intercooler pipe work

[SCHWARTZ]

i have asked this before but a few things have changed and i couldnt find the old thread to continue that.
I will be buying an intercooler which has 3" inlet and outlet. Is it best to run 3" pipe work all the way with a big enlarger/reducer from the turbo to the pipe?
Or to run a 2.5" pipe work with enlarger/reducers to the intercooler and the throttle body?
would a 3" pipe run cause any noticeable lag over the 2.5" run or would it keep the air colder and allow the cooler to perform better?

[SCHWARTZ]

this will be used with the b18ft and a t2/25 turbo (to be upgraded when i can afford) running 18psi and no dump valve!

[Markey Mark (BD)]

You won't notice much difference mate, what size is the throttle body your using?

[SCHWARTZ]

the one from the b18ep.

[SCHWARTZ]

it dosnt really matter now tho fella as the cooler i was looking at just wont fit. I liked the fact that the inlet and outlet were on the same side which would keep the pipe runs nice and short. i will keep looking but for a smaller cooler with both inlets on the same side. probably just use the gtt one for now.

[Markey Mark (BD)]

I doubt thats 3" then so i would go for the smaller 2 1/2" pipework mate.

You got pic of the cooler mate?

http://cgi.ebay.co.uk/ws/eBayISAPI.d...ht_1217wt_1026 wanted to try and make it fit but i really dont need it just wanted it.

[Markey Mark (BD)]

How comes it didn't fit, was it hitting on something or pipework catching the frame?

[SCHWARTZ]

dont think it will fit behind the bumper. Cross member would have to be cut out, 790mm end to end and 300mm high, think it will be a lot bigger than i need and would take ages to fill. Wouldnt it?. Also i dont want anything obstructing the rad well as little as poss any way.

[SCHWARTZ]

i havnt bought the cooler. It would be easier to check if i had, but just going by a rough measure up.

[djinuk]

I fitted this, no probs with temps so far, i did however cut the cross member out and now im thinking if i should of .

[SCHWARTZ]

thats hows its done. Will you be putting a (modified) cross member back in? Surley its needed to keep everything stiff.

[djinuk]

well this is the question , im not sure yet, i believe there is a few 5s on here running around with out one, that dont appear to have a problem, but i will probably see what i can do.

Smaller item for you

[SCHWARTZ]

cheers phill that may do it. Il have a measure up.

[SCHWARTZ]

bought a cooler (in phills link) needed slight cutting of the cross member but its all in just needs piping up.

[James5]

Looking good Gary, can't believe you still haven't had the wing, bumper and grill painted that was over 2 years ago when i last saw your 5

[SCHWARTZ]

may get it painted one day. looks aint really my thing want to get it running well first then get it all painted and looking pretty.

[philg]

what size was it?

I bought the 650x230 and it just wont fit so have gone for the smaller 180, i can not bare to start cutting my car after painting it.

[SCHWARTZ]

yer its the 650x230 all i cut off was the top part off the crossmember and those little triangle type bits on the crossmember and a little of the passenger headlight bucket. All sits in quite neatly and leaves enough room for pipe runs. bumper didnt require any cutting nor the grille and the rad sits in its usual place.

[SCHWARTZ]

yer i wouldnt have wanted to cut up your car either. happily my grinder cut through the rust nicely the smaller cooler should fit fine without cutting though

[philg]

good stuff

[devilish dave]

good stuff

i'll cut it for ya you big girl, phil

i've decided to take the b18ft out the 5 and fit it in a clio valver just so i can still look after ya

[TrixNFlix]

[SCHWARTZ]
