i have an 88' na that i have been working on for a good time now...
street port, 50 series webber, 3mm seals, turbo ii drivetrain, holley red fuel pump, water jacket mods, deeper oil grooves in the rotors, msd, electric fans, ....i think thats about it

need some guesses on horsepower output and sugg. on how much spray i can use or if using a 6.5l diesel turbo with 7psi will work

Go dyno it. Why guess, when you can get the actual numbers.

any ideas on the other half of the post?

I would not recommend a turbo from a diesel. Have you seen how massive the hotside is? It would take forever to spool, and make the powerband too narrow. Not to mention the issues with flanges.

Plus it is cheaper to get an eBay manifold, or a TII manifold.

Of course, if you are wanting to do a 6 port turbo, you have alot more work to do than you think!

Did you use 6port irons or 4port irons when you built the engine?

NOS is cheaper and easier IMHO.

HP is tough to say really, aside from the SP and carb setup the rest of the mods dont really add much HP and its hard to judge how big the SP is. I'll guess 160-180whp, but as VEX said, dyno it to really know...

4 port irons

I believe he used 12A plates....I told him as far as I was aware, with a massive streetport, he still would probably see 200-220whp at most with everything absolutely perfect, but wasn't sure.

[88moneypit]

what size shot?

See if you can talk to this guy....

thanks again...i just sent him a message.....another option.... can i just run 7psi on a stock turbo ii setup?

[WE3RX7]

7psi is within the comfort zone for a stock T2 setup... NOS would still be much easier/cheaper, lol.

You may get up to 200whp NA w/ the 4 port irons a big enough SP, but its a stretch... good luck and keep us posted though!

[88moneypit]

will i get an extra 100hp out of 7 psi....?

[85rx-7gsl-se]

Stock 13BT(TII motor) on 7-8psi is 185-205hp at the e-shaft.

[drewski86]

It all comes down to tuning. People run 300+ shots through rotarys all the time.

There's no way to know how much horse power you will get from 7 psi. Different turbos flow different amounts of air at the same boost levels. That being said, I doubt 7 psi. from any turbo will give you 100hp. Can you give specs on the turbo?

^I think he was considering a stock TII turbo
