Hi All
I've been debating about posting this to the DeLorean forum because I guess there're a few out there who've "heard it all before" but here goes...
Through the time and experimentation that went in on the twin turbo DeLorean, I got to learn a particular aftermarket ECU that is known in the Renault Alpine community over here. It's particular ability to read a stock Renault 66/3 flywheel makes it the obvious choice to run a Renault EFI engine (like the TT DeLorean). Not long after getting the DeLorean running, I was approached by an Alpine owner who's had a tough time getting someone to set up his engine. It's probably the most well known Alpine GTA in the country, and here's why...
Three years ago, the owner decided to pension off the original 2458cc turbo engine and invest in a brand new 3 litre lump direct from Renault. To this end, he bought a Hartge tuned Renault Safrane BiTurbo crate engine. What arrived was the short block, and with the addition of an A610 intake manifold, all his original GTA stuff bolted right up. He also invested nearly £1000 in a custom made T38 Turbo - T3 turbine, T4 compressor. The intercooler was jacketed and water piped to a pre-rad at the front. And then got stuck wien it came to the ECU. That's when I got the call.
Last week with a very basic map based on the TT DeLorean. we were able to take the car out on the road for the first time. The GTA has the same weight, the same clutch and the same ratios until 4th (4th and 5th are fractionally taller) as the DeLorean. Wow! I came back from the first run thinking "If we can get any DeLorean to go like that, it'll blow your socks off!". A few days later we got to the rolling road for a proper mapping session. It was running only 8psi of boost and generating 160hp at the wheels. Easy to forget how utterly torquey these 3 litre engines are!!!
After a few hours of work, a blown turbo pipe and serious trouble getting the car to stop spinning its wheels (275/45-17 racing slicks no less), we were running off the top of the scale at 240hp at the wheels at 5000rpm at 15psi of boost. The rest had to be done on the road and some 20% was gained in the 5000-6000 rpm. The Renault boys reckon on 60hp loss in the transmission, so we were already over the 300 barrier on the rollers. 20% on top of that??? AND only at a bar of boost?

What can I say? Out on the road, I was in my element.... I've driven Marc's Nissan engined DeLorean and I'm sorry to say mate that it wouldn't have a prayer against this GTA. The owner also has an R32 Skyline modified for 400hp, and even he said the GTA felt faster. The PRV was tuned for torque and the way it pulls through the gears is more than enough to implant a surgical smile on your face.
I've got two of these engines on the shelf just waiting for the money to be put into installing one in a DeLorean. Nearly there!

does anyone know if the Volvo 260 prv has the same cam shafts as the delorean?? I have managed to aquire a set of volvo 260 cylinder heads and what i would like to do is refurb them and get the camshafts modified to performance cams, if someone could advise me because if I can I would like to keep the original delorean heads intact so i can just put these refurbished ones ( when i get round to doing them) straight on. many thanks, jason.

Radiator removal |

I'm cleaning up the front area and yes - I got off the front fascia, no problem, thanks for all suggestions earlier!!!
1. Now, I'm considering replacing the radiator - what is best, stock plastic or new brass radiator???
2. Does anyone know HOW to get the old radiator out?
It's a crowded area under the front, there are lots of parts.
I can see the fan cowl.
3. Does the fan cowl have to come out in order to get to the radiator?
Also, I thought I saw the radiator firsthand, but I think maybe what I'm looking at is part of the airconditioning system?
4. Is there a part of the AC system that are mounted in the same area (in front of?) the radiator?

A quick tip for anybody wanting something to clean the stainless but without the expense of 3M stainless polish, or the sticky residue left by baby oil....
Try WD40
I have been using it for sometime now and it leaves a nice even finish, doesn't attract insects, minimises finger prints and a tin goes a -long- way
