i got an email back from gpopshop. they recommended not running a 5 bolt turbo with an external wastegate because it causes turbulence. and the 4 bolt turbos wont work on the inline pro manifold since it only comes as a 5 bolt.

 

i googled it.....

seems like the inline pro manifold puts the turbo too close to the block with the 5 bolt design.

 

PM the shodan about inline pro manifolds and the 4 or 5 bolt with b or e compressor covers. if i remember right the 4 bolt ***** the compressor cover right into the block. i remember him mentioning that i had to have a 5 bolt in order for everything to fit easily

 

can you explain the difference between the compressor covers?

 

physical size, i WISH i could find the link to the actual size of all the compressor covers. the b is slightly smaller than the e

there is a compressor cover size chart somewhere but i have no clue where i saw it. tried to google it with no luck

 

Turbulence with a 5 bolt hounding vs 4. Whoever you talked to was a moron.

 

ok.... care to share a little light on the subject then? lol

 

i've been curious about which style to use and the only thing i can really find is that on a 5 bolt turbo you run an internally wastegated turbo. this allows you to run the external wastegate on the downpipe flange if space is an issue (shouldn't be an issue with a turbo this small). also, 5 bolt turbos have more issues with boost creep (again, shouldnt be an issue with this size). 5 bolts seem to spool faster and have better midrange for a very small margin in top end. with all else equal, i'm staying with the 5 bolt.

read this. good info on it.

i dont understand why you are making this setup so complicated man... you are all over the place on desiding what to use... research turbos piping size and so on. hell just put a gt28 on it with 2 inch piping if that. 350hp rated intercooler 38mm wastegate bov and so on. its way easier than you are making it to get to 300-350. at the same time did you even consider thinking bout the fuel system and how your gonna tune it? i would think you would know a lil more about this subject seeing you said you had a 350hp rsx? i mean i dosent seem like you are competeing and you just want a lil extra power.

 

200 rsx type s (sold)
350 genesis coupe 3.6 (not mine)

i've never played with turbo's before. this is new territory so i'd like to get it right.

 

That's a key statement.

Here's your answer/solution:
http://www.amazon.com/Turbocharging-...9524053&sr=8-1

It is essential reading for those wanting to get it right. It's easy to read, aka lot's of pics & diagrams as well as case studies on vehicles. It is written to show u how to choose a turbo, intercooler etc, how to choose engine mgmt/boost control.

For 20 bux and a week of your time it will save u from a busted or underperforming car. I wish I had it the 1st time I did a DIY turbo conv. The Turbo was great ..so great in fact (18psi), the fueling went lean and melted my valves.

 

same with reading dyno charts and having an actual goal

in my case i have a b18c and wanted

1. 300whp
2. the ability to maintain a full size radiator
3. reliability was a larger concern than whp

in my case that meant an inline pro and precision 5431b. there are other turbos i could have used but imo this is a best value for the goal i had. the small case and no cost option to go 5 bolt was a bonus.

different goals will require a different parts selection

 

i'll take your word on that. thanks for looking out. sorry for your loss. hopefully you could rebuild it.

 

did you hear anything back from the shodan?

 

yea, i talked to him like a month ago. posted most of what i learned. if you want the exact reason the inline requires a 5 bolt shoot him a pm, i just remember it was clearance related

 

here's my answer. thanks

when i start building i'd like to come back to this thread for some kind of reference so here's cooling too lol

i mentioned looking for the right intercooler diameter piping earlier. this thread was very helpful.

you found two really good threads, also reminded me what the deal was with the 5 bolt. i knew there was a reason, just couldn't remember what it was yesterday
