Vince, I was leaning towards the Stage II vs Stage III based upon some of the feedback I was reading about guys having a hard time building boost on big ported heads.

Has anyone else heard of this?

I will post up pictures as soon as I have the turbo in hand. I have been told that physicaly it is not much larger than the 76GTS.... so we will see!

I have not heard of this and I would think the heads would have to be messed up themselves to have problems building boost. Just look around at the big cubed guys and see what valves they are running. That should help you with your answer..

Due to cost limitations... I know I keep saying it... and I know its an oxymoron but this is a "Budget, FI, Big HP build"

Erik builds great motors and his prices are good too. It just made sense for me to go 408.

UPDATE* Almost everything is in the Mail... I have enlisted Scott's help also at PT Motorsports and we are all going to knock out allot of this build this comming weekend.

I went with 96lb injectors like many of you suggested... and going to do the dual Walbro 255's intank (Sumping a plastic tank just seems too iffy)

My whole suspension setup is UMI now *Cough* <plug> from K-member and A-arms all the way back to panhard.

TH400 Trans setup arrives this Friday...

Turbo shipped today...

Engine is done or will be done this week (gotta get in touch with Erik)...

Its all comming together... Turbo delay has taken its toll.. I have paid in full (god I hope so).

looks like it coming together then longranger4u!

how much do you think the 427 would be over the 408?? (hint tell us how much the 408 set you back!!!)

thanks Chris.

PS. only being cheeky! tell me where to go if you dont want to tell the price! i understand

Another thing is the higher the pressure you run the less the fuel pump will flow so I would just get a converter and run like 75-96s right away and be done with it.

I think smokinhawk had some pics of his 99+ dual 255 setup at one time, it will just take some fabricating. Plus you will have to run at least 1/2 tank of gas all the time. That doesnt matter since I have to have to have this Nasty tank nearly full all the time..
Whats wrong with your setup that you have to have it full all the time? thats BS.

Buying my turbo from another board member today as well! PT-88 here we go!

Talked to Erik and my 408 will be done sometime this week, going to stay with my LS6 manifold... going to buy some PP Stage 2 68cc heads.... my Static CR will be right at 8.63:1. I think this will allow some good boost levels on pumpgas!

Bought the Versafueler with the 96lb injectors...

CAM Advice please!!! Hmmmm dont know how I forgot to ask for cam advice. I need a good turbo cam.... taking into account the turbo, and slightly increased backpressure due to rear mounting. Thoughts?
WHy dont you have Erik grind you one...He knows the engine and knows your setup...Its pretty much common sense here.

Mike the factor is fuel consumption. My 60#ers referenced 1:1 is still @ 108% duty cycle by the end of my runs. This is with a aftermarket fuel system also and a good pump. And these injectors have been running fine @ 80 psi also.

Im asking why he has to have full tank dude...I dont car what injectors are in it.

108% duty cycle can still run fine on 3-4 gallons of gas with a properly sumped tank and fuel setup.

its because his tank doesnt have baffles in it so if it isnt full when he hits the brakes at the end of the track his car will cut off. NOT GOOD.

I hope the th400 you bought has a t-brake in it. if not, install one before it goes in the car.

you don't need no stinkin' overdrive with a th400, 2.73 or 3.08 gears and a tighter turbo friendly converter. I run 3.50 gears with 31" tires. the car 60's in the low 1.3x's and still cruises hwy speed at around 2300rpms.

contrary to popular belief, you don't need a loose converter to build boost. if it is loose enough to make any boost against the footbrake, you will blow through it on the big end. my fuddle racing converter won't even go 2800 on the footbrake, let alone make any boost at all. but lock the t-brake and activate the 2-step and it will launch at 4800 on 12psi. it took a little trial and error for John and I to get the converter right, but it works great on the track and is tight on the street. a t-brake is the best thing you will ever do for a turbo car if you want any kind of numbers at the track.

It has no baffles to control front to rear movement, I figured just looking at the tank it wasnt going to work under hard braking but I tried it anyhow. Under accleration its probably ok since the sump is well placed for that. I didnt buy it new (even though it was brand new) so not much I can but mention it and maybe they will take the 5 minutes to baffle the things from now on. Luckily I have an old speed inc aluminum tank here that is well baffled and whenever I get around to welding up the hole in the top for a 99 sender I'll use that one.

Thanks for taking the time to respond to exactly what i was asking. Seems we have a lot of specualtors wanting to post about stuff that isnt even close to what was wrong.

Now, when I sumped my tank, i used a Comp Engineering setup. 1/2 fittings etc....

I took the template they provided and drilled the 5-2" or 2.5" holes like they suggested. Ive run my tank til it was nearly bone dry. Never had an issue with the A1000 ran down that low or nothing. I know what you mean about buying 2nd hand parts though. Sometimes people just do things half *** and it hurts them or someone in the long run when its all said and done. The stock 98 tanks have decent baffling in them as it is, so I drilled the holes and welded the sump around it. Love it. You get that good tank in there the car is going to pick up when you dont have to carry all that gas around down the track..

Fuel Consumption? Doesnt sound like it here, its okay young buck. You got lots to learn.
