Project Avant+

[Ross]

Anyone who has read my 'project 400' thread will know that the Coupe came to a sad end. Fortunately, many parts of it have lived on in other people's 3Bs but I have kept the engine for myself. Here are the parts i have:

1995 Avant with full RS2 exterior/interior/suspension mods inc. 996's up front.
3B engine complete, rebuilt with SPM rods. 7A ex. cam + uprated clutch.
ABY engine complete, 120k miles
Bosch 044 Fuel Pump
3" Downpipe
RS2 IC
RS2 IM
RS2 EM (cracked)
RS2 Airbox
GT3071R turbo
630cc "Audiman's Special" Injectors
Paul Nugent's 300mm rear brake upgrade


The plan is to replace the RS2 EM with a new, ceramic coated item and fit the GT3071. We aim to mod the Airbox so it can be kept. MAF will be moved to pressure side to avoid any stalling issues from last time.

The downpipe will be mated to the 3" cat-back system already fitted, RS2 IM and IC retained, and the ABY head will be fitted to the 3B block with a dual-layer HG (do not want to remove pistons for skimming).

The 7A cam will be swapped to the ABY head, which will be rebuilt with an 034 oversize valve set before fitment with ARP head bolts. I also intend to fit new ABY oil pump, RS2 water pump + AC compressor (currently not working). I am investigating fitment of a larger oil cooler as well.

Work will be starting in a week's time, I'll post some pics and updates as it moves on. The original engine dyno'd 428bhp; my target here is 420bhp with the new engine, but with slight stealth-refinements (such as the dual-box exhaust).

Good luck Ross, it was a sad to hear about your coupe, but your 'project 400' thread has been a brilliant aid to me in my own project. I'm glad you got what you needed from the insuarance company. I am also impressed that you are going through it all a again. Fairplay

[topsparky]

good luck mate
saw your car at corey's place on saturday
looks a sweet car

[Al Wyn]

Sounds good start cracking the whip Coreys way and wow them at inters

[Jamo]

Good on you Ross, hope it's running for inters! *grumble*

Should hit 450 bhp this time round I reckon.

why 420 and not 428 bhp ? is the extra 8 bhp too much for you ?

[4WheelDrifter]

Why the new oil pump Ross? Is your old one on the way out?

[Ross]

ok so 430 would be nice... I'm figuring with an extra silencer and a race cat in the exhaust, I'll probably lose a few horses. So I'm setting my goals low to avoid dissapointment

If it does 450, I'll be a happy camper

@Stu, when would you replace an oil pump? Just figured the ABY one has 120k miles, and I wanna use the ABY pump rather than a 3B item. I guess if hte oil pump looks good it could be re-used, was just gonna have it done outta precaution really.

[4WheelDrifter]

There's not really much that can go wrong with the oil pump, it's only two gears in an alloy housing. I've got a 120k miler to go in mine. Although I'll check the 180k'er to see how it looks. New oil pumps are £££.

[Corey]

The conversation with Ross regarding the oil pump was that the one on the ABY will be removed and inspected but for total peace of mind a new one would be fitted as a precaution, there is an awful lot that can go wrong with them but thats for another thread.
Why sacrifice a 450bhp £5k engine for a £250 component?

[4WheelDrifter]

If Ross isn't having oil pressure problems now, then I can't see it being too much of a problem.

[Jon441cc]

Err, if your going to be keeping the power between 400 and 430hp why go with oversized valves when you achieved 428 with your current set up

[Corey]

You may not see the pump as a problem, I do.

more restrictive exhaust (he wants a bit of comfort) being one of the many reasons Ross has chosen the list of parts but the main reason is that while he is aiming for the same bhp, the CR is being dropped and a few tweaks made along the way to aim a little higher.
I am sure Ross will explain

[Jon441cc]

He's aimed higher already going with the Avant this time round
