help with turbo build to begin I have a full setup car with all the goodies already.
I want to do a s88-s91 turbo but it still be streetable. with truck manifolds
motor
Motor I was thinking a 402 or 408 or whatever to get close to 7s. I dont know what head to run I was thinking about the darts because they are cheap. Also what head gaskets is everyone running. I am going to have LME or eric build the motor and will go with their recomendations but any info would be great. I am going to run a ported victor on it also.
computer, fuel
The problem is I have a 98 car and I wont pay for a bs3 or fast system. I dont know what to do with it. I was thinking about upgrading the computer to a 99+ but would like to just keep the 98 I know people have run high boost with them before the question is how. For fuel I was going to try the new 79lbs racetronics injectors. I will be running a 10an fuel line and a big magnafuel pump.
tranny
I dont know if I should run a glide or a th400. I am going to have yank redo my nitrous converter to reuse it. I am open to any opinions on this.
boost controller, wastegate, bov
Who makes a good one that can be ramped since this will be a radial car.
I was going to use the turbo smart 48mm wastegate it seems to be popular. the bov I have no clue which one to buy.
cooling
will my messire race pump that only pushes 35gpm be enough or should I just go back to a stock pump?
the car with turbo stuff with a iron block should be under 2900 pounds

I would say a s91 on a 402/408 will make enough power to hit the goal. Transmission is a personal preference, either will do the job if built correctly, some prefer to shift once, some dont mind shifting twice.
Wastegate would depend on how low of boost you want to run, alot of people use tial bov's and the big procharger .
If I was in your shoes, I would repin the 98 harness install a 99-02 pcm and have the many many benefits of a 99+ car. I have done this to several cars, and its not that time consuming.
The race pump will be fine for racing, but how does the car cool now? Is it driveable now? I would say you should be able to make that pump work, just have to have a good fan/radiator set-up.

I didnt drive the car much with the race pump before. I think I am going to put a stock one on the car.
I wonder at what rpm a s91 on a 408 would run out of steam.

Running out of steam on the 408 will depend on cam and heads. Also I would stay away from the darts if you want to keep the heads down. Allpro or AFR would be my choice. The s91 would be fine with a hydraulic cam cause I do not think you would be much over 6500rpm with that many cubes and that turbo to make the power you want.

Well you could try to find some used ones. It will win in the long run for price and aggravation though. If you are really trying to save money I would just run some 317's. Should be a really cool build with a 88 or 91. I think with the smaller motor you will still have the same troubles though. You will be running more cylinder pressure to make the same power.

yes I wonder if stock ported 317 could hold down to make at least 1100rwhp though a glide or th400.
now the question is a2a or a2w? It is a 70% street car. Who makes them?

I'm looking at doing a smilier setup with a 98 as well. When repinning the pcm do you need a 99 up harness as well? Then an injector driver, 2 step, wideband, hp tuners correct? The cost would be close to BS3 I think in the end. What boost are you looking at? If you're not going to be boosting to the moon at the track all the time a set of stage 3 patriot 6.0's should work and save some cash. If not I'd go with etp, afr or all pro's for the thicker deck. Not sure on the injectors but I'd say you will need 96lb at least. I think the magnafuel 4303(i think) is a big street pump that supports alot of hp. Tial wastegate and bov should be sufficient. Also I'd think a 4" A2A intercooler should work well.

Okay. From an honest standpoint on your goals. I build these setups.
-Your fuel system needs alot more injector for 1000rwhp. 79lb injectors are not gonna cut it.
-The 98 PCM needs to be yanked for a BS3 setup. Set it up and let the BS3 keep the tune in line in Real Time.
-The trans is a personal choice. Th400 for streetabilty. Glide for full on track car.
-AMS 1000 Boost Controller. JGS 56mm BOV and 60mm WG.
-Your electric pump will be fine.
It is gonna be a pain getting the numbers you want and remain streetable on the fuel system you listed and the 98 PCM. Even with the 408 and a S91 you will need 20+lbs of boost. The 98 PCM only has 2 Bar MAP capability. That alone limits you to 14.7lbs of boost.
You have set a lofty goal. It is completly doable. You are just gonna have to make some changes to your parts line up or back down your goals some. Feel Free to give me a call or PM if you would like to discuss your setup further.

He stated it. The 98 pcm can only see 2 bar map, which means the most boost you could ever run on a 98 is 14.7, anything more the ecu would screw it up.
Is there any reason someone couldn't get your kit josh, and run 7-8 psi or so on a 98 with stock ecu?
Thanks, Chris
