question...... why stoke a motor that you want to drift with? a bigger stroke means u can't rev it out to a big rev limiter.... you want to drift with a stoked vg??? u do know you're going to hang off that limiter 90% of the time right? keep it within stock spec, build it strong and then sit on that limiter mate. u know u want to!
Second. The track car is a destroked wet sleeve engine. I went for a larger bore, but shorter stroke. After doing this though, I probably would have just done a forged rebuild as it too much for the car :cough:: driver, actually). What he is proposing could work, but like I found it costs.... lots. Even if you do most of it your self. Don't foorget you need to may sure you heads are machine to match the block and you will need to have a custom head gasket made too. Also you have to bore to the correct depth (well I did, you may be safe at the 97 mm piston) as you may impact with the oil gallery. You have been warned. The piston to rod length may be an issue, as drz400y noted. But i think that it should be resolved in the crank balancing by the kit suppliers. But if it creates harmonics...well it ain't going to work. (well maybe once) I have already written to Dave (Driftspec), I think the major concern would be the pistons increased velocity, and the air attempted to be drawn through the head. Also that addition rod throw will need metal removed as well so it might start causing block flex. A lot of unknowns here. But this is what pushing the tech boundaries about. You have my support, what's the worst that can happen?
if this is track only why waste the time with E85 im have been running methenol in my vg it's better for tunning and it's cheaper im paying $200 for 200lt only down fall with both E85 and methenol is you have to drain the fuel system after every use.
Damn thats pretty cheap. Dont know a whole lot about methanol injection on the VG. What physical modifications need to be made to run meth?? Suppose I should just do a search, but how is yours set up?? Cheers
You need the ability to run 2.8-3 times the amount of fuel you run on petrol , so depending on power level , more than likely two fuel pumps , fuel line upgrade , bigger injectors . It does come with a bit of maintenance , (But it is so much better than petrol C16 ect ) You also have a 10% window with methanol , You can be 10 % rich without killing power .
yeah but if your looking at running 1000cc injectors why not just the whole way and get 1600cc we used 2 pumps 2 regs etc and we have ended up cutting it back to all single lines and pumps 6 x 1600cc injectors is more than enough we made 700hP on 6
No pix just yet. Got an old block(not reusable) that we're doing a few tests on. No drama's yet. Now I need to find a usable block to start preping for the sleeves. Just calculating the spec's of the sleeve's we will have to run as no one is selling a kit to suite this type of build. Once we know the exact specification needed. Will be ordering the custom sleeve's and commencing the build of the bottom end. Am aware of guys running pistons with a wider diameter then the 97mm i have, with custom sleeves of course. So its all looking possible at this stage. Sorry to leave you all hanging, but his build is going to take me some time to get together. quite a few $$$ too. Have taken some of the above mentioned advice into consideration and am now leaning towards not dropping this engine into the competition drift car. But instead into a show finish /promo car / dyno loving / cruiser, Z32 of course. Undecided yet. Along the way we will be recording how it all comes together just in case any of you would like to travel this road in the future. Now As Im sure you are all aware, drift cars get quite a work out. N being that the Zed I have atm is a track only competition drift car, it needs to be realiable. As in not miss a meet throughout the season. If at one event we blow an engine and like to have a spare ready to go for the next event without spending big bucks every time(sticking to off the shelf gear) So I suppose the deciding factor which at this stage is still unknown is how much this build will end up costing. Will keep you all posted.
bit of a waste making a 3.4 ltr drift 300zx, could rip it up in a stock motor with bolt on turbos.. leave the 3.4 for something special, constant high rev's will break it, just a matter of time imo.
Decided on the cam followers yet? I've decided to stay with stock hydraulics, keep the revs under 8000. For a full on 8000+ race motor solids with the appropriate cams would be better.
