B20LS-T

Im building a B18b sleeved to 84.5mm with ls head, fully built. What size turbo do you recommend for this? I was thinking of going with a 60-1, but not sure what trim to get. I will be boosting 15psi on the street and 20+ on the track. Thanks for your input.

If you are worried about lag and just want a nice spooling street car get a
T3/T04E:
.63 A/R Turbine Housing
Stage III Turbine

.50 A/R Compressor Housing
50 Trim Compressor Wheel

This turbo should be able to support 350 whp without any major problems!


If lag is not an issue and you want Crazy Top End go with a
T3/T04E:
.82 A/R Turbine Housing
Stage III Turbine

.60 A/R Compressor Housing
60 Trim Compressor Wheel

This turbo will support 450 whp! It will spool around 3500-3800 rpms and you should be able to have full boost by 4500-4800 rpms with 8.5:1 CR. If you have higher CR then the lag will be less!

Louis: how will it spool with a 60-1 / T3 stageIII .63 on a b20?

ArizonaTurbo

If you notice on turbonetics website, they have no compressor maps listed on their site; wonder why? The T04B 60-1 is a very inefficient compressor, thus eliminating Turbonetics need to post it on their site. The T04B 60-1 is a very old compressor. You may be able to produce 350 whp with it, but the turbo will be mismatched as the compressor will be very big and the .63 A/R turbine housing will be NOT Small, but not proportioned!

I dunno man but im really debating throwing a soch greddy kit on the wifes CR-V. what ya think?

ArizonaTurbo

I wouldn't advise it! That TD-O4 is tiny! It will fall off before it even gets started! If you are looking at doing a low boost quick response turbo kit on the CRV, why not get an HKS B series cast manifold, a Garrett T28, some 310cc injectors, a nice front mount intercooler and 8:1 FMU? You can support 300 whp with a nice size T28 and still have nice response!

Thanks for the replys, it helps a lot. Im reading a book called maximum boost, but It doesnt explain it very well. Thanks again Im getting in on the garret group buy

turboex

yeah maybe the greddy is a bit small for the cr-v but i just want a little more pull out of it on the highway. those turbos work fine on dsm and there 2.0s. pluss for the price of them kits on ebay, its a steal. oh and the cr-v is an automatic. hell ill do another ls/vtec setup that cheep to and worked great on the crx

This turbo should be able to support 350-400 whp!

T3/T04E

T3
.63 A/R Turbine Housing
Stage III Turbine

T04E
.60 A/R Compressor Housing
60 Trim Compressor

You can help eliminate lag by sending the exhaust housing to Extrude Hone or getting a ball bearing center section!

Ray

how bad is the lag for that turbo?

ArizonaTurbo

You should have full boost by 4000 rpms!
