Help Me Choose A Turbo
I dont want anyone flaming me as im interested in the opinions of others. i have a 87 TII with a JSpec S5 TII engine. im looking to get 500rwhp with a large streetport. but i wanna run this kit for a year or two without the port. i was wondering what turbo everyone would choose to hit 500rwhp on a large streetport. Im gonna be running the Haltech E6X. I wanna buy from Street Machine Performance as i had good history with them and i narrowed it down to a few from this selection. please tell me which you would choose and why. thanks alot for all your help guys.

T-72, TA45, T78, or a GT42R are all excellent choices, but you're going to have to push some pretty serious boost (20+ psi) to make 500 rwhp. If you have to buy one of the turbos listed on that page to make 500 rwhp, I would go with one of the GT42 variants. Though you (and your wallet) might be more than happy with a GT35R making 450 rwhp.

thanks ian, dont ask me why but as long as iv known rotaries i was under the impression i had to do a port and rebuild to put on a kit. thats why i wasnt wild about it. so now im gonna make my own kit and run it for a year before doing the large streetport and rebuild.

i dont understand why the GT35R is $1799 and the GT42 is $1049 when the 42 can hold ALOT more hp, does watercooled make that much of a difference?

I would not suggest getting a e6x. I have one and it gave us problems for 6 months. Alot of forum members have had to ship their back to AUS to get fixed. Get a used e6k and most of the time it will come with the harness for plug and play. Don't make it hard on yourself trust me. And for a turbo I would suggest something from Precision turbo. A few forum members have hit 500 with 2nd gen motors with thier pT67 and pT74. Their is a 10 day wait on these now. Ask me how I know. Oh and if no one told you, on a dual ball bearing rebuilds are not cheap and easy. You just buy another dual ball bearing turbo. Something to consider

anywhere..
gotham has the gr63 or 67 (i think) kit
aspec has the 35 or 40r kit
rx7store has a bunch of stuff..
i got a really good deal on a new 35/40, then got a discontinued blitz manifold for $500, and found a used hks standard wastegate, oil feed and return lines, and downpipe for a few hundred bucks. my whole setup cost me around $2100.. i might have to have the dp modded a bit, but even with that and welding the w/g flange on, it MIGHT come out to 22-2300ish.
if you'e willing to get some parts used, you'll save a bundle. my turbo and manifold are new, but what's the difference between a new and used oil line...just as long as it doesn't leak. it's not really a "wearable" item.
the manifold i got--to answer your question, was from a blitz fc turbo kit that never came to pass. brian galloway (japan2la) had a few of them and i got the last one. he might be able to order you one though. it just might be a little more expensive because it's gotta get shipped in from japan. it's got some wierd 3 bolt wastegate flange on it and it IS for an fc.. i figured if it doesn't fit correctly, i'd cut the pipes and tilt it over--no biggie.
you can get a lot of power reliably if you know WHERE to compromise.
i think a 35r is a little on the small side for 500whp, but lots of guys make 400ish with low boost levels on pump gas. maybe a 40r or t61 might be a little more along the lines you're looking for, but i don't know how much room you want to grow.
