What's up peoples!

Just bolted on a turbo over the weekend onto my 99 GSR and I need help tuning the turbo. Here are the goodies I put on.

Current Boost - 7psi
Turbo - Garrett t3/t4 ballbearing
Wasegate - Turbonetics.
Blowoff - HKS Race Spec
Intercooler - Apex-i full front
Fuel Pump - MSD
Boost dependent Fuel Regulator - Vortech
Boost and Air Fuel Gauges - R1
Manifold - Revhard

From what I understand I should retard the timing 1 degree per lb. of boost correct? Also, what other tips can you give me to get the most from my turbo? Does anyone know of any good turbo tuning sites?

Thanks!

Look up Arturbo, he's a moderator and a turbo guru.

 

get that thing to a dyno, it's a must to get the most out of that setup.

 

retarding the timing that much is completely unnecessary. Retard it about 2-3 degrees. What ratio is your FMU? 12:1? Personally, if i don't get a standalone for a while (which im not) after i get my turbo, im going to run 440s and an SMC. I've heard it's a great and the transition into boost is smooth. I would never run an FMU. To me, they seem unreliable and although a great concept (coorect fuel per psi of boost), the fuel psi will run way to high. I just don't like the fact that some turbo kits even supply you with a 12:1 fmu.

It's all about the poor man's hondata (afc hack, or smc mod) until you can afford a standalone and a couple hours of dyno time!

good luck and happy boosting

Thanks for the replies fellas, I bought some dyno time at a shop by my house so I'll let you know how it turns out!

 

Ask the same question in the FI forum.

 

Welcome to the Dark-Side.

 

Thanks Wreath, lol.

 

is your MSD fuel pump inline? if so, then good.

theres nothing wrong with using a fmu and inline as long as you dont boost that much. the more you boost, the higher your fuel pressure will be... and your injectors might seize or your fuel lines will give way.

you can try using the AFC hack method. the money you spend on a AFC is already a little over half of how much a Hondata system costs. you will end up needing new injectors either way... so you might as well get new injectors and Hondata.

you can use the SMC method, but its limited to what it can do as well. if you read up in the forced induction forum... a few users did not like it because of its limited adjustibility. dont waste your money and do it the right way the first time. stick to your fmu and inline... but take it to the dyno to see where you stand.

i dyno'd my car with the fmu, stock injectors, and inline fuel pump fuel management and had a good air/fuel ratio til 4500+ rpms. after that... it would get real rich. if all you want to do is buy a AFC... you can lean out the fuel when it starts to go rich... and tune it for more power.

cliff notes:
-tune out richness with AFC $300
-do the AFC hack with new injectors $300+$315
-hondata and new injectors $475+$315
-smc and injectors $100+$315

if you get some used DSM 450cc injectors... they run around $50. save alot of money if you go that route, too.

i rather go with the hondata and new injectors. if you cant afford it right now.. save up and do it right. youll be fine with the fmu and inline for now.

Good post dlplayboy, thanks! and yes, my MSD is in-line.
