upgrade GTA

hello,
sorry for bad language, but I from belgium.


I am want information to over boost PRV motor from Alpine GTA V6 turbo 87'.

what do you think about air/water intercooling system. (sorry for bad thecnical used)

One of my friends is the boss of a company that repairs the engine and cylinder heads for the sports car.
I can then use the machines as I want.

use the yoke of a 3 liter engine of a Citroen XM to increase engine?
Standard base engine venture?
Or what possible preparation to reach 280 / 300 hp engine for PRV?

I also want to improve braking. what are the fixtures possible with pieces of Renault and Peugeot (406 ,...)?

thanks you.

You will find the SEARCH facility on this web site to be a very usefull tool.

Search for Chargecooler (it is a water to air intercooler). YES, they work very well, go to www.chargecooler.co.uk for options. I have a 10 by 4 unit.

If you can wait a few months then you might well get some real answers on what is possible and works with custom GTA engine builds .I know there are a couple of engines being developed at the moment .
A good look through the web pages search will give plenty of theory but very little in the way of actual results .
I would start by making sure your engine wiring and sensors are all correct .Check all your fuel system and renew with new and uprated bits if required .
Many a std old GTA will not have the book quoted 200 bhp .You may well find you get a lot of that back just by servicing .
You will need aftermarket ECU as well or at the very least a chip .

I think it's pretty well agreed that the Z7U cannot be pushed past 260hp without different cams, but nobody over here has done a cam'd Z7U as far as I know.

For the figures you're looking for, the approach I'd take, given the cost, would be to buy a Volvo B280E engine, then take the cams and crankshaft from it to fit to your Z7U and have a set of pistons made so that you can create a 2849cc low compression Z7U with decent cams. You will need an aftermarket ECU too.

It's surprisingly more tricky to do a 3 litre engine - for a start, you'd need an A610 intake manifold.
