SR Turbo-lovers,

I soon may join your ranks...I'm thinking of dropping in a BB DET to replace my slowly-dying engine (low oil pressure and metal chunks in the oil pan
).

I've priced it out from Chris at SR20 Dev and we had a good conversation. Basically, if I do this, I'll be going with the DET, IC relo kit, and 2.5" DP. I'm not sure if I should get the TTZ fuel pump as I plan to keep the boost stock until I get a cool boost controller (my stock fuel pump is less than 30K miles old). I have some parts from my NA/NOS application that I was wondering if I could use on the DET.

S3 cams - I know they'll make power, but how much more? Anyone have a dyno run from stock DET cams to S3 (or even S4) cams? If the gains are less than 10-15 hp, then I'll consider selling them to save up for a bigger turbo.


ZEX lightened flywheel - This thing has been sitting in my room for a few months now, but how effective will this thing be on a DET? Anyone run a lightened flywheel with the turbo motor?

Thanks for the input guys...

You probably don't need a different fuel pump if you're running stock boost. I don't think it becomes an issue till you're over 250 HP. I don't know how much difference S3 cams will make. I have a JUN ultralight flywheel on my turbo SE-R, I really like it.

Thanks Zak...I'll make sure to swap flywheels if I do the swap.

The S3s I'm going back and forth on...tough decision.

Mel - just call up sr20 dev and talk to him, he's really easy to talk to and he'll help you reach your power goals. 619-69-TURBO

How are you planning in registering the car in CA? I thought we couldn't pass a smog check with that engine..

I'm quite sure (but not positive) that a SR20DET could pass the sniffer test, using gas additives and a cat, but the visual won't pass. Just go to a ghetto smog check station and put a shiny green bill on the valve cover. I'm sure you'll pass then.
Well, that's how I'm planning on passing.

Hehehe...I have a loophole that I'll try to use for as long as I can. The car is actually registered in Chicago, IL (where I'm originally from). So, no annoying CA smog checks for me.


However, I have heard of SR20DETs passing out the pipe on CA's strict smog test. I'm not sure what they were using for fuel mgmt, but I'll be using a JWT ECU, so I'm sure I'll be fine.

I don't remember who it was, but it was a T3/TO4E setup I believe that a guy gained 50hp or go going from stock cams to S3s. A stock BB DET would be somewhere between the normal NA gain and that turbo gain. It should be more than 10-15hp for a turbo car from just that one data point. I'd plan on the S3s, but if you don't have the cash upfront, wait til later.
