Mate.. a full rebuild is going to be 13K ontop of that. so the difference is between 16 and 19K, which isn't 50% anymore...

The 6boob low mounts I've seen are also true lowmounts, I would presume crg will be similar due to the aforementioned point that they are very similar in their products and methods etc

Best i got with my 32, using a haltech with wideband and target AFR cruise was just over 10L/100 from, Wagga to SE of melbourne. Bit of traffic getting through melbourne too so could have been even better, the instantaneous cruise Fuel usage was sitting around 9.x/100 at 110 on the Hume. Not bad for a car with a terrible drag coefficent. I'll be interested seeing how the new engines runs. Higher compression but bigger cams.

They have a lot on their facebook page, had to go back to august to find a twin scroll/gated Rb manifold though, most people seem to cheap out and get single gate T3's

Most people here would recommend the Quaife front diff over the nismo, as its a helical type diff instead of mechanical plates, helps with understeer under load. Also my diff guy doesn't like to install mechanical fronts as too much of the diff housing needs to be ground down to make them fit apparently Additionally, note that for the gtx turbos, they aren't a bolt in affair, to get mine i needed to find a rear housing to suit and then get a front housing machined. As was mentioned in the first page, you should probably be able to get a turbo shop to do that using tx 2863's into your existing turbo housings. why not 2860's? because you cant machine something to be smaller than it already is.

That is a significantly more useful table The gtx 2863s seem to make power just fine with GTR compressor housings, there was the white 34 that made just shy of 500kw at 33psi with 63's on E85. Not seen any results for gtx2860's so i guess i'll find out with mine when they're on there. But again, you'd need to run some stupidly high boost for a non E85 setup.. 25psi is quite a lot on 98 isn't it?

For what its worth, i went around and made a small table of all the lowmounts that are available and somewhat popular thesedays (no greddy turbos...) You can see the different wheel sizes which may help you get an understanding of all the different options. Basically the 2871's are called '-10's' for the gtr specific housing set, but they have too much compressor for the exhaust size when used on a 2.6/2.8.. -7's and -5's are gt2860 variants with gtr specific housings. as you can see the -7's have a smaller exhaust wheel and compressor inducer. -9's are technically a gt2859 but have a compressor halfway between in terms of its flow rate. Basically -9's are your go to for ~350-370awkw and -5's are 450awkw on E85, a bit less on 98.

Spool just uses a local engine builder to build their engines, as I understand it. So I just went to said local engine builder. VCT would be nice. I ummed and ahhed about using a NEO head on mine but there was too much unknown about getting it to fit. There's a guy up here who wants to do it though so maybe oneday...

Different compressors on the gt2860 core from garrett. I personally wouldn't go with them as they are... miss matched. Best bet is to just go -5's and get what they get. they may not give 450kw but you really aren't going to get a better pair of stock position turbos on 98. and if you ever do go E85 should get you close to the mark but you'll need to upgrade the entire fuel system of course. I don't buy into the whole "revs less" argument from strokers. Yes its probably got a lower maximum revs but i get the impression that the valve train limits that on any possible engine configuration regardless. I went for a ride in a Spool 2.8 equipped car and it honestly seemed more willing to rev than a stock car. That tipped me over the edge on my decision, I think it was the full conterweighted crank that makes engine a lot nicer to drive. I went for a target of 9.5:1 on mine however it will barely be run off of ethanol so that should be fine. Turbos are gtx2860's and Cams are the unigroup ones, 260/10.85, so it should go alright and make good use of the E85.

I probably wouldn't go for the GTX turbo options if staying with 98, they love boost, you'd want ot run 30psi wtih them but i'm not sure thats' going to happen on 98. Spool 2.8, big sump, all the usual oil system enlargement, bigger oil pump, -5 turbos, good exhaust, good cooler, id1000 injectors walbro 460 intank pump, new ecu maybe, away you go.

depends how you value the sticker really, and how much someone else does when you feel its time to sell. the differences were wheels, brakes and suspension mainly. All 3 things that are common and easy to change on a normal R32, so to me its not worth more than 1000 bucks more than a normal one. Heck you could even put a sticker on a normal one and come out 20K better off if you just care about that. Of course i understand that people care about cars for rarity etc, though for me it seems pointless if that rarity isn't anything special.

I would presume the result of this thread was: Headstuds, -9's, cam gears, injectors, fuel system, E85 ecu and a tune?

The costs of swapping out to -9's is way way less than the costs of going a single if you're only after low 300kw's, so suggesting a single swap is probably a bit out of place in this case. but yes, -9's. Not 100% sure on the oil drain but i'm sure someone will be able to help you out there. Note you'll need a oil feed restrictor also. I'd suggest getting braided oil feed and water feed and return lines while you're changing out the turbos, makes everything so much easier.

CRG is located on the goldocast, fair few blokes around here using them, they also seem to sell a lot to the XR6 crowd. Seems like a fine quality product and very similar to 6 boost. personally i'd be more interested in a comparison between a 6boost/crg style manifold and something like a fullrace manifold. Also, you really, really, really want twin scroll.

That's got to be the weirdest combo of intake and exhaust cams i think i've seen on a RB

*smith voice* it is... inevitable *smith voice* I'm still doing twins... for now.

Sigh. the more and more I look at it the more and more confused and unsure I get. Wonderful. Upon further discussion with mike, his comment about the fuelab being loud was when it was at full bore (FPR disconnected) at idle/priming. Obviously you'd hope that the exhaust would drown that out at full bore. So maybe that's still an option. In essence, I need a pump system that is capable of flowing 500lph (100% duty cycle on 1250cc's) at around 75psi (43.5psi +~30 of boost). That rules out a single walbro, and even the voltage boosted option above is not quite up there. There is a guy developing a twin intank hanger for the walbros so that may be another option. 450LPH in an ideal situation. single walbro may just be able to phone it in when running 18V... Otherwise, surge tank, which I would really like to mount under the car. Few options for those around, most to suite Bosch style pumps, however the issue there is that they are a: generally all regarded as loud, B, generally all not E85 certified. the Holley sounded good until someone mentioned its temp rating, although that does sound a bit low and perhaps an error. A surge tank with twin internal pumps is probably the go, however it'd need to be full custom (not necessarily a bad thing as other tanks may not fit in anyway) and would require a bit of work to make it fit. Pump choice becomes interesting. Walbro 460's would be a bit overkill, twin 255's maybe not enough, then there's all the DW stuff, AEM etc. Fuel line wise, I've noticed a lot of people change the rail, and a fair few also change the lines. Most people seem to do it "because" though, i'm wondering if there is actually a definitive need to do this? I mean, 500lph through a 5mm fuel line is ~7.5m/s which doesn't really seem to bad on the face of it. I know you're doing a bigger inlet (-6?) Jono, thoughts on why you did that?

Yeah, external is the aim regardless. Did some research. Seem good in theory, not many people 'round these parts have used them yet though.

So i'd been waiting for a second person I knew to install a fuelab pump. End result is same as first person. loud. So i'm back at square one. Suppose i could just grab one of those generic under car surge tanks and a pair of the new DW pumps. Figured i might as well upgrade the fuel rail and lines aswell, so now i need to do my research for that in terms of running it to the front and what rail to get etc.

Question is how loud is it?

That's now how injector pressure works... if the fuel pump is supplying 83psi, and the boost pressure is 25psi, the pressure across the injector is 58 psi, so the flow rate will be the 1180cc pressure you mentioned. Which isn't enough fuel to flow the quoted power figure, etc.

When: 7:00pm, Wednesday 9th of March Why: Good food and beer See you guys there!

The good news is thst it's okay because the hose won't magically melt from e85. The bad news is the same can be said for the rest of the ones you replaced

Well, the gtrs rear is the same as the -5/63 etc, I was just noting that there was an option out there that had the same flow as them except a smaller lighter wheel. Simon may have had heat issues on the track, but he did have the response of -5s and almost 500awkws aswell, noting it would be a pretty kickass Street combo

Gtx2863s have more air flow rate than the gtrs turbos
