Hello all i have started this thread because at current my engine is being rebuilt by eric at a2zed and while thats getting done i have managed to pick myself up a vg30dett engine and auto transmission off of ebay for a very very cheap price almost feel sorry for the guy who sold it but an absolute bargain for me. with this motor i am planning to get it rebuilt or perhaps having a go at doing it myself of a period of time. i have been told by the seller the engine was in good condition and was going to be used for a conversion that never went ahead. parts missing are turbos, ECU/wiring loom, and timing covers which im not to concerned about as i am in no rush for them and was planning to upgrade the turbos anyway. what i would like is for anyone who cares to have any sort input and give me any ideas about what parts, brands or even things i should be doing with this engine. idealy i would like about 500-1000 rwhp i do understand it will cost alot of money but like i said im in no rush and it will be done over a period of time and my current 300 is getting its own rebuild now so im just after ideas. bareing in mind im not the most mechanical person but i figure if i attempt to do this myself its the only way i will learn. thanks in advance people.
i have seen rebuild kits rangeing from $1600 upto and over $3250 but im not sure i want to go with a kit or if i should go piece by piece if you know what i mean. obviously these kits are not going to give me the hp i want but might give me the base i need.
hmmm well if your chasin upto 1000hp., diyer in the shed prob isn the best way to go, especially if your not too mechanically inclined. takes alot of precision work and tools for those numbers and ya cant just slap things together.. i dont know your situation.. but IMHO id research,, research and research some more.. get parts together and pay a workshop to do the machine work thats abit much to do in the shed i.e crank ground balanced, block bored/honed pistons installed etc same for any head work, then do things like valves, cams putting everythin together myself.. 500hp isn that hard to achieve with proper supporting mods and bigger turbos ..ive seen even standard blocks achieve those numbers and more..and all things depend on what you want it for, 1000hp on the street is a bit much. but great for a dyno queen.. cost is another.. i know you said your in know rush but do you really wanna sink big $$$$ to make 800-100hp all so it can sit on a dyno and make the lil computer screen read yay 1000hp.. just my .02c.. sounds like ya have a fun project goin. good luck scott
im planning to start the research once i get back home...yeah thats the plan get all the part together but obviously any sort of machineing i wont be doing myself. i would be quite happy with 500+ and yeah your right it is alot of money to spend for it to sit on a dyno i think was just curious to see what people on here have to say and think about the idea
if i had unlimited $$$ 1000hp zed would be a fun novelty what is eric doin to your current motor?? if its gettin rebuilt with forgies.. a good set of turbos and supporting mods, exhaust, fuel system etc etc will get you to 500rwhp
my current engine was suppose to be making 366rwhp but the guy i bought it offeither didnt know or didnt inform me that the engine was on its way out and as im from melbourne and was up in qld visiting family when it decided to start playing up an awfull lot i asked around and had been talking to eric on here for a littlw while and took it into him to have a look where he gave me the diagnosis. for now im just getting a basic rebuild to get it up and running properly again as my funds wernt there to get much more done than that...hence the second motor to rebuild for more power and at my own leisure. i think what i need is a list of exactly what i need and what work i would need done to the engine along with a list of supporting mods is what im looking for. i would have loved to have gotten the forgies done with this build but simply didnt have the money available to go that far if i didnt need to get back to melbourne and get back to work and had the money i deffinately would have gone in that direction.
Hi jwweston, seems like you and I are about to embark on the same voyage although your destination of 800-1000rwhp is not mine, I bought a z from a guy with a motor supposedly rebuilt by a known engine builder here in johannesburg south africa with eagles, JE pistons, ball bearing turbos. To cut a long story short it had none of the good stuff and was a stock motor rebuilt badly. With a tight budget but wanting a little more than stock I bought the ACL bearings, gaskets, oil, water pumps, belts tensioners etc and as well as 040wiseco pistons which I will fit to the stock rods as eagles were just out of reach, 550 injectors and light weight flywheel and upgraded clutch. The turbos are being modded with bigger exhaust and comp wheels by the turbo specialist as gt2871 are way out of reach. I see the rods and turbos as my limiting factor....any guess what sort of hp this set up would result in.
1k rwhp is insane, how much work does a zed need to handle that?, good luck, out of curiosity how much is it just to get a workshop to rebuild a tt engine and install on an na?
I would think the biggest issue when chasing 1000hp in a zed (apart from all the right internals and workmanship) would be probably converting to a quite large single turbo, and then finding somewhere to mount it. A billet crank girdle would be a good idea too. I can't see it be very streetable though. Look at Rob260's build. I shudder to think of the cash that went into that and still 'only' 625hp Ben
Don't take this the wrong way, but you need to do ALOT more homework. You are talking about two radically different engines there.... As a starting point think about what you want to do with the car, your budget, and your timeframe.
Bore the cylinders for bigger forged pistons!! Look up cryo treatment as well. Its gonna be tricky to keep it streetable especially switching to big single turbo and aggro cams (lagville). Personally i would keep it twin and find the biggest 2 turbos you can find to fit. Im not sure if any street 1000rwhp zeds make that without nitrous injection.
all good mate i i said from the begining i started this thread to see what ideas people had and yes i know i need to do alot more research and this thread is the begining of it...my time frame is as long as i want i am in no rush
What about budget? What is your "goal" with the car? 500hp/370rwkw is very achievable but will probably eat up alotta cash if you do it right. And I mean alot. Figure built engine, GT28RS turbos, radiator, intercooler, fuel system, management.... machining/balancing. 1000hp... never say never BUT it is getting a bit fanciful.... A couple of cars on TT.net have achieved this using front mount turbo kits. Personally I think they are ugly as... you are also going to need a custom girdle if you want the motor to last. Not talking myself up but have a read of the thread in my signature. I reckon it is one of the most thorough, detailed builds you will find and still a long way from 1000hp. Also have a read through the motorsport pages at www.300zx.com.au and see what they have done to build a competative circuit car. Not all about big power either. As I mentioned above, I think if you work out what you want from the car and then work to that you will be alot more satisfied than if you are shooting for an arbitrary hp figure. If you're in Melbourne you should probably have a chat to some local shops too. I gather from your first post that you are going to do the assembly but you will still need someone to do machining/balancing/tuning etc.
... might i add... Its all well and good to have a motor that can push up to 1000 HP, but have you thought about everything else? A gearbox capable of handling that power? A clutch/flywheel strong enough, driveshaft/tailshaft, differential and other running gear, you will shatter axels and probably warp the chassis, so you need retaining work there too. You'll need huge wheels and tyres (just another little thing to think about) and dont forget an engine management system capable of keeping that bomb of a motor ticking. Your looking at $40K+ on JUST the motor before turbos and driveline mods. IMO if you just want 1000 hp for the sake of it. Go down the Supra road. Been done heaps and plenty of experienced tuners.... What ever you do, Good Luck. Elie
I heard the conrods were forged from stock, so i daresay they may not be as limiting as one would think:zlove:
A safe 500rwhp tt is going to cost 20+ make no mistake about that. You might get 1000hp out of one of these engines, but it'll be like trying to defuse a land mine, one wrong move and good night.
Totally agree, plus it would cost a lot more if you pay a shop to do all the work for you. I saved thousands because I did it all myself. As for the 1000hp target, trust me, you won't need it. Its hard enough trying to get traction on the street, let alone with that much power. Anything between 350-400rwkw is more than enough for anyone. If you aim for this figure, its achievable with a mild engine build with gt28rs's plus all the supporting mods. Give me the money and I'll do all the work for ya!!
