88mm too big ?

Here's the deal, thinking about building a 363 c.i. (302) motor using a Dart Iron Eagle block, not sure on compression yet but I know it'll be low. So here's my questions, what AFR heads should I run, who to order a custom turbo camshaft from, what gear 3.27 or a 3.55 ? Also, is a 88mm gonna be too big to run on this combo or should I go with a 76mm ? Who can I get a complete kit from, intercooler/hot cold side/ BOV, WG etc etc etc ? This motor will be carbed which I am currently running a 750 Race Demon. Diamond pistons ? Any help is appreciated.

The 88 is perfect and I would not go any smaller. I ran a gt47-88 with a .96 ar housing on my 327, I just went to a 94mm though. Don't go below 9:1 compression and use a great, not mediocre, tuner. You can go even higher on comp with the right people involved.

I would use a 1.08 ar exhaust housing for your combo.
Call Jose at Forced Inductions for the right turbo for your combo.

A gt47-88 would be great as well as a pt88. The Garretts make more power imo.

I'm happy with my custom cam from Turbo People and would recommend him again.

As far as your heads, get a recommendation from Bennett Racing, I've had one of his cams too and it worked out very well.

Definately 3.27 gears.

Finally, look into BG turbo systems for a complete kit. Brian has a great reputation.

With an 88, you see looking at 1000-1100 rwhp and low low 8 second ets.

Good luck with it all and really consider injection.

That was the turbo I was looking at, the GT47-88 as well as the PT-88. I've heard alot of good things about Turbo People and CamMotion too. I have spoken with Brian before but I'll definitely give him a call back, he was a really helpful guy. I'd love to do FI but geez it's expensive plus I already have the majority of the parts to go carb. Thanks for your reply and all the helpful info.

Youre welcome,
Here is my second pass of the trailer with the GT47-88. My first day with it.

Your motor is a little bigger than mine so it may benefit from the larger exhaust wheel of the PT88, but to get an unbiased opinion, call Turbo People or Forced Inductions. When you deal with companies that sell every brand, you will get the right turbo for you, not them.

I agree with Will. Also try turbomustangs.com I found the site great. It has thoroughly increased my knowledge on the turbo.

Before anyone can give you a real answer you have to state your goals: street/race/both, HP, ET etc...

Street or race, the 88 is awesome...

Based on him wanting to know if the 88 is too big for the rest of the parts, its safe to assume he wants 1000 rwhp.

I wouldnt want to discredit him and assume that he has no idea what power that size turbo is good for, and how fast he could go with it.

If the question was "what turbo for my combo" I would have probed further.

Actually both, street and race. I do want a 1000rwhp maybe a little more that's the main reason I was asking about the 88mm. I was also figuring this turbo would definitely be good for mid-low 8's which is right where I want to be. Thanks Will for all of your help and thanks to all the other guys that replied too.

Twin 62-1's might be a good combo also.

I think that pass was 24lbs, but I hit the rev limiter on the 1-2 shift.

With about 26lbs I went [email protected] but I blew the tires off and went a 1.45 60ft so you know it was an easy 30, and possible a .20 pass.

You'd surprised how much easier it can be to run twin 3" downpipes
instead of a single 5" .............

Good luck, sounds like an awesome plan you have going here.

will posted some great info.
there's some advantages to twins. you can usually get 2 smaller turbos for less than one 88, packaging is easier, big w/g's get expensive in a hurry, and d/p routing will be easier.

Whats up man?

You were the guy who stuck up for me when I was getting flamed the last time I posted in the 5.0 tech section...

You would think I learned my lesson, but it happened again the other day.

Will your just a trouble maker. Can't help that your a product of your enviornment,lol.

Anyway a single 88 is the way to go for both street and strip. Yes twins look cool but two of everything just means twice the price, the headache and trouble shooting imo. <--------before anyone starts blasting please see the inserted(imo)

pt88 is going on my big bore dart 363.... I'm worried about it being too SMALL....


The big bore is going to move a #### ton of air... esp if you put a good flowing head on it.... the pt88 or gt4788 will work great with it...
