Administrators gav240z Posted November 11, 2011 Administrators Share Posted November 11, 2011 well big weekend in the shed some pics for the l28t people out there Fantastic looking engine good work Pete. A few questions? - What kind of harmonic balancer is that? - At what RPM do you think this set up will make full boost? - What type of ECU will control it? - Finally what kind of gearbox will go behind it?

peter mc Posted November 11, 2011 Author Share Posted November 11, 2011 Hi Gav the balancer is a BHJ from the USA Rebello sell them, nice part boost will be about 20psi and it should see it all by 4000 and peek power will be 7000 ECU is a Autronic the ECU will be tuned in WA by Aaron and Aaron has converted a VG30 box to go behind it, so he wont have any problems this thing will look grate when its finished the exhaust manifold will be hpc and the inlet may be as well and all hoses are brade Quote Link to comment Share on other sites More sharing options...
Vindicare Posted November 12, 2011 Share Posted November 12, 2011 The BHJ damper can be purchased direct from BHJ Dynamics. Similar pricing to the ATI one. Autronic SMC is the ECU, 500R CDI w/ M&W coils(Currently running on the L24et in the car) Gearbag is a RB25t box -> 300zx bell-housing -> Austin Hoke adapter, trying to figure out clutch now, calling Jim Berry on monday I think. So excited to get this back and in the car Then I can start breaking stuff and suffer the wrath of the other half Quote Link to comment Share on other sites More sharing options...
PZG302 Posted November 12, 2011 Share Posted November 12, 2011 The BHJ balances are a nice bit of kit. When the one I ran was fitted it made a huge difference to how the engine revved, I was changing gears 50k or so metres earlier at Lakeside with no other changes than than throwing the standard balancer in the bin.

Agno Posted November 13, 2011 Share Posted November 13, 2011 Very nice with the mounting of the LS1 coils! Quote Link to comment Share on other sites More sharing options...
Vindicare Posted November 13, 2011 Share Posted November 13, 2011 haha, yeah that cover is Peter's, Put on something to keep the dust out My coild will be mounted to the inner fender most likely Quote Link to comment Share on other sites More sharing options...

Baja Burley Posted February 26, 2012 Share Posted February 26, 2012 Any updates on this monster yet? Has to be close to turnkey now! Quote Link to comment Share on other sites More sharing options...
Vindicare Posted February 26, 2012 Share Posted February 26, 2012 not really, we had some trouble with sourcing a suitable intake, now waiting for a Lonewolf intake to be made, once peter has it he's gonna finish the small things, then send it back to me. Unfortunately i'll be moving soon so it wont be going in straight away. Will be nice to have it back just to stare at, waste some moments contemplating how awesome it will be Quote Link to comment Share on other sites More sharing options...
DaMuffinman Posted March 15, 2012 Share Posted March 15, 2012 Any chance u would like to tell us what clearances ur using on the bottom end? Also im thinking of doing the same setup but with a set of 2860-7 garrets I've got laying around. the head I've got is an e88. Is this still useable or should i just look for a p90? Thanks. ps the exhaust manifold looks like a work of art. And is there any reason u didn't go multi tb ? Quote Link to comment Share on other sites More sharing options...
peter mc Posted March 15, 2012 Author Share Posted March 15, 2012 well there are diffrent types of E88s 240 type and late l24e .... both have small chambers the Late one has a really nice chamber for NA but is way to small for a turbo set up and the and 240z one is no good for the job ... p90 is the best for the job by far, 53cc makes it perfect for turbo and its design lets you run more timing than any other Nissan head as for the itb yer they work , but make it lots harder to tune and cost lots more , is there a hp benefit no, is there better throttle responce yes ,,,, is it worth the hassle no Quote Link to comment Share on other sites More sharing options...
Vindicare Posted March 15, 2012 Share Posted March 15, 2012 My current engine is a L24 with a E88, but what e88 i couldn't tell you. I don't really know much at all about the current set-up, but it works? I've never pushed it, currently makes 148rwhpat 13psi spike levelling out at 11 psi. It's running all the gear off a L20 turbo engine, so would be quite restrictive on the intake side, which would explain the higher boost required for not too much power? On the Autronic compression is listed as 8:1, the engine was rebuilt and owner said it was given oversize pistons, possibly put in a dished piston maybe? Owner made it sound like he used the original head as he mention it being drilled to suit the injectors. Matching numbers block so that would make it a 1973 e88? All speculation on my part, I did not know as much about engines or Datsun's when I purchased the car, but I don't regret my purchase Quote Link to comment Share on other sites More sharing options...

Vindicare Posted March 16, 2012 Share Posted March 16, 2012 Lol been alive like 9 years now. Takes a hard beating by myself almost daily. It definatelt works just not enough power Quote Link to comment Share on other sites More sharing options...

d3c0y Posted March 16, 2012 Share Posted March 16, 2012 An L28 with triple carbs will make that much power for a lot less effort. Quote Link to comment Share on other sites More sharing options...
peter mc Posted March 16, 2012 Author Share Posted March 16, 2012 yep thats my point a good L28 with injection makes 250 hp atw 0 boost Quote Link to comment Share on other sites More sharing options...
DaMuffinman Posted March 16, 2012 Share Posted March 16, 2012 The l28 in my z is making 215atw kw on 15 psi on an e88 head. but im looking to more around the 260kw area. its not running electronic ignition yet . what sorta gains are to be had? any other options before i start pulling the head off and going for a p90?

peter mc Posted March 17, 2012 Author Share Posted March 17, 2012 Control over the ignition is the most inportant part of a turbo setup . the most inportant by far , timing is all inportant to making the motor last and make power . for eg a L28 NA needs 28 to 32 deg at 10.to 1 comp to make it all work right . now if you don't have enough timing it will not make power and will feel flat and boring retarded , and if you have to much it will ping and blow head gaskets and crack ring lands and wreck the engine advanced so with a turbo engine like yours you say you have 15psi with a t3 turbo like stock one , off boost the engine needs 30deg to run nice at 3500 rpm and above that's off boost , now add boost . now we need to remove timing or the engine will ping and die so for every psi we need to remove timing how much we remove depends on lots of things every engine is diffrent and small turbos are the worst, req more timing to be pulled out fast as they make boost fast . so your L28 with 15psi t3 will need at a guess 17 deg removed with that head you have .. now as a tuner if i have to remove more than 12 deg timing i now the setup is not as good as it should be and id be looking at the head , and air temps or a restriction in the system , you no there is a problem when the boost is not making more hp and your removing more timing per psi to stop pinging .

DaMuffinman Posted March 18, 2012 Share Posted March 18, 2012 thanks for the advice. it has cleared alot of things up for me. Quote Link to comment Share on other sites More sharing options...
CH105 Posted March 22, 2012 Share Posted March 22, 2012 I'm really enjoying this thread, looking forward to further updates. I've not seen the girdle before, is that something you supply Peter? Really like the exhaust manifold, what turbo fitting does it take? Quote Link to comment Share on other sites More sharing options...
Vindicare Posted March 29, 2012 Share Posted March 29, 2012 Girdle is from amember on here. Maanifold is a t4 flange however iam using a t3 t4 adapter. Intake will arrive to peter soon, so the engine willbe fully together . Then just gotta save the rest of money needed to install. Quote Link to comment Share on other sites More sharing options...
peter mc Posted April 19, 2012 Author Share Posted April 19, 2012 some pics of the new inlet from the US and the exhaust manifold now with the wgate on . more pics tomorrow off the head with the new water mods , iv striped the hole thing as it been sitting not finished so i wonted to make shore its all as good as it should be Quote Link to comment Share on other sites More sharing options...
handsandwhich Posted April 19, 2012 Share Posted April 19, 2012 Pete, you know I love shiny polished things and that manifold needs the bling factor added. Owner should seriously consider polishing it up before installation. Quote Link to comment Share on other sites More sharing options...
peter mc Posted April 19, 2012 Author Share Posted April 19, 2012 your not wrong mate the finish is not as good as it should be ,,, like most things that come from the US now there crap , i was thinking id send it over to hpc . after i finish it so it works , ,, it needs about 4 hours of time to weld up and fix all the crap welds and weld a peace of ally to the bottom and tap some holes in it for the vacuum pickups . just a peace of crap the way it came from the US Quote Link to comment Share on other sites More sharing options...
