  1. well part of me wanting to get a Z is the fact that i enjoy working on cars...i am looking forward to taking the engine apart and cleaing / freshening up the motor and being able to say that "I built this", not i bought this then droped it in my car.. i am just looking forward to spenidng weekends out in my garrage tearing the car apart and the engine and rebuilding / cleaning eveything for both the car and engine..
  2. nice project..looks like you know what you want from this.. i will be starting a similar project soon.. can't wait... i'll be following this though... good luck
  3. I did search on here and on internet.. i have seen posts talking about p90's pairing it on various heads and modifying them.. i have seen posts about people looking for a specific year p90 head.. based off that it looks like the 83's have that head.. but didn't see a break down of what years came w/ the P90 head on the L28ET
  4. great.. thanks alot.. very informative... i tried looking at garrets page.. but couldn't find that nfo..
  5. so your saying.. stock motor.. stock internals.. megasquirt.. boost controller. and injectors?
  6. well i want this to be my project car.. want to take my time with it and build it right..
  7. so.. if i do my refersher rebuild on the engine.... stock turbo and waste gate.. down pipe with exhaust.. intercooler.. megasquirt.. coil pack, fuel pump and injectors.. get around 250rwhp.. and if that gets boring.. then i can upgrade the turbo
  8. so you recomend that turbo w/ the stock wastegate.. not an external wastegate.... what is the difference between the trim and the a/r?
  9. so i am in the planning stages of my build.. L28ET.. refresher rebuild.. P90 head.. cleaned.. decked.. valve job.. Megasquirt, coil, injectors, fuel pump, intercooler, exhaust.. boost controller so that is the basics of the build.. but the quesiton lies with the turbo.. what turbo / size would be best for this app... i was thinking of pairing with a NA cam, looking for approx 15psi w/ a fast spool.. Stock Turbo T3/T4e .50 trim T4 Halset
  10. Thanks for all the info.. helps me make some choices.. with regards to the overlap w/ the NA cam and stock turbo.. would i be better off going w/ the t3/t4 and the na cam.... i was thinking of going possibly the megasquirt efi.. not sure if it pretains to the turbo L series engines.. but i have read alot of posts about these engines being designed to rev to 7000rpm.. is this doable.. or wantable on a turbo engine? i have seen a few people using the Halset hy35 turbo... how would that rate w/ this application?
  11. yes there is.. and i read through it.. it does give tech info about it.. i just wanted to comparte it to the popular T3/T4.. and get peoples opinions.. http://forums.hybridz.org/showthread.php?t=117018&highlight=Holset+FAQ
  12. Did the search already.. read the posts.. most say similar things.. just that they got one. or what size they are running.. or looking to get.. not too much about efficiency.. and spool times.. i have found posts about max boost..
  13. i did search.. but didn't find to much.. all i know is its a dodge cummings turbo..
  14. What is the story with the Holset turbo's??? I see alot of people on here use them on their Z, but i do not know to much about them.. I really only heard of Garret and Turbonetics... How are they? I was orig looking for a T3/T4 hybrid... how do the holset turbo's rate comparted to them? what size would i want to run on a L28 to achieve around 300rwhp.. and what boos levels? thanks,
  15. Not that i am having any problems.. and not sure if there is anything that can be done about it being the intake and exhaust are on the same side.. but w/ the charge pipe off the turbo and the intake pipe off the intercooler being so close together and almost touching in some applications.. does the heat off the hot pipe transfer to the cold pipe at all? borrowd pic:
  16. OK.. so i am still in the planning stages.. but have a good idea of what i am looking to do and get out of my car... The car will be a 72 240z, w/ an L28ET, P90 head. I am planning on breaking down the motor and just giving it a refresh.. not really building it up.. just refreshing worn old 150K + old parts.. The head i will send out to get cleaned up.. new valves and seals.. and give it a fresh monting surface.. no porting.. I was going to go w/ a MSD igintian and some sort of EFI software.. I was leaning towards a T3/T4 hybrid turbo, w/ a downpipe and 3" exhaust. higher output fuel pump.. larger injectors.. and a new fuel rail.. better plugs, waste gate, BOV, Intercooler, 60mm throttle body OK.. so here is what i want from the car.. This is NOT a daily driver.. though i will occasionally take it to work when its nice out.. This will be my weekend cruiser / toy car w/ the occcasional auto X.. not really a track or drag car at all.. just street fun.. Looking for something around 300rwhp.. was hoping to run 15psi or less.. depends on what i need to reach numbers... and would like power to be there close to 3K rpms.. don't want an NA car w/ 150hp.. then at 5K the boost hits and power doubles.. would like full boost to hit early.. and stay through 6.5k... hope this is realistic.. so.. will the t3/t4 be sufficient.. and is what i am planning good for my expectations.... any suggestions / changes i need to consider to get what i want.
  17. yea i could see that being a problem... i have heard a few with the triplets and they do sound great.. BUT.. as of now.. after reading all i have.. and after what people have been saying to me about the cost and time involved in building a 3.1L and finding the reputable shop.. i think i may change my ways for now.. I still love the 72 240Z, but instead of doing the 3.1l, i think i am going to just go L28ET.... and eventually when i have more time and money down the road.. build a second Z w/ the 3.1L.. but for now.. with my budget. i think the car would be better off and more likley to get finished w/ the L28ET.. figure to get a engine/tranny/ecu setup.. have the engine freshened up / strengthened.... exhaust, intercooler.. and a T3/T4.. I know its very different then my original choice.. but i don't want to start the car.. and either not finish... or have it sit for a very long time.. And with regards to finding a Z enthusiast shop to build and balance the 3.1... i don't think i will be a problem getting a L28 freshened up and strenghtened....
  18. i have a reputable engine shop that i have used in the past that everyone around here raves about.. Not sure if they have worked on 3.1L before.. i plan to ask around here before i get to that point to see if anyone knows of a good shop on long island.. Is there a difference between the 240sx pistons and the truck pistons? last question is about the intake.. how do the tripple carbs rate agains fuel injection? I always though the tripple carb high reving 3.1L would be great.. but wasn't sure if injection would be a better setup. thanks,
  19. Just a quick newb question.. do all of the L6 heads have both the the intake and exhaust on the same side of the head? Are there any X flow heads?
  20. OK, so I have been doing lots or research and reading in getting prepared for my upcoming project... but it appears that the thoughts on this site are different and i was going the wrong way... So here's the plan: 72 240z, 3.1L I have access to the diesel crank so that made my decision on this project easy. I know this is not an easy projcect and there is alot involved, and i know its going to take alot of time and money to be done right. so i know i have to start of with the L28 engine, LD28 crank, 240sx pistons, and i have head about boring it 3mm over bore, and getting the 9mm connecting rods from the 240. from what i have seen there are lots of head combo's out there to choose from.. so with regards to the starting point.. any recomendations for the base engine to start with.. will any L28 do? thanks
  21. well i guess since the everyone has the same thought the sonic testing wouln't be necessary.. so the 42 block is on the L28? basically my plan is to go 3.1 w/ 10:1 or so compression.. any recomendations?
  22. There were non turbo cars.. and they used the N42 block.. and through my research. they say that the F54 block being the turbo block had reinforcements between the cylinders...
