The story is...about 3 yrs ago when i was racing my brother on the highway my car die and won't start back up. I towed it home and was looking to get it fix but it broken into and lots of stuff was stolen and it sat since. So about a couple of weeks ago when i was able to get the car out and started to work on it, it finally started and it looks like i would need a rebuilt. A lot of smokes are coming out from the exhaust as you guys can see from the photo.

Now my question is...With all my mods below, what porting would be enough for me to make 550whp+ and who would you guys recommend me sending my engine to, thanks a lot.

Power FC
4" exhaust
ID 1000 and 2000
Dual supra fuel pump with 6 lines feed and return
Blitz boost controller
vmount set up
hks twin
HKS T51r Turbo
AEM water/Meth injection

You could make 550rwhp on stock ports with that turbo. It really depends on what fuel you want to run and your preference level of street ability. What is considered streetable to one person may be insanely obnoxious to the next.

If I were you, I'd send the car to Speed1, they are in Lenhartsville, PA and know their ****. That... and they aren't out to trade substandard work for stupidly high prices.

Thanks I was thinking that too, i've been there a couple of times to see Dave and he was the one who tune my car too. Great i guess i'll stay with half bridge if i can make that power or more. Thanks a lot.

Just another curious question. I drove it around last night and it seems to be driving ok and not losing any power, so with that said would my turbo be causing the smokes as well? or it's really the engine?

Honestly I'm not going to even pretend to be able to diagnose it from here

I'd give Dave a call, let him know what's going on, and see about getting a compression test before you start tearing everything apart.

I just did a half bridge motor that put down 534 to the wheels with a much smaller turbo so your goals are well within reach. I did another one that was in the 560whp range earlier this year as well. We've had a 500whp shop car for 5 years plus on the same engine. It looks like you already have a pretty solid lists of mods. I would add a second supra pump or a single larger pump and larger feed if you already haven't done so, and possibly a more powerful ecu like a Haltech PS1000 and IGN-1A ignition coils if budget allows. as for the motor itself, you are going to need a solid build with good parts. All seals should be new and clearancing becomes even more important. I recommend studs at anything over 500rwhp. Its debatable but balancing the rotating assembly and side clearancing the rotors is also a good idea at this power level. Its going to come down to the setup and tune. A lot of people try to venture into this power level and fail because of small mistakes and taking advice from the wrong people. Before you pull anything apart the first thing I would do is determine where the motor stands with a rotary compression test. You might have something silly going on and the motor might not even be a problem. Below are two dyno sheets from recent builds I did for customers.

Thanks IRP, I did an oil leak test yesterday with the oil line remove from the turbo and drain into the oil filler. When i did this it seems to smoke a lot less, well during cold first start with this remove it hardly smoke at all. So i would think it might be my turbo oring that's causing the smokes as of now and not the engine. The reason being is that when i took the car for a quick spins it seems to respond well all the way to 6k rpm, would a bad motor be able to do this? Also if my turbo is bad would IRP be able to rebuild it for me? It is the early version of the HKS T51r KAI journal bearing. Thanks

If you took the turbo out of the equation and it smoked less, then that is usually a good sign. does the turbo spin freely? I'll get a price to rebuilt it shortly. Have you compression tested the motor yet? If you are getting break up/hesitation at 6k but it seems fine most likely you have an ignition or fueling issue. I would do the compression test first to rule out the motor before wasting time and money doing anything else.
