  1. agreed... a smarter approach would be a peice of fishing line on a weight
  2. I can't go into full details as the design is a collaboration. But basically the throttles are yoked together using a purpose built endplate and linkage. The throttle cable is on the firewall (see me grabbing it in the video). There are multiple approaches to the throttle issue, all of them requiring some fabrication. I chose this option not because it was technically the best but it was definitely the cleanest. EFI is meant to be clean without springs and linkages going everywhere like on carbs so it kept it simple accordingly. -pete
  3. Some crappy iphone photos as teaser ...and a teaser video thanks to my housemate I'm still doing alot of tuning on this setup but its coming along nicely. -pete
  4. Take the spark plug out and fill the cylinder with fluid at BDC untill it is about to flow out the plug hole. then multiply the volume used by 6 after subtracting ~20 ml for gasket and partial CC volume. Then agian... *I* wouldn't do that...
  5. So why can't the OP swap his injectors? I mean... it would probably be prudent for us to ask why do you think you need bigger injectors? But aside from running rich as dogs breath because of choosing the wrong injectors (bigger ain't better) it seemed you were implying there was a practical limitation to the ECU driving alternative injectors. zedman... what are the full details of your motor (head/block/turbo/ecu/FP and pressure) and what evidence do you have to suggest you need aftermarket injectors (AFR's detontation or anedotes)? Cheers, -pete *edit* It sounds like snow would be more qualified to answer this question an I but I don't think stock L28et injectors should not be a hindrance to you running that HP.
  6. Question: how is it acceptable to increase fuel pressure but not acceptable to increase injector size? I've never bothered to mess around with the stock ecu as aftermarket units are much more tunable but out of curiosity it seems the net effect would be the same. A greater pressure differential = more flow right? So why would it be okay to run the stock injector at greater than stock flow rates but not an aftermarket injector of comparable flow ASSUMING you correct to circuit resistance appropriately? -pete
  7. its a really big air conditioner for the inside of your engine.
  8. Stick with it. Wiring appears overhwelming at first but after a while becomes second nature. The first time I did wiring work I felt up to my neck too... it didnt take too long before the idea of making a new loom in a day off is as simple and mundane as doing the laundry -pete
  9. alas... it's true: this is not one of the fabled 3.3litre seven cylinder L-series engines
  10. have this running... i'll try and get a video soonish... GTR itb's are 45mm. The induction noise is angry -pete
  11. Pics should work. FYI. I don't think it can be done neatly without a fair amount of machining. I've seen it done before but very messily and injector mounting is a bit of bother - custom fuel rail etc was required. -pete
  12. Hi all, I thought it'd post of some pictures of my "homemade" itb install. It was an idea my brother and i had some time ago about using gtr throttle bodies on a converted mikuni/weber manifold. The thought being i'm too young for carburetors, love efi and am too poor for extrudeabody prices. all up the setup cost ~$500 in parts and machining but requires alot of labour, planning and generous machining time. it has come together nicely me thinks and i thought i'd share some install photos its been ages since i posted here! i hope everyone is still having fun. -pete
  13. ...why on earth is he still running injector fans?
  14. Tony, To my understanding the 77' 330 nissan cedric had no turbo option... ? Even in japan I've seen very few turbo cedrics, some y30s i think had a turbo option? Cheers, Pete
  15. I couldn't figure out the policy on 330's when I was there... I went to the JCCA meet in tokyo this year and saw just one 330 in boring paint and stock trim... I was wondering where all the cedrics were... (mind you there was heaps of 60's models)
  16. I think you are getting off track: Your car ran before? if yes lets forget about compression testing for now. Deal with it later if you cannot start using a normal troubleshoot and you suspect you have damaged the valves. Describe exactly what you did to get from a running car to a not-running car, did you remove the head, change the cam, adjust the valvetrain etc etc.??? more information is better. Then work through it. 1. Determine the cam position is correct BEFORE TURNING THE ENGINE ONE INCH!!! 2. Determine you have correct spark and at the correct time using a timing light on cyl#1 at ~10BTDC, if not either your distributor position is wrong or your dizzy shaft. if you remove the dizzy shaft dont forget to reprime your oil pump before reinstallation. 3. check your Firing order is correct 4. now start looking for fuel, disconnect the distributor and crank the engine a few cycles... are the plugs wet? if not you have an EFI issue. Double check your injector firing by using a screwdriver to listen to injector pulses (place one end on the injector, one on your ear and crank listening for "click click" 5. If EFI is to blame search for loose connections, poorly installed connectors etc. 6. FAILING ALL THIS you may need to do a proper compression test and determine if you have some busted or bent valves... Cheers, -pete
  17. no... if they are a different part/size of course the answer is no. you cant swap in a turbo onto a NA ecu just like you cant put big injectors on an ecu that doesnt have the ability to modulate its output signals based on exaust gases etc. Tony was saying you COULD just pput them on an run pig rich... it will "run", but you might need to clean the spark plugs every 10km by hand and you power will be stuffed et-cetera. dont just throw anything that fits on, use the right part. *double facepalm* -pete p.s. & FYI I have a JDM L20e and the injectors are a cream colour.
  18. Pete me pete? I don't recall getting that missed call... if so i was probably at the hospital and in lab and forgot to call back... sorry!! next visit? I'll have plenty to show off by then.
  19. If you go in this direction I still have the electric dizzy from the l24 we picked up. It should be yours anyway... (?) -pete
  20. I recently had a discussion with a fellow on a local forum who was looking into running an n47 with a tongue down the exhaust after hogging it out. I wonder how it'll work out....? (mark: itb's are ready for welding... if i cant find some bloody time during a weekday to drop them off) so anyhow... any insight into the logic of running the two different heads on the same car?
  21. ... what size is that intake valve? thats interesting... sure it wasnt a swap/replacement? every mr30 i've encountered, which isnt heaps, has had the e88 casting.
  22. As i said, the information out there doesnt seem to be very intensive, so any discussion is good I tend to agree with you on all 3 points; i think these would make ripper heads for a high compression stroker etc due to the small chamber size... I'm exploiting one of these for a turbo build with std. 35mm ex. and 44mm in.(OS in this head) valves. I particularly like the look of the spark plug region in the second head... it looks to be nice and smooth ... and the longer valve length was the seller for me over the p90... I still have considerable work to do before this is a running engine so i won't be able to contribute any numerical evidence at this point in time Both heads seem to have mildly different exaust valve profiles to the nissan stamped ones I've pulled from a earlier open chamber e88... its possible theses were both PO fitted or nissan may have updated the exhaust valve somewhere along the line (?) the later valves have no identifiying markings. -Peter
  23. I'm probably pushing my luck asking which version of the e88 you are using on that car and what attributes of the cast led to the choice of the cast over others? (compression, flow etc?) (Still in korea? How is it? I'm envious, I've never been but was hoping to drop over when I visit japan again at the end of the year) -pete
  24. So I've been putting off doing this for a while... I've noticed that there seems to be a void in information on late-model e88 heads for l-series engines (probably due to the fact they were'nt delivered in the US). I thought I'd open some discussion on these heads before contributing to the heads sticky. I've noticed at least two different casts for late-model e88 heads found in australia on l24e's fitted to mr30 skylines. Both later e88's are fitted with internally oiled A cams and solid lifters. They have closed combustion chambers and fuel injector notches (machined, not cast like p90's). Both have 35mm intake ports and "square" type exaust ports. Both has 42mm intake and 35mm exaust valves. I'll refer to two different castings as "cast-a" and "cast-b". Cast-a: has vertically cast lines on all unmachined surfaces excluding the CC's much like those seen on the unidentified head on the cylinder head types sticky. Has "N42 E88" cast into the thermostat coolant outlet floor. Has a tall, well pronounced boss protruding into the CC for the spark plug... (my photos dont show this too well as I was in the process of smoothing this out and dont have a spare head of this casting). The quench pad ends in a smooth transition to the combustion chamber Cast-b: does not have the cast lines nor the "n42 e88" coolant passage casting. The spark plug boss is significantly smoother than the other casting and the quench pad ends in a overhanging lip that as seen on the y70 post made by ozconnection. I have not CC'd the heads and do not have the precise equipment to, i cant give it a stab using agricultural methods but given the "a-cast" has allready been machined and modified slightly i doubt this would prove a productive exercise. Here are some photos of the combustion chambers... you can't pick up the differences too well but they are definately there... also i realised i should have taken both images from the same cylinder... sorry about that... i'll edit it later when i can take another photo "Cast-a": "Cast-b": I have some opinions on the potential applications of these heads and they do see some use amongst L-series builders in Aust. but information is limited and i'd love to hear some open discussion on these heads Cheers! -pete
  25. D: I hear what you're saying... its a pretty convincing illusion on the intake/exhaust side of the CC... i'm really not sold on this one way or the other... i'd like to see a clean pic
