Too right! Give it a strong 1.5bar until i can sort some valve springs.
that rad looks a good bit of kit! coming on well mate, be good to see how much difference that makes with the bigger turbo too
Yeah i cant wait to find out how the new turbo is!
Abit more progress today.
First things first i forgot that id need new fans with the new radiator, rywire designed the mounting system around a fan thats only available in the USA. Naturally i didnt want to pay $100 plus shipping and taxes for a pair of rad fans.
So i took a punt on a pair of universal jobbies at like £40 for the pair. Fits perfect!
Then thought id finish up wrapping the downpipe to get that off the list.
Then it was the radiator ducting, id already made templates for left and right of the rad so i got those cut out in some thin stainless steel sheet and welded them in along with blocking off the gaping hole at the bottom. (More "welding")
Then i used some duct tape as a seal for the blocking plates to the radiator.
Ive left the top of the rad open for now but i will sort something for it once ive decided the best/easiest/cleanest way of doing it.
Then it was time to fit the intercooler back on and make some air guides to stop the air hitting the rad/intercooler and moving either left or right around the car. I didnt get far but ive decided to go "gobstoppper" style with the intercooler and essentially make a scoop for it to grab more air. This is only the first piece
Will become more clear to everyone tomorrow, i also need to make a blocking plate between the chassis and the bottom of the intercooler to stop the air going through the cooler then escaping under the chassis.
So alots happened (might not look it but feels it lol) in the last 2 days.
I got to work on the rest of the air guide/ram plates for the intercooler and radiator.
Abit of cardboard templating
Chuffed with how these came out! As you can see my plan is to trap the air infront of the radiator so that it cannot escape around the car or get through any gaps etc. Im heinsight i should have gone larger with them so that they are flush with the front bumper. My "welding" seems to be improving alittle bit aswell. I dont feel ashamed to let people see these welds lol
Gave them a quick shot of matt black to keep them fresh and somewhat hidden. I decided to block the top of the rad with duct tape for now, i didnt want to weld more metal in on the slam panel and pull all the paint off of it, i see no issue with using the tape other than it might break and let the air out. Would prove im making good pressure infront of the rad though.....
Here is the only place i could think of to put the oil cooler, its such a tight squeeze in there! Not helping that the cooler is 25row, and that i couldnt really go infront of the intercooler. Hopefully it will work out ok there.
Next up was wrap the hotside boost pipe in cool tape, ive done this aswell as wrapping the downpipe because now the downpipe is 3" it comes pretty close to the boost pipe and i wanted to minimise heat transfer between the two.
Offered up the front bumper, knowing it was going to need some serious chopping to "fit"
As you can see not much left of it at all! I made the mouth of the bumper abit bigger in the hopes of hitting more radiator with unblocked airflow and obviously gave the oil cooler a hole to cool from.
Ran the new oil lines back to my inline thermostat
Thats about as far as ive have got.
Will re-attach my front lip and make sure that all fits fine tomorrow then its waiting game for turbo to arrive i think.
Turbo-men got to work on my turbo today, they said they couldnt use the antisurge housing that i currently have on my turbo because they need to take too much material away when fitting the larger compressor wheel.
This leaves me with a standard gt28 housing, if i start gettimg surge issues then i can possibly source a gtx2871r compressor cover. My issue with this is the inlet is 4" on that housing and tjat is likely to cause clearance issues with the bleed nipple on the clutch slave.
I also confirmed exactly which parts where going into the turbo and they are
Gtx30 71mm compressor wheel
Gtx30 60mm turbine wheel
So basically my turbo will be a gtx3071r crammed into a gtx28 frame.
Thats all the news i have so far. Hopefully have a turbo mid week!
Serious re-modelling of the front end there dude! Can't wait to see how efficient this is.
Bigger turbo = massive smiles!
What started as a simple fit new rad job has turned into a full on rebuild of the entire cooling package and front end!
Really getting somewhere now though, i must not forget i need to find a way to block airflow from going down behind the intercooler and under the chassis.
Yeah the turbo is basically 1 size up on the cold side and 2 sizes up on the hotside according to garretts current line up.
Exhaust flow shouldnt be a problem with this turbo, i suspect i was getting to the end of the old turbo and ive learnt now that hondas need a large turbo!
Picked up the turbo today!!
Probably going to need the gtx compressor housing if im going to hit the big numbers.
This current housing (chosen because it will defo fit in the space i have) has only a 3" intake, the gtx housing has a 4" one.
