GTR-Ben

Well yes it needs a little "modding"

Yeah thats actually how I am doing it. I am using the RB30 Bottom and the Rb26 Top.. and there is only a very small gap. I have bent the metal into shape.. and then just spot weld it on at the back. Easy. Paint it, and it will look mint.

Bend up some metal, rivot it on, Paint it.

Yeah thats the fun part.. Oh and ignore the dirty cam covers.. they are getting painted.

Got the turbo bolted on. Just waiting to get the car back to stick it all in

Yep we shouldn't post after a few drinks... But you didn't get my point. I (as well as others) would call a rising rate FPR one that has a ratio other than 1:1 like any stock FPR on a turbo car. Yes a non turbo car has a non rising rate reg. Malapassi are refered to as rising rate with the ratio other than 1:1, where if you buy the Nismo stock replacement it wont be. From there I said it is a waste of time using a "rising rate FPR" (meaning one with a ratio other than 1:1...!) when you should have the right fuel pump and injectors to supply the fuel instead of pushing the whole system. They are a good cheap alternative.. if you don't want to go the whole way and buy bigger injectors etc. Saying that I have pushed a stock GTR with stock fuel system into mid 11's, that car ran a Malapassi FPR. On that note... do the job right. Get a good pump or as I have done, plump another one into the system to keep the flow up. Get a good 1:1 Reg like the nismo unit.. and have the right size injectors for the power you are making. got me 4 door?

I think you missed my point. When I (and others) talk about a Rising Rate FPR., I am talking about one with a ratio other than 1:1 like any stock FPR on a turbo car... Yes a non turbo car has a non rising rate reg.. From that point I said there is no point getting a "rising rate FPR" (meaning with a ratio other than 1:1) as you should have the right fuel pump and injectors to meet the engines needs.. not pushing them past 100%. So from there.. Buy a good pump, and a good 1:1 FPR like the Nismo should do the job. I have quite often just plumbed and extra pump in the tank for a backup, and bolted on a fpr to control the pressure. I have tried most brands including the malapassi, nismo, aem.. they all did there job. A Rising Rate with a ratio increase is a cheap way to push the system though if you don't want to fork out for right injectors etc. Saying that we have pushed a GTR with stock fuel system to mid 11's, this car had a Malapassi FPR.. :headspin:

And when we talk about a "rising rate" regulator. They actually have a ratio as some have said... apposed to the factory ones as someone called rising rate, but are in a ratio of 1:1 with boost pressure. A rising rate FPR will increase the fuel pressure more than a normal regulator as boost increases... which is a waste of time if you have a good fuel pump that can actually keep the fuel pressure and flow you need. Spend your money on a decent fuel pump and injectors to supply fuel to the power you actually have. No point having 6x 1000cc injectors with your 400HP car. Same thing goes for having 6x400c injectors in a car that has 600HP and pushing them to the limit.. A simple nismo reg will do the job for most cars, its the fuel pump and injectors that do the work here.

Look at the nismo one that bolts on. It looks like stock. All it does is restrict fuel on the return.. how can a different brand really have that much difference? Skyline-Dave. How can it control boost..? And unless you running enough fuel for 4000HP I can see the small size hurting? And I would say the Nismo one is all you need.. they have been proven to work. Rising Rate is not always a good thing.. you should use tuning to get the fuel right.

No never saw that... show me pics Great.. well I will lower it as much as I can and then make a custom bonnet.

Yeah they make those funny engine mounts that lower the engine quite a bit. That's why I am going to make a plate to do it.

Yeah Joel.. I don't think it's going to fit into my S13 even with a GTR manifold. Considering people have to cut the bonnet parts out to fit a stock GTR motor in. 30mm higher, no chance. I am going to lower the engine as much as I can. Looks like my turbo will hit also.

Is this with the RB25 head and the manifold going over the top of the head that hits the bonnet, or with a GTR style intake manifold. Thought it did fit in an R32 with a GTR style intake?? I'm guessing you mean RB25 when you say the front of the plenum hits the bonnet. Probably going to be stronger to make a spacer plate than to drill holes in the alloy engine mounts blocks..

I have some pics, just havn't uploaded them yet. Did you have to assemble it yourself SK? This one came with the liners etc all done and crank installed. Looks like a pretty big job involved putting it all togethor if you had to.

I was talking to a certain person down here who owns a Stagea with a GTR Engine with 2540's making 700HP at the crank. Now that is a fun sleeper! He also has an original 260RS. Shame they look like a Volvo though.. A Stagea section would be good

Oh I have an actual OS RB30 in the garage at the moment. They actually don't mount an idler or anything higher like some of us have for our cambelt due to them supplying a cambelt that is custom made for the RB30. It also comes with really nice Cam Sprockets. Quite a bit more coin than making your own 3L though.. Quite funny comparing it with the old VL RB30.

I think he means a RB25/30 engine, not a GT2530 Turbo. That would feel like a NA This engine lowering looks promising, only trouble for me is I have to space out my Swaybar as it is, lowering the engine another 25mm would mean the swaybar would have to be spaced out a lot more.. Worth a try though if it means not having a huge bonnet scoop.. My old RB20 Powered cars would max the AFM out at the top of 4th, which was always about 198km or so. Was really annoying on flying 1/4 runs.. had so much more to give but it would only let you coast. It is damn scary when it cuts out like that at those speeds. I'm not running AFM's on this car so no probs hopefully.. just other ones.

offset 40

Seen Twin GT2530's make 390kw with stock bottom end. They are good turbo's for a street car.

Get Joels guide or skim through the pages here. A bit more up to date and more info than that guide.

I believe the RB30 fits under the Skyline bonnet without major mods.

I have seen skylines making over 600HP at the engine with the stock lines, so I can't see why you would need to for 300rwkw?

Yeah be a nice engine when it's all rebuilt etc though

RB30 is one option, but you must remember that there is a bit of time involved in drilling the head bolts and setting it all up. Considering you have to replace all the bearings in the RB26 it may be an option. Need to make sure he has everything cleaned properly. Head and Block. It's a pain in the ass when the engine has ceramic contamination. I think the person who replaced the turbos before should have checked the engine.. as installing new turbos on a car that is contaminated can just eat the bearings in the turbos and they will be stuffed also..

The reason I asked if you have had a turbo blow is that the fact that your car has scored the front 3 bores.. If a stock ceramic turbo blew there is a strong chance that it spat some of the ceramic dust into those 3 bores, and in time it does eat into everything alse. A bigend is very obvious in most cases, it will sound like someone is in there with a hammer. Having the ceramic dust in the engine will cause the bearing to wear a hell of a lot sooner though.. Requires a complete engine clean, and quite often most parts to be replaced. Get your turbos checked also..
