well today i made up the exhaust flange to the turbo and welded it to the manifold. then i ripped off my old webber and exhaust setup to trial fit the setup on the engine in my car, shock horror there was no way it was goin to fit, then i realised that once the turbo was off the manifold the manifold would fit then whith a bit of a sqeeze the turbo goes on. is very close to strut tower, about 10 mm. i just hope my engine mounts dont flex coz it mite hit the tower. also realised that the bottom manifold bolts are goin to be very hard to tighten coz my exhaust bends are pointing on an angle towards each other. i may have to make a custom bent spanner to get em, no way a socket will fit. overall tho it looks stunning in the engine bay and there is plenty of room for a nice free flowing exhaust and dump. keep you all updated. probably doing the inlet part tomorrow! oh yea alittle voice in my head is telling me (injection) (injection)! see wat happens, hope i get big tax return

dont have any photos yet will try get some wen its finished. i was mostly trying to keep the inlet path as short as poss after the turbs. the inlet is going to be on slight angle tilting into ports so the only place fuel can pudle is in compressor housing. i no it made a huge difference on the turbo setup i had on a mini as to turbo size and wether the impella was spinning at idle which helped fuel from collecting in the comp housing and then going heaps rich for a bit after it was idling then driving. i have finished tacking the exhaust sections together and its looking good. very tight clearance tho, turbo very near the strut tower. inlets will just fit once ive ground the tubing away a bit and then may have to weld them together before i weld it to the manifold. hard to explain, try get some pics

Have you got any photos? could you post them if you have.
thanks

He means puddles of fuel forming in the inlet manifold. Thats why he is thinking to keep the manifold one so that the heat of the exhaust manifold goes into the inlet.

what???? why?????

i dot see what you mean?

To avoid puddles forming....Maybe u should use one plate for intake and exhaust. DOOOOO NOt cut the plate. This will mean that the intake manifold will warm up thus decreasing the likelyhood of fuel sticking to the inlet manifold.

Of course this will reduce the density of air entering the engine.....

hmmm sounds like suck through, why not blow??? that would be something diffrent

im using an a15 Heavy Duty clutch which is listed for vanettes, hasnt slipped on me but didnt get much use with the turbo system yet, unfamilia posted up the exact part numbers for it a little while ago, if you need the numbers you maybe able to search for em, it's a PBR kit, i have been getting em cheaply at $100 but dont expect to have to pay too much more than that, maybe upto 150

yea thanks for that guys, i may have to redesign my intake side of things or maybe get the grinder into action on a few of the exhaust bends so the inlet bends clear. i think i made it hard for myself because its all so close to the block because im trying to keep the fuel passage as short and uninterupted of bends and no spots fuel can puddle up in. Hey 1200rc what clutch are you running, i need an upgrade my stocker wont cope already slips slightly on standard a12. At he moment im just going to tack it all with the arc then mig it at work. The only reason i did four to two to one is because i had the bends to make it look tough and should be good because hopefully there may be some pulse effect like extractors, i dont no really just wanted to make soomething different to the proven log design i have done previously.

well, if there's little room then you're already ahead of yourself by using steampipe bends.

they have a much tighter radius than normal exhaust bend sections - so clearance will be easier to achieve...and if you're still running out of room then i suggest you go 4into1.

try to get the shortest amount pipe between your head and your turbo. this keeps the exhaust gasses hot and expanding which will aid in spool up time. obviously, the difference between a 30cm header and a 35cm header is going to be bugger-all but the difference between, say, a 20cm header and a 40cm header will be noticeable.

anyways, post up some pics . i'm always interested in different header designs and the advantages/disadvantages each design has.

just thinking why go 4-2-1?, seems like a lot of work for what?

just make em as short as possible and all collecting at the turbo should be easy enough
