DatsunBoy77 Posted January 21, 2004 Share Posted January 21, 2004 Ok, i have been doing a complete restore over that few months and i have started tearing down my engine. Now i am breaking into all parts of this engine, and i building it for 400whp. I only have about half on my parts right now, but i mean i am changing everything. Well my friend has a cheap turbo he bought for his honda that was too big for it and wouldnt get fully spooled to like 4500 on a stock 1.5 that is. It is a straight T4. He gave it to me for $150. I am not sure if i just want to make it a hybrid of just keep it as a T4. The specs are: -TO4B .60 A/R compressor and 1.15 A/R turbine with a divided T4 flange for quicker spool up. Plus it runs a v-band clamp for a 3" downpipe. The turbine seems very big, but i am thinking since it is divided and is suppose to spool quicker it will help. As of right now I have a SS tubular turbo manifold, external wastegate, Turbo II cam from MSA, Megasquirt. I have a spare head right now i am porting and polishing, I havent decided on if i am going to run larger pistons yet, though. And i also plan to be running a custom intake manifold. I still have to choose injectors though. Damn i am babbling on. Does anyone have any experiances with that large of a turbo. Here is one just like it on ebay http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=2454496017&category=33742 Ryan Quote Link to comment Share on other sites More sharing options...
Brad-ManQ45 Posted January 21, 2004 Share Posted January 21, 2004 The stock AR (T3) is .63. You might get away with .8x if you have a good exhaust header that actually runs 2 sets of 3 cylinders to the divided housing...maybe near stock boost response. Even with this proper turbo header, you'll be on up there in rpms for boost to start w/the 1.15. Quote Link to comment Share on other sites More sharing options...
