Jarno,

Lets try and help to get you up n running.

For your vacuum lines,  now you are proper single Turbo you really only need a vac line to the FPR and a 10mm feed to the servo.

For inter-cooler V mount is best, for 2 reasons, 1, each "radiator" gets its own clean flow of air and 2 the pipes going onto the inter-cooler will be shorter which helps turbo lag.

For the water rad you can lay it down at 15 to 20 degrees and it will work OK.


Make sure to fit an undertray with a few 50 mm holes underneath the rad. 

Back to tuning, forget water meth unless you want crazy boost as this is just more headaches for you, plus its worth knowing I dont even bother with this on the race car.

As for boost and power, just get the thing running and mapped to 0.9 or 1 bar of boost first, bigger power can come later.

To give you an idea, with the race car with the engine that's in the car, we started at 380bhp then as things got sorted, worked our way to 470bhp  :)       

Thank you sir for help. Much appreciated

All turbo and fpr lines are almost done. Just needs to be placed. Engines hoses gives me hard time tho

For v mount, im not sure do I have enough room for cooler. Turbos position make that area very narrow. And it doesent have piping and and aircone on it yet...

Choosing radiator is difficult too. Hopefully I can figure out that soon. I reckon I will get Koyo aftermarket rad for stock position. And big fan too..

Ill be getting one cooler from brother so I can do some measurements...

I will be putting some aluminium sheets to force air into cooling, no matter which system I choose to do

As for tuning, my engines brake inn will be really carefull. As for final tune, it depends engines charasteristics basically. Dont want to "force" it to make power if she dont want to. Its a cruiser afterall

Power is nothing without control. Weight is enemy of performance, handling and braking.

Started with 380 and now got 470???

 Damn, thats lot! Cause our turbos are basically same. In theory, I would have to push boost above 1,3bar to get that power... And you are running 1,3 bar too?

And yours is street ported right? I have basic BridgePort. I think I have bigger exhaust ports tho...

Yep, No Brap Street Port,  Huge primary's though  ;)   470 BHP @ 1 Bar, the last Dyno sheet is in my race car thread.

I have some sort of boost / misfire so once the cars up n running again its going on the Dyno again and hopefully I will come away this time the wrong side of 500  ;)
All the best Clive

Huge primarys? Umm, why? Mid range grunt? 

My secondarys are basic BP, only eyebrow is a bit wider. But port it self is basic stuff, from Pineapple template. Secondary is quite big too, but closing side is moved later. Hoped to smoot out transition from primary to secondary, even overlap might be bigger...

1 bar??? 470 @ 1bar is a lot from any streetport! Does your turbo still make power in higher revs or does it drop? Cause it means that your turbo is some weird hybrid

Mine is hybrid but its on its limits in 530 range. So I have no reason to rev my engine because of my turbo I reckon it would be able to make around 550 range at really high revs and like 1,6 bar boost tho, but thats really pushing that turbo too far, not to mention engine...

What coils you have? Friends here have notised that only good coils, that dont cost massive amount, is IGN1A that basiacally is same as AEM coils...

Good street port can do same as BP, but its much more difficult to do and measure in to correct position. Initialy I wanted to do that too, but then desided to do BP, didnt trust my self

Still waiting some parts to arrive...

All stock wiring is on. Some new hoses are in. Still much to do...

Finally got rid off stock exhaust. Was abit strugle. Started to do new exhaust. Downpipe is really close to intake. But then it clears nicely and I can use stock heat shields. Down pipes is lined up that I can put that big muffler to cats position.

Then I plan to cross it over to right side. I still have to figure out where to fit one extra muffler, cause two isnt enough I reckon. One big one goes to rear. And no, im not doing dual exhaust...
