Looking damn good. Need to get a adaptor like that made up too. For the turbo inlet

:D Thanks Riekert. Yea its easy to make, just need some alluminium plate offcuts, a 63mm alluminium offcut pipe, an angle grinder, and a drill and hole saw, and some time, unfortunately i dont have the luxury of the equipment to weld alluminium so i had to pay a company R100 to weld it up, but hey in the end it costed me R120 to make that adapter, polishing the whole turbo in total came to R140 with that adapter.

heres some pics of how close the wastegate will sit to the compressor housing, theres quite a decent gap. I dont think itl be too bad, ive seen worse, with some heat shields and heat wrap i think itl be fine, i was kind of regretting not putting it on the exhaust housing side but ag itl be fine im sure.

Right heres some updates:

welded up the manifold finished and then had the main flange skimmed:

Image

then i ported the ports with a die grinder to match the gaskets and ensure smoth flow:

Image

did this aswell with the T2 flange on the merge collector but forgot to take pics...

then i sprayed the manifold with hi-heat black paint, its only rated up to 600deg celcius, but ive had good luck with it in the past, it lasted over a year on a friends manifold i sprayed, lost its color and went a dull grey but still protected from rust:

Image

Image

Image

Image

Image

Image

Image

then i wrapped it up in some nice black ceramic heat wrap, wasnt sure whether to do it as ive heard it can cause the welds to weaken and crack over time, but i needed to do it as my clearances are so close under the hood:

Image

Image

Image

Image

Image

then after all of that i was able to finally start putting things together :D

Image

Image

Image

Image

Image

Image

Image

looking quite good so far, still need to make an adaptor feed for my power steering, still need to finishd downpipe and water lines to turbo, but i have driven the car, just with a mockup water line from block back to intake line, and my airflow meter and filter held in temporarily and an old boost pipe connected, and the car is driving awsome :D boost kicks in a lil late due to my manifold design i think, as the runners are so long and fairly large inside diameter for an 1.8l, but when the turbo reaches full boost it really goes well, my wastegate spring is at 0.5, so i ran direct source pressure from my compressor housing to wastegate with top nipple venting to atmosphere and the car didnt boost over 0.6 and held 0.6 fully, reaches full boost at around 3500, and holds full boost right till 6000rpm (didnt want to take it higher) :lol: big improvement compared to my old T25 that would start to slack after 4000rpm. everything is healthy and im quite amped to have it done. although there is alot of work still to be done, ive got my FMIC to install and boost pipes and electric fans and battery relocation, but so long il drive it low boost with sidemount as ive been without the car for 5months now and i want to just drive it for a while before it needs to stand for more work.

Il attach a video of the drive i took. i put my standard bottom mount cast iron downpipe on and drove it without the bonnet so the downpipe faced up towards the sky, was pretty loud haha, midnight drive throught the neighbourhood tearing S#%t up :lol:

Small update, did my boost pipe from turbo outlet, and did the inlet for airflow meter and filter, also you can see how i used the standard downpipe in the air to just drive the car around the block without burning my firewall. When get around to installing my FMIC then i can just connect my 63mm boost pipes to that 63mm coming out so no parts wasted for the small time i will be driving it side mount.

Must still do water lines and downpipe and power steering feed line adaptor, drove it with power steering belt off just to test so long.

its all coming together :D
