i have notice one more thing with the car the idle is very high sits at about 900 to 1000 rpm, i tried to reset it to a lower figure but it still sits up at 900 to 1000 rpm could this be a connected problem?

Im only new to the scene and dont know too much, I have an r32 GTR, it also idles high, it is caused from a air leak in one of the vacum lines, so I would check them all carefully first. If you have the stock cat in it, you should be able to get 10-20 rwkw from fitting a high flow metal cat. I had the same problem in my GTR, when I got it and had it tuned, it really died off up top, I changed the cat and it made a huge difference, 15awkw. Yours is a rwd so might make abit more if you change it but you'll still fall short of 300rwkw, How good is the tuner you took it to? A mate of mine took his r33 to a tuner and got 213awkw@21 pound boost, he wasn't happy with the result, I took him to the boys at CRD (Croyden Racing development) they charge abit but do a fantastic job, they got him 260awkw on the same boost. The car was a jet when it left there. So tuning has alot to do with it. I would say do your research and find a good tuner, good luck!!

Skyhy,

I recently had mine tuned up and came across the same funny little dips. As we wound the boost up those dips got much worse and killed power.

Another thing noted was as the dips got worse a lot of unburnt fuel was floating around which instantly made me start thinking ignition.

At the same time the clutch began slipping 'slightly' which later got much worse.

I now have a good clutch in the car its amazing how more power wasn't getting to the back wheels.

I've got a few things that are to be sorted.

1. 450x280x90 FMIC with 2.25" inlet outlets.. Tad on the small side for the power So decent fmic

2. Spark plugs came out looking a tad hot. So NGK 7's in they go

3. I've been told to try NGK R5671A-7 as they position the spark in a slightly different position which prevents the spark being blown out. Apparently.

Fingers crossed the little dips disappear. :)

    • I’m doing some side developments on SR20det S13 engines, its one my hobby cars used it to compare flow capacity of some smaller size wheels. SR20det is one of another JDM legendary engines I'm sure there are plenty of SR enthusiasts on this forum, I will share results some common turbo configurations here. a quick run down of what the car is: Wide body 180sx Type X with black top engine (blue). It has: Stock bottom end Haltech 1500 ECU 5-0 motorsports trigger kit Kelford SR20DET Beehive Spring with Titanium Retainers Kelford Cams SR20DET S13 188-B 268/272 Cams G25-660 Turbocharger in T2 .64 rear housing internally gated ARP Head studs MLS head gasket 1000CC ID injectors Walbro 450L Fuel pump Front mount cooler kit JJR’s 3 inches turbo back exhaust (its too short for the 180sx it had to be extended) Pump 98 fuel Hub Dyno tune So far made 270rwkws at 22psi full boost by 4500RPM. Engine is very knock limited hence a pretty bad looking top end. From previous experiences it seems like SR20dets are happier with bigger size turbine, some thing like a GT30 would make way better top end, but on same time response is lost. It won't be a problem with S15 VCT engines. I'll be testing alternative turbine housing, turbine wheel and possibly dump pipe options for extra flow to resolve the problem and of course E85 would resolve all the issues.            
    • Awesome writeup and details. Thanks for sharing the story so far. I can relate to parts of it with my previous car and some of the issues I had to deal with.
    • Wow the colour matched hard top completely transforms the car. Are there any nice front lip options for the car or is that off the table?
    • Generally yes but for some reason I've been ruthless this time around!  I might even need to do another tip run after the way I've finally been able to hit the delete button on shit I've stepped over, stepped around and tripped over for the past 10 years!
