So to make a long story short i spun a bearing in my stock 98 ITR and decided to rebuild for a turbo set-up. Thought id put up a post of my build to see what you guys think and whether or not my goals will be attainable. Looking for 350whp anything more will be great. It will be mainly a street car an occasionally tracked. So here is some info on my build let me know what you think....

98 ITR Head:

Skunk 2 Valves
Skunk 2 Springs and Retainers
ITR cams and gears
Victor X Intake Manifold

LS Block:

81.5mm Bore
Endyne Forged Pistons- 9.5:1.0
Eagle H-Beam Rods
ACL Bearings
Stock LS crank
ARP Head Studs

Turbo Kit:

t3/t4 57 trim turbonetics turbo
log manifold
front mount intercooler
HKS ssqv BOV
38mm Wastegate
3" exhaust
750cc injectors
skunk 2 fuel rail
255 Walbro Fuel Pump

I have Neptune for engine management but im thinking of going with Hondata s300. Anyone have any suggestions for which one i should go with. Also considering of upgrading the manifold to a sheepey built mini-ram with a 44mm wastegate.

Thanks for looking

 

Should be able to make 350 no problem.

I have stock LS that made 348whp with a Garrett "57 trim"

 

I can cosign. My relatively stock ls vtec on e85 made 350 no sweat. Im sure it will be a breeze for you

 

you are gonna need a map sensor

 

I agree 350 shouldn't be a problem at all with that setup

 

Thanks for the comments guys.....so by the sounds of it 375 might be attainable lol

 

Map sensor is on the list!

 

375 would be the upper limit of the turbo.

 

Making just under 400whp right now on bone stock gsr motor with a 57 trim. This is with E85 on 16 pounds of boost

350 is very attainable on that turbo

 

Thanks for the comments guys. Anyone have a preference of Neptune or Hondata. I would like Hondata but already have the Neptune and wondering if it would be worth it spending the extra money for s300?

 

I like Hondata personally

 

If you got it already, use it. No advantage really at this stage in your build (or for most future stages either).

 

Neptune... if I were insistent on using a stock ecu tuning solution.

I prefer something like an AEM ems at minimum... much more user friendly and does more.. but it all depends on what sort of engine management solutions your particular build requires.

 

Cold starts suck on an aem ecu tho

 

I've never seen an AEM equipped car with a proper idle air valve have issues with cold starts

You also have to adjust cold start enrichment, temperature compensation, etc.

Can't just toss a map in the ecu and crank it in the middle of winter.. won't work

Most chipped Honda ECU softwares let the stock programming control cold starts, the software just scales those tables for changes in injector sizing.
