heres a pic of vvt solenoid with its red coloured plug , right hand side front of engine just near fuel press reg

SURE CAM can regrind stock cams , they are fairly mild because stock cams cant be ground much . He does an inlet with 255 degrees duration and 8.2 mm lift exhaust 258 " " " " 8.2 " " stock cams are 240 degrees duration with 7. 8 mm lift $ 170 per cam to regrind ph 02 4736 1742

got it at a newsagent on saturdee

Yep , just got my copy of ZOOM issue 103 , and there it is . Good stuff .

AH tell me about it . Have spent many hours unravelling harness . Thought i had it right , then discovered i had chopped out 16 wires too many that go to the transmission ecu , a big BUGGA . Have had a lot of help from NICO forum in sorting that prob out .

Spent many hrs on saturday , disecting the harness . had pulled out all engine bay harness and in car harness . Massive amounts of wiring . Found a total of 6 computers . Only using 2 of the computers , engine management and auto trans . Believe i have all the wiring i need after chopping out one big box full of surplus wiring and electricals .

YES alloy sump block and heads

Mods will be limited to extractors ( home built ) , cams if i can get the stock cams ground , malpassi fuel pressure reg , Apexi safc 2 and a decent air intake . I will be doing the installation myself and am going to tackle the wiring up too . I will be using the auto box the engine come with , cheapest and easiest option for now . Fitting an rb25det box would be a good option , but but would cost more than my whole half cut by the time its fitted . The red car is not for sale yet, as it will still be my daily driver until i finish the blue cars conversion . Hoewever will be selling the rb30de engine at a latter date , maybe towards the end of the year . Its not a priority but it would be nice to have it all done for a total of less than $ 5000 ( including purchase of car and half cut ) . 150 Mph + for less than $ 5000 , i like .

OK . Here is a pic of the wagon i raced this year at Lake Gairdner speed trials . Was running a RB30DE . Best average speed over 1 mile was 141 .187 MPH ( 227.21 kmh ) . I saw 152 MPH ( tacho reading ) at the end of one run . Engine basically stock with 370 cc injectors , extractors and 2 x rb25 throttle bodies , apexi safc 2 , and thats it . Standard cams and head .... NON TURBO

This is the plan . Build an R31 with a VH41DE ( Nissan V8 4100cc ) Heres what i have . I bought a VH41DE half cut for $ 1750 delivered Bought the wagon for off ebay for $ 900 . It has a mint body . Replaced the diff ( $ 80 ) , replaced leaky water pump ( had a spare ) . Got it registered 3 weeks ago . I plan to keep it looking as stock as possible , even down to the hubcaps . Am only interested in going fast in a straight line , drags and on the salt flat . Deliberately chose the 4100 cc engine to suit the class ( F = 3000 - 4300 cc ) i want to run at the salt lake speed trials .

This is whats happening . About 6 mths ago i bought a mint 89 gx wagon off ebay for $ 900 . The plan was to tranfer the drive train from the rusty red car into it . As i wanted more power out of the rb30de , i did some sums and figured i could get more power by putting in a Nissan V8 . So i have bought a Nissan vh41de half cut for $ 1700 . It was going to cost me at least $ 2000 for a pair of rb25 cams and an aftermarket ecu . Plus i can sell off the rb30de and manual box and all the other goodies for more than the cost of the half cut . Bsaically its going to cost me nothing to go faster , just a lot of time and a few headaches i spose . End result will be 89 gx wagon with vh41de , hopefully by about October . Red wagon will go to heaven ( just dont like dead cars hanging around )

sorry for delay . No havent had it dynoed yet , probably wont , car will only be on road a few more months before it goes to Skyline heaven .

BADR33 , have you got a time for your car on the 1/4 mile yet .

pm sent

what was the price of them , i had to reuse old gaskets

I calculated i have10.5 - 1 compression . I use stock RB25DE pistons which sit about .050" lower than rb30s . RB25DEs pistons have taller dome tho . To get around 11-1 + compression , deck the rb30 block .050" so that pistons outer edge sit higher

THIS IS WHAT I DO WHEN RACING 3rd and 2nd pics are what i used at drags ( 14 .4 @ 95 mph ) 1st and 3rd pics are what i used at sal lake speed trials ( 141 mph average at one point taching 152 mph )

OR ONE I THESE . I made this one with 2 x rb25 throttle bodies , plenty of air and more torque than short runners .

Thanks for the info . YEP i bought the half cut yesterday , being delivered this morn . I did a few measurements before and it looks ok .

I,m going to look at a vh41de half cut today .It will be for my blue r31 wagon . Prefer the 4.1 ltr so that i can race in " E " engine size class at the salt lake ( 184 - 260 c.i. or 3000-4260 cc ) . So maybe picking someones brain soon , but wont be a pest .

I tried to do that but my 5 yr old dinosaur puter and scanner wouldnt . I could fax a copy if you want .

AHA got that wrong . i dug out that magazine i quoted from HPI 48 . They tested a r3 4 door auto RB25DE and base figure was 105 rwkw . They played with timing , air intake and tried a fuel cut defender and got it up to 121 rwkw .

standard rb25 de injectors are 270 cc

i been thinkin about getting it dynoed for the last 2 years , cant rush these things . the safc tuning kind of guessing . As i run a rb25de ecu and i have an engine 20 % bigger , i justed figured it needed at least 20 % more fuel plus a bit more for having more air via the 2 x throttle bodies and extractors . From idle to around 3000 rpm it has an extra 10 up to 30 % at high throttle 3000rpm and above 30 % . low throttle settings are all set at 5% below this

GDAY . Those figures seem ok to me . High performance imports magazine got close to that figure with an r33 rb25det after a good tune and a few minor mods . My engine is very close to what you have , and my times at the drags ( 1/4 mile ) are near identical to what a stock r33 rb25det should do . The difference in my engine is 370 cc rb25det injectors , twin throttle bodies and i run an apexi safc 2 .
