Hay fellas

I'm starting to build my r34 gtt and i want to get about 260 to 300 kw at the rears.

So far I have a blitz return flow fmic

A pod filter

A 3 inch dump pipe to cat, And 4 inch cat back.

Is the 4inch cat back exhaust to big ?

Or should I buy a turbo to suit ?

On the to buy list is

Turbo

Injectors

Fuel pump

And ecu and tune

Am I missing something ?

Cheers

also easy to get massive kw,

just buy the usual shopping list tonns of fuel lots of over priced parts with a massive turbo and you will smash massive hp

also have a shit as all hell car to drive which will last for 3 months.

hard to make big kw, usable, reliable and well tuned.

Aim for 260 rather than 300 unless you have to have 300. Then get a Hypergear bolton, unless you're rich. Nistune ECU if you want to keep it as close to standard looking legal as possible, otherwise just about any aftermarket ECU will do the job (Hypergear will want to sell you an Adaptronic, which is OK, others here will tell you to go PowerFC, or Link or it's cousin, all of which are OK).

If you retain Nistune or PowerFC you'll need a Z32 AFM. Get some fuel system upgrades and a tune and you'll be gold.

Oh, and a clutch. Oh, and some better brakes. Oh, and thnik about making sure the dampers aren't dead, and the bushes. And so on.

Yep.

Clutch

Brakes

Suspension

Diff

Wider wheels and good tyres

That is roughly 6k just there and without it you 260rwkw car will be slower than a car with those mods and only 200rwkw

At 200rwkw my injectors were maxed and clutch started to slip.... So yes you certainly need to upgrade all the supporting items....

and at 360rwkw your clutch decided it wanted to be permanent part of your fly wheel.

I've read this 3 times and I'm still trying to work out what you were trying to communicate...

Lol yes this is correct....

Shows when building a decent GTT that overkill is never enough :)

better than the flywheel wanting to make close friends with your ankle... seen that too.

easy to make power, hard to make a good car

Kind of irrelevant for OP.... GTT is a tough base and a damn good car when built right

I will aim for 260 but if I can get more I won't complain :)

So a 4 inch cat back exhaust is over kill ?

I run a 3" system and I'm making 363kw, that being said the exhaust is choking the car a tad I reckon BUT 4" is not necessary.... If you go 3.5" then make sure it has big free flowing mufflers and none of this hotdog and cannon crap :)

if you already have it, just leave it on. it's overkill, but doesn't mena you need to go buy something smaller.

Good pick up, I didn't see that.... Yeah keep it if it's quiet and street able

E85 also masks some of that too.

If you tried it on pump you'd be unlikely to get there :)

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
