HiBread

Nice bit of humor there mate, and deserves a bump! Yeh, seatbelts aren't awefully exciting. I'd imagine most people wouldn't know the answer to your question, so probably best asking a seatbelt expert; someone who makes money selling seatbelts.

R31Nismoid: Yeah thats exactly what ive been thinking. I would have thought that if a repairer was going to spend 11500$ on an engine build alone, then they would do things properly and write down all the mods that have been done along with the engine number for future reference. Thats what ill do today. ishh: I agree, 300rwkw isn't quite enough

An R32 GTR i looked at on the weekend has some basic mods. Power FC computer, 12psi boost, exhaust. Stock intercooler / turbos etc, and had a print out of its dyno run. 238kw (at the rear i guess) But i guess thats not the stock figure you are looking for...

Im really going to have to find out as much as possible about this 800hp motor rebuild I know that its impossible to actually know for sure, but is it fair to assume that those sorts of things "should" have been done on this engine to be able to give it the 800hp label? Im talking about oil pump style upgrades etc. There must be tonnes of upgrades to a powerful engine other than O-ringed / forged pistons / conrods for a rebuilder to give the engine that sort of "class". When i say assume, im not going to literally assume they are done and go buy the car on that assumption, but are those sorts of things stardard routine for an upgrade of that calibre?

So the airflow meter "is" an issue? Ill have to look up this oilpump collar you speak of. An expensive upgrade?

Hey guys, lots of feedback, cheers! I guess i now have more doubts about this car now than i did before, thanks heaps! haha My problem with getting a clapped out one for 15 grand then spending the money on getting it up to scratch is that it will be an awefully expensive journey... - 15k for the car - at least 8k+ for the engine rebuild to support more horses - 6-7 grand on new turbos / fuel system - 3 - 4k on new clutch - 2k new computer - 2k for rebuilt gearbox (might not need it) - 2-3k? for cooler and exhaust and then you can probably slap on another 5k just for other bits that are worn. So you are looking at a build cost of $38k at the very lowest, or more realistically $42,000+. Ive seen "mega money spent on my show car" cars for 40,000. The engine was rebuilt because the last owner blew it. The owner himself told me that, and this is why im concerned about the conditions of the turbos. He was probably running the boost far too high for the injectors/fuel pump (and/or the tuning) hence started melting stuff with detonation. These are all things i need to weigh up. I should go and visit the repairer again to see if they can find more about the rebuild.

Gday N1GTR, I have no idea of the power fc version. What benifit does this D-Jetro version you speak of have? The engine rebuild (which included the power fc and clutch install) was done approx 3 years ago. The clock has only done 4k since then... which does sound a little sus. I have spoken to the previous owner (as this car is being sold in a car yard), and he sounded legit. Didn't seem to have anything to hide. But anyway.. the clutch upgrade is on the receipt for the engine rebuild (ive checked the paper work with the repairer and its real). It has a $3200 figure next to it, which seems pretty pricey to me. It feels quite heavy under the foot, but regardless, i dont plan to put 800hp through it

Cheers for the reply GTRGTR So the stock airflow meters should be fine?... Wonder why the shop suggested a new airflow meter... just take more money from me? You mentioned cam gears. Do you mean the actual cam gears at the front of the motor (an adjustable type?) or do you mean the cams themselves? Btw, do you know how much im looking at for new cams to suit a 350kw setup and how much of a difference they make? The car already has a power fc and a large (looks pretty meaty to me) trust cooler. I dont think the exhaust is standard, but does't really have a nice note to it. Big dolars for an upgrade? The standard airflow meters, are they a physical rotatiing type system (lack of a better phrase) or do they use some sort of heated wire type thing that measures resistance? It would seem to me that the first type would have a physical limit on how much it can measure; hence the requirement of an upgrade

Thats a great argument to give the salesman to get his price down, cheers!

Hey guys cheers for the responses! and so quickly! The engine has been rebuilt to an 800 hp rating. This means that the internals have been built to withstand 800hp. Obviously to get this you'd need some serious other mods which the car doesn't have (ie turbos / injectors / fuel pump) So what im after is some guide to how much boost you can run with stock GTR turbos / injectors / fuel pump / airflow-meter. (Or rather what boost / awkw you should expect) And also if i was to upgrade the turbo's / fuel pump / injectors etc and try to get 300-350 kw @ wheels, is a new airflow-meter in order? To answer your question Angus, I just want a nice powerful street car To add more information about the rebuild, it was done by Tilbrooks in Adelaide. Does anyone know of their reputation?

Gday peoples! I'm looking to buy an R32 GTR as soon as i find one I like. There is one particular GTR that i've found which has caught my interest. The previous owner blew the engine so had it rebuilt. The engine has been rebuilt with forge pistons etc to an 800hp spec. Along with that it has a new Exedy twin plate clutch, a rebuilt gearbox (just the syncros i think), and an apexi power fc. I have a concern that the turbo's maybe on their way out so have contemplated a turbos/injectors/fuel pump/air flow meter upgrade to take some advantage of the strong motor. (It already has a large trust intercooler) I guess one of my questions is, how far can one push the standard setup? How much boost can you run before you risk the turbos, or risk the motor by starving it of fuel? What expectation should i have on the standard injectors and fuel pump to deliver fuel? Even the airflow meter? Another thing which im a little concerned about is an engine noise it makes. Apparently the noise im hearing is the forge pistons. The noise goes away (mostly) when its fully warmed up; but still, its not as quite as other RB26's ive heard. I spoke with the mechanic at the place where the motor was rebuilt, and the first thing he said when i mentioned a noisy engine when cold was "forged pistons". All this is pretty new to me so any help will be appreciated! Cheers!
