He changed both the tie rods (track rods ) ends already. I think the car need to be on a whel on ramp and the steering wobbled while ther eis loa don the wheels , you should be able to feel any play in the suspension. Have you had the car 4 wheel aligned since you fitted all the suspension items? I have had cars wrongly tracked and they feel horrible when driven on the road.

Hi , yes we have tuned a few 296bhp cars , they all run lower than what Nissan claim we have found. But the mods you have done so far have given the normal gains , but I feel you car needs a Y pipe at least get the more mid range gains that I feel you car is still lacking. Race cats will help as well , but the alloy pullies I feel are a waste of time. I have issues with removing the stock front pulley and engine balancing issues. I will look at the PM and get back to you. Mark

welcome , thats looks a nice car , enjoy it. Mark

have a read of this thread. We have currently tuned over 60+ 350Z with the Uprev sysyem on our own in house dyno.

Send me one then once you have it domne I can try it in my UK car.

The 296bhp cars never give 296bhp we have found while we have been tuning the cars. They are always approx 20bhp down when totally stock. Just use the dyno as a before and after tool , the car gain a good chunk of torque after the car was remapped, the before run is with all the parts added with the STOCK map the after is the same items plus a UPREV remap. Remember all dyno,s read different so dont compare another dyno to our dyno just use the same dyno to compare gains.

What do you need to know re the dyno plots? The 1st plots is axle hub BHP and Torque. You need to divide the hub torque by the final drive ratio which is 4.651 to 1 this gets your a flywheel torque figure. Hub bhp you can add 35bhp to get a approx flywheel bhp figure. The other dyno plot gives you flywheel torque(the same as above working out) and air fuel ratio. Any more questions ask away , PM me your email addressand I will send you the dyno plots via email.

To be 100% honest they do give a little better flow so will give a little more BHP/TORQUE but unless you can get one pretty cheap I wouldn't bother to be honest. Just fir a free flowing panel filter and a remap makes a huge difference.

Did you remove the heater controls and start the car up? This will throw a CEL as the heatercontrol is on thr CAN bus circuit. Make sur eit is connected the dis connect the battery for a couple of minutes then re-connect this should turn the light off again. Mark

System really needs to be bleed diagonal, i.e blled left front with right rear , inner then outer nipples. Then bleed the right front with left rear , inner then outer nipples. Then you should pressure bleed the system , pump up the pedal the crack open the nipple to allow the pedal to go to the floor.

We run the motrs for around 20/24 runs , which then they need a rebuild. Bigest trouble we cant strip the motors easily as it is major work to remove the sump or cylinder heads. So we normally only have 2 motors in the UK and 1 in the US being rebuilt, but as it is the beginning of the year we have 3 motors ready to go. We find a few things that the motors have trouble with; running the car on the ORB ( making boost on the line) it is very agressive on the front cam lower sprocket, the cam buckets and the exhaust valves. The motor runs to 10,000 rpm with STOCK Nissan cam drive chain and gears so w ehave to keep an eye on these. Crank rods and pistons and bearings we now seem to have it all under control now . Head gaskets we use a normal high end performance gasket with very good quality head studs.

We have 3 engines for the drag car , 2 are on there way the other one that was used for the map build is being refreshed before being shipped.

Mine JDM is a ST and it is only 276bhp like every other JDM car , ST doesn't have any extra parts or a different ECU map from any other JDM manual car.

All the DE engines have the same BHP , 278ps I think.

Hi Guys, inlet port design is different on the HR motor so the DE/REV UP wont take the HR plenum at all. Re fitting a HR into a DE/REV UP car isnt a bad job but you need a gearbox/engine complete, engine wiring loom , dash clocks ( due to the extra rpm the HR runs) and ECU. 1 interesting fact you boys might like to know the 370 VHR motor , the short motor i.e block size is the same size as the HR motor ( the increase in capacity does make any difference to block size) so the VHR bottom end will fit with HR top end parts so you can have a 3.7 ltr HR pretty easily. Agree plenum spacer panel filter and a remap will make your 28 bhp car go far better. Mark

Seen this a few times normally it is bad contact on the throttle body connections. We tweak the male terminals to make a better contact normally sorts the problem we find. Any more questions ask away

We have developed our own drop links. We use heavy duty sealed joints. Far better quality than the stock links and more robust against the british weather than some of the aftermarket kts around. If you look in our own Abbey part of this forum you see pictures and prices (I think I have updated the price for 20% VAT)

Been away in the US for a week dynoing the 2011 Project Zed engines. thanks to Performance Motorsport AET turbo's 6 boost manifolds Shane Tecklenburg Gizzmo roll on Easter weekend when we can unleash the motor at proper boost levels.

Ian, running the jets they said only yielded around 40 bhp , I have leaned the car off to make 50 bhp. Try what they say but the balls fairly in your court, we deal with the Rev up motors daily we kinda know them very well. I even let you use the dyno with Wizard helping if you want. I have seen a bigger pile of broken engines parts while I was in the US a weel ago through badly tuned 350Z's and G35 cars. dont get bhp crazy , supercharging make a less agressive torque than dropping in 100+ bhp of gas. I have seen turbo Z's break the rids at 380bhp , the cylinder pressure caused by gas is more agressive than turbo power. But if you want 100+ bhp go for it but dont cry if it breaks.

Rev up cars have all the same internal stuff as the DE , same con rods that break when you run to much torque Ian , just like I have told you before. Nothing is forged in these motors. Th Rev up engines have oil buring issues as well Nissan changed the ring design on these motors , which cause these cars to burn oil , if you order a set of rings for a rev up engine nowdays you get earlier DE pistons rings , that will stop your oil usage. You need to keep an eye on the oil level on Rev up motors.

Yes Ian I think so, was going to ring them later.

Stock 313bhp motor will run 500bhp without any internal mods I am sure there is a supercharger kit made in the US I will ask my friend who makes it. You need all the normal mods like fuel return system injectors fuel pump and a retune of stock ECU. HKS don't make a S/C for the 313 motor thou. I personally you just fit twin turbo's.

Yes agree but even without this expensive item they go far better after a remap

We have tuned a few 296ps cars. Wasso basically answered most of your questions. Basic tune I would say plenum spacer/ air filter and remap. we do gain MPG, improve throttle response , generally make it better. There are a few options to go after this as well , that we can discuss. we charge £402-00 inc vat for the remap this includes dyno time and we can do the job while you wait for the car. Any questions ask away , your find dyno sheets on this forum under our Abbey banner in traders.
