubt be a howler!! 8 pots may be snug under 17s mate..... I have 4 pots that fill the wheels pretty well. Saying that my Dads 6 pots fit nicely under 17s. Be pretty cool if you shoehorn them in!!

I know its going to be a bit loud but screw it you only live once and its the best thing for reducing my back pressure so why not lol

 

in all honesty i wanted to ideally buy some 16" schmidt th-lines and deck my rado but brakes suited for a VR6T will no way fit under 16's hence i though if i have to buy 17's then i will go for big brakes to fill them lol. what 4 pots you running mate?

[emu 0]

Well I never considered k-sport, they might fit, no idea. The biggest brakes you can fit under 17" are porsche cayenne 6 pot front calipers + golf mk4 r32 334mm front disc. Clearance is just 1mm on my rhzw1 wheels but you need 30mm spacers. I believe that flat wheels like some BBS cleat them better. There is more pictures in my build thread.

damn thats what i call tight lol that looks wkd mate, they must stop you dead in your tracks lol

 

i think i will be ok on my 8 pots then considering they use 330mm discs but i will deffo look into this more before using up yet another pay cheque lol

 

and 30mm spaces??? DAMN ...how wide was the front track after the spacers, any rubbing issues?

 

either way mate hats off to you
