944 Turbo Newbie checking In.

Welcome Pete. IMHO you would be better off with the standard air box as any HP gains from KNNs and the like are nullified by sucking in hot engine bay air. First tuning step is a dual port wastegate and manual boost controller with appropriate chips. Can be obtained for less than 500 quid and will benefit you by 50-70 HP. Best bang for buck you can get for a start and can be fitted easily without any further modifications to the engine. I personnaly would recomend the Tial as it is a fantastic sexy piece of kit. Lynsey ones are reworks of factory wastegates that can in my opinion be a bit fragile in the first place. Hence the reason mine got changed.

Someone on Northloop said that instead of the performance air filter drawing in lots of hot air from behind the radiator, i would be much better off with the original air box set up. Any other suggestions?

That would be me.. []

Hello!

Congrats on your purchase!

I'm with Rob about the air filter. I have one fitted to my Lux and i really don't think it makes a huge difference. It does sound good though!

My 2.7 had a K & N - first thing I changed!

This car already as the upgraded chips, dual port waste gate and manual boost controller, and is (presumably) running at about 300 bhp. I assume next steps would be uprated MAF and bigger turbo. 400 bhp here we come.

Not sure of your geographical location Pete, but, if you are in absolutely no rush whatsoever and positively enjoy delay after delay after delay, you could try taking the car back to Jon at JMG for this work. Though he's not the fastest, he makes the fastest.

Already done - from the advert
"Jon Mitchell performance upgrade including 9XX chip, Dual Port Wastegate, Manual Boost Controller "

AFAIK, the JMG wastegates are TIALS

JMG

sounds like they may not be completely operational at the moment - but having said that, they really do know their stuff.

I would stick at 300hp - getting much more becomes very expensive. Reliable 300hp, good cooling - oil, water, intercooler and you're well set

Electronic boost control will give you a flatter boost 'curve' which will gain a few horses, MAf will make it more drivable and there might be some small gains in power/torque, new turbo can create more high end power - even with electronic boost control the boost will drop at high rpms, and with more modern turbo technology potentially less lag,

Wot everyone else has said about various upgrades ! You can get a K&N filter to fit inside the original airbox, I woudl certainly suggest to doing that.

Other upgrade emporiums are available who would claim the same thing (outside the 3.2 conversion) but with a rather quicker turnaround time too !

Thanks Ewan,edh and everyone else with your obviously, well informed comments. They have been a great help! I am defo thinking along the lines of the airbox with a K and N panel filter and possibly a bigger turbo, injectors and uprated fuel pump to start with. Of course, i will have to see how the finances go but, i'm looking forward to getting this one started. I will post pics at the weekend. I have got to sign off for now as i have some drawings to do some costings on for a large heating system in Lewes. That means bed for me at around 1am, then up at six! Aint life a b1tch!!

I'd suggest you run it as is for a while, use your money fixing the stuff that you are bound to break (track miles take their toll...)

Then
Good brakes - PF97 pads are my favourites, with decent cooling (968 ducts if you have the right wishbones)
Good suspension - not sure what is on your car but old M030 won't be optimum - Gaz (EMC spec) or KW v3 are the places to start
Lighten - Lose 100kg if you can, will certainly make a difference (lightweight 17's would be a good move as well)
For a track car I would put in another oil cooler, bigger intercooler (you will get heat soak on a small intercooler if you run long sessions / high boost on hot days)

After that, if 300hp isn't enough, that's when it can get expensive
if you're going to spend some big money on power hikes, I would definitely look at MAF or MAP setups - allowing you to swap turbos, tweak boost etc.. without needing a remap. (Would also enable you to relocate a cone filter somewhere sensible)
Vitesse (US vendor) is expensive but works well.
Barks944 on here is building has an ECU (DME) project that looks really good - would be worth checking out.
SPS (Simon Peckham) builds some very interesting hybrid turbos..

Of course it all depends on your budget - whatever you have, I bet we can spend it for you []

 

[Diver944]

I've got to agree with Ed. I went the other way and had the huge JMG 3.2L engine first because my old engine died, and then on the 3rd trackday after that my brakes failed [].

Get the car up to fine standard fettle first, then by all means get a chip and a boost enhancer for circa 290bhp at a couple of hundred quid. After that the brakes will need a bit of looking at if you are heavy on trackdays. Gaz Gold or KW shocks are the current forums choice for track use, with the Gaz being cheaper but also harser on the road.

After that the sky is the limit ££££££ []

When I see owners talking about uprating the power on their new old car when they've just got it I wonder why they didn't buy something faster to start with, not trying to be a killjoy but it has 180k on it and it seems to be running fine, there could be trouble ahead.

Nothing that a total rebuild could'nt sort out []!! Here come the photo's...(hopefuly).

It keeps saying "file too large"? I will have to try again later as i have got to get ready to go to Millwall now. I managed to post them ok on Northloop, so i wonder whats happened here?

For what its worth I have measured the difference at the intake on a non turbo and yes in traffic you will see higher temps with a cone type filter but at speed the temperature drops to around ambient and the same as the standard airbox.
I suspect it may be a bit warmer on a turbo due to the extra plumbing, heat from the turbo and the intercooler, but I cant do back to back comparisons as the standard air box wont fit my current car

 

[Ex Skyline]

Ok, i have left several posts on here since yesterday morning and now they have just sort of vanished into thin air? Very confusing to say the least! Also, i cant seem to get my piccys up on here, keeps coming up as "file too large". What does that mean? Anyone got any ideas on how i can get them on here coz i havent got a clue! If any of you go on Northloop.co.uk i have managed to post them on there under "members cars and projects". Perhaps the more computer literate whizz kids amongst you could nick them from there and get them on here somehow! Whadya reckon guys? They are not the best photos in the world and, David Bailey i aint but, they show what a nice little car he is, especially as he is now all valeted up. Regards.

Hi Pete, the easiest way is to upload them to Photobucket and paste the links into the dialogue box that appears when you click the picture icon above
