Furb that is sexy.

 

I am toying with the idea of using the same IC. it mounts very nicely inforont of the rad.

 

yeah it fits great and the way the end tanks come out its perfect. its also huge on 100+ degree days iv never seen ait higher then 40C

 

we get a lot of those 100+ days here. I'd like to do that mostly for the "non-boost" driving. My AI system alone works better than any intercooler... But in the summer, out of boost, the temps climb here.

I like the idea of having a little insurance if something went wrong with the AI, but the intercooler will actually hurt my current AITs. My pre compressor jet will be useless if that mixture then has to go through a physical intercooler... That is what I suspect at least.

 

It won't be useless, it'll have the effect of not letting the air temp rise as much through the intercooler as if you didn't have it.

Intercoolers are just temperature percentage modifiers. Cooler air in means cooler air out, even if the intercooler acts to heat the air up.

 

i will do some tests once I get the intercooler, but through the tests I've done already, the pre-compressor jet is the one that effects the AITs the best. The Post-Compressor jet is more for knock deterrent... that's why it's a larger jet.

What I am expecting is that the awesome drop I'm seeing in AITs will be neutralized by the intercooler. And I will only see a moderate drop in AITs.

I am curious to see the difference between an intercooler with the pre-comp jet and an intercooler without the pre-comp jet.

 

What you're expecting should pretty much be on the money.

 

sucks too, I am so proud of my non-IC AITs...

 

Im am doing this too. I just orderd my spacer last night! But i do have some questions..
How do i rewire my s4 T2 harness to work with the fd tps?

 

I am missing the connector for the tps . Can i make my own or do i have to find the conector?

 

ummm where did u find a s4 adaptor? no one makes them. To hook it up ull have to search for the wiring, its simple. ull also have get a FD tps connector, along with mocking up a custum way to allow the mechanical omp to work, ull have to shorten the oil fill tube and modify the fd upper mounting holes

 

There is a guy in greece selling the s5lim to s6 uim adapter kit all day long! He even sent me a pic of where and how much material has to be added for the studs to work.

 

yes but if you read the description says -only for s5- because the s4 has different ports....

do you have s4 or s5 lim?

 

Okay so while I am waiting for the spacer to arrive I am trying to figure out the FD UIM vacuum system. I took some pics so hopefully you guys can tell me if I am on the right track.





These three nipples go right into the intake runners so these should all get boost/vacuum right? Okay for boost gauge/controller or BOV vac sources?





A) Is this the air intake temperature sensor? How do I hook it up to my harness?
1)vacuum???
2)vacuum???
3)vacuum???
4)vacuum???



5)Pressure Sensor Vac Line
6)vacuum???
7)vacuum???
8)solenoid???
9)solenoid???
10)For brake booster?
11)Double Throttle - can I still use this?

I just need to know which nipples see vacuum and which see vacuum and boost so I can hook up the following items:


Boost Gauge
Boost Controller
BOV
Pressure Sensor
Oil Injector Spider
Fuel Injector Bleeds
Purge Control Valve

 

pic one yes vac nipples
A. yes ait sensor
1.vac
2. probly for the brake booster idk i blocked it off and used the large one on the top pic
3. vac
4. vac
5. vac
6.vac
7. vac
8. BAC i dont use
9. IAC? mines blocked off
10. i think is part of 9
11. i removed

thats at least how mines set up

 

Thank you very much sir. I do appreciate it.

 

most of those vac lines i do have blocked of tho

 

Right, I just need vacuum for a for things.

is there anyway to retain the double throttle system? or do you need a specific FD solenoid and ecu for it to work?

 

idk i just removed it along with anything else that complicates things lol

 

Alright, well thanks again for the info.

I just looked up the TPS rewire info, does this look right?

When looking directly at the FD TPS (when the push tab release is up), there are 4 pins.
1 - Ground
2 - Signal (Narrow range)
3 - (+5V)
4 - Signal (Full range)


Series 4 TPS Wiring---Series 6 TPS Wiring---------Series 6 TPS pin

Orange (+5V)---------BR/W - 5V+------------------3 - (+5V)
Green/Red Signal-----G/R - Narrow Range TPS---2 - Signal (Narrow range)
Black/Red Ground-----BR/B - Ground-------------- 1 - Ground
-------------------------- B/G - Full Range TPS-------4 - Not Used


I don't have the FD TPS connector though.

 

I cleaned up the UIU today, removed the double throttle valves and all the useless solenoids and crud, even ground off a few pieces of brackets to smooth it out a bit.

 

NJ what adapter are you using to bolt it to the s4 lim? and does the TB elbow clear the ps pump?

 

I'm using a S5 LIM and an adapter from ebay. I don't have power steering.

 

did you match the ports on the s5 lim to your s4 block?

 

No I didn't touch the ports on the LIM.
