Ouch!!!!
I would spend the money for a good turbo like Garrett, Precision or Borg Warner. I would not risk putting a Chinese turbo on that engine. With a 2056cc a GT2871RS would work great or a GT3071 with a. 63 AR. They don't need to be ball bearing, a standard bearing will spool plenty fast enough so you can save some money there.

Very nice!
Awesome welding/fabrication!

Which front end did you go for?

Thanks guys. Rolling road booked for 19th June so I’ll post back with some figures
I went with the red9 set up Ricola. I know it’s not perfect, I know it has its flaws but this is essentially a road car and does what I need it to. I’ve been through several steering boxes now and I’ve not been happy with any of them so a nice steering rack and a comfortable ride is what I was after and exactly what the kit gives me.

Well a lot happened between my initial Rolling road but long story short my engine got run up with my dry sump tank tap turned off (not by me!) anyway after engine rebuild and turbo rebuild we finally got some decent dyno time. The results were ok! 231hp at 6000 at 18psi. It was great fun to drive but as you can see in the graph it all came in very late (turbo too big). It also didnt take long to kill it, I dropped a valve seat after a few weeks of driving :( One thing I learned is that boost is addictive and there arent too many cars that can beat a beetle wtih that sort of power - BMW m4 couldnt make ground on me).

Anyways, my engine builder informs me that the valve seats were put in too tight and caused the ally to rupture and squeeze out the seat, So im now shopping for a pair of heads. Currently in talks with FAT performance.

Ive also had my turbo rebuilt with a much smaller exhaust housing (55 AR down to 38AR). Ive swapped out my coil, changed for a turbo smart waste gate and I have some other small changes Im making and hoping to get back on the rolling road before the spring!

231 hp at 18 psi with such a combo is a little disappointing tbh?
Or very very conservatively tuned?
There is surely room for improvement! ;-)

I agree wally, something was amiss, I do wonder if I had valve issues before hand. I was hoping to make 230 sub 1 bar. Let’s hope the changes and new heads help out.

Hi

Nice work, I'm not sure how you have routed your lines on the intercooler but experts have told me to put the cooled liquid into the throttle body end of intercooler. I'm using a frozenboost.com reservoir which has a big mouth that you fill with ice to really get the intake temps down for drags etc. the reservoir is also good for getting air out of the system.

It didn’t take long.....I killed it! I *think* it was mapped with a slight leak on the MAP sensor. The hose popped off and I pushed it all the way on. The ECU then kept reading overboost and IGN cutting. Kept dropping the duty cycle on the boost controller but I obviously spent too much time dropping small increments, over heated the heads and dropped a valve seat!

Anyway this gave me the opportunity to make a few changes. New heads (went a size smaller on inlet valves to leave more meat between the valves. Turns out my CR was super low and were now up at 8:1. I’ve also had the exhaust housing and turbine changed much smaller. Combine the upped CR and smaller exhaust housing I should see better numbers off boost and much faster spooling. All in all I’m hoping for much nicer driveability and similar numbers at lower boost. Going to the rolling road on Monday so we’ll see. Will map to 1 bar and see where we are at. Been looking into water/meth injection, anyone else running this? For relatively little cost it seems a good way to help limit heat which I guess is the big killer of boosted aircooled motors.

VERY nice car and stance!
Runs very smoothly as well. Pity about the troubles, but nice recovery!

Everything above 0,5bar boost or so (imho), you'd want some sort of intercooling. Water-meth is very efficient in doing so. I run Aquamist in the past and just received their newest version, but haven't installed it yet.
