tim01customs Posted December 12, 2007 Share Posted December 12, 2007 i have a d16 im doing a complete rebuild and im runing a t3t4 turbo and i dont know what i should do to get enough fuel for it so any ideas about anything would be great thanks (im going to try to run max 20lbs boost) thanks Link to comment Share on other sites More sharing options...
Ben. Posted December 12, 2007 Share Posted December 12, 2007 Hondata..Crome.. Whatever floats your boat. Most of it does the same thing. As for the build aspect of it, you better be putting some new components in there..low compression pistons, stronger rods..shotpeen the crank and all that jibber-jabber. You boost 20psi on a stockblock D-series and you're gonna LOOOOOOVE having to clean up the parts trail you've left behind. Link to comment Share on other sites More sharing options...
cranny Posted December 12, 2007 Share Posted December 12, 2007 you need forged internals , 750cc injectors , and fuel managment. crome is cheap really , and works well. xenocron.com. Link to comment Share on other sites More sharing options...

Flat rate fee for dyno is 300 and the hondata if you supply the ecu is 295 for s200 Link to comment Share on other sites More sharing options...
cranny Posted December 12, 2007 Share Posted December 12, 2007 yeah hondata is pricey , but no doubt one of if not the best. unless you wanna fork out serious dollars for EMS. Link to comment Share on other sites More sharing options...

You boost 20psi on a stockblock D-series and you're gonna LOOOOOOVE having to clean up the parts trail you've left behind. i have debird the block have a forged crank that can hold 650hp eagle H beam rods 8.5.1 pistons medium drade race bearings multilayer head gasket head studs(APR) studs d16cam port polished the head bushinged the stock valve springs and cut the valve guide downe a little fore spring clearance this bumped the valve spring compression about 20lbs so i dont float a valve at max 7500 rpm and i polished my cam and crank i am puting a turbo on it with a T3 63turbine Exhaust side and a T4 50tturbine compressor side and header 3in down pipe highflow cat and out the back. so thats about all ive done so far.

IVhorsemenmotorsports Posted December 16, 2007 Share Posted December 16, 2007 i have debird the block have a forged crank that can hold 650hp eagle H beam rods 8.5.1 pistons medium drade race bearings multilayer head gasket head studs(APR) studs d16cam port polished the head bushinged the stock valve springs and cut the valve guide downe a little fore spring clearance this bumped the valve spring compression about 20lbs so i dont float a valve at max 7500 rpm and i polished my cam and crank i am puting a turbo on it with a T3 63turbine Exhaust side and a T4 50tturbine compressor side and header 3in down pipe highflow cat and out the back. so thats about all ive done so far. chrome would probably be the cheapest but you will still need dyno time. as far as shimmong the valve spring for more pressure did you verify the spring installed height for the valve springs? By shimming it your setting the spring closer to the retainer. You get the extra pressure but run the chance of coil bind. what type of shim did you use and where did you place it? the factory crank is forged and i have seen them personally hold up to 750whp without breaking. Honda parts are good. also remember to put a little more clearance in the piston to wall and the rod bearings if you plan on running a lot of boost. hope that helps Link to comment Share on other sites More sharing options...

cranny Posted December 17, 2007 Share Posted December 17, 2007 cast pistons little more prone to tuning issues and detonation for high ower engines. or let say , noone would use anything but forged for high power engines. do yourself a favor , dont try and hack together a valvetrain please , specially with a newly rebuilt engine. your asking for a dropped valve. litte more clearance most likely hes saying cause of the heat involved in boosted engines. but if your using high silicon forged pistons , they swell and contract less than lower silicon. high silicon are not as strong as low , but low silicon you need extra clearance to allow for the expanding when they heat up , and they burn oil when cold and other little quirks.

The factory honda pistons are the same material and the factory specs on those are .0004-.0016 from the factory manual. Forged pistons are usually .003 depending on the material. As far as the extra clearance, cranny and I are on the same page. Heat! Metal expands with heat especially boosted and running for a long period of time. The extra clearance on the rod bearings is to provide a thicker amount of oil to cushion the rod. The rod bearings actually float on the crankshaft with the oil as a separater. When that flim of oil collaspses then the bearing meets the crank. More clearance use a thicker oil. Link to comment Share on other sites More sharing options...

tim01customs Posted December 20, 2007 Author Share Posted December 20, 2007 did you put that shim under the spring seat or on top of it? it should have went under the spring seat yep i put under the seat. well i got to thinking about what u guys were saying about using a cast piston so i just baught a new set of forged supertech pistons that are 8.8.1 comp i figured they would do the job fore me what do u think about them? also fore fuel i got a great deal on an apexi s-fmu management system i got it fore really like 5$ so i baught it and it was working to so do u think it will do the job for the fuel if im using 450cc injectors.the only thing i dont have for it is the wiring diagram.

The fmu in y opinion is junk unless the vehicle is only boosting 5 psi or below. Spend the money on a management unit. Best to spend more now than twice more later. Good move on the forged pistons. If the apex is a piggyback system i would not use it if you plan to boost more then 8 psi. Piggybacks trick the ecu in order to deliver less or more fuel but in turn the factory ecu alters cam timing when you mess with the fuel adjustment. To get the 450cc to run on the lower range properly you would lean out the mixture and in turn the ecu automatically advances the timing. Boosted cars don't like advanced timing. hope that helps.

solmeistro Posted December 23, 2007 Share Posted December 23, 2007 don't forget about the fuel pump...too big injectors with not enough balls behind the fuel pump will tear it up... i never swapped out cranks in any of my motor rebuilds, the stock crank is more than enough, plus it's fitted to the block nice and neat, i would just make sure to plastigauge the main caps and bearings to be sure about your tourques... also i sleeved my blocks before putting boost behind 'em, unless i was only pushing 7 psi's. hypereutectics are great for all motor purposes, (i.e. cheap, strong, heat reflective properties) but for turbo definetly go forged...

cranny Posted December 23, 2007 Share Posted December 23, 2007 the only time ive ever used an aftermarket crank was a type r engine i built for a guy not long ago , his oem crank was damaged beyond repair , so he bought an eagle crank. Link to comment Share on other sites More sharing options...
