Sounds good, any further engine mods planned? I hope to get a similar result, once I get my finger out and get the headers fitted. I keep swithering about doing cams as well, typical scope creep for a car that was supposed to stay stock.

Do people build their own fuel returns for the 350z or just buy the kits?

How do you find it to drive after a 350?

That is a nice result, is it noticeably quicker to drive than stock now? What is the current engine mod list?

You can basically use any appropriately sized supercharger, but you will need to fabricate a mount, tensioner setup, get it in line, fabricate pipework etc. Mini supercharger would be too small. Unless you have the skills to fabricate/weld I would pass, also being a pioneer is normally expensive. However if you enjoy a challenge, anything can be done. Simplest/cheapest would probably be a Eaton M90 (ebay from a Jag etc) onto the lower intake manifold manifold, and a big hole in the bonnet, simply ugly and effective, could possibly be done with a plate style adapter. I think a DIY centrifugal would be fiddly, and I have not seen cheap OEM centrifugal superchargers.

MAF based WOT with long term fuel trims could give an initial HP increase from breathing mods due to a leaner mixture than stock, assuming stock WOT is safe/rich. Long term fuel trim would then adjust injector pulse duration to due to continual difference in short term fuel trim target/value giving a higher than stock, but lower than when the mods were fitted. MAF is different from speed density/alpha N, the MAF can read increased airflow from breathing mods, and then take a value from a different cell, so slight increases in efficiency will be "tolerated" by the ECU, but large deviations will not, as the cell values are not there to support it. Stock ECU will allow a certain amount of variation due to wear on components, sensor drift, differences between engines, fuel octane rating etc. A proper live map will optimise all the cell values for the cars increased VE etc, giving a larger power gain. This would appear to be supported by people fitting headers and getting a small HP gain, then a remap giving more.

Did you have to get it from the states?

Ignoring cam install costs, would a set of "stage one" cams, eg Nismo R-Tune, Tomei PonCam, JWT S1 give a significant improvement on the above car?

Good info thanks. Is a revup oil pump a good upgrade in that case if you were fitting cams/springs/retainers?

What limits RPM on a DE?

What is your planned spec Ben? Long tube headers £1500 JWT C8 cams £ JWT valve springs/shims £ Uprev £450 Plenum spacer? Ben UK 75mm TB? Injectors?

Would you not just build an MOT cat pipe you fit to the centre section for MOT? Even if you were running true duals you could easily make a Y-cat-Y to make an easily swapped section, then just run straight pipes in that section the rest of the time, V bands or bolt through flanges and it would be a quick swap.

So cost wise on DE assuming the Superstreet/Onpoint numbers are correct and using their mods anybody fancy filling in some blanks or correcting prices? How much gain did Sasha get by using a custom upper plenum rather than just a spacer? 205-210whp Stock £0 272whp Longtube headers £1500 Race exhaust £600 Custom intake plenum £ 90mm throttle body £250 Remap £450 Total 292whp Longtube headers £1500 Race exhaust £600 Custom intake plenum £ 90mm throttle body £250 Remap £450 Stage 1 cams £900 Total £ 326whp Longtube headers £1500 Race exhaust £600 Custom intake plenum £ 90mm throttle body £250 Remap £450 Stage 2 cams £900 Valve springs £ Total £ Note "With 300 degrees of duration, these cams don’t idle all too well and won’t run very smoothly below 2,000 rpm, but they make power." 372whp Longtube headers Race exhaust ITBs JE pistons Eagle rods Stage X cams Valvesprings Ported head Injectors Standalone ECU Mapping Total £ Note "the engine is constantly surging and will not run below 1,500 rpm." 413whp HR engine swap 3.7 stroker JE pistons GTR rod bolts Valve springs Cams ITBs Injectors Fuel pump Custom airbox Dry sump Standalone ECU Mapping Total £ DE supercharger costs 350 WHP Supercharger kit £ Uprev £750 Total £ DE supercharger costs 400whp Supercharger kit £ Uprev £750 Fuel system £ Total £ Personally my current plan is Plenum spacer £170 HR exhaust manifolds £110 Decats £200 Uprev £450 Total £930 Not sure whether to do cams as well, jumps the cost up a fair bit, Nismo exhaust already fitted as it came with the car. The above ignores labour costs, assuming DIY.

£200, 1988 Audi 90 2.0 10v, it had no MOT or tax, it didnt even start

Abbey fit them to DEs http://www.350z-uk.c...lds#entry937642 HR v DE (pictures stolen from the internet) As far as I can read you need to use HR decats or HR cats with HR exhaust manifolds on a DE.

HR manifolds can be used as an economical upgrade on a DE, fit HR decats at the same time. Would you fit the manifolds yourself or pay to get it done? That makes a huge difference to value for money.

HR or DE decats?

Yes it has been resurfaced in August. I was last up at the start of August. Crail thrash day?

Looks like a fun day out, nice catch at the start! I did the same thing at Clarks but lacked the talent to catch it and ended up in the gravel Thanks for the build thread, it is a good read through.

There are universal 4" (I think a K1 is 4" tips?) exhaust bungs on ebay, you will probably have to drill the new bung to match your existing exhaust

Thanks, always a relief with a new car. Quaife arrived, comes with instructions to shorten a shaft. Opened up the spare diff for a quick look Whiteline diff bushes are on backorder with Clark.

I bought a set last night I am afraid, your ones would have been much closer! Thanks

Looking for HR decats thanks

Looking for a pair of HR exhaust manifolds. thanks

Put the front end back together last night, topped up the oil, ran it up to temp with no leaks. MOT passed today with no advisories! Power steering cooler arrived today so the bumper will be coming back off to fit that. I think the car deserves a pair of decats for passing its MOT
