Ok Chip where are you

Now i need some info for my brother in-law he has a 03 plate Astra GSI Turbo


Right he wants to put a Dump Valve on it and wants to uprate the intercooler so he can up the boosted to so he can run about 260bhp ish i belive
Can anyone help with any of these Questions

I'll get some pic up in abit of the engine bay Ps this is the eco tec engine not a red top

Dump valve is easy enough, just need to block off the internal one (WHY THOUGH!)

For intercoolers, there are kits available but they are mega money, just buy any old intercooler off ebay (cossie 4wd one?) and use that with some smaco hoses.

Give Chris a ring at REGAL autosport @ southhamton.
They do all the EDS tuning goodies ( chips, front mounted coolers, power pipes, DV's, basically everything! )
I used to own a 175 bhp valver nova and a 300BHP Mk4 Astra Turbo ( Calibra Turbo engine ) and Chris sorted almost everything for me!

Yep migweb is the place for vauxhalls

Ok im not sure WHY he wants one he just said he wants to put one on it ?????????
How and where is the internal one and how do you block it off
Im guessing the dump valve T piece goes in the hose coming from the intercooler to the throtal body (sp) But where does the pipe T into that comes off the top of the DV

As for the inter cooler He's not kine on cutting the pannels ect
So would the 4x4 cossie IC be ok then
Ps whot the web addy you go on migweb or some thing ???

Oranoco, chip-3door, bigpower,
CheeRS I'll pass it on to him
Chip he did say that he sore a uprated IC on ebay or some where like that and he said he nearly fell off the chair when he sore the price
Ps whot turbo is on it T2 or sum thing looks very small and also is it a ood idea to adjust the actorater (sp) a bit and if its ok to do it how much should i do it by

Oranoco

DIY tinkering is never a great idea. It'll only end in tears, expensive ones at that

He'll need different software before you start adjusting it or it will just boost cut on you.

There should be a vacuum pipe already in the throttle body that you can T into that will operate the dump valve

Its a KKK turbo

TBH i dont know a massive about about the Z20LET series of engine, its a bit modern for me, im more a C20LET guy, so posting on migweb is a good idea as i dont know the exact details of what chips are best etc.

cossie 4wd cooler is fine in terms of cooling performance, but you will need to make sure you can fit it somewhere physically, which i havent ever tried on that car obviously as ive not had one.

Alan s1

Very TRUE
Also he wants a boost gauge as well where would you link that into

Oranoco

Same pipe the DV control pipe will T into.

If you want some serious advice, what i would recomend he does, is save up a bit, then get a dirty great custom made cooler as big as he can fit, then go to MAD for autronic on it.

Thats the proper way forward, he'd be looking at 300bhp ish from the standard engine if he did that (and slap a set of greens in it)

Ok thanks chip I'll put a post up on there for him Also i relised he would have to fine away of fitting it
