Hey guys. N1GTR and I were in my car today and i noticed sometimes that my car was missing. It sounded and went exactly like it was when my plugs were fouled, I changed them and bingo back to its normal self. Now I changed plugs the other day and have only done 150-200 kms since. I put in BCPR9ES-8. Im starting to think that the 9's are a little cold for E85. I had the same plugs in when it was on 98 and it never had any issues what so ever. Should I drop back to a heat range 8? I gave it a little splat on the way home and it felt fine. So I suppose my question is what plugs do guys use on E85 with 400+rwkw on tap?

How much work have they done?

Ah Marko you found one! Nice work!! When you bringing her around? haha -5's and Steve. He has bought a set however they are not going on yet. Im tossing up the idea of throwing a set on -5's on mine.

HKS GT RS's are the HKS equiv.... well close enough to it. I have them on a 2.8 and there are times I wish I had the -5's on mine. I wouldnt recommend putting them on a stock engine....

I got a Tomei 2.8 with tolerences of 2 thou between piston and bore. 25 PSI 400 rwkw + and doesnt use a drop. What goes in is what comes out.

Stock if you can get them cheap.... IE NOT from Nissan AUS

Bump $500

Had a great arvo/night also. I too could have listen to Jim talk all day. Deffo be at the next one!

Mods if you feel you need to move this thread then do so.... I wasn't 100% sure where to put it. Ok. My car sounds like a busted arse at the moment and looks like I have cracked a set of Tomei manifolds... for the second time. This set is less then 2000 kms old. Yes you hear of guys running stainless manifolds and some of them crack but not everyone has this issue... and not after 2000kms! I have a set of stockers but I dont want to put them on without atleast match porting them... preferably extrude honing them. Does anyone know where I can get this done.... Does someone like Racepace sell modified manifolds off the shelf? I know one thing... I'm not putting another set of stainless ones on....

I had my stock coil packs start to break down over 20psi (370ish rwkw)....while using the Twin spark. Went and bought a new set of stock coils and all good. Personally in your case I would buy a new set of coils.... and if you still have issues then chuck a twin spark at it.

Ha! Send it to wherever via my joint....it might have some intimate time with a baseball bat!

Its going to be interesting the see just how bad the economy is when going for a 'spirited' drive. Will it be a case of the needle free falling without a parachute? Only time will tell!

Thats crap man. Chuck it in the bin and get an old dinosaur PFC! No issues

It might give that figure on the dyno but I can tell you now i reach fullboost on the road ALOT earlier then whatever it says on that sheet! It feels fine.... You have to remember a stock GTR makes what.... 180 or 200 kw at the wheels stock.... It might only feel like it has "not much" because 1000 RPM later your making almost double that! To drive around in traffic is no worries at all.

Get your TPS sorted Steve?

Another problem is the CAS. Both Steve and I have developed Crank Angle Sensor noise above a certain RPM.... So basically you cant be 100% accurate with the timing up in the rev range. I was warned about this before this tune and was hoping it wouldnt come up.... but it did. Now in all my years of scratching around on SAU and the pommie forum I have never seen a thread discussing this issue. Has anyone else come across this and if so why isnt it common knowledge!?!?! There is a fix... a balancer trigger... but thats expensive and to be honest I really cant be arsed........ thats what I said 2 years ago! haha

Nah mate second. at 8000 RPM with 4.111 diffs (stock) 1st = 87 2nd = 138 3rd = 190 4th = stock (1:1) 5th is shorter at 290 but i stuck with the stock gear which goes to 310

Ha. Spinning the rears at 140 in second (OS 5 speed) in the dry is hell fun! haha

Yeah the midrange is what I was hoping to really gain out of this. As we all know GTR's have sweet FA under 4K anyway (unless you have a dirty 30.... which one day I will have haha). Ash there are times which I had the 2530's hanging off the side of mine, Esp with the OS 5 speed sometimes you just cant carry that much speed into slow corners..... this is where a 6 speed would really shine! Get her onto a fast flowing track like Eastern Creek and thats where it would love it! But lets be honest... I aint changing turbo's. Effort, time and money. 600 HP road car is enough for most people yeah? lol

Yeah they have.... only had it a few months I think I was hoping around the mid 400's. As you can see the difference between 1.7 bar and 2.0 bar netted an extra 12 kw. Yavuz reckons its the exhaust housings and the exhaust choking it up a tad. Hmmmm i dunno Tomei Expreme.

Was a little bummed at the final figure to be honest. Its funny... My last tune on the same dyno before the ARC cooler went on was 370 rwkw on 98... and this time I didnt crack the 350 mark. Bit strange.... They have changed dyno's though.. maybe that has something to do with it. Either way it feels 461946129649% better on E85. The throttle response is amazing. It almost knows what your going to do before you do anything with your right foot!

Sorry for the late reply haha. I have a few graphs to show the difference between E85 and PULP 98. Same car, same dyno, same night, same tuner. PULP 98 VS E85 Same boost. As tuned PULP 98 VS E85 at 2 bar Basic spec list is: GT block Tomei 2.8 (9.0 compression) 270 @ 10.25 cams ported head HKS GT RS's HKS dumps and front pipes kakimoto full mega N1 cat back Power FC ID 2000 cc injectors, Nismo lift pump and 2 bosch 044's feeding the engine + all the bullcrap to support it. The midrange improvement on E85 is amazing! Once it comes on the tacho just flicks to the limiter. RWD is quite fun!

My clutch hasnt got any issues... It held well with the 8000 RPM launch up the street the other night!

What size is your rail? I have had these in both the stock rail which is 10.5 mm and a 11 mm sard rail. They are 11 mm. Im in Sydney.

Hey guys. Just have a set of Sard 800 cc injectors for sale. Only reason I changed them over was because I went to E85 and threw a set of ID 2000's at my car. They have done about 15,000 kms and were cleaned about 3000 kms ago. No issues at all. Price $520 Delivered anywhere in AUS. Cheers
