I was wondering if I could get some opinions on this. I have a built 2.0L b18c 9:1 compression and have been in the market for a turbo kit for some time now. I came across a guy selling an Inline Pro kit and he had upgraded the turbo to a GT40R 74mm.



Obviously this is a large turbo, would anyone happen to know when in the rpm range this would actually start building boost and when it would hit full boost? I don't want my car to be a slug all the way up to 6000 rpm.



Other question is, if I bought the kit how much does just the turbo go for? thanks for your insight.

 

ask tony1 and turbo-charged about that turbo that and the 4088. the only on i have seen have success with that huffer was fergie.

 

Check this dyno graph and decide from that. http://forums.evans-tuning.com...=4714 Pretty similar in displacement. Peak torque isnt hit til 6500-700 rpms. What are your power goals? If they arent over 700whp then its a waste of a turbo...That turbo goes for about 1700-1800 depending on exactly which one it is.

thanks for all the responses and the dyno plot. I think im going through with it and will purchase the kit. Later on down the road maybe ill sell it and get a little smaller one with a better powerband.

on that page similar displacement engine running a non-bearing GT42 and much bigger exhaust housing have a better spool that the GT4088R mentioned in the earlier post, thats really confused the hell out of me

I ment 74mm but I think that was the exhaust side, to be honest not really sure. Ill talk to the guy about what exactly what it is. Thanks for the info though.

 

thats the spec of GT40R
