FMIC And Elbows
Hiya chaps
just bought a FMIC and piping for my FC ( 1990 UK TII )
its come off a FC so i know that it will fit , but its been made to fit with the stock elbow - so it does a U turn out of the back of the engine
i can remember reading somewhere that you can use either the FC EGI elbow , or a stock FD elbow - but i cant remember which one ??
i have search on here for about 30 mins and cant find what i wanted - so its just as easy to ask !!
i know that you can get a "hat" for the TII - but im doing the FC on the cheap - so dont want to be throwing money at it if i can get around the problem
im sure that i read it on here that a guy used to race a FC with a FMIC and use a elbow and it would handle 20psi all day long - like i said - cant remeber if it was a EGI or FD one ( was DEFO platic though )
any ideas on this ??

think this is the thread
is this a straight swap or do you need to do more stuff ??
not sure i like the idea of changing the oil fill tube though

so the u-turn out the stock throttle body is fine ??
if thats the case then i might install as it is
and 1.1 bar is more than im hoping to run - im happy with 11psi to be honest - just wanna drop the temps
Thanks for the reply though

Personally I'd never use the stock TB entry with a FMIC even if it was part of a kit. It just seems like such a nasty compromise when you've gone to all that cost and/or effort.

humm i suppose its not the easiest thing to test if the U turn does make a difference
not sure what to do to be honest
might just fit the thing when i have chance - odds are - its better than the TMIC !!

I've got an Evo 4 intercooler that I tried to fit, but it was going to require more hacking than I'm happy with.

Again, I was stating what I had read in Maximum Boost, and he didnt provide a whole lot of scientific evidence for or against tight radius bends from what I recall. I was just curious if you had some other information. Why do you take it personally when I ask you for sources for your facts?
